Abstract
OBJECTIVE: To report the outcome of elective fenestrated and branch (FEVAR-BEVAR) endovascular aortic repair with supracoeliac (SC) sealing zones and the impact of staged repair without prophylactic cerebrospinal fluid (CSF) drainage on the incidence of spinal cord ischaemia (SCI).
METHODS: Two hundred and seventy consecutive patients (217 men; mean [SD] age, 72.8 ± 6.3 years; median (IQR) diameter 65 mm [62-75 mm]) with juxtarenal (JRAAA) (n = 69) or thoraco-abdominal aortic aneurysms (TAAAs) (n = 201) underwent elective FEVAR (n = 192) or BEVAR (n = 78) with renovisceral stent grafting, proximal SC (Zones 1-5; <40 mm [n = 83]; ≥40 mm [n = 187]) and distal infrarenal aorto-iliac sealing zone (Zones 9-11) between December 2008 and September 2017. A spinal cord protection protocol (SCPP) including staging without prophylactic CSF drainage was introduced in September 2012.
RESULTS: A total of 1026 renovisceral vessels (mean 3.8 ± 0.5 per patient) were targeted for preservation. One patient (0.4%) died in the institution within 30 days and 31 (11.4%) developed 36 major non-fatal complications including unplanned permanent dialysis (n = 1, 0.4%) and non-ambulatory SCI (n = 6, 2.2%). In patients with <40 mm SC coverage, none were staged or had prophylactic CSF drains and none developed SCI. In patients with ≥40 mm SC coverage, SCI occurred in 3.3% (pre-SCPP: 4/20 [20%; none staged, 13 prophylactic CSF drains] vs. post-SCPP: 2/167 [1.2%; 89 staged, no prophylactic CSF drains]; p = .001 [OR = 19.9]). Estimated survival (±SE) at one, two and three years was 92.6% ± 1.6%, 86.5% ± 2.4%, and 73.8% ± 3.5%, respectively, with no significant difference comparing extent of aneurysm or SC coverage. Forty-three (15.9%) patients required late re-intervention. Estimated freedom from re-intervention at one, two and three years was 91.9% ± 1.8%, 85.1% ± 2.5%, and 79.5% ± 3.2%, respectively.
CONCLUSION: Elective endovascular thoraco-abdominal aortic repair with SC sealing zones can be performed with low peri-operative risk and good medium-term outcomes. Selective staging without prophylactic CSF drainage contributed to a significant reduction in the incidence of SCI.
