SUMMARYSpontaneous coronary artery dissection is a rare cause of acute coronary syndrome. It is most commonly seen in young women, without atherosclerosis, in the peripartum period. Management options include conservative medical treatment, percutaneous coronary intervention or a surgical approach depending on the presentation, extent of dissection and luminal stenosis. We describe three unusual cases of spontaneous coronary artery dissection occurring in young/middle-aged men-the first in association with heavy mechanical work, the second in association with high levels of anxiety and emotional distress and the third in association with intense physical exercise. In each case we report the use of coronary angiography and intravascular ultrasound in the diagnosis of the condition, and their successful management using percutaneous coronary intervention.
BACKGROUND
BackgroundSpecific procedural complications in aneurysm surgery are broadly related to vascular territory compromise and brain/nerve retraction; vascular complications account for about half of this. Intraoperative indocyanine green video angiography (ICG-VA) provides real-time high spatial resolution imaging of the cerebrovascular architecture, allowing immediate quality assurance of aneurysm occlusion and vessel integrity. The aim of this study was to examine whether the routine use of ICG-VA reduced early procedural complications related to vascular compromise or injury during micro-neurosurgical clipping of ruptured cerebral aneurysms.MethodsRetrospective comparative observational study of 412 adult good-grade (WFNS 1 or 2) SAH patients who had undergone microsurgical clipping without (n = 200, 2001–2004) or with (n = 212, 2009–2015) ICG-VA in a high-volume neurosurgical centre.ResultsThe ICG-VA group had a significantly lower incidence of procedural vascular complications (7/212; 3.3%) compared with the non-ICG-VA group (19/200; 9.5%) (Fisher’s exact test p = 0.0137).ConclusionsICG-VA is a straightforward, easy-to-use, intraoperative adjunct which significantly reduces avoidable ‘technical error’ related morbidity.
Background:
Myxopapillary ependymoma occurs more frequently in adults, but is found in the first two decades of life in around 8–20% of patients. Tumors are usually benign with low likelihood for dissemination.
Case Description:
We describe a case of a 13-year-old boy who presented with progressive kyphosis and bilateral weakness of the lower limbs. MRI shows a thoracolumbosacral intradural tumor with invasion of sacral neural foramina and dissemination to the cervicothoracic region. The patient received T10-L5 laminectomy with subtotal tumor resection. Pathological examination revealed myxopapillary ependymoma. After surgical resection, the patient underwent physical therapy with whole spinal radiotherapy for disease control.
Conclusion:
Spinal myxopapillary ependymomas are usually benign and slow-growing tumors. This case illustrates an extensive and disseminated myxopapillary ependymoma.
