PURPOSE: With the increase in the average life expectancy, the elderly population continues to increase rapidly. However, no consensus has been reached on the feasibility for surgical resection due to the high morbidity and mortality rate after surgical treatment in elderly patients caused by aging and underlying diseases. METHODS: This study was performed with patients aged 80 years and older. The subjects were classified into 2 groups as follows: the surgical resection group consisting of 61 patients, and the conservative treatment group consisting of 39 patients suitable for curative resection. RESULTS: Mean age and clinical stages in the conservative treatment group were higher than those in the surgical resection group. There was no significant difference in sex, location of the lesion, histological type, or underlying disease. The mean survival time of surgical resection group and conservative treatment group was respectively 52.1 ± 2.66 months and 37.1 ± 5.08 months (P < 0.05) for clinical stage 1 disease, 41.7 ± 5.16 months and 22.4 ± 6.07 months (P = 0.004) for stage 2 disease, and 31.7 ± 9.37 months and 10.6 ± 1.80 months (P = 0.049) for stage 3 disease. However, as for the extent of lymph node resection for the different stages, we observed no significant difference between the 2 groups. CONCLUSION: Surgical resection in all clinical stages, except stage 4, showed a higher survival rate than conservative treatment. To minimize postoperative surgery complications, limited lymph node dissection should also be considered.

Though exercise T1-201 myocardial perfusion-scintigraphy is an important test in the diagnosis and evaluation of coronary artery disease, this test is limited in cases with poor physical conditions and unstable angina and the physical characteristics of thallium are not ideal for nuclear imaging of the myocardium. Recently, technetium-99m-labelled agent(99mTc-MIBI) has been developed to improved the quality of imaging and for easy usage in myocardial perfusion scan. Therefore, we performed dipyridamole 99mTc-MIBI myocardial scintigraphy and coronary angiography on 25 subjects who were suspeced to have coronary artery disease and the results obtanined were as follows ; 1) The overall diagnostic sensitivity of dipyridamole 99mTc-MIBI perfusion scintigraphy was 73.4%, while specificity was 66.7%. 2) Per vessel sensitivity for coronary artery disease diagnosis by the test was 71.4% and a per vessel specificity for coronary artery disease was 95.7%. 3) In all 75 coronary arteries, LAD had a sensitivity of 66.7%(10/15) and a specificity of 100%(10/10); RCA had a sensitivity of 75%(6/8) and a specificity of 82.4%(14/17); LCX had a sensitivity of 60%(3/5) and a specificity of 100%(20/20). 4) After infusion of dipyridamole, the most frequent adverse effect was chest pain which was seen in 8 cases(32%). The headache was seen in 7 cases(28%). Most of the symptoms were mild in severity and subsided spontaneously but 3 subjects were severe enough to require intravenous administration of aminophylline. In conclusion, dipyridamole 99m2011-06-17Tc-MIBI myocardial perfusion scintigraphy is a useful and safe test for diagnosis of coronary artery disease.

Measurements of ovarian reserve play an important role in predicting the clinical results of assisted reproductive technology (ART). The ideal markers of ovarian reserve for clinical applications should have high specificity in order to determine genuine poor responders. Basal follicle-stimulating hormone levels, antral follicle count, and serum anti-Müllerian hormone (AMH) levels have been suggested as ovarian reserve tests that may fulfill this requirement, with serum AMH levels being the most promising parameter. Serum AMH levels have been suggested to be a predictor of clinical pregnancy in ART for older women, who are at a high risk for decreased ovarian response. We reviewed the prognostic significance of ovarian reserve tests for patients undergoing ART treatment, with a particular focus on the significance of serum AMH levels in patients at a high risk of poor ovarian response.

Objective:
The surgical method for treating spontaneous intracranial hemorrhage (ICH) is not well established despite ICH’s high prevalence and poor prognosis. Minimally invasive surgery has recently received attention; however, literature on this method is scarce. In particular, the appropriate location of the catheter in the hematoma has not been described. We examined whether the catheter position affects the hematoma reduction in a hematoma >50 cc.
Methods:
We investigated the prognoses of 36 patients with ICH who underwent stereotactic aspiration and hematoma drainage using urokinase from January 2010 to December 2018 and the hematoma reduction rates according to the tube position. Two methods evaluated the position of the catheter. In the first method, the hematoma was an imaginary sphere. The center point was set as the operation target. We evaluated the catheter position by determining whether it was in the deep part or the outer part of the half point from that location to the hematoma margin. In the second method, we evaluated whether the catheter was located 1 cm inside the hematoma margin.
Results:
In both the first and second evaluations, there were no differences in age, midline shift, intraventricular hemorrhage status, hematoma volume on admission, Glasgow Coma Scale score on admission, time to operation after symptom onset, and systolic blood pressure. The rates of decrease in bleeding and the prognoses were also not significantly different.
Conclusions
If the catheter is in the hematoma, the rate of hematoma reduction at any position is similar.

OBJECTIVE: Endovascular treatment is one of the most important treatments along with open craniotomy for cerebrovascular surgery. The successful treatment of endovascular disease relies on appropriate instruments and the surgeon's skill. Endovascular treatment needs to provide safe and stable access to the catheter cavity. Additionally, it is important to maintain a round shape without changing to an oval shape. The catheter for endovascular treatment has to be flexible and accommodate at least 0.027 inches of inner diameter. The 6-Fr Navien™ Intracranial Support Catheter (formerly the ReFlex Intracranial Catheter; Covidien Vascular Therapies, Mansfield, MA, USA) provides 0.072 inches of inner diameter. MATERIALS AND METHODS: We reviewed 61 cases for 56 cases of endovascular treatment with a Navien catheter. A triaxial system was used for all procedures with femoral arterial access. The Navien catheter was placed in the petrous segment of the internal carotid artery or third segment of the vertebral artery. The patients had various shapes of intracranial arteries, including tortuous vessels. RESULTS: The Navien catheter was used for 61 cases of endovascular treatment. We had 59 cases of coil embolization at unruptured and ruptured aneurysms and two cases of stent insertion into the middle cerebral artery. All the cases were successful without any catheter-related complications. CONCLUSION: The Navien catheter is a recently developed catheter that has several strengths compared with previously developed catheters. It provides a more stable environment for endovascular treatment. It provides a cavity sufficient for endovascular treatment devices. Additionally, it is sufficiently flexible to approach tortuous vessels.

OBJECTIVE: Researchers and clinicians have been unable to fully elucidate the natural course of and proper treatment for unruptured intracranial aneurysms (UIAs) smaller than or equal to 5 mm, particularly with regard to whether close observation or surgery is more appropriate. In this retrospective study, we evaluated the safety and efficacy of endovascular coil embolization of small (≤ 5 mm) asymptomatic UIAs by analyzing outcomes and complications associated with the procedure. MATERIALS AND METHODS: We analyzed data from 150 patients with small asymptomatic UIAs (≤ 5 mm) treated with coil embolization between January 2011 and December 2015. Three-dimensional angiography was used to measure aneurysm size. We evaluated procedure-related morbidity and mortality, immediate post-operative angiographic results, brain computed thomography follow-up results on post-operative day one, and clinical progress. RESULTS: UIAs occurred primarily in the anterior circulation area (142 cases, 94.67%), though eight patients exhibited UIAs of the posterior circulation. Following coil embolization, aneurysms with complete occlusion were observed in 137 cases (91.3%). Partial occlusion occurred in five cases (3.33%), while the procedure had failed in eight cases (5.33%). Procedure-related morbidity and mortality were five cases (3.33%) and zero cases, respectively. CONCLUSION: The endovascular treatment of small asymptomatic UIAs is associated with good short-term outcomes without permanent neurologic complications as well as low overall complication and morbidity rates. Thus, the procedure should be considered for patients with smaller asymptomatic UIAs.

The azygous anterior cerebral artery (ACA) is a rare type of ACA anomaly. In the conventional angiography, cognition of its realm is difficult without considerable reading. Clinically, misreading its nature causes confusion during the surgical approach to its associated cerebral aneurysm. We report this rare clinical experience with an angiographic and surgical review.

Familial idiopathic basal ganglia calcification(FIBGC) is an inheritable neurological condition characterized by calcium deposits in the basal ganglia and extra-basal ganglia areas. The condition manifests as parkinsonism and other variable neuropsychiatric symptoms. FIBGC is a rare condition, and its pathophysiology has not yet been fully elucidated. Here we report the results of a clinical study of two related patients diagnosed with FIBGC.

OBJECTIVE: A prospective, randomized, controlled clinical study is performed to verify the effectiveness of epidural dexamethasone-soaked gelatin sponges to reduce postoperative pain following lumbar microdiscectomy. METHODS: Twenty-three patients (10 men and 13 women) undergoing lumbar microdiscectomy were included. Five pieces of gelatin sponge measuring 1 x 1 cm (Gelfoam; Pharmacia & Upjohn, Kalamazoo, MI, USA), soaked with either 5mg dexamethasone or an equal amount (2 mL) of saline, were left on the decompressed nerve root after unilateral hemilaminectomy, flavectomy and discectomy. RESULTS: Subjective visual analog scale(VAS) scores of leg pain in the dexamethasone group on the first, third and fifth postoperative days (2.5, 2.5, 1.7, respectively) were significantly lower than in the control group (5.0, 4.8, 3.6) ( P<0.05). No side effects related to the dexamethasone-soaked gelatin sponges were observed. CONCLUSION: The intraoperative application of dexamethasone-soaked gelatin sponges during lumbar microdiscectomy can provide effective postoperative analgesia without complications.

Journal of Korean Neurosurgical Society 2006;39(6):447-450
Cerebral amyloid angiopathy(CAA) is characterized by the deposition of amyloid beta-protein in the walls of small to medium-sized arteries of the leptomeninges and cerebral cortex. While often asymptomatic, CAA can develop into intracerebral hemorrhage facilitated by arterial hypertension. We report the case of a 52-year-old man with CAA and arterial hypertension who developed recurrent cerebral hemorrhages on three different occasions and in multiple non-overlapping loci over a period of nine years. Based on our findings, we recommend brain biopsies for all patients undergoing evacuation of multiple recurrence or atypical pattern intracerebral hemorrhages.
