Variceal bleeding due to intrahepatic arterioportal fistula is an unusual complication of percutaneous liver biopsy. As majority of variceal bleeding are cirrhotic in origin, the rare occurrence of an acquired intrahepatic arterioportal fistula presents a therapeutic dilemma.
We report the case of a 57-year-old female with refractory variceal bleeding that occurred six years after a percutaneous liver biopsy. As part of the workup for placement of Transjugular Intrahepatic Portosystemic Shunt, a computed tomography hepatic arteriography was performed. This revealed a large arterioportal fistula in left lobe of liver. Variceal bleeding was controlled following successful embolisation of the arterioportal fistula.
Persistent intrahepatic arterioportal fistula can result in portal hypertension and variceal bleeding. This is a rare complication of percutaneous liver biopsy that warrants consideration as an aetiology of portal hypertension with variceal bleeding. The therapeutic strategy for refractory bleeding due to intrahepatic arterioportal fistula is different from cirrhotic portal hypertension and requires trans-arterial embolisation of the fistula.
This case highlights the need to consider arterioportal fistula as an aetiology of portal hypertension as therapeutic strategy in refractory variceal bleeding is different from cirrhotic portal hypertension.
肝内动脉门静脉瘘导致的静脉曲张出血是经皮肝穿刺活检的一种罕见并发症。由于大多数静脉曲张出血源于肝硬化,后天性肝内动脉门静脉瘘的罕见发生带来了治疗难题。
我们报告一例57岁女性患者,在经皮肝穿刺活检六年后出现难治性静脉曲张出血。作为经颈静脉肝内门体分流术置入检查的一部分,进行了肝脏计算机断层血管造影。结果显示肝脏左叶存在一个大的动脉门静脉瘘。在成功栓塞动脉门静脉瘘后,静脉曲张出血得到控制。
持续性肝内动脉门静脉瘘可导致门静脉高压和静脉曲张出血。这是经皮肝穿刺活检的一种罕见并发症,应被视为门静脉高压伴静脉曲张出血的病因之一。肝内动脉门静脉瘘所致难治性出血的治疗策略与肝硬化门静脉高压不同,需要对瘘进行经动脉栓塞。
本病例强调了需将动脉门静脉瘘视为门静脉高压的病因,因为难治性静脉曲张出血的治疗策略与肝硬化门静脉高压不同。
