Mid-term results of zone 0 thoracic endovascular aneurysm repair after ascending aorta wrapping and supra-aortic debranching in high-risk patients. Interactive Cardiovascular and Thoracic Surgery, 24(6):882-889.

Abstract

OBJECTIVES: Surgical repair of aneurysmal disease involving the ascending aorta, aortic arch and eventually the descending aorta is generally associated with significant morbidity and mortality. A less invasive approach with the ascending wrapping technique (WT), supra-aortic vessel debranching (SADB) and thoracic endovascular aneurysm repair (TEVAR) in zone 0 was developed to reduce the associated risk in these patients.
METHODS: During a 10-year period, consecutive patients treated by the ascending WT, SADB and TEVAR in zone 0 were included. All patients were considered at high risk for conventional surgery. Measured outcomes included perioperative deaths and morbidity, maximal aortic transverse diameter (TD) and its postoperative evolution, endoleak, survival, freedom from cardiovascular reinterventions, SADB freedom from occlusion and aortic valve function during follow-up. Median follow-up was 37.4 [mean = 34; range, 0-65; standard deviation (SD) = 20] months.
RESULTS: Twenty-six cases were included with a mean age of 71.88 ( r  = 56-87; SD = 8) years. A mean of 2.9 supra-aortic vessels (75) per patient was debranched from the ascending aorta. The mean time interval from WT/SADB and TEVAR was 29 ( r  = 0-204; SD = 48) days. TEVAR was associated with chimney and/or periscope grafts in 6 (23%) patients, and extra-anatomical supra-aortic bypasses were performed in 6 (23%) patients. Perioperative mortality was 7.7% (2/26). Neurological events were registered in 3 (11.5%) cases, and a reintervention was required in 3 (11.5%) cases. After the WT, the ascending diameter remained stable during the follow-up period in all cases. At mean follow-up, significant shrinkage of the arch/descending aorta diameter was observed. A type I/III endoleak occurred in 3 cases. At 5 years, the rates of survival, freedom from cardiovascular reinterventions and SADB freedom from occlusion were 71.7, 82.3 and 96%, respectively.
CONCLUSIONS: The use of the ascending WT, SADB and TEVAR in selected patients with complex thoracic aorta disease is safe and shows promising mid-term results at 3 years. The combination of these techniques could represent an alternative to the standard open surgical repair, especially in older patients or in patients unfit for cardiopulmonary bypass.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
