BACKGROUND: Visible leg veins are not only a mere aesthetic problem, but may also be manifestation of altered microcirculation and superficial venous incompetency. Sclerotherapy is the first-line treatment for leg veins < 4 mm, but it often needs multiple sessions and sometimes fails. The main limitations of transcutaneous laser treatment are the diameter and the depth of the veins: the greater, the harder photothermolysis is, so that higher powers may lead to aesthetic complications...

BACKGROUND: Short (or small) saphenous vein (SSV) varices occur as a result of an incompetent sapheno-popliteal junction, where the SSV joins the popliteal vein, resulting in reflux in the SSV; they account for about 15% of varicose veins. Untreated varicose veins may sometimes lead to ulceration of the leg, which is difficult to manage. Traditionally, treatment was restricted to surgery or conservative management. Since the 1990s, however, a number of minimally invasive techniques have been developed; these do not normally require a general anaesthetic, are day-case procedures with a quicker return to normal activities and avoid the risk of wound infection which may occur following surgery...

INTRODUCTION: Adverse effects of sclerotherapy are rare. They are divided into two categories: immediate and delayed. Immediate adverse effects are mainly represented by visual disturbances. We are reporting the case of an immediate transient faintness following two sessions of foam sclerotherapy. OBSERVATION: An 80-year-old active female with superficial chronic venous disorder and no significant medical or surgical backgrounds experienced two similar immediate general adverse events following two sessions of sclerotherapy from a total of five...

BACKGROUND: Endovenous radio frequency ablation for small saphenous vein incompetence by and large appears to be superior and safer than conventional open surgery. Small saphenous vein ablation from approximately mid-calf to the point proximally where the small saphenous vein dives into the popliteal fossa is considered to be safe, as the sural nerve is in most cases separated from this segment of the small saphenous vein by the deep fascia. The outcome of the distal incompetent small saphenous vein remains unclear...

We report a case of pulsatile varicose veins successfully managed by endovenous laser treatment (EVLT) of the great saphenous vein (GSV). A 77-year-old woman taking an anticoagulant was transferred to our hospital for pulsatile varicose veins complicated with repeated venous bleeding from an ulcer of her left lower leg. Doppler echocardiography showed severe tricuspid regurgitation, and duplex ultrasonography revealed an arterial-like pulsating flow in the saphenofemoral junction and along the GSV, but an arteriovenous fistula, obstruction of the deep veins, and the distal incompetent perforators were not detected...

BACKGROUND: High altitude retinopathy (HAR) includes a number of diseases related to high altitude such as acute mountain sickness (AMS), high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE). High altitude retinopathy is mainly characterized by retinal hemorrhages, usually sparing the macular region, a condition specifically known as high altitude retinal hemorrhages (HARH). The pathogenesis of HARH is unclear. Many studies show that lack of oxygen causes an inadequate autoregulation of retinal circulation, causing vascular incompetence...

Cestmir Recek
Varicose vein disease is characterized by tenacious tendency to recur. Measures recommended to prevent recurrences (flush ligation at the saphenofemoral junction, removal of incompetent great saphenous vein in the thigh, and insertion of mechanical barriers in the fossa ovalis) did not succeed in preventing recurrence. Reflux recurrence is triggered by the hemodynamic phenomenon called hemodynamic paradox. Abolition of saphenous reflux removes the hemodynamic disturbance of any degree of severity but at the same time it releases the pathological process leading to recurrent reflux...

OBJECTIVE/BACKGROUND: Peripheral arterial occlusive disease (PAOD) is reported in about 15-20% of patients with venous leg ulcers (VLU). In such cases arterial recanalization is often recommended, and compression therapy is considered a contraindication when the ankle brachial pressure index (ABPI) is < 0.8. The aim of this study was to compare the outcome of patients with recalcitrant VLU, both without any arterial impairment ("pure venous recalcitrant leg ulcer" [pvRLU]) and with associated PAOD ("mixed arterial and venous recalcitrant leg ulcer" [mavRLU]), by treating only the venous disease...

INTRODUCTION: Ultrasound-guided foam sclerotherapy (UGFS) of varicose veins is a useful treatment option. It is a relatively safe method in the case of limited, small varicose veins. In theory, a justified concern could be raised that the injection of an active drug into the large superficial venous vessels may potentially cause life-threatening consequences. AIM: To assess the safety and efficacy of UGFS using a 2% solution of polidocanol (Aethoxysklerol 2%) in the case of great saphenous vein incompetence...

Chronic venous disease is defined as dysfunction of the venous system caused by incompetent venous valves with or without a proximal venous obstruction. Assessing the severity of the disease is challenging, since venous function is determined by various interacting hemodynamic factors. Mathematical models can relate these factors using physical laws and can thereby aid understanding of venous (patho-)physiology. To eventually use a mathematical model to support clinical decision making, first the model sensitivity needs to be determined...

BACKGROUND: Müllerian tract anomalies have been reported in 2-3% of females. Uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis (OHVIRA) syndrome is a rare condition, with only a few cases of the syndrome occurring during pregnancy having been reported. CASE: A 35-year-old, nulli-gravid woman at 18 weeks of gestation was referred due to cervical incompetence. Her first symptom was genital bleeding. Ultrasonography and MRI led to the diagnosis of OHVIRA syndrome, and pregnancy was confirmed on the affected side with the amniotic sac found to be protruding from the cervix into the vaginal cavity...

OBJECTIVE/BACKGROUND: To evaluate whether the outcome of radiofrequency ablation (RFA) treatment of great saphenous vein (GSV) incompetence may be predicted using strain-gauge plethysmography (SGP) with selective occlusion of the superficial venous system. METHODS: Seventeen patients (20 limbs) underwent endovenous RFA treatment for GSV incompetence (Clinical Etiology Anatomy Pathophysiology classification C2-C5; "C-group"). Duplex ultrasound (DUS) and SGP were performed with selective occlusion of superficial veins before and after RFA...

OBJECTIVE: Chronic venous ulcer (CVU) is a potentially debilitating condition that remains the most common etiology for leg ulcers. The condition has significant associated costs and effect on patient quality of life. That truncal reflux can be worsened by iliac vein occlusive disease is well known. However, there has not been systematic investigation of venous duplex ultrasound (VDUS) criteria to correlate common femoral vein (CFV) reflux with iliac vein stenosis. We sought to correlate VDUS criteria for predicting iliac vein stenosis and to investigate venous outflow factors associated with CVU recurrence...

PURPOSE: Cyanoacrylate closure of the great saphenous vein with the VenaSeal™ Closure System is a relatively new modality. Studies have been limited to moderate-sized great saphenous veins and some have mandated postoperative compression stockings. We report the results of a prospective study of cyanoacrylate closure for the treatment of great saphenous vein, small saphenous veins, and/or accessory saphenous veins up to 20 mm in diameter. METHODS: Fifty subjects with symptomatic great saphenous vein, small saphenous veins, and/or accessory saphenous veins incompetence were each treated at a single session...

OBJECTIVES: The objective is to identify the factors that affect the optimal linear endovenous energy density (LEED) to ablate incompetent truncal veins. METHODS: We performed a literature review of clinical studies, which reported truncal vein ablation rates and LEED. A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) flow diagram documents the search strategy. We analysed 13 clinical papers which fulfilled the criteria to be able to compare results of great saphenous vein occlusion as defined by venous duplex ultrasound, with the LEED used in the treatment...
