Splenopneumopexy to Treat Portal Hypertension Produced by Venous Occlusive Disease

Splenopneumopexy is intended to induce collateral circulation between the portal system and the pulmonary veins. It involves performing a parenchymatous anastomosis between the amputated superior pole of the spleen and the exposed pulmonary venous structures in the left lower lobe. This operative procedure was used to treat four patients with extended portal-splenic-mesenteric venous occlusion who did not respond satisfactorily to sclerotherapy. The patients underwent transfemoral embolization of their splenic arteries before splenopneumopexy. Following the operations, all patients have remained well, experiencing cessation of gastrointestinal bleeding for up to 48 months. Splenopneumopexy may be a therapeutic alternative in selected patients with portal hypertension, including those patients with widespread occlusion of the portal vein and its radicles.
