Takayasu's arteritis: the middle aortic syndrome.

An isolated, long segment abdominal aortic coarctation is an infrequent occurrence. Although different names have been given to this entity, it is believed that all represent different stages of nonspecific inflammatory arteritis, or Takayasu's disease. Usually involving the arch and descending aorta, occasionally an isolated segment of the abdominal aorta is involved. Morbid presentation reflects the involvement with narrowing of visceral branches and aortic occlusive disease, as illustrated in this case. Operative intervention with aortic bypass and visceral revascularization is the treatment of choice for recurrent or extensive aortic involvement.

Lumbar sympathectomy: a place in clinical medicine.

Currently lumbar sympathectomies are infrequently performed because the effectiveness of the procedure is unclear. The previous indication of limb-threatening ischemia has been usurped by distal arterial reconstruction. Some vascular surgeons feel there is no remaining clinical role. This paper suggests four categories of patients, represented by five case reports, where lumbar sympathectomy may prove beneficial: 1) Hypertensive patients with painful leg ulcers; 2) Toe and foot amputations in which arterial reconstruction is not feasible; 3) Posttraumatic causalgia (sympathetic dystrophy); 4) As an adjunct to distal graft bypass.

Visceral neoplasia presenting at the umbilicus.

An umbilical mass as the presenting and only symptom of an underlying visceral carcinoma is an infrequent occurrence. The implications of such a finding are illustrated by four examples, with primary tumors in pancreas, colon, and ovary. Adenocarcinoma in the umbilicus represents a metastatic deposit until proved otherwise. Further diagnostic evaluation to localize the primary tumor should be based upon therapeutic implications. The need for abdominal exploration must be individualized.
