Treatment of Popliteal Artery Aneurysm with Acute Limb Ischemia and a Nonviable Limb (Rutherford Grade III)

Clinical Scenario

This protocol addresses popliteal artery aneurysm presenting with acute limb ischemia classified as Rutherford grade III — the stage at which the affected limb is nonviable or nonsalvageable at the time of presentation. The severity of ischemia at this grade fundamentally changes the management decision compared with salvageable presentations.

Key Consideration

Rutherford grade III identifies a limb that is not salvageable at presentation. In this setting, attempts at revascularization carry significant risks — including reperfusion injury and potential renal failure — associated with operating on a nonviable limb.

Management Approach

The evidence-based approach for this scenario moves away from revascularization toward a primary surgical intervention, with timing guided by the patient's individual clinical and physiologic findings. The complete structured protocol — including decision criteria, sequencing, and all clinical considerations — is accessible below.

Nonviable limbs (Rutherford grade III) require amputation.
Limbs that are not salvageable at presentation (Rutherford grade III) should undergo primary amputation rather than revascularization to avoid reperfusion injury, potential renal failure, and other complications attendant upon a nonviable limb.
