Compression ultrasonography. Treatment for acute femoral artery pseudoaneurysms in selected cases.

Treatment of pseudoaneurysms has traditionally been surgical. We evaluated 12 patients who developed femoral artery pseudoaneurysms after cardiac catheterization. Using color Doppler ultrasonography steady pressure was applied, occluding flow in both the neck and body of the pseudoaneurysm for 10 minute intervals. Six patients were treated successfully. We believe the same technique was unsuccessful in five additional patients because compression of a short (< 5 mm) or wide neck is ineffective. In one patient the pseudoaneurysm thrombosed spontaneously prior to a treatment attempt. We believe compression ultrasonography of pseudoaneurysms should be offered as a therapeutic alternative to surgery in selected cases.

Percutaneous ultrasonographically guided thrombin injection of iatrogenic pseudoaneurysms in unusual sites.

OBJECTIVES: To evaluate the effectiveness and safety of percutaneous ultrasonographically guided thrombin injection as treatment of unusually positioned and unusually large iatrogenic pseudoaneurysms. METHODS: Five patients with iatrogenic pseudoaneurysms were evaluated by color duplex ultrasonography. Two patients had additional digital angiography, and 2 had additional computed tomographic angiography. In 3 of the patients, large, painful iatrogenic pseudoaneurysms located proximal (2 patients) and distal (1 patient) to the arteriovenous hemodialysis fistulas had developed, most likely due to erroneous puncture of the arterial side (brachial artery) or venous side (cephalic vein) of the fistulas. An iatrogenic pseudoaneurysm of the anterior tibial artery had developed in the fourth patient after osteotomy of the fibula, and an iatrogenic pseudoaneurysm of the superficial femoral artery had developed in the fifth patient after erroneous puncture during venous transfemoral angiography. With a sterile technique and color duplex ultrasonographic guidance, a diluted solution of bovine thrombin was slowly injected directly into the iatrogenic pseudoaneurysms until cessation of blood flow was seen. Follow-up color duplex ultrasonography was performed 24 to 48 hours after the ultrasonographically guided thrombin injection. RESULTS: Four iatrogenic pseudoaneurysms were successfully thrombosed during 1 session. Two large iatrogenic pseudoaneurysms necessitated multiple repositions of the injecting needle and several injections of small amounts of thrombin into the residual patent lumen to induce complete thrombosis without an appreciable increase in the total thrombin dosage. Follow-up examinations revealed complete and persistent thrombosis without evidence of distal embolization. One iatrogenic pseudoaneurysm involving the cephalic vein, distal to an arteriovenous hemodialysis fistula, recurred after apparently successful initial thrombosis. CONCLUSIONS: Most iatrogenic pseudoaneurysms are amenable to ultrasonographically guided thrombin injection as long as they are imaged adequately by color duplex ultrasonography.     

超声引导下局部压迫或注射凝血酶治疗动脉插管术后假性动脉瘤的临床应用

目的探讨彩色多普勒超声引导下压迫或注射治疗假性动脉瘤的方法及疗效评估。方法 在超声引导下对20例动脉插管术后所致股动脉及锁骨下动脉假性动脉瘤患者，行压迫及注射治疗。结果14例假性动脉瘤采用单纯压迫法治疗，成功率为86％(12／14)。2例锁骨下动脉假性动脉瘤瘤内注射医用吻合胶(OB胶)，1例闭合后动脉瘤处产生硬块，另1例形成远端动脉阻塞。4例注射凝血酶者治疗成功率为100％(4／4)。结论 超声引导下对动脉插管术后假性动脉瘤采用单纯压迫法或瘤内注射凝血酶治疗是简单、安全、有效的方法，而采用瘤内注射医用OB胶则可能产生并发症。     

超声指导下冠状动脉介入术后股动脉假性动脉瘤的诊断和治疗

目的探讨超声指导下冠状动脉介入术后股动脉假性动脉瘤的发生原因、临床表现、诊断及治疗方法。方法采用超声引导下压迫修复的方法,失败的病例选择超声引导下注射凝血酶。结果经超声检查确诊冠状动脉介入术后股动脉假性动脉瘤的39例患者中有18例经压迫修复治愈,平均压迫时间（36．78±1．71）rain。21例经压迫修复失败后采用瘤腔内注射凝血酶治愈,平均瘤内血栓形成时间（0．33±0．06）min。所有患者均于修复后24h复查超声,证实假性动脉瘤已闭合。术后随诊半年,未见假性动脉瘤复发。结论冠状动脉介入术后引发股动脉假性动脉瘤,在超声引导下压迫修复和超声引导下行腔内注入凝血酶是安全有效的治疗方法。     

彩色多普勒超声诊断医源损伤性假性动脉瘤的价值

目的：探讨彩色多普勒超声在诊断冠状动脉造影术后引发的医源损伤性假性动脉瘤的临床价值。方法：经股动脉穿刺,行冠状动脉造影术而发生的股动脉假性动脉瘤共39例,所有患者都采用高频彩色多普勒诊断仪,对动脉瘤的二维超声图像、彩色多普勒图像及脉冲多普勒图像进行分析。结果：39例假性动脉瘤患者在穿刺部位动脉的一侧均显示一搏动性无回声区或混合性低回声区;彩色多普勒显示无回声区内呈涡流或旋转样血流信号,表现为一半红色一半蓝色;脉冲多普勒显示典型的双期双向频谱。39例假性动脉瘤彩色多普勒超声诊断完全明确。其中32例在彩色多普勒超声监控下行人工加压包扎修复。7例经血管外科手术修补治疗。结论：彩色多普勒超声在诊断冠状动脉造影术后造成的医源损伤性假性动脉瘤,在观察动脉瘤的大小、形态、瘤体的结构,判断来源动脉破口定位上准确、简便、无创,且可在超声引导下行安全无创治疗,可作为该病诊断及治疗的首选方法。

Ultrasonographically guided manual compression of femoral artery injuries.

To determine the success and complication rates of ultrasonographically guided manual compression in patients with femoral arterial injuries after femoral arterial catheterization, we performed 53 sonographically guided compression repairs in 51 patients. Ultrasonographically guided compression repair was performed on 40 pseudoaneurysms in non-anticoagulated patients, seven pseudoaneurysms in anticoagulated patients, four arteriovenous fistulas on non-anticoagulated patients, and one pseudoaneurysm combined with an arteriovenous fistula. One pseudoaneurysm underwent two separate ultrasonographically guided compression repairs: once when the patient was anticoagulated and once after anticoagulants were withheld. Ultrasonographically guided compression repair was successful in 37 of 48 pseudoaneurysms (77%). Of the 40 pseudoaneurysms in non-anticoagulated patients, ultrasonographically guided compression repair was successful in 36 (90%). This repair technique failed in all seven pseudoaneurysms in anticoagulated patients. Ultrasonographically guided compression repair was successful in 13 of 16 (81%) multilobulated pseudoaneurysms but failed in all arteriovenous fistulas and the one case of pseudoaneurysm combined with an arteriovenous fistula. Ultrasonographically guided compression repair is a safe and effective alternative to surgery for the repair of pseudoaneurysms, including multilobulated pseudoaneurysms. The procedure does not appear to be effective in the anticoagulated patient or in patients with an arteriovenous fistula.
