Importance of interventional neuroradiology curriculum in neurology standardizedresidency training / 中华医学教育探索杂志

After more than3 years of pilot (since 2010), standardized training of resident physicians in Shanghai has made great progress, however, it still needs to be improved. Cerebral and spinal vascular diseases are main types of neurological diseases and they seriously influence people's life and health. Interventional neuroradiology plays an important role in the diagnosis and treatment of cerebral and spinal vascular diseases. However, in the current residency training system in Shanghai or other provinces of China, the training of interventional neuroradiology is not included. In this paper, the authors analyzed the important role of interventional neuroradiology in diagnosis and treatment of cerebral and spinal vascular disorders and discussed the feasibility, method, and time arrangement of including interventional neuroradiology curriculum into the schedule of neurology standardizedresidency training and hoped to provide reference for the relevant departments to formulate a future policy.

Anesthetic Consideration for Neurointerventional Procedures / 신경중재치료의학

Interventional neuroradiology (INR) has been a rapidly expanding and advancing clinical area during the past few decades. As the complexity and diversity of INR procedures increases, the demand for anesthesia also increases. Anesthesia for interventional neuroradiology is a challenge for the anesthesiologist due to the unfamiliar working environment which the anesthesiologist must consider, as well as the unique neuro-interventional components. This review provides an overview of the anesthetic options and specific consideration of the anesthesia requirements for each procedure. We also introduce the anesthetic management for interventional neuroradiology performed in our medical institution.

Comparison of Medical Education and Requirements for Training in the Interventional Neuroradiology in China, Japan and Korea / 신경중재치료의학

The interventional neuroradiology (INR, or neurointerventional surgery) became a rapidly emerging specialty since the first Working group in Interventional Neuroradiology (WIN) meeting was held in Santa Barbara in 1980 by 15 pioneers. Although the specialty has been led by neuroradiologists, other specialists of neurosurgery and neurology have become involved. Due to diverse background of the specialties with inadequate requirement of education and training, proper level of training standard and quality assurance may be achieved for outcomes of treated patients with neurovascular diseases. In East Asia, there are less inter-relationship of education and training among China, Japan and Korea when compared to the learning opportunities in western countries from the three nations. Therefore, we present the current status and difference of medical education system and compare INR training to improve understanding of INR development in the adjacent countries.

Perspectives on Fellowship Training Standard in Interventional Neuroradiology / 신경중재치료의학

Interventional neuroradiology (INR) is a relatively new clinical subspeciality that uses radiologic imaging, endovascular techniques, and clinical expertise to diagnose and treat diseases involving the central nervous system, head and neck, and spine. Although rapid and successful advances of INR have been achieved in Korea as well as in the world during the past two decades, all of INR procedures still pose a significant risk of misdiagnosis or complication, "the stroke". Accordingly, appropriate and adequate training and experience are essential for the safe performance of these procedures, and minimum program requirements of them must be standardized. However, no recommendations or guidelines for fellowship training and education have been established in Korean Society of Interventional Neuroradiology (KSIN) so far. They must be discussed more and will be established and evolved.

Following the need of specialized development for interventional neuroradiology,more and more problems have arisen and even caused argument in this field. To resolve the issue and promote the healthy and fast development of interventional neuroradiology,it is time for us to formulate the standard training and certification system for interventional neuroradiologist.

Interventional Radiology : Interventional Neuroradiology

Interventional neuroradiology is the catheter-based therapy for vascular lesions of the brain and spine. During the past decade, the field has expanded rapidly, and ongoing technical developments are improving the application, safety, and efficacy of this therapy. A growing number of intracranial disorders are amenable to endovascular interventions, which include aneurysms, vasospasm from aneurismal subarachnoid hemorrhage, arteriovenous malformations, dural arteriovenous fistulas, intracranial tumors, thromboembolic occlusion of intracranial arteries and atherosclerosis. Interventional procedure alone is able to treat patients with diseases that cannot be treated with neurosurgery and radiation ; however, in many cases a combination of these methods provides the best outcome for the patients. Treatment strategies must be developed in collaboration with other neurological sciences and experienced multidisciplinary teams must be responsible for handling of patients with CNS lesions. Both education in practical skill and ethics must be part of structured training programs in especially assigned neurointerventional centers.

Giant Serpentine Intracranial Aneurysm: A Case Report

The authors present a case of giant serpentine aneurysm (a partially thrombosed aneurysm containing tortuous vascular channels with a separate entrance and outflow pathway). Giant serpentine aneurysms form a subgroup of giant intracranial aneurysms, distinct from saccular and fusiform varieties, and in this case, too, the clinical presentation and radiographic features of CT, MR imaging and angiography were distinct.

Successful Management with Glue Injection of Arterial Rupture Seen during Embolization of an Arteriovenous Malformation Using a Flow-Directed Catheter: A Case Report

We present a case in which an arterial rupture occurring during embolization of an arteriovenous malformation of the left occipital lobe with a flow-directed micro-catheter,was successfully sealed with a small amount of glue. We navigated a 1.8-Fr Magic catheter through the posterior cerebral artery, and during superse-lective test injection, extravasation was observed at the parieto-occipital branch. The catheter was not removed and the perforation site was successfully sealed with a small amount of glue injected through the same catheter. Prompt recogni-tion and closure of the perforation site is essential for good prognosis.

Endovascular Treatment of Intracranial AVM / 대한뇌혈관학회지

Since 1983, we have experienced endovascular treatment of intracranial AVMs.2)3) Superselective catheterization of feeding artery, embolization or feeding artery occlusion of the cerebral AVMs have been performed for 73 cases in 134 sessions. Endovascular treatment of intracranial AVMs such as embolization or feeding artery occlusion have been performed for 57 cases of AVMs in 95 sessions. In each time, endovascular approach was performed for two to five feeding arteries, so more than 300 feeding arteries were catheterized by microcatheters or balloon catheters. In this report, we present our experiences of endovascular treatment of intracranial AVMs and discuss embolic materials and the role of endovascular treatment of intracranial. AVMs.
