May-Thurner Syndrome ; Venous Thrombosis

May-Thurner syndrome is a deep vein thrombosis of the ilio-femoral vein due to compression of the left common iliac vein by the overlying right common iliac artery. Although, catheter directed thrombectomy (CDT) and thrombolysis with stent insertion has become the standard treatment method for acute or subacute May-Thurner syndrome, because of technical feasibility and lower recurrence rate, however, sometimes this methods make fatal complications. Furthermore, there are few reports on optimal treatment strategies for patients in a chronic state of May-Thurner syndrome,. We now present two cases of chronic (>1 month since onset of symptoms) May-Thurner syndrome treated by surgical thrombectomy and femoral arteriovenous shunt with simultaneous stent insertion after failed endovascular treatment. This technique may provide a significant benefit for patients who are not suitable for conventional endovascular treatment.

There have been a few reports on deep vein thrombosis (DVT) associated with compression of the left common iliac vein by the right common iliac artery, referred to as May-Thurner syndrome (MTS). However, there have been no reports on DVT associated with MTS in amyotrophic lateral sclerosis (ALS) patients exhibiting similar clinical features to paraplegic spinal cord injury patients. We hereby report a case of DVT associated with MTS in an ALS patient, who was treated successfully.

May-Thurner syndrome is an anatomic variant in which the left common iliac vein is compressed by the right common iliac artery. The most frequent clinical presentation is deep vein thrombosis of the left lower extremity. We report the perioperative management in a patient with May-Thurner syndrome undergoing an open reduction of a tibia fracture. The patient developed deep vein thrombosis of the left lower extremity and had an endovascular stent placed approximately 1 year earlier. An important aspect of the perioperative management in a patient with May-Thurner syndrome is to prevent deep vein thrombosis. We monitored the activated clotting time during the intraoperative period.

OBJECTIVETo evaluate the surgical techniques for acute left deep venous thrombosis (LDVT) secondary to left iliac vein compression syndrome (IVCS).

METHODSThirty-six patients with acute LDVT secondary to IVCS received inferior vena cava filter placement, and in 2 of the cases, stent implantation was canceled for acute episode of obsolete DVT. The remaining 34 patients underwent left femoral venotomy for iliofemoral thrombectomy with Fogarty catheter and distal femoral vein thrombus removal by sequential compression of the legs, followed by implantation of stent-graft (2 cases) or bare-metal stents (32 cases) in the left common iliac veins. With routine anticoagulation and thrombolytic treatments, the patients were regularly examined for postoperative blood flow in the affected limb.

RESULTSIn 2 of the cases undergoing bare-metal stent implantation, the residue thrombi were squeezed into the stent by balloon, which was managed subsequently with local thrombolysis. One patient with bare-metal stent implantation received a secondary stenting for posterior stent displacement. Three patients had self-limited bleeding due to decreased serum FBG. Significant improvements were achieved at 3, 6, 30 and 180 days postoperatively in the circumferences of the affected limb (P<0.05) and in the levels of D-dimer (P=0.011), and FBG level showed no significant variations (F=1.163, P=0.345). The total rate of excellent outcomes was 83.3% (26/34) with a total effective rate of 91.2% (31/34) in these cases.

CONCLUSIONSThrombectomy to revascularize the inflow tract and stent implantation to enlarge stenosed iliac veins are key issues in treatment of acute LDVT secondary to IVCS.

May-Thurner syndrome, compression of the left common iliac vein by the right common iliac artery, or intimal hypertrophy of the vein resulting from chronic pulsatile force of the right common iliac artery, may results in deep vein thrombosis on the left lower extremity. A patient presented to our facility with deep vein thrombosis caused by May-Thurner syndrome, and showed post-operative fever, pain, and tenderness over the left leg, showing severe lumbar disc herniation with acute cauda equina syndrome. This syndrome should be considered as one of the causes of deep vein thrombosis in the left lower extremity.

Deep vein thrombosis (DVT) is a common disease. However, May-Thurner syndrome, which is the cause of DVT, is an uncommon processes in which there is an impaired venous return due to compression of the left iliac vein by the overlying right common artery. This condition results in a left iliofemoral deep thrombosis and severe leg edema. It is, therefore, called iliac compression syndrome. Catheter-directed thrombolytic therapy of acute extensive iliofemoral DVT and balloon angioplasty with venous stenting are recommended. Two cases with history of left leg swelling are diagnosed as May-Thurner syndrome, which was demonstrated by venography. We successfully treated the patients with thrombolysis, balloon angioplasty, and stent insertion at the site of common iliac vein compression. Therefore, we report the cases with overall review of the literature.
