Insights

Endovascular therapy (EVT) for infrarenal aortic occlusion shows feasibility and favorable midterm patency. This minimally invasive approach offers promising outcomes for patients with this condition.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Medical Devices

Background:

  • Infrarenal aortic occlusive disease presents significant challenges in patient treatment.
  • Endovascular therapy (EVT) is an evolving treatment modality for complex vascular conditions.

Purpose of the Study:

  • To evaluate the treatment outcomes of endovascular therapy (EVT) in patients diagnosed with infrarenal aortic occlusive disease.
  • To assess the feasibility, safety, and midterm efficacy of EVT for this specific patient cohort.

Main Methods:

  • Retrospective analysis of 11 patients with Trans-Atlantic Inter-Society Consensus II D classification infrarenal aortic occlusion treated between January 2012 and December 2015.
  • Evaluation of procedural success rates, complication profiles, and midterm clinical outcomes following EVT.

Main Results:

  • Technical success rate for EVT was 81.8%.
  • The median length of hospitalization was 2 days, with a procedural time of 118.3 ± 60.9 minutes.
  • A 100% primary patency rate at 2 years was observed, with no requirement for reinterventions; one patient experienced contrast-induced nephropathy, which did not necessitate hemodialysis.

Conclusions:

  • Endovascular therapy presents a feasible treatment option for infrarenal aortic occlusion.
  • The midterm patency rates achieved with EVT in this study are favorable, suggesting its potential as a durable solution.

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.

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...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

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...

Aortic Regurgitation III: Medical Management01:25

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
