Retinal vein occlusions (RVO) are the second commonest sight threatening vascular disorder. Branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO) are the two basic types of vein occlusion. Branch retinal vein occlusion is three times more common than central retinal vein occlusion and- second only to diabetic retinopathy as the most common retinal vascular cause of visu...

BACKGROUND In the past decade, the radial artery has frequently been used for coronary bypass surgery despite concern regarding the possibility of graft spasm. Graft patency is a key predictor of long-term survival. We therefore sought to determine the relative patency rate of radial-artery and saphenous-vein grafts in a randomized trial in which we controlled for bias in the selection of patie...

Puroose: Proliferative diabetic retinopathy is assumed to develop because vasogenic factors are released from retinal areas that are ischaemic and hypoxic secondary to occlusion of the retinal vascular bed. It has been propclsed that vascular occlusion in diabetic retinopethy may be due to the deposition of periodic acid Schiff positive glycoprotein compounds in the retinal vascular walls. but ...

The internal thoracic artery (ITA) is the conduit of choice for coronary artery bypass grafting (CABG). This study, utilizing a canine model, evaluates cryopreserved ITA. Sixteen ITAs were harvested and cryopreserved according to United CryoInstitute protocol. Test conduits, 5 cm long and 4 mm mean diameter, were anastomosed to the ligated carotid artery of an unmatched mongrel recipient, above...

BACKGROUND Acute thrombosis of a transplanted renal artery is a serious vascular complication following renal allograft transplantation, which usually occurs within the first month after transplantation and often results in graft loss. It rarely occurs beyond the first month, except in a rejected kidney or in a kidney with high-grade transplant renal artery stenosis. RESULT A 65-year-old male...

The purpose of this study was to evaluate the efficacy of combined ipsilateral percutaneous iliac angioplasty and open infrainguinal surgical techniques for the treatment of patients with multilevel arterial occlusive disease. Combining two types of approaches in the peripheral vascular field is a less aggressive technique and may result in excellent early patency and limb salvage rates. We rep...

Methods A 66-year-old man was admitted to our hospital on November 11, 2012. He had a painful, pulseless, and cold below-knee in right lower extremity. He had previous right cross-over composite sequential femoropopliteal bypass. Angiography showed acute occlusion of cross-over composite femoro-popliteal bypass graft and stent graft used in treatment of pseudoaneurysm developing in popliteal an...

A total of 55 consecutive patients who experienced perioperative myocardial infarction (MI) after coronary artery bypass grafting were studied using multislice computed tomography (MSCT) angiography to evaluate for graft patency. The MSCT detected acute graft occlusion in 23% grafts. Of the 55 patients, 40% patients had occluded grafts and perioperative MI in the area of the grafted vessels; re...
