Flashcards in TruLearn Question Pearls Deck (13)
Describe the scoring system for the Well's criteria (clinical risk assessment for PE)
- Clinical symptoms of DVT (leg swelling, pain on palpation) - 3.0 points
- Other diagnosis less likely than PE - 3.0 points
- Heart rate > 100 - 1.5 points
- Immobilization for > 3 days or surgery within 4 weeks - 1.5 points
- Previous DVT/PE - 1.5
- Hemoptysis - 1.0 points
- Malignancy - 1.0 points
High probability of PE > 6.0 points
Moderate probability of PE 2.0 - 6.0 points
Low probability of PE < 2.0 points
Modified Well's criteria
PE likely >4.0 points
PE unlikely < /= 4.0 points
What velocities on mesenteric duplex are consistent with >70% stenosis of Celiac or SMA?
Celiac: >200 cm/s
SMA: >275 cm/s
Treatment for Type B aortic dissection
- Strict blood pressure control with a beta-blocker
- Indications for Emergent Surgery
--- renal failure
--- signs of mesenteric ischemia
--- acute lower extremity ischemia
In Carotid Endarterectomy, what muscle may require division for distal control?
The posterior digastric muscle is divided for high lesions.
What is the MOST common location of peripheral aneurysms?
Popliteal artery = most common
Common femoral artery = 2nd most common
What artery supplies the posterior flap in BKA, and with good flow, decreases the risk for stump breakdown?
Sural Artery (branch of above-knee popliteal, supplies the gastrocnemius and soleus muscles)
What is the most likely cause of late access complications in AV fistula/graft?
Intimal hyperplasia of the graft-venous anastomosis
What causes Amaurosis fugax?
An isolated embolism to the retinal or ophthalmic artery, which is the first branch of the internal carotid artery. Chances of embolization to the ophthalmic artery are increased with ulcerative plaques.
What vascular injury is associated with posterior knee dislocation?
popliteal artery injury
What vascular injury is associated with Anterior hip dislocation?
femoral artery injury
What vascular injury is associated with Posterior shoulder dislocation?
What vascular work-up is required for posterior knee dislocation?
ABI >0.9 and Observation for 12-24 hours.
If patient alert and able to give a reliable exam, CTA no longer routinely recommended
