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. 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...

Summary

Percutaneous endovascular repair of thoracic and abdominal aortic aneurysms using stent-grafts is safe and effective. This study shows a low rate of access-related complications with the Perclose closure technique, even with large delivery devices.

Background:

Endovascular repair offers a less invasive alternative to open surgery for aortic pathologies.
Percutaneous access and closure techniques are crucial for minimizing complications in endovascular procedures.

Purpose of the Study:

To evaluate the immediate and midterm outcomes of percutaneous endovascular aortic stent-graft repair.
To assess the safety and efficacy of the Perclose closure technique for large-bore arterial access.

Main Methods:

21 patients with thoracic or abdominal aortic pathology underwent percutaneous stent-graft insertion.
Preprocedural computed tomographic angiography (CTA) assessed arterial anatomy for percutaneous access.
A 'preclose' technique using two Perclose devices was employed for all femoral arteriotomies.
Follow-up included clinical examination and CTA at regular intervals up to 36 months minimum.

Main Results:

Percutaneous closure of femoral arteriotomies was successful in 96.6% of cases.
Technical success rate was high with only one conversion to open surgical repair (3.4%).
No significant late complications or >50% reduction in common femoral artery caliber were observed at the access sites.

Conclusions:

Percutaneous aortic stent-graft insertion is a safe procedure with low access-related complication rates.
The Perclose closure technique is effective for managing large-bore arterial access in endovascular aortic repair.
This approach offers a viable alternative to open surgical repair for suitable patients.
