Clinical case of successful endovascular treatment of the false aneurysm of truncus coeliacus with the formation of an arteriovenous fistula after pancreatoduodenal resection

False postoperative visceral aneurysms are extremely rare in the clinical practice. Often false aneurysms are a diagnostic finding, and after discharge from the hospital, the patient is exposed to an extreme risk of rupture and death. We present our own observation of successful verification and endovascular correction of pseudoaneurysm of truncus coeliacus after surgical treatment of cancer of the distal part of the common bile duct.
