Traumatic arteriovenous fistula of the middle meningeal artery treated with selective coil embolization: A case report.

Background: Dural arteriovenous fistulas (AVFs) are reportedly induced by trauma. We report a rare case of traumatic AVF with a direct shunt from the middle meningeal artery (MMA) to the middle meningeal vein (MMV) and multiple drainage routes after head trauma. The patient was effectively treated with selective coil embolization alone without liquid embolic material.

Delayed rupture of a large intracranial internal carotid artery aneurysm after flow diverter placement.

Background: Delayed rupture after flow diverter (FD) placement is a serious complication, and often it leads to death; however, the exact mechanism leading to the rupture remains unclear. Therefore, in this case, study, we report a case of delayed rupture after FD placement and discuss its causes.

Case Description: This study presents the case of a 69-year-old female with multiple aneurysms who underwent FD placement with coil embolization for a large intracranial internal carotid artery aneurysm.

[Carotid Artery Stenosis:Endovascular Techniques and Devices].

The increase in the number of carotid artery stenting cases can be attributed to a decrease in complications owing to the evolution of devices. In this procedure, the choice of the protection device and stent for each case is the main concern. Embolic protection devices(EPD)that prevent distal embolization can be divided into proximal and distal types.
