    Objectives: Carotid artery stenosis (CAS) and vertebral artery stenosis (VAS) are associated with cerebral infarction after coronary artery bypass graft surgery (CABG). It remains unclear whether this association is causal. We investigated the associations between neurologically asymptomatic CAS and VAS and the occurrence of subclinical cerebral lesions after CABG verified by magnetic resonance imaging.Methods: CABG patients were included and CAS and VAS were identified by magnetic resonance angiography. Cerebral magnetic resonance imaging was performed to identify new post-operative subclinical cerebral lesions. The associations between CAS/VAS post-operative cerebral lesions were investigated.Results: Forty-six patients were included in the study. 13% had significant CAS and 11% had significant VAS. Thirty-five percent had new cerebral infarction postoperatively. We found a significant association between the presence of cerebral vessel stenosis and acute cerebral infarction (67% vs. 27%, p = 0.047). However none of the patients with stenosis had isolated cerebral lesions in the ipsilateral vascular territory.Conclusion: Asymptomatic CAS and VAS is common in CABG patients and is associated with an increased risk of postoperative cerebral infarction. Our study suggests that asymptomatic CAS and VAS primarily are risk markers rather than causal factors for cerebral infarction after CABG.

    Objective: This study was designed to investigate our long-term experience with combined iliac endovascular therapy (EVT) and infrainguinal bypass to treat critical limb ischemia (CLI) and compare outcomes to those of patients who underwent surgery for aortoiliac lesions.Materials and Methods: From April 2000 to June 2013, 57 patients (58 limbs) underwent an infrainguinal bypass combined with aortoiliac reconstruction to treat CLI. Eighteen limbs were treated by bypass alone and 8 limbs were treated by bypass with EVT for aortoiliac lesions (Bypass group). Thirty-two limbs were subjected to EVT alone for iliac lesions (EVT group).Results: Preoperative limb ischemia was more severe in the EVT group. There were no significant differences in major procedure-related complications (χ2 test, P = 0.853), systemic complications (P = 0.853), and mortality (P = 0.916) between the 2 groups. The limb salvage rates were 92% at 1, 3, and 5 years in the Bypass group and 93% at 1, 3, and 5 years in the EVT group, with no significant difference observed between the groups (Kaplan-Meier, log-rank test, P = 0.616).Conclusion: Infrainguinal surgical reconstruction combined with an iliac EVT is an acceptable strategy for managing patients with CLI.

    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 five 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.
