Abstract:
Objective To explore the value of C-arm CT in transjugular intrahepatic portosystemic shunt (TIPS).Methods Between June 2015 and October 2017,a total of 16 patients with cirrhosis complicated by upper gastrointestinal bleeding or massive ascites due to portal hypertention in our center were retrospectively enrolled in the study.Abdominal enhanced CT was routinely performed before surgery.Postprocessing images of portal vein were used as a guidance of TIPS in real time after integrated with intraoperative c-arm CT images during selective operations.Results The success rate of C-arm CT-guided TIPS was 100％.Portal vein angiography showed the position basically consistent with CT matched images reference position.No obvious abdominal hemorrhage,injury of biliary tract and other complications occurred in all patients.The mean number of needle passes was 2.1 ±0.9 passes(range of 1.0-4.0 passes),the mean time of portal vein entry was 4.3 ± 1.9 min (range of 2.0-8.0 min),the mean fluoroscopy period was 22.6 ± 4.8 min (range of 17.0-32.0 min),DAP was (256.2± 96.7)mGy/cm2.Conclusion C-arm CT-guided TIPS is technically feasible and safe.
