The Analysis of Missed Diagnosis and Misdiagnosis in the First Imaging Diagnosis of Cerebral Venous Thrombosis / 昆明医科大学学报

Objective To improve the detection accuracy of cerebral venous thrombosis (CVT) in the first imaging examination and to guide the treatment and improve the outcome. Methods Imagings of 17 CVT cases were retrospectively analyzed and the missed diagnosis and misdiagnosis reasons were summarized. Results All the 17 cases were taken CT examination. 7 cases were missed diagnosed and misdiagnosed. 2 of 7 cases were diagnosed as subarachnoid hemorrhage. 1 of 7 cases was diagnosed as the left occipital subacute subdural hematoma. 1 of 7 cases was diagnosed as the right frontal and parietal and occipital lobes cerebral hemorrhage. 1 of 7 cases was diagnosed as the left parietal and occipital lobes cerebral hemorrhage and broken into ventricles. 2 of 7 cases were diagnosed as negative. Conclusion To summerize the reasons of missed diagnosis and misdiag aosis of CVT can improve the detection accuracy in the first imaging examination.

Combined injection of pingyangmycin & dexamethasone for the treatment of maxillofacial and cervical venous malformations / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the therapeutic effect of combined injection of pingyangmycin (PYM) & dexame thasone (DXM) for the treatment of maxillofacial and cervical venous malformations.</p><p><b>METHODS</b>From August 1995 to October 2008, 116 cases with maxillofacial and cervical venous malformations were retrospectively analyzed. The injection dilute was made with PYM 8 mg, DXM 10 mg and 2% lidocaine 2.0 ml (PYM 2 mg/ml). The PYM diluent 1.0-4.0 ml (including the PYM 2-8 mg) was injected into the tumor according to the patients age, tumor size and location. For children, PYM 2-4 mg was injected for one treatment. The needle should be inserted into tumor perpendicularly or from the edge of tumor. After withdrawing blood, the drug was injected into the tumor slowly. The injection could be repeated every 7-10 days. The clinical signs were recorded; ultrasonography and chest X-ray were performed to evaluate the therapeutic effect.</p><p><b>RESULTS</b>1-5 treatments of injection were performed in the 116 patients. The tumor shrinked and disappeared after treatment with PYM 2-40 mg and DXM 5-50 mg. The patients were followed up for 3-5 years with no occurrence and complication.</p><p><b>CONCLUSIONS</b>It's safe, effective and practical to treat maxillofacial and cervical venous malformations by combined injection of PYM and DXM. The cosmetic appearance and function can be preserved at the most.</p>
