title: Unresolved major pulmonary embolism: importance of follow-up lung scan in diagnosis.
abstract: Unresolved major pulmonary embolism (UMPE) is an uncommon condition which causes pulmonary hypertension, cor pulmonale and death. An accurate and prompt diagnosis of UMPE is very important in the management of such patients with pulmonary embolectomy. Follow-up lung scans can lead to earlier diagnosis of UMPE, especially in patients who have a history of acute pulmonary embolism and present with pulmonary hypertension, respiratory insufficiency and cor pulmonale. We report a case of UMPE strongly suggested by follow-up lung scans and subsequently confirmed by pulmonary angiography and postmortem examination.
