Study Notes
Approach to the Vascular Patient
- Timing is crucial when taking history from vascular patients
- History should include: pain, weakness in extremities, neurosensory complaints (warmth, numbness, hypersensitivity), discoloration, swelling, tissue loss/ulceration, varicosities
- Medical history should include: hypertension, atherosclerotic disease (CAD, PAD, CVA, carotid stenosis), hyperlipidemia, diabetes mellitus
- Surgical history should be thoroughly reviewed
- Social history: smoking is a major risk factor
- Meticulous inspection and documentation of skin changes should be performed during physical exam
- Palpate pulses unilaterally (abdominal aorta), and bilaterally (carotid, brachial, radial, ulnar, femoral, popliteal, posterior tibial, & dorsalis pedis arteries)
- Auscultation for carotid & renal bruits (indicative of turbulent flow)
- Screening ultrasound for abdominal aortic aneurysm (AAA)
- Follow-up ultrasound for patients with known or suspected vascular disease or those who underwent vascular intervention
Pulse Examination Locations
- Femoral: midway between ASIS and pubic tubercle
- Popliteal: popliteal fossa, knee at 45° angle, with two hands
- Posterior tibial: 2 cm posterior to medial malleolus
- Dorsalis pedis: 1 cm lateral to extensor hallucis longus tendon
- Always compare sides
Arterial Disease
-
Aorta:
- Aneurysm: dilation that can lead to rupture
- Dissection: intimal tear leading to a false lumen
-
Peripheral arteries: typically affects limbs
- Peripheral artery disease (PAD)
- Aneurysm: most common in popliteal artery, followed by femoral artery
-
Extra-cranial cerebrovascular arteries:
- Carotid stenosis
- Vertebral artery compression
-
Visceral arteries: renal, splanchnic, & mesenterics
- Stenosis, occlusion, aneurysm, vasculitides
Peripheral Arterial Disease (PAD)
- Obstruction or deterioration of arteries other than those supplying the brain or the heart
- Commonly affects the lower extremity
- Major pathophysiologic process is atherosclerosis
- Patients typically present with claudication: pain with activity, that is relieved by rest, and reproducible with the same level of activity
- May present with non-healing wound
- Affects 20% of Americans ≥65 years old
- Increased risk with: obesity, non-white ethnicities, smoking, diabetes, HTN and HLD (same risk factors as atherosclerosis)
Pseudoclaudication
- Leg pain caused by nerve impingement (spinal stenosis) rather than arterial obstruction
- Aka neurogenic claudication
- Variable walking distances
- Positional relief (leaning forward)
Diagnosis of PAD – Ankle-Brachial Index (ABI)
- Ratio of ankle pressure to systemic (brachial) pressure
- BP cuff is inflated until pulse becomes inaudible via doppler
- Perform at posterior tibial, dorsalis pedis and brachial arteries
- Use the highest brachial pressure overall (systolic), and the highest ankle pressure per limb
