A case of congenital factor V deficiency is reported. Despite this defect in blood coagulation, the patient had experienced recurrent thrombophlebitis and was referred to us because of deep venous thrombosis of the lower limbs associated with pulmonary embolism. Both functional and immunological assays documented a deficiency of factor V (12 and less than 10%, respectively). The available family members were investigated and the same defect was found in 2 brothers of the propositus, who also suffered from thrombotic diseases (recurrent thrombophlebitis and myocardial infarction). The propositus has been treated with long-term oral anticoagulant therapy, no hemorrhagic complications or thrombotic recurrences being recorded in 2 years' time.

The study of two cases of young patients with renal transplants who, successively and a few months after the procedure, presented a thrombophlebitis of the lower extremities (with or without pulmonary embolism), then an acute coronary insufficiency, without any encouraging or triggering factor, raises the hypothesis that this is not a mere coincidence. In fact, in the literature, numerous cardiovascular risk factors) inherent in complicated chronic renal failure, dialysis, steroid therapy and immuno-suppressive treatment (Azathioprime, under these circumstances) were demonstrated. In addition, abnormalities of the platelets aggregation, hemostasis and fibrinolysis, were at the origin of thrombo-embolic accidents. Besides any specific cardiovascular risk factor or any obvious biological anomaly, there is still a predisposition of patients with renal transplants, to arterial as well as venous thrombo-embolic accidents.

Thrombophlebitis is defined as thrombotic inflammation of a previously healthy superficial vein, varicophlebitis as that occurring in varicosities. The latter appears responsible for the majority of thrombotic venous occlusions. In contrast to venous thrombosis, the thrombotic involvement of deep veins, thrombophlebitis usually resolves without sequel and, in general, thrombophlebitis nor varicophlebitis are associated with the risk of pulmonary embolism. The clinical presentation of thrombophlebitis is that of a tender, hardened superficial vein which, in the presence of inflammation, may be very painful. The lower extremities are most frequently involved. Differential diagnostic considerations include bacterial cellulitis and lymphangitis. The cause of thrombophlebitis, which is rare without precipitating factors, may be a mechanical lesion such as kinking of the vein or trauma to the wall of the vein as well as other primary disease such as auto-immune afflictions, endangiitis obliterans or malignancy; in particular, with localization in the area of the rump, with concomitant occurrence in various regions or extending phlebitis, paraneoplastic syndromes and hemoblastoses should be ruled out. Rarely, phlebitis may be associated with tuberculosis and syphilis. Thrombophlebitis may be caused iatrogenically by improper application of chemical substances which cause damage to the venous walls as well as by indwelling catheters or cannulas. This form can progress to sepsis and pulmonary embolism may be incurred. Varicophlebitis, in contrast, accounts for about 90% of all cases of phlebitis and can be regarded as a typical late complication of varicosities in the superficial venous system.(ABSTRACT TRUNCATED AT 250 WORDS)

Results of the surgical treatment of 147 patients for acute thrombophlebitis of the dilated subcutaneous veins are described. Radical vagotomy was performed in most of the patients. The removal of thrombi from the umbilical veins with the help of the Fogarty probe and aspiration with a vacuum suction device was performed in 13 cases. A conclusion is made that the surgical treatment of acute thrombophlebitis of subcutaneous veins of lower extremities is an effective method of prophylactics of thromboses and pulmonary embolism.

Patients with malignant gliomas are at increased risk for deep vein thrombophlebitis (DVT) and pulmonary embolism (PE). Difficult anticoagulation in cancer patients undergoing surgery, chemotherapy, or radiotherapy limit the choices of therapy for DVT. Interruption of the inferior vena cava with a Greenfield filter is a safe method of treating patients who have malignant gliomas and DVT with PE. We studied 23 patients treated for malignant gliomas; 16 were men and seven were women, with a mean age of 51 years (range, 26 to 78). Five patients had DVT shown by noninvasive blood flow studies, and four subsequently had PE, as demonstrated by ventilation perfusion lung scan; in one patient PE was diagnosed at autopsy. Of the 23 patients, four with postoperative craniotomy had DVT and all four had PE. Two of the five patients who received preoperative chemotherapy had DVT and three had PE. All patients with PE had a Greenfield filter placed in the inferior vena cava via the internal jugular vein without adverse sequelae.

Unsuccessfully treated iliofemoral venous thrombosis can result in pulmonary embolism, phlegmasia cerulea dolens, and post-thrombotic syndrome. Phlegmasia cerulea dolens is characterized by tense swelling of the lower extremity with tenderness of the thigh over the femoral vein, mottling of the limb, and absent distal pulses. Without treatment, phlegmasia cerulea dolens can progress to cause venous gangrene and ultimate limb loss. In the reported case, phlegmasia cerulea dolens developed in a middle-aged woman with metastatic thyroid carcinoma following Greenfield filter placement via the femoral vein after heparinization for deep-vein thrombophlebitis had failed.

In eight of 14 patients who were deficient in protein S and who belonged to two unrelated families thrombosis presented as thrombophlebitis in seven and deep vein thrombosis in six, complicated by pulmonary embolism in four and leg ulcers in two. In four patients superficial thrombophlebitis preceded deep vein thrombosis by one to 11 years. Post-thrombotic varicose veins and venous insufficiency had developed in four patients. In three of those and in a fourth patient symptomatic superficial thrombophlebitis, deep vein thrombosis, and pulmonary embolism did not recur while they were taking oral anticoagulant treatment for six to 12 years. The anticoagulation intensity corresponded to international normalised ratio values of over 2.5. It is concluded that the benefits of anticoagulant treatment for patients with congenital thrombotic disease are great, and thus it is necessary to make an early diagnosis and treat patients at risk of developing thrombosis.

A new abnormal plasminogen, Frankfurt I, has been identified in the plasma of a 42 year-old male patients who had recurring thromboses, thrombophlebitis and pulmonary embolism since his age of 29. Reduced functional and also slightly reduced antigen plasminogen concentrations were found in both the proposituts and his mother. Plasmin generation rates carried out by Streptokinase and Urokinase were also abnormal. The plasmin generated was very unstable in the absence of stabilizing ligands and/or substrates. Crossed immunoelectrophoresis of the purified Frankfurt I revealed a peak with normal size and shape, but displaced with respect to normal Glu-plasminogen toward the anode. Isoelectric focusing followed by zymography on an agarose-fibrin plate proved this observation but did not indicate a separation of the normal from the abnormal plasminogen molecular species, also, fewer bands were found in the abnormal plasminogen isozyme pattern. Kinetic studies of Frankfurt I Glu-plasminogen and plasmin showed that most of the functional abnormality is related to absence of active sites in half of the molecules.

Chronic pulmonary embolism is a rare disease which can occur at first with pulmonary hypertension. In these cases it may be difficult to distinguish between primary pulmonary hypertension. We examined nine patients with Chronic Pulmonary Embolism (CPE) (three females and six males, mean age 45 +/- 13 years, range 21-67 years) and ten patients with Primary Pulmonary Hypertension (PPH) (seven females and three males, mean age 35 +/- 13 years, range 10-56 years) who came to our attention during the years 1973-1986 (mean follow up 3 years). All patients had an electrocardiogram, chest x-ray, echocardiogram, cardiac catheterization with pulmonary angiography; seven patients with CPE and eight with PPH had perfusion lung scans. Progressive dyspnoea was the main feature in all the patients; four out of nine with CPE and none of the ones with PPH had a previous history of thrombophlebitis. In all the patients the electrocardiogram, chest x-ray and echocardiogram showed signs of pulmonary hypertension, so that a clear distinction between the two groups was not possible. Cardiac catheterization showed pulmonary pressure values higher in patients with PPH as compared to the ones with CPE (systolic pressure 96 mmHg vs 70 mmHg, diastolic pressure 49 mmHg vs 31 mmHg, mean pressure 65 mmHg vs 45 mmHg). Pulmonary angiography in more than half of the patients with CPE showed a "cut off" of two or more lobar branches of the pulmonary arteries. In the patients with PPH pulmonary angiography showed a dilatation of the main pulmonary artery and a diffuse bilateral hypoperfusion. Perfusion lung scan in all the cases of CPE showed zonal perfusion defects, while in all cases of PPH, with the exception of one, it was largely normal. Venograms in the districts of the inferior vena cava demonstrated thrombosis in two out of six patients with CPE. Negative venograms were found in the five patients with PPH who had this investigation performed. One patient with CPE had a surgical embolectomy, the other eight had anticoagulant oral treatment. During the follow-up period three patients with CPE and five with PPH died within five years and within fifteen months respectively, of the diagnosis.(ABSTRACT TRUNCATED AT 400 WORDS)
