“…This notion, besides explaining the low diagnostic sensitivity of V/Q scanning and of dead space ventilation technique, is in keeping with the observation from the PIOPED trial that about half of the patients with angiographically proven PE in the lower lung regions had atelectasis and/or parenchymal areas of increased opacity in the corresponding lung zones. 40 Such parenchymal abnormalities are likely to affect not only perfusion, but also ventilation scan images. 30 …”

In this article, we review the evolution of scintigraphy for the diagnosis of acute pulmonary embolism (PE). We begin with perfusion (Q) scintigraphy, review the development of diagnostic systems that combine ventilation (V) scintigraphy and chest radiography with the Q scan, and describe in detail the Prospective Investigative Study of Acute Pulmonary Embolism Diagnosis (PISAPED) criteria for diagnostic categorization of the Q scan read in conjunction with the chest radiograph. Finally, we review the results obtained with the PISAPED criteria in clinical research studies. The PISAPED method for lung scan interpretation provides sensitivity and specificity for diagnosing acute PE that is comparable to V/Q scanning and to computed tomography angiography (CTA), with fewer nondiagnostic results than either V/Q or CTA. The criteria can be used effectively in a diagnostic management approach that incorporates the use of a clinical prediction rule. Clinical outcomes in patients in whom PE is excluded in this way are comparable to outcomes for patients in whom the diagnosis is excluded by CTA or conventional angiography.

“…In the event of embolism, there is dyspnoea, tachypnoea with accompanying decreases in blood PO 2 levels. Most patients (88%) who have PE have abnormal, but non-specific chest radiographic findings, including atelectasis and parenchymal areas of increased opacity [25]. So, chest X-ray is not an accurate diagnostic tool [10].…”

Postoperative shed blood retransfusion (autotransfusion) is a commonly used salvage method following major surgical operations, such as total knee arthroplasty (TKA). The systemic effects of shed blood are still unclear. We studied the effect of residual substances in the retransfused shed blood, on lung perfusion after TKA. Fifteen unilateral and one bilateral TKAs were performed with autotransfusion (the study group) and 15 unilateral and three bilateral TKAs were performed in a control group. Lung Xrays, arterial blood gases (ABG), D-dimer values, and lung perfusion scintigraphies were performed preoperatively and postoperatively. A mean of 300.0±335.6 ml of bank blood was needed in the autotransfusion group and a mean of 685.7±365.5 ml of bank blood was needed in the control group (p=0.001). There was a postoperative segmental perfusion defect at the lateral segment of the superior lobe of the left lung in one patient of the control group and he also had risk factors for thrombosis. Although both groups had a decrease in lung perfusion postoperatively, there were no significant differences among the groups regarding the lung perfusion scintigraphy, chest X-rays, ABG, and Ddimer values. In conclusion, although pulmonary perfusion diminishes following TKA, shed blood retransfusion does not add any risk to pulmonary perfusion. Résumé La retransfusion post-opératoire est souvent utilisée dans les interventions majeures comme les prothèses de genou. L'effet systémique du sang récupéré n'est pas très connu. Nous avons étudié les effets de cette transfusion sur la perfusion pulmonaire. 15 prothèses de genou unilatérales et une bilatérale étaient réalisées en autotransfusion avec un groupe de contrôle de 15 unilatérales et 3 bilatérales. Des radiographies pulmonaires, les gaz du sang, la valeur des Ddimer et des scintigraphies de la perfusion pulmonaire étaient faites avant et après l'opération. Une moyenne de 300,0+−335,6 ml de sang de banque était nécessaire dans le groupe autotransfusion et une moyenne de 685,7+−365,5 ml était nécessaire dans le groupe de contrôle (p=0,001). Il y avait un déficit segmentaire de perfusion chez un patient du groupe de contrôle et il avait aussi des facteurs de risque thrombotique. Bien que les 2 groupes avaient une diminution de la perfusion pulmonaire, il n'y avait pas de différ-ences entre les 2 groupes pour la scintigraphie pulmonaire, les radiographies, les gaz du sang et les valeurs des D-dimer. En conclusion, bien que la perfusion pulmonaire diminue à la suite de l'arthroplastie totale de genou, la retransfusion du sang répandu n'entraine pas de risque particulier.

Chest radiographic findings in patients with acute pulmonary embolism: observations from the PIOPED Study.

Abstract: Although chest radiographs are essential in the investigation of suspected PE, their main value is to exclude diagnoses that clinically mimic PE and to aid in the interpretation of the ventilation-perfusion scan.
