RESUMEN
OBJECTIVE: To report the procedure related complication rate of endovascular treatments (EVTs) performed on patients with aneurysmal subarachnoid hemorrhage (aSAH) under local anesthesia (LA). MATERIALS AND METHODS: This study enrolled 186 patients who underwent EVT for ruptured aneurysm under LA from January 2009 to December 2013. Procedure-related complications rate and factors associated with it were analyzed depending on the patients' factors, aneurysm factors and physician factors. RESULTS: Among the 186 patients who underwent EVT under LA, the respective rates of thromboembolic complication (TEC) and intraoperative rupture (IOR) were 12.8% (23 cases) and 12.9% (24 cases), respectively. Aneurysm size (≥ 7 mm) was the only risk factor for TEC (p = 0.048). CONCLUSION: Compared to previous result with under general anesthesia (GA), the rate of TEC was similar in patients treated under LA, but the IOR rate was significantly higher. The main reason for increasing IOR is considered as the unexpected patients' motion and in accordance with the unexpected movement of the microinstruments. Therefore, another methods to stabilize the patients or switching from LA to GA may be necessary when performing EVT, to reduce complications.

OBJECTIVE: To report effects of the pre-procedural rehydration for reduce thromboembolic complications in acute phase aneurysmal subarachnoid hemorrhage coil embolization. MATERIALS AND METHODS: From January 2009 to December 2013, 190 patients with ruptured aneurysmal subarachnoid hemorrhage (aSAH) treated by coil embolization at our institution were consecutively enrolled in this study. In period 1 (from January 2009 to June 2012, n = 122), pre-procedural fluid was not supplied. In period 2 (from July 2012 to December 2013, n = 68), depending on the state of the patient's body weight and degree of dehydration, intravenous fluid was started with infusion of approximately 7 mL/kg of 0.9 percent saline (minimum 300 to maximum 500 mL) over 30 minutes. RESULTS: A total of 190 patients were hospitalized due to aSAH and underwent coil embolization for five years between January 2009 and December 2013. Of these, 122 patients underwent coil embolization based on the old protocol before June 2012 (period 1) and 68 underwent the procedure based on the new protocol after the period 2. Neck size, width, maximum diameter of the aneurysm and procedure time were associated with procedure related thromboembolic complications in entire periods (multivariate analysis, p < 0.05, in respectively). The frequency of thromboembolism showed a drastic decrease in period 2 (re-hydration period), from 18.0% (22/123) to 4.4% (3/67), which was also statistically significant (p = 0.007, Chi-square test). CONCLUSION: Pre-procedural administration of a sufficient dose of fluid considering the patient's dehydration reduced the frequency of thromboembolism in cases of emergency coil embolization for ruptured aneurysm, without increasing additional specific complications.

We report a case of Brown-Sequard syndrome (BSS) caused by an accidental stab injury of the cervical spine that shows clear magnetic resonance imaging (MRI) findings and clinical presentation. A 42-year-old woman was brought into the emergency department after a stab injury on the right side of the posterior neck from a knife that was lying in a fruit basket after slipping. The patient complained of hemiparesis of the right-side extremities, and ipsilateral hypoesthesia and contralateral sensory loss of pain and temperature were also found on neurological examination. MRI showed a signal change of the C6-7 cord level and the tract of the stab wound through the posterior neck. Irrigation and primary closure of the laceration was performed under the impression of BSS. The neurologic deficit was improved with rehabilitation therapy.
