Single Hole High Flow Arteriovenous Fistula

A high flow pial arteriovenous fistula in a twenty-years-old girl is described. The arteriovenous communication corresponds to a single hole fistula on the right rolandic area, with a giant venous ectasia. The patient presented seizures and left hemiparesis as symptoms. The fistula was embolized with glue obtaining total occlusion of the shunt. Hypotension was induced and valsalva manoeuver was done during the glue injection to reduce the flow into the fistula, however 26 hours after the procedure the patient bled resulting in a fatal outcome. The purpose of this paper is discuss the presentation of Rendu-Osler-Weber (ROW) in children and the therapeutic guidelines.

Total occlusion of the abdominal aorta is unusual, and potentially catastrophic. It occurs in patients with advanced atherosclerotic occlusive disease, and can cause severe ischemic manifestations, depending on the site of obstruction. Prompt and appropriate diagnostic and therapeutic approaches are important whenever this condition is suspected, in order to avoid a fatal outcome. The development of a complex network of collaterals may prevent the manifestation of acute ischemic phenomena, and cause a delay in diagnosis and treatment. Here we report the clinical case of a 59-year-old man who was referred to our Department for evaluation of renal failure and refractory hypertension. Ultrasonography and 99mTc-DTPA scintigraphy showed a shrunken, non-functioning left kidney, while CT angiography and aortography showed the complete occlusion of the aorta from below the right renal artery down to the bifurcation of both common iliac arteries, with a critical stenosis of the origin of the right renal artery, an occlusion of the left renal artery as well as of the origin of the inferior mesenteric artery. The patient was referred to the surgery department for aorto-bifemoral bypass surgery and re-implantation of the right renal artery.

Subdural contrast effusion secondary to endovascular treatment is exceptionally rare and might be mistaken as subdural hematoma because of similar hyperattenuation on computer tomography. The authors present the case of a 13-month-old girl with a history of increased head circumference and developmental retardation. Cerebral digital subtraction angiography showed a high-flow pial arteriovenous fistula fed by multiple arteries on the right cerebellar surface, with occlusion of the right sigmoid sinus and severe stenosis of the left sigmoid sinus. Staged endovascular treatments were performed to eliminate the fistula. Follow-up head computer tomography scans performed 3 h after both procedures demonstrated typical high-density subdural effusion with computer tomography attenuation value similar to hemorrhage. These effusions did not aggravate the condition and disappeared spontaneously 32 h after the first treatment and 29 h after the second, respectively.

The Brain

Capillary malformation-arteriovenous malformation (CM-AVM) syndrome is a newly described entity characterized by autosomal dominantly inherited multifocal capillary malformations caused by RASA1 mutations (CM-AVM1) or EPHB4 mutations (CM-AVM2). Concurrent high-flow vascular anomalies in the brain are often present in the form of intracranial AVM or arteriovenous fistula (AVF). These high-flow lesions are often identified at or soon after birth because of the characteristic unique capillary malformations or a systemic disorder due to a high-flow shunt, such as respiratory distress or heart failure. However, de novo intracranial AVMs have not been reported in patients with CM-AVM syndrome. Herein, we report the case of a six-year-old boy with CM-AVM1 who had been treated for an intracranial pial arteriovenous fistula approximately five years previously, in whom a de novo intracranial AVM was identified on a follow-up angiographic study. To the best of our knowledge, this report is the first to document a de novo intracranial AVM in a patient with CM-AVM. We recommend careful neuroimaging follow-up even if initial neuroimaging screening is negative because of the risk of de novo AVM development.

Short Time

✓ The authors present the case of a 69-year-old man who suffered from bilateral cortical venous hypertension due to a brain pial arteriovenous malformation (AVM) with a high-flow fistula. The AVM became complicated by the development of a high-grade stenosis of the posterior superior sagittal sinus (SSS). A comparison of cerebral angiograms obtained at different times revealed that the severe SSS stenosis had developed within a 5-year period and was located distal to the nidus of the left parietal AVM nidus, away from the entrance of the dominant superior superficial cortical draining vein into the SSS. The high-flow fistula was occluded with detachable coils and the AVM nidus was further embolized with acrylic. The SSS stenosis was mechanically dilated by means of balloon angioplasty and stent placement. This case provides angiographic evidence to support the hypothesis that a pial arteriovenous fistula in an adult can cause high-flow occlusive venopathy in a major sinus within a relatively short time and that this acquired high-flow occlusive venopathy can develop at an atypical location distant from the nidus of the AVM.

Purpose: We report a case of a pediatric patient developing a delayed-onset scalp arteriovenous fistula (AVF) and pseudoaneurysm managed with a new technique. Technique: A 10-year-old boy presented to the outpatient clinic complaining of a growing pulsatile mass in the right side of the skull after head trauma 6 months ago. He had no neurological deficits. Imaging studies revealed scalp AVF with pseudoaneurysm. The arterial feeding was from the right temporal artery, while the blood was drained into the superior sagittal sinus and the facial vein. The fistula was occluded successfully by a microvascular plug (MVP). Follow-up angiography 1 year later showed that the AVF was no longer seen with complete embolization of pseudoaneurysm, total occlusion of the abnormal vessels, and the absence of MVP migration. Conclusion: To the best of our knowledge, we report the first case of successfully using MVP to treat scalp AVF. The MVP is a novel technique with its unique ability to achieve rapid, safe, effective, and permanent vascular occlusion through a single device. Besides, the possibility of delayed-onset traumatic vascular injuries should be considered in a patient with head or facial trauma.

Renal artery aneurysm (RAA) concomitant with a renal arteriovenous fistula (RAVF) has been infrequently reported in the literature. We report a case of a 42-year-old man suffering from a giant RAA combined with a congenital high-flow RAVF. The contrast-enhanced CTA showed a 12.7-cm RAA synchronous with an RAVF between the right renal artery and a draining vein. After a comprehensive preoperative assessment, an endovascular approach was decided. Successful embolization was performed using an Amplatzer vascular Plug, and multiple coils. Completion angiogram demonstrated no flow into the RAA. The results of longterm follow-up demonstrate that endovascular techniques are safe and effective for the management of RAAs combined with high-flow RAVF.
