[A iatrogenic arteriovenous fistula following laminectomy. A rare differential diagnosis of heart failure].
An abdominal murmur was first heard in a now 46-year-old man four years after laminectomy at the age of 21. Signs of right heart failure and, ultimately, of global heart failure developed progressively and increasingly 20 years later. Echocardiography demonstrated enlargement of the right heart cavities, and atrial fibrillation was diagnosed. Cardiac catheterization revealed the typical picture of high output failure (cardiac output 13.9 l/min). Intra-arterial subtraction angiography demonstrated a fistula between the left iliac artery and vein. After operative closure of the fistula the signs of heart failure disappeared. Six months later a residual but insignificant fistula was still present, as well as persistent atrial fibrillation. Medical treatment having failed cardioversion successfully re-established sinus rhythm and the patient became symptom-free. Arteriovenous fistula after laminectomy is a rare cause of heart failure and often diagnosed very late. The prognosis is good once the fistula has been closed.
