B: Acute limb ischaemia
Answer: B: Acute limb ischaemia 
Explanation: Fogay catheter is used to remove thrombus in acute limb ischaemiaThe aery (usually the femoral), bulging with clot, is exposed and held in silastic vessel loops. Through a transverse incision, the clot begins to extrude and is removed, together with the embolus, with the help of a Fogay balloon catheter. The catheter, with its balloon tip, is introduced both proximally and distally until it is deemed to have passed the limit of the clot.The balloon is inflated and the catheter withdrawn slowly, together with any obstructing material. The procedure is repeated until bleeding occurs.Ref: Bailey and love pg: 955
