This episode explores arterial disease as a progressive, systemic process rather than an isolated vascular event. Listeners are guided through the pathophysiology, presentation, investigation, and surgical management of arterial disorders including peripheral arterial disease, acute limb ischaemia, aneurysmal disease, and carotid pathology.

The discussion emphasises history-taking that uncovers exertional symptoms, rest pain, and tissue loss, alongside examination findings that reflect compromised perfusion. Imaging modalities such as duplex ultrasound, CT angiography, and catheter angiography are explored in the context of decision-making rather than technology alone.

Surgical and endovascular options are discussed with a focus on patient selection, risk–benefit balance, and limb salvage. This chapter reinforces that arterial surgery is about restoring flow — but also about recognising when intervention serves function, comfort, and longevity rather than anatomy alone.
