BACKGROUND: A common method for reconstruction of the anterior cruciate ligament (ACL) is it's replacement by a free avascular graft, using the gracilis and/or semitendinosus tendons. These grafts pass a vulnerable phase in the ligamentization-process during the 1(st) year after reconstruction. The aims of this study were first to evaluate the vascularization of the pes anserinus superficialis (PAS) by the inferior medial genicular artery (IMGA) and second to develop a pedunculated surgical technique for ACL reconstruction, to preserve a maximal amount of natural vascularization of the tendons inserting at the PAS...

PURPOSE: The aim of this work was to evaluate the long-term patency of endo-grafting in the treatment of popliteal artery aneurysms (Paa) and to identify which factors may be predictor of graft occlusion. METHODS: All the patients that underwent endovascular repair of Paa were analyzed from 2006 until 2014 on the basis of symptoms, comorbidities, limb salvage and long-term patency. The predictive value of the different variables was assessed in univariate analysis for primary patency and, for factors resulted significant, a multivariate analysis was performed...

OBJECTIVES: An occluded lower limb arterial bypass is associated with poor prognosis for the limb. Currently, no risk assessment method to estimate the risk of early graft failure exists. Aim of this study was to investigate the effect of various potential factors on early graft failure of infrainguinal bypass surgery and to develop a risk-scoring model to predict it. DESIGN AND METHODS: A prospective observational clinical study was performed. One hundred infrainguinal bypass procedures (60 autologous and 40 synthetic grafts), throughout a 3-year period were included...

Venous thromboembolism (VTE) includes deep vein thrombosis (DVT) and/or pulmonary embolism (PE). Many surgeons and clinicians believe that VTE after coronary artery bypass grafting (CABG) has little clinical significance because it is seldom diagnosed. This study aimed to identify VTE after CABG, independent of clinical suspicion. In this prospective, observational, single-center study, 100 patients underwent computed tomographic pulmonary angiography (multidetector-64) and lower extremity venous compressive ultrasound after elective CABG...

Monocytes are mononuclear cells characterized by distinct morphology and expression of CD14 and CD16 surface receptors. Classical, quiescent monocytes are positive for CD14 (lipopolysaccharide receptor) but do not express Fc gamma receptor III (CD16). Intermediate monocytes coexpress CD16 and CD14. Nonclassical monocytes with low expression of CD14 represent mature macrophage-like monocytes. Monocyte behavior in peripheral arterial disease (PAD) and during vessel wall directed treatment is not well defined...

Aim. To raise the awareness of a hypercoagulability state as it is often associated with the different types of malignancies. Venous thromboembolism is a frequent complication in these patients, and usually it happens after the diagnosis of cancer is confirmed. However, hypercoagulability disorders presenting as the first symptoms or signs in the cancer patients have rarely been reported. Furthermore, arterial thrombosis is extremely rare even in cancer patients. Method. Review of the case characteristics and literature review...

Blood-oxygen-level-dependent magnetic resonance imaging (BOLD MRI) has the potential to quantify skeletal muscle oxygenation with high temporal and high spatial resolution. The purpose of this study was to characterize skeletal muscle BOLD responses during steady-state plantar flexion exercise (i.e., during the brief rest periods between muscle contraction). We used three different imaging modalities (ultrasound of the popliteal artery, BOLD MRI, and near-infrared spectroscopy [NIRS]) and two different exercise intensities (2 and 6 kg)...

INTRODUCTION AND OBJECTIVES: Tibioperoneal occlusive disease is one of the most difficult disease processes to successfully treat. Previous studies have attempted to address the outcomes of tibial interventions in this patient population; however, the majority of these study cohorts are composed of patients who have undergone concomitant aortoiliac or femoral procedures. Our objective was to present the outcomes of patients treated with endovascular intervention for isolated below-the-knee atherosclerotic disease causing critical limb ischemia (CLI)...

Osteochondroma is the most common benign skeletal tumour. It frequently causes pain and local symptoms, however, vascular complications are rare. The popliteal artery is more commonly affected and there are isolated case reports of popliteal artery pseudoaneurysm in literature. However, venous complications are extremely rare. We hereby report a case of 21-year-old male patient with distal femoral osteochondroma complicated by a popliteal venous aneurysm and deep vein thrombosis. This association has not been described in the past...

Livedoid vasculopathy (LV) is a chronic disease with recurrent reticularis and ulcers, mainly affecting the feet and lower legs. The pathogenesis of LV has not been yet thoroughly understood, but thrombosis is thought to play a major role because fibrin deposition within both the wall and lumen of affected vessels is pathologically detected. A 68-year-old woman first presented to our hospital in 2004 with a 6-year history of a reticular rash and ulceration on the lower legs. Screening tests for vasculitis and collagen disease were mostly normal, leading to diagnosis of LV...

INTRODUCTION: The saphenous vein is commonly used as a vascular graft in peripheral artery surgery but rarely used for vascular access. The literature on straight configuration saphenous vein transposition to the popliteal artery is scarce. Here we present two cases of straight configuration saphenous vein transposition to the popliteal artery for vascular access, the surgical technique and respective follow-up. CASE REPORT: Two young men, aged 29 and 36 years, were chosen for lower-limb vascular access for hemodialysis...
