Peripheral Arterial Disease Cases Expose the Cost of Delayed Diagnosis

Peripheral arterial disease can begin with a sore calf, a painful foot at rest, or a wound that simply refuses to close. In everyday practice, those symptoms are easy to dismiss until the arteries supplying the legs have narrowed so far that tissue survival is threatened.

Paul Hardy’s story is a blunt reminder of how fast that process can become limb-threatening when it is left unrecognized. Diagnosed four years ago, the 62-year-old from Leicester underwent angioplasty to improve blood flow and later required a bypass operation after severe leg pain while walking made the disease impossible to ignore. He now manages the condition with medication and exercise, but his message is aimed at the people who have not yet reached that point: do not wait until the damage is irreversible.

Symptoms That Signal Ischemia, Not Ordinary Aches

PAD is caused by narrowing or blockage of the arteries in the legs. Once blood flow falls below what muscle, skin, and soft tissue need, symptoms move beyond inconvenience and into ischemic injury. Pain on walking, pain at rest, foot ulcers that do not heal, and visible changes such as thickened toenails or hair loss on the feet all point to reduced perfusion rather than a simple mechanical strain.

One sentence captures the danger plainly: untreated PAD can cost a leg.

Hardy said he delayed seeking care longer than he should have done. By the time he was assessed, he needed a “simple scan” and ultimately a bypass operation because the arteries had narrowed. His experience fits a familiar vascular pattern: symptoms start gradually, adaptation masks the severity, and then a threshold is crossed where revascularization becomes urgent rather than elective.

Early Testing Can Change the Course

The campaign in Leicester is built around a straightforward diagnostic tool: the ankle-brachial index (ABI). This test compares blood pressure in the arms and ankles and can identify impaired circulation before tissue loss or catastrophic events develop. In vascular medicine, ABI is valuable because it is quick, non-invasive, and capable of turning a vague complaint into measurable evidence of arterial disease.

A Doppler scan later revealed no detectable blood flow in the feet of Nic Olsen, whose story shows what happens when PAD advances unchecked. The 80-year-old from Tugby had been a keen walker and cyclist, yet over several years leg pain became unbearable. He also developed ulcers and cuts that would not heal, thickened toenails, and loss of hair on his feet — all consistent with chronic limb ischemia. After more than 20 visits to health professionals, including GPs, podiatrists, and orthopaedic specialists, the diagnosis finally arrived, but by then both legs eventually had to be amputated.

Limb Loss Reflects a System Failure, Not Just a Single Missed Visit

Olsen is now learning to walk again using prosthetics. His account makes clear how fragmented care can delay the recognition of vascular disease when symptoms are spread across multiple appointments and interpreted through different specialties. A foot ulcer may enter the system as a podiatry issue, a painful leg as an orthopaedic complaint, and walking limitation as an age-related problem, while the underlying arterial obstruction remains untreated.

Athanasios Saratzis, a research professor of vascular surgery at the University of Leicester and a vascular and endovascular surgeon at Glenfield Hospital, said there were up to 150 amputations a year linked to PAD at the hospital and most of them could have been avoided. That figure places the clinical burden in sharp relief. Each avoidable amputation represents not only a lost limb, but also the culmination of delayed detection, missed escalation, and insufficient public awareness.

Why PAD Carries Risk Beyond the Legs

PAD is not confined to the lower extremities. It is a marker of systemic atherosclerotic disease, which means patients face higher risk of heart attack and stroke as well as limb loss. When arterial narrowing appears in the legs, it often reflects the same disease process affecting other vascular beds. For that reason, identifying PAD early can change management in two directions at once: protecting the limb and lowering overall cardiovascular risk.

Saratzis said early diagnosis and assessment can make a significant difference to outcomes. That is because timely recognition opens the door to antiplatelet therapy, risk-factor control, exercise-based rehabilitation, and, when needed, revascularization before tissue death begins. The clinical window is narrow. Once ulcers deepen, infection sets in, or blood flow disappears entirely, the probability of salvage falls quickly.

Public Awareness Campaigns Need to Reach People Before the Ulcer Stage

The University of Leicester launched the “Are Your Legs Killing You?” campaign for six weeks, with support from doctors at Glenfield Hospital. Digital billboards, buses, and bus stops across Leicester, Leicestershire, and Rutland will carry the message in the hope that people with early symptoms seek assessment sooner. The university also hopes to roll the campaign out nationally, and interest has already come from the US, Canada, and parts of Europe.

The public-health logic is straightforward. PAD is common in older adults — affecting about 20% of people over 60 in the UK — yet awareness remains low. Many people normalize leg pain, dismiss non-healing sores, or assume foot changes are part of aging. In reality, those findings can be the first warning that arteries are failing to deliver enough blood to keep tissue alive.

Hardy and Olsen give the campaign its force because they show both ends of the same disease: one patient whose limb was saved after timely vascular intervention, and another whose disease advanced to bilateral amputation. The message for clinicians and patients is the same. Rest pain, non-healing ulcers, and exertional leg pain deserve vascular assessment, not delay.

The Cost of Waiting Is Measured in Tissue

PAD is treatable, but only when the diagnosis arrives early enough to act on. Once blood flow disappears from the feet, the conversation changes from prevention to salvage, and sometimes from salvage to prosthetics. The campaign’s value lies in pushing the first evaluation earlier, when ABI testing and vascular referral can still alter the outcome.
