Elephant Trunk Procedure

AbstractThe frozen elephant trunk (FET) procedure enables easier replacement of the entire aortic arch because it does not require reaching the distal part of the left subclavian artery (LSCA). However, it requires additional management for reconstruction of the LSCA, which is associated with bleeding events. However, the fenestrated FET technique confers a risk of endoleakage from the fenestration site. We report our unique novel technique in which the proximal side of the hybrid stent graft is cut into V-shape around the subclavian artery and sutured continuously around the orifice of the subclavian artery during aortic stump fixation.

Purpose: To outline the complications encountered after endoluminal treatment in patients with type B aortic dissection. Methods: Between 1999 and 2001, 14 patients (12 men; mean age 60.3 years, range 39–79) with isolated type B aortic dissection (13 chronic, 1 acute) underwent aortic stent-grafting. Three patients with chronic dissection presented an acute clinical picture and were managed emergently. The left subclavian artery was intentionally covered by the prosthesis in 9 patients. Follow-up studies were performed at 6-month intervals. Results: Stent-graft implantation was technically successful in all patients, but incomplete sealing (endoleak) of the entry site required additional proximal stent-graft implantation in 4. The left subclavian artery remained patent in 5 patients. Secondary conversion was required in 3 patients: 2 for acute type A dissection resulting from injury to the aortic arch by Talent endografts and a sustained hemorrhage (left hemothorax). In another patient, a secondary intramural hematoma subsided spontaneously. Anterior spinal artery syndrome in 1 patient persisted at 1 month. No bypass was necessary for the 9 patients with the covered left subclavian arteries. Mean follow-up was 14 months (range 1–23). Conclusions: Stent-grafting is feasible in patients with type B aortic dissection, although it is associated with a considerable rate of complications. Frank reporting of these sequelae for a variety of stent-grafts is of paramount importance to clarifying the limitations of the method.

Abstract OBJECTIVES The goal of this study was to investigate the association between the localization of the distal anastomosis (zone 2/3), the stent graft length (100–160 mm), the position of the distal end of the hybrid prosthesis and the need for secondary aortic intervention (SAI) in acute and chronic thoracic aortic disease after the frozen elephant trunk procedure. METHODS From 2009 through 2020, a total of 232 patients (137 men; mean age, 61.7 ± 13.8 years) were treated with the frozen elephant trunk procedure. The main indications were acute aortic dissection type A (n = 106, 46%), chronic aortic dissection type A (n = 52, 22%) and degenerative thoracic aortic aneurysm (n = 74, 32%). RESULTS The rate of SAI was significantly higher when we performed a distal anastomosis in zone 2 rather than in zone 3, whereas the rate of SAI was less frequent if the distal positioning of the hybrid prosthesis was below TH 4–5. Combining the zone 2 concept and the short stent graft length (100 mm) was associated with a significantly higher rate of SAIs. Patients with a distal anastomosis in zone 2 were significantly less likely to have a recurrent laryngeal nerve injury (P < 0.001). However, no association between a specific arch zone of a distal anastomosis and the occurrence of spinal cord injury was observed. CONCLUSIONS Rates of SAIs are highest in patients who were treated with a distal anastomosis in zone 2 and a short stent graft (100 mm) with the distal end of the hybrid prosthesis at vertebral level TH 2–3.

Abstract OBJECTIVES Aortic dissection (AoD) in the presence of an aberrant right subclavian artery (ARSA) is very rare. Clinical experience is limited, and there is no consensus regarding the optimal management strategy. We seek to evaluate the safety and efficacy of the total arch replacement (TAR) and frozen elephant trunk (FET) technique as an approach to AoD in patients with ARSA by retrospectively analysing our single-centre experience. METHODS From 2009 to 2017, we performed TAR + FET for 22 patients with ARSA sustaining AoD (13 acute, 59.1%). The mean age was 46.0 years [standard deviation (SD) 8.3], and 19 patients were male (86.4%). ARSA orifice was dilated in 15 (68.2%) patients, and a Kommerall diverticulum was diagnosed in 13 (59.1%) patients with a mean diameter of 21.8 mm (SD 7.7; range 15–40). Surgery was performed via femoral and right/left carotid cannulation under hypothermic circulatory arrest at 25°C. The ARSA was reconstructed using a separate branched graft. RESULTS ARSA was closed proximally by ligation in 16 (72.7%) patients, direct suture in 4 (18.2%) patients and both in 2 (9.1%) patients. Operative mortality was 13.6% (3/22). Type Ib endoleak occurred in 1 (4.5%) patient at 8 days. Follow-up was complete in 100% at mean 4.2 years (SD 2.0), during which 3 late deaths and 1 reintervention for type II endoleak occurred. Survival was 81.8% and 76.4% at 3 and 5 years, respectively. Freedom from reoperation was 89.2% up to 8 years. In competing risks analysis, the incidence was 22.1% for death, 10.8% for reoperation and 67.1% for event-free survival at 5 years. The false lumen, ARSA orifice and Kommerall diverticulum were obliterated in 100%. Grafts were patent in 100%. No patients experienced cerebral ischaemia and upper extremity claudication. Hypothermic circulatory arrest time (min) was sole predictor for death and aortic reintervention (hazard ratio 1.168, 95% confidence interval 1.011–1.348; P = 0.034). CONCLUSIONS The TAR and FET technique is a safe and efficacious approach to AoD in patients with ARSA. Modifications of routine TAR + FET techniques are essential to successful repair, including femoral and right/left carotid artery cannulation, ligation of ARSA on the right side of the trachea and ARSA reconstruction with a separate graft.
