Objective To explore the effect of endovascular treatment guided by ultrasonography combined with portosystemic shunts on the patients with Budd-Chiari Syndrome （BCS）.Methods The clinical data of 136 patients with BCS treated by balloon angioplasty and stent implantation guided by Doppler ultrasonography in our hospital from January 1995 to January 2011 were retrospectively analyzed.After balloon angioplasty,53 patients were treated by inferior vena cava （IVC） stent implantation and 31 patients with hepatic venous occlusion underwent portosystemic shunts （PSSs） at one week after endovascular treatment.The long-and short-term effects after treatment were studied.Results After endovascular procedures,the IVC pressure of patients significantly decreased （P＜0.01）,while IVC diameter, flow velocity in the lesion,and right atrial pressure of patients showed significant increase（P＜0.01）.Slight heart dysfunction appeared in 13 cases of patients.After shunting,acute pancreatitis occurred in 3 cases, and 1 patient died of upper gastrointestinal hemorrhage on the 10 d after PSSs.Doppler ultrasonography for IVC and shunt vessels showed：the swollen liver and spleen lessened on 3d after endovascular procedures.The swollen liver lessened 2-7cm （mean 5.5cm）,swollen spleen lessened 3-8cm （mean 5.8cm）, and the time of ascites disappearance was 3-60d （mean 14d）.All the patients were followed up for 1 month to 15 years with an average of 3 years.Restenosis of the distal part of stent was found in 1 patient in 2 years after operation, hepatic vein occlusion occurred in 1 case in 1 year after treatment,hepatocellular carcinoma occurred in 1 patient in 3 years after stent implantation,and 1 patient died of C type hepatitis after 1 year,and 5 out of 6 cases of patients with infertility had babies after 1 year.All patients had no stent migration or occlusion of shunts and the symptoms of portal hypertension were obviously relieved.Conclusions Endovascular treatment guided by Doppler ultrasonography is a convenient,safe,and effective method for BCS.Portosystemic shunts are commended to patients with hepatic venous occlusions.The above mentioned methods provide a feasible and effective means for IVC stenosis and short segment occlusion with hepatic vein occlusion of BCS.
Objective To investigate the clinical effect and safety of balloon angioplasty (BAP) for patients with venous hypertension associated with autogenous arteriovenous fistula (AVF). Methods Thirty-three patients with venous hypertension associated with AVF were hospitalized between August 2012 and August 2014 in the Department of Nephrology, West China Hospital of Sichuan University. All of the patients received BAP therapy. The clinical characteristics and therapeutic effects were comparatively summarized before and after operation. Results Venous hypertension in all the 33 patients was caused by central venous stenosis or occlusion. Among them, there were 13 cases of stenosis on the site where the left innominate vein crossed the aorta, 10 cases of stenosis at the junction of the left innominate vein and superior vena cava, 4 cases of stenosis at the junction of the left subclavian vein and the innominate vein, 3 cases of right innominate vein stenosis, and 3 cases of innominate vein occlusion. The lesions were most common in the innominate vein. Innominate vein stenosis or occlusion occurred in 19 cases (57.6%), and stenosis at the junction of innominate vein and the superior vena cava or subclavian vein occurred in 14 cases (42.4%). Of the 33 patients, one patient with complete occlusion of the innominate vein did not receive BAP treatment because guide wire could not pass through the occlusion site. The other 32 patients underwent BAP treatment, among whom 30 (93.8%) were successful, and 2 (6.2%) failed. No obvious complications occurred. One day after BAP treatment, patients’ symptoms were significantly relieved. One to seven days later, swelling of the hands, pain, and other symptoms were relieved. In the 30 patients who underwent the treatment successfully, 29 were followed up for 3 to 24 months. Among them, 21 (72.4%) maintained clinical remission and the AVFs were functional, 6 patients (20.7%) got a restenosis later, and 2 patients died. Conclusions BAP is effective and safe for venous hypertension associated with AVF. However, the follow-up of patients has displayed the possible risk of restenosis in long-term outcomes.
