PVD Flashcards
- ABI
- Level of occlusion
Segmental pressures
- B- mode
- Doppler ultrasound
Duplex scanning
- Pre-op preparation
- Invasive
- Complication
Peripheral angiography
Any sudden decrease or worsening in limb perfusion causing a potential threat to extremity viability
Acute limb ischemia (ALI)
- sudden onset of symptoms
- known embolic source
- absence of preceding claudication
- presence of N pulses & pressures in contralateral / unaffected leg
Embolism
- associated with history of claudication
- local thrombosis
Thrombosis
Most definitive test for DVT in +/- symptomatic px~ gold standard
Venography
Telangiectasia, reticular veins, malleolar flare
C1
Skin changes as defined above with active ulceration
C6
Skin changes ascribed to venous disease
C4
Varicose vein
C2
Skin changes as defined above with healed ulceration
C5
Used in chronic venous insufficiency
Trendelenberg test
Absorb lymph
Terminal lymphatic capillaries
Conduits for transport
Collecting vessels
Inability of lymphatic system to accommodate CHON & fluid entering interstitial compartment (IC)
Lymphedema
Soft pitting edema
1st- accumulation in IC
Edema increase pronounced, non- pitting, spongy
2nd - local inflammatory response
Increase subQ fibrosis, scarring “elephantiasis”
3rd- recurrent infectious episodes
Tree trunk and buffalo hump are seen in:
Lymphedema
Anomalous drainage of right pulmonary vein
Sinus venosus
AV canal and mitral valve defect
Ostium primum
Most common on px , requiring surgery
Perimembranous ventricular septal defect
