In situ saphenous vein grafts are being used with increasing frequency for bypass procedures involving the femoral and popliteal arteries. Complications of these procedures include anastomotic stenoses and persistent arteriovenous fistulae that may result in failure of the graft. Balloon angioplasty and embolotherapy with detachable balloons were employed successfully in three or four recent cases of patients with complications from in situ grafts. Tailored angiography is essential for evaluating in situ grafts, and interventional techniques are extremely useful for managing complications. 相似文献

目的:了解乌审旗妇女宫颈癌及癌前病变的发病现状,探讨子宫颈液基细胞学(Thinprep paptest,TCT)结合阴道镜检查的诊断价值。方法:对3 000名乌审旗妇女进行TCT筛查,对TCT阳性(细胞学TBS分类为不典型鳞状细胞以上)的妇女进行阴道镜及镜下多点活组织检查(活检),分析TCT阳性者的阴道镜检查及活检结果,比较TCT阳性者中不同年龄段患者的活检结果。结果:3 000名受检者中,TCT阳性537例(17.9%),其中经活检证实为宫颈上皮内瘤变(cervical intraepthelial neoplasia,CIN)190例(6.3%),宫颈浸润癌2例(0.07%),537例TCT阳性者中,阴道镜检查正常264例(49.2%),其中活检结果为CIN34例,阴道镜的假阴性率为12.9%,异常273例(50.8%),其中活检结果为湿疣34例,CIN或浸润癌158例,阴道镜与活检的诊断符合率达70.3%(192/273)。TCT为轻度鳞状上皮内病变、高度鳞状上皮内病变、鳞状细胞癌的病例与活检的诊断符合率分别为50.4%,88.3%和2/2,假阳性率则分别为49.6%、11%和0。537例TCT阳性者中,2030岁组、3140岁组,4147岁组的CIN检出率分别为33.7%、44.5%2、6.7%(P〈0.05)。结论:乌审旗妇女CIN的发生率高,是宫颈癌的高发人群。TCT结合阴道镜检查是较好的宫颈癌筛查手段之一。 相似文献

Corpus callosum and limbic system: neuroanatomic MR evaluation of developmental anomalies 总被引:4,自引:0,他引:4

Agenesis of the corpus callosum is a complex malformation of the brain that has been associated with varying degrees of limbic system maldevelopment. We retrospectively reviewed the records of 11 patients with callosal agenesis (seven total, four partial) who underwent magnetic resonance (MR) imaging, with particular attention to the associated malformations of the limbic system. Comparison was made with selected images from MR examinations of healthy volunteers and with necropsy specimens from other patients with callosal agenesis. Ten of 11 patients demonstrated limbic anomalies (severe motion artifact precluded evaluation of these structures in one patient). MR depicted not only the abnormalities intrinsic to callosal agenesis but also the frequently associated malformations of the limbic system. 相似文献

Pulmonary arteriovenous malformations: techniques and long-term outcome of embolotherapy 总被引:23,自引:0,他引:23

Over a 10-year period, 276 pulmonary arteriovenous malformations (PAVMs) were occluded with balloon embolotherapy in 76 patients, 67 (88%) of whom had hereditary hemorrhagic telangiectasia. Eleven patients (14%) were discovered by means of family screening with measurement of arterial blood gases and chest radiography. Epistaxis, dyspnea, hemoptysis, and hemothorax occurred in 79%, 71%, 13%, and 9% of patients, respectively. Clinical histories of strokes and transient ischemic attacks were present in 18% and 37% of patients, respectively. Computed tomographic scans of 59 patients showed stroke in 36%. Sixty-five percent of PAVMs were located in the lower lobes, which correlated with the finding of more pronounced hypoxemia in the upright position. After embolotherapy, symptomatic hypoxemia was corrected, and serial values have remained constant for 5 years. Complications were minimal, and no patient required surgery. Balloon embolotherapy is effective long-term therapy for PAVMs, and family screening should be pursued because of the possibility of a higher frequency of paradoxical embolization (stroke) than previously recognized. 相似文献
