The autopsy findings and clinical features in 60 patients with fatal pulmonary embolism (PE) in University College Hospital, Ibadan, between 1985 and 1989 are analysed in the current study. Pulmonary embolism occurred in 3,8 pc of all autopsied patients during this period. There was a male to female ratio 1,4 to one and average age was 47 years. Malignant neoplasms, infections and cardiac failure were the leading predisposing factors to PE identified. The ante-mortem clinical features consisted largely of non-specific respiratory symptoms of dyspnoea, cough, chest pain and haemoptysis. Of these patients, 15,6 pc were diagnosed ante-mortem as having PE. Pulmonary infarction occurred in 13,3 pc of the cases and was commoner in females and in patients with underlying cardiac diseases. This study emphasises the need for a high clinical index of suspicion to improve the antemortem diagnosis of this potentially fatal condition and to advocate a greater use of prophylactic anti-coagulant therapy in high risk patients.

Major changes have recently occurred in the clinical presentation, diagnosis, and management of primary lesions of the mediastinum. New diagnostic techniques and improved therapy have led to more objective preoperative diagnoses as well as better long-term results. These features are clearly demonstrated in a series of 400 consecutive patients with primary lesions of the mediastinum seen at Duke University Medical Center. Of these, 99 (25%) had a primary cystic lesion. The primary tumors included thymic neoplasms (17%), neurogenic tumors (14%), lymphoma (16%), germ cell tumors (11%), and a miscellaneous group. Malignant neoplasms were present in 166 patients (42%). The anterosuperior mediastinum was the most commonly involved site of a primary cyst or neoplasm (54%), followed by the posterior mediastinum (26%) and the middle mediastinum (20%). Symptoms were present in 62% of the patients and included chest pain (30%), dyspnea (16%), fever and chills (20%), and cough (16%). Of the lesions found on routine chest roentgenograms, 83% were benign. In contrast, 57% of the lesions in symptomatic patients were malignant. Prior to 1967, 94% of asymptomatic lesions were benign, but this figure has now decreased to 76%. Fifty percent of symptomatic patients had a malignant neoplasm before 1967 compared with 62% after that year. Newer diagnostic techniques have greatly enhanced the accuracy of the preoperative diagnosis. They include radioisotopic scanning, monoclonal antibodies, hormonal assay, electron microscopy, fine-needle aspiration biopsy, computed tomographic scans, and magnetic resonance imaging. Each has a definite role and is specifically illustrated as being quite important in this series.(ABSTRACT TRUNCATED AT 250 WORDS)
