The occurrence of complications of intracranial arteriovenous malformation (AVM) during labor induction is relatively uncommon. Intracranial AVM can cause convulsions, headache, focal neurological deficits and intracranial hemorrhage if ruptures. We present a 33-year-old parturient with history of paroxysmal supraventricular tachycardia, who was admitted for labor induction. She experienced a bout of convulsion following a 30-min oxytocin infusion, by which time it was three and half hours since she was given the test dose of epidural analgesic. She also denied having history of convulsions or preeclampsia. Magnetic resonance imaging (MRI) of brain demonstrated a cerebral AVM in the left frontal base without signs of intracranial hemorrhage or brain edema. The obstetrician opted for Cesarean section in order to avoid stress during vaginal delivery. The surgery was successfully performed under general anesthesia without hemodynamic fluctuations or neurological complications. We discuss the possible mechanisms of the convulsions attack in this patient and the ensuring anesthetic management for the Cesarean section she sustained.

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Cerebral Edema l: Introduction

Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
