Feline arterial thromboembolism (FATE) is a devastating condition which occurs in cats secondary to underlying heart disease. The development of a large, poorly functional left atrium makes cats prone to developing blood clots, which if dislodged, travel through the body and occlude (block) blood vessels, most commonly those supplying the hindlimbs (caudal aorta & femoral arteries), and sometimes one of the forelimbs (brachial artery).
❔So how do we recognise this condition in our feline patients? Clinical signs include:
😱Acute loss of limb use (caudal aorta Vs brachial artery)
😱Intense pain, which causes vocalisation, tachypnoea and tachycardia in response.
The affected limb(s) will be:
☹️Cold
☹️Pulseless
☹️Have cyanotic (blueish/purpleish) paw pads & nail beds - spot the difference between a normal and FATE affected limb in the pictures of this post!!
👀 approximately 65% of FATE patients will present also being in congestive heart failure (think tachypnoea, dyspnoea and perhaps even a paradoxical breathing pattern if a pleural effusion is present due to the CHF)
