Venous complications following petrosal vein sectioning in surgery of petrous apex meningiomas
Koerbel A et al. - In a study to assess the frequency of postoperative venous congestion-related complications following petrosal vein obliteration as well as on pre- and intraoperative findings related to them, it appears that preservation of the petrosal venous complex, especially of large caliber veins, should be attempted whenever possible to increase the safety of surgery. In cases of petrosal vein obliteration, effective brainstem decompression following tumour removal is essential to minimizing risk of cerebellar congestion. Methods- 59 pts with meningiomas involving the petrous apex were analyzed concerning the intraoperative preservation or sacrifice of the petrosal vein and postoperative complications related to venous occlusion.
Results- When a petrosal vein was occluded, in 9 of 30 cases venous-related complications occurred with a minor venous-congestion phenomenon in 7 cases and major complications in 2 cases.
- When the petrosal vein complex was preserved, there were no similar complications.
