In thoracic endovascular aortic repair (TEVAR), covering the celiac artery (CA) is sometimes necessary to secure the distal seal. We report the outcomes of planned CA coverage in our experience with TEVAR.
This study clearly depicts that Cases requiring CA coverage during TEVAR from October 2008 to September 2018 were retrospectively reviewed. Patient demographics, indications for CA coverage, communication between the CA and the superior mesenteric artery (SMA), concomitant CA embolization, and perioperative and late results were collected in a prospective database and analyzed. During the study decade, 357 patients underwent TEVAR at our institution. Of these patients, 15 (4.2%) required CA coverage. All 15 patients were male, and the mean age was 72.8 years (range, 44-80 years). The mean aneurysm size was 67.5 mm (range, 50-82 mm). The etiologies included 10 degenerative aneurysms (66.7%; 2 ruptures [13.3%], 4 dissecting aneurysms [26.7%], and 1 case of type IB endoleak [6.7%]) after TEVAR. Our study demonstrates the safety and efficacy of CA coverage in facilitating adequate distal sealing in selected patients undergoing TEVAR. Because the distal sealing length is not completely sufficient in most cases requiring CA coverage, the long-term efficacy of CA coverage during TEVAR should be determined in a large prospective study.
