“…As suggested by our case, high rSO 2 could alert to the possibility of AVF prior to the appearance of symptoms. Diagnosis of AVF is usually made with ultrasonography and Doppler studies 11 13 14. Contrast CT scan, MRI and conventional angiography are more invasive, expose children to radiation, require sedation, are more expensive and are, therefore, reserved for difficult cases 11 13 15.…”

SUMMARYThe use of an indwelling arterial catheter is standard practice in the postoperative monitoring of paediatric cardiac surgery patients. Arteriovenous fistula related to this procedure can be difficult to diagnose. Regional haemoglobin oxygen saturation (rSO 2 ) using nearinfrared spectroscopy and central venous oxygen saturation (ScvO 2 ) are monitored to follow the balance between oxygen consumption and delivery. Low values of these parameters are a sign of low cardiac output. High rSO 2 and high ScvO 2 are less frequently described. We report the discovery of an iatrogenic arteriovenous fistula in a neonate after cardiac surgery who had unexpectedly high values of renal rSO 2 and femoral ScvO 2 . High renal rSO 2 after femoral instrumentation should alert the physician to the possibility of arteriovenous fistula. BACKGROUND

Arteriovenous Fistula after Femoral Artery Puncture Leading to Pulmonary Edema: The Role of Ultrasonography

et al. 2012

Local complications of arterial puncture include hematoma, pseudoaneurysm and formation of arteriovenous fistula (AVF). The latter could cause ischemia of the particular extremity or can be hemodynamically significant especially in patients suffering from congestive heart failure. We report a case of femoro-femoral AVF after thin needle arterial puncture for blood drawing. The development of this iatrogenic AVF led to pulmonary edema. The patient stabilized completely after surgical closure of the AVF. The AVF was diagnosed by duplex Doppler ultrasonography and this method was also used for estimation of blood flow through the AVF. We discuss the role of ultrasound AVF diagnostics and the method of flow calculation.
