Renal revascularization to preserve and restore renal function.

A total of 97 patients underwent 107 renal revascularization procedures for restoration and preservation of renal function. Of the 4 groups of high risk surgical patients that emerged an overall successful outcome was achieved in 83%, with a 6% mortality rate and an 11% morbidity rate. Renal revascularization for restoration and preservation of renal function can be performed safely with good results. The preoperative serum creatinine level was not predictive of the surgical outcome. Alternative bypass procedures are preferred.

Blue toe syndrome. Causes and management.

The sudden development of cyanotic lesions on the feet may be a result of atheroembolic disease or a number of medical conditions. A careful history and physical examination, basic laboratory tests, and noninvasive vascular assessment usually distinguish between medical and surgical causes and direct the choice of further investigations. Specific therapy is often available for medical conditions causing this syndrome. The management of atheroembolic disease is more controversial. In particular, further research is necessary to determine which patients need surgical intervention and which patients can be managed safely by medical therapy.

Peripheral aneurysms.

Peripheral atherosclerotic aneurysms occur primarily in elderly men. Major complications are arterial thromboembolism with ischemia of the limb and, rarely, rupture of the aneurysm. Vascular reconstruction is associated with a low mortality, and operation is recommended. These aneurysms are often associated with arterial ectasia at other locations. The presence of peripheral atherosclerotic aneurysms always requires a search for other peripheral aneurysms, particularly in the abdominal aorta.

Physiology of the adrenal medulla.

As can be appreciated from this discussion, catecholamines derived from the adrenal medulla have far-reaching effects on human physiology, ranging from direct effects on individual cells to participation in complex behavioral responses.

Changing concepts in surgical management of renovascular hypertension.

As newer surgical techniques and concepts have emerged, including revascularization of the totally occluded renal artery and alternatives to aortorenal bypass (hepatic, splenic, or iliac artery to renal artery grafts), our patient population has changed. Patients with diffuse atherosclerotic disease, bilateral renal artery stenosis, totally occluded renal arteries, and azotemia are being referred for renal revascularization, thereby changing the indications for operation and the results that can be anticipated. Although our results in patients operated on solely for uncontrollable hypertension or renal failure have been successful, much work needs to be done to improve the results obtained when patients have a combination of uncontrollable hypertension and renal failure.

Hepatorenal artery bypass in the management of renovascular hypertension.

Infrequently, when the aorta cannot be used for a standard renal bypass operation because of a previous aortic operation, severe degenerative atherosclerosis or complete aortic thrombosis, a unilateral (hepatic) or bilateral (hepatic and splenic) visceral bypass should be contemplated. Patients with abdominal aortic aneurysms extending above the renal arteries might benefit from concomitant bilateral visceral bypass procedures followed by aortic replacement during the same operative session. The hepatic circulation with its common anatomic variations, indications, surgical technique and effects of hepatorenal artery bypass on the renal and hepatic circulation are discussed.
