A calcified nodule is a type of potentially vulnerable plaque accounting for approximately 2% to 7% of coronary events. Because its intravascular ultrasound (IVUS) features have never been validated, the aim of this study was to assess the IVUS characteristics of calcified nodules in comparison to histopathology. IVUS was performed ...

All three coronary arteries originating from a single coronary ostium is a rarity. Single coronary artery (CA) arising from the left aortic sinus is far more uncommon than one arising from the right sinus. Usually in such cases, the right coronary artery (RCA) arises as a distal continuation of the ...

Imbalance of matrix metalloproteinase enzymes (MMP) and their inhibitors (TIMPs) may contribute to the development of varicose veins. We hypothesised that, histological changes in varicose vein wall correlate with alterations in expression of MMP/TIMP. Varicose veins (n=26) were compared with great saphenous vein (GSV) segments (n=11) from arterial bypass, and ...

Physicians have several options to treat varicose veins that remain after successful axial vein ablation. Foam sclerotherapy is effective for all sorts of veins, but may become less effective and have a higher risk of complications when treating large diameter veins. Endovenous laser and radiofrequency ablation can be used to ...

BACKGROUND: Disordered programmed cell death may play a role in the development of venous diseases. Tissue hypoxia caused by blood stagnation and venous hypertension is the similar etiology of varicocele and varicose veins. We studied the vascular histopathology and determined whether there is the same apoptotic pathway in both venous ...
Lim C S - - 2009
BACKGROUND: Valvular incompetence and reflux are common features of primary varicose veins, and have long been thought to be their cause. Recent evidence, however, suggests that changes in the vein wall may precede valvular dysfunction. METHODS: A literature search was performed using PubMed and Ovid using the keywords 'varicose vein ...

Varicose veins are common and increasingly are being treated by less invasive endoscopic methods such as foam sclerotherapy. Patent foramen ovale (PFO) is also common, present in approximately one-quarter of adults. PFO allows bubbles introduced by foam sclerotherapy to cross into the general circulation, potentially causing cerebral artery gas embolization ...

BACKGROUND: Reoperations for bypass surgery increase the need for new grafts. We investigated early changes in both the normal human saphenous vein and in ectatic varicose veins externally supported by PTFE (polytetrafluoroethylene) graft and exposed to arterial pressure in an IN VITRO non-pulsatile flow model. MATERIAL AND METHODS: A total ...

Endovenous laser ablation (EVLA) obliterates incompetent truncal veins as an alternative to varicose veins surgery. We describe 3 patients who developed an arterio-venous fistula (AVF) following great (GSV: 1) or small (SSV: 2) saphenous vein EVLA. Two fistulae closed spontaneously with conservative management. Concomitant venous and arterial wall thermal injury ...

Previous animal models of venous disease, while inducing venous hypertension and valvular insufficiency, do not produce superficial varicose veins. In this study, we aimed to develop and characterize a pig-based model of superficial varicose veins. Right femoral arteriovenous fistulae (AVF) were surgically fashioned in young adult pigs. Animals were examined ...

The author's preferred treatment for spider veins is sclerotherapy, a technique that uses irritants to obliterate the vessel lumen. She reserves laser treatment for vessels too small to sclerose, matting, and patients who refuse sclerotherapy. Treatment is initiated only after ruling out reflux in the larger superficial venous systems or ...

Matrix metalloproteinases (MMPs) play a major role in extracellular matrix (ECM) turnover under both physiological and pathological conditions. Studies on venous tissues from experimental animals and humans identified several MMP subtypes, and showed significant changes in the expression and activity of specific MMPs during vein wall remodeling. Also, significant research ...

BACKGROUND: Although endovenous laser ablation has been demonstrated to effectively occlude incompetent saphenous veins, it does not treat branch varicosities directly. OBJECTIVE: The objective was to evaluate the technical feasibility and early results of the direct ablation of branch varicosities using a 980-nm diode laser. MATERIALS AND METHODS: From July ...
Lane R J - - 2007
OBJECTIVES: The incidence of recurrent varicose veins remains high despite the development of new ablative treatments for varicose veins associated with incompetence of the saphenofemoral junction. External valvular stenting (EVS) of the terminal and/or subterminal valves of the great saphenous vein (GSV) provides a reparative, physiological approach that requires long-term ...

Treatment of venous insufficiency with liquid sclerotherapy is considered by some to be an unfulfilled promise. It was heralded in the first half of the last century to be a replacement for surgery, but as recurrences of varicose veins appeared in limbs treated with injection techniques, surgery reappeared and was ...
Naoum Joseph J - - 2007
Varicose veins (VVs) classically result from venous hypertension owing to incompetence of the major communications between the superficial and deep veins of the lower extremity. In a significant number of patients, there is no demonstrable truncal saphenous reflux and varicosities are the result of isolated perforating and nonsaphenous vein incompetence. ...

Varicose vein disease is a frequently occurring pathology with multifactorial causes and a genetic component. An intense remodelling of the varicose vein wall has been described and could be at the origin of its weakness and altered elasticity. We have described previously a dysregulation of collagen synthesis in cultured smooth ...
