Iliac vein compression syndrome: outcome of endovascular treatment with long-term follow-up

Objective

To retrospectively evaluate technical success and long-term outcome of endovascular treatment in patients with iliofemoral deep vein thrombosis (DVT) due to iliac vein compression syndrome (IVCS).

Materials and methods

Between March 2003 and September 2006, 36 consecutive patients (26 women [72%], 10 men, mean age 50 ± 18 years) with acute or chronic iliofemoral deep vein thrombosis due to iliac vein compression syndrome were evaluated for outcome of endovascular treatment. Stent patency was estimated by using the Kaplan–Meier method.

Results

Technical success was achieved in 34 of 36 patients (94%). Six patients with acute or subacute thrombosis had chronic occlusion of the left common iliac vein. Rethrombosis of the stents was observed in four patients. Primary and secondary patency rates were 85 and 94% at 1 year, and 80 and 82% at 4 years. Resolution of symptoms was achieved in 17 of 20 patients (85%) with acute and subacute DVT, and 4 of 16 patients (25%) with chronic DVT. Major complication was seen in one patient (3%).

Conclusion

Intimal changes in the left common iliac vein are mostly chronic in nature even in patients with acute DVT secondary to IVCS. Endovascular treatment with stent placement has a high technical success rate and good long-term patency in the treatment of acute and chronic DVT due to IVCS. Symptomatic improvement seems to be better in patients with acute than chronic DVT due to IVCS.     

Stents in common iliac vein obstruction with acute ipsilateral deep venous thrombosis: early and late results

PURPOSE: To evaluate, by imaging and clinical follow-up, the effectiveness and long-term results of stent placement in cases of common iliac vein obstruction associated with ipsilateral deep vein thrombosis (DVT). MATERIALS AND METHODS: Retrospective analysis of 22 patients (13 women, nine men; median age, 58 years) with common iliac vein obstruction with ipsilateral DVT was performed for this study. All patients presented with leg edema or pain and were treated with catheter-directed thrombolysis (1,000-2,000 U urokinase per kg body weight per hour; n = 19), aspiration thrombectomy (n = 21), or angioplasty (n = 14) followed by stent placement (n = 22) via an ipsilateral popliteal vein approach (right, n = 2; left, n = 20) under ultrasonographic (US) guidance. Patients were then followed by duplex US, and patency rates were determined by Kaplan-Meier survival analysis. RESULTS: The mean procedure time was 15 hours (range, 1-23 hours) and the mean urokinase dose was 1,980,000 U (range, 600,000-3,600,000 U) before the implantation of 27 stents. Three patients did not receive urokinase. The technical success rate was 96% (26 of 27 stents) and the clinical success rate was 95% (21 of 22 patients). The causes of common iliac vein obstruction were May-Thurner syndrome (n = 16), pelvic mass (n = 2), and unknown (n = 4). The early complications included upward stent migration in one patient and a spinal epidural hematoma in another. The late complication was partial stent obstruction, which was successfully treated by thrombolysis and angioplasty in one patient. Follow-up lasted 1-41 months (mean, 21.4 months). Overall, the 1-year and 2-year primary patency rates were both 95% and the 1-year and 2-year secondary patency rates were both 100%. CONCLUSION: Directed catheter thrombolysis and aspiration of DVT are relatively safe, and the use of stents improves patency results in cases of common iliac vein obstruction.     

Endovascular management of iliac vein compression (May-Thurner) syndrome

PURPOSE: To evaluate the feasibility of endovascular techniques in treating venous outflow obstruction resulting from compression of the iliac vein by the iliac artery of the left lower extremity (May-Thurner syndrome). MATERIALS AND METHODS: A retrospective analysis of 39 patients (29 women, 10 men; median age, 46 years) with iliac vein compression syndrome (IVCS) was performed. Nineteen patients presented with acute deep vein thrombosis (DVT) and 20 patients presented with chronic symptoms. All patients presented with leg edema or pain. In the acute group, patients were treated with catheter-directed thrombolysis (120,000-180,000 IU urokinase/h) and angioplasty followed by stent placement. In the chronic group, patients were treated with use of angioplasty and stent placement alone (n = 8), or in combination with thrombolysis (n = 12). Patients were then followed-up with duplex ultrasound and a quality-of-life assessment. RESULTS: Initial technical success was achieved in 34 of 39 patients (87%). The overall patency rate at 1 year was 79%. Symptomatically, 85% of patients were completely or partially improved compared with findings before treatment. Thirty-five of 39 patients received stents. The 1-year patency rate for patients with acute symptoms who received stents was 91.6%; for patients with chronic symptoms who received stents, the 1-year patency rate was 93.9%. Five technical failures occurred. Major complications included acute iliac vein rethrombosis (< 24 hours) requiring reintervention (n = 2). Minor complications included perisheath hematomas (n = 4) and minor bleeding (n = 1). There were no deaths, pulmonary embolus, cerebral hemorrhage, or major bleeding complications. CONCLUSION: Endovascular reconstruction of occluded iliac veins secondary to IVCS (May-Thurner) appears to be safe and effective.

一站式杂交手术治疗髂静脉压迫综合征合并下肢静脉曲张的疗效分析

目的：探讨一站式杂交手术治疗髂静脉压迫综合征（IVCS）合并下肢静脉曲张的临床效果及安全性。 方法：选取2013年8月至2017年7月我院收治的IVCS合并下肢静脉曲张患者91例，按照治疗方式不同分为两组：49例同期行髂静脉狭窄及曲张静脉手术（一站式杂交手术组），42例先行髂静脉成形术，二期行曲张静脉手术（分期手术组）。比较两组的临床疗效（髂静脉一期通畅率、溃疡愈合率及肿胀缓解率）、经济负担（住院天数、总费用）及安全性（并发症）。 结果：两组患者的12个月髂静脉一期通畅率（100% vs. 100%）、溃疡愈合率（100% vs. 100%）及肿胀缓解率（87.50% vs. 88.89%）差异均无统计学意义（P>0.05）；一站式杂交手术组患者的住院总费用[（3.77±0.32）万元vs.（4.37±0.20）万元]和住院天数[（13.50±2.30）d vs.（16.61±3.28）d]均低于分期手术组，差异有统计学意义（t=-9.52、-4.62，P均<0.01）；两组的并发症主要为腹股沟区出血及皮下大面积淤血，并发症发生率差异无统计学意义[6.12%（3/49）vs. 4.76%（2/42），P>0.05）]，予以相应处理后均好转；两组均无下肢深静脉血栓形成、肺栓塞及支架内血栓形成发生。 结论：IVCS合并下肢静脉曲张行一站式杂交手术治疗，近期疗效好，具有微创、住院时间短、总费用低等优点，值得临床推广开展。     

Mechanical thrombectomy of acute iliofemoral deep vein thrombosis with use of an Arrow-Trerotola percutaneous thrombectomy device

PURPOSE: To evaluate the immediate and 1-year clinical outcomes of mechanical thrombectomy with use of the Arrow-Trerotola percutaneous thrombectomy device (PTD) with or without low-dose urokinase in the treatment of acute iliofemoral deep vein thrombosis (DVT). MATERIALS AND METHODS: Mechanical thrombectomy with the PTD was performed in 25 patients with acute iliofemoral DVT. Thrombolytic therapy with low-dose urokinase was used in all patients without contraindications (n = 20). Other therapies used in combination included inferior vena cava filter insertion (n = 5), sheath aspiration thrombectomy (n = 25), and angioplasty and stent placement (n = 20). RESULTS: Initial technical and clinical success was achieved in all cases. In the 20 patients who had no contraindications to the use of urokinase, the dosage of urokinase did not exceed 1 million IU (range, 360,000-1,000,000 IU; mean, 640,000 IU). The mean time of urokinase infusion was 16 hours (range, 12-20). In five patients who had a contraindication to the use of urokinase, mechanical thrombectomy with the PTD was successful without the use of urokinase. There were no major complications. Primary patency of the stent-implanted common iliac vein segment was achieved at 1 year in 17 of 20 patients (85%). The overall 1-year clinical success rate was 92% (23 of 25 patients). Valvular insufficiency occurred in two patients (8%). CONCLUSION: The PTD is an effective mechanical thrombectomy device in the treatment of acute iliofemoral DVT with or without adjunctive urokinase thrombolysis.     

Ultrasonographic diagnosis of iliac vein compression (May-Thurner) syndrome

Iliac vein compression syndrome (IVCS), also known as May-Thurner syndrome, is the result of compression of the left common iliac vein between the right common iliac artery and overlying vertebrae. The most common clinical presentation is left lower extremity deep vein thrombosis. Rarely, a patient with IVCS can present with obstruction of venous outflow, without deep vein thrombosis. Iliac vein compression, with or without thrombosis, should be treated if symptomatic. We present a patient with IVCS that was initially diagnosed with transabdominal ultrasonography (US), and then confirmed with computed tomography and venography with pressure measurements. We believe this is the first report of an IVCS patient diagnosed with US.     

Compression of the left common iliac vein in asymptomatic subjects and patients with left iliofemoral deep vein thrombosis

PURPOSE: To retrospectively evaluate compression of the left common iliac vein as demonstrated at computed tomography (CT) in patients with iliofemoral deep vein thrombosis due to iliac vein compression syndrome (IVCS) and compare compression ratios with those of asymptomatic subjects. MATERIALS AND METHODS: Between March 2003 and June 2007, compression of the left common iliac vein by the right common iliac artery, as demonstrated with CT, in 34 patients (25 women and nine men; mean age, 51 years; age range, 21-79 years) with IVCS was retrospectively evaluated. Compression ratios were compared with those of 34 age- and sex-matched asymptomatic subjects. A t test was used to compare the compression ratios. RESULTS: The percentages of compression of the left common iliac vein were 45%-100% (mean, 74% +/- 17) for patients with IVCS and 0%-68% (mean, 28% +/- 20) for control subjects (P < .05). Of the 34 patients with IVCS, 11 (32%) had less than 70% compression and 23 (68%) had at least 70% compression. CONCLUSIONS: There was considerable overlap between the degree of compression in patients with IVCS and control subjects. Compression of the left common iliac vein was significantly more prominent in patients with lower extremity deep vein thrombosis due to IVCS when compared with control subjects. Compression in excess of 70% as demonstrated at CT can be helpful for identifying possible underlying IVCS in patients with a left lower extremity deep vein thrombosis.
