Vascular complications such as pseudoaneurysm, arterial thrombosis, luminal stenosis due to extrinsic compression, deep venous thrombosis, and arteriovenous fistula are known complications of osteochondroma. The authors describe three cases of vascular injury caused by osteochondroma: popliteal artery impingement, popliteal artery pseudoaneurysm formation, and superficial femoral artery pseudoaneurysm with peripheral occlusion of the tibial and peroneal arteries due to embolization. Fifty-six cases of vascular complications due to osteochondroma from the English literature are also reviewed. This entity should be considered in young patients with evidence of peripheral vascular insufficiency or in patients with known osteochondroma who develop symptoms of local pain and swelling in the involved extremity.

The authors discuss the results of 81 total knee arthroplasties in 65 patients performed between April 1987 and April 1989 using a Tricon hybrid system, consisting of the Tricon M bio-ingrowth femoral prosthesis and the Tricon C cemented tibial component. The Tricon metal-backed patella was used until February 29, 1988, when the all-plastic Tricon C patella was introduced. With an average follow up of 24 months (range: 12 to 48), 38 arthroplasties using this hybrid system were rated as excellent (47%) and 38 were rated as good (47%). The Hospital for Special Surgery scores, which averaged 53 preoperatively, averaged 80 at the most recent follow-up assessment. At the most recent follow-up assessment, 79% of osteoarthritis patients and 56% of rheumatoid arthritis patients have no pain at rest, while 19% of osteoarthritis patients and 44% of rheumatoid arthritis patients have mild pain at rest. Sixty-four percent of osteoarthritis patients and 33% of rheumatoid arthritis patients have no pain while walking, whereas 26% of osteoarthritis patients and 56% of rheumatoid arthritis patients have mild pain while walking. Postoperative complications included fragmentation of the patella in five patients, all occurring with the metal-backed patella. Five patients also experienced petellar subluxation (two metal-backed and three all-polyethylene). One patient had deep venous thrombosis which was treated successfully by re-hospitalization and heparin therapy; one patient with chronic heart disease expired 4 days postoperatively. Use of the Tricon hybrid system has resulted in 94% of all patients having a good or excellent result an average of 24 months postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)

A 70-year-old woman on maintenance hemodialysis for 3 years was admitted to our hospital because of deep vein thrombosis (DVT) in the right femoral vein. Seven days before admission, she suddenly noticed severe pain in her right inguinal region while she was walking on the street. A wide range of stenosis from the iliac to the distal femoral region was detected by both CT scanning and venography. Her hematocrit reading was 30% and her serum erythropoietin level was 10.5 MU/ml, which was within the normal range, on the day of admission. The results of routine coagulation tests, including prothrombin time, activated partial thrombin time and plasma fibrinogen values, were normal. Plasma anti-thrombin III and plasminogen were also normal. In contrast, beta-thromboglobulin, platelet factor IV, fibrinogen degradation product, D-dimer, thrombin-antithrombin III complex (TAT) and fibrinopeptide A were abnormally elevated. In the venous occlusion test which was performed in the forearm of the opposite side of the arterio-venous shunt, plasma tissue type plas-minogen activator values showed little response to occlusion indicating that the vessel endothelium may have been partially damaged. These data suggest that the DVT had been induced by imbalance of increased blood coagulation and decreased fibrinolytic activity. Damaged vascular wall may also have contributed to the production of DVT. Furthermore, it is surprising that the patient had elevated values of D-dimer and TAT for many years without recurrence of the DVT. Spontaneous DVT in an apparently healthy individual on maintenance hemodialysis seems to be rare, compared with arterial thrombosis.(ABSTRACT TRUNCATED AT 250 WORDS)

Fibrinolysis of 19 patients who developed CVI after deep vein thrombosis was examined. Mean age of patients at the first thrombosis was 31.8 years. For testing fibrinolysis fibrinogen, plasminogen, AP, ECLT, with venous occlusion were determined. In 10 patients t-PA and PAI-1 activities were also measured and plethysmography was carried out. For screening blood coagulation abnormalities of TCT count, PT, APTT, TT, AT III, protein C were tested. The common abnormality was the decreased fibrinolysis. Patients had been on coumarin for 6.14 years before entering the study. Under coumarin treatment 6 patients had relapsed DVT, 4 had crural ulcer and CVI deteriorated in 8 patients. Therefore we added fibrinolysis increasing PPS to coumarin. PPS dose was individually determined by PPS loading test (150-500 mg). Mean observation time with the combined treatment was 2.92 years. Clinical check up and fibrinolysis test were carried out every 6 months. Clinical improvement occurred in 13 patients, (decrease of swelling, pain etc). Two out of 4 patients with stasis ulcer experienced complete healing; in 1 the ulcer territory diminished in size. Maximum venous outflow improved in 7 patients, 3 patients were non-responders. We observed an increase of fibrinolysis in 10 patients. Venous occlusion enhanced the fibrinolysis increasing effect of PPS. The activity reached its maximum by the first control. The fibrinolysis increase and the clinical improvement do not always run parallel, therefore other effects of PPS as the reason for being beneficial in CVI must be considered (antiinflammatory, ect.). Combination of coumarin and PPS seems to be an effective therapy in CVI with decreased fibrinolysis.

Subcutaneous heparin injections are frequently prescribed for the prevention of deep vein thrombosis. One of the most commonly encountered adverse physiological responses to this intervention is the formation of a haematoma at the injection site. This creates a challenge for the nurse attempting to minimize haematoma formation and/or patient discomfort during the treatment regime. The purpose of this study was to determine if the application of ice to subcutaneous heparin injection sites decreases the incidence and size of haematoma formation and/or minimizes patient discomfort. The study used a quasi-experimental design with the subjects as their own control. A convenience sample of 70 subjects was each given two injections of subcutaneous heparin, 12 hours apart. Ice was applied pre- and post-injection to one of the sites. Immediately following each injection, the subjects were asked to rate the level of perceived discomfort at the time of the injection using a visual analogue scale. Forty-eight hours post-injection, the nurse inspected the injection sites for the presence of haematoma. Results showed that when ice was applied there was no significant difference in the incidence or size of haematoma; however, the subject's perception of pain was significantly less.

Gradual distraction with the Ilizarov external fixator was used on 26 patients for short stature. 19 patients complete their program (G1, 64 fixators): average pain is 12 cm for an initial stature of 133 cm; 3 patients stopped their program before end for psychological problems. Surgical procedures included: section of tensor fascia lata (9 cases), lengthening of Achilleus tendon (16 cases), skin debridement around pins (3 cases), modification of apparatus under general anesthesia (53 cases), iterative corticotomy (4 cases in G1) or peroneus section (4 in G1). Healing index was 23 D/cm for femur and 29 D/cm for tibia. Events occurred during the program: 1) mechanicals: 1 pin rupture; 2) bony: 1 delayed healing needing graftng, 3 bone impactions and 11 fractures after fixator removal, 1 axial deviation needing callotasy at fixator removal; 3) nervous and musculary: 12 transitory peroneal nerve lesions, 3 compartment syndromes, 2 proximal sciatic lesion, recovered, and 2 motor palsies; 4) joint lesions: 1 knee stiffness needing an extensive quadriceps release; 5) vascular: 1 deep venous thrombosis; 6) infectious: 10 superficial infections around pins, 4 osteitis and 1 arthritis; 7) cutaneous: 7 scar removals. Lengthening of people with short stature concerns motivated people fully aware of events occurring during a lengthening program which will decrease the initial handicap.

Pseudothrombophlebitis syndrome is the occurrence of calf pain and swelling caused by extrinsic compression of the popliteal vessels by an enlarging Baker's cyst or by calf inflammation that occurs as the result of a ruptured Baker's cyst. Few cases of pseudothrombophlebitis syndrome have been reported in patients less than 18 years of age, and nearly all these young patients had juvenile rheumatoid arthritis. Reported here is the case of a 17-year-old male patient without rheumatic disease who presented to the outpatient clinic with a 1-week history of an increasingly painful swelling of the right calf without any history of precipitating factors for a deep vein thrombosis.

The aim of this study was to investigate the effects of recombinant human erythropoietin (rh-EPO) in patients with cancer-related anaemia. Thirty-six ambulatory patients who had malignant neoplasms and haemoglobin (Hb) values of < 11 g/dl (Pretoria is 1,310 m above sea level) entered the study. Patients with renal insufficiency or anaemia caused by bleeding or haemolysis, and patients with iron deficiency or megaloblastic anaemia, were not entered in the study. 22 IU/kg rh-EPO was given subcutaneously 3 times/week. The dose was escalated if Hb values did not rise after 4 weeks. All 36 patients were evaluable for toxicity. Side effects ascribed to rh-EPO were pain or discomfort at the site of injection (12 patients), heart palpitations (3 patients), skin rash (2 patients) and hypertension, deep vein thrombosis, and myalgia in 1 patient each. Thirty of the 36 patients who entered the study were evaluable for response. There were 16 females and 14 males among the evaluable patients. Median age was 64.5 years. Response, defined as an increase of Hb of at least 2 g/dl or to 12.5 g/dl, for at least 1 month, was documented in 12 patients. This was accompanied by an improvement in performance status and occurred within 1 month in 5 of the 12 patients who responded. rh-EPO has a limited but measurable therapeutic value for patients with cancer-associated anaemia.

Laparoscopic repair of 200 inguinal hernias by the preperitoneal approach is described. The technique uses a large mesh either of polypropylene or of ePTFE-Goretex. The average duration of the procedure was 45 minutes for unilateral hernias and 71 minutes for bilateral hernias. Postoperative pain was minimal and complications rare (no infection, one deep vein thrombosis). The mean duration of hospital stay was 44 hours. At a maximum follow-up of 22 months only one hernia has recurred. This technique of hernia repair has the advantage of minimal postoperative pain and early return to work with minimal recurrence of the hernia.

In a review of 52 cases of deep venous thrombosis (DVT) of the upper extremity, the predisposing factors, clinical manifestations, topography of thrombosis, treatment employed, presence of complications, and evolution of the disease were investigated. In all patients, clinical manifestations were confirmed by bilateral phlebography and superior cavography. Thirty-five (67%) of the patients were male; the mean age was 45.4 years. Clinical manifestations were edema in 51 patients (98%), dilated collateral circulation in 37 (71%), and pain in 33 (63%). One patient presented with pulmonary embolism and another with phlegmasia cerulea dolens-like signs in an extremity. The right axillosubclavian segment was involved in 23 patients (44%), the left in 17 (33%), and both left and right segments associated with DVT of the superior vena cava in 11 (21%). One patient had left and right axillosubclavian thrombosis without superior vena cava involvement. The main predisposing factors identified were central venous catheterization in 15 patients (29%) and extrinsic compression, caused mainly by cancer, in 15 (29%). There were three cases of DVT related to effort and three to thoracic outlet syndrome. The majority of patients were treated with systemic heparin therapy followed by oral anticoagulation. During a follow-up of 6 months, nine patients died, one from pulmonary embolism; 21 patients (40%) were symptom-free, 11 (21%) had minimal edema, and seven (13%) had symptomless edema. Four patients (8%) were lost to follow-up. The overall incidence of pulmonary embolism was 4%.(ABSTRACT TRUNCATED AT 250 WORDS)
