The use of thoracic endovascular aneurysm repair (TEVAR) is increasing. Similar to open repair, TEVAR carries a risk of spinal cord ischemia (SCI). We undertook a systematic review to determine whether preoperative cerebrospinal fluid (CSF) drainage reduces SCI. ⋯ Spinal chord injury is uncommon after TEVAR. The role of prophylactic CSF drainage is difficult to establish from the available literature. High-quality studies are required to determine the role of prophylactic CSF drainage in TEVAR.

This study evaluated the risk factors of incomplete thrombosis in the false lumen after thoracic endovascular aortic repair (TEVAR) in patients with extensive acute type B aortic dissection. ⋯ Visceral branches that arose partially or totally from the false lumen, re-entry tears, and maximum diameter of the false lumen on the abdominal aorta were the risk factors of incomplete thrombosis in the false lumen after TEVAR in extensive acute type B dissection.

Thoracic endovascular aortic repair (TEVAR) is known to have a survival benefit over open repair in patients with descending thoracic aneurysms and has become a mainstay of therapy. Because death before 1 year after TEVAR likely indicates an ineffective therapy, we have created a predictive model for death within 1 year using factors available in the preoperative setting. ⋯ Factors are available in the preoperative setting that are predictive of death within 1 year after TEVAR and can guide clinical decision making regarding the timing of repair. Patients with multiple risk factors, such as age ≥ 70 years, coronary artery disease, chronic obstructive pulmonary disease, and a need for an extensive procedure involving adjunctive therapies, have a high predicted mortality within 1 year and may be best served by waiting for a larger aneurysm size to justify the risk of intervention.

Blunt injury to the descending thoracic aorta is a potentially life-threatening condition necessitating rapid assessment and possible surgical intervention. The purpose of this study was to review outcomes of patients who sustained blunt thoracic aortic injury at a single institution. ⋯ Blunt thoracic aortic injury to the descending thoracic aorta is associated with a high overall hospital mortality. Thoracic endovascular aortic repair is associated with significantly lower operative times, procedural blood loss, intraoperative blood transfusion, as well as intraoperative and overall hospital mortality compared with conventional open surgical repair. Consideration of this form of therapy as the initial form of treatment is warranted in anatomically acceptable candidates.

Giant intracranial artery aneurysms (GIAAs) are often not amenable to neurosurgical clipping or endovascular coiling. Extracranial-intracranial (EC-IC) bypass, a procedure that has been essentially abandoned for the treatment of intracranial ischemic disease, followed by parent vessel occlusion, is often successful in treating these aneurysms. Vascular surgeons should be familiar with this operation, especially in centers with neurosurgical capability. ⋯ EC-IC bypass is a safe and effective treatment for GIAAs, with acceptable rates of morbidity (5.6%), mortality (5.6%), and graft patency (89.2%). We suggest that the technique described in this report should be routinely used for treatment of GIAAs in centers where neurosurgery and vascular surgery services are available and should be considered a standard procedure in the armamentarium of the vascular surgeon.
