Background Catheter‐related venous thrombosis (CRVT) is a severe complication of home parental nutrition. Although primary prevention of CRVT is crucial, there is no consensus on anticoagulant use to prevent this adversity. The aim was to compare CRVT risk in patients with chronic intestinal failure (CIF) in the presence or absence of anticoagulants, and to identify CRVT risk factors. Methods This retrospective cohort study comprised adult patients with CIF with a central venous access device (CVAD) between 2010 and 2020 that were treated at our national CIF referral center. Analyses were performed at a CVAD level. Results Overall, 1188 CVADs in 389 patients were included (540.800 CVAD days). Anticoagulants were used in 403 CVADs. In total, 137 CRVTs occurred in 98 patients, resulting in 0.25 CRVTs/1000 CVAD days (95% CI, 0.22–0.29). Anticoagulant use was associated with a decreased CRVT risk (odds ratio [OR] = 0.53; 95% CI, 0.31–0.89; P = 0.02). Left‐sided CVAD insertion (OR = 2.00; 95% CI, 1.36–2.94), a history of venous thrombosis (OR = 1.73; 95% CI, 1.05–2.84), and a shorter period postinsertion (OR = 0.78; 95% CI, 0.65–0.92) were independently associated with an increased CRVT risk. Conclusion Anticoagulants decreased the CRVT risk. In addition, we identified left‐sided vein insertion, a history of venous thrombosis, and a shorter period post‐CVAD insertion as CRVT risk factors. Further prospective studies should provide guidance whether prophylactic anticoagulant use, especially in higher‐risk patients with a left‐sided CVAD or a history of venous thrombosis, is justified.
