Aneurysm IV: Nursing Management01:22

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
Aneurysm I: Introduction01:30

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

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...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Aneurysm III: Interprofessional Care01:26

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Summary
This summary is machine-generated.

Iatrogenic aneurysms after craniotomy are very rare, with only a few cases documented. This study reports a case of a traumatic aneurysm developing during dural closure, emphasizing the risk of arterial injury during the procedure.

Area of Science:

  • Neurosurgery
  • Vascular Surgery
  • Neurology

Background:

  • Craniotomies are common neurosurgical procedures performed globally.
  • Iatrogenic aneurysms are exceptionally rare complications following craniotomy.
  • Existing literature primarily consists of anecdotal reports.

Observation:

  • A case of an iatrogenic aneurysm affecting a cortical vessel is presented.
  • The aneurysm likely developed during the dural closure phase of a conventional craniotomy.
  • It was incidentally discovered six months post-surgery during a routine control angiography.

Findings:

  • The patient underwent successful treatment via parent vessel trapping and aneurysm excision.
  • Histopathological examination confirmed the aneurysm as a true traumatic type.
  • This case underscores the potential for arterial injury during craniotomy.

Implications:

  • Highlights a rare but significant risk associated with craniotomy procedures.
  • Emphasizes the importance of meticulous surgical technique, especially during dural closure.
  • Suggests vigilance for delayed complications such as iatrogenic aneurysms in post-craniotomy patients.
