Answer 21

Lung cancer

Question 22

Ideal positioning of IVC filter

Answer 22

Infrarenal IVC in normal circumstances, to prevent clot reaching and obstructing renal veins.

Fractures of the distal pole are less common than proximal pole. Proximal fragment at risk of AVN. Commonly caused by fall on outstretched hand.

Question 29

Vessel dissection post angioplasty

Answer 29

Will be a degree of dissection in all vessels after angio. Next step is to measure pressure gradient. If no significant gradient, all is well. Should be <10mmHg
