Lesson 1Indications for revascularisation: endovascular vs open surgery, patient selection, peri-procedural planning, and outcomesExplains when to think of revascularisation for leg pain when walking and severe leg-threatening lack of blood. Compares keyhole and open surgery options, choosing right patients, planning around procedure, and real hopes for blood flow and function.

Points out goals, major studies, picking drugs with other illnesses, and ways to stick to treatment while cutting side effects.

Covers reading levels, traps like hardened arteries, and extra tests when ABI is wrong or unclear.

Stresses wave shapes, speed ratios, and spotting narrowings causing real blood flow issues.

Reviews images, rebuilds, and spotting fake signs that look like or hide artery disease.

Stresses body-wide risks, how they mix, leading to leg lack of blood and heart risks.

Focuses on standards, safety, reading points, and how these guide diagnosis, outlook, treatment in PAD.

Reviews monitoring tests, wound checks, when to refer, and tracking prevention to avoid leg loss and heart events.

Discusses how it helps, timelines, no-gos, and tracking sticking power, symptoms, function gains.

Tells PAD apart from nerve, muscle, vein leg pains, for right checks and quick specialist referrals.

Outlines urgent blood thinners, scans, and linking with surgeons for clot busters, removal, or quick fix.
