Insights

A 77-year-old woman experienced chest discomfort and underwent coronary angiography (CAG). During angioplasty and stenting, the intravascular ultrasonography (IVUS) catheter became entrapped, necessitating emergency bypass surgery.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Imaging
  • Vascular Surgery

Background:

  • Coronary angiography (CAG) is a key diagnostic tool for coronary artery disease.
  • Percutaneous coronary intervention (PCI) with stenting is a common treatment for diseased coronary vessels.
  • Intravascular ultrasonography (IVUS) provides detailed imaging during PCI procedures.

Observation:

  • A 77-year-old female patient presented with chest discomfort.
  • CAG revealed two diseased coronary vessels, treated with angioplasty and stenting.
  • During post-stent IVUS, the catheter became entrapped in the left anterior descending artery.

Findings:

  • Entrapment of the IVUS catheter led to acute ischemia of the anterolateral wall.
  • Electrocardiogram (ECG) changes confirmed the ischemic event.
  • The patient required immediate surgical intervention.

Implications:

  • This case highlights a rare but serious complication of IVUS-guided PCI.
  • Emergency coronary artery bypass grafting (CABG) was successfully performed for catheter removal and revascularization.
  • Careful technique and awareness of potential IVUS complications are crucial in interventional cardiology.

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...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
