Abstract：

Objective To evaluate a combination of open surgery and multiple interventional methods in the treatment of DVT of the lower extremities. Methods 521 cases (521 limbs,356 male and 165 female) were studied in this group. Age ranged from 16 to 86 years with the mean age of (46 ±9)years. All 521 cases with DVT were treated by Fogarty embolectomy catheter. Among them,348 cases underwent percutaneous transluminal angioplasty (PTA), 135 cases received PTA and ultrasound ablation,stent-grafts were implanted in 108 cases. Results Based on angiography during operation, the obstructed iliofemoral vein received complete recanalization in 511 cases. Among them, the postoperative luminal diameter was more than 90% in 38 cases after Fogarty embolectomy, the average stenosis rate was reduced from 90% ±5% to 24% ±5% in 365 cases after PTA and stent-grafts were implanted in 108 cases with the stenosis rate still over 50% after PTA. Only partial recanalization was achieved in the entrance of common iliac vein to inferior vena cava in 10 cases. Of the 521 cases,472 cases were followed-up with mean time of (53 ± 26) months, ranging from 8 to 108 months and 462 cases reported satisfactory results with normal life,the unsuccessful 10 cases still felt swelling pain especially in erect position. Complications occurred in 33 cases. Conclusions Open surgery combining with multiple interventional methods is a safe and effective method in the treatment of DVT.     

急性下肢深静脉血栓形成局部置管溶栓与外周静脉溶栓的比较

Objective To investigate the efficacy of anticoagulation and thrombolysis for deep venous thrombosis via local vein approach and peripheral vein approach to guide clinical treatment. Methods There were 225 patients with deep venous thrombosis admitted from January 2001 to May 2008. The cases were divided into two groups by therapy procedures. The patients in group A were treated by deep femoral vein catheter-directed anticoagulation and thrombolysis, including a total number of 71 patients, with right lower extremity in 20 patients, left lower extremity in 47 patients and bilateral lower extremities in 4 patients. One hundred and fifty-four patients were included in group B with anticoagulation and thrombolysis through peripheral vein, among them right lower extremity in 27 patients, left lower extremity in 121 patients and bilateral lower extremities in 6 patients. The efficacy was evaluated and compared by observing clinical symptoms and measuring of changes in limb circumference. Results Symptoms were alleviated in all patients in 3 d after the treatment, but the efficacy of group A was better than group B (94. 4% vs. 69. 5% ,P＜0. 01). The efficacy of group A was also better than group B in 7 days after treatment, but with no significant difference (85. 9% vs. 75. 3% , P ＞0. 05). A mean follow-up period was (43 ±18) months.There was no significant difference in incidence of complication and recurrence between two groups.Conclusions The earlier efficacy of anticoagulation and thrombolysis via femoral vein approach is better than via peripheral vein approach in earlier period of deep venous thrombosis. While peripheral intravenous therapy has also good results after long-term treatment.

Abstract：

Objective To present clinical results of endovascular treatment of total iliac vein occlusions and to discuss the technique details of this treatment. Methods From Feb 2006 to Aug 2010,15 patients with chronic total occlusive lesions of the iliac vein and adjacent vein segments underwent endovascular treatment. Average age was (62 ±7) years (range 35 to 81 years), the male/female ratio was 12: 3. Clinical score of CEAP was grade 3 in 33. 3%, grade 4 in 40%, grade 5 in 13. 3%, and grade 6 in 13.3%. Venography showed left iliac vein was occluded in all 15 patients, common femoral vein was occluded in 14 patients, and superior femoral vein was occluded in 9 patients, however profounder femoral vein was patent in these patients with superior femoral vein being occluded. Results No postoperative major morbidity or mortality was seen. The technique success rate was 93. 3%. Treatment failure was caused in one case for a wrong selection of the femoral vein approach site. The average length of stent was 18. 4 cm.In 12(80. 0% ) stents crossed the inguinal ligament. The average follow-up time was 11.6 ± 2. 4 months.The primary patency rates of the stents at 6 months were 92. 9%. 10 (66. 7% ) patients were asympotomatic, 3(20% )were improved, 1 (6. 7% ) was unchanged, and 1 (6.7%) was worse, compared to before intervention. Conclusions Endovscular recanalization and stent placement is a safe and effective treatment for chronic total occluded iliac veins, with good patency, significant symptom resolution, and minimal morbidity in the short term follow-up.

Endovaskuläre Behandlung akuter und chronischer Beckenvenenverschlüsse

In the past, open surgical techniques such as thrombectomy and bypasses were the treatments of choice for acute and chronic venous occlusive disease of the iliocaval vein segments, but the results were often disappointing. With the introduction of endovascular techniques in the 1990s, open techniques were widely replaced by endovascular interventions. Proper preoperative imaging with computed tomography and magnetic resonance phlebography has become an important part of procedure planning, but phlebography by direct puncture with contrast injection in the immediate proximity of the iliofemoral segment is still the most informative diagnostic method. Catheter-directed thrombolysis with recanalization and stenting of underlying chronic obstructions is becoming the treatment of choice for patients with acute iliofemoral thrombosis, as conservative treatment is not satisfactory for preventing postthrombotic syndrome. Recanalization of chronic iliac vein occlusions with balloon angioplasty and stenting can reestablish normal venous flow in the iliac veins and inferior vena cava and relieve symptoms in the majority of treated patients. New treatment modalities offer stimulating options for patients not treated adequately either by medical or open surgical therapy.     

Surgical thrombectomy followed by intraoperative endovascular reconstruction for symptomatic ilio-femoral venous thrombosis.

OBJECTIVES: To evaluate the efficacy of surgical thrombectomy combined with endovascular reconstruction for acute ilio-femoral/caval venous thrombosis. METHODS: Twenty consecutive patients with acute, symptomatic ilio-femoral/-caval thrombosis underwent valve-preserving thrombectomy with immediate endovascular repair between October 1996 and October 2003. Thrombectomy was classified by intraoperative venography as: TYPE I=complete, TYPE II=partial, TYPE III=complete with stenosis other than thrombus, TYPE IV=permanent occlusion. TYPEs I and IV were excluded from this analysis because endovascular repair was not performed. RESULTS: Left-sided venous thrombosis predominated (90%). Lesions were located in the common iliac vein (85%), the external iliac vein (10%), and the inferior vena cava (5%). Three TYPE II lesions and 17 TYPE III lesions (11 spurs, one hypoplasia, one fibrosis, one haematoma, and three others) were diagnosed. Catheter-directed recanalisation (thrombectomy/thrombolysis) resolved TYPE II lesions in three patients. Balloon angioplasty (one patient), iliac stenting (15 patients [two with thrombolysis]), and caval stenting (one patient) were employed in TYPE III stenoses. No serious complication or death occurred. Mean follow-up was 21 months. Of 20 patients clinical results were excellent in 18 patients who maintained patency of their reconstructed iliac veins. Primary and secondary patency rates were 80 and 90%, respectively. CONCLUSIONS: Ilio-caval venous obstructions detected intraoperatively can be reconstructed in a one-stage combined procedure. The specific endovascular approach depends on the type of residual venous obstruction. Excellent mid-term results indicate that the proposed thrombectomy classification (TYPE I-IV) and treatment algorithm optimises the results in selected patients with symptomatic venous thrombosis.

背景与目的 下肢深静脉血栓形成（DVT）行早期血栓清除减容可恢复静脉通畅及缓解症状,目前AngioJet是国内最常用的静脉血栓清除系统,而Aspirex应用较少,本研究探讨Aspirex机械血栓清除治疗在创伤后急性DVT患者中的疗效及安全性。方法 回顾性分析2016年5月—2020年8月在北京积水潭医院血管外科收治的54例创伤后急性DVT患者的病例资料。所有患者行下腔静脉可回收滤器置入术,其中有Dneali 35例（64.8%）、Celect 3例（5.6%）、Cordis 14例（25.9%）、Octoparms及临时滤器（贝朗）各1例（1.9%）。患者创伤经手术及固定治疗后均行彩超检查或造影明确为髂股静脉及下腔静脉血栓形成。其中,22例（40.7%）为髂股静脉血栓、4例（7.4%）为髂及下腔静脉血栓、11例（20.4%）为下腔静脉血栓、17例（31.5%）为股髂静脉及下腔静脉血栓。所有患者在局麻下行经腘静脉或股静途径Straub Aspirex机械血栓清除手术（PMT）,术中联合导管取栓（MAT）、导管接触性溶栓（CDT）、髂静脉球囊扩张及髂静脉支架置入术。统计技术成功率、即刻临床成功率（症状缓解率）、围手术期出血发生率及术后滤器取出率。术后随访1年,超声评价目标静脉通畅率及血栓后综合征（PTS）的发生率。结果 54例患者中,3例（5.6%）行单纯机械血栓清除手术,17例（31.5%）行血栓清除联合导管取栓术,3例（5.6%）行血栓清除联合置管溶栓术,18例（33.3%）行血栓清除联合导管取栓及置管溶栓术,12例（22.2%）行血栓清除联合导管取栓及髂静脉球囊扩张术,1例（1.9%）行血栓清除联合导管取栓及支架置入术。技术成功率及即刻临床成功率均为100%。12例（22.2%）血栓III级清除,33例（61.1%）为II级清除,9例（16.7%）为I级清除,血栓清除成功率为83.3%。围手术期1例（1.9%）出现脑出血,给予停止溶栓及抗凝,2周复查头颅CT见血肿吸收,无后遗症;2例（3.7%）出现鼻出血及穿刺点血肿,给予压迫后缓解,无症状性肺栓塞及死亡等发生。滤器留置时间为（61.4±84.8）d,51例（94.4%）患者尝试行滤器取出,所有患者均成功取出。术后无血栓复发,术后1年PTS的发生率为33.3%,目标静脉通畅率为75.9%。结论 对于创伤后急性髂股及下腔静脉DVT患者,应用Aspirex机械血栓清除疗效显著,较为安全可靠,与导管吸栓、CDT、髂静脉球囊扩张及支架置入结合应用可改善静脉通畅率。     

Treatment of May-Thurner syndrome with catheter-directed thrombolysis and stent placement, complicated by heparin-induced thrombocytopenia.

May-Thurner syndrome is an uncommon process in which the right common iliac artery compresses the left common iliac vein, resulting in left iliofemoral deep vein thrombosis and severe leg edema. We report the case of a 41-year-old female who presented with severe left leg edema present for 1 day. One week earlier she had experienced acute shortness of breath and pleuritic chest pain. Duplex ultrasound revealed a left iliofemoral deep vein thrombosis. A computed tomography (CT) scan performed for abdominal pain revealed thrombosis of the entire left common and external iliac veins. A ventilation-perfusion scan diagnosed a pulmonary embolism. The patient was treated with systemic intravenous heparin and catheter-directed thrombolysis of the iliofemoral deep vein thrombosis. Complete thrombolysis and iliofemoral vein patency was achieved over 5 days. A persistent stenosis in the left common iliac vein consistent with May-Thurner syndrome was alleviated with percutaneous balloon angioplasty and placement of a Wallstent. Heparin therapy was terminated at the time of stenting because of suspected heparin-induced thrombocytopenia. The patient was started on a continuous infusion of 10% dextran 40, and warfarin therapy was initiated. Heparin-induced antibodies were confirmed by a C-14 serotonin release assay. The endovascular reconstruction remains patent 4 months later. Heparin-induced thrombocytopenia complicating endovascular reconstruction of the iliofemoral venous system in a patient with May-Thurner Syndrome is an uncommon occurrence. This case and a review of the literature are discussed.     

Radiation-associated venous stenosis: endovascular treatment options

We report a case of radiation-induced venous stenosis after pelvic irradiation to treat Paget's disease of the scrotum. During therapeutic anticoagulation, significant left lower extremity swelling developed due to an iliofemoral deep venous thrombosis (DVT). After percutaneous thrombectomy and thrombolysis, a high-grade stenosis was uncovered in the left external iliac vein, which was treated with an endoluminal stent. However, ipsilateral DVT recurred 2 months later despite continued anticoagulation therapy. Repeat treatment was successful. Pelvic radiation is a potential cause of iliac vein stenosis. Pharmacomechanical thrombectomy may have a useful role in management of complex iliofemoral DVT.
