Peripheral Arterial Disease: Medical Management Before the Scalpel

Absolutely, yes — particularly if the D-dimer is done after the acute phase, in a subacute presentation of a few days. Despite the test's high sensitivity, the result can come back in the low hundreds, nowhere near diagnostic. DVT is an anatomical problem, and for an anatomical problem the answer is to see it directly on ultrasound, not infer it from a blood marker. Vascular ultrasound is learnable within three to four months, and we train nearly all our trainees to do it routinely.

Laser ablation for superficial spider veins or one or two perforators has an excellent prognosis, and works well up to the perforator level. But if the saphenofemoral junction itself is regurgitant, open surgery to ligate the SFJ and clip the draining tributaries is usually the better option rather than relying on endovascular ablation alone.

In a fragile patient, angioplasty is best avoided below the knee — it gives reasonable short-term results but nothing very promising long-term. If intervention is genuinely needed, it is more often approached surgically, favouring a reverse femoro-tibial bypass using the patient's own saphenous vein over a prosthetic graft, and favouring open surgery over an endovascular approach in this territory. Below the knee: use the simpler, older, better-proven option, and know when not to intervene at all.

It is a vascular disease, but the vascular problem is not what is causing the pain in this elderly lady — and if medicines can manage the condition, there is no need to intervene, even if that is commercially a loss rather than a win. There has been a silent shift from a doctor-patient relationship to a doctor-hospital relationship, where a patient's data no longer stays with the treating doctor once they change hospitals. Old-school medicine — operating only when needed, never when not needed — is what should endure through that change.

Never confuse varicose veins with cellulitis and simply give a course of antibiotics to send the patient away — that is the wrongest possible thing to do, and it is not a constructed scenario. This happens regularly in real-life GP clinics, and any swollen leg deserves at least a Doppler ultrasound before it is written off as a skin infection.

Viral serology, since a viral aetiology is not uncommon in arterial aneurysms and arteritis, creatinine clearance to confirm the patient can safely receive contrast, and a CT peripheral angiogram, which is sometimes informative enough to support a request for a specific intervention.

When imaging shows no clear arterial cause for suspected disease, the workup should continue with lower-back imaging or a nerve conduction study, rather than intervening on an arterial finding that may not be the actual source of the pain.

Pentoxifylline as a peripheral arterial dilator, cilostazol to improve red blood cell flow through narrowed arteries, and a low dose of amitriptyline or another tricyclic to manage the pain component while preserving sleep and daily function.

The range runs from Fogarty catheter embolectomy and open arterial repair through to endovascular stenting from the aortic arch down to the peripheral arteries, increasingly performed in hybrid operating rooms that combine open access with endovascular technique.
