彩色多普勒超声在诊治医源性股动脉假性动脉瘤中的应用价值

目的评价彩色多普勒超声在诊治医源性股动脉假性动脉瘤中的应用价值。方法应用线阵高频探头对35例临床怀疑有假性动脉瘤的患者进行彩色多普勒超声检查,观察其形态、大小、内部回声及血流形态、频谱特征。对明确诊断的31例患者在超声定位下手指局部压迫60min后用弹力绷带加压,平卧8h。结果35例患者中31例在穿刺部位出现囊性肿块,囊腔内有涡流,囊颈部呈“双期双向”血流频谱,确诊为假性动脉瘤,对这31例患者在超声引导下局部压迫修复,29例1次压迫成功,2例重复压迫成功,无并发症及复发。结论彩色多普勒超声能够正确诊断假性动脉瘤;对明确诊断患者,在超声引导下手指压迫修复治疗是一种安全、可靠、简单的方法。     

Successful embolization of a bleeding splenic artery pseudoaneurysm secondary to necrotizing pancreatitis

A case of successful obliteration of a bleeding splenic artery pseudoaneurysm secondary to necrotizing pancreatitis is reported. The material used for embolization was stainless steel coils. A variation of the technique is introduced. Instead of occluding the pseudoaneurysm cavity itself, embolization only of the afferent vessel is advised.     

股部假性动脉瘤伴感染16例临床分析

目的：探讨股部假性动脉瘤伴感染的原因，部位，诊断和治疗。方法：对16例股部假性动脉瘤伴感染患者进行手术治疗。结果：原因有局部蜂窝织炎4例，开放骨折使用外固定支架并针道感染2例，医源性穿刺损伤2例，股动脉毒品注射8例。病变部位；旋股外侧动脉分支2例，股浅动脉7例。股深动脉2例，股总动脉3例，旋股外侧动脉总干，胫后动脉分支各1例，所有患者均手术治疗并切除假性瘤壁，10例行动脉重建，6例直接结扎或缝扎分支动脉。结论：外伤特别是毒品注射易导致股动脉主干假性动脉瘤伴感染，动脉造影可确诊，主要采用手术治疗，主干动脉需需行动脉重建。     

动脉穿刺致假性动脉瘤原因及治疗对策探讨

目的探讨动脉直接穿刺致假性动脉瘤的发生原因及治疗效果。方法分析本院介入诊疗中心2009年10月～2010年5月525例直接穿刺动脉导致的4例假性动脉瘤患者的临床及治疗情况。结果 4例均治愈,其中3例徒手压迫,1例行外科修补。结论股动脉直接穿刺术后患者发生股动脉假性动脉瘤与多种因素有关,治疗上可以采用直接压迫、外科修补、瘤腔内注射凝血酶的方法来治疗。     

肝动脉假性动脉瘤破裂出血的介入栓塞治疗

目的探讨肝动脉假性动脉瘤（HAPA）破裂出血急诊栓塞治疗的方法、疗效。方法 2005年4月至2009年10月间对6例肝动脉假性动脉瘤破裂出血进行急诊血管内介入栓塞治疗,造影明确假性动脉瘤部位后,将导管超选择插至载瘤动脉,选用弹簧圈、聚乙烯醇颗粒进行栓塞。结果全部6例经肝动脉造影后明确显示假性动脉瘤,5例位于肝右动脉,肝左动脉1例,肝固有动脉1例。经介入栓塞治疗后载瘤动脉闭塞,假性动脉瘤显影消失,随访3-36月出血无复发。未见与介入治疗相关的并发症。结论对肝动脉假性动脉瘤破裂出血,急诊介入栓塞治疗,方法简单、疗效可靠。应作为首选治疗方法。     

彩色多普勒超声在诊治股动脉穿刺并发症中的应用

目的探讨彩色多普勒超声在股动脉穿刺并发症监测治疗中的应用。方法首先对术后存在皮下淤血、软组织肿胀的350例患者进行彩超检测,确定是否存在并发症、并发症的种类及性质,如果确定为假性动脉瘤即用彩超引导压迫治疗并评价其疗效。结果共有150例患者发生皮下血肿,30例发生假性动脉瘤,5例发生动静脉瘘,5例发生静脉血栓,2例股动脉出现管腔节段性狭窄（由于周围血肿较大压迫所致）。结论彩色多普勒超声对股动脉穿刺的各种并发症能够作出准确诊断,并可指导压迫治疗假性动脉瘤。     

Successful utilization of coronary covered stents to treat a common hepatic artery pseudoaneurysm secondary to pancreatic fistula after Whipple’s procedure: Report of a case

A 73-year-old man underwent a pylorus-preserving Whipple’s procedure for distal cholangiocarcinoma. His postoperative course was complicated by the formation of a pancreatic fistula, which was initially managed conservatively. On postoperative day (POD) 86, he lost 100 ml of blood from the site of the pancreatic fistula. Contrast-enhanced computed tomography (CT) showed a pseudoaneurysm, 12 mm in diameter, in the common hepatic artery. The diameter of the pseudoaneurysm increased to 15 mm on POD 89, so we implanted coronary covered stents to prevent massive bleeding from rupture and to retain hepatic arterial flow. Six days after implantation, computed tomography findings confirmed a thrombosed pseudoaneurysm as well as patent hepatic arterial flow. Follow-up CT 18 months after surgery showed patent hepatic arterial flow. There have been no signs of rebleeding or abnormal liver function.     

Successful endovascular reconstruction of acutely ruptured pseudoaneurysm of the vertebral artery,complicated by isolated vertebrobasilar circulation and symptomatic vasospasm

The management of a ruptured pseudoaneurysm of intracranial vertebral artery (VA), which is the sole supplier to an isolated vertebrobasilar system, is challenging. The authors report on such a case in a 49-year-old man who suffered a grade III subarachnoid hemorrhage (SAH) caused by a dissecting fusiform pseudoaneurysm of the left VA. The right VA terminated in the posterior inferior cerebellar artery and posterior communicating arteries were absent. The patient developed symptoms consistent with vasospasm on day 9 after SAH, which was treated by intra-arterial vasolytic therapy, followed by stent placement and “in-stent” balloon angioplasty. Angiography 2 weeks later showed near-complete resolution of the pseudoaneurysm. At discharge, the patient's modified Rankin score was one. In this complicated case in which an isolated vertebrobasilar circulation precluded parent vessel sacrifice, we detail the successful management using a combination of intra-arterial vasolytic therapy, stent reconstruction, and balloon angioplasty.     

Delayed pseudoaneurysm repair: A case report

Iatrogenic pseudoaneurysms are a complication of arterial catheterization performed for both diagnosis and intervention. Their incidence is approximately 1% following diagnostic catheterizations and 3.2% after interventional procedures. The symptoms of iatrogenic pseudoaneurysm are pain and swelling. The preferred method of treatment consists of thrombin injection under ultrasound guidance, although compression can be used. Most published research describes pseudoaneurysms that occurred close to the time of catheterization; the present case report describes a patient who presented two years postcatheterization with a symptomatic pseudoaneurysm.
