Strahlenexposition der strahlensensiblen Risikoorgane - Augenlinse, Speicheldrüse und Schilddrüse - bei Tränenwegsdarstellungen und -interventionen

Abstract: Radiation dose to the ocular lens, parotid gland and thyroid gland during fluoroscopy-guided DCP was 25 times higher than during diagnostic dacryocystography. The radiation dose to radiosensitive head and neck organs and tissues during fluoroscopy-guided DCP is much below the threshold dose for ocular lens cataract.

“…The mean exposure time in the present study was 4.3 minutes, an exposure comparable to that reported by Ilgit et al (2000) and Wilhelm (Wilhelm et al, 1998;Wilhelm, 2001). If 5 Gy is taken as the threshold dosage for induction of cataract as claimed by Henk (1993), then not even multiple nasolacrimal duct interventions pose a determinate risk of inducing cataract.…”

“…If 5 Gy is taken as the threshold dosage for induction of cataract as claimed by Henk (1993), then not even multiple nasolacrimal duct interventions pose a determinate risk of inducing cataract. The use of ionized radiation should therefore not constitute a contraindication for nasolacrimal duct intervention (Wilhelm et al, 1998).…”

“…X-ray exposure of the eye during dacryocystography has been calculated to be minimal and well below radiogenic dosage [9], even with exposure times as long as 7 minutes, which was not reached in any of the procedures in the present series.…”

“…Bei diagnostischen Dakryozystographien in digitaler Subtraktionstechnik im posterior-anterioren Strahlengang beträgt die Strahlenexposition für das im Strahlengang befindliche Auge 0,19 mGy, bei Tränen-wegsinterventionen im Mittel 5,87 mGy [17,61,63]. Legt man als Untergrenze der kataraktinduzierenden Strahlendosis die von Henk [14] angegebene Einzeldosis von 5 Gy an, so folgt, dass auch bei wiederholten Tränenwegsinterventionen nicht mit einer deterministischen Schädigung der Augenlinse in Form einer Strahlenkataraktbildung zu rechnen.…”
