Insights

A rare internal maxillary artery pseudoaneurysm after endoscopic sinus surgery was successfully treated with endovascular embolization. This minimally invasive approach prevented rupture and complications, offering a viable treatment for this uncommon condition.

Area of Science:

  • Vascular Surgery
  • Endoscopic Sinus Surgery
  • Interventional Radiology

Background:

  • Pseudoaneurysms are vascular defects lacking true arterial walls, posing a rupture risk.
  • Pseudoaneurysms following endoscopic sinus surgery are exceptionally rare, with only four cases previously reported.
  • The internal maxillary artery is a potential, though infrequent, site for post-surgical pseudoaneurysm formation.

Observation:

  • A pseudoaneurysm in the internal maxillary artery was identified after endoscopic sinus surgery.
  • The patient presented with a condition requiring immediate and effective intervention.

Findings:

  • The pseudoaneurysm was successfully managed using endovascular embolization.
  • No bleeding or complications were observed six months post-embolization, indicating a favorable outcome.

Implications:

  • Endovascular embolization is an effective treatment for internal maxillary artery pseudoaneurysms post-endoscopic sinus surgery.
  • This case expands the understanding of rare complications associated with endoscopic sinus procedures.
  • Prompt intervention with embolization can prevent serious hemorrhage and ensure patient safety.

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...

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...

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...

Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
