Abstract
Pulmonary embolism is a condition that occurs when an artery in the lung becomes blocked.
By far, the most common form of pulmonary embolism is a thromboembolism, that usually has migrated from a leg or pelvic vein once released into the venous circulation, thromboemboli are distributed to both lungs.
Amniotic fluid embolus continues to be one of the most feared and devastating complications of pregnancy. It can be neither predicted nor prevented. Its presentation is variable and, similar to other embolic phenomena, it is believed to encompass the spectrum of disease from a subclinical entry to one that is rapidly fatal.
Diagnosis is not so easy as no single non invasive test for pulmonary embolism is both sensitive and specific. Some tests are good for “ruling in” pulmonary embolism (e.g. Helical CT ) and some tests are good for “ruling out” PE (e.g. D-dimer ); others are able to do both but are often nondiagnostic (e.g. ventilation-perfusion lung scanning). For optimal efficiency, choice of the initial diagnostic test should be guided by clinical assessment of the probability of pulmonary embolism and by patient characteristics that may influence test accuracy. This selective approach to testing enables pulmonary embolism to be diagnosed or excluded in a minimum number of steps.
Treatment goals for deep venous thrombosis include stopping clot propagation and preventing the recurrence of thrombus formation, the occurrence of pulmonary embolism, and the development of pulmonary hypertension, which can be a complication of multiple recurrent PE.
The management of AFE is basically symptomatic and directed towards the maintenance of oxygenation, circulatory support and correction the coagulopathy.
Depending on the clinical presentation, full CPR protocol may be indicated.
