The incidence of deep venous thrombosis (DVT) was studied by the 125I-fibrinogen technique in 70 patients who had had major abdominal operations and who were wearing graduated static compression stockings on one leg, the patient's other leg being used as a control. In the whole group 7 patients developed bilateral DVT, 19 patients developed unilateral DVT in the control leg and only one patient developed unilateral DVT in the stockinged leg. The difference between stockinged and control legs was highly significant (P = 0-0003). In the 19 patients with malignant disease the incidence of DVT in the stockinged leg remained significantly less (P = 0-037). It is concluded that graduated static compression stockings do reduce the incidence of postoperative deep venous thrombosis.

56 patients undergoing elective major surgery received low dose heparin prophylaxis, 5,000 IU 2 h before surgery and every 8 h for 7 days. The patients were tested by the 125I-fibrinogen uptake test, which, if positive, was controlled by venography. The heparin concentrations were measured by the method of DENSON and BONNAR and by the chromogenic method of TEIEN et al. in blood samples drained immediately before and after surgery and on the 1st and 5th postoperative day 2 and 4h after the injection of heparin. The values were found higher when estimated by the method of DENSON and BONNAR than by the chromogenic method. Deep vein thrombosis (DVT) developed in 11 patients, and in 10 of them within the first 48 after the operative procedure, in 1 after 4 days. The preoperative values were not lower in the patients who developed DVT, and the heparin concentrations found on the 1st and 5th postoperative day were at the same level as in those who did not develop DVT.

2136 patients in general surgery, gynaecology and urology were investigated by the 125I-fibrinogen-uptake-test for detection of postoperative deep vein thrombosis (DVT). They received at random one of low-dose heparin, dihydroergotamine, the fixed combination of both drugs (Heparin-Dihydergot), low molecular weight dextran and acetylsalicylic-acid (ASS). When DVT was detected repeated lung perfusion scintigraphies were carried out for diagnosis of embolic pulmonary perfusion defects. Results demonstrate the outstanding effect of Heparin-Dihydergot, which is not only 2-3 times better than the anti-thrombotic standard low-dose heparin but also eliminates almost completely the risk of postoperative embolism. The preventive efficacy of ASS and dextran must be considered to be poor and not comparable to that obtained when using heparin, dihydroergotamine or the combination. Now Heparin-Dihydergot is the new standard with which all prophylactic procedures should be compared.

All studies on the value of acetylsalicylic acid for the prevention of postoperative thromboembolic complications have been evaluated. Controlled, prospective and randomized studies have been analyzed only where the incidence of postoperative deep vein thrombosis or pulmonary emboli was proven by objective diagnostic methods such as the fibrinogen test, phlebography or autopsy. In 6 studies there is no significant reduction in the incidence of deep vein thrombosis in general surgical and orthopedic patients after acetylsalicylic acid prevention. One study, though it has definite methodological defects, does suggest a significant reduction in the number of postoperative fatal pulmonary emboli in 120 patients with fractures of the upper end of the femur. On the basis of all these data, the prevention of postoperative thromboembolic complications by means of acetylsalicylic acid cannot be recommended.

Fifty-one patients with leg symptoms indicating deep venous thrombosis (DVT) were investigated concomitantly with thermography and phlebography. Altogether 26 legs with phlebographically proven DVT exhibited a thermographic picture typical of DVT. So, however, did 3 out of 25 legs with no DVT. A 94 percent agreement was found between phlebography and thermography when applied to legs with suspect DVT. The serum levels of fibrin-fibrinogen degradation products (FDP) were assayed in 58 patients attending hospital for suspect DVT. These patients were free from other diseases known to be followed by raised FDP levels. With borderline significance, the DVT group had higher FDP values. The usefulness of this laboratory test in the diagnosis of DVT is, however, questioned.

Fibrinogen/fibrin degradation products (FDP/fdp) and soluble fibrin complexes (SFC) were measured serially in 60 patients heparinized for pulmonary embolism or deep venous thrombosis. Eight patients had recurrent thromboembolism. In patients without recurrence, FDP/fdp and SFC tended to normalize within three to five days. In patients with recurrence, results of both tests were significantly higher on admission, and FDP/fdp values were significantly higher throughout ten days of therapy, than in patients without recurrence. The SFC values were not different between the two groups during the first six days of treatment, but again became significantly higher on the seventh day in patients with recurrence. There were no differences in clotting times, heparin dosage, or any other clinical features between patients with and without recurrence. Measurement of FDP/fdp and SFC can help identify patients at risk of recurrent thromboembolism if performed serially during treatment.

Unmatched perfusion defects occur during the early postoperative period. These defects can persist until the tenth postoperative day and their presence is not related to the transfusion of blood or to peripheral thrombosis detected by the 125I-labelled fibrinogen uptake test. It is suggested that prophylactic agents against deep venous thrombosis should be evaluated by using a combination of krypton ventilation-perfusion lung scans and 125I-labelled fibrinogen leg scans.

The 125I-labelled fibrinogen test has been used to assess the incidence of deep venous thrombosis in 88 patients who had undergone elective aorto-iliac reconstruction. Deep venous thrombosis was detected in 18 (20.5 per cent). The results suggest that these patients merit prophylaxis.

Small doses of subcutaneous heparin and infusions of dextran both reduce the incidence of fatal pulmonary embolism after elective general surgery. But both methods have disadvantages. Therefore, the protection against deep vein thrombosis afforded by sulfinpyrazone, a drug which can be taken by mouth as well as by injection, was assessed in a prospective study of 119 patients undergoing elective general or urological surgery. The prophylactic administration of sulfinpyrazone was compared with the effects of small doses of sodium heparin and infusions of dextran-70. The 125I-fibrinogen test was carried out in all patients during their hospitalization. Deep vein thrombosis was diagnosed in 13 of 30 patients (43%) who received sulfinpyrazone, in 9 of 29 (31%) receiving dextran-70 and in 2 of 22 (9%) having subcutaneous heparin. The difference between the sulfinpyrazone and heparin groups was statistically significant (p less than 0.01). Sulfinpyrazone in the dose used in this trial was not effective in reducing the incidence of deep vein thrombosis during elective general surgery.

Twenty acute spinal cord injury patients were surveyed for deep venous thrombosis (DVT) by 125I fibrinogen leg scanning, impedance plethysmography (IPG), and venography. Leg scanning was a more sensitive indicator of thrombotic events than IPG or venography. IPG was a reliable indicator of accumulated thrombosis. The incidence of dvt assessed by leg scanning alone was 100 per cent. Its occurrence as determined by either of the screening techniques was found to be considerably greater than those of previous reports.
