Treatment of Acute Upper Limb Ischaemia (Rutherford Grade IIa) with a Non-Threatened, Viable Limb
Clinical Scenario
This protocol applies to acute upper limb ischaemia classified as Rutherford grade IIa, where the limb shows no immediate threat and the clinical picture permits a conservative rather than interventional approach.
Defining Features of This Presentation
- No motor or sensory loss in the upper limb
- No muscle tenderness on examination
- Audible arterial Doppler signals present at the wrist
- Upper limb is not threatened
- Upper limb function not critical to the patient's quality of life
Management Approach (Overview Only)
In this specific presentation, management is conservative and non-interventional. Systemic anticoagulation forms the core of the approach, supported by adjunctive measures. The complete regimen — including agent selection, monitoring requirements, and escalation criteria — is set out in the full structured protocol.
Clinical goal: the limb remains viable without deterioration on regular review over the following days.

- Some patients with upper limb ischaemia appear to have no immediate threat to their limb, (no motor or sensory loss, no muscle tenderness, audible arterial signals at the wrist on Doppler; Rutherford grade IIa) and conservative treatment with AC alone may be appropriate.
- 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.
- Acute treatment is similar for upper and lower limb ischaemia: systemic AC; intravenous fluids; oxygen; and medical optimisation (e.g., management of AF).
- If the decision is made to treat upper limb ischaemia conservatively with AC alone, the arm should be reviewed regularly over the next few days to ensure it does not deteriorate.
