Kinking and coiling of internal carotid artery with and without associated stenosis. Surgical considerations and long-term follow-up.

Although incidence of coiling and kinking of internal carotid artery has been estimated to be from 10% to 16% in general population, respective clinical significance still remains the ground of controversy. Cerebrovascular hemodynamic changes mainly from kinking and in a lesser degree from coiling, have been documented with oculoplethysmographic and angiographic differences, accompanying positional changes of the head. The opposite view however, that similar variations represent a benign and incidental finding, has been also expressed.

Carotid artery surgery and the principle of prophylaxis: recurrence in operated and nonoperated patients.

A total of 700 carotid endarterectomies have been performed over a 24-year period at the authors' institute; of these patients 632 (90.3%) had unilateral and 68 (9.7%) had bilateral disease.

Abdominal aneurysmectomy and determinants of improved results and late survival. Surgical considerations in 672 operations and 1-15 year follow-up.

The present communication is concerned with 672 abdominal aneurysmectomies performed over a period of 24 years. All aneurysms with diameter 4 cm and above, were considered for surgery. Emphasis is given on factors determining post operative results and late survival.

Juxtarenal abdominal aneurysmectomy.

The term juxtarenal abdominal aneurysm is used to describe an aneurysm whose neck is level or adjacent to the origin of one or both renal arteries. Misinterpretation of these appearances could result in the operation being abandoned with the erroneous diagnosis of suprarenal aneurysm. We report 38 patients with a median age of 66 who underwent juxtarenal aneurysm repair, 18 of whom had been diagnosed as having an abdominal aneurysm extending above the renal arteries.

Surgical treatment of renovascular hypertension and respective late results. A twenty years experience.

This paper presents the long term results following operative reconstruction for renovascular hypertension in 115 patients operated upon over a period of 20 years. There were 71 (61.7%) males and 44 (38.
