Introduction. Despite the contemporary diagnostics of intracranial aneurysms their treatment is still a great challenge. The decision when and if to apply a surgical or endovascular treatment of intracranial aneurysms should be made by a team of medical specialists which consists of a cerebrovascular neurosurgeon, neuro-radiologist and neuro-anesthesiologist. Case Report. We report a case of a patient aged 16 who was admitted because of a sudden intensive headache followed by sickness, vomiting, and loss of consciousness. On admission the patient was conscious but sleepy. Glasgow Coma Scale score was 14 and the World Federation of Neurological Surgeons Scale grade was I. The computed tomography scan showed a massive subarachnoid haemorrhage. The computed tomography angiography and digital subtraction angiography revealed a ruptured saccular aneurysm in the left vertebral artery. An early treatment with the coiling of the lumen of the aneurysm was performed under general anaesthesia. On the tenth day the boy was discharged in good condition and without any neurological deficits. Six months after the intervention the patient was without symptoms and the control digital subtraction angiography showed the complete occlusion of the aneurysm. Conclusion. Intracranial aneurysms in children are more common in males and are predominantly localized in the posterior circulation. In addition, they are frequently of greater size and more complex architecture and they are associated with a lower incidence of clinically manifest vasospasm. According to previous experience, endovascular treatment of intracranial aneurysms in paediatric patients has proven to be a safe and efficient method with a small number of complications.

✓ Intraoperative digital subtraction angiography using commercially available equipment was employed to confirm the precision of the surgical result in 105 procedures for intracranial aneurysms or arteriovenous malformations (AVM's). Transfemoral selective arterial catheterization was performed in most of these cases. A radiolucent operating table was used in all cases, and a radiolucent head-holder in most. In five of the 57 aneurysm procedures, clip repositioning was required after intraoperative angiography demonstrated an inadequate result. In five of the 48 AVM procedures, intraoperative angiography demonstrated residual AVM nidus which was then located and resected. In two cases intraoperative angiography failed to identify residual filling of an aneurysm which was seen later on postoperative angiography, and in one case the intraoperative study failed to demonstrate a tiny residual fragment of AVM which was seen on conventional postoperative angiography. Two complications resulted from intraoperative angiography: one patient developed aphasia from cerebral embolization and one patient developed leg ischemia from femoral artery thrombosis. This technique appears to be of particular value in the treatment of complex intracranial aneurysms and vascular malformations.

Abstract OBJECTIVE Reliable and rapid delineation of arteriovenous malformations enables the application of effective treatments such as stereotactic radiosurgery. We describe a new method to improve the speed and reliability of visualizing the flow of contrast images with digital subtraction angiography. METHODS In line with current practices, digital subtraction angiography was used to produce a sequence of grayscale images. The new method combines the standard grayscale images produced by digital subtraction angiography into a single composite color image that encodes the contrast arrival time at each point of the brain's circulatory system. The algorithm is simple, fast, and easy to implement. RESULTS The technique allows the flow of contrast from a series of angiography images to be summarized in a single color image. CONCLUSION This visualization method promises to improve the speed of manual delineation of arteriovenous malformations. Further studies are required to evaluate the clinical value of the use of color intensity projection images, supplemented by grayscale images as necessary, in comparison with contouring on grayscale images only.
