Carotid angioplasty and stenting (CAS) for carotid stenosis has been increasingly used as an alternative treatment in patients not eligible for surgery. Even though CAS can be performed relatively simply in many cases, various complications can occur. We report four cases of CAS using the Carotid Wallstent, which were complicated by delayed shortening of the stent, resulting in restenosis after successful CAS.

Any foreign body in the esohagus means an acute danger because of the impending perforation followed by mediastinitis, the impending erosion of bigarteries, and impending aspiration in the care of esorhageal occlusion. Nowadays, foreign body can reliably be removed hy endoscopy, and do not perforate the wall, not changed their form. Complication at the endoscopic extraction of foreign body, that requre surgical intervention are very rare. We presented a case of esophageal foreign body complicated with esophageal ulcer in a 83 years old male.

BACKGROUND: As intravenous thrombolysis (IVT) has very restricted inclusion criteria, eligible patients of IVT constitute a very small proportion and studies about their mortality are rare. The long-term mortality in a patients with contraindication of ineligible patients of IVT still under the debate. So, we investigated the proportion of patients with contraindication of IVT and the short and long-term mortality of them in AIS on emergency department comparing with the long-term effect of IVT in patients with moderate-to-severe stroke.METHODS: Using acute stroke assessment indication registry & Health Insurance Review and Assessment Service database, a total of 5,407 patients with NIHSS≥5 were selected from a total of 169 acute stroke care hospital nationwide during October-December 2011 and March-June 2013. We divided AIS patients into two groups: 1) IVT group who received IVT within 4.5 hours, and 2) non-IVT group who did not receive the IVT because of contraindications. And we divided the subgroups according to the reason of contraindication of IVT. The 5-year survival rate of each group was assessed using Kaplan-Meyer survival analysis.RESULTS: Of the 5,407 patients, a total of 1,027 (19%) patients who received IVT using r-tPA within 4.5 h after onset. Compared with the IVT group, hazard ratios of non-IVT group were 1.33 at 3 months, 1.53 at 1 year and 1.47 at 5 years (p<.001). A total of 4,380 patients did not receive IVT because of the following contraindications to IVT. 1) Time restriction: 3,378 (77.1 %) patients were admitted after 4.5 h following stroke onset, and 144 (3.3%) patients failed to determine the stroke onset time. 2) Mild symptoms:137 (3.1%) patients had rapid improvement or mild stroke on emergency room, 3) Bleeding diathesis or non-adjustable hypertension: 53 (1.2%) patients showed a bleeding tendency or severe hypertension. Compared with the IVT group, the subgroups of non-IVT group showed consistently high mortality during short and long term follow up. Mild symptom and bleeding diathesis or non-adjustable hypertension subgroup in the non-IVT group consistently showed the higher mortality than time restriction subgroup during the short and long-term follow-up (log-rank p<.001). Patients who had rapid improvement or mild stroke on emergency department had the higher mortality than time restriction group in short and long term follow up.CONCLUSION: The AIS patients with rapid improvement or mild stroke on emergency room had higher mortality than ineligible patients of IVT due to time restriction during the short and long-term follow-up. A further management and special support on emergency department is needed for these patients with initially mild stroke and rapid improvement in AIS to reduce the poor outcome.

OBJECTIVE: The operative indications on cerebellar hemorrhage have been controversial especially when the patient condition is grave. Therefore we investigated whether it can be justifiable if we perform the surgery in poor clinical grade. METHODS: Clinical records and computerized tomography(CT) films of the 89 patients, who were undergone hospital treatment due to spontaneous cerebellar hemorrhage between May 1997 and May 2004, were retrospectively researched. RESULTS: The study population consisted of 36 males and 53 female patients. The mean age was 65years (range 23~89). As a result of treatment, the patients, whose Glasgow coma scale(GCS) score were higher, showed better outcomes (p=0.001). 13 patients (14.6%) were below 5 in GCS score and 10 patients of these were operated. Among 10 patients, 4 patients (40%) showed good outcome and 5 patients (50%) had been dead. 3 patients (60%) of these dead patients had the findings of intraventricular hemorrhage, fourth ventricular obliteration and hydrocephalus in CT scan. CONCLUSION: This study suggests that operation may be justifiable in clinically poor grade patient with spontaneous intra cerebellar hemorrhage.

We report a rare case of scalp arteriovenous malformation(AVM). A 55-year-old woman presented with a pulsatile palpable mass on her left temporo-parietal scalp. She complained of insomnia because of bruit, which was audible when she lay on her left side. Computed tomography angiography(CTA) for the scalp vessel showed AVM on the left temporo-parietal region. Multiple enlarged arteries, such as the superficial temporal artery, posterior auricular artery, and occipital artery, were directly connected to the elongated dilated superficial temporal vein. Digital subtraction angiography also showed similar results. Fistulous portions were clearly delineated on both modalities. Surgical excision of the malformations, including feeding arteries and the draining vein, resulted in immediate relief of the symptoms. Usefulness of CTA in the diagnosis of vascular lesions on the scalp was emphasized.

OBJECTIVE: To evaluate the efficacy of balloon guiding catheter (BGC) during thrombectomy in anterior circulation ischemic stroke. METHODS: Sixty-two patients with acute anterior circulation ischemic stroke were treated with thrombectomy using a Solitaire stent from 2011 to 2016. Patients were divided into the BGC group (n=24, 39%) and the non-BGC group (n=38, 61%). The number of retrievals, procedure time, thrombolysis in cerebral infarction (TICI) grade, presence of distal emboli, and clinical outcomes at 3 months were evaluated. RESULTS: Successful recanalization was more frequent in BGC than in non-BGC (83% vs. 66%, p=0.13). Distal emboli occurred less in BGC than in non-BGC (23.1% vs. 57.1%, p=0.02). Good clinical outcome was more frequent in BGC than in non-BGC (50% vs. 16%, p=0.03). The multivariate analysis showed that use of BGC was the only independent predictor of good clinical outcome (odds ratio, 5.19: 95% confidence interval, 1.07–25.11). More patients in BGC were successfully recanalized in internal carotid artery (ICA) occlusion with small retrieval numbers (<3) than those in non-BGC (70% vs. 24%, p=0.005). In successfully recanalized ICA occlusion, distal emboli did not occur in BGC, whereas nine patients had distal emboli in non-BGC (0% vs. 75%, p=0.001) and good clinical outcome was superior in BGC than in non-BGC (55.6% vs. 8.3%, p=0.01). CONCLUSION: A BGC significantly reduces the number of retrievals and the occurrence of distal emboli, thereby resulting in better clinical outcomes in patients with anterior circulation ischemic stroke, particularly with ICA occlusion.

OBJECTIVE: Patients with asymptomatic chronic subdural hematoma (SDH) are prone to fall or slip. Acute trauma on these patients may develop acute subdural bleeding over the chronic SDH. We recently experienced 9 patients with acute-on-chronic SDH. We report the clinical and radiological features of this lesion. METHODS: We retrospectively examined the computed tomographic (CT) scans of 107 consecutive patients who diagnosed as chronic SDH from January 2008 to December 2010. All cases of CSDH were diagnosed on CT with or without MRI scan. RESULTS: Acute-on-chronic SDH is not rare, being 8% of chronic SDH. The most common cause of trauma was a slip in drunken state. Alcoholism with multiple episodes of trauma was one of the prominent histories. Acute-on-chronic SDH appeared as a hyperdense layer of clot with irregular blurred margin or lumps in liquefied hematoma. Single or two burr holes was usually effective to remove the hematoma. CONCLUSION: Repeated trauma may cause acute bleeding over the chronic SDH. It will be helpful to understand the role of repeated trauma as a mechanism of hematoma enlargement.

Acute neurologic deterioration is not a rare event in the surgical decompression for thoracic spinal stenosis. We report a case of transient paraparesis after decompressive laminectomy in a 50-yr-old male patient with multi-level thoracic ossification of the ligamentum flavum and cervical ossification of the posterior longitudinal ligament. Decompressive laminectomy from T9 to T11 was performed without gross neurological improvement. Two weeks after the first operation, laminoplasty from C4 to C6 and additional decompressive laminectomies of T3, T4, T6, and T8 were performed. Paraparesis developed 3 hr after the second operation, which recovered spontaneously 5 hr thereafter. CT and MRI were immediately performed, but there were no corresponding lesions. Vascular compromise of the borderlines of the arterial supply by microthrombi might be responsible for the paraparesis.
