Radial Artery Graft for Giant Common Carotid Artery Pseudoaneurysm After Carotid Artery Stenting.

Background: We present a patient who underwent left superior temporal artery (STA)-to-right middle cerebral artery (MCA) bypass using a radial artery (RA) graft with resection of a giant right cervical common carotid artery (CCA) pseudoaneurysm after carotid artery stenting (CAS) and discuss the treatment strategy and surgical procedure in detail.

Case Description: An 86-year-old male presented with sudden onset of altered consciousness and complete left hemiparesis. Magnetic resonance angiography and catheter angiography of the brain revealed occlusion of the right cervical ICA.

Incision of the anterior petroclinoidal fold during clipping for securing the proximal space of an internal carotid artery-posterior communicating artery aneurysm: a technical note.

Surgical clipping of an internal carotid artery (ICA)-posterior communicating artery (ICPC) aneurysm is often difficult in cases involving limited space to insert a clip at the proximal aneurysm neck hidden by the tent. In such cases, we perform incision of the anterior petroclinoidal fold to secure the proximal space for clip insertion. Between April 2013 and March 2018, we treated 89 ICPC aneurysm cases by clipping.

Bilateral suboccipital approach for a giant vertebral artery aneurysm.

Giant thrombosed aneurysms of the vertebral artery (VA) are difficult to treat. Moreover, marked tortuosity of the parent VA complicates determination of the surgical approach. We report the case of a 71-year-old male patient who presented with gait disturbance.

A 17-year-old girl with Klippel-Weber syndrome complicated with a pulmonary thromboembolism and RV thrombus.

A 17-year-old girl with multiple areas of skin hemangiomas that had been present since birth was referred to our institution complaining of sudden onset of dyspnea. Enhanced CT demonstrated a pulmonary thromboembolism and transthoracic echocardiogram showed a thrombus-like echo in the right ventricle. CT further revealed thrombi in the inferior vena cava (IVC) and peripheral vein.
