Bladder distention is an infrequently reported cause of venous obstruction that may be confused clinically with deep venous thrombosis or congestive heart failure. Urinary symptoms may be minimal or absent. Herein we describe a 73-year-old man with unilateral lower extremity edema caused by a distended urinary bladder. In addition, we review the clinical manifestations of 15 previously reported cases of venous obstruction due to urinary retention. Of the 15 patients, all but 1 had painless bilateral lower extremity edema. In most cases, the cause of bladder distention was benign prostatic enlargement.

The clinical efficacy of thromboprophylaxis with aspirin and dextran 40 was compared in a prospective review of 530 geriatric hip fracture patients treated surgically. All patients were also treated with early mobilization with weight bearing as tolerated and above-knee elastic stockings. In addition to clinical efficacy in preventing thromboembolic complications [deep vein thrombosis (DVT), pulmonary embolism (PE)], safety and cost-effectiveness were also assessed. The overall incidence of clinical thromboembolic disease was 2.8% (DVT = 0.4%, PE = 2.4%). The incidence of DVT (0.5%) and PE (2.6%) in the aspirin group was essentially the same as the incidence of DVT (0.3%) and PE (2.4%) in the dextran group. The inhospital mortality rate (aspirin 4.6%, dextran 3.8%), wound drainage (aspirin 1.5%, dextran 0.9%), deep wound infection (aspirin 0.5%, dextran 0.3%), gastrointestinal bleeding (aspirin 2.1%, dextran 1.5%), and congestive heart failure (aspirin 2.6%, dextran 1.8%) did not differ significantly between the two groups. The intraoperative transfusion rate was similar in both groups (aspirin .65 units, dextran .55 units). However, postoperatively, the transfusion rate was significantly higher in the dextran group (aspirin .26 units, dextran .41 units, p < .05). The treatment of thromboembolic complications was the same for each group and therefore represents similar treatment costs. However, the cost of prophylaxis with dextran was $309 per patient and with aspirin was $1.79 per patient. Our findings suggest that, based on clinical diagnostic criteria, aspirin and dextran are equally effective thromboembolic prophylactic agents in geriatric hip fracture patients. The safety, cost, and ease of administration of aspirin may make its use more desirable.

Despite being the most common benign intracardiac tumour with an excellent prognosis after surgical excision the incidence of atrial myxoma (except at autopsy) is unknown. We reviewed all patients admitted to the National Cardiac Surgery Unit (n = 26) with an atrial myxoma over a fifteen year period (1977-1991) to compile national incidence data and assess pre-operative diagnosis, management, surgical technique, and outcome. Preoperative symptoms were: congestive cardiac failure (12 patients), embolism (8 patients), constitutional (3 patients), asymptomatic (2 patients) and tachyarrhythmia (1 patient). The diagnosis was confirmed by 2D echocardiography alone in thirteen patients and by a combination of echocardiography and angiography in thirteen patients. At operation the site of the tumour was left atrial in 24 patients and bi-atrial in two patients. All cases were confirmed by histology. All patients made a good post-operative recovery, although one patient survived a pulmonary embolus and one patient developed a deep venous thrombosis. There has been one late death (five months after surgery) from a cerebrovascular accident. Serial echocardiography has revealed one recurrence to date (8 years after surgery). The surgical incidence of these tumours in the Republic of Ireland over the study period was 0.5 atrial myxomas/million population/year. Although rare atrial myxomas are the most important cardiac tumours to diagnose as the results from surgery are excellent.

In 53 patients with recent (< 6 hrs) acute myocardial infarction a study was undertaken to evaluate the safety of conjunctive therapy with streptokinase (1.5 mln U), aspirin (150 mg) and low molecular weight heparin (Fraxiparine). Patients were treated with Fraxiparine 250 U anti-Xa IC/kg/24 hrs iv for 2 days (with bolus 12.5 U anti-Xa IC/kg), and 125 U anti-Xa IC/kg twice a day sc for 5 subsequent days. Clinical course in one-year observation was compared regarding the time the therapy was initiated. In the group undergoing therapy 3-6 hrs after the infarct had occurred 4 (7.5%) patients died (2 during hospitalization, 2 after discharge). In 31 patients treated within 3 hrs of the myocardial infarction there were fewer cases of recurrent myocardial infarction, unstable angina or congestive heart failure necessitating rehospitalization their (9.1%) than in 22 patients included in the treatment regimen between 3 rd and 6th h of the infarction (27.3%). Earlier thrombolysis was also connected with higher left ventricular ejection fraction (55 +/- 8% vs 49 +/- 10%) and more frequent peak CK-MB values 12 hrs after thrombolysis (81% and 68% of patients respectively). Neither symptomatic deep vein thrombosis nor pulmonary embolism was detected. The left ventricular thrombosis was diagnosed by echocardiography in 4 of 20 patients (20%) with the first anterior myocardial infarction. There was neither bleeding requiring blood transfusion nor cerebrovascular stroke. The treatment with Fraxiparine did not induce the prolongation of APTT values. Conjunctive thrombolytic therapy with low molecular weight heparin was safe and followed by a favorable outcome of the acute myocardial infarction, especially if instituted within the first 3 hrs after the onset of infarction.

Intravenous immune globulin (IVIg) is advocated as a safe treatment for immune-mediated neurologic disease. We reviewed the medical records of 88 patients who were given IVIg for a neurologic illness. Major complications in four patients (4.5%) included congestive heart failure in a patient with polymyositis, hypotension after a recent myocardial infarction, deep venous thrombosis in a bed-bound patient, and acute renal failure with diabetic nephropathy. Other adverse effects included vasomotor symptoms 26, headache 23, rash 5, leukopenia 4, fever 3, neutropenia 1, proteinuria (1.9 g/day) 1, viral syndrome 1, dyspnea 1, and pruritus 1. Fifty-two patients (59%) had some adverse effect of IVIg infusion, most commonly vasomotor symptoms, headaches, fever, or shortness of breath in 40 (45%), which improved with reduced infusion rate or symptomatic medications. Five (6%) had asymptomatic laboratory abnormalities and seven (8%) had other minor adverse effects. Adverse effects led to discontinuation of therapy in 16% and permanent termination of therapy in 10% of patients. There was no mortality or long-term morbidity. Although adverse effects were frequent, serious complications were rare except in patients with heart disease, renal insufficiency, and bed-bound state.

This study was conducted to identify patients at high risk of the development of Pulmonary Embolism (PE) after open heart surgery, to evaluate pertinent diagnostic methods, and to assess the mortality associated with this complication. We evaluated the records of 2,551 consecutive patients who underwent open heart surgery over a 10-year period to identify those patients in whom PE developed. All surgical reports, ventilation/perfusion scans, pulmonary angiograms, and autopsies from the same period were also reviewed. Preoperative and postoperative risk factors for pulmonary embolism were also analyzed, as well as the outcome of this complication in each type of surgical procedure. Pulmonary embolism was identified in 69 (2.7%) patients after open heart surgery, in 43 (62.3%) of whom the diagnosis was established within the first week of surgery. Factors associated with high incidence for PE were hyperlipidemia, congestive heart failure and heparin-induced thrombocytopenia (P < 0.001); obesity and prolonged mechanical ventilation (P < 0.005); and prior right heart catheterization by the femoral approach and prior PE and/or deep vein thrombosis (P < 0.05). The diagnosis of PE was established by a high-probability ventilation/perfusion scan in 25 patients, by pulmonary angiography in 42 (29 of whom had prior V/Q scan read as intermediate or low probability for PE) and by autopsy in two patients. The mortality rate in patients who had PE was 7.2%, while in those without this complication it was 3.2%. These findings suggest that aggressive approach for the diagnosis of PE by pulmonary angiography whenever the V/Q scan is not read as high probability is crucial in patients with recent open heart surgery; such approach may identify patients with PE at an early stage and may have an impact in reducing mortality incurred by this complication. This diagnostic assessment should be emphasized in the perioperative period, especially in patients with multiple significant and identifiable risk factors for PE.

Arteriovenous fistula (AVF) is a rare, late complication of lumbar disc surgery. It is often not suspected and the symptoms are diagnosed as heart failure or deep venous thrombosis. We report a case in which the patient developed leg swelling and high-output congestive heart failure due to a left ilioiliac AVF after lumbar laminectomy.

The frequency of clinical recurrence and pulmonary embolism in patients with acute deep venous thrombosis is reduced to the same extent by hospital treatment (with unfractionated heparin) as by treatment at home (with low-molecular-weight heparin). Very few data on subjective parameters of effectiveness have been published. We performed a prospective randomized trial comparing outpatient with in-hospital treatment in 28 patients. Six clinical and quality-of-life related parameters of effectiveness were assessed quantitatively: clinical course (with a score system), pain of venous congestion of the calf muscles (with Lowenberg's test), subjective perception of pain and general well-being (with visual analogue scales), satisfaction with the care provided, and absence from work. Subjective effectiveness was compared with the costs of each form of treatment. Outpatient treatment was significantly more effective than in-hospital treatment with regard to the objective parameters. It was, however, associated with less well-being and more pain than in-hospital treatment. The discrepancy is explained by eventually insufficient adjuvant treatment measures (which consisted of external leg compression by stockings and forced walking) and by anxiety brought on by the information that potentially lethal pulmonary embolism could occur despite anticoagulant therapy. Outpatient treatment was less costly. On the average and per patient it was CHF 3944 less expensive than treatment in hospital. An estimation reveals that the Swiss health care system would save about CHF 25 million per year if the 85% of patients with deep-vein thrombosis suitable for home care were given this form of treatment. We conclude that outpatient management is subjectively cost-effective but should be optimised to eliminate certain drawbacks associated with it.

Recurrent venous thrombotic and thromboembolic disease, once thought to be an uncommon entity, is increasingly being recognized. Etiologies of recurrent deep venous thrombosis usually include elements of Virchow's triad. Venous stasis (e.g., immobilization, congestive heart failure, acute myocardial infarction, obesity), hypercoagulability (e.g., malignancy, inflammatory bowel disease, hyperhomocysteinemia, protein C resistance, antithrombin III, protein C or S deficiency) and endothelial trauma (e.g., surgical trauma, venous trauma, in-dwelling venous instrumentation) are risk factors. Diagnosis is dependent on objective testing, including venography duplex Doppler (color) ultrasonography and impedance plethysmography. Treatment is usually started with heparin or low-molecular-weight heparin and advanced to warfarin (adjusted to international normalized ratio). Prophylaxis may continue using low-molecular-weight heparin, warfarin, venacaval interruption (Greenfield filter), or concomitant use of the platelet-active agent indobufen and graduated compression stockings.

Venous ulcers, a chronic disabling condition, present a complex management challenge to the interdisciplinary team in the community setting. The incidence of venous ulcers is increasing as the population ages with such comorbidities as congestive heart failure (CHF), deep vein thrombosis (DVT), obesity, and others. Disability associated with venous ulcers may increase caregiver burden in accomplishing the patient's activities of daily living (ADL), and handicap may exist from difficulty in community participation because of impaired mobility. Venous hypertension, the primary culprit in venous ulcerations, must be managed with an arsenal of strategies to control the underlying condition, heal the wound, and prevent recurrence.
