Peripheral ischemia due to retroperitoneal fibrosis.
Two patients with retroperitoneal fibrosis demonstrated symptoms of peripheral vascular ischemia. Arteriolysis to free the distal aorta and iliac vessels was successful in both patients. Aortography in the posteroanterior view was equivocal, but the accompanying urologic abnormalities and a history of methysergide ingestion helped establish the etiology of the ischemia. The most direct approach to the treatment of the vascular obstruction caused by retroperitoneal fibrosis is complete arteriolysis. Most previous reports indicate that it is relatively easy to establish a dissection plane between the fibrotic plaque and the vessel wall. We found that the fibrotic process invaded the vessel wall. Accordingly, the surgeon must anticipate a difficult, tedious dissection when performing arteriolysis for the treatment of vascular compression secondary to retroperitoneal fibrosis.
