Changes

* [[Aortic Aneurism]]: Most are abdominal, most are below the renal arteries. Different types of repair (open vs endovascular), when to intervene (> 5.5 cm, rapidly enlarging, or causing organ damage), one time screening abdominal US recommended in ever smokers ages 65-75.

* [[Aortic Dissection]]: Stanford classification: type B (post left subclavian and descending aorta) is medically managed; type A (ascending aorta to the left subclavian or beyond) is a surgical emergency.

* [[Deep Venous Thrombosis]]: Virchow's triad, mostly occur in the legs, DVTs leading to PEs are usually in the femoral veins. Hofman's sign is neither sensitive or specific. Risk stratify based on Well's score, then get D-dimer (sensitive, not specific) if pre-test probability is low to rule out DVT. Can give therapeutic dose heparin if pre-test probability is high.
