Editorial: grieving over complications associated with neuro-endovascular treatment

Nagoya university training system for neuroendovascular therapists

SUMMARY

It is very important to train more neuroendovascular therapists (NETists) in response to Japan's growing social needs. Since the supply of qualified NETists is still insufficient to cover Japanese institutions, therefore some emergency cases with indications for endovascular therapy may be overlooked, untreated or treated by other methods resulting in unfavorable outcomes. Thus, neuroendovascular therapies are situated as one of the important tratment modalities for neurosurgical diseases (1,2). We studied our present states of the endovascular neurosurgery and introduce our training system.

Three-Year Retrospective Study of Complications Arising during Interventional Procedures

SUMMARY

This retrospective study aimed to assess the percentage of complications arising in our daily practice of interventional procedures, comparing our findings with those of leading international reference centers and accepted guidelines for endovascular treatment. During the threeyear period considered (2000-2002), we performed 246 interventional procedures, divided into seven different pathological conditions: aneurysms, brain AVMs dural and carotid cavernous fistulae, spine-spinal cord tumours, headneck tumours, carotid stenosis and thrombolysis. Aneurysmal disease accounted for 45% of all endovascular procedures. In conclusion, four periprocedural complications arose in the course of 246 procedures resulting in one death and three cases of permanent neurological deficit (2%).
