The dual microcatheter technique is an alternative treatment for stent-assisted coiling in acutely ruptured wide-necked aneurysms because of no antiplatelet therapy. We assessed the safety and efficacy of this technique in ruptured wide-necked aneurysms. Between March 2008 and March 2016, 56 acutely ruptured aneurysms were treated with the dual microcatheter technique. The angiographic results, treatment-related complications, and clinical outcome were documented. Angiographic follow-up was available in 37 patients at a mean of 20...

BACKGROUND: Hybrid room treatment (HRT) provides the surgeon immediate intraoperative angiography control of aneurysm occlusion and vessel patency. Since it is relatively resource demanding, in clinical routine HRT is reserved for elective cases. However, since its introduction in our department in 2008, several random cases of ruptured intracranial aneurysms (IAs) have been treated in the HR. This study aims to compare the clinical and radiological outcomes of these cases with cases treated conventionally using a matched pair analysis...

OBJECTIVE: Patients undergoing open abdominal aortic aneurysm (AAA) repair are at risk of perioperative infections that can lead to subsequent complications. Our goal was to understand how an initial infectious complication influences the risk of subsequent complications in this cohort of patients. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2005 to 2012), we evaluated the relationship between three index infectious complications after open elective AAA repair (pneumonia, deep/organ surgical site infection, and urinary tract infection) and subsequent complications...

OBJECTIVE The presence, extent, and distribution of intraventricular hemorrhage (IVH) have been associated with negative outcomes in aneurysmal subarachnoid hemorrhage (SAH). Several qualitative scores (Fisher grade, LeRoux score, and Graeb score) have been established for evaluating SAH and IVH. However, no study has assessed the radiodensity within the ventricular system in aneurysmal SAH patients with IVH. Prior studies have suggested that hemorrhage with a higher radiodensity, as measured by CT Hounsfield units, can cause more irritation to brain parenchyma...

BACKGROUND: Intracranial aneurysms may rupture and are typically associated with high morbidity and mortality, commonly due to vasospasm after rupture. Once the aneurysm ruptures, the patient's cerebral blood flow may be disturbed during the acute phase, affecting cerebral circulation and thus cerebral perfusion prior to the onset of vasospasm. Fisher and Navarro scores are used to predict vasospasm, while World Federation of Neurosurgical Societies (WFNS) scores are used to predict patient outcomes...

Ikuo Hashimoto, Kazuhiro Watanabe
We previously reported the clinical usefulness of the mitral annular plane systolic excursion (MAPSE) to evaluate the left ventricular (LV) function in patients with Kawasaki disease (KD) in the acute-phase. However, the feasibility of the MAPSE z-score has not been evaluated in patients with acute KD. We prospectively studied 60 KD patients without coronary aneurysms. The MAPSE z-scores were calculated using our standard MAPSE data. Brain natriuretic peptide (BNP) was measured as a parameter of LV function...
