Aims and objectives: Determine if psoas density (as a representative of sarcopenia) can be used to predict survival in patients undergoing TIPS for ascites or variceal bleeding. Determine the pre-TIPS psoas density threshold value at which survivability can be predicted Our hypothesis is that measurement of psoas muscle[...]

Methods and materials: We retrospectively reviewed the medical records of 216 patients who had TIPS placed between June 2005 and June 2015. Patients with CT examination of the abdomen without IV administration of contrast material prior to TIPS were included in the study. The pre-TIPS psoas density was measured in HU by d[...]

Results: The study included 134 males (62%), 148 Caucasians (68.5%) with a mean age of 56 years (range: 29-87 years). TIPS was performed for the indication of volume overload in 110 patients (50.9%) and variceal bleeding in 106 patients (49.1%). The most common etiologies for cirrhosis were nonalcoholic stea[...]

Conclusion: The psoas density threshold for 12-month survival of patients undergoing TIPS was determined to be 49.19 HU. The survival advantage of patients with psoas density greater than 49.19 HU was statistically significant (p=0.0004) compared to patients with psoas density less than 49.19 HU. With these res[...]
