Deep vein thrombosis, pulmonary embolism, and pulmonary thrombosis in situ are rare in childhood and adolescence [1,2]. Unfortunately, these diagnoses may be unsuspected in a pediatric patient with dyspnea and chest pain. This article illustrates the diagnostic and therapeutic challenges that arose from unrecognized chronic thrombotic disease in an adolescent.

A patient with Parkinson's disease was admitted because of recurrent chest pain and dyspnea. Based on high clinical suspicion and a high-probability lung scan, the diagnosis of pulmonary embolism was made. Anticoagulation therapy was administered and the patient remained free of symptoms during the follow-up period of two years. Pulmonary embolism is reported as a possible adverse reaction to levodopa therapy and a frequent, but under-recognized cause of death in patients with parkinsonism. Clinicians should think of pulmonary embolism, a common yet difficult diagnosis, when a parkinsonian patient presents with chest pain and dyspnea.

We describe a case of progressive deep venous thrombosis and chest pain studied by contrast-enhanced magnetic resonance (MR) angiography with the new intravascular contrast medium CLARISCAN (NC100150 Injection). Combined MR venography and angiography demonstrated pelvic vein thrombosis and consecutive pulmonary embolism caused by a large abdominal tumor, diagnosed as an ovarian cancer after surgery. The potential role of an intravascular contrast medium for studying the vascular system in multiple regions of the body within a single examination without the need for bolus timing is discussed. J. Magn. Reson. Imaging 2000;12:497-500.

It is nearly impossible to follow and integrate all the new information in each subspeciality of cardiology. In the last months, important data has been published which may change clinical practice. In this domain, over half the cases of suspected coronary chest pain would only require a very short stay in a chest pain unit. The history, an accurate evaluation of symptoms, the application of Bayesian analysis, ECG interpretation and serum troponine measurement, associated with a degree of clinical experience, will allow orientation of the patient to a coronary care unit or hospital discharge (with possible out-patient referral). Patients with true unstable angina will no longer be treated by continuous intravenous injection of non-fractionated heparin because, in theory and in practice, this has been replaced with subcutaneous LMW heparin.... On the other hand, the electric syringe will continue to be required for the integration of the anti-GPIIB-IIIA for the treatment of unstable angina after the recommendations published concomitantly in the United States and Europe. This type of patient, especially with a "positive" troponine, will probably not be kept waiting long before referral to the catheter laboratory for coronary angiography and revascularisation. The long-term results of the FRISC II trial are confirmed by an even earlier invasive approach (Tactics-Timi 18) using anti-GPIIb-IIIa. In the first hours, and independently of other older prognostic factors, it will be possible to "predict or compare" the risk of coronary recurrence based on the results of certain biological "markers". In many centres, cases with ST elevation on the ECG could well be included in a phase III "medical protocol", associating a half-dose thrombolytic and an anti-GPIIb-IIIa. Finally, patients who will have been admitted to the chest pain unit with a suspected pulmonary embolism, for example because they had not been treated prophylactically with aspirin before hip surgery, will probably have the choice, after d-dimer measurement, between pulmonary scintigraphy and helicoidal CT scan. If the diagnosis of pulmonary embolism is confirmed, a single subcutaneous injection of LMW heparin could replace the conventional continuous intravenous injection of heparin. The earliest possible oral anticancer ... pardon me I anticoagulant treatment should be prescribed and explained.

The first part of this study retrospectively compared the discriminatory power of spiral CT versus clinical findings in 112 consecutive patients referred with chest pain or dyspnoea. Spiral CT exhibited a sensitivity 91.9%; specificity 98.7%; PPV 97.1%; NPV 96.1%; accuracy 96.4%. No other test or clinical parameter had acceptable accuracy. The SimpliRED test is a latex method of estimating the level of D-dimer. The second part of this study determined that, in a similar consecutive series of patients referred for lung scintigrams, although SimpliRED tests had a NPV 95.5%, 59/126 (46.8%) consecutive were positive. However on the basis of clinical effectiveness and cost, imaging for suspected pulmonary embolism should be based on a combination of D-dimer estimation and spiral CT.

A case of 68 years old women suffering from chronic anemia, myelodysplastic syndrome and treated with progestogen due to endometrial hypertrophy is presented. Initially she was admitted to a regional hospital because of progressive weakness and exertional dyspnea. Three months earlier she reported an episode of acute dyspnea and chest pain. On the basis of clinical symptoms and perfusion lung scintigraphy pulmonary embolism (PE) was diagnosed. Patient received i.v. heparin which was changed to s.c. nadroparine subcutaneously. Platelet count dropped to 55,000'/ml on fifth day of treatment from initial level of about 200,000'/ml. Heparin induced thrombocytopenia was diagnosed, heparin was stopped and ticlopidine was recommended. After 3 weeks symptoms suggesting recurrent PE were observed. The patient was transferred to National Tuberculosis and Lung Diseases Research Institute. Recombinant hirudine (Refludan) was administrated (bolus 0.4 mg/kg and initial dose of infusion 0.1 mg/kg/h) overlapping with acenocoumarol from second day. Dose of r-hirudine was adjusted to achieve APTT prolongation 1.5 to 2.5 times of mid-normal range. During treatment with r-hirudine no bleeding and new thromboembolic complications occurred. Platelets count remained within normal range. After 14 days clinical improvement was observed, though symptoms of right ventricular overload and hypoxemia were still present after 6 months of treatment with oral anticoagulants suggesting chronic thromboembolic pulmonary hypertension.

We present the case of a 69-year-old man with a history of hypertension and a recent pelvic fracture who presented with acute chest pain, shortness of breath, and severe hypotension. The history of recent pelvic fracture and the clinical manifestations, including the sudden onset of acute respiratory distress, hypotension, and hypoxemia, indicated pulmonary embolism; however, at surgery the patient was found to have an acute dissection of the ascending aorta with obstruction and thrombosis of the right pulmonary artery. This case emphasizes the need to consider such a diagnosis in patients who have unilateral absence of perfusion to the right lung.

A 32-year-old infertility patient with a previous diagnosis of stage IV endometriosis experienced shortness of breath and chest pain. She was diagnosed with a pulmonary embolism by spiral volumetric computed tomography (SVCT) and anticoagulated during hospitalization, although no history of thrombosis was ever identified. She continued to have intermittent symptoms of chest pain, back pain, and shortness of breath for the next 1.5 months. Repeat SVCT revealed a large, right-sided pleural effusion with associated consolidation but no evidence of pulmonary embolism. To obtain a definitive diagnosis, a thoracoscopic pleural biopsy was performed and showed thoracic endometriosis involving the pleura. The patient desired to retain her fertility and opted for treatment with depot medroxyprogesterone. She has been asymptomatic for 2 years with this treatment. This case illustrates the importance of recognizing thoracic endometriosis syndrome and the difficulty diagnosing this condition considering its nonspecific features.

A 25-year-old woman was admitted to our hospital with chest pain and dyspnea, and was diagnosed as having a right atrial myxoma complicated with pulmonary embolism. An emergency operation was performed with cardiopulmonary bypass. A papillary pedunculated tumor was found having a narrow-based attachment to the free atrial wall. After the tumor was carefully removed together with the atrial wall around the attachment, pulmonary embolectomy was performed. Several fragments of the tumor were removed, and sufficient back-flow from the pulmonary artery was established. The postoperative course was uneventful. However, a non-perfused area was observed in the left lower lung on pulmonary hemodynamic scintigraphy at 3 months after the operation. Long-term observation is required due to the high risk for metastasis and recurrence, and further surgical treatment remains the most appropriate treatment option. A second operation may be needed to prevent progression in complications.
