Abstract:
Objective To evaluate the therapeutic efficacy of percutaneous transhepatic portal vein balloon angioplasty in treating cavernous transformation of portal vein following operation of congenital choledochal cyst. Methods From 2012 to 2014, a total of 6 patients with cavernous transformation of portal vein which occurred after the operation of congenital choledochal cyst were encountered at authors’ hospital. The clinical data were retrospectively analyzed. Before treatment, all patients presented symptoms of different degrees of hematemesis. Percutaneous transhepatic portal vein balloon angioplasty was carried out in all patients, and embolization of gastric coronary vein with coils was employed if angiography showed that coronary vein of stomach was pronouncedly dilated. The clinical manifestations, the imaging materials and the complications were analyzed. All the patients were followed up for 3 - 31 months. Results Of the 6 patients, portal vein main stem occlusion was found in 5 and severe localized stenosis was seen in one. Cavernous transformation of portal vein was revealed in all the 6 patients. Percutaneous transhepatic portal vein balloon angioplasty was successfully accomplished in 5 patients and failed in one patient. Embolization of gastric coronary vein with coils was performed in two patients. After the treatment, no treatment-related severe complications occurred in all patients. The follow-up period ranged from 3 to 31 months. During the follow-up period portal vein maintained patent in 5 patients. No recurrent hematemesis occurred in all patients. Conclusion For the treatment of cavernous transformation of portal vein occurring after the operation of congenital choledochal cyst, percutaneous transhepatic portal vein balloon angioplasty is a safe, effective and minimally - invasive therapeutic means.
