Abstract

Isolated left-sided portal hypertension is a rare clinical syndrome caused by splenic veno-occlusive disease. Splenic vein thrombosis and extrinsic compression causes proximal splenic vein hypertension, and the splenic blood flows into the superior mesenteric or portal vein through the upper stomach's collateral vessels, such as the short gastric, coronary, and gastroepiploic veins. Open splenectomy is recommended to treat gastrointestinal bleeding caused by isolated left-sided portal hypertension. Interventional management could be a clinically useful option for selected patients who want to avoid surgical corrections. The report presents two cases of left-sided portal hypertension with gastric variceal bleeding.

좌측 단독 문맥고혈압은 비장 정맥이 폐쇄되어 생기는 드문 임상 질환이다. 비장 정맥의 혈전증 혹은 외부 압박으로 인해 근위부 비장정맥의 고혈압이 발생하게 되며, 비장의 혈류는 짧은 위 정맥, 관상정맥, 위대망정맥 같은 측부혈관을 통하여 상장간막 정맥 혹은 문맥으로 흘러가게 된다. 위장관 출혈을 유발하는 좌측 단독 문맥고혈압에는 개복 비장절제술이 첫 번째 치료방법으로 추천된다. 하지만 중재시술을 통한 치료가 수술적 교정을 원치 않는 환자들에게는 임상적으로 유용한 치료 선택지가 될 수 있다. 본문에서는 위정맥류 출혈을 가진 좌측 문맥 고혈압에 대한 두 개의 증례를 다루고자 한다.
