  • Evaluation of the Anterior Ethmoidal Artery by 3D dual volume rotational digital subtraction angiography and native multidetector CT with multiplanar reformations. Initial findings.
    European radiology, 2006
    Co-Authors: Ignazio Pandolfo, Sergio Vinci, Ignazio Salamone, Francesca Granata, Silvio Mazziotti
    Abstract:

    Our purpose is to codify the Anterior Ethmoidal Artery (AEA) course and its relationship with adjacent structures. Twenty patients with cerebrovascular disease underwent selective internal carotid dual volume angiography. Fusion of the vascular and bony images was obtained successively on a second console. MDCT of the cranium was performed in all patients. To identify the AEA course, multiplanar CT reformations were obtained. In all cases the entry-point of AEA and its course were identified by means of dual volume angiography. The information was confirmed by MDCT. In a second phase, we studied another 78 patients affected by inflammatory disease and polyposis only by means of MDCT, in order to confirm the previous data obtained by comparison between angiography and MDCT. In this second phase, 110/156 vessels were indirectly detected by means of visualization of the Ethmoidal entry point. In the remaining cases, AEA was directly shown due to integrity of the thin Ethmoidal bone lamellae or bony canal. Dual volume angiography is essential to identify the course of the AEA (standard of reference for the interpretation of CT). In patients with benign rhinosinusal pathology, where invasivity techniques are not justified, MPR reconstructions were of pivotal importance in the evaluation of the course of the Artery with particular reference to its relationship with the frontal recess.

  • Evaluation of Anterior Ethmoidal Artery by 320-slice CT angiography with comparison to three-dimensional spin digital subtraction angiography: initial experiences.
    Korean journal of radiology, 2012
    Co-Authors: Juan Ding, Gang Sun, Zhao Hui Peng, Xu Ping Zhang
    Abstract:

    Objective To explore the usefulness of 320-slice CT angiography (CTA) for evaluating the course of the Anterior Ethmoidal Artery (AEA) and its relationship with adjacent structures by using three-dimensional (3D) spin digital subtraction angiography (DSA) as standard reference. Materials and methods From December 2008 to December 2010, 32 patients with cerebrovascular disease, who underwent both cranial 3D spin DSA and 320-slice CTA within a 30 day period from each other, were retrospectively reviewed. AEA course in ethmoid was analyzed in DSA and CTA. In addition, adjacent bony landmarks (bony notch in medial orbital wall, Anterior Ethmoidal canal, and Anterior Ethmoidal sulcus) were evaluated with CTA using the MPR technique oriented along the axial, coronal and oblique coronal planes in all patients. The dose length product (DLP) for CTA and the dose-area product (DAP) for 3D spin DSA were recorded. Effective dose (ED) was calculated. Results The entire course of the AEA was seen in all 32 cases (100%) with 3D spine DSA and in 29 of 32 cases (90.1%) with 320-slice CTA, with no significant difference (p = 0.24). In three cases where AEA was not visualized on 320-slice CTA, two were due to the dominant posterior Ethmoidal Artery, while the remaining case was due to diminutive AEA. On MPR images of 320-slice CT, a bony notch in the orbital medial walls was detected in all cases (100%, 64 of 64); Anterior Ethmoidal canal was seen in 28 of 64 cases (43.8%), and the Anterior Ethmoidal sulcus was seen in 63 of 64 cases (98.4%). The mean effective dose in CTA was 0.6 ± 0.25 mSv, which was significantly lower than for 3D spin DSA (1.3 ± 0.01 mSv) (p Conclusion 320-slice CTA has a similar detection rate for AEA to that of 3D spin DSA; however, it is noninvasive, and may be preferentially used for the evaluation of AEA and its adjacent bony variations and pathologic changes in preoperative patients with paranasal sinus diseases.

  • Transcaruncular electrocoagulation of Anterior Ethmoidal Artery for the treatment of severe epistaxis.
    The Laryngoscope, 2011
    Co-Authors: Eduardo Morera, Christian Artigas, Francisca Trobat, Luis Ferrén, Manuel D. Tomás
    Abstract:

    Objective: The irrigation of the upper third of the nasal fossa is supplied by the Anterior Ethmoidal Artery. We describe a surgical technique to deal with epistaxis due to Anterior Ethmoidal Artery bleeding. Patients and Methods: From January 2006 to March 2010 transcaruncular coagulation of the Anterior Ethmoidal Artery was done on nine patients with epistaxis of the upper third of the nasal fossa. Results: The procedure was successful on all cases. No bleeding relapse, major complications, or nasal or orbital sequelae were present in any of the patients. Discussion/Conclusions: Transcaruncular electrocoagulation of the Anterior Ethmoidal Artery is a safe and effective technique to deal with upper third nasal fossa bleeding. Laryngoscope, 2011

  • superior oblique palsy as a complication of Anterior Ethmoidal Artery ligation
    Archives of Ophthalmology, 1991
    Co-Authors: Linda M Christmann, Mitchell J Wolin
    Abstract:

    To the Editor. —We read with interest the article by Couch et al1in the August 1990 issue of theArchives. It is especially important in reporting complications of surgery that one document compelling evidence that the problem was not preexisting and appropriate examinations were performed to relate the "complication" to the surgery performed. In the cases reported by Couch et al, the authors did not discuss the possibility that breakdown of a preexisting vertical phoria may have caused these patients' diplopia.2Studies of superior oblique palsy have documented that one of the most common, if not the most common,3causes of superior oblique palsy is congenital. One may distinguish acute from chronic palsies by review of old photographs for head tilt, measurement of vertical fusional amplitudes, and spread of comitance. In case 1, no mention is made of preexisting head tilt or vertical fusional amplitudes. The
