Aim The rapid hyperaemia evoked by muscle compression is short-lived and was recently shown to undergo a rapid decrease even in spite of continuing mechanical stimulation. The present study aims at investigating the mechanisms underlying this attenuation which include local metabolic mechanisms, desensitization of mechano-sensitive pathways, and reduced efficacy of the muscle pump. Methods In 10 healthy subjects short sequences of mechanical compressions (n=3-6; 150 mmHg) of the lower leg were delivered at different inter-stimulus intervals (ranging from 20 to 160 s) through a customized pneumatic device...

Mechanochemical ablation (MOCA) is a nonthermal nontumescent technique used in the treatment of superficial venous disease. This review analyzed the available data on the efficacy and safety of MOCA. A systematic literature search was performed. Of 101 studies identified, 14 were suitable for inclusion. The studies were found to be heterogeneous in design, and the quality of evidence was found to be low or very low. MOCA was demonstrated to be effective in the short-term with minimal complications. Consensus guidelines and definitions of reporting outcome measures must be standardized to allow comparison with other techniques...

Most femoral artery arteriovenous fistulas occur as a result of percutaneous interventions. However, arteriovenous fistulas can occur in the setting of trauma, with resultant consequences such as heart failure, steal syndrome, or venous insufficiency. Indications for endovascular repair in this setting are limited to patients who are at too high risk for anesthesia, have a hostile groin, or would not survive significant bleeding. We report the case of a traumatic femoral arteriovenous fistula, causing severe venous insufficiency and arteriomegaly, in a 58-year-old male, with history of traumatic gunshot wound complicated by popliteal DVT...

BACKGROUND: Osteonecrosis of the femoral head (ONFH) often affects young active adults and leads to destruction of the hip joint and disabling arthritis. Several procedures have been developed to arrest the progress of osteonecrosis and postpone the procedure of total hip replacement especially in young patients. The aim of this multicenter study was to analyze the results of the use of the vascularized iliac bone flap transfer for management of ONFH. METHODS: From January 1985 to December 2012, a total of 2190 patients (2690 hips) with the mean age of 43...

Kimura's Disease (KD) is a rare chronic inflammatory disorder presenting as multiple painless solitary subcutaneous nodules, predominantly in the head and neck region and frequently associated with regional lymphadenopathy and/or salivary gland involvement. Because of painless nature and indolent course, there is usually a delay in the patient's presentation. KD may radiologically mimic other chronic inflammatory conditions like tuberculosis, vascular malformations and neoplasms. Clinical correlation and histological evaluation along with elevated peripheral eosinophil and serum IgE level are considered important for confirmatory diagnosis...

This report describes a novel approach of accessing the superficial veins of the upper extremity for the treatment of pulmonary emboli (PE) with an ultrasound enhanced thrombolytic infusion catheter. In a patient suffering from saddle PE and impending right heart failure, separate basilic and cephalic venous access sites in the right arm were utilized to insert EKOS EndoWave Infusion Catheter (EKOS Corporation, Bothell, WA) insertion in each pulmonary artery (PA). This technique could be advantageous, particularly for patients at high risk for access site complications and those unable to lie supine for prolonged duration of infusion therapy...

INTRODUCTION: Recent literature has reported an association between maternal supine sleep position and stillbirth during late pregnancy. In this position the gravid uterus almost completely obstructs the inferior vena cava. A small number of women experience supine hypotension, thought to be due in part to inadequate collateral venous circulation. The aim of this paper is to review the literature describing the anatomy of the collateral venous system and in particular the azygos system, the abdominal portion of which has not been well studied...

Interventional treatment of venous insufficiency has been revolutionized by endovascular techniques. Some of these techniques, and particularly thermal ablation (endovenous laser, radiofrequency) are now recommended as first-line therapy in the latest international guidelines. This is because of less post-operative pain, a shorter leave from employment and similar or lower recurrence rate. Endovenous techniques allow safer and more efficient treatment of certain particular conditions : small saphenous vein, ulcers, and recurrent varicose veins...

Cancer is frequently associated with a hypercoagulable state. Almost 15% of patients with cancer will suffer a thromboembolic event during their clinical course. The aetiology of this hypercoagulable state is multifactorial and includes procoagulant factors associated with malignancy as well as the host's inflammatory response. Cancer-associated thrombophilia can present as venous thromboembolism, migratory superficial thrombophlebitis, arterial thrombosis, disseminated intravascular coagulation, thrombotic microangiopathy and rarely non-bacterial thrombotic endocarditis (NBTE)...

Objective To obtain consensus on management criteria for symptomatic patients with chronic venous disease (CVD; C2-C6) and superficial venous reflux. Method We used a Delphi method by means of 36 statements sent by email to experts in the field of phlebology across the world over the course of three rounds. The statements addressed criteria for different venous treatments in patients with different characteristics (e.g. extensive comorbidities, morbid obesity and peripheral arterial disease). If at least 70% of the ratings for a specific statement were between 6 and 9 (agreement) or between 1 and 3 (disagreement), experts' consensus was reached...
