Aneurysm III: Interprofessional Care

41
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...

Venous Thrombosis III: Interprofessional Care

42
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

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...

Summary

Thoracic endovascular aortic repair (TEVAR) significantly reduces mortality in blunt aortic injury (BAI) patients. Delayed TEVAR with heparin is safe, even with traumatic brain injury (TBI), improving survival without affecting neurologic function.

Area of Science:

  • Trauma Surgery
  • Cardiovascular Surgery
  • Neurosurgery

Background:

  • Blunt aortic injury (BAI) and traumatic brain injury (TBI) are leading causes of death in blunt trauma patients.
  • Identifying mortality predictors and the impact of interventions is crucial for improving outcomes.

Purpose of the Study:

  • To identify predictors of mortality in patients with BAI.
  • To evaluate the effect of procedural heparinization during TEVAR on neurologic outcomes in BAI patients, particularly those with concomitant TBI.

Main Methods:

  • Retrospective analysis of BAI patients over 8 years.
  • Comparison of demographics, injury severity, time to TEVAR, morbidity, and mortality.
  • Multivariable logistic regression and Youden's index to determine mortality predictors and optimal TEVAR timing.

Main Results:

  • 129 BAI patients identified; 20% had TBI.
  • BAI/TBI patients had higher injury severity, lower GCS, and increased mortality.
  • TEVAR was the sole modifiable factor reducing mortality (OR 0.11, P=0.002).
  • Optimal time to TEVAR was 14.8 hours; delayed TEVAR showed improved survival.
  • Procedural heparinization during TEVAR was safe in TBI patients, with no neurologic decline.

Conclusions:

  • TEVAR is the only modifiable predictor of reduced mortality in BAI.
  • Delayed TEVAR with heparin is a safe and effective strategy for BAI patients, including those with TBI.
  • This approach improves survival without compromising neurologic function at discharge.
