Abstract

The present study retrospectively analyzed the database of the Japanese Registry of Neuroendovascular Therapy 1 and 2 (JR-NET1&2) to determine annual trends, including adverse events and clinical outcomes at 30 days after undergoing neuroendovascular therapy. JR-NET1&2 are surveys that targeted all patients in Japan who underwent neuroendovascular therapy delivered by physicians certified by the Japanese Society of Neuroendovascular Therapy (JSNET) between 2005 and 2009. Medical information about the patients was anonymized and retrospectively registered via a website. Data from 32,608 patients were analyzed. The number of treated patients constantly increased from 5,040 in 2005 to 7,406 in 2009 and the rate of octogenarians increased from 7.0% in 2005 to 10.4% in 2009. The proportion of procedures remained relatively constant, but ratios of angioplasty slightly increased from 32.8% in 2005 to 33.7% in 2009. Procedural complications were associated more frequently with acute stroke (9.6%), ruptured aneurysms (7.4%), intracranial artery disease (ICAD) (5.4%), and arteriovenous malformation (AVM, 5.2%). The number of patients requiring neuroendovascular treatment in Japan is increasing and the outcomes of such therapy are clinically acceptable. Details of each type of treatment will be investigated in sub-analyses of the database.

Abstract

Interventional Neuroradiology (INR) is not bound by the classical limits of a speciality, and is not restricted by standard formats of teaching and education. Open and naturally linked towards neurosciences, INR has become a unique source of novel ideas for research, development and progress allowing new and improved approaches to challenging pathologies resulting in better anatomo-clinical results. Opening INR to Neurosciences is the best way to keep it alive and growing. Anchored in Neuroradiology, at the crossroad of neurosciences, INR will further participate to progress and innovation as it has often been in the past.

Abstract

Restenosis after carotid endarterectomy (CEA) is one of most significant complications. There is no previous report about MRI findings of restenotic lesions and preoperative plaques. The purpose of this study was to evaluate the initial and recurrent plaques in patients with restenosis after CEA by using black-blood MRI (BB-MRI). Three patients who underwent carotid artery stenting for restenosis after CEA were included in this study. The relative signal intensities (rSI) of the initial and recurrent plaques were calculated with reference to the sternocleidomastoid muscle on T1-weighted images (T1WI) and the submandibular gland on T2-weighted images (T2WI). This study investigated the rSI characteristics and morphology of the initial and recurrent plaques. All patients had restenosis within 1 year after CEA. The rSI values of the preoperative lesion were not high on T1WI and were high on T2WI in all cases (T1WI/T2WI: 0.63/2.43 in Case 1, 1.00/1.29 in Case 2, and 1.13/1.70 in Case 3). The morphology of the initial plaques was eccentric in 2 cases and concentric in 1 case. The rSI values of restenosis were high on T2WI in all cases (T1WI/T2WI: 1.09/1.20 in Case 1, 1.31/1.50 in Case 2, and 1.23/1.70 in Case 3). The morphology of restenotic lesions was concentric in all cases. The high rSI on T2WI and concentricity of the restenosis after CEA suggest early restenosis (intimal hyperplasia). The low-iso rSI on T1WI and high rSI on T2WI of the preoperative plaques are associated with restenosis after CEA. BB-MRI may be useful to evaluate and predict restenosis after CEA.

Abstract

Annual retrospective surveys of 20 to 31 medical centers performing endovascular treatment of cerebral aneurysms in Japan from 1997 to 2008 were performed to analyze technical and clinical outcomes of endovascular treatment for ruptured cerebral aneurysm. Patients treated with dome embolization using bare platinum coils within 14 days after onset were retrospectively selected, and clinical features, and technical and clinical outcomes at discharge were studied. Retrospective Endovascular Subarachnoid Aneurysm Treatment (RESAT) 1 covers patients treated from 1997, when the Guglielmi detachable coil was introduced, to 2002, just after International Subarachnoid Aneurysm Trial was reported. RESAT 2 to RESAT 7 were conducted annually between 2003 and 2008. Among 5,624 patients with ruptured aneurysms treated within 14 days after onset, 4,782 patients were treated by dome embolization using platinum detachable coils. The patients in this large retrospective survey included 35.8% aged over 70 years, 36.6% with posterior circulation aneurysms, and 29.3% with poor grades (Hunt and Kosnik grades IV and V). The proportion of patients aged over 70 years tended to increase each year from 33.4% in RESAT 1 to 39.8% in RESAT 7, and the proportion of those with posterior circulation aneurysms decreased from 44.2% in RESAT 1 to 23.8% in RESAT 7 (p<0.001). Overall technical success was obtained in 4,666 patients (97.6%), and favorable clinical outcome (good recovery and moderate disability) at discharge was obtained in 88.0% of grade I-III cases and 73.6% of grade I-V cases. Procedure-related morbidity was 2.9% and mortality was 0.8%. Despite this survey involving high proportions of aged, posterior circulation, and poor-grade patients, the technical success rate and immediate clinical results were relatively favorable. The patient prognosis and aneurysm changes must be investigated over a longer period, together with the effects of the introduction of new endovascular devices for cerebral aneurysms.
