PURPOSE Tumor invasion to the portal vein (PV) or superior mesenteric vein (SMV) can be encountered during the surgery for pancreatic cancer. Venous reconstruction is required, but the optimal surgical methods and conduits remain in controversies. METHODS From January 2007 to July 2012, 16 venous reconstructions were performed during surgery for pancreatic cancer in 14 patients. We analyzed t...

Microvascular surgery for the reconstruction of the hepatic artery in living donor liver transplantation is discussed from the microsurgeon's point of view. A refined operative procedure to improve the safety of the anastomosis is described. In living donor liver transplantation, the hepatic artery of the graft is short and small, the operative site is deep and mobile, and the anatomic arrangem...

BACKGROUND In this study, the relationship between patency of saphenous vein (SV) graft and different sizes of aorta wall punches was investigated during the follow-up period after coronary artery bypass graft surgery. We also evaluated the other possible factors affecting SV graft patency. METHODS This study consisted of 266 consecutive and symptomatic patients with postoperative angiography...

The conventional elective open procedures for abdominal aortic aneurysm repair are reliable and yield durable results. The aortoaortic tube graft has the lowest morbidity incidence when compared with different techniques. Albeit infrequent, thrombosis can be present in the first 30 days. Its treatment consists in thrombectomy and anastomosis evaluation, but with an increase in morbidity, especi...

We report for the first time two cases of vein graft spasm following distal artery bypass in the lower extremity. In the first case, graft spasm occurred in the region just distal to the proximal anastomosis and it resolved without surgical intervention. In the second case, completion angiography showed defective filling around the distal anastomosis. We considered this to be due to technical e...

Acute thrombotic occlusion of an aortocoronary bypass graft to the left anterior descending coronary artery (LAD) was successfully dissolved by selective infusion of streptokinase into the graft at 2000 U/min for 1 hour via catheter. There was partial recanalization of the graft and complete filling of the LAD within 15 minutes. After 1 hour of lysis, the graft was completely patent, although h...

in this paper, two patients with severe dysphagia and esophageal stricture secondary to epidermolysis bullosa are presented and discussed. they are siblings of an affected family. primary resection and anastomosis had been performed previously in both patients, but dysphagia had recurred. we treated these patients with free jejunal graft to the esophagus with excellent results. both patients ar...

Pseudoaneurysm of the ascending aorta after cardiac surgery is a rare but life threatening complication, which can result in rupture. Pseudoaneurysms are usually related to the aortic cannulation, the proximal site of graft anastomosis, or the suture line of aortotomy, and often occur after mediastinal infection. We report a case of pseudoaneurysm of the ascending aorta associated with aortic c...

UNLABELLED 62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral cir...

PURPOSE One current method of anastomosis in aortic dissection type A is the adventitial inversion technique. To improve hemostasis at the anastomotic site, we have developed a novel technique for distal anastomosis involving adventitial inversion employing graft telescopic insertion. METHODS The adventitia was inverted into the aortic lumen and the anastomosis with a Dacron tube-graft was ma...
