BACKGROUND AND PURPOSE Secondary expansion of hematoma after spontaneous intracerebral hemorrhage occurs frequently and early with the potential sequelae of functional deterioration or death. The aim of this topical review is to give a summary of current evidence- and experience-based options to avoid or attenuate hematoma expansion. METHOD We reviewed the literature of the past 10 years on e...

Traumatic aneurysms comprise less than 1% of all intracranial aneurysms. Most of these aneurysms are actually false aneurysms, or pseudoaneurysms, which are caused by the rupture of entire vessel wall layers, with the wall of the aneurysm being formed by the surrounding cerebral structures. Traumatic pseudoaneurysms of the middle meningeal artery are also rare. Only four cases have been reporte...

BACKGROUND AND PURPOSE Minimizing hematoma growth in high-risk patients is an attractive strategy to improve outcomes after intracerebral hemorrhage. We tested the hypothesis that desmopressin (DDAVP), which improves hemostasis through the release of von Willebrand factor, improves platelet activity after intracerebral hemorrhage. METHODS Patients with reduced platelet activity on point-of-ca...

The incidence of anticoagulant treatment (AT)-related intracerebral hemorrhage (AT-ICH) is increasing in consequence of the increased incidence of ischemic stroke due to an aging population. AT-ICH is associated with a risk of ongoing bleeding, death, or disability. Cerebral amyloid angiopathy (CAA), a common pathological finding among the elderly that is associated with macro- and microscopic ...

A new angiographical classification of primary intracerebral hemorrhage is presented. We have clarified the predilection sites of intracerebral hemorrhage and the advancing direction of the hematoma by studying autopsy cases. Furthermore, we tried to detect the presence or absence of destruction of the internal capsule and ventricular rupture by means of angiography. Our classification, introdu...

A 19-year-old man with mitral valve endocarditis and prolapse, intracerebral and intracerebellar hematoma, and a mycotic cerebral aneurysm underwent emergency mitral valve replacement during minimal cardiopulmonary bypass (total priming volume, 800 mL; autologous retropriming, activated clotting time <300 seconds) 1 day after undergoing endovascular coil embolization of the aneurysm. Postoperat...

Arteriographically Visualized Extravasation in Hypertensive Intracerebral Hemorrhage • Seven cases are reported in which extravasation of contrast medium from the lateral lenticulostriate artery was observed on cerebral angiography performed in the early stage of hypertensive intracerebral hemorrhage. We advance the theory that continuous bleeding from the ruptured artery with mechanical destru...

The authors report the complication that occurred after stereotactic catheterization in a 71-year-old patient with a spontaneous intracerebral hematoma (ICH). After stereotactic catheterization, a subarachnoid haemorrhage (SAH) was found in the post-operative CT scan. An SAH is a rare complication related with stereotactic catheterization. We investigated the cause and reported about a newly oc...

BACKGROUND AND PURPOSE A spot sign is a bright spot on computed tomography angiography source images, which is predictive of hematoma growth in spontaneous intracerebral hemorrhage, although the cause of the spot sign is unclear. Our aim was to investigate the spot sign seen on computed tomography angiography and a striate artery, which is a presumed site of intracerebral hemorrhage bleeding or...
