A 59-year-old man with critical claudication underwent left femoro-anterior bypass grafting, which was uneventful. The graft was tunneled medially across the knee, then anterior to the tibia. His symptoms recurred 1 year later and he was found to have critical stenosis of the vein graft just proximal to the anterior tibial arterial anastomosis. This was treated with scaffolded balloon angioplasty and implantation of a coronary, zotarolimus-eluting balloon-expandable stent, which was also uneventful. However, his claudication again recurred 1 year later...

Ankle arthroscopy carries a lower risk of vascular complications when standard anterolateral and anteromedial portals are used. However, the thickness of the fat pad at the anterior ankle affords little protection for the thin-walled anterior tibial artery, rendering it susceptible to indirect damage during procedures performed on the anterior ankle joint. To our knowledge, only 11 cases of pseudoaneurysm involving the anterior tibial artery after ankle arthroscopy have been described in the literature. Here we reported a rare case of a 19-year-old soccer player who presented with pseudoaneurysm of the anterior tibial artery following ankle arthroscopy using an ankle distraction method and underwent anastomosis for the anterior tibial artery injury...

Our previous study indicated that interleukin (IL)-37 is involved in atherosclerosis. In the present study, Anterior tibial arteries were collected from diabetes patients and controls. A histopathological analysis showed that IL-37 was over-expressed in human atherosclerotic plaques. Many types of cells including macrophages, vascular smooth muscle cells (VSMCs), endothelial cells and T lymphocyte expressed IL-37 in human atherosclerotic plaques. ApoE-/- mice were divided into a control group and a recombinant human IL-37-treated group...

INTRODUCTION: Trophic disorders of the extremities are a common complication of systemic sclerosis (SSc), mainly related to microvascular damage. However, SSc seems to be a risk factor for premature athero-thrombotic disease that can affect the peripheral arteries, participate in the occurrence of trophic disorders and promote the occurrence of infectious complications. The objective of this study was to assess the prevalence of arterial disease of the limbs in SSc patients. METHODS: Consecutive inclusions in the context of a multidisciplinary consultation centered on disability of the hand with collection of clinical data [cardiovascular risk factors (CVRF), history of trophic disorders of ischemic origin, peripheral pulse palpation, Allen maneuver the upper (UL) and lower limbs (LL)], and hemodynamic data (flow recorded by Doppler in radial, ulnar, anterior and posterior tibial arteries, and measurement of systolic indices ankles)...

Vascular calcification is established to be a critical factor in diabetes mellitus, which causes cardiovascular and amputation complication of diabetic patients. OPG/RANKL/RANK axis serves as a regulatory role in vascular calcification. Ghrelin, an endogenous ligand of growth hormone secretagogue receptor (GHSR), has been reported to exhibit potent cardiovascular protective effects. However, the role of ghrelin in the regulation of diabetic vascular calcification is still elusive. Here, we reported the role of ghrelin and its relationship with OPG/RANKL/RANK system in patients with diabetic foot amputation...

BACKGROUND: Approximately 20% of patients undergoing ankle brachial index testing for critical limb ischemia have noncompressible vessels because of tibial artery calcification. This represents a clinical challenge in determining tibial artery patency. We sought to identify the prevalence of tibial artery and pedal arch patency by angiography in these patients. METHODS AND RESULTS: One hundred twenty-five limbs (of 89 patients) with critical limb ischemia and ankle brachial index ≥1...

Anterior arthroscopic tibiotalar arthrodesis has been well codified. A posterior approach with the patient in prone position is indicated when the anterior approach is precluded by soft tissue issues or for a 1-step procedure associated with posterior subtalar fusion. In an anatomic study, we assessed the feasibility of posterior arthroscopic tibiotalar fusion and sought to determine the arthroscopy entry points, mortise cartilage freshening quality, and risk of osseous, tendinous, vascular, and neural complications...

BACKGROUND: Antiphospholipid syndrome (APS) is a condition that manifests as venous or arterial thrombosis, as well as complications of pregnancy. APS affecting primarily the arteries is less common when compared to venous complications. We present a case of arterial occlusion resulting in critical limb ischemia (CLI) in a pediatric patient. METHODS: A 14-year old boy presented with worsening right lower extremity pain and ulcerative lesions of his foot. Laboratory analysis revealed a diagnosis of APS...

We present the case of a patient with a history of aortobifemoral grafting who presented with left lower extremity ischemic rest pain. Aortofemoral angiography was performed through a left radial access and showed a long, calcified total occlusion of the left superficial femoral artery (SFA) and a subtotal popliteal occlusion. The popliteal artery and SFA were crossed retrogradely through a 4-Fr anterior tibial access; the retrograde devices went subintimally and did not reenter at the common femoral level...

Vascularized free fibula transfer remains the gold standard for reconstruction of large segmental diaphyseal defects of the upper extremity. In the pediatric patient, before skeletal maturity, free fibula transfer with the fibular head provides an active physis for growth and an articular interface for glenohumeral joint reconstruction. Clinical and cadaveric studies have demonstrated that the vascular supply to the fibular head originates, in most cases, from the anterior tibial system. However, anatomical variation exists, and we report a case in which a vascularized fibula autograft including the physis was transferred on the peroneal artery in a 5-year-old patient with Ewing's sarcoma...

BACKGROUND: The evaluation and treatment of heel pressure injuries are a significant and expensive sequela of the aging population. Although the workup of patients with lower extremity tissue loss usually involves an assessment of the arterial blood flow by means of noninvasive vascular testing, the results may be misleading in patients with heel pressure injuries when the ankle-brachial index (ABI) does not provide direct information about perfusion of the rearfoot. The objective of this retrospective, observational investigation was to determine if noninvasive vascular testing provides accurate and reliable results in patients with heel pressure injuries...

Although the foot and ankle derives its arterial supply from a combination of the anterior tibial artery (ATA), posterior tibial artery (PTA), and peroneal artery (PA), the focus of clinical examination techniques and noninvasive vascular testing is primarily on the ATA and PTA and not on the PA. The objectives of the present investigation were to evaluate the feasibility of incorporating an assessment of the PA into a noninvasive vascular testing protocol and to collect normative data of pressure measurements of the PA at the ankle...

Pure ankle dislocation is a rare event that primarily results from high-energy trauma. Predisposing anatomical factors such as talar hypoplasia, ligament laxity, and previous sprains may play a key role. This report presents the case of a 55-year-old man with fatal anterior and posterior tibial artery tears following a pure anterolateral dislocation of the right ankle. To the best of our knowledge, no such cases have previously been reported in the English-language literature.

PURPOSE: To determine the frequency of popliteal artery branching variations in a wide study cohort and to investigate the relationship between these variations and infrapopliteal peripheral arterial disease (PAD). A subclassification was proposed for the most encountered type I-A, utilizing tibio-fibular trunk (TFT) length. METHODS: A total number of 1184 lower extremity digital subtraction angiography (DSA) studies of 669 patients were evaluated. Following exclusion, 863 lower extremity DSA studies (431 right, 432 left) of 545 patients were enrolled...

BACKGROUND: In total knee arthroplasty, it is better to use more than one reference point for correct alignment of the components. By measuring the distances of Achilles tendon (AT) and other conventional landmarks from the mechanical axis in magnetic resonance imaging (MRI) of the ankle, we aimed to demonstrate that, as a novel landmark which can help for correct alignment in the coronal plane, AT is a better option than other landmarks. MATERIALS AND METHODS: This retrospective study was done on 53 ankle MRIs that met the criteria for inclusion to the study among 158 ankle MRIs...
