ABSTRACT
The aim of this manuscript was to establish a consensus for the management of acute and chronic venous obstruction among specialists in the UK. Specialist physicians representing vascular surgery, interventional radiology and hematology were invited to 3 meetings to discuss management of acute and chronic iliofemoral obstruction. The meetings outlined controversial areas, included a topic-by-topic review; and on completion reached a consensus when greater than 80% agreement was reached on each topic. Physicians from 19 UK hospitals agreed on treatment protocols and highlighted areas that need development. Potential standard treatment algorithms were created. It was decided to establish a national registry of venous patients led by representatives from the treating multidisciplinary teams. Technical improvements have facilitated invasive treatment of patients with acute and chronic venous obstruction; however, the evidence guiding treatment is weak. Treatment should be conducted in centers with multi-disciplinary input; robust, coordinated data collection; and regular outcome analysis to ensure safe and effective treatment and a basis for future evolvement.

PURPOSE: Transjugular intrahepatic portosystemic shunt (TIPS) creation is used to treat portal hypertension complications. Often the most challenging and time-consuming step in the procedure is the portal vein (PV) puncture. TIPS procedures are associated with prolonged fluoroscopy time and high patient radiation exposures. We measured the impact of transabdominal ultrasound guidance for PV puncture on duration of fluoroscopy time and dose. METHODS: We retrospectively analyzed the radiation dose for all TIPS performed over a four-year period with transabdominal ultrasound guidance for PV puncture (n=212, with 210 performed successfully and data available for 206); fluoroscopy time, dose area product (DAP) and skin dose were recorded. RESULTS: Mean fluoroscopy time was 12 min 9 s (SD, ±14 min 38 s), mean DAP was 40.3±73.1 Gy·cm2, and mean skin dose was 404.3±464.8 mGy. CONCLUSION: Our results demonstrate that ultrasound-guided PV puncture results in low fluoroscopy times and radiation doses, which are markedly lower than the only published dose reference levels.
