Internal carotid artery kinking is frequently accompanied by atheromatous disease at the carotid bifurcation, and in this case both lesions may be treated simultaneously. Various surgical techniques have been used to correct carotid kinking but no particular one has been widely established. We conducted a retrospective review of 18 patients operated upon for internal carotid kinking during the last 5 years, which represents 4.1 per cent of the total carotid procedures performed during the same period. In 13 of the 18 patients carotid endarterectomy was performed before the repair of the kink. In four patients resection of the kinked segment with end-to-end anastomosis was performed combined with longitudinal arteriotomy at the carotid bifurcation. Two patients developed restenosis at the site of anastomosis requiring reoperation with patch angioplasty. Three patients were treated with eversion endarterectomy and end-to-side anastomosis, whereas in six patients we performed resection of the redundant internal carotid artery combined with longitudinal arteriotomy at the bifurcation. The posterior wall was reconstructed with interrupted sutures and the procedure was completed with patch angioplasty of the anterior wall. In four of these cases we used the autogenous resected arterial segment as patch material. None of these patients developed restenosis or symptoms in a follow-up period of 3 to 32 months. In cases in which significant carotid artery stenosis and internal carotid kinking coexist resection of the involved segment with end-to-end anastomosis of the posterior wall and patch angioplasty using the resected autogenous arterial segment constitute a convenient and satisfactory method of reconstruction.

131I-19-iodocholesterol adrenal scans were obtained in seven patients with Cushing's syndrome. Characteristic imaging patterns were seen in three patients with bilateral adrenal hyperplasia with symmetrical uptake of the isotope. Two patients with adrenocortical adenoma and one patient with a well-differentiated adrenocortical carcinoma showed intense activity in one adrenal gland and absent activity in the contralateral gland. In one patient with adrenal nodular hyperplasia asymmetrical uptake was found with increased activity in the right adrenal gland where a larger adenomatous nodule was found at histologic examination. Adrenal imaging with radioactive cholesterol is a useful noninvasive technique for the diagnosis and treatment of Cushing's syndrome.
