EVT is an effective method for treating PICA trunk aneurysms. The rate of permanent morbidity of the EVT is low. Conclusionįor PICA trunk aneurysms, the treatment choice should be assessed on a case-by-case basis. In addition, open surgery is still an important option. The risk of complications with EVT seems to be higher however, most complications are only transient or mild, and some are even clinically silent. Recently, some new devices, such as flow diversion and Barricade and Kaneka ED coils, can be used to treat PICA trunk aneurysms. Currently, the EVT mainly includes selective coiling with/without stent assistance and parent artery occlusion. Most aneurysms of the PICA trunk require aggressive treatment, especially those that have ruptured. Sometimes, the PICA can give rise to flow-related aneurysms in association with cerebellar arteriovenous malformations. Most PICA trunk aneurysms are dissecting aneurysms. The PICA can be divided into five segments (p1–5) the p1–3 segments are proximal segments, and the p4–5 segments are distal segments. We performed a review to expound upon EVT of PICA trunk aneurysms. Endovascular treatment (EVT) of aneurysms in the PICA trunk may be difficult and complex. Although most PICA aneurysms are located at the VA–PICA junction, a small proportion is located at the PICA trunk. Aneurysms can occur at any site along the PICA trunk. The posterior inferior cerebellar artery (PICA) generally originates from the vertebral artery (VA) and is the most complex cerebellar artery. ![]()
