Transjugular preoperative portal embolization (TJPE) a pilot study.

Area of Science:

• Interventional Radiology
• Hepatobiliary Surgery
• Vascular Access

Background:

• Transjugular intrahepatic portosystemic shunt (TIPS) expertise informed the development of a novel transjugular approach for preoperative portal vein embolization.
• This pilot study aimed to assess the feasibility, benefits, and drawbacks of this innovative transjugular method.

Purpose of the Study:

• To evaluate the safety and efficacy of transjugular preoperative portal embolization (TPE) as an alternative to conventional methods.
• To determine the potential advantages and disadvantages of the transjugular approach for TPE.

Main Methods:

• Ultrasound-guided puncture of the right or left portal vein via hepatic veins.
• Catheter-based embolization of the right portal branch using Histoacryl and Lipiodol mixture.
• Pre- and post-embolization duplex ultrasound and CT scans to monitor portal flow and liver hypertrophy; assessment of clinical outcomes including hospital stay and pain.

Main Results:

• Fifteen patients underwent successful transjugular preoperative portal embolization without serious complications.
• Mean hospital stay was 3.3 days; portal embolization achieved in all cases.
• Significant increase in non-embolized liver segment volume (10% within 4 weeks) and successful right hepatectomy in 12 patients.

Conclusions:

• Transjugular preoperative portal embolization is a safe, painless procedure.
• This technique is a valuable alternative for patients unsuitable for standard percutaneous transhepatic portal embolization due to factors like tumor interposition or impaired hemostasis.
