Balloon Dilatation of the Pulmonary Valve in a Patient with Pulmonary Atresia and Intact Ventricular Septum Using a Commercially Available Radiofrequency Catheter

Using a commercially available 5F deflectable radiofrequency catheter, we have succeeded in percutaneous valvotomy of an imperforate pulmonary valve and consecutive balloon dilatation in a baby with pulmonary atresia and intact ventricular septum. After the procedure, right ventricular systolic pressure fell from 125 mmHg to 65 mmHg, and right ventriculography demonstrated anterograde blood flow into the pulmonary arteries. There were no major complications. Doppler echocardiography at 1 year after the procedure demonstrated a pressure gradient across the pulmonary valve of 20 mmHg with mild pulmonary and tricuspid regurgitations.     

Successful Embolization of Coronary Arteriovenous Fistula Using an Interlocking Detachable Coil

Although the efficacy and feasibility of coil embolization of coronary arteriovenous fistulas have been reported, the procedure may be complicated by migration of the coil into peripheral vessels or pulmonary arteries. We report two cases of successful coil embolization of such lesions using an interlocking detachable coil. This system can provide safer and more effective coil embolization in patients with coronary arteriovenous fistula.     

Stepwise interventional approach in a neonate with pulmonary valve atresia and intact ventricular septum

In neonates with pulmonary atresia and intact ventricular septum the aims of therapy are maintenance of pulmonary blood flow and right ventricular decompression in order to achieve right ventricular support of the pulmonary circulation. Recent developments in interventional heart catheterization with pulmonary radiofrequency-assisted balloon valvuloplasty and ductal stent implantation offer an alternative to the classical surgical approach. We report on a neonate with membranous pulmonary atresia and intact ventricular septum, in whom a large interatrial right-to-left shunt via the foramen ovale persisted after radiofrequency-assisted pulmonary balloon valvuloplasty on the 2nd day of life. The interatrial shunt prevented adequate right ventricular filling and antegrade pulmonary perfusion leading to severe cyanosis (transcutaneous oxygen saturation 40%). In order to increase pulmonary blood flow and raise left atrial pressure, the arterial duct was stented. After ductal stenting, prostaglandin was discontinued and the transcutaneous oxygen saturation remained stable around 89%. At follow up after 7 weeks the foramen ovale had decreased in size and only a small left-to-right shunt was present, documenting the effectiveness of this approach. Conclusion Based on the present case we propose a stepwise interventional approach for the neonate with pulmonary atresia and intact ventricular septum. If cyanosis persists after isolated pulmonary valvuloplasty despite adequate right ventricular function, ductal stent implantation can reduce interatrial shunting and thus improve oxygen saturation.

动脉插管化疗治疗中晚期膀胱肿瘤(附11例报告)

目的探讨动脉插管化疗对于中晚期膀胱肿瘤的治疗效果。方法对１１例由于年龄大、体质差、发现较晚、不能耐受麻醉和手术的中晚期膀胱肿瘤患者，采用了动脉插管化疗。结果１１例患者治疗后平均存活时间为２６．２±１３．１个月，１年生存率为８１．８％，总有效率为９０．９％，不良反应轻微。结论动脉插管化疗是目前治疗中晚期膀胱肿瘤的一种较好方法。     

介入治疗结合分次立体定向适形放疗交替治疗肝癌的疗效评价

目的:比较肝动脉化疗栓塞(TACE)与联合分次立体定向适形放疗(FSCR)交替治疗原发性肝癌的疗效.方法:90例PHC患者随机分成单纯介入组与介入加放疗组(综合组).综合治疗组采用TACE结合FSCR,观察近期疗效与生存率,并用COX比例风险模型分析预后因素.结果:综合治疗组和对照组1、3、5年生存率分别为91.1%、62.2%、24.4%和73.3%、37.8%、8.9%,两组生存率比较差异有显著性(P＜0.05).结论:放疗对病灶周边门静脉供血为主的肿瘤病灶的杀灭,是本疗法比单纯介入治疗(TACE)疗效增高的关键.综合治疗组中肿瘤直径、肿瘤数目、Child分级、Okuda分期为影响预后的最主要因素.     

Therapeutic effect of transcatheter arterial chemoembolization on hepatocellular carcinoma: evaluation with contrast-enhanced harmonic power Doppler ultrasound

The aim of this study was to investigate the usefulness of contrast-enhanced harmonic power Doppler ultrasound (US) for the detection of residual viable hepatocellular carcinoma (HCC) after treatment with transcatheter arterial chemoembolization (TACE). Forty-seven patients with 68 HCC lesions 1.8–9.5 cm in diameter (mean ± SD 4.3 ± 1.7 cm) underwent contrast-enhanced power Doppler US, in the harmonic mode, before and after treatment with TACE. Unenhanced spiral CT and contrast-enhanced dynamic MR imaging were also performed to help establish the outcome of therapy. Before treatment, intratumoral blood flow signals were detected at contrast-enhanced harmonic power Doppler US in 65 (95 %) of 68 lesions. After TACE, flow signals were no longer detectable in 22 of these 65 lesions, which showed complete response at spiral CT and dynamic MR imaging. In 38 (88 %) of the 43 lesions with partial response, intratumoral flow signals were still identified at contrast-enhanced harmonic power Doppler US. Twenty-eight of these 38 lesions underwent additional treatment with percutaneous ethanol injection (PEI) using contrast-enhanced harmonic power Doppler US guidance. Complete response was seen after PEI in 23 of 28 lesions. Contrast-enhanced harmonic power Doppler US proved useful for assessing the therapeutic effect of TACE on HCC and for guiding additional treatment with PEI in cases of partial response.

Technical aspects of venous stenting in high-grade stenoses using a long guidewire between dual venous access sites

We describe the technical benefits of the dual-access technique for venous stenting in high-grade stenosis. Stents were implanted successfully with this technique in all patients, although the preceding transfemoral interventions had failed. The dual-access technique is useful to facilitate the intervention when the stenoses are too severe to place the stent through just a single access point.

Iatrogenic dissection of the portal vein during TIPS procedure

Dissection of the portal vein is a rare entity which has been rarely described during transjugular intrahepatic portosystemic shunt (TIPS) procedure. We report three cases of dissection during this procedure and their complications. One dissection was immediately treated with coaxial stents. The two others were complicated either by a thrombus or by a false aneurysm. In the first case a second parallel stent was used to treat this complication. The patient with the portal vein false aneurysm was transplanted 4 days after this diagnosis. Portal vein dissection in TIPS procedure appeared to be less rare than has been reported and must be considered as a potential cause of TIPS dysfunction.
