We report a patient who had a callosal infarct, showed by Computer Tomography and Magnetic Resonance Imaging, without injury to the adjacent hemispheres. Angiography revealed an occlusion of both internal carotid arteries. Besides interhemispheric disconnection with unilateral left agraphia, left tactile anomia, left ideomotor apraxia and left ear auditivoverbal extinction, the patient showed signs of left hemineglect and astasia-abasia, both persistent.

Morphology-Based Risk Analysis of Catheter-related Thrombus After Pediatric Cardiac Surgery.
Ann Thorac Surg Short Rep

Department of Pediatrics, The University of Tokyo Hospital, Tokyo, Japan.
Background: Understanding the development of central venous catheter-related thrombus (CVCRT) is vital for the prevention of adverse events caused by thrombi after cardiac surgery in children. However, the risks associated with CVCRT remain controversial. This study analyzed the risk factors of CVCRT based on a detailed evaluation of its morphometric features and severity.

Subarachnoid haemorrhage from aneurysmal rupture is a common emergency in neurosurgery. Depending on aneurysm position, morphology, size, associated clot, and symptoms, it is either managed by endovascular occlusion or by clipping. Here we report the first known case of secondary Moyamoya phenomenon following the clipping of a supraclinoid internal carotid artery Aneurysm.

Biliary stent occlusion is due, in part, to biofilm formation by bacteria. However, previous culture-based approaches may not have revealed all microorganisms on the surface. Twenty-seven patients underwent endoscopic retrograde biliary drainage for the removal or replacement of plastic biliary stents.

Semmes-Murphey Neurologic and Spine Institute, Memphis, Tennessee, USA.
Background: Studies have described a first pass effect (FPE) where patients with successful recanalization after one pass experience better outcomes. Few studies have evaluated this in patients with large core infarctions.
Objective: To determine whether patients with large core infarcts undergoing mechanical thrombectomy in which first pass reperfusion is achieved experience improved outcomes compared with those who undergo more than one pass.

Vascular occlusive diseases remain a major health burden worldwide, necessitating a deeper understanding of the adaptive responses that mitigate their impact. Arteriogenesis, the growth and remodeling of collateral vessels in response to arterial occlusion, is a vital defense mechanism that counteracts fluid shear stress-induced vascular stenosis or occlusion. While physical factors driving arteriogenesis have been extensively studied, the specific cellular mediators involved are poorly understood.
