多层螺旋CTA:不同重建方法在主动脉瘤腔内隔绝术后的应用评价 总被引:3,自引:0,他引:3
目的:探讨多层螺旋CT血管造影不同重建方法在主动脉瘤腔内隔绝术后的临床应用价值。材料与方法:46例主动脉瘤腔内隔绝术后行多层螺旋CT血管造影,采用准直2.5mm,层厚3.0mm,螺距为6,重建方法为容积显示技术(volume rendering,VR)、表面阴影遮盖显示(shade surface display,SSD)及最大密度投影法(maximum intensity projection,MIP),并对三种方法进行比较。结果:46例中有1例术后内支架出现局限性断裂,VR及MIP均清晰显示了内支架的变化,SSD未能显示。1例内支架展开不良,三种重建方法均明确显示;6例术后出现渗漏,VR清晰显示渗漏的部位、形态及内漏量,MIP、SSD仅显示其中的5例,三者中以VR显示最佳。在显示支架内血流情况及瘤周血栓方面,VR能明确支架内有无血栓形成及腔内隔绝术后的转归变化,VR显示1例术后支架内血栓形成SSD及MIP未能显示。结论:多层螺旋CT能在较短时间内进行大范围的扫描,有利于主动脉病变的检查;VR图像优于SSD及MIP,能为术后内支架情况提供更多更准确的信息,VR技术应作为主动脉瘤内支架术后的首选三维重建方法。 相似文献

Transplant atherosclerotic coronary disease remains the leading cause of death in heart transplant recipients. We report the first case of coronary stent implantation in a heart graft for epicardial focal stenosis. Due to the lower rate of restenosis after stenting in the native coronary artery, we suggest that coronary stenting be considered an acceptable, first intention therapeutic option instead of angioplasty alone whenever possible. 相似文献

Endovascular stent implantation in patients with stenotic aortoarteriopathies: early and medium-term results. 总被引:1,自引:0,他引:1
Ernest S Siwik Stanton B Perry James E Lock 《Catheterization and cardiovascular interventions》2003,59(3):380-386
Data regarding stent implantation for stenotic aortoarteriopathy (SAA) are incomplete. We report on nine patients with this rare syndrome who underwent arterial stent implantation. Indications, results, and complications for patients with SAA were reviewed. Nine patients underwent 11 procedures. Twenty-two stents were implanted in the aorta or brachiocephalic vessels. Five patients had diffuse stenoses, three patients had middle aortic syndrome, and one patient had thoracic and abdominal coarctation. Associated diagnoses included Williams syndrome (2), neurofibromatosis (2), Takayasu's (1), and congenital rubella (1). Median gradient was 60 mm Hg (20-140 mm Hg). Poststent gradient was 15 mm Hg (0-60 mm Hg; P < 0.001). Additional stents were implanted in two patients and five underwent stent redilation. Two patients (22%) were found to have aneurysm formation. Stent implantation effectively provides gradient relief in SAA. Gradient reduction persists or is amenable to redilation. Importantly, however, uncomplicated stent implantation does not preclude aneurysm formation and may be more common than in traditional patient groups. 相似文献

Technical improvements, such as mechanical lithotripsy, stenting or nasobiliary drainage, and wire-guided cannulation, have reduced the risk of complications in endoscopic sphincterotomy. To determine the extent of this reduction in risk, we assessed the medical records of 1352 patients with common bile duct stones in whom the procedure was conducted. Complications examined were: acute cholangitis and pancreatitis. Stone clearance was achieved in 1256 patients (92.8%), with an overall morbidity rate of 7.7% and a mortality rate of 0.15%. One hundred and forty-two patients had stones with a diameter greater than 20mm; 97 of these patients did not undergo lithotripsy. Cholangitis occurred in 10 of these 97 patients (10.3%), whereas, in the 45 patients who underwent lithotripsy, there were no cases of cholangitis (P=0.02). Stone removal was not immediately accomplished or attempted in 396 patients. In 82 of these patients in whom a stent or a nasobiliary drain was placed in the common bile duct, the incidence of cholangitis was 1.2%, significantly less (P=0.045) than the incidence of 6.4% in the other 314 patients given no stenting or nasobiliary drain. To overcome difficult cannulation, precut sphincterotomy was conducted in 134 patients and wireguided sphincterotomy, a recently introduced procedure, was conducted in 55 patients. When the precutting technique was used, the incidence of acute pancreatitis was significantly higher (8/134; 6.0%) than that in the patients in whom the standard procedure was conducted, i.e., neither the precut technique nor wire-guided ES was used (23/1218; 1.9%) (P=0.008). There were no cases of pancreatitis in the 55 patients in whom wire-guided sphincterotomy was performed, although the difference was not statistically significant because of the small number of patients (P=0.06). Based on these findings, we conclude that improved technologies have led to a significant reduction of complications in endoscopic sphincterotomy. 相似文献
