Prospective evaluation of endo venous laser therapy for varicose vein complications. The first report from Iran

摘要: Lower limb varicose veins are common, with a prevalence of %15 in men, and %25 women the United States (1). Many patients symptomatic, but their complaints may vary from subjective symptoms such as aching, leg heaviness, pruritus, muscle cramps, to more objective features edema, eczema, lipodermatosclerosis ulceration (2). Several treatment options available when there is no reflux, including sclerotherapy, hand-held lasers applied externally ambulatory phlebectomy for (3). The vast majority (60-80%) arise incompetence saphenofemoral junction (SFJ) great saphenous vein (GSV) reflux (4). When present, standard intervention SFJ ligation GSV stripping. Surgery usually requires general anesthesia, it associated significant perioperative morbidity, increased cost hospitalization delayed return normal activities work (5). Endovenous laser therapy (EVLT) new minimally invasive therapeutic option treating primary which provides an effective safe alternative conventional surgical management be done outpatient setting using local anesthesia (2, 6). wavelengths have been proposed, 810, 940, 980 respectively. At these wavelengths, power set between 10 15 Watts. energy administered endovenously, either pulsed fashion or continuously constant pullback fiber. all mentioned parameters, doses will range 20 J/cm 140 J/cm. These induce heating wall necessary cause collagen contraction destruction endothelium. Blood vaporization was found main vehicle damage (7, 8). Background: In recent years, endovenous has proposed treat incompetent greater increase patient comfort,and reduce well risk. EVLT causes thickening, luminal fibrosis. purpose this article, first report Iran, review our experience outline early results complication EVLT. Materials Methods: 22 (13 females 9 males, mean age: 40.6±11 range: 25-64) underwent segments 810-nm diode average 89.2 (range, 50-123 J/cm). Success rate defined absence throughout entire treated segment on follow-up doppler ultrasound (DUS) clinical resolution symptoms. Results: Short-term indicate 100% closure. Self-limiting were occurred 18% included moderate ecchymosis paresthesias 3 (13.5%), 1 (4.5%) patients, No major complications deep thrombosis pulmonary embolism occurred. DUS demonstrated 21 (95%) 19 (90.9%) occluded GSVs at 12 weeks, 24 weeks Conclusion: experiences excellent. 810 nm appears extremely technique. very best cosmetic rare side effects. Iran. J. Radiat.
