D.E., 68 years - temporary paraplegia postoperativ
Universitätsklinikum Regensburg
• Risk of paraplegia during BEVAR
varies between 10 – 25 %
Thorakoabdominal aortic aneurysms (TAAA)

Bisdas T et al. J Vasc Surg 2015; 61: 1408-1416.
Risk factors for paraplegia:
- Overstenting LSA
- Infrarenal surgical graft (Tube, Y) or Stentgraft
- Length of aortic coverage
- Immediate thrombosis of aneurysm
- Hypotension peri- / postoperativ
- No Spinaldrainage ?
T-Branch (Cook®)
proximal diameter 34mm
distal diameter 18mm
„Thoracic Reducing Union“
CMD Cook®
External stent graft - 38-44 mm
Internal - 32 mm
2015 - 16 implantations in 4 Vascular Centers
preoperative CTA scan
M, 60, symptomatic TAAA
Regular setup in BEVAR for TAAA
- Transposition of LSA if covered
- Spinal drainage for 3-4 days (until postop. CTA) - Orbita-US
(LiquoGard7)
- open perfusion branch (TASP) and staged procedure - MEP´s
- perfusion of internal ilac arteries - Iliac-Branch
- limited coverage of the aorta
- preserving intercostal arteries
- preoperativ ASA 100mg/daily – intraoperativ Heparin with ACT>300“
Conclusion
„2 in 1“ Stentgraft allows
T-Branch seal in the distal descending aorta
with diameter 30-38mm
without extension of the aortic coverage
„2 in 1“ Stentgraft
to reduce aortic coverage
in T-Branch
