Aneurysm III: Interprofessional Care

10
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...

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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

10
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Aneurysm I: Introduction

14
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...

Acute Coronary Syndrome I: Introduction01:30

Acute Coronary Syndrome I: Introduction

31
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Summary

Stent-assisted embolization is an emergency treatment for wide-neck ruptured brain aneurysms when other methods fail. It is less suitable for patients over 80 years old.

Area of Science:

  • Neurosurgery
  • Interventional Radiology
  • Cerebrovascular Disease

Background:

  • Aneurysms with wide necks pose a challenge for endovascular treatment.
  • Acute rupture necessitates urgent intervention.

Purpose of the Study:

  • To report outcomes of stent-assisted embolization for acutely ruptured wide-neck aneurysms.
  • To identify factors associated with poor clinical outcomes.

Main Methods:

  • Retrospective analysis of 19 patients with acutely ruptured wide-neck aneurysms treated between December 2016 and October 2020.
  • Stent-assisted coil embolization (Neuroform EZ/Atlas) used when balloon-assisted embolization failed or was impossible.

Main Results:

  • Complete obliteration in 2/19 cases; neck remnant in 10, body filling in 7.
  • Good clinical outcome (mRS 0-2) in 8 patients; poor outcome (mRS 4-6) in 11.
  • Age over 80 was the only statistically significant factor for poor outcome.
  • Procedure-related complications occurred in 5 patients (in-stent thrombosis, MCA perforation, stent occlusion, coil fracture).

Conclusions:

  • Stent-assisted coil embolization is a viable emergency option for wide-neck ruptured cerebral aneurysms.
  • Consideration should be given to patient age, particularly those over 80.
