Hyperacute ischemic stroke treated with carotid-carotid artery bypass surgery "case report".

Thrombolytic therapy using heparin, urokinase, and tissue plasminogen activator (tPA) has been the standard treatment for hyperacute ischemic stroke (HIS) with worsening carotid artery stenosis. In recent years, endovascular treatments (thrombectomy and carotid artery stenting) have attracted attention, and neurosurgeons are increasingly participating in these treatments. A 70-year-old Japanese male presented to our hospital with aphasia and right hemiparesis.

A case of acute coronary syndrome caused by delayed coronary ischemia after transcatheter aortic valve implantation.

An 84-year-old female patient suffered from dyspnea due to severe aortic stenosis. Several comorbidities and her advanced age made her acceptable for transcatheter aortic valve implantation (TAVI). The TAVI procedure was performed via a femoral access and a 26-mm CoreValve prosthesis (Medtronic, Minneapolis, MN, USA) was implanted.
