The most common causes of AAO are large saddle emboli to the aortic bifurcation, in-situ thrombosis of an atherosclerotic aorta, and occlusion of previous surgical reconstruction. We present the case of a 52-year-old female with rheumatic heart disease, ischemic cardiomyopathy with restricted left ventricular function, atrial fibrillation, and previous cardio-embolic stroke, who was brought to the Emergency Department (ED) with sudden-onset dyspnea and lower backache radiating to both the legs. On arrival at the ED, the patient was electively intubated and mechanically ventilated in view of hypoxia and altered mental status, attributed to respiratory failure secondary to acute cardiogenic pulmonary oedema. The secondary survey revealed absence of bilateral femoral and popliteal artery pulsations. A computed tomography (CT) aortogram showed a complete lumen occlusion thrombus in the infra-renal region of the abdominal aorta at the level of L3-L4 lumbar vertebrae. An emergency embolectomy was performed successfully, following which the patient was started on heparin infusion and managed in the Intensive Care Unit (ICU). In the ICU, she suffered a torsade-cardiac arrest, with return of spontaneous circulation (ROSC) following rapid defibrillation. She was extubated on Day 3. Three weeks later, she was discharged from the hospital. At the time of discharge, she had developed ischemic lumbosacral radiculoplexus neuropathy, for which neuro-rehabilitation was advised. In our case report, we would like to highlight the following key points: 1) The importance of a detailed secondary survey in the Emergency Department (ED). 2) An inter-disciplinary approach to a complex syndrome that ensures the highest probability of a good outcome. .展开更多

Literature data were reviewed. Results showed that although EVT is the first choice to AIS-LVO, patients often have poor prognosis. Alberta stroke program early CT score (ASPECTS) based on computerized tomography angiography source image (CTA-SI) can reflect the real cerebral perfusion more truly, and it can assess the size of core infarct more quickly and accurately, thus enabling to judge prognosis.展开更多

All patients underwent a comprehensive ophthalmological examination of both eyes. OH associated with C/HCRVO in patients showing a score >5% for the risk of conversion to primary open angle glaucoma(POAG) was treated with OH medication. The treatment aimed for a decrease in intraocular pressure(IOP) to <21 mm Hg with a >22% reduction from the initial values. The cumulative prevalence of OH and the effectiveness of treatment assessed by the cumulative prevalence of conversion from OH to POAG, were estimated.● RESULTS: Fifteen patients had OH associated with C/HCRVOs, the cumulative prevalence of OH was 29.4%(95% confidence interval, 16.9-41.9). The mean value of the risk score of OH conversion to POAG for the 5 subsequent years was 11.7%±5.4%. The IOP significantly decreased from 25.67±2.16 mm Hg to 18.73±2.96 mm Hg. None of the OH patients converted to POAG during the follow-up period. ● CONCLUSION: The increased cumulative prevalence of OH in C/HCRVO patients indicates that OH is a risk factor for the appearance of venous occlusion. Patients with OH associated with C/HCRVO must be considered to be at high risk for conversion to POAG. Treatment with OH medications prevented conversion to POAG during the 3-year follow-up.展开更多
