Hepatic falciform artery

The hepatic falciform artery is an occasional terminal branch of the left or middle hepatic artery, and may provide an uncommon but important collateral route when the principal visceral arteries are occluded.     

Laparoscopic enucleation of a renal cell carcinoma

The purpose of this study was to report on the feasibility of laparoscopic excision of renal cell carcinoma. An 81-year-old female with renovascular disease underwent a laparoscopic excisional operation for a 2-cm tumor localized in the left kidney.Pathological evaluation showed a low-grade tumor without any extension through the renal capsule (grade I Hand Broder, stage I Robson). The postoperative course was uneventful; there was minimal postoperative pain. The patient was discharged home on the sixth day. Laparoscopic excision would appear to be a safe and effective technique in selected cases.     

Is there still a place for angiography in the management of renal mass lesions?

In recent years, the development of noninvasive imaging modalities for exploration of the kidney has markedly reduced the use of angiography in the evaluation of renal masses. Presently, it is not required in routine practice to evaluate renal masses. Ultrasound is the most efficient procedure in detecting renal tumor. It is acknowledged that arteriography has a limited diagnostic and staging value compared with CT and MRI for the assessment of renal cell carcinomas (RCC). Most urologists recommend partial nephrectomy or tumor enucleation in an effort to preserve as much as possible functioning renal tissue. In such cases a preoperative map of the renal vasculature is not needed. Information on the main renal artery(ies) and segmental renal arteries can be provided with spiral CT or dynamic MR angiography. Arteriography remains useful in exceptional situations. Interventional arteriography is becoming an important part. It is indicated by means of selective embolization for the treatment of potentially bleeding tumor (i. e. angiomyolipoma) or in emergency in cases of acute hemorrhage. Less frequently, it may be proposed as a palliative procedure for inoperable patients with huge renal tumor. Two other indications of interventional arteriography are acknowledged. Some urologists request preoperative embolization of the tumor-harboring kidney to decrease/avoid extensive blood loss during surgery and/or to facilitate surgery with huge renal tumors when the renal vessels are difficult to reach. The complications of nephron-sparing surgery (partial nephrectomy or tumor enucleation) related to bleeding or arteriovenous fistulas may be cured by arterial embolization.

肝癌肝动脉灌注化疗与栓塞40例疗效观察

目的：观察肝动脉插管化疗及栓塞对肝脏恶性肿瘤的治疗效果。探讨影响疗效的有关因素。方法;在Ｘ线电视监视下将导管选择性地插至肝动脉及肿瘤供血动脉进行数字减影血管造影,根据造影结果进行肿瘤组织的栓塞及灌注化疗。结果：共插管治疗１５４例次,血管造影显示门静脉癌栓４例,肝动脉－门静脉瘘７例,肝动脉－肝静脉瘘３例。经治疗生存期超过半年者占５２．５％（２１／４０）,结论：经导管肝动脉化疗栓塞是肝癌的有效治疗途径     

高龄患者经桡动脉和股动脉行冠状动脉造影和支架植入术的效果分析

目的对比高龄患者中经桡动脉和股动脉途径行冠状动脉造影和支架植入术的安全性、可行性及疗效。方法216例接受介入诊疗的75岁以上冠心病心绞痛病人,随机分为桡动脉组及股动脉组,各108例。比较两组在冠脉造影及支架植入术中的动脉穿刺及手术操作时间、X线曝光时间、造影剂用量、支架植入数量、支架植入成功率、外周血管并发症发生率,以及支架植入术中两组特殊导管使用率,双钢丝及PTCA球囊使用率等的差异。结果桡动脉组及股动脉组的血管穿刺时间、穿刺成功率、造影成功率、支架成功率均无显著差异(P>0.05),术后不适反应发生率桡动脉组显著低于股动脉组;单个支架操作时间、特殊导管使用率、双钢丝及PTCA球囊使用率,桡动脉组均较股动脉组高,差异具有显著性(P<0.01),局部血管并发症率及术后患者舒适度、缩短住院时间,桡动脉组明显优于股动脉组,差异具有显著性(P<0.01)。结论高龄患者经桡动脉与股动脉途径介入诊疗具同样的安全性,可行性及疗效。     

老年2型糖尿病性下肢动脉病变的腔内治疗

目的 观察并总结腔内治疗老年2型糖尿病严重下肢动脉病变的临床疗效及技术经验.方法 收集2010年2月-2012年2月55例老年2型糖尿病性下肢动脉疾病患者,采用INVATEC-DEEP长球囊,进行下肢动脉经皮穿刺血管腔内成形术（percutaneous transluminal angioplasty,PTA）治疗,观察治疗前后的临床症状、体征及踝肱指数（ankle brachial index,ABI）的改变,并进行随访.结果 55例患者共55条肢体接受了腔内治疗,技术成功率为74.5％（41/55）,无并发症发生.共随访6m,失访率为0;其中,技术成功组所有患肢血供明显增加,相应节段肢体皮温升高,足背动脉搏动增强,麻木感和痛感显著减轻,生存率为95.1％,肢体存活率97.6％;技术失败组患者生存率为78.6％,肢体存活率71.4％,随访期间ABI为（0.78±0.13）.结论 腔内治疗老年2型糖尿病性下肢动脉疾病技术成功率高,临床疗效显著,但远期效果有待进一步随访.
