Secure intravenous IV access should be available with adequate extension tubing to allow drug and fluid administration at maximal distance from the image intensifier during fluoroscopy. These consist of a direct fistula between a spinal artery (usually artery of Adamkiewicz or ASA) draining into a dilated perimedullary venous plexus without an intervening nidus. The technology includes the use of balloons, catheters, microcatheters, stents, and therapeutic embolization (deliberately clogging up a blood vessel). Endovascular therapy is also applicable to vascular problems involving the spinal cord. The risk involved in endovascular treatment of this dural process is lower because spinal arteries are not involved directly.

Depuis plus d’un siècle, l'Hôpital Fondation Rothschild développe un savoir faire dans la prise en charge des pathologies de l’œil et du cerveau. Not only is the use of diagnostic angiography increasing, the role of intervention in neurologic injury has increased dramatically as well. With all of the fanfare associated with catheter-based angiography for diagnosing cerebrovascular abnormalities, it is worth noting that there is still a palpable complication rate somewhere between 0% and 1% that arises simply from diagnostic imaging defined as neurological deficit following the procedure [16,17]. Gross and Du (2013) performed a pooled analysis to demonstrate a 4% annual hemorrhage rate, increased to 10% with prior hemorrhage, similar to cerebral AVMs. Interventional Neuroradiology uses minimally invasive endovascular techniques combined with high-end imaging technology to treat cerebrovascular disease, including aneurysms, vascular malformations, ischemic stroke, and extracranial and intracranial atherosclerosis. Phase enhanced angiography is a powerful imaging modality, even more so when localized injections allow for a determination of localized blood flow. View Details; March … Following detailed diagnosis, interventional procedures to redirect neurovascular flow, reduce arterial pressure on aneurysms walls, or block defective and malformed blood transport pathways are considered. Interventional radiology is a medical specialisation that involves performing a range of imaging procedures to obtain images of the inside of the body. Type III lesions are also intramedullary lesions and are referred to as juvenile spinal AVMs. The technique has been evaluated in comparison to carotid endarterectomy within several clinical trials.132–134 This technique can be complicated by transient or permanent neurologic deficits secondary to emboli, dissection, or occlusion of the vessel. Stents are being used increasingly in the treatment of diseases of the supra-aortic vessels. Although advances in imaging capabilities, catheters, and embolic materials will advance endovascular capabilities, the knowledge, judgment, and experience of the angiographer will have the greatest effect in diminishing the risks of endovascular therapy. Phase contrast angiography is done on a nearly routine basis now and it is done on an outpatient basis. San Francisco was one of the first places to develop these procedures, and many of the leaders in the field trace their roots here. Pekka O. Talke, ... Christopher F.

Interventional Neuroradiology (INR) is a peer-reviewed clinical practice journal documenting the current state of interventional neuroradiology worldwide. Interventional neuroradiology (INR) procedures continue to increase in volume and complexity and are used to treat numerous different intracranial pathologies.1 The patients who require these procedures range from the neurologically intact outpatient population to the neurologically devastated critically ill population. The authors further argue that the particularly distinct and unique attribute within this type III category is the intradural and extradural extension of the lesion; thus they refer to the category as “juvenile extradural-intradural AVMs.”.

Importantly, these lesions can be associated with other AVMs in 15–20% of cases; thus a full angiographic evaluation of dural feeders throughout the central nervous system is warranted, including the cranial circulation, cervical cord, selective thoracic and lumbar intercostal injections, the iliac arteries, aorta, and the lateral sacral arteries (Larsen et al., 1995).
