Pathology_Flasback:
Embolism:
Free object that detached from distant source dislodge in a distant site (systemic or pulmonary circuits) .
#Origin_of_Emboli:
1-Thromboembolism (MCC):
Arterial source: atrial fibrillation and Atheroma.
Venous: deep venous thrombosis.
2-Gas Embolism.
3-Fat Embolism:either from fracture of long bones or aggressive liposuction.
4-Tumor fragment: e.g. Atrial Myxoma.
5-Amniotic Fluid Embolism.
6-Septic Emboli: IVDU, immunosuppresed and infective endocardtitis.
Where the #Emboli_Settle?
Systemic Embolization:
1- limb Ischemia.
2- Stroke.
3- Acute Mesentric Ischemia.
4-CRAO.
Pulmonary Circulation:
1-Saddle Embolism (huge size) : sudden death.
2- Small size: SOB and chest pain.
Paradoxical Embolism:
Pulmonary emboli pass to systemic circulation via patent #Foramen_Ovale.
