This study investigated whether microvenous reflux can be detected in limbs with chronic venous disease using superb microvascular imaging (SMI) and colour Doppler imaging. Participants with venous disease (limbs, n = 26) and without venous disease (limbs, n = 10) were studied. The skin in the medial gaiter region was imaged using both SMI and colour Doppler to identify reflux in the small vessels in response to distal augmentation. The diameters and depths of responsive vessels were measured. In limbs with venous disease, reflux in response to provocation was visualised with SMI in a greater number of vessels (12/26 versus 4/26) and smaller vessels than with colour Doppler...

BACKGROUND: Long segment occlusive disease in the superficial femoral artery remains a treatment challenge despite advances in open surgical and endovascular approaches. We report initial clinical results of an entirely new procedure to perform femoropopliteal bypass using the DETOUR System to create a stentgraft bypass which originates in the SFA, travels through the femoral vein, and ends in the popliteal artery, bypassing the diseased segment. METHODS: Review the initial results of the first five patients at a single site enrolled in IRB-approved, prospective clinical study using the DETOUR System...

INTRODUCTION: Patients with plaster cast immobilization of the lower limb have an estimated symptomatic venous thromboembolism rate of 5.5%. However, there is currently no practical physical prophylaxis for deep-vein thrombosis (DVT). The objective of this study was to examine the effects of forced deep breathing on peak blood velocity in the superficial femoral vein (PBVFV), which is a surrogate measure of the efficacy of thromboprophylaxis against DVT, in patients with plaster cast immobilization of the lower limb...

Congenital fibrinogen disorders are caused by mutations in one of the three fibrinogen genes that affect the synthesis, assembly, intracellular processing, stability or secretion of fibrinogen. Functional studies of mutant Bβ-chains revealed the importance of individual residues as well as three-dimensional structures for fibrinogen assembly and secretion. This study describes two novel homozygous fibrinogen Bβ chain mutations in two Slovak families with afibrinogenemia and hypofibrinogenemia. Peripheral blood samples were collected from all subjects with the aim of identifying the causative mutation...

BACKGROUND: In a deep epigastric artery perforator (DIEP) flap breast reconstruction, the necessity of additional anastomosis of the superficial inferior epigastric vein (SIEV) should be determined intraoperatively. The purpose of this pilot study is to propose a method to detect venous congestion intraoperatively using the blood glucose measurement index (BGMI). METHODS: In 70 DIEP flaps of 67 patients for breast reconstruction, the ratio of blood glucose content in the flap to systemic blood glucose (BGMI) was measured immediately after wound closure...

BACKGROUND: Smoking has been associated with wound healing complications and overall morbidity in multiple specialties, including plastic surgery. From 2005 to 2014, smoking prevalence among U.S. adults decreased from 20.9 percent to 16.8 percent. This study aims to investigate whether smoking prevalence among plastic surgery patients paralleled the national trend and whether smoking was an independent risk factor for postoperative complications. METHODS: The 2005 to 2014 American College of Surgeons National Surgical Quality Improvement Program database was used to examine smoking prevalence and 30-day postoperative complications in 36,454 patients who underwent common plastic surgical procedures with extensive planes of dissection...

Due to gravity the venous vasculature in the lower extremities is exposed to elevated pressure levels which may be amplified by obesity or pregnancy. As a consequence, venules dilate and may be slowly transformed into varicose or spider veins. In fact, chronically elevated venous pressure was sufficient to cause the corkscrew-like enlargement of superficial veins in mice. We hypothesized that biomechanical activation of endothelial cells contributes to this process and investigated the inhibitory capacity of Magnolol in this context - a natural compound that features multiple properties counteracting cellular stress...

OBJECTIVE: Endovenous thermal ablation has become the primary modality of treatment for patients with venous insufficiency. Previous literature has provided reviews of radiofrequency ablation (RFA) or endovenous laser ablation (EVLA) that mostly focus on the great saphenous vein (GSV) and small saphenous vein (SSV). Data with an extended review including the anterior accessory saphenous vein (ASV) and perforator veins (PVs) have been limited. This study examines the treatment of venous insufficiency with RFA and EVLA of these multiple veins to identify clinical and demographic predictors of both the early success and thrombotic complications of endovenous thermal ablation...

Modern invasive treatment of superficial venous insufficiency of the lower extremities is largely based on the use of intravenous procedures under ultrasound guidance. The first-line treatment is thermoablation, in which the insufficient superficial vein, typically vena saphena magna or parva, is constricted by using laser or radio frequency energy under ultrasound guidance. The procedure is nearly always successful under local anesthesia and can be performed as an outpatient operation. When necessary, visible collateral varices can be treated with foam sclerotherapy or by surgical excision...

Venous insufficiency of the lower limb is a common disease. Diagnosis is based on symptoms, clinical findings and duplex ultrasound. Consideration and planning of invasive treatment cannot be performed without ultrasound. Vast majority of invasive treatments in superficial venous insufficiency can be done by ultrasound-guided endovenous methods with local anesthesia. Thermoablation (laser of radiofrequency) is the first-line treatment. There are promisisng endovenous methods for treatment of deep venous obstruction in selected cases...

Acute thrombosis of the lower limb deep veins remains one of the most common vascular diseases. It is characterised by formation of thrombotic masses in the system of the deep veins of the lower extremities. A serious complication associated with deep vein thrombosis is pulmonary embolism. In rare cases, under certain conditions a massive and disseminated blockade of the venous outflow with thrombotic masses may lead to ischaemia of the extremity with the formation of superficial and deep necroses and later on to gangrene...

BACKGROUND: Arteriovenous fistula (AVF) is defined as an abnormal communication between the high flow arterial system and the low flow venous network, which directly connects the arterial feeding vessels and the near draining veins without normal intervening capillary bed. Arteriovenous fistula incurs in preauricular region is exceeding rare. Most of these fistulae occur as a result of an iatrogenic injury, the volume is small, feeding and draining vessels of feeding and draining are simple, and can be cured easily...

Jan Beyer-Westendorf
The management of superficial vein thrombosis (SVT) is poorly defined and remains controversial overall. SVT has long been considered a benign, self-limited disease, but recent studies show that SVT carries a nonnegligible risk for recurrence, deep vein thrombosis, or pulmonary embolism. Current guidelines recommend the use of low-molecular-weight heparin or fondaparinux, but results of several surveys indicate that the majority of patients with SVT receive nonanticoagulant therapy only, which includes compression stockings or bandages, nonsteroidal anti-inflammatory drugs, topical application of heparin gel, or surgical interventions...

INTRODUCTION: Venous malformations (VMs) are ubiquitous, low-flow vascular anomalies known to be occasionally painful due to thrombotic episodes within the lesion. The prevalence of superficial or deep vein thrombosis is unclear. METHODS: A cross-sectional study among outpatients aged ≥ 12 years with pure VMs was performed, quantifying the prevalence of thrombosis by screening all patients with compression ultrasonography (CUS). Additionally, we evaluated whether coagulation alterations were related to thrombosis observed with CUS...

Idiopathic normal pressure hydrocephalus (iNPH) is a highly prevalent condition in the elderly population; however, the underlying pathophysiology in relation to the aging process remains unclear. To investigate the effect of removal of cerebrospinal fluid by lumbar "tap test" on the cerebral circulation in patients with iNPH, 14 patients with "probable" iNPH were studied using a novel blood tracking technique based on blood oxygenation level-dependent (BOLD) magnetic resonance signal intensity. By tracking the propagation of the low-frequency component of the BOLD signal, extended venous drainage times were observed in the periventricular region of the patients, which was reversed by tap test...

Long-term iliofemoral complications induced by radiation include vascular (arterial and venous) lesions, nervous lesions and soft tissue loss that can be cutaneous and subcutaneous and potentially lead to radionecrosis with vessel exposure. We present five cases of groin radionecrosis. There were three men and two women (age 30-73 years). Radiotherapy had been delivered 15 years earlier in three cases, and 2 years earlier in two cases. Symptoms were intermittent claudication (n=1), critical ischemia (n=1), and septic hemorrhage (n=1)...
