This report discusses the observation of multiple retinal emboli following placement of a new carotid stenting device. Especially dense plaques in the carotid artery can shatter into dust-like particles that may be fine enough to penetrate the filter of the new device, thus posing the danger of retinal perfusion.

Successful varicose vein surgery depends on accurate preoperative assessment and individualized treatment for various combinations of venous insufficiency. Noninvasive duplex scanning is currently the gold standard in varicose vein evaluation. Flush ligation and division of the great saphenous vein and its tributaries, inverted downward stripping to below the knee combined ...

Mondor's disease of the penis, otherwise known as superficial thrombophlebitis (STP) or thrombosis of the dorsal vein, is an under-reported benign condition, the aetiology of which is poorly understood. It is characterized by a sudden, indurated swelling of the vein, often occurring after vigorous sexual activity. We report a case ...

Varicose veins have been linked to great saphenous vein (GSV) reflux and in particular, with reflux at the saphenofemoral junction (SFJ). Early stages of disease, however, may be associated with limited, localized reflux in segments of the GSV and/or small saphenous vein (SSV). Ultrasound mapping of saphenous veins was performed ...

Venous insufficiency in its severe forms leads to skin changes which, in turn may be treated by surgical therapy. Interventions are directed towards correction of the underlying abnormal venous physiology. This involves removal of varicose veins and ablation of incompetent axial veins and relevant perforating veins. In performing ablation of ...

Varicose veins are characterized by dilated and thickened vein walls. This study examined whether the changes that occur in varicose veins are associated with smooth muscle cell (SMC) hypertrophy, cellular proliferation or apoptosis. Moreover, the association between SMC hypertrophy and the expression of the estrogen receptor-beta (ERbeta) was investigated. Varicose ...
El Wajeh Y - - 2004
BACKGROUND: Recurrence of varicose veins after apparently adequate surgery is common. Neovascularisation, the formation of new vascular channels between a venous surgery site and new varicosities, is thought to be an important cause of recurrence. The aim of this study was to provide histological evidence of the 'neovascularisation'process. METHOD: Tissue ...

The first natural occurrence of ringwoodite lamellae was found in the olivine grains inside and in areas adjacent to the shock veins of a chondritic meteorite, and these lamellae show distinct growth mechanism. Inside the veins where pressure and temperature were higher than elsewhere, ringwoodite lamellae formed parallel to the ...

BACKGROUND: One of the shortcomings of the CEAP classification is that some of the clinical conditions in the original version were not defined and, therefore, were used in different ways by those who work with CEAP. AIM: To clarify the definitions of the seven clinical classes in the CEAP classification ...

The recurrence of varicose veins is a common and costly consequence of varicose vein surgery. Despite the long history and vast experience of varicose vein surgery, the exact cause of recurrence is still unknown. This study aims to investigate the cause of recurrence further by correlating findings from duplex ultrasound ...

The expression of cytochrome P450 (CYP) enzymes and cyclo-oxygenases (COX) was investigated in human saphenous veins by reverse transcription-polymerase chain reaction analysis. Non-varicose veins were obtained from patients undergoing aortocoronary bypass grafting, whereas varicose veins were obtained from patients undergoing stripping removal of varicose saphenous veins. In non-varicose veins, CYP1B1, ...

Saphenous veins were taken for examination: unchanged, varicose with thrombophlebitis and varicose thrombus. The contents of haemoglobin and protein were determined in the homogenate of that material. Only small quantities of haemoglobin were found in walls of unchanged veins. Greater amounts of haemoglobin were observed in walls of varicose veins, ...

Superficial vein thrombosis (SVT) risk factors are close to those of venous thromboembolism (VTE). Diagnosis is made in a clinical setting but ultrasonography is useful to eliminate concomitant deep vein thrombosis (DVT). For SVT of the lower limbs, which is the main location, varicose veins represent the principal cause but ...

Ambulatory phlebectomy has proven to be an effective treatment for varicose veins. Alone or complementing the treatment of incompetent long or short saphenous vein by high ligation, saphenectomy, or transcatheter occlusion, ambulatory phlebectomy not only adequately and satisfactorily removes the diseased veins but also results in a series of extremely ...

Telangiectasias and/or varicose veins are present in about 33% of adult women and 15% of adult men. Although they may be only of cosmetic concern, superficial varices often cause significant symptoms such as pain, aching, heaviness, and pruritus. Venous ulceration is commonly caused solely by superficial venous insufficiency. Superficial thin-walled ...

A patient with Sotos syndrome presented with a history of massive bleeding from varicose veins of the right leg, requiring hospitalization. Investigations revealed that his bilateral varicose veins and the associated leg edema were secondary to the inferior vena cava getting compressed by an asymptomatic grossly hydronephrotic right kidney. The ...

Conservative hemodynamic surgery for varicose veins is a minimally invasive, nonablative technique that preserves the saphenous vein and helps avoid excision of varicosities. It represents a physiologic approach to the surgical treatment of varicose veins based on knowledge of the underlying venous pathophysiology gained through detailed duplex scanning. A change ...
Corrales N E - - 2002
BACKGROUND: The incidence of long saphenous vein (LSV) duplication has not been clearly established. This anomaly could have implications for recurrence after varicose vein surgery. METHODS: Some 103 saphenograms obtained in 85 patients being considered for peripheral arterial bypass surgery were reviewed. Non-ionic contrast medium was injected directly into the ...

The aim of this study was to demonstrate that sclerotherapy of exceptionally large varicose veins, i.e., >2.0 cm in diameter, is achievable, and should be the method of choice if one wishes to preserve the greater saphenous vein as a source for future bypass grafts. There is an increasing propensity ...

Patients with tissue perfusion deficit usually have lactic acidosis or hyperlactacidemia and blood lactate level has been used to diagnose this condition and to monitor the disease progression. We conducted a study to examine the diagnostic accuracy of capillary and arterial lactate (C LAC and strip A LAC) obtained by ...

Primary varicose veins are functionally characterized by venous back-flow and blood stagnation in the upright position. Dilatation and tortuosity provide evidence for progressive venous wall remodelling, with disturbance of smooth muscle cell/extracellular matrix organization. Affected areas are not uniformly distributed, some areas being hypertrophic, whereas others are atrophic or unaffected. ...
Kirsch D - - 2000
Conflicting theories on the development of primary varicosis have led to the molecular biological investigation of the vein wall or, more accurately, of the extracellular matrix. It was the aim of this study to quantify matrix expression and to compare pathological changes in the vein wall with valve-orientated staging of ...
