REPAIR OF MULTIPLE MYCOTIC AORTIC-ANEURYSMS IN A NEWBORN

Thoracoabdominal aortic and common and internal iliac artery mycotic aneurysms resulted from an umbilical arterial catheter in a 3 1 2-week-old boy. He underwent staged repair including an 8-mm Gore-tex tube graft, primary repair of the common iliac artery aneurysm, and resection of the internal iliac aneurysm. His operative and postoperative course was uneventful. He was asymptomatic at 17 months' follow-up, with equal blood pressure in the upper and lower extremities. Magnetic resonance imaging showed no stenoses or recurrent aneurysms at the anastomotic sites of the Gore-tex tube graft. Blood supply to his left leg came from collaterals, principally a large crossing vessel from the right iliac artery. This case represents the first successful aortic replacement in a 5 week old with extensive involvement of the thoracoabdominal aorta and its branch vessels. © 1993.
