Aortic Thromboembolism
Systemic arterial thromboembolism
Juga dikenal sebagai: FATE, Feline Aortic Thromboembolism, Saddle Thrombus, Saddle Embolus, Systemic Arterial Thromboembolism
Singkatnya
Aortic thromboembolism, or saddle thrombus, is a sudden, life-threatening emergency in dogs and cats where a blood clot blocks blood flow to the hind limbs. This guide explains the causes, critical warning signs, diagnostic process, and intensive treatment options for this severe cardiovascular condition.
TL;DR. Trombus pelana: darurat mendadak yang memblokir aliran ke kaki belakang; nyeri ekstrem dan kelumpuhan.
Trombus berada di trifurkasi aorta.
Apa itu?
Saddle thrombus: cardiac embolus lodges at the aortic trifurcation, cutting hind-limb flow. Ischemia leads to rhabdomyolysis, nerve injury, paresis/paralysis, and extreme pain.
Penyebab dan faktor risiko
Cat: usually HCM with enlarged left atrium. Dog: hypercoagulable states (Cushing, protein-losing nephropathy, IMHA, neoplasia, sepsis, pancreatitis, etc.).
Tanda yang perlu diperhatikan
- Severe pain, hind paresis/paralysis, absent femoral pulses (cardinal)
- Cold limbs, pale/cyanotic pads, tachypnea, hypothermia (common)
- Muscle contracture, murmur/arrhythmia (occasional)
Bantalan kaki pucat atau kebiruan dan kaki dingin klasik.
Bagaimana dokter hewan mendiagnosis
Clinical five Ps (pain, paresis, pulselessness, pallor, poikilothermia). Echocardiography, abdominal ultrasound/Doppler, thoracic radiographs before diuretics, CK/AST, TEG if available.
Echo menunjukkan pembesaran atrium dan sering trombus atau asap.
Pilihan pengobatan
Opioid analgesia. Anticoagulation: heparin, LMWH; long-term clopidogrel, sometimes aspirin. Oxygen; cautious fluids. Monitor reperfusion injury (hyperkalemia).
Prognosis
Poor: high acute mortality/euthanasia; recurrences common.
Pencegahan
Early cardiac screening; clopidogrel if marked LA enlargement. Treat underlying disease in dogs.
Kapan menghubungi dokter hewan
Category-5 emergency: sudden hind-limb paralysis, crying in pain, cold pale paws, severe dyspnea.
