Transluminal angioplasty of complete iliac obstructions.

Abstract

Of 64 complete iliac obstructions, 50 (78%) were recanalized using the Gruntzig balloon catheter. Life-table analysis of the patency rate over a 4-year period gives a cumulative success rate of 78%. Only three of eight obstructions that involved both the common and external iliac arteries were successfully dilated. The only serious complication was distal embolization, which occurred in two cases (3.1%). Although the procedure is difficult, with a relatively low technical success rate, the high cumulative patency rate should make it an option in the treatment of all patients with totally occluded iliac artery segments.
