Abstract
PURPOSE: The main objective was to perform an image-guided (CT) assessment of the efficacy of the CAVI-T™ balloon to compress the sphenopalatine artery (SPA) on cadaver heads, for the management of epistaxis. The secondary objectives were to analyse the deployment and stability of this balloon according to the volume injected into the nasal cavity, to optimise its use. METHODS: A descriptive anatomical study was performed. The catheterization of the SPA was performed on four fresh-frozen heads with a SPA approach through the maxillary sinus, leaving the nasal cavity unscathed. Computed Tomography images were acquired without and with the balloon, inflated by injections of progressive volumes of diluted iodine, for optimal contrast with the surrounding tissues. We evaluated the positioning of the balloon according to two predetermined markers on the device. RESULTS: Out of 68 image-guided acquisitions, the CAVI-T™ balloon compressed the SPA in 88% of cases. The other nasal cavity structures were compressed in 86% to 100% of the cases, depending on the positioning of the CAVI-T™ balloon, therefore allowing a complete obstruction of the nasal cavity. The device remained stable upon inflation and did not obstruct the nasopharynx. CONCLUSION: The CAVI-T™ balloon provided effective compression of the SPA and the different structures of the nasal cavity.
