OBJECTIVE: Spontaneous intracerebral hemorrhage (ICH) in young adults is rare. The purpose of this study was to investigate causes, sites and other factors affecting the prognosis of ICH in young adults aged < or = 40 years. METHODS: We reviewed 39 consecutive patients diagnosed with spontaneous ICH between January 2001 and June 2012. Patients with primary subarachnoid hemorrhage, previously diagnosed brain tumor bleeding, or vascular malformation were excluded. We analyzed the differences in prognostic factors such as hemorrhage location and vascular structural etiology. The outcome was measured using the Glasgow outcome scale (GOS), and a good outcome was defined as a score of 4 or more. RESULTS: We retrospectively evaluated 39 patients (mean age, 33 years; SD = 6.4, range 17 to 40 years). The most common structural etiology was arteriovenous malformation. A statistically significantly higher proportion of patients with good outcomes had a lower initial systolic blood pressure (SBP < or = 160 mmHg, p = 0.036), a higher initial Glasgow coma scale (GCS) (9 or more, p = 0.034), lower cholesterol levels (< 200 mg/dl, p = 0.036), and smoking history (at discharge, p = 0.008; 6 months after discharge, p = 0.019). CONCLUSION: In this study, cryptogenic ICH was the leading cause of spontaneous ICH. A GCS score of 9 or more on admission, a lower serum cholesterol level (< 200 mg/dl), and a lower SBP (< 160 mmHg) predicted a good outcome.

OBJECTIVE: To assess the results of superficial temporal artery-middle cerebral artery anastomosis (SMA) in atherosclerotic disease (ASD) and in adult moyamoya disease (MMD) by comparing the complications that arise. METHODS: We retrospectively reviewed patients with ASD or adult MMD treated by means of SMA, between December 2004 and December 2006, at our neurovascular center. During this period, we performed 115 SMAs on 108 patients: 61 on ASD patients (61 SMAs; the ASD group) and 47 on adult MMD patients (54 SMAs; the MMD group). RESULTS: We found a higher incidence of permanent neurological deficits (PNDs) and a lower incidence of transient neurological deficits (TNDs) in the MMD group than in the ASD group (p-value=0.047). Patients with a preoperative stroke (cerebral infarction/hemorrhage) history were more likely to develop postoperative PND than were the patients with a preoperative history of transient ischemic attack (TIA), in both the ASD (p-values=0.012 and 0.033, respectively) and MMD groups (p-values=0.000 and 0.015, respectively), regardless of overall patients (n=108) and single SMA group (n=62). Delayed seizure (seizure occurring > 1 month after SMA) occurred only in 8 MMD patients (8/47, 17.0%; p-value=0.003) out of all 108 patients and in 2 patients (2/10, 20%, p-value=0.014) out of the single SMA group. CONCLUSION: Regardless of whether the diagnosis is ASD or MMD, patients with TIA preoperatively seem more prone to develop postoperative TND, and patients with a stroke history seem more prone to develop PND in both ASD and MMD groups. However, MMD patients appear more likely to experience a delayed seizure attack after SMA than ASD patients are.

Superior petrosal sinus (SPS) dural arteriovenous fistula (DAVF) is one of tentorial DAVFs with significant morbidity, which usually drains into the petrosal vein and its tributaries. Unless there is a connection with venous sinus, surgical obliteration is required. We present two cases of SPS DAVF which were successfully treated with the presigmoid retrolabyrinthine approach.

Pulmonary artery hypertension is a common cardiovascular complication in preterm infants with bronchopulmonary dysplasia which is associated with increased morbidity and mortality. Inhaled iloprost is used as a therapeutic option in pulmonary hypertension, especially in adults. There have been but a few reports on the use of iloprost for neonates and infants. We report the case of a 5 month-old-male infant who received neonatal intensive care for 4 months due to respiratory distress syndrome and prematurity, during which he developed bronchopulmonary dysplasia. Echocardiography showed severe pulmonary hypertension. The initial treatment included respiratory support with high frequency oscillatory ventilation (HFOV); however, his clinical condition did not improve. Inhaled iloprost with sildenafil, an oral phosphodiesterase-5 inhibitor, was thus used. With the administration of iloprost and sildenafil, his condition improved and he was weaned from oxygen. Our clinical experience suggests that iloprost is a promising therapy for pulmonary hypertension, especially when inhaled nitric oxide is unavailable.

PURPOSE: When pneumothorax occurs during a percutaneous needle biopsy, the radiologist usually stops the biopsy. We evaluated the usefulness of computed tomographic (CT) fluoroscopy-guided percutaneous needle biopsy in the presence of pneumothorax during biopsy. MATERIALS AND METHODS: We performed 288 CT fluoroscopy guided percutaneous needle biopsies to diagnose the pulmonary nodules. Twenty two of these patients had pneumothorax that occurred during the biopsy without obtaining an adequate specimen. After pneumothoax occurred, we performed immediate CT fluoroscopy guided percutaneous needle biopsies using an 18-gauge cutting needle. We evaluated the success rate of the biopsies and also whether or not the pneumothorax progressed. We classified these patients into two groups according to whether the pneumothorax progressed (Group 2) or not (Group 1) by measuring the longest distance between the parietal pleura and the visceral pleura both in the early and late pneumothorax. Additionally, we analyzed the relationship between the progression of pneumothorax after biopsy and 1) the depth of the pulmonary nodule; 2) the number of biopsies; 3) the presence or absence of emphysema at the biopsy site; and 4) the size of the pulmonary nodule. RESULTS: Biopsy was successful in 19 of 22 nodules (86.3%). Of the 19 nodules, 12 (63.2%) were malignant and 7 (36.8%) were benign. Twelve patients (54.5%) were classified as group 1 and 10 patients (45.4%) as group 2. The distance between the lung lesion and pleura showed a statistically significant difference between these two groups: < or = 1 cm in distance for group 1 (81.8%) and group 2 (18.2%), and > 1 cm in distance for group 1 (30%) and group 2 (70%), p < 0.03. Yet the number of biopsies, the presence or absence of emphysema at the biopsy site and the size of the pulmonary nodules were not related to the progression of pneumothorax (p > 0.05). CONCLUSION: When early pneumothorax occurs during a biopsy, CT fluoroscopy guided percutaneous needle biopsy is an effective and safe procedure. Aggravation of pneumothorax after biopsy is affected by the depth of the pulmonary nodule.

Transient cortical blindness is a rare but well-recognized complication of cerebral angiography. A 62-year-old woman with unruptured cerebral aneurysm and a 16-year-old boy with cerebellar hemangioblastoma experienced blindness after diagnostic cerebral angiography and tumor embolization, and the symptom resolved after 1 hour and 36 hours later, respectively. We report two cases of this complication.

BACKGROUND AND OBJECTIVES: Benign paroxysmal positional vertigo (BPPV) is one of the critical life events that can affect physical, emotional, and functional aspects of quality of life. Canalith repositioning procedure (CRP) provides rapid and long lasting relief of symptoms in most patients with BPPV. However, some patients express nonspecific symptoms such as anxiety or discomfort after treatment, The purpose of this study was to assess the residual symptoms after CRP in patients with BPPV using Dizziness Handicap Inventory (DHI) in a questionnaire format and to evaluate the therapeutic efficacy of CRP according to accompanying the DizzyFIX device. MATERIALS AND METHODS: We performed a prospective investigation in 135 consecutive patients with confirmed posterior semicircular canal BPPV. CRP was performed until nystagmus and vertigo disappeared. Patients were divided into three group using the DizzyFIX (group A), not using the DizzyFIX (group B) and closed observation (group C) after treatment. Then patients were asked to complete the questionnaire for Korean form DHI before treatment, 1, 2, 3, 4, and 8 week after treatment. RESULTS: There was a significant improvement in DHI scores when comparing the pre CRP and post CRP three groups (p<0.05), although emotional items showed incomplete improvement at 1 week. But at 2 week after treatment, there were statistically significant differences between group A and other groups in DHI scores specially in emotional items. CONCLUSION: Even after successful CRP, DHI scores indicated incomplete recovery and residual subjective symptoms may remain. For these patients additional follow up and management are necessary and using of the DizzyFIX will be helpful to reduce the incidence of residual dizziness especially emotional aspect.
