Analysis of Puncture Site-related Complications in Japanese Registry of Neuroendovascular Therapy (JR-NET)3

A subgroup analysis of puncture site-related complications listed in the Japanese Registry of NeuroEndovascular Therapy 3, based on retrospective studies, was performed. Puncture site-related complications occurred in 315 (0.73%, average age: 65.2) of 36,708 patients out of all 43,303 registered cases. Carotid artery stenting (CAS, 95 patients, 1.1%, P <0.01) and extracranial percutaneous transluminal angioplasty (PTA, 21 patients, 1.4%, P <0.01) were associated with significantly higher incidence of puncture site-related complications. The incidence of complications correlated with the number of antiplatelet drugs (P <0.001). Although 40% of the puncture complications were treated conservatively, 13% were treated endovascularly and 5% underwent open surgery.
