embolics

Embolics is not a widely used term in clinical practice; the standard terms are embolus (singular) and emboli (plural), with embolism describing the resulting obstruction. An embolus is any intravascular mass that becomes dislodged and travels through the bloodstream, potentially lodging in a vessel and causing ischemia or infarction. Embolic events can involve arteries or veins and may affect any organ.

Common types of embolic material include thromboemboli (the most frequent), air emboli, fat emboli, septic emboli, tumor emboli, and amniotic fluid emboli. Sources vary: deep vein thrombosis or atrial fibrillation can generate intracardiac or systemic thromboemboli; trauma or vascular disease can release fat or atheromatous material. The clinical impact depends on the size and location of the occluding embolus; cerebral emboli can cause stroke, pulmonary emboli affect the lungs, and emboli to the mesenteric or peripheral arteries can cause organ or limb ischemia.

Diagnosis typically relies on clinical suspicion supported by imaging and laboratory tests. Imaging options include CT angiography, MR angiography, and ultrasound, depending on the suspected location. D-dimer testing can aid evaluation but is nonspecific. Treatment is etiology- and location-specific: anticoagulation for thromboembolism, thrombolysis or catheter-directed or surgical embolectomy in selected cases, and management of underlying risk factors. In pulmonary embolism, supplemental oxygen and supportive care are common; septic emboli require antimicrobial therapy, and tumor emboli may necessitate oncologic treatment. Prevention focuses on risk-factor modification and, where appropriate, prophylactic anticoagulation or mechanical filtration in high-risk patients. Prognosis varies with embolus size and organ involvement, underscoring the importance of rapid assessment and intervention.
