SARAJEVO, (epssa-pr) In the period from April 18 to 21, 2012, a series of neuroradiological procedures were performed at the Radiology Clinic of the Clinical Center of the University of Sarajevo (KCUS). For the first time in Bosnia and Herzegovina, an AVM (arteriovenous malformation) in the brain was treated with Onix. The patients were treated by Prof. Dr. Daniel Hoit neurosurgeon (Memphis, Tennessee, USA) together with the team of interventional neuroradiologists (Prim. Dr. Zulejha Merhemić, Dr. Edin Avdagić, and Dr. Denis Bulja). Professor Hoyt was brought to KCUS by his colleague Prof. . Ph.D. Kenan Arnautović to perform more modern neuroradiological treatments on patients waiting for these procedures within the framework of the 4th Day of BHAAAS in BiH (Bosnian-Herzegovinian-American Academy of Sciences and Arts) with colleagues from the KCUS Radiology Clinic. In one patient, coiling of the aneurysm on the internal carotid artery was performed, and in one patient, a stent was placed in the carotid artery, thus widening the marked narrowing. An AVM (arteriovenous malformation) in the brain was treated with Onix. One part of the AVM was occluded, and the size of the arteriovenous malformation was reduced to the size that can be treated with radiosurgery (Gamma-knife). Modern treatment of arteriovenous malformations consists of surgery, stereotaxic radiosurgery (gamma knife), and embolization, methods that are most often combined. Embolization is performed to reduce the size of the AVM and thus enable the surgical procedure to be safe or to enable treatment with radiosurgery. Previously, an n-BCA occlusion agent was used, which hardened very quickly, so the catheter through which it is applied might remain in the patient. A much less aggressive agent for embolization is Onix, which hardens more slowly and thus occludes the arteries that supply blood and the nidus of arteriovenous malformations, reports KCUS.
