title: Celiac trunk embolization, as a means of elongating short distal descending thoracic aortic aneurysm necks, prior to endovascular aortic repair.
abstract: The purpose of this study was to report our experience in elongating short distal necks of descending thoracic aortic aneurysms (DTAAs) by coil embolization of the celiac trunk prior to endovascular aneurysm repair (EVAR). During 6 years seven patients (five men and two women; mean age, 74) who had DTAAs with short distal necks unsuitable for conventional EVAR, and well patent superior and inferior mesenteric arteries based on CT, were treated in one session with EVAR after the celiac trunk was coil embolized to elongate the neck. All patients were followed by CT every 3 months in the first year and every 6 months thereafter. Technical success was achieved in all patients, and no early or late ischemic complications were noted. No procedural complications occurred and good aneurysm sealing was obtained in all patients. Three endoleaks were identified after 3 months (one patient) and 6 months (two patients); all were treated successfully with insertion of an additional stent-graft. In patients with DTAAs who are candidates for EVAR but have short aneurysm distal necks, celiac trunk embolization -- only if the superior and inferior mesenteric arteries are patent -- is a good and safe way to elongate the neck and enable EVAR.
