METABOLIC DISORDERS AND PULMONARY EMBOLISM

Overuse and underuse of pulmonary CT angiography in patients with suspected pulmonary embolism

Background: The aim of the present study was to evaluate the utilization and diagnostic yields of CT pulmonary angiography (CTPA) using the Revised Geneva score and Wells’ criteria, in patients with suspected pulmonary embolism (PE).    Methods: One hundred and twelve adult patients underwent CTPA for suspected PE were participated in this study. The outcome was positive or neg...

Normoxemia and pulmonary embolism.

In 1971, Szucs et al1 reported a series of 50 nonconsecutive angiographically proven cases of pulmonary embolism (PE), all of which with Pao2 80 mm Hg, ie, “hypoxemia.” They concluded that normoxemia effectively excludes the diagnosis of PE. In succeeding issues of CHEST, there quickly followed a dozen or more well-documented exceptions to this rule. This was one of the first of many such “fail...

Thrombophlebitis and pulmonary embolism.

ACUTE venous thrombosis and its conmplilAw eations continue to be a challenging problem to the physician. Ineomplete understanding of the pathogenetic mechanisms, lack of objective measures for diagnosis, and differences of opinion coneerning therapy are parts of this problem. These difficulties, however, should not discourage the physician in his attempts to diagnose and treat venous thrombo-e...
