The incidence, etiologies, and avoidance of complications of pulmonary angiography in a large series.

Pulmonary angiography is sensitive and specific in the diagnosis of pulmonary thromboembolism, but it remains an invasive procedure. Experience with 1,350 pulmonary angiograms was reviewed to ascertain the incidence, etiologies, and avoidance of complications. There were three deaths, all of which were secondary to cor pulmonale in patients with pulmonary hypertension and right ventricular end diastolic pressure (RVEDP) equal to or greater than 20 mmHg. Other complications consisted of cardiac perforation in 14 patients and endocardial or myocardial injury in six without sequelae, 11 significant arrhythmias and five cardiac arrests successfully treated, minor contrast material reactions in 11 patients, and a few insignificant complications. Carefully performed pulmonary angiography is safe if one avoids injecting contrast material into a patient with an elevated RVEDP.

Angiographic evaluation of chronic pulmonary embolism.

In some patients acute pulmonary emboli may fail to resolve normally, resulting in chronic pulmonary embolism. This may lead to pulmonary hypertension, respiratory insufficiency, cor pulmonale, and death. The angiographic evaluation in nine patients with chronic pulmonary embolism who underwent embolectomy is presented. Particular emphasis on the predictive value of selective bronchial arteriography in four of these patients is considered. In chronic pulmonary embolism, pulmonary arteries distal to obstructed areas may remain patent and be supplied by hypertrophied bronchial arteries. Since back-bleeding of arterial blood from the bronchial circulation at surgery may predict the success of embolectomy, preoperative bronchial arteriography may be useful for predicting potential surgical success.

Chest radiographic-pathologic correlation in adult leukemia patients.

A radiographic-pathologic correlation study of adult leukemia patients was conducted to determine the frequency and radiographic appearance of leukemic involvement and related complications within the chest. One hundred thirteen autopsy protocols were examined. Radiographic correlation was obtained in 60 of these cases. Autopsy pulmonary findings included hemorrhage in 74% of the cases, infectious infiltrates in 67%, edema or congestion in 57%, and leukemic infiltration in 26%. Only 5% of the chest radiographs were normal. Alveolar or interstitial abnormalities were identified in 90%, pleural effusion in 40%, and lymphadenopathy in 17%. Correlation demonstrated pulmonary infection to be by far the most common cause of radiographic opacity. Because of its frequent occurrence, high associated mortality, and potential reversibility, pneumonia must always be considered first in the differential diagnosis of radiographic opacity in these patients.
