Elephant Trunk Procedure

Background: In this study, we present our mid-term results of reoperation with the frozen elephant trunk procedure due to patent false lumen-related complications in patients previously undergoing supracoronary aortic repair for acute type A aortic dissection. Methods: Between January 2013 and September 2018, a total of 23 patients (17 males, 6 females; mean age 51.5±9.7 years; range, 30 to 67 years) who underwent ascending aortic replacement due to type A aortic dissection and, later, frozen elephant trunk procedure for residual distal dissection were included. For diagnostic purposes and follow-up, computed tomography angiography was performed in all patients, and both re-entry and aortic diameters were evaluated. Echocardiography was used to evaluate cardiac function and valve pathologies. Results: The Ishimaru zone 0 (n=11, 47.8%), Ishimaru zone 1 (n=1, 4.3%), Ishimaru zone 2 (n=4, 17.4%), and Ishimaru zone 3 (n=7, 30.4%) were used for frozen elephant trunk stent graft fixation. The mean duration of cardiopulmonary bypass and antegrade selective cerebral perfusion was 223.9±71.2 min and 88.9±60.3 min, respectively. In-hospital mortality was 13%, while there was one (4.3%) aortic-related death and four (17.4%) re-interventions during follow-up. Conclusion: Early repair should be considered in the presence of persistent dissections due to alarmingly high mortality rates of reoperations. Reoperation with the frozen elephant trunk procedure has acceptable results and the decision of the procedure to be performed should be based on preoperative risk factors of the patient.

A 65-year-old man with chronic type A aortic dissection underwent zone 1 debranching and frozen elephant trunk with whole-body perfusion. This approach has the potential to improve technical feasibility of the frozen elephant trunk procedure and reduce its ischemic complications.

Abstract We report a case of a 51-year-old male with complicated acute type A aortic dissection who initially underwent a supracoronary and aortic arch replacement using frozen elephant trunk technique. False-lumen perfusion was revealed later which resulted in the collapse of the true lumen. Endovascular fenestration of the dissection flap was performed. True-lumen reperfusion with false-lumen regression was achieved. Endovascular fenestration using a re-entry catheter represents an efficient and safe treatment approach for this rare but serious complication.

Abstract OBJECTIVES Our goal was to determine the early and midterm outcomes after total arch replacement with the frozen elephant trunk (FET) technique compared to those of the conventional elephant trunk (ET) technique for acute retrograde type A aortic dissection. METHODS Between 2012 and 2019, a total of 49 patients had total arch replacement for acute retrograde type A aortic dissection. Patients were divided into the conventional ET (n = 17) and FET (n = 32) groups. The false lumen status was evaluated using enhanced computed tomography (CT) 1 week postoperatively. The diameter of the downstream aorta was evaluated annually using CT. The median follow-up period was 29 months. RESULTS Preoperative data and neurological complications were not significantly different in the 2 groups. The diameter and length of the ET prosthesis were significantly larger and longer in the FET group. The overall early mortality rate was 10.2% (5/49) with no differences between the 2 groups. The mean follow-up period was significantly longer in the conventional ET group. The rates of freedom from aortic events at 3 years were significantly lower in the FET group. At the level of the distal arch, postoperative false lumen patency was significantly lower and the follow-up aortic diameter was significantly smaller in the FET group. CONCLUSIONS The FET technique facilitates false lumen thrombosis and aortic remodelling at the distal arch level, with fewer adverse aortic events during the follow-up period with acceptable early outcomes; however, these findings are exploratory and require investigation.

OBJECTIVES: The frozen elephant trunk (FET) technique has become an important tool in the treatment of acute type A aortic dissection. The aim of this study was to evaluate the effect of long FET on spinal cord injury (SCI) and distal aortic remodeling after acute type A aortic dissection based on clinical and radiological outcomes. METHODS: From January 2018 to November 2019, 158 patients [mean age 51.8 years (range 32 - 78 years), 88.6% male] with acute type A aortic dissection were treated by FET with 100 mm (n=113) or 150 mm (n=45) open hybrid stent graft prosthesis. Patients were divided into two groups according to the length of FET. The clinical and radiological outcomes of the patients were reviewed retrospectively. RESULTS: Postoperative outcomes did not differ significantly: in-hospital mortality (9.7% vs 6.7%, P=0.758) and SCI (5.3% vs 2.2%, P=0.674). Aortic remodeling, which was evaluated by aortic diameter, true lumen diameter, false lumen diameter and the rate of false lumen complete thrombosis, was more positive in long FET group in the descending thoracic aorta during the follow-up period. At the abdominal level, there was no statistically significant difference between the two groups. CONCLUSIONS: The long version of FET does not increase the risk of SCI in patients with acute type A aortic dissection. The application of long FET can achieve better results in terms of remodeling of the thoracic aorta in the short- and medium-term follow-up.
