BACKGROUND Minimally invasive techniques to treat great saphenous varicose veins include ultrasound-guided foam sclerotherapy (USGFS), radiofrequency ablation (RFA) and endovenous laser therapy (EVLT). Compared with conventional surgery (high ligation and stripping (HL/S)), proposed benefits include fewer complications, quicker return to work, improved quality of life (QoL) scores, reduced need...

V ar ic os e V ei ns Endovenous interventions have transformed the treatment of varicose veins during the past decade. Interest in minimally invasive endovenous thermal ablation of the saphenous vein has substantially increased due to multiple reasons. Both radiofrequency ablation (RFA) and endovenous laser therapy (EVLT) can be performed as an office procedure; they are less invasive and usual...

PURPOSE To assess the efficacy of endovenous laser therapy (EVLT) in the treatment of lower-limb venous ulcers secondary to venous reflux. MATERIALS AND METHODS Forty-four of 139 patients referred for EVLT from January 2004 to August 2007 had nonhealing venous ulcers. Preprocedural duplex ultrasound (US) was performed to document saphenous venous reflux secondary to saphenofemoral/saphenopopl...

Managing and equitably attributing workload in the vascular laboratory is challenging because of wide variety examinations that sonographers perform. We developed an effort-based method measuring sonographer laboratory. Vascular (n = 11) at academic medical center anonymously rated overall effort required to perform 39 different for which standard protocols existed. The a unilateral lower extre...

لیزر درمانی درون وریدی(evlt) یک روش گرما درمانی به صورت حداقل تهاجمی برای درمان وریدهای واریسی است. مدل کردن اثر لیزر بر بافت در evlt مزیت های زیادی دارد. در این تحقیق، evlt به صورت سه بعدی شبیه سازی شده است. برای انتشار نور در بافت از روش های تقریب دیفیوژن و مونت کارلو با گام متغیر و جذب تدریجی استفاده شده است. معادله گرمایی پنس و معادله آرنیوس به ترتیب برای مدل کردن انتقال گرما و ایجاد آسیب د...
