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.

The therapeutic effects on pulmonary infarction in 82 cases were reported. The cases were divided into 2 groups: trial group of 60 cases treated with heparin and Chinese herbal medicine Qing Fei decoction (QFD) and control group with antibiotics, cough-remedy, expectorant and treatment for symptomatic relief. The results showed that the resolution rate of pulmonary infarction in the trial group was higher than that of the other group (P less than 0.01). The fading phase of the infarction appeared earlier in the trial group than that in the control group (P less than 0.01). Thrombophlebitis and venous thrombosis were cured simultaneously and the recurrence rate was lower in the trial group than that in the control. Evidences showed that heparin combined with QFD has a excellent effects on the treatment of pulmonary infarction.

The history and physical examination were assessed in 215 patients with acute pulmonary embolism uncomplicated by preexisting cardiac or pulmonary disease. The patients had been included in the Urokinase Pulmonary Embolism Trial or the Urokinase-Streptokinase Embolism Trial. Presenting syndromes were (1) circulatory collapse with shock (10 percent) or syncope (9 percent); (2) pulmonary infarction with hemoptysis (25 percent) or pleuritic pain and no hemoptysis (41 percent); (3) uncomplicated embolism characterized by dyspnea (12 percent) or nonpleuritic pain usually with tachypnea (3 percent) or deep venous thrombosis with tachypnea (0.5 percent). The most frequent symptoms were dyspnea (84 percent), pleuritic pain (74 percent), apprehension (63 percent) and cough (50 percent). Hemoptysis occurred in only 28 percent. Dyspnea, hemoptysis or pleuritic pain occurred separately or in combination in 94 percent. All three occurred in only 22 percent. The most frequent signs were tachypnea (respiration ate 20/min or more) (85 percent), tachycardia (heart rate 100 beats/min or more) (58 percent), accentuated pulmonary component of the second heart sound (57 percent) and rales (56 percent). Signs of deep venous thrombosis were present in only 41 percent and a pleural friction rub was present in only 18 percent. Either dyspnea or tachypnea occurred in 96 percent. Dyspnea, tachypnea or deep venous thrombosis occurred in 99 percent. As a group, the identified clinical manifestations, although nonspecific, are strongly suggestive of acute pulmonary embolism. Conversely, acute pulmonary embolism was rarely identified in the absence of dyspnea, tachypnea or deep venous thrombosis.

We studied 196 patients with suspicion of pulmonary embolism (PE) to evaluate the role of clinical pattern, with special reference to gender and age, in raising the suspicion. Results are that clinical and instrumental patterns, although not specific for PE, may show highly frequent symptoms and signs such as dyspnea (52%), chest pain (60%), enlargement of descending pulmonary artery (49%), diaphragmatic elevation (41%), enlargement of azygos vein (46%) and hypoxia (mean value 68 +/- 13 mm Hg) that allow to suspect PE in most patients and, therefore, to recruit more patients for diagnosis. Moreover, this study shows that gender and age may only partially influence the possibility of raising the suspicion of PE. Indeed, only hemoptysis is significantly (p < 0.02) more frequent in males; only pleuritic chest pain is significantly (p < 0.02) more frequent in youngs; few instrumental findings, such as 'sausage-like' descending pulmonary artery (p < 0.001), enlargement of cardiac shadow (p < 0.01), and hypoxia (p > 0.03) are significantly more frequent in elderly patients. Finally, a characteristic clinical and instrumental pattern of PE may allow to select a subset of patients at higher risk; in fact, previous PE, prolonged immobilization (p < 0.01) and thrombophlebitis (p < 0.001), sudden dyspnea and cough (p < 0.05), 'sausage-like' descending pulmonary artery (p < 0.001), diaphragm elevation (p < 0.02), enlargement of heart shadow, pulmonary infarction and Westermark sign (p < 0.001), S-T segment depression (p < 0.001), and hypoxia (p < 0.001) are findings significantly more frequent in patients with confirmed PE.

An 18 year old man presented with cough and dyspnoea caused by pulmonary infarction. A large friable mass of organising thrombus in an anatomically normal right ventricle was identified as an embolic source. The acute illness was associated with raised titres of anticardiolipin antibodies, one of the antiphospholipid group. This thrombus recurred after surgical removal but subsequently was dissipated after treatment with oral corticosteroids and long-term oral anticoagulation.

We studied 196 patients with suspicion of pulmonary embolism (PE), subsequently confirmed in 98 by positive pulmonary angiography and excluded in 98 by normal or near-normal perfusion lung scan. Patients had a clinical questionnaire for history, and, soon after. a radiograph, blood gas analysis, and an ECG. Clinical and instrumental signs were matched in patients with confirmed and unconfirmed PE to find those more frequent in embolic patients and, thus, more characteristic of PE. The following were: previous PE, immobilization and thrombophlebitis (p < 0.05); dyspnea and cough (p < 0.05); enlarged descending pulmonary artery (DPA), enlarged right heart, pulmonary infarction, Westermark sign (p < 0.001), and elevated diaphragm (p < 0.05); hypoxemia. No ECG sign was more frequent in PE. Thereafter, all variables were processed separately with a logistic multiple regression analysis and those significantly associated to PE were tested in a final logistic model that was able to predict the actual result of angiography or scintigraphy; accordingly, previous PE, immobilization, thrombophlebitis, enlarged DPA, pulmonary infarction, Westermark sign, hypoxemia were significantly associated with a high risk of PE (from 2.8 to 15 times greater than in patients without these signs). Therefore, we may conclude that clinical assessment and noninvasive tests may help to detect patients at higher risk for PE where heparin coverage should be started while waiting for conclusive diagnostic procedures.

Recently the incidence of pulmonary infarction has increased in Japan. The patient was a 67-year-old male who was examined by a local physician for bloody sputum and a cough. A chest X-ray showed a 5-cm mass shadow in the lower left lung area. Bronchofiberscopy and percutaneous needle biopsy were performed, but they did not permit a definite diagnosis, and since the patient had a 13-year history of penile cancer (squamous cell carcinoma), and metastasis or even primary lung cancer could not be completely ruled out, an open chest biopsy was performed. The postoperative histopathological examination allowed a diagnosis of hemorrhagic pulmonary infarction. We report a case of pulmonary infarction resection that was difficult to diagnose preoperatively.

A 21-year-old woman with a 6-year history of ulcerative colitis admitted to our hospital with chest pain, cough and fever of unknown origin in August 1998. On admission, laboratory data showed positive inflammatory signs. A chest radiograph and chest computed tomogram (CT) revealed nodular shadows in the right upper lung field. Fifty days after admission, hypertension developed and a bruit was audible in the neck and the upper abdomen. Digital subtraction angiography showed stenosis in carotid, renal and right upper pulmonary arteries. On the basis of these results, a diagnosis of aortitis syndrome was made. Moreover, these findings indicated pulmonary infarction in the right upper lobe due to aortitis syndrome. Aortitis syndrome preceded by pulmonary infarction involvement is very rare. Autoimmune disorders may have been involved in this case because of the association with ulcerative colitis.

The autopsy protocols of 560 patients were studied in order to detect the incidence of pulmonary embolism, 83 cases were found (15%). The clinical data was analyzed to establish the existence of differentiating points between subjects with pulmonary infarcts and those with embolism but without infarction. The necropsy findings were further scrutinized to determine the effect of the anatomic localization of the embolus upon the production of infarction. Pulmonary infarctions were present in 60% of the cases with pulmonary embolus. The presence of cardiac failure, valvular heart disease and left ventricular hypertrophy was significantly more frequent in patients with pulmonary infarcts. In subjects with or without infarction the age, sex and the presence of medical debilitating diseases, recent trauma, surgical interventions or postpartum, cardiac diseases, arteriosclerotic heart disease, clinical evidence of thrombophlebitis, prolonged bed rest and atrial fibriliation preceding the pulmonary embolism, did not evidenciate any significant difference. In the cases with infarction the pulmonary embolus was significantly more frequently located in the small and sublobar pulmonary artery branches, while when pulmonary infarction was not found the embolic process was more frequently located in the main, right or left pulmonary arteries; occlusion of the lobar arteries had approximately the same incidence in the two groups. The most common clinical signs of pulmonary thromboembolism were dyspnea, tachycardia, cough and shock. The presence of hyperthermia, cough, jaundice, bloody sputum, pleuritic pain, pleural friction rub and pleural effusion was significantly more frequent in those cases with pulmonary infarction; the last five features were present only in the presence of infarction. The electrocardiogram was strongly suggestive of pulmonary embolism in the 6% of all cases, while the chest X-ray in 30% of those with pulmonary infarct. The diagnosis was established antemortem in 40% of the cases with infarction and in 20% of the cases with embolus but without pulmonary infarction. In 23% adequate anticoagulant therapy was established.

A 50-year-old woman reporting sudden-onset chest pain was diagnosed as having pulmonary infarction associated with Takayasus arteritis. She had experienced moderate malaise and cough for 3 months. Computed tomography (CT) and magnetic resonance imaging (MRI) showed wedge-shaped infiltrative shadows typical of pulmonary infarction in the right lung. Although pulmonary artery involvement in Takayasus arteritis is well documented, most patients show only signs of mild to moderate pulmonary hypertension. Few reports discuss patients with symptoms due to pulmonary infarction as the initial manifestation. Takayasus arteritis should therefore be considered a differential diagnosis in pulmonary infarction.
