Insights

Open surgical repair (aorto-bifemoral bypass) for aorto-iliac occlusive disease showed longer time to readmission compared to endovascular repair (covered kissing stent), despite similar overall rates. Costs were higher for endovascular procedures.

Area of Science:

  • Vascular Surgery
  • Cardiovascular Interventions

Background:

  • Aorto-iliac occlusive disease (AIOD) poses significant challenges, necessitating effective treatment strategies.
  • Open surgical repair and endovascular techniques are primary interventions for AIOD.

Purpose of the Study:

  • To compare readmission rates, costs, and time to readmission between aorto-bifemoral bypass (ABF) and covered kissing stent (CKS) for AIOD.
  • To evaluate long-term outcomes beyond ninety days for AIOD treatments.

Main Methods:

  • Retrospective comparison of patients undergoing ABF or CKS for AIOD from May 2008 to February 2018.
  • Analysis of readmission rates, costs (EUR), freedom from generic readmission (FFGR), and freedom from readmission for surgical reasons (FFRS).

Main Results:

  • Similar readmission rates for ABF (16%) and CKS (18%).
  • Prosthesis limb or stent occlusion was the most common readmission cause.
  • Longer time to readmission for ABF (35 months) versus CKS (13.5 months).
  • CKS group exhibited higher cumulative re-hospitalization, ICU stay, and reintervention costs.

Conclusions:

  • While not statistically significant, the CKS group showed a trend towards higher readmissions and costs within 36 months.
  • ABF demonstrated a longer interval before readmission compared to CKS.
  • The findings suggest distinct long-term patterns between open and endovascular AIOD treatments.

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...

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 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...
