Peripheral Vascular Problems Flashcards
Best way to evaluate ischemia of the left colon and rectum
Sigmoidoscopy
For patients undergoing a long complicated operation, which is the most appropriate diagnostic test to evaluate the cause of oliguria?
Left heart preload pressures
Keep wedge pressures near 15 mmHg
Repeated bouts of cellulitis
Lymphedema
Indications for carotid endarterectomy
– Symptomatic carotid arteries more than 50% diameter reduction
– Asymptomatic carotid arteries more than 80% reduction
Patient is taken to the operating room for an embolectomy of the left popliteal artery. Which additional procedure should be performed?
Fasciotomy of all compartments in the leg
Which signs or symptoms of arterial insufficiency qualifies a patient for reconstructive arterial surgery of the lower extremity?
Limb loss – gangrene
Most appropriate medical management for atherosclerosis?
Aspirin
Subclavian steel syndrome called by which hemodynamic abnormality?
Atherosclerotic Occlusion of the subclavian artery proximal to the vertebral artery
What test is most predictive of postoperative ischemic cardiac events following surgery?
dipyridamole-thallium imaging showing reversible perfusion defects
Most common peripheral artery aneurysm?
Popliteal artery aneurysms – bilateral and 53% of patient
What is the management of popliteal artery aneurysms?
May present with chronicling ischemia or acute thromboembolism. All symptomatic popliteal aneurysms should undergo surgical repair with exclusion of the aneurysm (ligated and left in situ) combined with surgical bypass.
Asymptomatic popliteal aneurysms greater than 2 cm should be repaired surgically.
What is a limitation of the duplex ultrasound and evaluating a DVT?
Cannot image the proximal veins – iliac veins, IVC
Treatment for bilateral iliac disease or an infected aortic aneurysm or graft?
Axillofemoral bypass graft (alternative to aortofemoral procedures)
