An 81 year old male patient treated by sulfonylurea and diet was known to have type II diabetes for three years. Because of pulmonary embolism phenprocoumon had been administered for four months. Painful livedo racemosa developed acutely on both lateral sides of the feet and the left knee. A necrosis of the skin over the base of the left small toe developed within a few days. On the basis of the clinical picture cholesterol-embolism was diagnosed. Since anticoagulation is known to promote cholesterol-embolism it was discontinued. Prostaglandin E1 infusions into both legs were administered. Within 3 months the cutaneous lesions healed completely.

Late pericarditis following myocardial infarction, cardiac surgery, or trauma is referred to as postmyocardial infarction syndrome (PMIS) or postcardiotomy syndrome (PCS), respectively. The term postcardiac injury syndrome (PCIS) is used to encompass both these entities. PCIS is characterized by fever, pleuropericardial pain, pericarditis, and pulmonary involvement. Abnormal laboratory findings include leukocytosis, high sedimentation rate, and chest x-ray abnormalities of pleural effusion with or without pulmonary infiltrates. Evidence supports an immunopathic etiology; viruses may play a contributing role. The course is benign but rare complications include tamponade, constriction, anemia, and coronary bypass graft occlusion. Anti-inflammatory agents are helpful; indo-methacin and steroids are preferably avoided. Rarely, PMIS-like syndrome may occur following pulmonary embolism. Anticoagulation and steroids have been used successfully in the latter situation.

Twenty-five consecutive adult women with nonparalytic spinal deformity were treated with fusion to the sacrum. Two patients were lost to follow-up and one patient died, leaving 22 patients for review. All patients underwent a first-stage anterior spinal fusion without instrumentation followed by a second-stage posterior spinal fusion with Luque-Galveston instrumentation. The average age of the patients was 47 years (range, 25-64 years). The average follow-up was 39 months (range, 24-60 months). Ten patients had had previous surgery in the area of the instrumentation. The main indications were pain (22 patients), loss of sagittal plane balance (17 patients), and progression of the deformity (13 patients). Additional procedures included anterior corpectomies (five patients), anterior and posterior osteotomies (two patients), posterior osteotomies (eight patients), and posterior decompression (five patients). The average curve correction was 27% for thoracic scoliosis and 44% for lumbar scoliosis. Physiologic sagittal plane realignment was obtained in four patients who presented preoperatively with sagittal plane deformities. Pain improvement was reported in 14 of 22 (63%) patients. Nineteen (82%) patients had 34 complications. Pseudarthrosis occurred in nine patients (41%) and was successfully repaired in four; hence the fusion rate was 77% at follow-up. Of the 23 patients, one died from pulmonary embolism, 15 (66%) were in good condition, one (4%) was in fair condition, and seven (30%) were in poor condition. Previous surgery and additional procedures such as vertebrectomies or osteotomies did not adversely affect the outcome. There were no permanent neurologic deficits related to the instrumentation or the passage of sublaminar wires. The Luque-Galveston method provided correction of sagittal plane deformities and flatback syndrome.

Six patients suffering from solitary cryofibrinogenaemia are described. In one patient idiopathic cryofibrinogenaemia was present, while the others showed secondary cryofibrinogenaemia associated with borrelia infection, chronic venous insufficiency with pulmonary embolism, primary biliary cirrhosis, diabetes mellitus or von-Willebrand syndrome. Subcutaneous injections of the thrombin-like snake poison batroxobin/ancrod were administered over a period of several weeks. Five patients experienced almost complete remission of their symptoms, especially of pain following cold exposure. In one patient partial relief was achieved. Overall we found a 75% reduction of symptoms. When blood fibrinogen levels are carefully monitored this therapy is an efficient and safe form of treatment for cryofibrinogenaemia.

A follow-up study is reported on 49 patients with acute deep vein thrombosis (DVT) treated on an ambulatory basis. Venography had shown crural DVT in 27 % and proximal extension in 73 %. The initial treatment consisted of heparin (7,500 U iv, 40,000 U sc), ethylbiscoumacetate (900 mg), phenprocoumon (9 mg), and a ready made compression stocking for the calf. The patients were advised to undertake frequent strolls, the first when leaving the office. Pain, swelling and incapacity for walking vanished within two days. The partial thromboplastintime was prolonged 2.4-times on the first day and the thromboplastintime was in the therapeutic range on the second day already. Until follow-up 4 patients died of other diseases. There was no clinical pulmonary embolism, no secondary hospitalisation and only one new DVT. Of 844 months of patients at risk of recurrence 50 % passed under anticoagulants and 70 % with compression therapy. At an average of 19 months, 82 % of patients were asymptomatic and 45 % showed mild chronic venous insufficiency. In contrast, impaired drainage function (by lightreflectionrheography) was found in 79 % overall and in 100 % after DVT of the proximal veins. The discrepancy is explained by the compliance with compression therapy.

A 59 year old patient with leg pain and dyspnea was hospitalized for suspected deep venous thrombosis and pulmonary embolism. The clinical, scintigraphic and radiological findings confirmed the diagnosis. Immediate therapy with heparin and oral warfarin resulted in an improvement of pain and dyspnea within a few days. The strategy for diagnostic evaluation of patients with suspected pulmonary thromboembolism is discussed.

One hundred forty-nine consecutive patients requiring lower extremity total joint arthroplasty were randomized to either coumadin (52 patients) or intermittent pneumatic compression (48 patients) as prophylaxis against deep vein thrombosis (DVT). Forty-nine patients were excluded. When fully ambulatory, the presence or absence of DVT was diagnosed by ascending venography (90% of patients), nuclear venography, venous dopplers, or impedence plethysmography. The two groups were similar in average age (64 years), indication for arthroplasty (pain because of arthritis in 90%), gender (98% male), and average number of risk factors (2.4). Twenty-five percent of patients on coumadin and 25% of patients on intermittent pneumatic compression (IPC) developed DVT. IPC was more effective than coumadin following primary total hip arthroplasties (THAs) (16% versus 24% incidence DVT); coumadin was more effective than IPC following primary total knee arthroplasties (TKAs) (19% versus 32% incidence of DVT). DVT developed in 36% of patients following revision arthroplasty. Seventy-five percent of all thrombi were proximal. Both IPC and coumadin were found to be safe; there was no increased perioperative bleeding in the coumadin group. Of three postoperative deaths, one was possibly due to pulmonary embolism (PE).

The history, physical examination, chest radiograph, electrocardiogram and blood gases were evaluated in patients with suspected acute pulmonary embolism (PE) and no history or evidence of pre-existing cardiac or pulmonary disease. The investigation focused upon patients with no previous cardiac or pulmonary disease in order to evaluate the clinical characteristics that were due only to PE. Acute PE was present in 117 patients and PE was excluded in 248 patients. Among the patients with PE, dyspnea or tachypnea (greater than or equal to 20/min) was present in 105 of 117 (90 percent). Dyspnea, hemoptysis, or pleuritic pain was present in 107 of 117 (91 percent). The partial pressure of oxygen in arterial blood on room air was less than 80 mm Hg in 65 of 88 (74 percent). The alveolar-arterial oxygen gradient was greater than 20 mm Hg in 76 of 88 (86 percent). The chest radiograph was abnormal in 98 of 117 (84 percent). Atelectasis and/or pulmonary parenchymal abnormalities were most common, 79 of 117 (68 percent). Nonspecific ST segment or T wave change was the most common electrocardiographic abnormality, in 44 of 89 (49 percent). Dyspnea, tachypnea, or signs of deep venous thrombosis was present in 107 of 117 (91 percent). Dyspnea or tachypnea or pleuritic pain was present in 113 of 117 (97 percent). Dyspnea or tachypnea or pleuritic pain was present in 113 of 117 (97 percent). Dyspnea or tachypnea or pleuritic pain or atelectasis or a parenchymal abnormality on the chest radiograph was present in 115 of 117 (98 percent). In conclusion, among the patients with pulmonary embolism that were identified, only a small percentage did not have these important manifestations or combinations of manifestations. Clinical evaluation, though nonspecific, is of considerable value in the selection of patients in whom there is a need for further diagnostic studies.

The diagnostic features of acute pulmonary embolism among 72 patients greater than or equal to 70 years old were evaluated and compared with characteristics of pulmonary embolism among 144 patients 40 to 69 years and 44 patients less than 40 years old. Syndromes characterized by either 1) pleuritic pain or hemoptysis, 2) isolated dyspnea, or 3) circulatory collapse were observed with comparable frequency among patients greater than or equal to 70 years old and younger patients. One of these presenting syndromes occurred in 64 (89%) of the 72 patients greater than or equal to 70 years old. Those who did not show these syndromes were identified on the basis of unexpected radiographic abnormalities, which may have been accompanied by tachypnea or a history of thrombophlebitis. Among the 72 patients greater than or equal to 70 years with pulmonary embolism, dyspnea or tachypnea (respirations greater than or equal to 20/min) occurred in 66 (92%), dyspnea or tachypnea or pleuritic pain in 68 (94%) and dyspnea or tachypnea or radiographic evidence of atelectasis or a parenchymal abnormality in 72 (100%). Complications of angiography were evaluated among patients with and without pulmonary embolism. Major complications of pulmonary angiography among patients greater than or equal to 70 years old (2 [1%] of 200) were not more frequent than among younger patients (6 [1.1%] of 562) (p = NS). However, renal failure (major or minor) was more frequent in patients greater than or equal to 70 years old than in younger patients (6 [3%] of 200 versus 4 [0.7%] of 562) (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Although there is a critical need for effective contraception in the immediate postpartum period for women who are not breastfeeding, this need must be balanced against the inherent risks. The most effective form of contraceptive protection--oral contraceptives (OCs)--can present an increased risk of thromboembolism in the period after delivery. The thrombotic changes associated with pregnancy, and the statistics and vascular damage following a delivery, can combine to create greater potential for thromboembolism after delivery than during pregnancy. Reported here is the case of a 21-year-old woman who, 4 weeks postpartum, developed pain and swelling in the right lower calf and mottled discoloration extending from the proximal thigh to the toes. A diagnosis of deep venous thrombosis was made and heparin was administered. In the hospital, the patient experienced pleuritic chest pain and diaphoresis. A ventilation-perfusion scan indicated a pulmonary embolism. 1 week after delivery, the patient had initiated use of Triphasil. Although this woman had other risk factors (obesity, light cigarette smoking, and a sedentary life-style), OC use in the immediate postpartum period may have been the final factor precipitating the thromboembolic event. It is recommended that OC use should be delayed until at least 2 weeks postpartum in women without other risk factors for thromboembolism and until 4-6 weeks postpartum in those with such factors.
