Endovenous treatment of incompetent anterior accessory saphenous veins with a 1540 nm diode laser.

AIM: Endovenous laser treatment (EVLT) is an accepted form of axial vein ablation for symptomatic venous reflux but its role in the treatment of anterior accessory saphenous vein (AASV) has not been well characterized. The aim of this paper is to show the short-term result of EVLT with a ball-tipped fiber and a 1540 nm diode laser of the AASV with preservation of a competent great saphenous vein (GSV). METHODS: Nine incompetent AASV veins in 8 patients (6 female) were treated. The gravity of chronic venous disease was determined according to the CEAP classification and the severity of symptoms was scored according to the revised Venous Clinical Severity Score. Patient satisfaction was assessed by a 0 to 3 scale. RESULTS: The average linear endovenous energy density was 60.5 J/cm vein (SD: 7.5). Patients returned to daily activities after a mean of 3.8 days (SD: 1.4). 5 patients (63%) have had pain but of mild intensity. No patients developed paresthesia or phlebitis reactions in the treated area. Post-operative ecchymoses are frequent (89%). During the follow-up period (mean 13 months, range: 7-17 months) all the veins were occluded. The VCSS improved drastically from a mean of 3.2 (SD: 1.3) preinterventional to 0 (SD: 0.38) at 17 months. All patients were satisfied or very satisfied with the method. No severe complications occurred. CONCLUSION: EVLT of an incompetent AASV with a 1540 nm diode laser is a safe and efficient therapy option, with a high success rate and with no evidence of GSV neo-reflux or recurrent varicosities during the follow-up period.

Endovenous thermal ablation. Standardization of laser energy: literature review and personal experience.

Endovenous laser treatment is a new, minimally invasive technique for ablation of the incompetent great and small saphenous vein and their tributaries. Although the satisfactory safety/efficacy results of this technique, literature is poor regarding standardization of the energy needed to ablate the incompetent vein in order to have success and durability of the procedure. The aim of this paper is a review of the literature to find out if authors with large experience on endovenous laser treatment achieved a standardization of the delivered energy at the incompetent vein wall and if new concepts proposed by the authors, like cold saline anesthesia, echogenic vein occlusion and regular distribution of laser energy to the vein wall, can improve the technique in order to have optimum results.

[Approach to juxtarenal inflammatory aneurysms]. / L'approccio agli aneurismi infiammatori iuxtarenali.

The incidence of inflammatory abdominal aortic aneurysm (IAAA) in a late review of the literature is estimated about 2-15% overall aortic aneurysms. In our data this type of aneurysm is 3.6 overall aortic aneurysms treated. In the majority of the cases, IAAA is juxtarenal or infrarenal. Ethiopathogenesis of IAAA till today is not certain. Recent hypothesis on IAAA attribute the same ethiopathogenesis in both atherosclerotic and inflammatory aneurysm. The interaction of genetic, environmental and infective factors should be able to determine an autoimmune inflammatory reaction of variable severity. 80% of the patients suffering from IAAA present abdominal or lumbar pain, loss of weight and increase of the RC sedimentation velocity. The IAAA's natural history goes to rupture. Entrapment of nearstanding organs totally involved in the fibrotic process is the most frequent complication. Usually there is a compression of the ureter and the duodenum with consequenced hydroureteronephrosis and bowel obstruction. Preoperative diagnosis is possible; CT scan and MRI guarantee and accuracy about 90%. Intraoperatively the external wall of IAAA appears whitish and translucent and always there are tenacious adhesion given by the avventital wounds inflammation. Confirm is given by the histological examination of the aneurysmatic wall and peravventitial tissues. Our experience and a late review of the literature concorde that surgical indication for the treatment of IAAA is the same for the atherosclerotic one. This conviction is supported by the fact that the diagnostic methodical evolution and the improvement in mininvasive surgical technique lowered perioperating morbility and mortaliy. We prefer, according with many authors, retroperitoneal approach to juxtarenal IAAA, instead of standardized transperitoneal access with xifo-pubical or transversal under costal incision. This approach offers some advantages as easier exposition of aorta, whose postero-lateral wall is hardly ever involved in inflammatory process, little duodenum's and left renal veins manipulation and low incidence of paralytic ileum and respiratory disease. Endovascular surgery hasn't in this moment any role in juxtarenal IAAA treatment because this type of aneurysm has inadequate proximal neck. In the future, probably, endovascular repair will be possible using a new type of endograft with renal legs. Often surgical treatment is inadequate to control retroperitorenal fibrosis and so surgeon has to use perioperating pharmacolocical therapy.
