Although intraoperative hemorrhage is a well-recognized complication of open partial nephrectomy, postoperative hemorrhage caused by a renal artery pseudoaneurysm (RAP) after open partial nephrectomy is rare. We presented a case of RAP occurring in an 84-year-old man 3 weeks after right open partial nephrectomy for renal cell carcinoma. The pseudoaneurysmal ...

BACKGROUND: A kidney with a single artery is preferred for donation. We wondered how often the donor is left with double or triple arteries, and whether this has any implications for long-term kidney function. METHODS: The consecutive living donors from 1984 to 1988 were reevaluated for kidney function and outcome. ...

BACKGROUND: Cardiologists often identify atherosclerotic renal artery stenosis (ARAS) during cardiac angiography. The importance of such 'incidental' ARAS (iARAS) is not known. The present study sought to describe renal perfusion using non-captopril (baseline) nuclear renograms in patients with iARAS, and to determine characteristics associated with a positive captopril renogram. METHODS: ...

Neurofibromatosis is associated with mid-aortic dysplasia, renal artery aneurysms and renal artery ostial stenosis, or occlusions in about 1% of cases. We describe a novel approach to recanalize an occluded renal artery in a 10-year-old girl with neurofibromatosis and difficulty in pharmacologically controlling her hypertension. Normally, when reconstruction is required, ...

Renal artery stenosis (RAS) is a potentially curable cause of renovascular hypertension (RVH) and is caused by either atherosclerosis or fibromuscular dysplasia in the vast majority of patients. Although intra-arterial digital subtraction angiography is still considered the standard of reference test for the anatomic diagnosis of RAS, MR angiography and ...

The prevalence of atherosclerotic renal artery disease has increased with improved life expectancy. Because renal artery stenosis is a potentially correctable cause of hypertension and ischemic nephropathy, early identification of this entity may lead to proper hypertension control and improved renal function and survival. The aim of this study was ...

Renal artery aneurysms are being discovered more frequently due to increased use of non-invasive imaging. Complex renal artery aneurysms involving multiple secondary or tertiary branches are not amenable to in vivo or endovascular treatment and often require ex vivo repair with autotransplantation. In order to minimize incisional morbidity and hasten ...

Fibromuscular dysplasia (FMD) is one of the most common causes of renovascular hypertension in children and women. It is characterized by short multiple stenoses alternated to focal expansions that usually involve the lateral third of the renal artery. Digital subtraction angiography is considered the most accurate method in the diagnosis ...
