Patho Hemodynamic Disorders

Flashcards consist of section 2b, Hemodynamic disorders

Hemodynamic disorders

Interruptions of normal blood flow usually involving a thrombus or thromboembolus.

Thrombosis

Formation of a thrombus, which is organized unlike a random clot.

Thrombus

A thrombus is a blood clot that is attached to the wall of a blood vessel.

Lines of Zahn

Alternating layers of fibrin and cells found in growing thrombus.

Endothelial damage

Damage to the vascular lining exposing collagen, causing platelet aggregation.

Deep vein thrombosis (DVT)

A thrombus that forms in the deep veins of the legs, posing significant risk.

Thromboembolism

A part of an attached thrombus that breaks off and travels downstream, potentially causing ischemia.

Pulmonary embolism

A blockage in the pulmonary artery usually originating from leg veins.

Fibrinolytic system

The system in the body that breaks down fibrin, limiting clotting, and promoting blood flow.

Air emboli

Bubbles of gas in blood vessels that can cause critical complications during diving or surgical procedures.

Amniotic fluid embolism (AFE)

A rare condition where amniotic fluid cells enter the maternal circulation causing severe complications.

Fat emboli

Emboli that occur when fat globules enter the bloodstream, often following bone fractures.

Necrosis

Tissue death due to the loss of blood supply, often as a result of an infarction.

Myocardial infarction

A heart attack resulting from the occlusion of coronary arteries.

Cerebral infarction

A stroke caused by the disruption of blood supply to the brain.

Anticoagulants

Medications used to prevent blood clotting, such as heparin and aspirin.

Foreign body emboli

Emboli caused by objects such as bullet fragments or glass that can occlude vessels.

Flow abnormalities

Reduction or stasis of blood flow which can lead to thrombus formation.

Turbulence

Irregular blood flow that can increase the likelihood of thrombus formation.

Recanalization

The process by which blood flow is partially restored through an organized thrombus.
