Interventional radiological techniques in the management of hepatic artery stenosis after liver transplantation / 中华器官移植杂志

Objective To evaluate the safety and efficacy of the interventional techniques for the management of hepatic artery stenosis (HAS) after orthotopic liver transplantation (OLT).Methods Seven patients diagnosed with HAS after OLT were treated with interventional procedures. Three (patients) presented with biliary ischemic complications, 1 with hepatic abscess, and 3 with elevation of liver enzymes and bilirubin levels. Interventional techniques included transcatheter hepatic arterial thrombolysis with a low dose of urokinase (UK), and stent placement in the stenotic segment of the hepatic artery. All patients were followed up regularly by duplex ultrasound scan after discharge.(Results) HAS with over 70 % degree at the anastomosis was found in 3 patients. Complete occlusion of the proper hepatic artery was found in 4 patients, and the hepatic artery flow was re-established in these patients at 3 to 7 days after transcatheter hepatic arterial thrombolysis. However, an over 90 % degree of stenosis at the anastomosis was seen in 4 cases. Stent placement in the stenotic segment of the hepatic artery was performed successfully in 7 patients, and significant improvement of liver (function) was seen in these patients at 2 weeks after the procedures. No complications related to the procedure occurred. The 7 patients had a good clinical course with normal graft function during a mean follow-up of 9 months (4 to 18 months), and patent hepatic artery flow was identified by follow-up Doppler ultrasonography.Conclusion Transcatheter endovascular interventional techniques are safe and effective methods for treatment of HAS after OLT.

Interventional therapy for portal venous thrombosis / 中国普通外科杂志

Objective To assess the efficacy and safety of interventional techniques for the management of symptomatic portal vein (PV) and superior mesenteric vein (SMV) thrombosis. Methods Six patients with thrombosis of the PV and SMV were treated by transjugular intrahepatic portosystemic (TIPS) approach. Contrast PV SMV venography was carried out to verify the access to the PV branch. Then a 8F large bore catheter was used to aspirate thrombus. A J shaped guide wire and pig tail catheter were used to fragment the thrombus. Local thrombolysis with urokinase (UK) was delivered through a catheter in the SMV. An 4 French multiple side hole catheter was put into the SMV and UK was continuously infused for 3 to 13 days.Results The procedure was successful in all cases. One patient died of intra abdominal sepsis 12 days after. Five patients were followed up by color Doppler ultrasonography for 4～36 months with confirmed patency of the PV and SMV in all these patients. Conclusions This procedure is both safe and effective in the treatment of symptomatic PV and SMV thrombosis.

Objective To evaluate interventional techniques for the management of splanchnic artery areurysms. MethodsThere were 11 cases including splenic artery aneurysm in 5 cases, gastroduodenal in 5, and superior mesenteric artery (SMA) aneurysm in 1. Five patients presented with ruptured pseudoaneurysms and bleeding. Three patients presented with abdominal pain and epigastric pulsatile mass. Three patients were asymptomatic. Transcatheter endovascular coil embolization was used in 10 patients. Combination of the endovascular embolization and stent-graft placement in the SMA was performed in 1 patient with SMA areurysm. ResultsTechnical success was achieved in all cases with no significant complications. Hemostasis was achieved in all 5 patients. One patient was cured by combination of stenting and endovascular coil embolization. An average follow-up of 25.5 months in 11 cases revealed no complications. Doppler ultrasound scan showed complete thrombosis and occlusion of these aneurysms. ConclusionsTranscatheter endovascular interventional techniques are safe and effective methods for the treatment of splanchnic artery areurysms.

Hepatic Encephalopathy after Transjugular Intrahepatic Portosystemic Stent Shunts. Potential Risk Factors and Its Prophylaxis / 介入放射学杂志

Purpose: To study the incidence of new or worsened hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic stent shunts (TIPSS) and to identify periprocedural factors influeneing patients at risk. Materials and methods: Between March 1993 and March 1997, 264 patients were treated with TIPSS. 212 patients were possible to assess the development of encephalopathy comprising the wholersome study data, 148 men and 64 women with age ranging from 18 to 74 years old. All patients underwent more than 3 months of clinical follow-up (3~45 months). 118 patients (55.66%) were categorized as Child's class A, 69 patients (52.55%) as Child's class B, 25 patients (11.75%) as Child's C. The diametes of the stent were 8mm im 41(18.87%) patients and 10 mm in 171(81.13%). We analyzed the following factors: age, sex, Child's classification the degree of liver atrophy, TIPSS in emergency or not, and size, the curvature of the shunt tract, portacaval gradient (PCG) before and after TIPSS, embolization of the gactric varices, blood ammonia level, derection of portal vein flow detected with color Doppler imageng after shunt. Statistical methods were used with Student's test, X~2 test, rand sum tets, linear regression and correlation, and multeple limear regressin. Results: The overall incidence of nwe and worsened HE was 16.03% (33/212). Of these, 27 patients were claigced as minimal (grade Ⅰ) and 6 advanced (grade Ⅱ). By Child's classification, new or worsening HE was seen in 8.47% of class A, 11.59% of class B, 60.0% of class C. TIPSS- related HE was correlated to Child's classification (r=0.86). As regard to shunt siza, the HE rate of 8mm stent was 7.31% (3/41), 10mm stent was 17.54%(30/171), and the difference between the two groups wss statistically significance (P

Gadopentetate dimeglumine as contrast agent for arteriography and interventional radiologic procedures: preliminary application / 介入放射学杂志

Objective To investigate the feasibility of gadopentetate dimeglumine as contrast agent for arteriography and interventional procedures.Methods Nine patients received gadopentetate dimeglumine as contrast agent during interventional procedures. Gadopentetate dimeglumine was used in 2 patients with contraindications to iodinated contrast media. In addition to the standard injection sequences with iodinated contrast media, arteriograms were obtained after administration of gadopentate dimeglumine in seven patients. Diagnostic arteriographies were performed in thoracic aorta, common carotid artery, bronchial artery, intercostal artery, hepatic artery, iliac artery and uterine artery. The doses of gadopentetate dimeglumine used in this series were≤0.3 mmol/kg. Vital signs and arterial oxygen saturation were monitored during the procedures. The blood and urine routine examinations, the hepatic and renal functions tests were done after the procedure. Results There were no significant differences between the gadopentetate dimeglumine and the iodinated contrast media examinations for illustrating the main trunk of these arteries. Angiograms obtained with the iodinated contrast media appeared to be better than that of with gadopentetate dimeglumine for visualizing the distal branches of these arteries and the tumor stain. The interventional procedure was completed successfully in the two patients using gadopentetate dimeglumine alone. No patient suffered from complication related to the use of gadopentetate dimeglumine, and also no worsened renal function was shown after the procedure. Conclusions Diagnostic arteriograms can be achieved safely and successfully by using gadopentetate dimeglumine, especially in patients with allergy to iodinated contrast media and chronic renal insufficiency.
