Objective To evaluate surgical treatment of infected pseudoaneurysm (PA) caused by injection of addictive drugs. Methods The clinical data of 17cases of infected PA caused by drug injection were reviewed retrospectively. Ofthem, 1 case was female, and the other 16 cases were male, aging 24-38 years. The locations were brachial artery in 1 case and femoral artery in 16 cases. Fourteen cases were treated by artificial blood vessel transplantation after resection of the aneurysm and radical debridement, 1 case by amputation for serious infection, and 2 cases by non-operation for different reasons. Results Among 14 cases treated by prosthetic grafts, 13 cases achieved satisfactory results, no blood drawback of lower extremity occurred after operation; 1 case had to be amputated for serious infection. After 3 months of operation, the color Doppler examination showed that the 9 artificial vessel grafts were patent and the pulse of arteria dorsal pedis was good. Conclusion Though artificial vessel grafting has high risk in the vicinity of infected PA, it is still an effective procedure for revascularization in condition that there is no suitable autogenous conduit available for auto transplantation. Sufficient drainage, anti-infection and anti-coagulation therapy should be the key factors after the operation.
Objective To compare the effectiveness, complications, and follow-up results between endovascular recanalization (EVR) and open surgical revascularization (OSR) in the treatment of peripheral pseudoaneurysm, so as to provide a reference for choosing a appropriate surgical procedure. Methods Clinical data of 62 cases of peripheral pseudoaneurysm between January 2001 and January 2012 were analyzed retrospectively. EVR was performed in 28 patients (EVR group) and OSR in 34 patients (OSR group). There was no significant difference in gender, age, cause of injury, tumor location, and diameter of tumor between 2 groups (P gt; 0.05). Results The operation time, blood loss, ICU monitoring time, and hospitalization time in EVR group were significantly shorter than those in OSR group (P lt; 0.05). In OSR group, 12 cases (35.29%) had early postoperative complications, including 2 deaths due to acute respiratory distress syndrome, 5 cases of pulmonary infection, 3 cases of wound infection, and 2 cases of deep vein thrombosis; in EVR group, 2 cases (7.14%) had early postoperative complications, including 1 case of hematoma at puncture site and 1 case of thrombosis in stent. There was significant difference in early postoperative complication incidence between 2 groups (χ2=6.691, P=0.008). The patients were followed up 12-39 months (mean, 26 months). In OSR and EVR groups after operation, the patency rates of the reconstructed vessels were 96.88% (31/32) and 92.86% (26/28) respectively at 12 months, showing no significant difference (χ2=0.014, P=0.905); the patency rates were 89.29% (25/28) and 84.00% (21/25) respectively at 24 months, showing no significant difference (χ2=0.322, P=0.570). Conclusion Compared with OSR, EVR is a minimally invasive, safe, and effective therapy for peripheral pseudoaneurysm with the advantages of less bleeding, shorter hospitalization time, and less complications. Long-term effectiveness still needs further observation, and patients have to take antiplatelet drugs for long time after EVR.
目的 探讨肢体假性动脉瘤的病因、发病机理以及手术方式的选择,评价各种手术的治疗效果,以提高对假性动脉瘤的诊治水平。方法 30例假性动脉瘤患者(股动脉18例,腘动脉7例,肱动脉2例,桡动脉3例),其中8例为感染或破裂性假性动脉瘤,1例肢体坏死。30例患者均行外科手术治疗,其中11例行假性动脉瘤破口修补术,2例行股动脉结扎术,2例行血管端端吻合术,8例行自体大隐静脉移植术,6例行人工血管移植术,1例行截肢术。结果 30例患者术后恢复顺利,除1例行下肢截肢术外,其余29例术后效果良好。随访7个月~8年,平均(4.4±2.3)年; 行人工血管移植术者4例移植段发生血栓,经溶栓治疗后好转,其余血供状况良好。结论 外科手术治疗肢体假性动脉瘤是一种有效的方法。
ObjectiveTo explore the value of modified method for intratumoral injection of thrombin in the treatment of iatrogenic pseudoaneurysms.MethodsClinical data of 28 patients with iatrogenic pseudoaneurysms after interventional treatment in our hospital from October 2012 to June 2018 were retrospectively analyzed. Twenty-one cases were treated with ultrasound-guided thrombin injection for pseudoaneurysms (Ultrasound group), and seven cases were treated with DSA-mediated balloon occlusion and thrombin injection for pseudoaneurysms (DSA group). The patients were followed-up at 1 day, 1 month and 3 monthS after operation.ResultsThe total success rates of the two groups were 100%. There was no treatment-related complications in the two groups. There was no recurrence after 1–3 months of treatment.ConclusionsIntratumoral injection of thrombin can be used for the treatment of iatrogenic pseudoaneurysm. The effect of the improved treatment is more significant. These two methods can be used as the best way to treat iatrogenic pseudoaneurysm with different neck diameters.
