what cardiac condition is common in systemic sclerosis
pulmonary fibrosis
CT in pulmonary fibrosis would show what
Performing a high resolution CT Chest may identify ground glass changes or honeycombing which would be consistent with pulmonary fibrosis
This is the correct answer. AL amyloidosis (primary amyloidosis) results in amyloid protein deposition in various tissues in the body, such as kidneys and the heart. It can lead to a restrictive cardiomyopathy that appears “sparkling” on an echocardiogram. This man has presented with symptoms of heart failure with a preserved ejection fraction (HFpEF). Amyloid deposition also causes arrhythmias and conduction disturbances.
amyloidosis
A 65-year-old man presents to the emergency department complaining of excruciating pain in his left leg. This came on suddenly whilst he was walking. He has a history of poorly controlled Type 2 diabetes mellitus, Hypercholesterolaemia, Myocardial infarction and peripheral vascular disease affecting both legs. He has a 24 pack-year smoking history. On examination, his left leg is pale and cold. Popliteal, posterior tibial and dorsalis pedis pulses are not palpable in the left leg. Despite opiate analgesia, the patient remains in severe pain.
What is the single most likely diagnosis?
acute limb ischaemia
This is the correct answer. This patient is displaying three of the ‘6P’s’: pain, (perishingly) cold, and pulseless. He has had a thrombosis in situ in one of the main arteries in his left leg, which can be a complication of peripheral vascular disease. This represents acute-on-chronic ischaemia of his left leg where blood supply has been completely cut off. Without intervention, this will lead to death of the limb and eventually, the patient

explain intermittent claudication
This is the symptom of pain in the leg, which comes on with activity due to an inability to increase blood flow to the leg during increased activitiy. This is due to a narrowing of the arteries, typically due to atherosclerosis, causing peripheral vascular disease. Ischaemia in this situation is chronic but reversible on resting
You are the FY1 on vascular surgery. You are called to see a 58-year-old man who is two days post thrombolysis for acute limb ischaemia of his left leg. He is complaining of severe pain in his left leg, and his nurse reports that he has been requesting repeated doses of his PRN analgesia for the past few hours. He also complains of paraesthesia of the skin overlying his left leg.
On examination, his left leg appears red and swollen. There is severe pain on palpation of the muscles of the anterior aspect of his left leg, which feels tense and ‘woody’. Passive extension of his left toes produces excruxiating pain. Femoral, popliteal, posterior tibial, and dorsalis pedis pulse are palpable bilaterally.
Given the most likely diagnosis, what is the single best definitive management?
Four compartment fasciotomy
This is the correct answer. This patient has developed acute compartment syndrome secondary to reperfusion injury. This is a known complication which must be monitored for. A key examination finding is pain to passive stretching of muscles which is due to ischaemia.
Pulses are usually still felt, unless it is severe late compartment syndrome where intra-compartment pressures have exceeded systolic pressure. This can help distinguish it from an acutely ischaemic limb, which is pale, pulseless etc.
Prompt fasciotimy is the treatment; there are four compartments in the leg which require fasicial division
