Final
All Pathology for Arteries
| Question | Answer |
|---|---|
| Ectasia | Due to natural processes (aging) Vessels become dilated, tortuous, and elongated Have plague and calcification present |
| Para-aortic Masses | Hypoechoic Usually lymphoma around the aorta |
| Aneurysm | Most common pathology of aorta Sac-like dilatation of an artery wall |
| Aneurysm Measurements | Most accurate is the transverse measurement Longitudinal measurements show the extent of the aneurysm |
| Types of Aneurysms | Fusiform Saccular Dissecting |
| Fusiform | Most common type Bulging may be on both walls of the aorta |
| Saccular | Less common Bulging on one wall of the artery |
| Dissecting | The tunica intima is separated from the tunica media. Intimal flap may occur because of the blood pushing the intima away from the arterial wall |
| Symptoms of Dissection | Sudden pain Irregular enlargement of artery Double lumen Tear Intimal flap |
| Clot | Aneurysms may contain clot or thrombus |
| Sizes of Aneurysms | Less than 5 cm - will change slowly- only grows about .5 cm over several years. 1% chance of rupture Over 6 cm - will grow about .5 cm every 3 - 6 months. 40% chance of rupture Over 7 cm - will probably rupture |
| LOOK FOR: (with aneurysm) | Location of the aneurysm with respect to the RENAL arteries. (Corrective surgery is possible below renal arteries) Clot or thrombus Measure in transverse and longitudinal Look for dissection |
