[Endoscopic variceal ligation and percutaneous transhepatic obliteration difficulty in esophageal variceal bleeding: a case report].

A 48-year-old male patient with a history of alcoholic cirrhosis was admitted to our hospital due to hematemesis with a 7-day history of melena. Emergency esophagogastroduodenoscopy revealed esophageal variceal bleeding. We attempted hemostasis with endoscopic variceal ligation (EVL). The esophageal mucosa was not aspirated into the EVL device although the patient had no history of endoscopic injection sclerotherapy or EVL. Percutaneous transhepatic obliteration (PTO) was performed and esophageal variceal bleeding was successfully hemostasis. PTO is a viable option for refractory esophageal bleeding.

[A case of refractory ascites due to splenic arteriovenous fistula appeared during the course of observation and cured by embolization therapy].

This is a case of a 61-year-old female who presented to our hospital with liver dysfunction without any symptoms. She was diagnosed with splenic arteriovenous fistula. About 8 months later, she visited the hospital again due to abdominal distention and diarrhea. Computerized tomography (CT) revealed splenic aneurysm, dilated splenic vein enhanced in the arterial phase, ascites, and intestinal edema. We considered that these findings were caused by portal hypertension due to splenic arteriovenous fistula. The splenic aneurysm was managed with coil embolization. Completion arteriography revealed the absence of flow into the splenic arteriovenous fistula. Surveillance CT scans at 2 months post-procedure confirmed complete occlusion of the aneurysm and arteriovenous fistula. There was no evidence of splenic infarction. The patient remained asymptomatic 1 year post-procedure. Asymptomatic splenic arteriovenous fistula is rare and needs immediate treatment due to the high probability of deterioration.
