Three-Dimensional Rotational Dacryocystography for Imaging of the Lacrimal Draining System and Adjacent Anatomical Structures

Abstract

Purpose: A three-dimensional (3D) rotational angiography system was used to perform 3D dacryocystography (3DRD) as an adjunct to the conventional dacryocystography assisted by digital subtraction angiography (DSA). Methods:In 15 patients with severe epiphora, 3DRD was performed after inconclusive results from DSA-assisted dacryocystography. Results:3DRD was technically feasible and well tolerated in all 15 cases. In 5 out of 15 patients, 3DRD, in contrast to DSA-assisted dacryocystography, distinguished clearly between stenotic lesions of the canaliculi, lacrimal sac or nasolacrimal duct. In 10 cases, the simultaneous display of tear ducts and adjacent structures of the nasal cavity provided critical anatomical information for decision making between endoscopic and open dacryocystorhinostomy. Conclusions: 3DRD is technically feasible and adds important information to conventional DSA-assisted dacryocystography.

The Clinical Results of Endoscopic Dacryocystorhinostomy

“…The average age of the patients with dacryocystitis is reported to be between 41.5 and 63 in various studies (26)(27)(28)(29). Female patients have constituted the 89.1% of all the cases included in our study.…”

“…In patients with stenosis, early reflux through the punctum with a residual flow of CM to the nasal cavity is seen ( Fig. Furthermore threedimensional (3D) rotational angiography (3D RA) techniques provide valuable additional information regarding the site and degree of stenotic lesions and the adjacent anatomical structures (Lüchtenberg et al 2005). 13.3, 13.4).…”

Hallazgos nasosinusales por tomografía computada en dacriocistitis crónica pediátrica

“…La técnica de cirugía puede ser abierta o endoscópica, para lo cual es necesario evaluar las condiciones anatómicas y patológicas del aparato lagrimal y de los senos paranasales, estructuras íntimamente relacionadas, mediante tomografía computada (TC) de nariz y senos paranasales, que permita considerar una terapéutica perioperatoria adecuada, independientemente de su etiología. Para la evaluación del saco y de la vía lagrimal se utilizan la dacriocistografía (considerada de gran utilidad), imágenes tridimensionales 1 , la dacriocistografía por TC y la resonancia magnética 2,3 . No obstante, la TC de alta resolución desempeña un papel primordial en la evaluación del paciente, ofreciendo un mapa del área que será intervenida de cirugía endoscópica, pues los avances tecnológicos que inciden en la calidad de la TC permiten valorar y tomar decisiones efectivas, evitando de primera instancia tratamientos innecesarios y extensión de la lesión.…”
