Transcatheter arterial embolization in gastric cancer patients with acute bleeding.
The safety and clinical effectiveness of transcatheter arterial embolization for bleeding associated with unresectable gastric cancer was evaluated. Twenty-three patients with bleeding from unresectable gastric cancer underwent transcatheter arterial embolization. Of the 23 patients, eight showed signs of active bleeding, such as contrast extravasation or pseudoaneurysm, seven showed only tumor staining, and the remaining eight patients showed negative angiographic findings. All embolization procedures were successful without procedure-related complications. In all eight active bleeding patients, immediate hemostasis was achieved. The overall clinical success rate was 52% (12/23). Recurrent bleeding within 1 month occurred in one (8%) in 12 patients with initial clinical success. One patient showed partial splenic infarction after embolization of the splenic artery for active bleeding from the short gastric artery. Overall 30-day mortality rate was 43% (10/23). The median overall survival period was 38 days. In patients with bleeding from unresectable gastric cancer, transcatheter arterial embolization was found to be safe and effective for achieving immediate hemostasis for active bleeding. Although the clinical success rate was not high, the recurrent bleeding rate was low at 1 month post procedure.
