Isolated cortical vein thrombosis with hemorrhagic infarction during the application of a transdermal estradiol patch: A case report.

Isolated cortical vein thrombosis (ICVT) is a rarer subtype of cerebral venous sinus thrombosis (CVST) that involves only the cortical veins without any thrombosis in the major cerebral veins or sinuses. Among the known causes of CVST are factors, such as being a young female or the use of hormonal preparations. This study presents a case of a 35-year-old female who underwent endometrial polyp removal 5 days before symptom onset and started using a transdermal estradiol patch.

Mechanical Thrombectomy Using Double Stent Retriever Technique for Acute Ischemic Stroke Following Embolism From the Pulmonary Vein Stump After Left Upper Lobectomy: A Case Report.

Acute ischemic stroke (AIS) following pulmonary lobectomy, which is traditionally attributed to air embolism and atrial fibrillation (AF), may occur after thrombus formation in the pulmonary vein stump (PVS). Herein, we document the mechanical thrombectomy (MT) of a carotid bifurcation occlusion post-left upper lobectomy (LUL) to manage AIS. A 76-year-old male with a history of diabetes, dyslipidemia, and a treated dural arteriovenous fistula at the transverse sigmoid junction, with no history of AF, successfully underwent LUL for a pulmonary tumor.

Impact of Cilostazol Pharmacokinetics on the Development of Cardiovascular Side Effects in Patients with Cerebral Infarction.

This study investigated the impact of polymorphisms of metabolic enzymes on plasma concentrations of cilostazol and its metabolites, and the influence of the plasma concentrations and polymorphisms on the cardiovascular side effects in 30 patients with cerebral infarction. Plasma concentrations of cilostazol and its active metabolites, and CYP3A5*3 and CYP2C19*2 and *3 genotypes were determined. The median plasma concentration/dose ratio of OPC-13213, an active metabolite by CYP3A5 and CYP2C19, was slightly higher and the median plasma concentration rate of cilostazol to OPC-13015, another active metabolite by CYP3A4, was significantly lower in CYP3A5*1 carriers than in *1 non-carriers (p = 0.

Remote hemorrhage after burr-hole surgery for chronic subdural hematoma: A report of two cases.

Background: The standard neurosurgical procedure for chronic subdural hematoma is a burr-hole surgery. Postoperative hemorrhage is one of the complications after burr-hole surgery. The hemorrhage generally occurs at the surgical site; however, remote hemorrhage is rare.

A novel technique to visualize true lumen in endovascular treatment of the occlusive carotid dissection and the usefulness of external-internal carotid collateral channel.

Background Dissection of the internal carotid artery (ICA) can cause occlusion or severe stenosis and is known to be one of the major causes of ischemic stroke in the young. Endovascular treatment is one of the useful options for carotid dissections, but passing the guidewire through the occlusion (lesion-cross) and confirmation of the true lumen are sometimes difficult. Case presentation A 40-year-old right-handed man complaining of dysarthria and gait disturbance consulted our hospital.

Fatal cerebral swelling immediately after cranioplasty: A case report.

Background: Cranioplasty is a standard neurosurgical procedure which is performed after decompressive craniotomy. Fatal complications associated with this procedure are not well documented. Here, we report a case of fatal cerebral swelling after cranioplasty and discuss the possible mechanism of this complication.

Dural Venous System in the Cavernous Sinus: A Literature Review and Embryological, Functional, and Endovascular Clinical Considerations.

The cavernous sinus (CS) is one of the cranial dural venous sinuses. It differs from other dural sinuses due to its many afferent and efferent venous connections with adjacent structures. It is important to know well about its complex venous anatomy to conduct safe and effective endovascular interventions for the CS.
