Crack Cocaine Mimicking Pulmonary Embolism on Pulmonary Ventilation/Perfusion Lung Scan A Case Report

SummaryTo avoid angiography in patients with clinically suspected pulmonary embolism and non-diagnostic lung scan results, the use of D-dimer has been advocated. We assessed plasma samples of 151 consecutive patients with clinically suspected pulmonary embolism. Lung scan results were: normal (43), high probability (48) and non-diagnostic (60; angiography performed in 43; 12 pulmonary emboli). Reproducibility, cut-off values, specificity, and percentage of patients in whom angiography could be avoided (with sensitivity 100%) were determined for two latex and four ELISA assays.The latex methods (cut-off 500 μg/1) agreed with corresponding ELISA tests in 83% (15% normal latex, abnormal ELISA) and 81% (7% normal latex, abnormal ELISA). ELISA methods showed considerable within- (2–17%) and between-assay Variation (12–26%). Cut-off values were 25 μg/l (Behring), 50 μg/l (Agen), 300 μg/l (Stago) and 550 μg/l (Organon). Specificity was 14–38%; in 4–15% of patients angiography could be avoided.We conclude that latex D-dimer assays appear not useful, whereas ELISA methods may be of limited value in the exclusion of pulmonary embolism.

Ovarian Vein Thrombosis

Ovarian vein thrombosis (OVT) is a rare medical disorder, which is most often found in the immediate postpartum period. OVT is rarely considered idiopathic. We report a case of idiopathic OVT with pulmonary embolism in a 33-year-old woman who presented with abdominal pain. Computed tomography and postoperative pathology confirmed the diagnosis of idiopathic OVT. To date, only 12 cases of idiopathic OVT have been reported. In this case report, we present a summary of these cases and a review of literature regarding management of idiopathic OVT.

Lung Scan

100 post-operative subjects were observed following total hip replacement using 125I-fibrinogen (125I-Fg) and impedance plethysmography (IPG) with thigh cuff. Phlebo-grams were obtained if these tests indicated venous thrombosis. Also, lung scan was obtained if clinical evidence of pulmonary embolism developed. Sustained significant isotope localization occurred in 40. 32 of these had abnormal IPG. Four patients had minor pulmonary embolism, which was associated with abnormality of either 125I-Fg or IPG. All major obstructive venous thrombosis and all moderately extensive thrombosis was associated with abnormal IPG. Only minute thrombi were not correctly classified by IPG. The following conclusions are supported by this experience. 1) If prospectively applied in patients at risk, the combination of both techniques (125I-Fg, IPG) is capable of detecting all silent venous thrombosis even minute thrombi of negligible significance. 2) IPG is capable of detecting all major obstructive and all moderately extensive thrombi, that is, all thrombosis of clinical significance arising in the leg. 3) Minute thrombi will not be detected by IPG alone and small emboli resulting from detachment of such minute thrombi would be unheralded unless monitoring includes 125I-Fg.
