[Keyhole Approach Endoscopic Surgery versus Stereotactic Aspiration plus Urokinase in Treating Basal Ganglia Hypertensive Intracerebral Hemorrhage].

Objective To compare the short-and long-term effect of two minimal invasive surgical therapies including keyhole approach endoscopic surgery(KAES)and stereotactic aspiration plus urokinase(SAU)in treating basal ganglia hypertensive intracerebral hemorrhage(hICH). Methods The clinical data of 117 hICH patients(63 received KAES and 54 received SAU)were retrospectively analyzed.The operation time,blood loss during surgery,and drainage time were compared between two groups.The residual hematoma volume,hematoma clearance rate(HCR),Glasgow coma scale(GCS)score,and National Institute of Health Stroke Scale(NIHSS)score were recorded at baseline and in the ultra-early stage,early stage,and sub-early stage after surgery.The 30-day mortality and serious adverse events were assessed and the 6-month modified Rankin scale(mRS)score was rated.Results Baseline data showed no significant difference between these two groups.Compared with the SAU group,the KAES group had significantly longer operation time,more intraoperative blood loss,and shorter drainage time(all P<0.001).In the ultra-early stage after surgery,HCR was significantly higher in the KAES group(P<0.001),whereas in the early and sub-early stage,HCR showed no significant differences(all P>0.05).In the ultra-early and early stage,the GCS and NIHSS scores showed no significant differences between two groups(all P>0.05),whereas in the sub-early stage,the NIHSS score was better in the SAU group(P=0.034).The 30-day mortality and incidences of serious adverse events showed no significant difference(all P>0.05).The good recovery(mRS≤3)at 6-months follow-up showed no significant difference between the two groups(P=0.413).Conclusions Both KAES and SAU are safe and effective in treating basal ganglia hICH.In the ultra-early stage after surgery,KAES achieves better residual hematoma volume and HCR,and patients undergoing SAU quickly catch up.The short-and long-term effectiveness of SAU is comparable or even superior to KAES.

Carotid Artery Stenting for the Treatment of Fatal Acute Cerebral Infarction Associated with Aortic Dissection.

Acute aortic dissection (AAD) complicated with acute cerebral infarction lacks a unified treatment plan. We report probably the most effective treatment of a type A AAD with acute cerebral infarction leading to coma. A 43-year-old man presented with acute hemiplegia and unconsciousness. He was diagnosed as acute cerebral infarction. After an ineffective emergency intravenous thrombolysis, a Digital Subtraction Angiography (DSA) examination revealed the severe cerebral artery occlusion, and the TICI 3 level was achieved by stent implantation in the left common carotid artery with significant neurological recovery. A type A AAD was found at the 1 month follow-up ultrasound examination and a further thoracic surgery was performed successfully. Carotid ultrasound is helpful for the diagnosis of AAD from acute cerebral infarction. Carotid artery stenting followed by thoracic surgery is effective in this kind of emergency situations. Further studies are needed to determine the exact indications.

Chinese Military Evaluation of a Portable Near-Infrared Detector of Traumatic Intracranial Hematomas.

Introduction: Secondary brain injury is the main cause of mortality from traumatic brain injury (TBI). One hallmark of TBI is intracranial hemorrhage, which occurs in 40-50% of severe TBI cases. Early identification of intracranial hematomas in TBI patients allows early surgical evacuation and can reduce the case fatality rate of TBI. As pre-hospital care is the weakest part of Chinese emergency care, there is an urgent need for a capability to detect brain hematomas early. In China, in addition to preventing injuries and diseases in military staff and in enhancing the military armed forces during war, military medicine participates in actions such as emergency public health crises, natural disasters, emerging conflicts, and anti-terrorist campaigns during peacetime. The purpose of this observational study is to evaluate in the Chinese military general hospital the performance of a near-infrared (NIR)-based portable device, developed for US Military, in the detection of traumatic intracranial hematomas. The endpoint of the study was a description of the test characteristics (sensitivity, specificity, and positive and negative predictive values [NPV]) of the portable NIR-based device in identification of hematomas within its detection limits (volume >3.5 mL and depth <2.5 cm) compared with computed tomography (CT) scans as the gold standard. Materials and Methods: The Infrascanner Model 2000 NIR device (InfraScan, Inc., Philadelphia, PA, USA) was used for hematoma detection in patients sustaining TBI. Data were collected in the People's Liberation Army General Hospital in Beijing using the NIR device at the time of CT scans, which were performed to evaluate suspected TBI. One hundred and twenty seven patients were screened, and 102 patients were included in the per protocol population. Of the 102 patients, 24 were determined by CT scan to have intracranial hemorrhage. The CT scans were read by an independent neuroradiologist who was blinded to the NIR measurements. Results: The NIR device demonstrated sensitivity of 100% (95% confidence intervals [CI] 82.8-100%) and specificity of 93.6% (95%CI 85-97.6%) in detecting intracranial hematomas larger than 3.5 mL in volume and that were less than 2.5 cm from the surface of the brain. Blood contained within scalp hematomas was found to be a major cause of false-positive results with this technology. Conclusion: The study showed that the Infrascanner is a suitable portable device in Chinese population for detecting preoperative intracranial hematomas in remote locations, emergency rooms, and intensive care units. It could aid military medics, physicians, and hospital staff, permitting better triage decisions, earlier treatment, and reducing secondary brain injury caused by acute and delayed hematomas.

An Acute Ischemic Stroke Resulting from Aortic Dissection.

A 39-year-old man with syncope and persistent dizziness was sent to stroke emergency. Patient's diffusion magnetic resonance imaging of brain showed acute ischemia in right cerebella and right occipital lobe, thus intravenous recombinant tissue plasminogen activator was given to him. However, the patient behaved rather restless with repeated complaint of back and thoracic pain. Further thorax computed tomography angiography confirmed that the underlying cause turned out to be aortic dissection.

Ultra-early versus delayed coil treatment for ruptured poor-grade aneurysm.

INTRODUCTION: The timing of definitive aneurysm treatment (coiling or clipping) in poor-grade (Hunt-Hess IV or V) subarachnoid haemorrhage (SAH) patients has been a controversial topic. The purpose of this retrospective study was to analyse whether ultra-early coiling of ruptured intracranial aneurysms improves the clinical outcomes of poor-grade SAH patients. METHODS: The records of patients with aneurysmal SAH who were treated with endovascular coiling were retrieved. The patients were classified into two groups: group A (patients coiled within 24 h of SAH) and group B (patients coiled ≥ 24 h after SAH). For each group, the patient demographics, Fisher grade, aneurysm characteristics and clinical outcomes were recorded. Outcomes were measured at 6 months using the modified Rankin Scale (mRS). RESULTS: Thirty-one patients were coiled within 24 h of SAH (group A), and fourteen patients were coiled ≥24 h after SAH (group B). Groups A and B had similar clinical and angiographic characteristics. The clinical outcomes showed that a total of 58.1% of the patients (18 of 31) in group A were independent (mRS 0-2) compared with 21.4% of the patients (3 of 14) in group B (P = .028). Univariate analysis demonstrated that ultra-early coiling (P = .028) proved to be an independent predictor of better clinical outcomes (mRS 0-2). CONCLUSIONS: Ultra-early (<24 h after SAH) coiling of ruptured aneurysms was associated with improved clinical outcomes compared to coiling at ≥24 h in poor-grade SAH patients. Larger, prospective studies are required to adequately assess the outcome differences between these two groups.
