Blood tests for fibrinogen/fibrin degradation products (FDP/fdp) and soluble fibrin complexes (SFC) were performed in 100 patients at high risk for thromboembolism in order to assess the diagnostic value of these determinations in patients suspected to have pulmonary embolism. Tests were positive significantly less often in high-risk patients, and mean values were significantly lower, when compared with patients with established pulmonary embolism (P less than .001). However, no significant differences existed between high-risk patients and patients with deep venous thrombosis of the legs. Positivity rates and mean values were significantly higher in the presence of pulmonary embolism than in patients with deep venous thrombosis alone (P less than .05). Elevated FDP/fdp and SFC values are useful in the diagnosis of pulmonary embolism in high-risk patients; moreover, positive results in a patient with deep venous thrombosis suggests that pulmonary embolism has occurred.

Out of 112 patients who had a Linton flap operation recurrences developed in 13.3%. The most common causes of it were the incomplete first operation and deep venous thrombosis developing in the follow up period.

Out of 1229 patients operated on according to Harrington there were eight with clinical deep venous thrombosis (DVT) confirmed by phlebography or at autopsy. One patient died from massive pulmonary embolism. All eight DVT were located proximally on the left side. In two cases the first symptom was abdominal pain. At follow-up two patients had slight complaints. One had edema in hot weather and one swelling of the left leg. Another patient had no complaints but venography showed pathological collateral veins. There may be a considerable risk of development of a postthrombotic syndrome.

One hundred sixty patients were retrospectively evaluated to determine the effect of prophylactic inferior vena caval interruption in association with aortic surgery. Sixty-three patients underwent aortic procedures without inferior vena caval interruption and ninety-seven patients underwent placement of an Adams-DeWeese clip as prophylaxis against pulmonary embolism. Pulmonary embolism occurred in 10 per cent of the group without the clip and in no patients in the group with the clip. The incidence of deep vein thrombosis was identical in both groups (10 per cent). The 6 per cent rate of early (within 6 months) postoperative leg edema in the group with the inferior vena caval clip was a significant problem in only one patient after twenty-four months. Prophylactic interruption of the inferior vena cava has been shown to be a safe method of decreasing the incidence of pulmonary embolism without increasing the incidence of venous-related complications.

I have encountered 50 patients with clinical thrombophlebitis involving the lower extremites, with or without associated edema and pulmonary embolism, in whom longstanding self-medication with large amounts of vitamin E appeared to be a significant factor. The majority improved following cessation of vitamin E. In view of the epidemic nature of thrombophlebitis and deep vein thrombosis in the United States, the presumed innocuousness of vitamin E therapy requires reevaluation. Other clinical side effects also have been noted in patients receiving large doses of vitamin E. They include breast tenderness, elevation of blood pressure, a fatigue syndrome, myopathy, intestinal cramps, urticaria, and the possible aggravation of diabetes mellitus. The influence of concomitant metabolic, endocrine, and cardiovascular disorders on the thrombogenic potential of vitamin E is raised, and several possible mechanisms conducive to thrombophlebitis are reviewed.

Using venography as the reference procedure, this study examined the utility of fibrinogen I 125 scanning for the detection or demonstration of deep venous thrombosis. The results demonstrate the inability of leg scanning to detect accurately the presence or absence of thrombi in the deep venous system. Most striking was the lack of sensitivity of this procedure in areas where the propensity for embolization is greatest. Sensitivity is extremely low in the anatomic areas where leg scanning demonstrates reasonable specificity. The results are nearly identical in the extremity not operated upon. The validity of all prior studies relying heavily or exclusively on 125I leg scans to determine the presence or absence of thrombi must be critically reassessed.

A radioimmunoassay (RIA) had been developed for the determination of antithrombin III (AT III) in man. The detection limit was 25 microgram/dl. AT III-RIA level and biological activity (anti-Xa) was significantly correlated (r = 0.737, P less than 0.001). Plasma levels in 36 healthy males (mean +/- SD, 19.9 +/- 2.5 mg/dl) and 21 healthy females (19.1 +/- 2.4 mg/dl) were similar. Serial AT III measurements in normal menstruating females showed lower levels during midcycle and higher concentrations during menstruation. In carcinomas, the AT III levels were lower than normal, particularly in hepatocellular carcinoma. In cirrhosis of liver, the levels were markedly decreased and in some patients were below that found in congenital AT III deficiency. Patients with deep vein thrombosis and patients with heart valve replacement had lower levels than normal, while patients with cerebral vascular occlusion had normal levels. The possible use of AT III as a diagnostic tool of post-operative deep vein thrombosis was demonstrated in one patient after hysterectomy. The increased sensitivity, specificity and precision of this type of assay offer distinct advantages over existing methods of AT III estimation.

Platelet adhesiveness was measured in a total of 589 healthy volunteers and patients. Patients suffered from heart failure, diabetes mellitus, myocardial infarction and deep vein thrombosis have a significant higher platelet adhesiveness as healthy volunteers. The effect of the socalled stressors on platelet adhesiveness was shown in vivo; the same values of platelet adhesiveness were seen as in patients. Therefore it can be concluded that stressors constitute a risk factor in patients with altered vessel walls.

The physician frequently encounters the problems of deep vein thrombosis and pulmonary embolism. Recently, a number of studies have been published which are of considerable help in the management of these disorders. It has been shown that in many cases, low-dose heparin is effective in the prevention of both venous thrombosis and pulmonary embolism. However, once venous thrombosis has already occurred, it is necessary to use full-dose heparin, preferably by the continuous intravenous route, with maintenance of the partial thromboplastin time (PTT) at 1 1/2 times the control at all times. Although monitoring the PTT may not prevent hemorrhage, it will help prevent further thrombosis. Heparin is generally continued for seven to ten days. During this time warfarin is generally begun, and it is important to continue the patient on warfarin for five to seven days while the patient is receiving intravenous heparin therapy. After stopping heparin, oral anticoagulation with warfarin should be continued for six weeks. Then, in the absence of a previous history of venous thromboembolism or a known predisposing condition, it is safe to abruptly discontinue anticoagulation in most patients.

Two hundred patients with suspected deep venous thrombosis had thermography performed prior to ascending phlebography. Diagnostic agreement was obtained in 79%. Published diagnostic thermographic criteria were used; it was not possible to diagnose consistently limited or early thrombosis, especially in the calf muscle veins. Venous insufficiency produced the majority of false positives.
