Endovenous laser treatment (EVLT) for the saphenous reflux and varicose veins: a follow-up study.

PURPOSE: The aim of this study is to report our experience about endovenous laser treatment (EVLT) for lower extremity varices in our centre which was followed by ultrasonography during the 6-month period. METHODS: During a 1-year period, 46 patients who were treated by EVLT with the 940-nm diode laser for venous insufficiency enrolled in the study. The diagnosis of greater saphenous vein (GSV) incompetence with reflux was made by clinical evaluation and duplex Doppler examinations. Clinical outcomes, complications and duplex ultrasound of the GSV were assessed within 1 week, 1 month, 3 months and 6 months, after the endovascular laser treatment. RESULTS: The mean age of our patients was 44 ± 11 years (24-70), and among them, 23 (50%) were male. Improvement in visible varicosity was seen in 39 (84.8%) patients after 6 months (P value = 0.011). The baseline mean diameter of GSV was 4.9 ± 1.6 mm and it dropped to 3.5 ± 1.3 after 6 months (P < 0.0001). After 6 months, 95.7% of our patients were satisfied and recommended this procedure to others. CONCLUSIONS: Endovascular laser ablation seems to be a safe and effective method for the treatment of lower limb varices.

Transcatheter embolization of congenital hepatic arteriovenous malformation using ethylene-vinyl alcohol copolymer (Onyx).

A male infant with high-output heart failure who had been found to have a hepatic arteriovenous malformation by ultrasound imaging was referred to our center (Department of Diagnostic and Interventional Radiology, Imam Khomeini Hospital, Tehran University of Medical Sciences, Islamic Republic of Iran) for further evaluation. Computed tomography angiography revealed a large hepatic arteriovenous malformation with feeders originating from enlarged hepatic arteries and draining to enlarged hepatic veins. We performed a transcatheter embolization of the anomaly using ethylene vinyl alcohol copolymer (Onyx) during a single session. The cardiac function of the infant rapidly improved after the procedure. Over the 19 months of follow-up, his cardiac output remained stable and within the normal limits, and no complications were detected.
