Impact of hospital readmission site on outcomes in acute ischemic stroke patients undergoing mechanical thrombectomy: a nationwide analysis.

Background: Mechanical thrombectomy (MT) significantly improves outcomes in patients with acute ischemic stroke due to large vessel occlusion. There is limited understanding of how the site of hospital readmission after MT influences patient outcomes. Addressing this gap may be important for optimizing post-MT care and improving long-term outcomes for stroke patients.

Intracranial Dural Arteriovenous Fistulas.

Dural arteriovenous fistulas (DAVFs) are abnormal communications between meningeal arteries and dural venous sinuses and/or cortical veins. Although many fistulas are benign and do not require treatment, some may carry a significant risk of bleeding or cause symptoms and warrant treatment. This review provides a review of various aspects of intracranial DAVFs including epidemiology, pathophysiology, clinical presentation, imaging characteristics, classification, natural history, and management options.

Traumatic Pulmonary Arteriovenous Malformation Presenting as Spontaneous Hemothorax.

Pulmonary arteriovenous malformations (PAVM), also known as pulmonary arteriovenous fistulas, are abnormal connections between the pulmonary arterial and venous systems. The majority occur secondary to the congenital syndrome hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease. Trauma is an extremely rare etiology of PAVM, comprising less than 1% of all reported cases.

Pediatric Moyamoya Presenting as a Subarachnoid Hemorrhage from a Ruptured Anterior Cerebral Artery Aneurysm.

Background: The incidence of Moyamoya disease (MMD)-associated intracranial aneurysms ranges from 3% to 14% in adult patients, whereas this complication has rarely been reported in children.

Case Description: We herein report the first case, to our knowledge, of an extremely rare subarachnoid hemorrhage presentation of a child with a ruptured anterior cerebral artery dissecting aneurysm secondary to a newly discovered, unilateral Moyamoya-like pathology.

Conclusions: MMD-associated aneurysms are extremely rare in children, and hemorrhage may be the initial presentation of the disease.
