Vascular anomalies and interventions

Pseudoaneurysms develop as a result of inflammation, trauma, neoplasm, or surgical procedures. Because rupture of a pseudoaneurysm can cause massive life-threatening hemorrhage, prompt and definitive treatment is required. The conventional treatment has been surgical ligation or resection of the aneurysm with or without partial resection of the involved end organ, but transcatheter embolization has a high success rate, with lower morbidity and mortality rates than surgery, and is generally considered the current treatment method of choice ( 1 Ikeda O. Nakasone Y. Tamura Y. Yamashita Y. Endovascular management of visceral artery pseudoaneurysms: transcatheter coil embolization using the isolation technique. Cardiovasc Intervent Radiol. 2010; 33: 1128-1134 Crossref PubMed Scopus (46) Google Scholar ). However, access to the pseudoaneurysm is a prerequisite to achieving successful embolization, and is sometimes very difficult. We present a case of a hepatic hilar pseudoaneurysm fed by tortuous collateral vessels that was considered to be unsuited for standard antegrade transarterial treatment and was successfully treated via a transhepatic arterial approach. Institutional review board approval was not required for this case report.
