    Clinical features of middle cluneal nerve entrapment neuropathy

    Entrapment of the middle cluneal nerve (MCN), a peripheral nerve in the buttock, can elicit low back pain (LBP). We examined the epidemiology, clinical course, and treatment of MCN entrapment (MCN-EN).

    Angiographically confirmed stent over expansion in the internal carotid artery during stenting: incidence, predictors, and outcomes

    Selection of the appropriate diameter of stent is difficult in patients with the size mismatch between the internal carotid artery (ICA) and the common carotid artery (CCA). Although stent overexpansion (SOE) ...

    Endovascular treatment of tiny ruptured anterior communicating artery aneurysms

    Because of its high complication rate, the endovascular treatment (EVT) of anterior communicating artery (ACoA) aneurysms less than 3 mm in maximum diameter remains controversial. We evaluated EVT of tiny rupt...
