Methods From October 2002 to December 2008, 208 patients （196 males and 12 females） underwent OPCABG using a BIMA Y configuration graft. The average age of the patients was 56.5 ± 11.3 years, with an age range of 33-78 years. A total of 167 （80.2%） cases had triple-vessel disease. Left main stem disease was found in 33 （15.9%） cases, and double-vessel disease was found in 8 （3.9%） cases. The semi-skeletonization technique was used to harvest the two internal mammary arteries （IMAs）, and then the free right internal mammary artery was connected end-to-side to the left internal mammary artery （LIMA） in situ to complete the Y configuration graft. Off-pump and sequential anastomosis methods were used to perform coronary artery bypass surgery in all patients. Graft patency was assessed intm-operatively with the HT311 transit time flowmeter. Results A total of 728 distal anastomoses were performed in 208 patients, with the average being 3.5± 1.3 per person. No one died or experienced recurrent angina within 30 days after the operation. Conclusions OPCABG using the BIMA Y graft was safe and effective to achieve total arterial revascularization. This method avoids surgical operation on the ascending aorta and other incisions.展开更多

He had a history of occasional chest pain more than one year. Angiography didn＇t reveal significant stenosis at coronary artery. The patient was found a continuous grade 2/6 murmur over the left upper parastenal area one month ago. Chest MRA revealed a possible left superior pulmonary arteriovenous fistula. For diagnosis and localization of the fistula, aortography and selective angiography of the intemal mammary artery was performed and presented a left internal mammary artery-to-pulmonary artery fistula. The fistula was successfully closed using an 12 mm domestic vascular plug. Chest MRA showed that the fistula disappeared at two-month follow-up展开更多
