Outcomes following distal bypass graft occlusion in diabetics.

The objectives of this study were to define clinical outcomes following distal bypass graft occlusion in diabetic patients and identify factors predictive of limb loss. A retrospective review was conducted of all distal graft occlusions over a 5-year period in diabetic patients. Popliteal grafts, perioperative (30 days) failures, and redo distal bypasses were excluded.

Peripheral vasoconstriction in patients with sleep related periodic leg movements.

Two patients complaining of insomnia had sleep-related periodic leg movements (nocturnal myoclonus) on polysomnographic evaluation. Both also complained of cold feet and had abnormal peripheral pulse examinations. Treatment with phenoxybenzamine, alpha-adrenergic blocker, normalized the peripheral pulse responses, reduced the complaint of insomnia, and reduced the sleep related leg movements but resulted in only mild sleep improvements.

Noninvasive device to produce and maintain an erection-like state.

In 35 men with organic impotence we have tested a noninvasive device which uses a vacuum to produce an erection-like state and rubber bands to maintain this state. The subjects were first evaluated to determine the cause of their impotence and to establish that it had an organic basis. Using this device 32 of the 35 subjects achieved penile rigidity sufficient for vaginal penetration.

Femoral intraarterial digital angiography: an outpatient procedure.

Selective intraarterial digital angiography was performed in 50 patients with known or suspected peripheral vascular disease. Excellent anatomic detail was provided by low-volume injection of 80 mgl/ml contrast medium. The procedure was performed with a 20- to 21-gauge needle or short 3 French catheter as an outpatient procedure.

Diagnosis of mycotic abdominal aortic aneurysm using 67-gallium citrate.

Mycotic aneurysms of the abdominal aorta are uncommon, but potentially lethal problems. Clinical subtleties may suggest their presence, but in the past, definitive diagnosis has been dependent on surgical exploration or autopsy findings. A case is presented in which 67-gallium citrate abdominal scanning localized the site of sepsis in an abdominal aortic aneurysm and allowed for prompt and successful surgical therapy.
