Unusual thrombosis and catastrophic antiphospholipid syndrome

Abstract

Manifestations of venous thromboembolic disease (VTE) are common in hospitalized patients, particularly in the intensive care unit. However, VTE is not limited to lower extremity deep vein thrombosis, possibly complicated by pulmonary embolism, and can occur in more severe forms or involve unusual or multiple localisations. The objective of this article is to review the unusual sites or severity of venous thrombosis. The problem of non-atherosclerotic arterial thrombosis will be discussed more briefly. Then we will review the catastrophic antiphospholipid syndrome, as its severity and complexity most often lead the patient to the intensive care unit.
