Wandering spleen with splenic arteriovenous torsion
Abstract
Splenic arteriovenous torsion causes splenomegaly and ischemic necrosis of the spleen. The recommended treatment for wandering spleen with hypersplenism is considered to be splenectomy.
1 CASE PRESENTATION
A wandering spleen is a rare condition due to either the absence or laxity of the splenic ligaments. Splenic arteriovenous torsion causes splenomegaly and ischemic necrosis of the spleen. The recommended treatment for wandering spleen with hypersplenism is considered to be splenectomy.
A 35-year-old Japanese woman had been diagnosed with a wandering spleen 20 years ago. No symptoms such as abdominal pain were observed before the delivery of her full-term infant. Contrast-enhanced computed tomography (CE-CT) was conducted post-delivery. The patient's spleen was located in the middle of the abdomen (A). A few months post-delivery, she began to have frequent left-sided abdominal pain. CE-CT showed that her spleen had enlarged and moved into the pelvis (B). There is no dislocation of pancreas. The splenic artery and vein were spirally twisted 1260° (C). A laparoscopic splenectomy was performed (D). No abdominal pain occurred post-surgery. The weight of the removed spleen was 350 g.

This was a rare case of wandering spleen with splenomegaly and abdominal pain due to splenic arteriovenous torsion after childbirth. Wandering spleen which moves from the left hypochondrium to other places in the abdominal cavity had been caused by the absence or laxity of splenorenal and gastrosplenic ligaments.1 Congestion of the splenic vein had thus caused splenomegaly and hypersplenism.1, 2 Abdominal pain developed because of an intermittent blood flow disturbance due to splenic arteriovenous torsion. In wandering spleen with hypersplenism, splenectomy is recommended instead of splenopexy.2
