To retrospectively analyze our clinical data to determine the risk factors for thromboembolism, especially with unruptured posterior circulation coil embolization. ⋯ In cases of posterior circulation aneurysm coil embolization, if we place the guiding catheter into the side of the dominant posterior inferior cerebellar artery (PICA), then the risk of thromboembolism within the PICA territory could be higher. Accordingly, when faced with this situation, several solutions might be considered, such as changing the antiplatelet strategy or adding an intermediate catheter.

Case Reports
Spontaneous vertebral arteriovenous fistula mimicking brachial radiculo-plexopathy: A case report.
Vertebral arteriovenous fistulas (VAVFs) are uncommon high-flow communications between a vertebral artery and surrounding venous plexus that occur spontaneously or secondary to trauma. ⋯ This is a rare case of VAVF manifesting as a brachial radiculoplexopathy. Although rare, VAVF may be considered as a potential cause in patients presenting with similar symptoms.

Endoscopic-microvascular decompression (E-MVD) is a well-described treatment for trigeminal neuralgia (TGN), but there has been debate on the safety of intraoperative sacrifice of the petrosal vein (PV) due to concern for subsequent venous insufficiency. Our objective was to investigate the risk of PV sacrifice during E-MVD in TGN and subsequent postoperative complications and pain outcomes. ⋯ This study did not find higher complication rates in patients undergoing petrosal vein sacrifice during E-MVD for trigeminal neuralgia. In this series where petrosal vein was sacrificed only 59% of the time, it appears to be a safe technique, but larger studies will be needed to determine true incidence of complications after PV sacrifice.
