Renal arteriovenous fistula (AVF) presents a rare but important condition that can be acquired, congenital, or idiopathic. [ncbi.nlm.nih.gov]

Discussion Renal AV fistula is an unusual presentation as discussed above. It is usually difficult to diagnose. Patients usually present with hypertension and hematuria [ 3 ]. [omicsonline.org]

RAVF may be asymptomatic or present as hypertensive cardiopathy, congestive heart failure, or severe renal hematuria. We present the case of a patient with a congenital RAVF as well as high-output congestive cardiac failure. [vasculardiseasemanagement.com]

Renal AVFs should be suspected when a history of image guided percutaneous renal biopsy is present. Ultrasound Renal AVFs are usually imperceptible in B-mode. [radiopaedia.org]

• Renal Artery Stenosis

  The most common etiologies of hypertension in neonates are renal artery thrombosis, renal artery stenosis, renal anomalies, coarctation of the aorta, and bronchopulmonary dysplasia. [accesspediatrics.mhmedical.com]

  Doppler ultrasound is highly specific in cases of transplanted renal artery stenosis, pseudoaneurysms, arteriovenous fistulas, and thrombosis with complete or partial artery or vein occlusion. [ncbi.nlm.nih.gov]

• Pertussis

  Recommended immunizations for dialysis personnel include: (a) Hepatitis B vaccine (b) Influenza vaccine, (c) Measles, mumps and rubella (MMR) vaccine, (d) Varicella vaccine and (e) tetanus, diphtheria with acellular pertussis (Tdap) vaccine [Table 12] [sjkdt.org]

• Heart Failure

  Renal AVFs are often asymptomatic but are occasionally accompanied by hematuria or heart failure. Transcatheter closure with embolization is a safe and effective treatment for renal AVF. [ncbi.nlm.nih.gov]

• Vascular Disease

  Although the indication for surgical treatment of renal vascular disease has decreased owing to the advancement of interventional techniques, there are still some risky cases for which surgical repair should be recommended. [ncbi.nlm.nih.gov]

• Diastolic Hypertension

  Increased renin secretion in this instance supports the proposed mechanism of diastolic hypertension with renal arteriovenous fistula. [ncbi.nlm.nih.gov]

• Wide Pulse Pressure

  The physical manifestations of this would be a relatively normal systolic blood pressure with a decreased diastolic blood pressure resulting in a wide pulse pressure. [en.wikipedia.org]

If assessed to be at risk for rupture, a workup for associated access infection should be considered and a surgical consult for aneurysm repair initiated. Dual antiplatelet therapy should be avoided in patients with AV fistula aneurysms. [hindawi.com]

Interventional embolization is currently the first line treatment for arteriovenous fistulas; however, the efficacy of repeated embolization remains controversial. [ncbi.nlm.nih.gov]
