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
