Portal Vein Thrombosis After a Right Hemicolectomy: A Case Report

Abstract

The patient, a 43-year-old male, underwent uneventful laparoscopic right-sided hemicolectomy for a benign polyp, too large to be removed by colonoscopy. His postoperative course was uneventful; however, he returned 16 days after discharge with vague abdominal pain. A CT scan of his abdomen and pelvis showed extensive acute thrombus in portal, superior mesenteric, and splenic veins. After initial intravenous anticoagu- lation, follow-up imaging showed a persistent clot. The patient then underwent catheter-guided portal vein thrombolysis with tissue plasminogen activator (tPA), on postoperative day 29. He was doing well on 12-month follow-up. Portomesenteric thrombosis is a rare complication of laparoscopic surgery. It can occur even in the absence of any direct vascular trauma, as well as in delayed fashion after an initially uneventful procedure. Gold standard for treatment has not been developed and remains individualized based on the extent ofthe thrombus, the patient's clinical status, and condition of the affected bowel.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
