A 10-year-old boy presented with a 4-month history of progressive wasting of left hand and forearm. The child had been initiated on hemodialysis through a left brachiocephalic fistula 10 months previously. The child had progressed to end-stage kidney disease within 6 months of presentation with biopsy-proven focal segmental glomerulosclerosis. At first use, the fistula was well functioning without any issues related to patency or blood flow during hemodialysis sessions. Ten months later, the child noticed symptoms of occasional numbness, poor grip, and relative coolness of the left hand as compared to the right. Fistula examination revealed a healthy fistula scar with 3 cm aneurysmal swelling in the left cubital fossa and thrill. Both the radial and ulnar pulses of the left upper limb were feeble and of low volume. Examination of the forearm revealed wasting of muscles of thenar and hypothenar eminences of the left hand, and left forearm [Figure 1]. There was a discrepancy in the palm size; the length and breadth on the left palm were lower than the right palm by 10 mm and 5 mm, respectively. A clinical diagnosis of ischemic steal syndrome secondary to arteriovenous fistula was made. Since the patient did not return for Doppler ultrasound and further follow-up, the diagnosis could not be confirmed.

Steal syndrome, characterized by ischemic symptoms of pain and paresthesia, occurs in <2% of radiocephalic fistulae and 5%–10% of brachiocephalic fistulae. While this condition is extremely rare in children, additional effect on growth of the affected limb is a risk during growing age, resulting in limb hypoplasia through vascular compromise. Reduced outflow or inflow to the fistula, obstruction,and/or lack of collateral blood supply result in the characteristic symptoms of steal syndrome. Diagnosis depends on clinical examination, and the clinical spectrum of ischemia is classified into four stages based on the severity of signs, including pallor, decreased or absent pulses, sensory or motor neuropathy, nail changes, distal discoloration, and/or ulcers. Mild cases are managed through frequent follow-up evaluation, with special attention to subtle neurologic changes and evidence of muscle wasting. If conservative measures fail, a stenotic lesion in the inflow feeding artery should be ruled out. Additional evaluations that should be considered include digital blood pressure, digital to brachial index, digital plethysmography, transcutaneous oxygen saturation, Doppler ultrasonography, and ultimately, an arteriogram. Definitive management is surgical or endovascular intervention that augments distal blood flow through various banding techniques. As a last resort, AV dialysis access closure should be considered.
