The improved knowledge of the clinical and haemodynamical aspects of extracranial arteriovenous malformations in the 18th century provided a foundation for the understanding and treatment of cerebrovascular pathology. It was not until the late 19th century that detailed clinicopathological reports of intracranial arteriovenous malformations were published. A seminal report by the Italian surgeon Francesco Rizzoli described Giulia, a 9-year-old girl who presented with seizures and an occipital pulsanting swelling in 1873. Rizzoli used Giulia's signs and symptoms to predict the complex angioarchitecture of her "arteriovenous aneurysm passing through the wall of skull". Postmortem examination confirmed the supposed diagnosis, and showed a direct communication between the hypertrophic branches of the ocipital artery and the transverse sinus. The clinical course of that case is briefly reviewed in this article and the diagnosis of this unusual arteriovenous shunt is discussed in light of current neurosurgical knowledge.
Penetrating extremity injuries can result in the development of arteriovenous fistulas (AVFs), whereby normal blood flow through the capillary bed is bypassed. Late complications of untreated AVFs include proximal arterial dilatation, venous congestion, congestive heart failure, and distal ischemia. We report the case of a 57-year-old man who was referred to us for treatment of a traumatic AVF with multiple sequelae, 34 years after he sustained a shrapnel injury to his right lower leg. We performed successful endovascular repair of this AVF with the patient under spinal anesthesia. Computed tomographic angiography (CTA) done 1 month and 6 months later confirmed AVF exclusion. Patients may present with sequelae of traumatic AVFs many years after their initial injury. Endovascular repair of AVFs offers several advantages over conventional repair and can be performed successfully even in the presence of complex anatomic abnormalities.
