Abstract

Abdominal aortic thrombosis is a rare entity in neonates and has mostly been associated with umbilical artery or cardiac catheterization. We present a complicated case of an otherwise healthy neonate who developed thrombosis of abdominal aorta with renal failure. Therapy with intravenous heparin was unsuccessful, and thrombolysis was contraindicated because of disseminated intravascular coagulation so we decided to perform open thrombectomy using the left retroperitoneal approach. The following day, thrombosis recurred in the same extent and despite high risk of bleeding Alteplase was eventually given, which resulted in recanalization of the aorta 6 hours later. Renal function recovered, dialysis was discontinued, and further course was uneventful. The treatment of abdominal aortic thrombosis in neonates should be considered on a case-by-case basis because the available data on the condition are limited to case report and series. If open thrombectomy is performed, retroperitoneal approach should be preferred because it allows for easy institution of peritoneal dialysis should the need arise.
