RESUMEN
Basilar artery fenestration aneurysms are very rare and endovascular management of large and complex aneurysms is extremely challenging. Most of these type of cases are managed with stent assisted coiling, dual flow diverters (FD) and single FD with additional coiling of aneurysm and occlusion of one of the vertebral artery. Here, we report a case of large complex basilar artery fenestration aneurysm successfully treated with single FD using novel technique called "crossing flow diverter technique" without any additional coiling of aneurysm or occlusion of vertebral artery. Using this technique cost of procedure and procedural complexity inherent with other above mentioned techniques can be significantly reduced.

An anomalous common trunk giving rise to bilateral intercostal arteries at multiple levels is exceedingly rare and its association with spinal filar AVF and low-lying cord has not been reported so far. Here, we report this uncommon anatomical variation in a 60-year-old male who presented with paraplegia and on imaging found to have low-lying spinal cord with filar AVF and venous congestive myelopathy and discuss its embryological basis and associated malformations. Although rare, interventional radiologists should be aware of this entity, as these trunks may be a major source of bleeding in patients with hemoptysis, and also may be involved in vital spinal cord supply.
