ABSTRACT

PURPOSE: Emergent intracranial occlusions causing acute ischemic stroke are often related to extracranial atherosclerotic stenosis. This study aimed to investigate the association between post-procedure intracerebral hemorrhage (ICH) and emergent extracranial artery stenting and assess their effects on clinical outcomes in patients with acute ischemic stroke. MATERIALS AND METHODS: We retrospectively analyzed patients undergoing hyperacute endovascular treatment for cervicocephalic vascular occlusion in three Korean hospitals between January 2011 and February 2016. Patients who had extracranial artery involvement and were treated from 24 hours of symptom onset to puncture were included in this study, and they were divided into the extracranial stenting (ES) and non-ES groups. Any type of petechial hemorrhages and parenchymal hematoma was defined as ICH for the current study. RESULTS: In total, 76 patients were included in this study. Among them, 56 patients underwent ES, and 20 patients did not. Baseline characteristics, risk factors, laboratory data, treatment methods, successful reperfusion rates, and baseline stenotic degrees of extracranial internal carotid artery did not differ between these two groups. However, atrial fibrillation was more frequent in patients without than with ES (P=0.002), and post-procedure ICH was more frequent in patients with than without ES (P=0.035). Logistic regression models revealed that ES was independently associated with post-procedure ICH (odds ratio [OR], 7.807; 95% confidence interval [CI], 1.213–50.248; P=0.031), and ICH was independently associated with poor clinical outcomes (OR, 0.202; 95% CI, 0.054–0.759; P=0.018); however, ES itself was not associated with clinical outcomes (OR, 0.530; 95% CI, 0.117–2.395; P=0.409). Notably, ICH and ES had interaction for predicting good outcomes (P=0.041). CONCLUSION: Post-procedure ICH was associated with ES and poor clinical outcomes. Therefore, ES should be cautiously considered in patients with hyperacute stroke.

ABSTRACT

Although many imaging modalities can play some roles in the diagnosis of vertebral artery dissection (VAD), digital subtraction angiography (DSA) remains the gold standard method, with the highest detection rate and ability to assist in planning for endovascular treatment. However, this tool is often avoided in children because its invasive nature and it exposes them to radiation. High resolution magnetic resonance imaging (HR-MRI) have been suggested to be a reliable and non-invasive alternative, but it has never been discussed in children in whom vertebral artery dissection is a rare condition. In this report, we evaluate a case of a 2-year-old child who initially presented with cerebellar symptoms, and was early diagnosed with vertebral artery dissection using HR-MRI and was successfully treated.

ABSTRACT

BACKGROUND: Several nerve blocks can reduce the incidence of postherpetic neuralgia (PHN) as well as relieve acute zoster-related pain, but the long-term outcome of PHN has not been clearly determined. This study investigated the efficacy of selective nerve root block (SNRB) for herpes zoster (HZ) on the long-term outcome of PHN. METHODS: We prospectively conducted an interview of patients who had undergone an SNRB for HZ from January 2006 to December 2016 to evaluate their long-term PHN status. The relationship between the time from HZ onset to the first SNRB and the long-term outcome of PHN was investigated. RESULTS: The data of 67 patients were collected. The patients were allocated to acute (SNRB ≤ 14 days, n = 16) or subacute (SNRB > 14 days, n = 51) groups. The proportions of cured patients were 62.5% and 25.5% in the acute and subacute groups (P = 0.007), respectively. In logistic regression, an SNRB >14 days was the significant predictor of PHN (adjusted odd ratio, 3.89; 95% confidence interval, 1.02–14.93; P = 0.047). Kaplan–Meier analysis revealed that time from the SNRB to the cure of PHN was significantly shorter in the acute group (2.4 ± 0.7 yr) than in the subacute group (5.0 ± 0.4 yr; P = 0.003). CONCLUSIONS: An early SNRB during the acute stage of HZ (within 14 days) appears to decrease the incidence and shorten the duration of PHN, with a median of 5.0 years of follow-up.

ABSTRACT

BACKGROUND AND PURPOSE: Little is known about prognosis after endovascular therapy (EVT) for acute large artery occlusion (LAO) caused by underlying intracranial atherosclerotic stenosis (ICAS). Therefore, we investigated the prognosis following EVT according to the underlying etiology of LAO. METHODS: Patients from the Acute Stroke due to Intracranial Atherosclerotic occlusion and Neurointervention-Korean Retrospective (ASIAN KR) registry (n=720) were included if their occlusion was in the intracranial anterior circulation and their onset-to-puncture time was < 24 hours. Occlusion was classified according to etiology as follows: no significant stenosis after recanalization (Embolic group), and fixed significant focal stenosis in the occlusion site with flow impairment or re-occlusion observed during EVT (ICAS group). Patients were excluded when significant extracranial carotid lesions existed, and when the intracranial occlusion was intractable to EVT so that the etiology was undetermined. The effect of angiographic etiologic classification on outcomes was evaluated using multivariable analysis that was adjusted for potential confounders. RESULTS: Among eligible patients (n=520), 421 and 99 were classified in the Embolic and ICAS groups, respectively. Patients in the Embolic and ICAS groups had similar successful reperfusion rates with EVT (79.6% vs. 76.8%, P=0.537) and 3-month functional independence (54.5% vs. 45.5%, P=0.104). In multivariable analysis, ICAS-related occlusion (odds ratio, 0.495; 95% confidence interval, 0.269 to 0.913; P=0.024) showed poorer 3-month functional independence compared to embolic occlusion. CONCLUSIONS: After EVT, patients with acute ICAS-related occlusion have relatively poor functional outcomes compared to those with embolic occlusion. Novel strategies need to be developed to improve EVT outcomes for ICAS occlusion.

ABSTRACT

BACKGROUND: The intraarticular (IA) injection has become popular for the management of the osteoarthritic knee without an effusion. The success rate of IA injection would be better if it was able to be visually confirmed. We hypothesized that an anterolateral approach, which targets the synovial membrane of the lateral condyle using ultrasound, would provide an equivalent alternative to the anterolateral approach, targeting the synovial membrane of the medial condyle for IA injection of the knee. METHODS: A total of 96 knees with osteoarthritis were randomized placed into the two groups, which were group I (anterolateral approach to the medial condyle) and group II (anterolateral approach to the lateral condyle). The primary outcome was to compare the success rate of the two methods of IA injection. The required length of the needle for injection was also measured and compared. Pain intensity was assessed using the Numeric Rating Scale in order to evaluate the success of injection. RESULTS: There were no significant differences in the success rate between both groups. The success rate of group I and group II were 87.8% (95%, CI 78.7–97.0) and 91.5% (95%, CI 83.6–99.5), respectively (P = 0.549). The needle depth was 5.0 ± 0.8 (3.0 to 6.1 cm) in group I, and 3.0 ± 0.8 (1.5 to 5 cm) in group II (P < 0.001). CONCLUSIONS: The anterolateral approach to the lateral femoral condyle, using ultrasound, is an alternative method to the approach targeting the medial femoral condyle, using shorter needle.

ABSTRACT

BACKGROUND AND PURPOSE: The purpose of the current study is to evaluate the influence of temporal patterns related to the availability of new endovascular treatment (EVT) devices on care processes and outcomes among patients with AIS. MATERIALS AND METHODS: We enrolled 720 consecutive patients (January 2011 to May 2016) in a retrospective registry, ASIAN KR, from three Korean hospitals, who received EVT for acute ischemic stroke (AIS) caused by cervicocephalic arterial occlusions. We performed period-to-period analyses based on stent retriever reimbursement and the availability of second-generation direct-aspiration devices (Period 1: January 2011–July 2014 vs. Period 2: August 2014–May 2016); time metrics and outcomes were compared when the onset-to-puncture time was <720 min among patients with EVT for intracranial occlusion. RESULTS: Period 2 had better post-EVT outcomes (3-month modified Rankin Scale 0–2 or equal to prestroke score, 48.3% vs. 60.2%, P=0.004), more successful reperfusion rates (modified Treatment In Cerebral Ischemia 2b–3, 74.2% vs. 82.2%, P=0.019), fewer subarachnoid hemorrhages (modified Fisher grade 3–4, 5.5% vs. 2.0%, P=0.034) and lower hemorrhagic transformation rates (any intracerebral hemorrhage, 35.3 vs. 22.7%, P=0.001) than Period 1. Compared to Period 1, Period 2 had a shorter door-to-puncture time (median 109 vs. 90 min, P<0.001), but longer onset-to-door time (129 vs. 143 min, P=0.057). CONCLUSION: Recent temporal improvements in post-EVT AIS outcomes in Korea are likely due to a combination of enhanced hospital care processes and administration of newer thrombectomy devices.

ABSTRACT

BACKGROUND AND PURPOSE: The goal of stent retriever-based thrombectomy is removal of embolic clots in patients with intracranial large artery occlusion. However, outcomes of stent retrieval may differ between acute arterial occlusions due to intracranial atherosclerotic disease (IAD) and those due to embolism. This case series describes the outcomes of stent retriever-based thrombectomy and rescue treatments in 9 patients with IAD-related occlusion. METHODS: Among patients who underwent endovascular treatment for acute intracranial large artery occlusion, those in whom stent retrieval was attempted as first-line treatment were included in this review. IAD was defined as significant fixed focal stenosis at the occlusion site, which was evident on final angiographic assessment or observed during endovascular treatment. RESULTS: Median number of stent retriever passes was 2 (range, 1-3), and temporary bypass was seen in all patients. Immediate partial recanalization (arterial occlusive lesion grade 2-3) was observed in 7 patients. Immediate modified thrombolysis in cerebral infarction grade 2b-3 was seen in 6 patients, but the lesions often required rescue treatment due to reocclusion or flow insufficiency. In terms of rescue treatments, angioplasty and intra-arterial tirofiban infusion seemed to be effective. CONCLUSIONS: Our findings suggest that stent retrieval can effectively remove thrombi from stenotic lesions and achieve partial recanalization despite the tendency toward reocclusion in most patients with IAD-related occlusion. Further research into the use of rescue treatments, such as tirofiban infusion and angioplasty, is warranted.

ABSTRACT

PURPOSE: To assess patient radiation doses during cerebral angiography and embolization of intracranial aneurysms across multi-centers and propose a diagnostic reference level (DRL). MATERIALS AND METHODS: We studied a sample of 490 diagnostic and 371 therapeutic procedures for intracranial aneurysms, which were performed at 23 hospitals in Korea in 2015. Parameters including dose-area product (DAP), cumulative air kerma (CAK), fluoroscopic time and total angiographic image frames were obtained and analyzed. RESULTS: Total mean DAP, CAK, fluoroscopy time, and total angiographic image frames were 106.2 ± 66.4 Gy-cm2, 697.1 ± 473.7 mGy, 9.7 ± 6.5 minutes, 241.5 ± 116.6 frames for diagnostic procedures, 218.8 ± 164.3 Gy-cm², 3365.7 ± 2205.8 mGy, 51.5 ± 31.1 minutes, 443.5 ± 270.7 frames for therapeutic procedures, respectively. For diagnostic procedure, the third quartiles for DRLs were 144.2 Gy-cm² for DAP, 921.1 mGy for CAK, 12.2 minutes for fluoroscopy times and 286.5 for number of image frames, respectively. For therapeutic procedures, the third quartiles for DRLs were 271.0 Gy-cm² for DAP, 4471.3 mGy for CAK, 64.7 minutes for fluoroscopy times and 567.3 for number of image frames, respectively. On average, rotational angiography was used 1.5 ± 0.7 times/session (range, 0-4; n=490) for diagnostic procedures and 1.6 ± 1.2 times/session (range, 0-4; n=368) for therapeutic procedures, respectively. CONCLUSION: Radiation dose as measured by DAP, fluoroscopy time and image frames were lower in our patients compared to another study regarding cerebral angiography, and DAP was lower with fewer angiographic image frames for therapeutic procedures. Proposed DRLs can be used for quality assurance and patient safety in diagnostic and therapeutic procedures.

ABSTRACT

BACKGROUND AND PURPOSE: To study the significance of intracranial artery calcification as a prognostic marker for acute ischemic stroke patients undergoing revascularization treatment after middle cerebral artery (MCA) trunk occlusion. METHODS: Patients with acute MCA trunk occlusion, who underwent intravenous and/or intra-arterial revascularization treatment, were enrolled. Intracranial artery calcification scores were calculated by counting calcified intracranial arteries among major seven arteries on computed tomographic angiography. Patients were divided into high (HCB; score > or =3) or low calcification burden (LCB; score <3) groups. Demographic, imaging, and outcome data were compared, and whether HCB is a prognostic factor was evaluated. Grave prognosis was defined as modified Rankin Scale 5-6 for this study. RESULTS: Of 80 enrolled patients, the HCB group comprised 15 patients, who were older, and more commonly had diabetes than patients in the LCB group. Initial National Institutes of Health Stroke Scale (NIHSS) scores did not differ (HCB 13.3+/-2.7 vs. LCB 14.6+/-3.8) between groups. The final good reperfusion after revascularization treatment (thrombolysis in cerebral infarction score 2b-3, HCB 66.7% vs. LCB 69.2%) was similarly achieved in both groups. However, the HCB group had significantly higher NIHSS scores at discharge (16.0+/-12.3 vs. 7.9+/-8.3), and more frequent grave outcome at 3 months (57.1% vs. 22.0%) than the LCB group. HCB was proven as an independent predictor for grave outcome at 3 months when several confounding factors were adjusted (odds ratio 4.135, 95% confidence interval, 1.045-16.359, P=0.043). CONCLUSIONS: Intracranial HCB was associated with grave prognosis in patients who have undergone revascularization for acute MCA trunk occlusion.

ABSTRACT

PURPOSE: The aim of this study was to assess the relationship between serum 25-hydroxyvitamin D3 levels and the severity of atopic dermatitis (AD), markers of atopy (total IgE, total eosinophil count, and eosinophil cationic protein) in AD children according to allergen sensitization. METHODS: This cross-sectional study was carried out on 160 AD patients aged 1 to 18 years between March 2012 and August 2014. The AD patients (AD group) were subdivided into 2 categories according to the results of the allergic skin prick and Unicap tests: the allergic and nonallergic AD groups. We compared 25-hydroxyvitamin D3 levels between the AD and control groups. We also investigated relationships between serum 25-hydroxyvitamin D3 levels, the severity of AD, and markers of AD (total IgE, total eosinophil count, and eosinophil cationic protein) in the allergic and nonallergic AD groups. RESULTS: The average 25-hydroxyvitamin D3 levels were 30.6+/-11.7 and 23.7+/-10.0 ng/mL, respectively, in the control and AD groups (P<0.001). The average 25-hydroxyvitamin D3 levels were 19.7+/-8.6 and 27.5+/-9.8 ng/mL, respectively, in the allergic and nonallergic AD groups, with clinical implications (P<0.001). The 25-hydroxyvitamin D3 levels were not significantly associated with SCORing Atopic Dermatitis index in the allergic (P=0.004, r=-0.092) or nonallergic (P=0.610, r=-0.58) AD groups. The 25-hydroxyvitamin D3 levels were not significantly associated with the aforementioned markers of atopy in the AD group. CONCLUSION: These results suggest that 25-hydroxyvitamin D3 may play a role in the pathogenesis of AD.

ABSTRACT

BACKGROUND: Primary angiitis of the central nervous system (PACNS) is a rare disorder and is often difficult to diagnose due to the lack of a confirmatory test. PACNS can generally be diagnosed based on typical angiographic findings. We describe herein a patient diagnosed with PACNS despite the presence of normal findings on conventional angiography. CASE REPORT: A 44-year-old man with a recent history of ischemic stroke in the right posterior cerebral artery territory developed acute-onset vertigo. Diffusion-weighted imaging revealed an acute infarction within the left posterior inferior cerebellar artery. His medical history was unremarkable except for hyperlipidemia; the initial examination revealed mild gait imbalance. During the 10 days of hospital admission, the patient experienced four recurrent ischemic strokes within the posterior circulation territory (occipital lobe, pons, and cerebellum). He was diagnosed with recurrent cerebral infarctions due to PACNS. The basilar artery exhibited no demonstrable luminal stenosis, but there were direct imaging signs of central nervous system angiitis including wall thickening and contrast enhancement. High-dose intravenous steroid therapy followed by oral prednisolone was administered. There was no further stroke recurrence and follow-up imaging of the arterial walls showed normalization of their characteristics. CONCLUSIONS: The present case emphasizes the importance of wall imaging in the diagnosis and treatment of PACNS.

ABSTRACT

BACKGROUND: Recently, multi-planar reconstruction of the three-dimensional (3D) spiral chest CT scan has demonstrated superiority in the evaluation of the tracheobronchial tree. The goal of this study was to measure the lengths of the right and left main bronchi and their anteroposterior (AP) and transverse (TR) diameters using the 3D and two-dimensional (2D) images in the same adult respectively, and to evaluate the degree of correlation between them. METHODS: We measured the lengths of the right and left main bronchi from the carina to the first of their branches and the AP and TR diameters at the mid-portion of the right main bronchus and 2 cm below the carina in the left main bronchus. We determined the size of the left-sided double-lumen tube (DLT) based on the measured AP diameter of the left main bronchus from the 3D and 2D images, respectively. RESULTS: There was moderate correlation between the lengths of both main bronchi obtained from the 3D images and the 2D images, and between the AP diameter of the left main bronchus obtained from the 3D images and the 2D images. Same sized DLTs were estimated in 69% of the men and 34% of the women. CONCLUSIONS: The lengths of the right and left main bronchi and their AP and TR diameters obtained from 3D images were not strongly correlated with those from 2D images. Therefore, a further study is needed to verify the superiority of 3D images in selecting the appropriate size of left-sided DLT.

ABSTRACT

PURPOSE: Many studies have shown the importance for bronchial hyperresponsiveness (BHR) in children with bronchial asthma and allergic rhinitis. However, studies have not been done in BHR in school age and adolescence with atopic dermatitis (AD). METHODS: The patients with history of bronchial asthma were excluded and methacholine challenge test (MCT) was performed in 103 children with atopic dermatitis. The positive of MCT result is defined as provocative concentration of methacholine causing a 20% fall in forced expiratory volume in 1 second (PC20)< or =8 mg/mL. According of the level of PC20, the patients were divided into two groups. RESULTS: The group 1 (BHR+) was observed in 43 of all patients (41.7%). Of two groups, significant differences were observed in age, body mass index. No significant differences were observed in the number of male, SCORing Atopic Dermatitis (SCORAD) index, admission history, smoking exposure history, other allergic disease, parental allergic disease. The group 1 (BHR+) have higher levels of total eosinophil count compared with the group 2 (BHR-) (629.8+/-360.5/microL vs. 470.2+/-253.9/microL, P=0.01). But no significant association was found between severity of BHR and SCORAD score, total immunoglobulin E, total eosin ophil count and eosinophil cationic protein (r=0.008, P=0.961; r=-0.217, P=0.162; r=0.225, P=0.147; r=-0.032, P=0.841). The list of allergen is that the house dust mite, tree, weed, food, animal hair, and fungus. The house dust mite has correlation with bronchial hypersensitivity statistically and the any of allergen groups, either. CONCLUSION: No significant relationship was observed between degree of BHR and allergy laboratory finding, severity of AD.

ABSTRACT

BACKGROUND: Most morphometric studies of the airway have relied on plain radiographs or CT scan with their attendant limitations. We evaluated the length from vocal cord to carina and diameter of the trachea in adults who had no abnormality of the airway using three-dimensional chest CT scan and compared with demographic data. METHODS: We performed a multiplane reconstruction of the airway using axial, sagittal, and coronal slices (aged 18-87, 100 men, 100 women). We measured that the lengths from vocal cord to carina and the diameters (AP, anteroposterior; TR, transverse) of 50 mm above carina of the trachea. RESULTS: The lengths from vocal cord to carina was 130.2 +/- 11.4 mm in men and 119.5 +/- 10.5 mm in women. The AP and TR diameters of the trachea at 50 mm above carina were men; 18.0 +/- 2.4 mm, 17.2 +/- 2.6 mm, women; 14.4 +/- 2.0 mm, 14.4 +/- 1.9 mm, respectively. The correlation between airway length and age and height was statically significant in men and women but less clinically significant. The correlation between diameter of trachea and height was only statically significant in men but less clinically significant. CONCLUSIONS: This study suggests that these measured data are helpful for the endotracheal intubation and endotracheal tube placement in airway management.

ABSTRACT

Pituitary apoplexy is a rare but life-threatening disorder. Clinical presentation of this condition includes severe headaches, impaired consciousness, fever, visual disturbance, and variable ocular paresis. The clinical presentation of meningeal irritation is very rare. Nonetheless, if present and associated with fever, pituitary apoplexy may be misdiagnosed as a meningitis. We experienced a case of pituitary apoplexy masquerading as a meningitis. A 42-year-old man presented with meningitis associated symptoms and initial imaging studies did not show evidence of intra-lesional hemorrhage in the pituitary mass. However, a follow-up imaging after neurological deterioration revealed pituitary apoplexy. Hereby, we report our case with a review of literatures.

ABSTRACT

OBJECTIVES: The purpose of this study was to investigate whether the age factor would be related with stability of mandibular setback surgery for patients with mandibular prognathism. MATERIALS AND METHODS: We compared the relapse patterns of 47 patients divided into three age groups (termed younger, adult, and older). The younger group consisted of patients between 15 and 17 years old; the adult group was made up of patients between 21 and 23 years old, and the older group was made up of patients more than 40 years old. The positional change of B point was evaluated at preoperative, postoperative, and follow-up states. RESULTS: The horizontal relapse ratio was 21.7% in the younger group, 15.3% in the adult group, and 15.7% in the older group. Although relatively higher degrees of relapse were found in the younger group, this increase was not statistically significant. Spearman's correlation analysis was performed to explore other factors contributing to relapse. We subsequently found that the amount of relapse was related to horizontal setback. CONCLUSION: Although the degree of relapse in younger patients is not significant;y higher compared to other groups. The major contributing factor to relapse after sagittal split ramus osteotomy is amount of setback rather than age when the surgery was performed to patients over than 15 years of age.
