BACKGROUND: We investigated the safety and efficacy of physician-modified thoracic endovascular aortic repair using a low-profile device for aortic arch lesions.
METHODS: A total of 42 consecutive patients (mean age 67.2 ± 12.7 years; 32 men) with aortic arch lesions were treated by physician-modified thoracic endovascular aortic repair using a low-profile device (Zenith Alpha Thoracic Endovascular Graft) with four scallops or 13 fenestrations for the common carotid artery and 38 fenestrations or 30 branches for the left subclavian artery. The aortic repair indications were acute type B aortic dissection (n = 17, 40.5%), degenerative aneurysm (n = 14, 33.3%), chronic dissection aneurysmal degeneration (n = 4, 9.5%), and ulcer-like projection (n = 2, 4.8%). The mean iliac artery diameter was 7.6 ± 1.1 mm.
RESULTS: There were no branches covered unintentionally or patients who died and suffered from severe spinal cord ischemia perioperatively. One patient (2.4%) experienced a postoperative minor stroke with full neurological recovery. The mean follow-up time was 18 ± 11 months, with 28 patients (66.7%) having at least 12 months. One access-related complication (2.4%) occurred. Two residual Ia (4.8%) and three residual IIIa (7.1%) endoleaks were treated by reintervention. There were no open repair conversions, ruptures, or other aortic complications.
CONCLUSION: Physician-modified thoracic endovascular aortic repair using the low-profile device may be a safe, feasible, and time-saving method for preserving the cervical artery and has high reproducibility and anatomical reconstruction. However, its durability requires long-term follow-up.
