Insights

Intravascular ultrasonography (IVUS) aids percutaneous coronary intervention (PCI) for complex chronic total occlusions (CTO). However, IVUS-guided PCI carries a risk of thrombotic occlusion, requiring special precautions during the procedure.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Imaging

Background:

  • Percutaneous coronary intervention (PCI) for stumpless chronic total occlusion (CTO) lesions is challenging due to difficulties in identifying entry points using conventional angiography.
  • Intravascular ultrasonography (IVUS)-guided wiring presents a potential solution for navigating these complex CTO lesions.

Observation:

  • A case of thrombotic occlusion occurred during an IVUS-guided PCI procedure for a stumpless CTO.
  • The exact cause of the thrombosis remains unclear but may be linked to prolonged IVUS catheter use.

Findings:

  • IVUS-guided wiring can facilitate penetration of stumpless CTO lesions.
  • Thrombotic occlusion is a potential complication during IVUS-guided stumpless CTO procedures.

Implications:

  • IVUS-guided techniques offer a promising approach for treating complex CTOs.
  • Clinicians must implement specific precautions to mitigate the risk of thrombus formation during prolonged IVUS procedures.
  • Further research is needed to fully understand and prevent IVUS-related thrombosis in CTO interventions.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

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...
