Clinical Scorecard: Development of Innovative Embolization Materials and Assessment of Their Efficacy in Preventing Type II Endoleak After Endovascular Aneurysm Repair for Abdominal Aortic Aneurysm

At a Glance

CategoryDetail
ConditionType II Endoleak (T2EL) after Endovascular Aneurysm Repair (EVAR) for Abdominal Aortic Aneurysm (AAA)
Key MechanismsThrombin-Coated Controllable Coil (TCC) enhances thrombosis and prevents T2EL.
Target PopulationPatients undergoing EVAR for AAA, particularly those at risk for T2EL.
Care SettingEndovascular surgical procedures.

Key Highlights

  • TCC significantly shortened coagulation time compared to IDC and control groups.
  • TCC achieved complete thrombosis within the aneurysm without complications.
  • In vitro, TCC promoted apoptosis of vascular smooth muscle cells (VSMCs) and inhibited their proliferation.
  • Transcriptomic analysis revealed 161 differentially expressed genes associated with TCC treatment.

Guideline-Based Recommendations

Diagnosis

  • Monitor for Type II Endoleak (T2EL) post-EVAR using imaging protocols.

Management

  • Consider prophylactic embolization of the aneurysm sac or side branches during EVAR.

Monitoring & Follow-up

  • Follow up on aneurysm sac size and T2EL status at regular intervals.

Risks

  • Persistent T2EL can lead to aneurysm sac enlargement and increased risk of reoperation.

Patient & Prescribing Data

Patients with abdominal aortic aneurysm undergoing EVAR.

TCC shows promise as a next-generation embolic material for preventing T2EL.

Clinical Best Practices

  • Utilize TCC for enhanced control and efficacy in preventing T2EL during EVAR.
  • Regularly assess patients for signs of T2EL and aneurysm sac changes post-procedure.
