Hemorrhagic Stroke ll: Pathophysiology

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Hemorrhagic Stroke l: Introduction

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...

Blood and Nerve Supply to the Bones

Blood and Nerve Supply to the Bones

Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Bone Formation by Intramembranous Ossification

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

Summary

Spontaneous subperiosteal hematoma of the orbit is a rare complication of childbirth. This case highlights venous hyperpression during labor as a potential cause, emphasizing careful management in future pregnancies.

Area of Science:

Ophthalmology
Obstetrics
Radiology

Background:

Spontaneous subperiosteal hematoma of the orbit is an exceptionally rare condition, with only five cases previously documented in medical literature.
This study presents a novel case of this rare orbital complication, occurring as an immediate consequence of labor and delivery.

Observation:

A 28-year-old woman presented with acute onset exophthalmia, chemosis, and diplopia immediately following childbirth.
Computed Tomography (CT) scan confirmed the presence of a subperiosteal hematoma in the orbit.

Findings:

The patient experienced a favorable spontaneous resolution of the orbital hematoma.
No specific etiology was identified for the hematoma, suggesting venous hyperpression during labor as a potential cause.

Implications:

Due to the risk of recurrence, a caesarean section was recommended for the patient's subsequent pregnancy.
This case underscores the importance of considering labor-induced venous hyperpression in the differential diagnosis of spontaneous orbital subperiosteal hematomas.
