Gastric coronary vein to portal vein reconstruction in liver transplant: case report.

OBJECTIVES

Portal vein thrombosis is a common complication in end-stage liver diseases of candidates for liver transplant. Most portal vein thromboses can be removed with thrombectomy. However, if the thrombosis extends to the distal superior mesenteric vein, it is difficult to reconstruct the portal vein. We report herein a case of dilated gastric coronary vein to portal vein reconstruction in liver transplant.

CASE REPORT: During the operation, the portal vein thrombosis was confirmed; it extended to the distal superior mesenteric vein. It could not be removed, and a jumping graft vein could not be used either. The dilated gastric coronary vein was dissected. After a piggy-back caval anastomosis, the recipient gastric coronary vein was anastomosed to donor portal vein using side-to-end anastomosis. Successive ultrasound studies demonstrated patent portal anastomosis. At postoperative day 30, computed tomography scans confirmed the patency of the portal anastomosis. The patient recovered fully and at the time of this writing, was doing well 1 year after transplant. Neither ascites nor upper gastrointestinal bleeding occurred.

CONCLUSIONS

If complete portal vein thrombosis extends to the distal superior mesenteric vein, and a jumping graft vein cannot be applied, the recipient gastric coronary vein or other collateral varix anastomosed to the donor portal vein is an alternative.
