During the years 1975 through 1989, 189 patients have been operated because of metastases within bones of the lower extremity. Thereof, 34 patients received an endoprosthesis of the KMFTR (Kotz Modular Femur-Tibia reconstruction system) type. In detail, the following reconstruction elements had been used: proximal femur (n = 20), distal femur (n = 7), complete femur (n = 2), proximal tibia (n = 5). At the time of follow-up examination 30 patients had died. Mean survival time after resection of metastases was 18.6 months (range 8-44 months). According to histologic judgement, in 23 cases wide or marginal resections had been performed whereas 11 patients had been operated intralesionally. In no case local recurrence as relevant to therapy was observed. At the same time-point, survival periods after detection of secondary manifestations of the malignant diseases within the remaining 4 patients were 29, 61, 73 and 125 months, respectively. The following complications were observed: luxation of the prosthesis (n = 6), transient paresis of the peroneus (n = 3), deep vein thrombosis (n = 2), pulmonary infarction (n = 1), wound healing disturbances (n = 2) and hematoma (n = 3).

To assess the incidence, risk factors, and clinical importance of deep vein thrombosis in acute stroke, we studied 70 consecutive patients who underwent hemostasis screening at the time of entry into the study and followed up these patients with serial venous Doppler examinations and the iodine 125-labeled fibrinogen uptake test. Mortality was significantly higher among the 20 patients who developed a deep vein thrombosis, and eight of them had necropsy evidence of pulmonary embolism. Severity of leg paresis and a shortened activated partial thromboplastin time were significantly associated with subsequent deep vein thrombosis with multivariate analysis. Significantly higher levels of fibrinopeptide A were found in patients with postmortem evidence of pulmonary embolism. Deep vein thrombosis is a frequent complication of acute stroke and may influence the prognosis by inducing pulmonary embolism. Our findings allow rapid identification of high-risk patients who may benefit maximally from prophylactic treatment of venous thromboembolism.

Pulmonary embolism secondary to deep vein thrombosis is a frequent cause of death in stroke patients. In a multicentre study of deep vein thrombosis prophylaxis, 112 patients with cerebral infarction and leg paresis were given aspirin 300 mg three times a day (t.d.s.) alone or with dipyridamole 100 mg t.d.s. To screen for deep vein thrombosis liquid crystal thermography of the legs was performed daily for 15 days on all patients. Those patients with positive thermography underwent immediate X-ray venography of the appropriate limb as the definitive investigation for venous thrombosis. Twenty-two patients had positive thermograms, of whom 16 had confirmed deep vein thrombosis as demonstrated by X-ray venography. Only 8 of the 22 had clinical signs of deep vein thrombosis and 2 of those had a negative venogram. Of the 14 patients with positive thermography but negative clinical signs 10 had positive venograms. Difference in the incidence of deep vein thrombosis in the two treatment groups was not demonstrated. It is concluded that occult deep venous thrombosis is common after ischaemic stroke and it can occur without clinical signs. Liquid crystal thermography is a simple, rapid and cheap screening test that will allow the detection of clinically unrecognized thrombosis.

In a prospective study of the incidence of deep vein thrombosis (DVT) after stroke, and the prophylactic effect of dextran, 50 patients, admitted with a diagnosis of cerebral infarction with paresis of the lower extremity within the first 48 hours, were randomly allocated to treatment or non-treatment groups. The treatment group received 500 ml of dextran 40 on admission and on days 1 and 2, and 250 ml on days 4 and 6. Venesection was performed on admission and if necessary on day 1. The control group received no dextran or venesection. DVT was diagnosed with the 125I-fibrinogen test during the first ten days. The incidence of DVT was 54% in the treatment group and 50% in the control group. There were no statistically significant differences between the groups regarding number of DVTs needing treatment, number of positive scanning points or number of days for scan to become positive. Lethal pulmonary emboli occurred in one treated and in three control patients, respectively. Age and progress of neurologic symptoms predisposed for the development of DVT. The high incidence of DVT in stroke patients indicates the need for prophylactic routines.

143 patients with acute onset of hemiplegia transferred to our unit for rehabilitation were analysed retrospectively for the development of deep vein thrombosis or pulmonary emboli. 26% of the patients had suffered thromboembolic events, in more than half of the cases within the initial four weeks after hospital admission. Hemiplegia seems to be the main risk factor for thromboembolic complications, whereas age and sex had no further impact on the rate of occurrence in our series. Nor did we find a correlation between the extent of the paresis in the involved lower extremity or the degree of restriction of mobility and the incidence of thromboembolic disease. Because of the high frequency of thromboembolic complications in our patients we recommended prophylactic treatment with low dose heparin given subcutaneously, followed by oral anticoagulant therapy with vitamin K antagonists, provided there are no contraindications.

The clinical diagnosis of deep venous thrombosis is difficult: "signs of thrombosis" described by Homan are not reliable. Edema in the subfascial compartment, livid discoloration of the skin, congested foot veins in the upright position and the search for potential superficial collateral veins provide a more accurate diagnosis. It must be realized, however, that in about one third of the patients there will be unavoidable errors which include hematomas in the muscle compartments, posttraumatic swelling, compression of the veins by tumors, aneurysms or cysts, acute forms of lymphedema, erysipelas, and insufficiency of muscle pump in paresis. Non-invasive tests (Doppler-ultrasound, plethysmographic techniques) increase diagnostic accuracy of 80-95% provided that the thrombosis affect iliac or femoral veins. In the leg region only phlebography and the test using labelled fibrinogen are sufficiently accurate. The diagnostic steps are described in detail. They depend in part on local facilities, severity of disease and the therapy planned (anticoagulation alone, fibrinolysis, thrombectomy). The better the left expectancy and the severe the symptoms, the more thorough must be the diagnostic measures, including phlebography with a view to possible removal of the thrombi by medical or surgical means.

Acute arterial occlusions of the extremities present with the classical five P's: pain, pallor, pulselessness, paresthesia, paresis. Loss of sensitivity and motility are symptoms of the most severe grade of ischemia. The occlusions are due to embolism in about 70% of subjects and to local thrombosis in 30%. These patients have to be treated immediately with heparin. In the mildest forms, deobliteration is desirable, but in the more severe cases rapid restoration of flow not only saves limbs but also life. Deobliteration may be performed surgically or by means of catheters (local thrombolysis or thrombus aspiration) if available. Deep vein thrombosis, the other kind of emergency situation, requires immediate anticoagulation as soon as pulmonary embolism is suspected. It should be initiated by heparin and followed by oral anticoagulation. In patients presenting without pulmonary embolism but a swollen leg, ruptured Baker cysts or muscle hematomas should be ruled out before anticoagulation is started. Systemic thrombolysis or surgical thrombectomy is reserved for young patients with acute isolated thromboses. Thrombectomy must also be kept in reserve for the most severe form of deep venous thromboses, the phlegmasia cerulea dolens. In thrombophlebitis, no anticoagulation is indicated except in bedridden patients. The others must remain mobile and may be treated by systemic and local antiinflammatory drugs, incision of thrombosed varices, and bandages.

A prospective study of a series of 77 patients on adjuvant radiochemotherapy following surgery for high-grade gliomas was conducted to evaluate the risk of deep vein thrombosis and identify risk factors. We found a 20.8% risk of deep vein thrombosis at 12 months (standard error = 4.8%) and a 31.7% risk (standard error = 7.4%) at 24 months (Kaplan-Meier method). Twenty patients (26%) developed deep vein thrombosis with a maximum incidence within the first 7 months after surgery when chemotherapy was still being administered, often with corticosteroids. The risk factors identified were histology (glioblastoma versus anaplastic astrocytoma, P = 0.032, log rank test; 0.0485 L-ratio) and the presence of paresis (P = 0.010, log rank test; 0.0161 L-ratio). A borderline tendency was found for an association between the deep vein thrombosis site and the side of paresis (P = 0.103, Fisher's exact test). Four patients (5%) had massive pulmonary embolism, which was fatal in 3 (4%).

A 16 patients with 20 vascular TOS have been evaluated at the our Institute. Fourteen of them were female, and 2 male patients, with average age of 33.1 (18-44) years. 19 of them had congenital, and one acquired TOS after trauma at neck-shoulder region. 13 cases had arterial, and 7 venous TOS. In 10 cases a cause of TOS was cervical rib, in one scar tissue after clavicle fracture, while in 9 soft tissue anomalies. Eight cases with arterial TOS had a hand ischemia, one TIA and 5 periodical symptoms only during the arm hyperabduction. Two cases with venous TOS also had symptoms and signs during arm hyperabducrtion only, while five patients had axillary-subclavian deep venous thrombosis (DVT). All patients underwent CW-Doppler, Duplex-ultrasonographic and angiographic examination in normal position of the arm and during the hyperabduction. The four aneurysms of the subclavian artery, two poststenotic dilatation of the subclavian artery were found as well as one thrombosis of the axillary artery and 8 brachial artery embolism. The operative treatment consists from decompression and vascular procedure. A decompression procedure include 10 resections of the cervical rib, three transaxilary and 6 supraclavcular resection of the first rib, as well as one scalenectomy. A vascular procedures included 8 transbrachial thrombembolectomy and 4 resection and replacement of subclavian artery aneurysms. Four early complications were noticed: two partial pneumothorax, and two transiet medianus nerve paresis. The follow-up period was between one and six years (mean 3 years). In this period one (12.5%) late arterial occlusion was found. The vascular TOS is more rare than neurogenic, however in mostly cases requires surgical management.

From the information presented in this article, it can be concluded that clinical suspicion of VTE should be increased in patients with a history of VTE, recent surgery, spinal cord injury, trauma, or malignancy. A variety of medical illnesses also increase the risk of venous thrombosis, including congestive heart failure, myocardial infarction, stroke with paresis, nephrotic syndrome, cigarette smoking, and obesity. Hypercoagulable states, such as antithrombin III deficiency, protein C deficiency, protein S deficiency, or factor V Leiden mutation should be considered in those patients who develop VTE in the absence of known risk factors. Additionally, the presence of vena caval filters does not exclude the possibility of PE or recurrent DVT. With a careful assessment of risk, physicians can hope to increase the diagnostic yield of VTE and decrease the significant morbidity and mortality of caused by this disease.
