1/2. Emergency diagnosis with spiral CT angiography in case of suspected ventral perforation following lumbar disc surgery.BACKGROUND: Ventral perforation and vascular lesions are rare but life-threatening complications in lumbar disc surgery. In some cases, however, it remains unclear from the clinical situation whether a laparotomy is necessary to save the patient. The goal of this study is to demonstrate the value of spiral CT (computed tomography) angiography for emergency vascular diagnosis in two cases. methods: Spiral CT angiography with an intravenous bolus contrast medium injection and reconstruction with images in sagittal, coronal, and oblique planes was performed. RESULTS: Spiral CT angiography confirms or excludes a vascular lesion, as demonstrated in two case reports. CONCLUSION: In unclear cases when ventral perforation in lumbar disc surgery is suspected, the need for emergency laparotomy can be confirmed quickly by noninvasive spiral CT angiography.- - - - - - - - - - ranking = 1keywords = goal (Clic here for more details about this article) |
2/2. Reversible posterior leukoencephalopathy occurring during resection of a posterior fossa tumor: case report and review of the literature.OBJECTIVE AND IMPORTANCE: Our goal was to present a clinically and radiographically documented case of reversible posterior leukoencephalopathy (RPL) that occurred during resection of a posterior fossa tumor. Although RPL has been previously described in multiple nonsurgical settings, we hope that this case description makes RPL more clinically and radiographically recognizable to neurosurgeons. CLINICAL PRESENTATION: RPL is the clinical syndrome of headaches, altered mental status, seizures, and visual loss, with radiographic findings of reversible parieto-occipital changes on cerebral computed tomographic and magnetic resonance imaging scans. It has been previously reported in the settings of malignant hypertension, renal disease, eclampsia, and immunosuppression. To our knowledge, the patient presented represents the first clinically and radiographically documented case of RPL occurring during resection of a posterior fossa tumor. The patient intraoperatively exhibited wide fluctuations in blood pressure and awoke with clinical and radiographic findings consistent with RPL. INTERVENTION: Aggressive intraoperative and postoperative management of the patient's blood pressure, supportive intensive care, rehabilitation, and close radiographic follow-up were performed. CONCLUSION: RPL can occur as a result of intraoperative variations in blood pressure, even among young, previously healthy individuals. With the aforementioned interventions, the patient experienced significant clinical and radiographic recovery.- - - - - - - - - - ranking = 1keywords = goal (Clic here for more details about this article) |
