Abstract

Hyperdynamic arteriovenous malformations are a relevant therapeutic problem because of the complexity and variability of their presentation. The incidence of this angiodysplasia is quite low, so that only few institutions have treated more than a few patients, which certainly does not help treatment optimization. The role that transcatheter embolization has gained during the last years has fostered growing interest in this method, even though surgery remains the treatment of choice. Transcatheter embolization is a highly effective treatment, which can ensure long-lasting, although rarely definitive, hemodynamic results. The authors report their experience in 39 patients affected with hyperdynamic arteriovenous malformations. The total number of percutaneous embolization sessions was 81. In 11 patients a preoperative treatment was performed 48 hours before surgery. In all cases polyvinyl alcohol particles were used, whose diameter ranged 250-500 micron. The results, with a mean follow-up of 53 months, are reported. In the 11 patients who underwent combined surgery plus embolization treatment, conservative surgical resection was radical in 73% of cases. As for the other patients, the result was substantial in 46% of cases, partial in 27% and modest or insignificant in 27% of cases. The total incidence of major complications was 6.2%. Our experience confirms that transcatheter embolotherapy, although yielding effective long-term results, has a mostly palliative role.
