Aortic Thromboembolism
Systemic arterial thromboembolism
Ayrıca bilinen adıyla: FATE, Feline Aortic Thromboembolism, Saddle Thrombus, Saddle Embolus, Systemic Arterial Thromboembolism
Kısaca
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. Eyer trombüsü: arka bacaklara akışı bloke eden ani acil durum; aşırı ağrı ve felç.
Trombus aort trifurkasyonunda oturur.
Nedir?
Saddle thrombus: cardiac embolus lodges at the aortic trifurcation, cutting hind-limb flow. Ischemia leads to rhabdomyolysis, nerve injury, paresis/paralysis, and extreme pain.
Nedenler ve risk faktörleri
Cat: usually HCM with enlarged left atrium. Dog: hypercoagulable states (Cushing, protein-losing nephropathy, IMHA, neoplasia, sepsis, pancreatitis, etc.).
İzlenmesi gereken belirtiler
- Severe pain, hind paresis/paralysis, absent femoral pulses (cardinal)
- Cold limbs, pale/cyanotic pads, tachypnea, hypothermia (common)
- Muscle contracture, murmur/arrhythmia (occasional)
Soluk veya mavimsi yastıklar ve soğuk patiler klasiktır.
Veterinerler nasıl tanılar
Clinical five Ps (pain, paresis, pulselessness, pallor, poikilothermia). Echocardiography, abdominal ultrasound/Doppler, thoracic radiographs before diuretics, CK/AST, TEG if available.
Eko atriyum büyümesini ve sıklıkla trombus veya dumanı gösterir.
Tedavi seçenekleri
Opioid analgesia. Anticoagulation: heparin, LMWH; long-term clopidogrel, sometimes aspirin. Oxygen; cautious fluids. Monitor reperfusion injury (hyperkalemia).
Prognoz
Poor: high acute mortality/euthanasia; recurrences common.
Önleme
Early cardiac screening; clopidogrel if marked LA enlargement. Treat underlying disease in dogs.
Ne zaman veterinere başvurmalı
Category-5 emergency: sudden hind-limb paralysis, crying in pain, cold pale paws, severe dyspnea.
