A 38 year old previously healthy male presented to our ER complaining of a 2 day history of worsening left arm pain and mild shortness of breath. On examination a discolored left arm was noted and markedly reduced/absent pulses. The patient was afebrile and the only abnormal laboratory investigations was a D-Dimer of 1500 ng/ml. CT-angiography showed a totally occluded left axillary artery and partial occlusion of the brachial artery - likely embolic. Bilateral pulmonary embolism noted on subsequent CT scan.\nHeparin infusion was initiated and a surgical embolectomy performed successfully. The patient was admitted to the ICU for observation management. The patient recovered and was discharged after 2 weeks.
A 60 year old hypertensive male presented to our institution with significant respiratory distress. He was subsequently intubated in the ER due to deteriorating respiratory status and reduced level of consciousness. On day 8 of his ICU course, the left lower limb appeared dusky and mottled up to the mid-thigh (). The right distal forefoot displayed a well demarcated discoloration.\nCT angiography revealed; Infra-renal aortic left sided eccentric, non-calcified atheromatous plaque. Significant occlusion of the left common iliac artery extending to infra-popliteal arteries. A joint decision was made to avoid surgery given the poor prognosis associated with severe acute respiratory distress syndrome and high inotropic support. The patient expired the following morning.
