“…In our study, no significant difference was noted between the two the right common iliac artery and vertebra because spurs did not contain elastic fiber and hemosiderin, capillary blood vesselrich collagen tissue was more or less contained, lymphocyte infiltration was observed, and elastic fibers of the tunica media were distributed along the venous wall and localized on the spur surface, not entering spurs. Ehrich, et al 11) , Negus, et al, 13) and DiDio 17) support this theory. As described in Results, there was histological vari ation in the spur structure.…”

Histological Study on the Left Common Iliac Vein Spur

The spur occasionally seen in a left common iliac vein was investigated by anatomical and histological examination of cadavers so the occurrence mechanism could be discussed. Spurs were found in six cases of the 28 cadavers (21.4%) and they were classified into few different kinds of composition of endosporia, tunica media and adventitia. It is considered that there may be different formation mechanisms and stages even in cases of similar anatomical finding. (*English translation of J Jpn Coll Angiol 2013; 53: 43-47)

Purpose: May-Thurner syndrome (MTS) is a rare clinical entity featuring venous obstruction of the left lower extremity. The aim of the present study was to report our experience with MTS and to evaluate the utility of treatment using endovascular techniques. Materials and Methods:We retrospectively analyzed data on 23 MTS patients (21 females, two males; mean age 44 ± 15 years). Eighteen patients presented with deep vein thrombosis (DVT) and fi ve with symptoms associated with chronic venous hypertension (CVH). DVT patients were treated via thromboaspiration, catheter-directed thrombolysis, and angioplasty; followed by stent placement. CVH patients were treated with angioplasty and stent placement alone. All patients were followed-up using Doppler ultrasonography and computed tomography venography. Results: Complete left common iliac vein patency was achieved in 21 of the 23 patients (technical success rate: 91,3%). Complete thrombolysis was attained by 14 of the 18 DVT patients (77.7%). The mean clinical and radiological follow-up time was 15.2 ± 16.1 months. Upon follow-up, complete symptomatic regression was observed in 19 of the 23 patients (82.6%). Stent patency was complete in 19 of the 21 patients (90.4%) who received stents. Restenosis occurred in two patients. No treatment-related mortality or morbidity was observed. Conclusion: Endovascular treatment of MTS is safe and effective and reduces symptoms in most patients, associated with high medium-term patency rates.

“…As May-Thurner syndrome is a chronic process with development of permanent venous wall lesions and intraluminal spurs (2)(3)(4), the degree of stenosis should not change significantly over time, specifically between the index study and the comparison study. In our study, we found that the mean change in the degree of LCIV compression was 23.1%, which ranged from an 11.7% increase to a 68.8% decrease in degree of compression.…”
