Module 6 : Peripheral Arterial System Part 2 Flashcards
what is a false aneurysm
- pulsating hematoma that originates from a leaking artery and confined by surrounding tissues not by arterial wall
what is the most common cause of a flaw aneurysm
- arterial puncture
- violent trauma or infection
what must there be in order to classify as a false aneurysm
- communicating channel between the main artery and pulsating mass
what are 4 sonographic features of false aneurysms
- swirling of color and communication tract
- spectral trace within the tract will have high velocities and spectral broadening
- spectral trace within the hematoma will have turbulent flow
- 1-5cm
what is the treatment of a false aneurysm
- size and location of channel important because can undergo compression treatment
- procedure is not fun and could result in arterial occlusions or venous thrombosis
- firmly compress with transducer for 10 minutes than rest then again
- can also inject thrombin into pseudo aneurysm
what is arteritis and what are the vessels it typically effects
- inflammation arterial wall
- tibia Artemis and distal arterioles
hat are the 3 types of arteritis
- takayasus
- temporal
- polyartierits
what’s the most common type of arteritis
- burgers disease
- mainly in men < 40 with heavy smoking
what is aortic coarctation
- congenital narrowing of the thoracic aorta may effect abd AO
- may result in LE ischemia
what is vasoplastic disorders/ cold sensitivity
- intermittent ischemia in the fingers or toes in response to cold exposure or stress
what is the cause of cold sensitivity
- idiopathic
- result of underlying disease
what can color duplex help with in cold sensitivity
- color duplex helps rule out obstructive disease or emboli in larger vessels as cause of symptoms
what are the 2 types of raynauds disease
- primary
- secondary
what is primary raynauds disease also called
- idiopathic
- spastics raynauds disease
what is primary raynauds disease
- intermittent digital ischemia caused by arterial spasm when exposed to cold temperatures
