It can be complicated by type B aortic dissection (TBAD) or aneurysmal formation at its ostium. Recently, hybrid repair with thoracic endovascular aortic repair (TEVAR) has appeared to be more favorable. Due to the normal anatomic proximity of the ARSA to the left subclavian artery (LSA) orifice in KD, coverage of the bilateral subclavian arteries (SCAs) to obtain an adequate proximal landing zone (PLZ) is usually required, and double cervicotomy for SCA revascularization potentially increases the risk of complications. Technique: This technique was demonstrated on a 50-year-old man presenting with progressive aneurysmal formation of KD with ARSA after chronic TBAD. A 3-step technique, namely left cervical debranching with a left common carotid artery to LSA bypass graft, TEVAR, and an LSA-to-ARSA endovascular debranching with a self-expanding covered stent by a through-and-through wire from the right brachial artery to the bypass graft, was performed in a 1-stage repair to cover the primary tear of TBAD and preserve the bilateral SCAs. The postoperative course was uneventful. Conclusion: This technique can prevent complications from double cervicotomy and achieve an adequate PLZ with preservation of the bilateral SCAs for TEVAR. © The Author(s) 2021. |
