The Association of Sarcopenia and ASA Score to Spinal Cord Ischemia in Patients Treated With the t-Branch Device.

Sarcopenia has been identified as a factor of increased mortality in patients managed for aortic aneurysm repair. However, significant heterogeneity has been recorded in the tools assessing its presence. In this analysis, an already used method, combining the ASA score and psoas muscle area and attenuation, has been used to assess the impact of sarcopenia in patients managed with the t-branch device. This analysis showed that patients at low risk, with an ASA score I-II or LPMA>350cm2HU were at lower risk to evolve spinal cord ischemia. Along this line, sarcopenia may be a valuable marker for the prediction of perioperative adverse events , other than mortality, in patients managed using complex endovascular repair.
