Background: Ovarian vein embolization was recently suggested as the preferred treatment for chronic pelvic pain syndrome.

Objective: To evaluate the technical feasibility, complications and early clinical and radiographic results of ovarian vein embolization in women with pelvic pain syndrome.

Methods: Percutaneous transcatheter ovarian vein embolization with coils was performed in six patients aged 27–53 years who presented with pelvic pain syndrome. All had lower abdominal pain, and pelvic varicosities were found on Doppler ultrasound and retrograde ovarian vein venography. Embolization was done unilaterally in three patients (on the left side) and bilaterally in three. Mean follow-up by telephone questionnaire was 7.3 months.

Results: The procedure was technically successful in all patients. Two patients reported partial relief of symptoms (33.3%) and three had complete relief (50%), for a total of 5 patients (83.3%) with some measure of improvement. There were no complications following the procedure.

Conclusions: Percutaneous transcatheter ovarian vein embolization seems to be safe and feasible for the treatment of pelvic pain syndrome. The procedure is performed on an outpatient basis and is well tolerated by patients.

Background: Radiofrequency ablation has recently become a viable treatment option for unresectable primary or secondary lesions confined to the liver.

Objective: To study the local therapeutic efficacy, side effects and complications of radiofrequency ablation for the treatment of hepatocellular carcinoma and liver metastases This is the first reported experience of radiofrequency ablation for treating malignant hepatic tumors in Israel.

Methods: Fifteen consecutive patients, aged 53–73 years, with 23 lesions (8 patients with HCC[1] and 7 with secondary liver tumors) underwent radiofrequency ablation under general anesthesia. RITA nine-array 5 cm thermal ablation catheter and the model 1500 generator were used. The mean diameter of all tumors was 4.28 cm (range 1–10 cm). Three lesions were 1–3 cm in diameter (small), 17 lesions measured 3.1–5 cm (medium), and 3 measured 5.1–10 cm (large).

Results: Complete necrosis was found in 8 (66%) of 12 HCCs by computed tomography scan. Of the remainder, diffuse tumor recurrence was demonstrated in three lesions (25%) after lipiodol injection and there was one local tumor recurrence. In the metastases group complete necrosis was found in 5 of 11 lesions (45%). One major complication (peritonitis) was treated with antibiotics and four (26%) minor complications (right pleural effusion, small subcapsular hematoma) were monitored.

Conclusions: Radiofrequency ablation appears to be an effective, safe and relatively simple procedure for the treatment of liver tumors.
