Correlation of the Ventilation and Perfusion

چکیده

An irreversible change of the pulmonary perfusion was observed in a series of 100 chronic obstructive pulmonary disease patients studied with a pulmonary artery perfusion scan (PAPS). This perfusion involvement was greater in patients in whom the major respiratory component was pulmonary emphysema as opposed to either chronic bronchitis or bronchial asthma. A statistically significant correlation was noted between the extent of the perfusion changes, ventilatory and physical impairment of the individual. The PAPS offers an additional method for evaluating patients with chronic obstructive pulmonary disease. An original classification of the extent of the perfusion abnormalities as detected by the PAPS is presented.

Spurious lung perfusion ventilation defect on planar ventilation-perfusion scan detected by SPECT imaging

Pulmonary embolism (PE) is a preventable cause of morbidity and mortality which needs prompt recognition. Ventilation-perfusion (V/Q) scan is a well-established diagnostic test for evaluation of suspected PE. We report a 32-year-old woman with history of rheumatologic disease and acute dyspnea, who was referred for V/Q scintigraphy. The planar images revealed multiple mismatched defects through...

Diagnosis of thromboembolic disease: Combined ventilation perfusion lung scan and compression ultrasonography

The clinical management of pulmonary embolism and deep venous thrombosis of the legs are similar and requires prolonged anticoagulation therapy. The standard diagnostic approach in patients suspected of pulmonary embolism is ventilation-perfusion (V/Q) lung scan and compression ultrasonography to detect deep venous thrombosis. This retrospective study analyzed the role of V/Q lung scan an...

Correlation between ventilation and perfusion determines VA/Q heterogeneity in endotoxemia.

Endotoxin increases ventilation-to-perfusion ratio (VA/Q) heterogeneity in the lung, but the precise changes in alveolar ventilation (VA) and perfusion that lead to VA/Q heterogeneity are unknown. The purpose of this study was to determine how endotoxin affects the distributions of ventilation and perfusion and the impact of these changes on VA/Q heterogeneity. Seven anesthetized, mechanically ...

Pulmonary embolization causes hypoxemia by redistributing regional blood flow without changing ventilation.

To explore mechanisms of hypoxemia after acute pulmonary embolism, we measured regional pulmonary blood flow and alveolar ventilation before and after embolization with 780-micrometers beads in five anesthetized, mechanically ventilated pigs. Regional ventilation and perfusion were determined in approximately 2.0-cm3 lung volumes by using 1-micrometers-diameter aerosolized and 15-micrometers-di...

Correlation of myocardial Tc 99m-MIBI perfusion SPECT with coronary angiography in Namazi Hospital/Shiraz/Iran [Persian]

Coronary heart disease (CAD) is the leading cause of death specially among elderly. Coronary angiography is the best diagnostic method in the patients, but is unfortunately an invasive procedure with its inherent risks. Myocardial perfusion scan is a noninvasive and sensitive method for evaluation of CAD and is suggested by many investigators in recent years. In this study, 64 patients wh...

Fractal nature of regional ventilation distribution.

High-resolution measurements of pulmonary perfusion reveal substantial spatial heterogeneity that is fractally distributed. This observation led to the hypothesis that the vascular tree is the principal determinant of regional blood flow. Recent studies using aerosol deposition show similar ventilation heterogeneity that is closely correlated with perfusion. We hypothesize that ventilation has ...
