An 86-year-old man with previous normal renal function was hospitalized because of renal insufficiency. He had a long history of atherosclerotic heart disease, mild hypertension and pulmonary embolism, requiring anticoagulant therapy. In view of the normal-sized kidneys and absence of casts in the urinary sediment, a diagnosis of atheroembolic renal disease was made. The patient's renal function deteriorated, but he refused hemodialysis. Death occurred within a few weeks. At autopsy, severe aortic atherosclerosis was observed and atheroembolic renal disease was confirmed as the cause of renal failure. Occasionally, renal failure can be the sole manifestation of spontaneous atheroembolic disease. This possibility should be considered if the physician is called upon to establish the diagnosis when renal insufficiency develops in atherosclerotic patients.

Two hundred patients were evaluated retrospectively to determine the clinical effects of prophylactic inferior vena cava (IVC) interruption in association with aortic reconstruction. No pulmonary embolism occurred in the group with IVC interruption, but embolisms did occur in seven of 68 patients who had aortic reconstruction performed without IVC interruption. In two patients, the pulmonary embolism was fatal. Postoperative incidence of deep vein thrombosis was fatal. Postoperative incidence of deep vein thrombosis was 9% in both groups. Clinical and hemodynamic effects of prophylactic IVC interruption were studied in 20 additional patients. Venous hemodynamics (maximum venous outflow, inferior vena cava pressure, and ambulatory venous pressure) showed no change following interruption in 19/20. Sixteen patients from the original group of patients with prophylactic interruption were studied hemodyamically. No pulmonary embolism was clinically evident. One new case of deep vein thrombosis was seen. Again, venous hemodynamics showed no change as a result of IVC interruption. Prophylactic IVC interruption is a safe means of decreasing the incidence of pulmonary embolism without increasing venous-related morbidity.

Fifty-three Hong Kong Chinese patients with fractures of the proximal femur have been studied after hip surgery using functional ascending phlebograms for evaluating deep vein thrombosis. There was an incidence of deep vein thrombosis of 53.1 per cent in the fractured limbs and 14.3 per cent in the uninjured limbs. The majority of thrombi (84.6 per cent) were located in the calf. No clinical or fatal pulmonary embolism was observed.

In a prospective study of 51 patients with fractures of the femoral neck, aspirin was used as a prophylactic measure against thromboembolic disease. Thrombi were detected by cuff impedence plethysmography, Doppler ultrasonography and ascending venography. Thrombi were identified in 20 (39.2%) of the patients. There was no significant difference between the frequency with which thrombi occurred in men and in women. Blood salicylate values were the same for patients who had and who did not have thrombi. There were no instances of pulmonary embolism. The frequency of deep vein thrombosis was comparable to that in a previous series of untreated patients from the same centre. It appears from this study that in these cases prophylaxis against venous thromboembolism using aspirin in a dosage of 600 mg bid is ineffective.

48 patients with acute deep venous thrombosis of the lower limbs were treated with sodium heparin. In 23 patients heparin was injected subcutaneously (s.c.) twice a day and in 25 patients heparin was given by continuous intravenous perfusion (i.v.). Pain and edema disappeared after 8.7 days (s.c.) and 11.7 days (i.v.) respectively. One non fatal pulmonary embolism occurred in each group. A second venography was performed in 24 patients after 7 days of treatment and revealed no difference between the two groups. As judged by repeated thrombin time determination, anticoagulation was ineffective on at least one day in 39% of patients treated subcutaneously and in 60% of patients treated intravenously. The two pulmonary embolisms occurred in patients with ineffective anticoagulation. It is concluded that heparin may be used either intravenously or subcutaneously in the treatment of acute deep venous thrombosis. Thromboembolic complications occurred with both methods of treatment when anticoagulation was ineffective.

Following the operation of the fixation of the vaginal vault by the Williams-Richardson technique a retroperitoneal hematoma was diagnosed and localized in the region of right iliac muscle using computer tomography. The patient has been under heparin therapy because of suspected pulmonary embolism.

In the period 1953 - 1977 there were 223 maternal deaths among 291 800 patients delivered in hospitals under the aegis of the Department of Obstetrics and Gynaecology of the University of Cape Town. A sudden decrease in the maternal mortality rate to below 100/100,000 deliveries occurred in 1956, largely due to the greater use of the obstetric 'flying squad'. Since 1975 maternal mortality rates have been available for the various ethnic groups. For the period 1975 - 1977 the rates were 69/100,000 for Blacks, 40/100,000 for Coloureds and 27/100000 for Whites. Of the deaths, 48% occurred in women aged 21 - 30 years and 29% in those aged 35 years or more. While 28% of deaths were associated with the first pregnancy, grand multiparity (parity 5 or more) accounted for 39%. Nearly half of the patients who died were unbooked. The 7 commonest causes (grouped) of maternal deaths (obstetric as well as non-obstetric) were, in rank order: proteinuric hypertension, haemorrhage, cardiac disease, pulmonary embolism, sepsis, trauma and anaesthetic complications. Proteinuric hypertension is the most important obstetric problem in Cape Town, in terms of numbers of patients, maternal and perinatal deaths, and socio-economic implications for the community. Slightly more than 33% of the infants whose mothers died also succumbed. Major avoidable factors associated with maternal deaths were booking status, grand multiparity, cardiac disease and late or incorrect use of the 'flying squad'.

During the period 1957 - 1977 there were 421 deaths recorded in the gynaecological wards of Groote Schuur Hospital, Cape Town. Nearly 50% of the patients were Coloureds, 25% were Whites, and 14% were Blacks; in 14% the ethnic group was not stated. Seventy-four per cent were more than 40 years and 25% were more than 70 years of age. The causes of death in order of frequency were: malignant disease of the cervix (30%), malignant disease of the ovary (17%), incomplete abortion (15%), non-gynaecological conditions (11%), malignant disease of the corpus uteri (8%), intra-abdominal malignancy (6%), pulmonary embolism (3%), sepsis not associated with abortion (3%), malignant disease of the vulva (2%), and other conditions (5%). The six commonest causes of death varied in the three ethnic groups.

The diagnosis of pulmonary embolism is generally established when the patient has characteristic pulmonary perfusion abnormalities in the setting of an appropriate clinical history and with no concurrent cardiopulmonary disease on chest x-ray film. The initial evaluation, including positive pulmonary perfusion scan, of four young black women suggested the diagnosis of pulmonary emboli. A syndrome of respiratory tract viral infection then developed, and further evaluation by angiography and perfusion scans contradicted the diagnoses of pulmonary emboli. Each patient had substantial convalescent-phase complement-fixation titers to influenza A. Thus, if reliance is placed in pulmonary perfusion scans, an erroneous diagnosis of pulmonary emboli may be made for patients with influenza A.

A brief survey is made of a personal series of 12 embolectomies performed under varying clinical conditions for the management of massive pulmonary embolism. Four satisfactory results were achieved. This operation is carried out under CEC and is a sound procedure. Stress is laid on its fundamental importance in the treatment of cases of this kind. Its early choice should be made in the light of the clinical picture.
