To assess the usefulness of plasma deoxyribonucleic acid (DNA) detection in the diagnosis of pulmonary embolism (PE), we prospectively studied the frequency and duration of the occurrence of free plasma DNA in 23 patients with PE and in 49 patients with pneumonia, myocardial infarction, thrombophlebitis, or normal lung scans. Plasma DNA was detected in 19 of the 23 patients (83 per cent) with PE and in none of the 49 patients with other diagnoses. Eighteen of the 19 PE patients with free DNA had persistence of DNA on all subsequent sampling for up to 5 days. In this series, plasma DNA had a sensitivity of 83 per cent in the diagnosis of PE and was extremely specific for PE. Thus, detection of free plasma DNA may be useful as a rapid, noninvasive test to aid in the diagnois of PE.

The authors have carried out phlebograms on 50 patients with recent pulmonary emboli. In the majority of cases (44 out of 50) they found thrombosis in the veins of the lower limbs: in 35 cases, these were situated proximally, ending in the femoro-ilio-caval segment; in 9 cases they were confined to the suropopliteal veins. These facts have led us to modify our treatment plan for pulmonary embolism. Thrombolytic treatment seems to be justified in cases where the prebitis is high up, even if the pulmonary embolus is benign. Heparin is reserved for those cases of benign pulmonary emboli which are secondary to suro-popliteal phlebitis. The question of interrupting the inferior vena cava must bed ecided in the light of the phlebograms.

The authors have made a study of the fate of 118 patients with pulmonary embolism. The mortality (21.8%) is related not only to the embolus itself (especially to the recurrent types) but also to the condition of the affected area. Recurrence is common (34%), serious (9 deaths out of 25), and early (during the first three months.). No treatment or inadequate treatment are the main causes. Treatment works effectively on the pulmonary circulation, which becomes reestablished in the majority of cases, but it carries the risk of a high incidence of haemorrhage (29%) which is severe (2 deaths and 10 tranfusions of more than one litre of blood). In the long term, the prognosis is linked to the developments in the lower limbs, in which there is a progressive failure of venous drainage (46 cases out of 57), even in cases in which there was no local sign of phlebitis at the time of the original embolus.

The Doppler Ultrasonic Velocity Detector has been shown to be of significant value in the evaluation of patients with suspected deep venous thrombosis. Our experience in 121 patients demonstrates a false-negative rate of 10% for "minimal" thrombophlebitis and 3.2% for ileofemoral thrombosis when the Doppler was used as a diagnostic aid. Since ileofemoral thrombosis represents the greatest threat to the patient in terms of pulmonary embolism, this appears to be a sensitive and specific technic for the detection of ileofemoral thrombosis.

3.6 g acetylsalicylic lysin was injected into 30 patients daily after operative replacement of the hip-joint. Pulmonary embolism and (or) deep-vein thrombosis were diagnosed in 19 patients. Low-dose heparin (3 X 5000 IU/24 h) significantly reduced the incidence of deep-vein thrombosis (ten of thirty patients: P less than 0.05) compared with the acetylsalicylic acid group. The results demonstrate not only the inadequate thrombosis prophylaxis provided by acetylsalicylic acid, but also that low-dose heparin prophylaxis in these specially at risk patients is of limited efficacy.

The angiographic, scintigraphic, and clinical data of 40 patients were reviewed in order to define the role of 133Xe ventilation studies in the radionuclide detection of pulmonary embolism. Two independent observers interpreted the perfusion images, and several weeks later reinterpreted them in conjunction with 133Xe ventilation studies. Overall diagnostic accuracy was significantly improved (p less than 0.05) when the xenon studies were included. The combined studies were slightly more sensitive and significantly more specific (p less than 0.05) for pulmonary embolism than the perfusion images alone.

A patient with pheochromocytoma presented striking electrocardiographic changes mimicking ischemic heart disease at one time and acute pulmonary embolism at other times. Diffuse left ventricular hypokinesia was demonstrated in the presence of normal coronary arteries. Following removal of the pheochromocytoma, the electrocardiographic abnormalities disappeared.

The influence of several diseases and conditions upon the prevalence of pulmonary embolism in autopsies performed over the July 1, 1964 to June 30, 1974 period at the University of Michigan Medical Center (Ann Arbor, Michigan) were analyzed. The prevalence of pulmonary was 12.3% in the 4600 necropsies in this sample. Patients with pulmonary fat emboli or tumor emboli and patients thought to have thrombosis of the pulmonary artery were not designated as having pulmonary thromboembolism. The patients were categorized with regard to heart disease on the basis of both clinical and necropsy findings. The major factors contributing to an increase in risk of development of pulmonary embolism include heart disease, certain types of cancer, obesity, acute paraplegia and accidental and operative trauma. Other risk factors which could not be assessed in this study include a prior history of venous thromboembolism, pregnancy and the puerperium, use of oral contraceptives, ulcerative colitis and Crohn's disease. Age plays a major role in the prevalence of pulmonary embolism. A portion of the effect of age is related to the age distribution of other diseases contributing to an increased risk, yet advanced age alone may have an independent influence. The risk factors defined should be used in a selective program designed to increase the rate of detection of deep venous thrombosis before pulmonary embolism occurs. Alternatively, patients at increased risk should be treated with prophylactic low dosage heparin during hospitalization.

The case of a young woman, receiving oral contraceptives, who developed massive pulmonary embolism producing circulatory collapse and paradoxical arterial embolism through a patent foramen ovale is documented.. Limb viability was threatened. Emergency management included removal of arterial and pulmonary emboli, surgical closure of the patent foramen ovale, inferior caval partitioning, ovarian vein ligation, and short-term anticoagulation. Recovery was rapid and complete.

Pulmonary embolism with right-to-left intracardiac shunt presents a special problem for the clinician. A review of the literature and 4 personal cases, all diagnosed antemortem, are presented. On the basis of this information certain conclusions are drawn, and we suggest the problem to be a unique indication for the consideration of surgical intervention.
