ABSTRACT
OBJECTIVES:
To assess the outcomes of Cook t-Branch off-the-shelf multibranched stent graft in the treatment of complex aortic aneurysms with narrow internal aortic lumen.METHODS:
Between 2016 and 2020, 48 patients (mean age, 73 years) underwent elective or urgent or emergent Cook t-Branch implantation for thoracoabdominal or para/juxtarenal aortic aneurysms in two Italian vascular centers. Among these, 20 patients presented a paravisceral or pararenal luminal diameter of less than 25 mm. Major clinical and radiologic outcomes of patients with narrow aortic lumen were compared with patients with a larger lumen in a multicenter, nonrandomized, retrospective fashion.RESULTS:
The in-hospital mortality was 10% (5% in the elective setting). Spinal cord ischemia occurred in 6% of the cases. During a mean follow-up of 18 months (range, 1-63 months), late t-Branch procedure-related mortality and the need for reintervention was 0% and 12%, respectively. Comparing the outcomes of patients with large internal aortic lumen (group 1) with patients with small lumen (group 2), no significant difference was found regarding fluoroscopy time (P = .3); technical success (P = 1); early (P = .4) and late (P = 1) mortality; spinal cord ischemia (P = .2); bowel ischemia (P = .5); renal (P = .7), cardiac (P = 1), and respiratory complications (P = 1); reintervention rate (P = 1); and primary patency rate of stented target vessels (P = 1).CONCLUSIONS:
The use of the Cook t-Branch in our experience was safe and effective in the treatment of complex aortic aneurysms regardless the caliber of the aortic lumen. With all the limitations of a small sample size, this approach has demonstrated to be feasible when maneuverability is decreased, with low mortality and morbidity, and acceptable reintervention rates. Perioperative mortality remains closely related to clinical presentation. Large-scale studies are needed to confirm these results.Palabras clave
