Patients were compared according to type of revascularization: limited to AI vs. AI+II. Common femoral and profunda artery endarterectomy (C/P-TEA) was considered in both groups. Perioperative mortality, limb salvage, foot healing (within 6 months after surgery), necessity of adjunctive revascularization and survival were analyzed and the follow-up performed with clinical and duplex assessment every six months.

AI revascularization was performed in 38 (40%) and AI+II in 58 (60%). AI and AI+II groups were similar for preoperative risk factors and extension of PAD with the exception of American Society of Anesthesiology (ASA) Classification (ASA IV: 50% vs. 25%, P=0.02, respectively). The AI group was treated with angioplasty/stenting in all cases and with C/P-TEA in 20 (52%) cases. In the AI+II group, the AI district was treated by angioplasty/stenting in 55 (95%) and by aorto-bifemoral bypass in 3 (5%) and C/P-TEA in 20 (34%). The II revascularization was performed by femoro-popliteal/tibial bypass in 27 (47%); and endovascular revascularization in 31 (53%) patients. Minor amputation rate was similar between AI and AI+II revascularization (39% vs. 48%, P=1.0); length of stay, blood transfusion units, were significantly higher in AI+II group: 7±4 days vs. 12±5 days, P=0.04 and 2±2 vs. 4±2, P=0.02. The 30-day mortality was 7% with no differences according to the type of treatment. At a mean follow-up of 28±10 months, the overall limb salvage was 87±4% with similar results in AI vs. AI+II revascularization (95±5% vs. 86±6%; P=0.56). AI had a higher necessity of adjunctive revascularization and lower wound healing compared to AI+II (18±9% vs. 0%, P=0.02; 72% vs. 100%, P=0.001, respectively).

Besides deteriorated blood flow caused by VVs inflammation is most probably a common denominator of VVs and DVT, which promotes a procoagulant state and thrombus formation also in deep veins. Patients with VVs have increased levels of interleukins, the most specific inflammatory markers of vascular wall inflammation that promote coagulation. The studies showed that VVs may increase the risk for DVT. However, the evidence of the risk and incidence of DVT in patients with VVs and without additional risk factors is poor. The increased risk is associated with previous venous thromboembolism (VTE), malignancy, estrogen use, pregnancy and postpartum, hospitalization in the last 6 months, age, and obesity. Varicose veins represent also an increased risk for VTE during long-term immobilization and long air travel or road trip. Further, superficial venous thrombosis is related to an increased risk for DVT, particularly if the thrombus in the superficial vein extends close to the saphenofemoral or femoropopliteal junction.
