When acute upper limb ischaemia presents with motor or sensory loss — indicating a threatened limb — or when the affected limb is critical to the patient's quality of life, a specific intervention pathway applies. Conservative management alone is not the recommended course in these circumstances.

Clinical Scenario

This protocol covers acute upper limb ischaemia where the limb is threatened, evidenced by motor or sensory deficit, or where preserving limb function is essential to quality of life. In these presentations, anticoagulation alone is insufficient and intervention is indicated.

Treatment Approach (Partial Summary)

The primary treatment is surgical, supported by systemic anticoagulation — the full protocol specifies the operative technique, anaesthetic approach, intraoperative strategy, and the complete supportive care regimen.

Treatment Goals

The key clinical end-point is restoration of visible perfusion to the hand and return of a palpable wrist pulse.

For a patient with acute ischaemia of the upper limb, conservative treatment with anticoagulation alone is not recommended if the arm is threatened, or if limb function is important to quality of life.
Most patients with upper limb ischaemia are treated surgically by brachial embolectomy; bypass surgery is seldom required acutely.
Acute treatment is similar for upper and lower limb ischaemia: systemic AC; intravenous fluids; oxygen; and medical optimisation (e.g., management of AF).
Alternatively, the ischaemic hand can be placed in a sterile clear plastic bag during the surgery, and if embolectomy restores visible perfusion and a palpable wrist pulse, check angiography may not be needed.
