Background
- Steal syndrome = Distal hypoperfusion ischemic syndrome[1]
- Higher risk with more proximal fistulas[2]
- 10–25% of brachiocephalic and basilic artery fistulas
- 4.3–6% of forearm prosthetic implants
- 1–1.8% of radiocephalic fistulas
- Classically elderly woman with DM
- Patietn history may include revascularization or banding efforts that re-stenose
Clinical Features
- Distal extremity becomes ischemic due shunting of arterial blood to venous side
- Exercise pain, nonhealing ulcers, cool, pulseless digits
- 4 Stages
- Stage I: pale/blue and/or cold hand without pain
- Stage II: pain during exercise and/or hemodialysis
- Stage III: rest pain
- Stage IV: ulcers/necrosis/gangrene
Differential Diagnosis
AV Fistula Complications
- Clotting of AV fistula
- Infection of AV fistula
- Hemorrhage of AV fistula
- Vascular insufficiency from AV fistula
- AV fistula aneurysm/pseudoaneurysm
- High-output heart failure from AV fistula
Blue Digit
- Acute arterial ischemia
- Atheroembolism (AKA Blue Toe Syndrome)
- Arterial embolism
- Arterial thrombosis
- Vasospastic Disorders
- Raynaud’s disease
- Primary erythromelalgia
- Autoimmune
- Idiopathic
- Thromboangiitis obliterans (Buerger's disease)
- Chronic peripheral artery disease
- Atherosclerosis obliterans
Evaluation
- Initial diagnosis is clinical
- Confirmation by[3]:
- Digital blood pressure measurement
- Duplex ultrasonography
- Transcutaneous PO2 measurement
Management
- Percutaneous transluminal angioplasty (PTA)
- Surgery
Disposition
- Admit
