ABSTRACT
BACKGROUND:
In patients with abdominal aortic aneurysms, 10-20% has concomitant thoracic aortic pathologies. These are typically managed with staged endovascular aneurysm repair (EVAR) and thoracic endovascular aortic repair (TEVAR) due to a perceived higher risk of spinal cord ischemia from a simultaneous intervention. We aimed to determine the outcomes of patients undergoing simultaneous EVAR and TEVAR for concomitant aneurysms.METHODS:
A retrospective cohort study was performed using the Vascular Quality Initiative registry from December 2003 to January 2021. Patients undergoing same day EVAR and TEVAR were included and analyzed in accordance with the Society for Vascular Surgery reporting standards. Primary outcomes were technical success and spinal cord ischemia.RESULTS:
Simultaneous EVAR and TEVAR were performed in 25 patients. Median age was 75.0 (interquartile range [IQR], 63.0-79.0) years and 20 (80.0%) patients were male. Two (4.0%) patients were symptomatic and 4 (16.0%) presented with rupture. Median maximum infrarenal and thoracic aortic diameter was 57.0 (IQR, 52.0-65.0). Infrarenal aortic neck length was 15.0 mm (IQR, 10.0-25.0), and diameter was 27.0 mm (IQR, 24.5-30.0). Median procedure time was 185.0 min (IQR, 117.8-251.3), fluoroscopy time 32.7 min (IQR, 21.8-63.1), and contrast volume 165 mL (IQR, 115.0-207.0). There were 3 (12.0%) Type Ia endoleaks and 3 (12.0%) Type II endoleaks in EVAR's, with 1 (4.0%) Type Ia and 1 (4.0%) Type II endoleak in TEVARs. In-hospital mortality occurred in 3 (12.0%) patients (1 elective, 2 ruptures). Spinal cord ischemia occurred in 1 (4.0%) patient. This patient had a symptomatic aneurysm. Thoracic coverage extended from Zone 4 to Zone 5 and an emergent spinal drain was placed postoperatively. Symptoms were present on discharge. There was 1 (4.0%) conversion to open repair which occurred in a ruptured aneurysm. Technical success was achieved in 19 (76.0%) patients, however when excluding ruptured aneurysms, was achieved in 17 (81.0%) patients. Follow-up data was available for 19 (76.0%) patients at a median of 426.0 (IQR, 329.0-592.5) days postoperatively. A total of 3 (12.0%) patients died during the late mortality period, at a mean of 509.0 (±503.7) days. Median change in abdominal and thoracic aortic sac diameter was -1.35 mm (IQR, -11.5 to 2.5) and 8.0 (IQR, -10.5 to 12.0), respectively.CONCLUSIONS:
Simultaneous EVAR and TEVAR for concomitant abdominal and thoracic aortic aneurysms can be performed with low rates of spinal cord ischemia. Short- and mid-term outcomes are acceptable.
