Aneurysm IV: Nursing Management

621
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 II: Clinical Manifestations and Diagnostic Studies

589
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...

Aneurysm III: Interprofessional Care

478
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

Acute subdural hematoma after thoracic aortic surgery is linked to intraoperative platelet transfusions. Careful platelet administration and potentially avoiding retrograde cerebral perfusion may reduce risks.

Area of Science:

  • Neurosurgery
  • Cardiovascular Surgery
  • Hematology

Background:

  • Acute subdural hematoma (ASH) is a rare but serious complication following open-heart surgery.
  • ASH can significantly increase patient mortality and morbidity.

Purpose of the Study:

  • To evaluate the incidence of postoperative acute subdural hematoma (ASH) in patients undergoing thoracic aortic surgery.
  • To identify risk factors associated with ASH in this patient population.

Main Methods:

  • Retrospective analysis of 53 patients who underwent thoracic aortic repair with open distal anastomosis from 2009-2013.
  • Patients were divided into ASH and non-ASH groups for comparison.
  • Variables analyzed included cerebral perfusion parameters and intraoperative platelet transfusion volume.

Main Results:

  • Eight patients (15.1%) developed transient symptomatic ASH, none requiring surgical intervention.
  • Significant differences were observed in retrograde cerebral perfusion flow and intraoperative platelet transfusion volume between groups.
  • Multivariate analysis identified intraoperative platelet transfusion as a significant risk factor for ASH (OR=0.9, CI: 0.81-0.98, p=0.015).

Conclusions:

  • The study suggests that appropriate platelet transfusion management is crucial.
  • Findings indicate a potential benefit in regulating flow or avoiding retrograde cerebral perfusion to minimize ASH risk.
