[Assessment of mental condition and anxiety in patients receiving neuroendovascular treatment].
OBJECTIVE
Neuroendovascular treatment (NET) is an effective and minimally invasive procedure used for patients with vascular disease of the central nervous system. The purpose of this study was to examine anxiety levels using standardized psychometric tools and an original questionnaire among patients before and after NET.


METHODS
A total of 40 patients who underwent NET were included. There were 18 patients with unruptured cerebral aneurysm, 18 with carotid stenosis, and 4 other cases. Patients were asked to complete a State-Trait Anxiety Inventory (STAI) and also to fill out a questionnaire about perioperative anxiety. It elicited the following information: (a) state-anxiety score and level before and after NET; (b) trait-anxiety score and level before and after NET; and (c) perioperative anxiety about NET. In all cases, the procedure was performed under local anesthesia.


RESULTS
The preprocedural state-anxiety score was high in many patients (82%). The principal cause of the preprocedural anxiety was the procedure-related complications (92%). Patients with cerebral aneurysm experienced anxiety during the procedure because they could not know which stage of the procedure was involved. Their state-anxiety score was improved in the postprocedural examination (88%). However, patients were still anxious about postoperative complications and recurrence, particularly those with cerebral aneurysm. Patients with cerebral aneurysm generally tended to experience a higher level of anxiety than those with carotid stenosis.


CONCLUSIONS
Though NET is apt to be thought as a relatively easy procedure, patients actually felt much anxiety, especially those with cerebral aneurysm. Due care for perioperative anxiety in patients who undergo NET is important.
