A Trial Comparing Routine Versus Selective Use of Completion Angiography After Surgical Thromboembolectomy in the Treatment of Acute Lower Limb Ischemia and Their Impacts on Limb Salvage Rates
A Trial Comparing Routine Versus Selective Use of Completion Angiography After Surgical Thromboembolectomy in the Treatment of Acute Lower Limb Ischemia and Their Impacts on Limb Salvage Rates
this randomized controlled trial will compare the impact of routine use of completion
 angiography versus using it on selective bases after thromboembolectomy in patients with
 acute lower limb ischemia and their impact on limb salvage rates
Inclusion Criteria:

 -  Grade I (1) (viable) acute ischemia which there is no immediate threat of limb loss;
 the patient is presented with neither sensory nor motor weakness and there are audible
 Doppler signals in both arteries and veins.

 -  Grade IIA (2 A) (marginally threatened) acute ischemia which needs proper treatment to
 save the limb; the patient is presented with a minimal sensory loss, no motor
 weakness, inaudible arterial Doppler signals but the venous Doppler signals are still
 audible.

 -  Grade IIB (2 B) (immediately threatened) acute ischemia which needs immediate
 revascularization to save the limb; the patient is presented with a sensory loss
 associated with rest pain, mild to moderate motor weakness, inaudible arterial Doppler
 signals but the venous Doppler signals are still audible.

 Exclusion Criteria:

 -  Traumatic or iatrogenic acute limb ischemia

 -  Grade III acute ischemia (irreversible) with major tissue loss and major amputation is
 inevitable; the patient presented with sensory and motor loss, inaudible arterial and
 venous Doppler signals.

 -  Patients With occluded bypass graft.

 -  Acute limb ischemia due to intra-arterial injection

 -  Patients with chronic renal impairment (serum creatinine > 1.2) or with a history of
 contrast-induced nephropathy.

 -  Acute lower limb ischemia due to thrombosed aneurysms
