Methods We retrospectively reviewed the medical records of patients with placenta accreta between January 2010 and August 2014. Totally 18 women(mean age 30.8±4.2 years) of primary massive postpartum hemorrhage with diagnosis of placenta accrete received treatment of UAE after delivery. Images of DSA and medical records were reviewed. Technical success was defined as control of bleeding after embolization. The complications, control of hemorrhage and recurrent bleeding of the placenta left inside the uterus were retrospectively collected for assessment. Results All patients underwent transcatheter embolization of bilateral uterine arteries. The technical success rate of embolization was 100%. Bleeding was controlled in 17 of 18 patients(94%) during follow-up period(median 18 months, 3-31months) without further bleeding recurred. One patient with placenta percreta undertook an emergent hysterectomy along with surgical bladder repair after UAE because of persistent uterine bleeding. Eight patients had postembolization syndrome and no other complications occurred. Conclusion Uterine artery embolization is an effective and safe treatment for the management of primary postpartum massive hemorrhage associated with placenta accreta.展开更多

Methods Retrospective review of 120 cases with 125 intracranial aneurysms embolized with con-trollable coils from March 1995 to July 1999 was conducted. The 20 accidents(in 18 cases) including aneurysm rupture, over-embolization, protrusion of coil end into the parent artery, and thrombosis of the parent artery were analyzed. Results Among the 20 accidents, there were 6 aneurysm ruptures, 6 over-embolizations (in 5 cases), 6 coil protrusions, and 2 thromboses (one was secondary to coil protrusion). The embolization-related mortality was 3.33% (4/120), the permanent neurological deficit was 1.67% (2/120), and the transitory neurological deficit was 3.33%(4/120). The occurrence and outcome of the complications were related to the embolizing technique, the pattern of aneurysm and its parent artery, the imperfection of embolic materials, and the observation and management during embolization. Conclusion Skilled embolizing technique, better understanding of the angio-anatomy of an aneurysm and its parent artery, correct judgement and management during embolization, and improvement of embolic materials are beneficial to the reduction of complications and to the melioration of the outcome of complications.展开更多

However, the optimal embolization techniques are still inconclusive. To further understand the roles of different embolization locations and embolic materials in SAE, we conducted this system review and meta-analyses.Methods: Clinical studies related to SAE for adult patients were researched in electronic databases, included Pub Med, Embase, Science Direct and Google Scholar Search(between October 1991 and March 2013), and relevant information was extracted. To eliminate the heterogeneity, a sensitivity analysis was conducted on two reduced study sets. Then, the pooled outcomes were compared and the quality assessments were performed using Newcastle-Ottawa Scale(NOS). The SAE success rate, incidences of life-threatening complications of different embolization techniques were compared by χ2 test in 1 st study set. Associations between different embolization techniques and clinical outcomes were evaluated by fixed-effects model in 2 nd study set.Results: Twenty-three studies were included in 1 st study set. And then, 13 of them were excluded, because lack of the necessary details of SAE. The remaining 10 studies comprised 2 nd study set, and quality assessments were performed using NOS. In 1 st set, the primary success rate is 90.1% and the incidence of life-threatening complications is 20.4%, though the cases which required surgical intervention are very few(6.4%). For different embolization locations, there was no obvious association between primary success rate and embolization location in both 1 st and 2 nd study sets(P >0.05). But in 2 nd study set, it indicated that proximal embolization reduced severe complications and complications needed surgical management. As for the embolic materials, the success rate between coil and gelfoam is not significant. However, coil is associated with a lower risk of life-threatening complications, as well as less complications requiring surgical management.Conclusion: Different embolization techniques affect the clinical outcomes of SAE. The proximal embolization is the best option due to the less life-threatening complications. For commonly embolic material, coil is superior to gelfoam for fewer severe complications and less further surgery management.展开更多

Currently, the use of angiography and embolization for the treatment of PFCMB obtains good results. The aim of this study is to observe the effects of early internal iliac artery embolization on the systemic inflammatory response syndrome(SIRS) in dogs with simulated-pelvic-fracture combined with massive bleeding.Methods: Twenty adult dogs were randomly divided into an embolization group(EG) and a control group(CG). For the two groups, heart rate, respiratory rate and body temperature and other physiological variables were measured, and IL-6, TNF-α and arterial blood gas levels were monitored. These variables were assayed every 30 min until death in the CG, while dogs in the EG underwent arterial angiography after 60 min of modeling. The internal iliac artery was embolized on the injured side.Results: The average time to SIRS in the CG was 3.56 h, occurring at a rate of 90%(9/10) within 24 h, with a mortality rate of 50%(5/10); the average time to SIRS for the EG was 5.33 h, occurring at a rate of 30%(3/10) within 24 h, with a mortality rate of 10%(1/10). When SIRS occurred in the EG, the mean plasma IL-6 level was 52.66±7.38pg/ml and the TNF-ps, tα level was 11.45±2.72ng/ml, showing a significant difference with those of the CG(P<0.05). In the two grouhe respiratory rate and leukocyte levels were higher at each monitored time after modeling than those before modeling; the mean arterial pressure, levels of hemoglobin and oxygen partial pressure were significantly lower at each time point after modeling than those before modeling except for the mean arterial pressure at 0h in EG; the platelet levels at 4 and 8h were higher than those before modeling; and the differences were statistically significant(P<0.05). In the EG, the mean arterial pressure, heart rate, respiratory rate and hemoglobin levels at 2, 4 and 8h were lower than those at 0h; the levels of leukocytes, platelets and carbon dioxide partial pressure at 4 and 8h after modeling were higher than those at 0h, and the differences were statistically significant(P<0.05, P<0.01); in the CG after modeling, the mean arterial pressure, levels of hemoglobin and carbon dioxide partial pressure at 2, 4 and 8h were lower than those at 0h; the levels of heart rate and leukocytes were higher than those before modeling; the respiratory rate and platelet levels at 4 and 8h were higher than those at 0h; and the differences were statistically significant(P<0.05). The levels of the mean arterial pressure and hemoglobin at 4 and 8h and the p H values at 8h after modeling in the EG were significantly higher than those in the CG, while the heart rate and respiratory rate at 4 and 8h were significantly lower than those in the CG. The p H values at 8h after modeling were significantly lower than those of the other monitored times in the CG(P<0.05, P<0.01). The two groups had elevated levels of alkaline phosphatase after injury induction.Conclusion: Through the use of an on-spot interventional treatment cabin, early internal iliac artery embolization can control bleeding associated with pelvic fractures, delay the occurrence of SIRS, and improve the success rate of the treatment of pelvic fracture combined with bleeding.展开更多

Methods： As the procedure SUAE for fibroids, prospective data of the initial 65 consecutive women treated from March 2007 to September 2009 were collected. The follow-up period from 1 week to 30 months, using questionnaires, we investigated the fibroid-related physical and psychological symptoms, and the cumulative rates of symptom control, gynecologic interventions, and complications. The volumes of uterine and uterine fibroids were calculated by CDUS pre- and post-SUAE for 6 months. And we tested the levels of internal hormone including FSH, LH and E2 before and after SUAE for 3, 6 months. Results： SUAE was performed successfully in all patients. There was no peri-operative morbidity in all procedures. Compared with pre-SUAE volumes of uterine [（322± 12） cm^3] and uterine fibroids [（125±46） cm^3], their volumes in post-SUAE were （144±72） cm^3 and （51 a：l 1） cm^3 （P〈0.01）, and reduction rate was 58% and 61%, respectively. At 3, 6 months after SUAE, levels of FSH, LH, and E2 were not decreased than that of in pre-SUAE （P〉0.05）. After SUAE for 24 months, the fibroids related physical and psychological symptoms such as bleeding, pain and quality of life were significantly improved （P〈0.01）. 90.8% （59/65） women had resolution of symptoms and no significant post-procedural symptoms. Parts of patients discharge necrotic fibroids. 86% （34/40） complications were minor, requiring no therapy. 9.2% （6/65） had significant post-procedural symptoms, requiring therapy in hospital or out-patient department. Conclusion： SUAE contributes to a long-term significant improvement of all investigated uterine fibroid-related symptoms and markedly improves women＇s health-related quality of life. SUAE that no impair on changes of internal hormone, under suitable conditions, represents an attractive alternative to hysterectomy for the treatment of symptomatic fibroids and is a minimally invasive, new method of good clinical prognosis. CDUS is an effective to investigate the outcome of SUAE.展开更多

Methods： The clinical records of 13 512 patients diagnosed with HCC and received TACE from January 2000 to December 2009 were reviewed. Among these patients, 5 031 were allocated into group A who had one or more disorders like diabetes, hypertension, coronary heart disease, obesity or varicose vein of lower limb, while the other 8 481 patients who did not have such disorders were in group B. Results： A total of 39 185 TACE procedures were performed for the 13 512 patients. Five （0.01%） patients in group A developed PE after TACE, of whom two recovered 4 and 5 d later with early anticoagulant therapy while the hypertension, coronary heart disease, obesity or varicose vein of lower limb are possibly more likely to develop PE other 3 died of respiratory failure within 5 h. The mortality of PE was 60% （3/5）. Conelusion： HCC patients with diabetes, after TACE than those without such disorders. Patients who have such disorders should be more carefully observed after TACE and early treatment with heparin should be applied once PE develops.展开更多

To compare the embolization effects of intracranial aneurysms with mechanical detachable spirals (MDS) and with Guglielmi detachable coils (GDC).Methods. One hundred and twenty cases with 125 intracranial aneurysms were embolized in Beijing Hospital from March 1995 to July 1999. Sixty - six aneurysms in 64 cases were embolized with MDS, 51 in 48 with GDC, and 8 in 8 with both MDS and GDC. Clinical data including sex, age, subarachnoid hemorrhage (SAH), Hunt & Hess grading, diameter and neck width of aneurysms, number and length of coils used per aneurysm, occlusive ratio, and complications were compared between MDS and GDC groups.Results. MDS and GDC groups were comparable (t-test or x2 -test, all P value > 0. 10) in terms of age, sex, diameter of aneurysms [ (8. 46 ± 3. 42) mm vs. (7. 38 ± 3. 45) mm], neck width [ (3. 49 ± 1. 50) mm vs. (3. 26 ± 1. 52) mm], coils number[ (4. 65 ± 3. 01) vs. (4. 24 ± 2. 65) ] and their length[ (460. 2 ± 398. 5) mm vs. (422. 9 ±387. 1) mm] used per aneurysm, occlusive ratio in aneurysms embolized ≥80% [ (95. 00% ± 6. 32% ) vs. (94. 19% ± 7. 63% ) ], mortality and permanent complications (7. 8% vs. 4. 2% ).Conclusions. MDS and GDC are all materials for embolization of intracranial aneurysms. MDS is less expensive, but more difficult to control and of propensity to complications while GDC is more compliant, easier to be used, safer, and have many alternative types for use as well as more extensive indications.展开更多

Methods:Forty patients with AVM were treated using microcatheterization techniques with NBCA through intravascular approach under supervision of digital subtraction angiography (DSA ). Results: of these 40 patients whoseAVMs were ernbolized 57 times, 8 were cured, 31 had significant improvement of clinical symptoms withoutrebleeding. Complications included headache, neurological dysfunction, normal perfusion pressure breakthrough. Intracranial hemorrhage occurred in one case due to rupture of an arterial feeder which required surgical operation. Visual field defect was found and did not recover in one. Conclusion:TAE with NBCA is aneffective therapeutic mesure for AVM. Domestic NBCA is of good quality and low price, therefore, it can beused to substitute for similar imported products.展开更多

And we tested the levels of internal hormone including FSH, LH and E2 before and after SUAE for 3, 6 months. Results： SUAE was performed successfully in all patients. There was no peri-operative morbidity in all procedures. Compared with pre-SUAE volumes of uterine [（322± 12） cm^3] and uterine fibroids [（125±46） cm^3], their volumes in post-SUAE were （144±72） cm^3 and （51 a：l 1） cm^3 （P〈0.01）, and reduction rate was 58% and 61%, respectively. At 3, 6 months after SUAE, levels of FSH, LH, and E2 were not decreased than that of in pre-SUAE （P〉0.05）. After SUAE for 24 months, the fibroids related physical and psychological symptoms such as bleeding, pain and quality of life were significantly improved （P〈0.01）. 90.8% （59/65） women had resolution of symptoms and no significant post-procedural symptoms. Parts of patients discharge necrotic fibroids. 86% （34/40） complications were minor, requiring no therapy. 9.2% （6/65） had significant post-procedural symptoms, requiring therapy in hospital or out-patient department. Conclusion： SUAE contributes to a long-term significant improvement of all investigated uterine fibroid-related symptoms and markedly improves women＇s health-related quality of life. SUAE that no impair on changes of internal hormone, under suitable conditions, represents an attractive alternative to hysterectomy for the treatment of symptomatic fibroids and is a minimally invasive, new method of good clinical prognosis. CDUS is an effective to investigate the outcome of SUAE.

文摘To study the clinical characteristics and treatment of pulmonary embolism （PE） after transcatheter arterial chemoembolization （TACE） for hepatocellular carcinoma （HCC）. Methods： The clinical records of 13 512 patients diagnosed with HCC and received TACE from January 2000 to December 2009 were reviewed. Among these patients, 5 031 were allocated into group A who had one or more disorders like diabetes, hypertension, coronary heart disease, obesity or varicose vein of lower limb, while the other 8 481 patients who did not have such disorders were in group B. Results： A total of 39 185 TACE procedures were performed for the 13 512 patients. Five （0.01%） patients in group A developed PE after TACE, of whom two recovered 4 and 5 d later with early anticoagulant therapy while the hypertension, coronary heart disease, obesity or varicose vein of lower limb are possibly more likely to develop PE other 3 died of respiratory failure within 5 h. The mortality of PE was 60% （3/5）. Conelusion： HCC patients with diabetes, after TACE than those without such disorders. Patients who have such disorders should be more carefully observed after TACE and early treatment with heparin should be applied once PE develops.
文摘Forty children with thalassemia major were treated with gelfoam particles for partialsplenic embolization (PSE).The embolization of the spleen ranged from 50 to 85 per cent.Af-ter PSE,the spleen shrank greatly,and the symptoms of anemia improved.The immunologicalfunction of the body was the same as before PSE.All patients showed a marked reduction intransfusion requirements.Therefore,it is believed that PSE is an effective therapy for tha-lassemia major.
文摘For further reaseach on endovascular embolization treatment of AVMs, 54 patients with AVMs treated with embolization were observed. It was found that embolization was an effective procedure for the treatment of AVMs. Combined treatment of AVMs with presurgical embolization and direct surgery could reduce the comphcations resulting from large and high flow AVMs with lone surgical removal.
文摘Objective：To evaluate the safety and efficiency of transvenous embolization of dural arteriovenous fistula of cavernous region by multiple venous routes. Methods： Twenty seven patients with dural arteriovenous fistula of cavernous region were treated by transvenous embolization with micro-coils. The transvenous routes included inferior petrosal sinus, superior ophthalmic vein and facial vein. Results： Clinical cure was achieved in 23 cases and significant improvement of symptoms in 4 cases. Complete anglographic obliteration was documented in 22 patients （82%）. Residual shunting were left in 2 patients via pterygoid drainage and 1 case via inter-cavernous sinus, 2 cases via inferior petrosal sinus, disappeared one month later by manual compression carotid artery. Headache and vomiting were the most common symptoms after embolization. Three patients had diplopia and relieved within two months after embolization. There was no permanent procedure-related morbidity. The clinic follow up ranged from 5 months to 6 years, and there was not recurrence case. Conclusion： Transvenous embolization via different venous routes is a safe and efficient method for dural arteriovenous fistula of cavernous region treatment.

文摘Objective. To compare the embolization effects of intracranial aneurysms with mechanical detachable spirals (MDS) and with Guglielmi detachable coils (GDC).Methods. One hundred and twenty cases with 125 intracranial aneurysms were embolized in Beijing Hospital from March 1995 to July 1999. Sixty - six aneurysms in 64 cases were embolized with MDS, 51 in 48 with GDC, and 8 in 8 with both MDS and GDC. Clinical data including sex, age, subarachnoid hemorrhage (SAH), Hunt & Hess grading, diameter and neck width of aneurysms, number and length of coils used per aneurysm, occlusive ratio, and complications were compared between MDS and GDC groups.Results. MDS and GDC groups were comparable (t-test or x2 -test, all P value > 0. 10) in terms of age, sex, diameter of aneurysms [ (8. 46 ± 3. 42) mm vs. (7. 38 ± 3. 45) mm], neck width [ (3. 49 ± 1. 50) mm vs. (3. 26 ± 1. 52) mm], coils number[ (4. 65 ± 3. 01) vs. (4. 24 ± 2. 65) ] and their length[ (460. 2 ± 398. 5) mm vs. (422. 9 ±387. 1) mm] used per aneurysm, occlusive ratio in aneurysms embolized ≥80% [ (95. 00% ± 6. 32% ) vs. (94. 19% ± 7. 63% ) ], mortality and permanent complications (7. 8% vs. 4. 2% ).Conclusions. MDS and GDC are all materials for embolization of intracranial aneurysms. MDS is less expensive, but more difficult to control and of propensity to complications while GDC is more compliant, easier to be used, safer, and have many alternative types for use as well as more extensive indications.
文摘Objective: To investigate the effect of transarterial embolization (TAE) at early stage postoperatively to prevent rumor recurrence after hepatectomy in patients with large hepatocellular carcinoma (HCC). Methods: Forty-five volunteer patients with large HCC received TAE 2 to 4 weeks after the hepatectomy. Another 48 patients with large HCC without postoperative TAE treatment served as control. Results: No severe complications associated with TAE or hepatectomy occurred, and follow-up visit of all patients revealed that 1-year recurrence rate for patients with PAL was markedly lower than those without (43.24%vs 70.73%, P＜0.05＝. Conclusion: The treatment with TAE at early stage after hepatectomy is safe and feasible for the patients with liver function Child-Pugh score not higher than 8, and it may help reduce the postoperative recurrence of hepatocellular carcinoma.
文摘Thrombophilia denotes a condition,whether acquired or hereditary,characterized by increased susceptibility to hypercoagulation.[1]This condition was first described in 1965,coinciding with the discovery of an inherited predisposition to venous thromboembolism(VTE)in patients deficient in antithrombin III.[2]While arterial and venous thromboses are common in hospitalized patients,acute myocardial infarction(AMI)and pulmonary embolism(PE)stand out as lifethreateningconditions.However,theoccurrenceof AMI complicated by PE is exceedingly rare,especially when considering cases where paradoxical embolism originating from a patent foramen ovale is absent.This report presents a case of AMI complicated with PE.A comprehensive understanding of the pathophysiology of this rare yet critical condition is important for ensuring prompt diagnosis and treatment.
文摘objective:To explore the characteristics and preparation of N-butyl-2 cyanoacrylate (NBCA) as anembolic material for cerebral arteriovenous malformation (AVM) and to discuss the indications, and technicalnote of transcatheter arterial embolization (TAE) and the prevention of its complications. Methods:Forty patients with AVM were treated using microcatheterization techniques with NBCA through intravascular approach under supervision of digital subtraction angiography (DSA ). Results: of these 40 patients whoseAVMs were ernbolized 57 times, 8 were cured, 31 had significant improvement of clinical symptoms withoutrebleeding. Complications included headache, neurological dysfunction, normal perfusion pressure breakthrough. Intracranial hemorrhage occurred in one case due to rupture of an arterial feeder which required surgical operation. Visual field defect was found and did not recover in one. Conclusion:TAE with NBCA is aneffective therapeutic mesure for AVM. Domestic NBCA is of good quality and low price, therefore, it can beused to substitute for similar imported products.
