In situ laser fenestration of aortic septum to bridge false and true lumen during endovascular repair of aortic dissection.

ABSTRACT: Fenestration of the septum between the true and false lumen might be necessary after aortic dissection. We report the technical aspects of in situ laser fenestration of the aortic dissection septum. Two illustrative cases are provided: a 56-year-old man with false lumen deployment of a frozen elephant trunk graft, and a 67-year-old man who underwent fenestrated endovascular aortic repair with a target branch vessel off the false lumen. In both cases, the septum was crossed using in situ laser fenestration. This technique is a precise option to enable passage between true and false lumens during endovascular repair of an aortic dissection.

Project description:ObjectiveThe study objective was to evaluate the management of malperfusion in acute type B aortic dissection with endovascular fenestration/stenting.MethodsFrom 1996 to 2018, 182 patients with an acute type B aortic dissection underwent fenestration/stenting for suspected malperfusion based on imaging, clinical manifestations, and laboratory findings. Data were obtained from medical record review and the National Death Index database.ResultsThe median age of patients was 55 years. Signs of malperfusion included abdominal pain (61%), lower-extremity weakness (27%), nonpalpable lower-extremity pulses (24%), and abnormal lactate, creatinine, liver enzymes, and creatine kinase levels. Confirmed hemodynamically significant malperfusion affected the spinal cord (2.7%), celiac (24%), superior mesenteric (40%), renal (51%), and iliofemoral (43%) arterial distributions. Of the 182 patients, 99 (54%) underwent aortic fenestration/stenting, 108 (59%) had 1 or multi-branch vessel fenestration/stenting, 5 (2.7%) had concomitant thoracic endovascular aortic repair, 17 (9.3%) had additional thrombolysis or thromboembolectomy, and 48 (26%) received no intervention. After fenestration/stenting, 24 patients (13%) required additional procedures for necrotic bowel or limb and 9 patients (4.9%) had subsequent aortic repair (thoracic endovascular aortic repair, open repair) before discharge. The new-onset paraplegia was 0%. The in-hospital mortality was 7.7% over 20+ years and 0% in the last 8 years. The 5- and 10-year survivals were 72% and 49%, respectively. The significant risk factors for late mortality were age and acute paralysis (hazard ratio, 3.5; both P < .0001). Given death as a competing factor, the 5- and 10-year cumulative incidence of reintervention was 21% and 31% for distal aortic pathology, respectively.ConclusionsPatients with acute type B aortic dissection with malperfusion can be managed with endovascular fenestration/stenting with excellent short- and long-term outcomes. This approach is particularly helpful to patients with static malperfusion of aortic branch vessels.
