Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

746
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

  • To review the general principles and technical details of preoperative embolization for hypervascular head, neck, and spinal tumors.
  • To discuss indications, treatment goals, techniques, outcomes, and potential complications.
  • To provide illustrative case examples for enhanced understanding.

Main Methods:

  • Review of contemporary neuroendovascular practice.
  • Discussion of established and emerging embolization techniques.
  • Analysis of treatment outcomes and complication profiles.

Main Results:

  • Preoperative embolization is a valuable tool for reducing tumor vascularity and facilitating surgical resection.
  • Specific techniques vary depending on tumor location and vascular supply.
  • Careful patient selection and procedural planning are crucial for optimizing outcomes and minimizing risks.

Conclusions:

  • Preoperative embolization is an integral part of the multidisciplinary management of hypervascular head, neck, and spinal tumors.
