Ischemic damage to the spinal cord following surgery of the abdominal aorta.

Ischemic damage to the spinal cord after reconstructive procedures of the abdominal aorta is a rare complication. The literature up to and including 1980 records 46 of these cases. In this paper we present four additional cases and discuss the etiological factors and the practical measures available to minimize the risk of this unpredictable complication.

Ischiadic nerve entrapment by an extra- and intrapelvic lipoma: a rare cause of sciatica.

A 60-year-old woman had persistent left-sided ischialgia. After several years, a left-sided subgluteal mass extended to the pelvis. Computed tomography (CT) disclosed a large subgluteal and intrapelvic lipoma. Symptoms were relieved by excision of the tumor.
