Aneurysm IV: Nursing Management

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 III: Interprofessional Care

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.

Background:

Proximal aortic pathologies require complex surgical interventions.
Effective cannulation strategies are crucial for cardiopulmonary bypass and cerebral perfusion during aortic surgery.

Purpose of the Study:

To evaluate the safety and efficacy of innominate artery cannulation using a side-graft technique.
To assess neurologic outcomes associated with this specific cannulation strategy in proximal aortic surgery.

Main Methods:

A retrospective study of 70 patients undergoing proximal aortic surgery from 2012-2020.
Innominate artery cannulation with a side graft was employed, utilizing hypothermic circulatory arrest and antegrade cerebral perfusion in most cases.

Main Results:

The 30-day mortality rate was 7.1%.
Neurologic complications included one stroke (1.4%) and one temporary deficit (1.4%), with transient confusion/agitation in 11.4% of patients.
No local complications or arterial injuries were reported.

Conclusions:

Innominate artery cannulation with a side graft is a safe and effective approach for proximal aortic surgery.
This technique facilitates adequate cardiopulmonary bypass and antegrade cerebral perfusion.
Satisfactory neurologic outcomes were observed, supporting its use in complex aortic procedures.
