Summary

Computed tomography (CT) can visualize hematomas after transfemoral catheterization. A new classification system categorizes these iatrogenic hematomas into four types based on bleeding location and spread, aiding clinical management.

Area of Science:

  • Radiology
  • Vascular Surgery
  • Medical Imaging

Background:

  • Hematomas are uncommon complications of transfemoral catheterization.
  • Computed tomography (CT) findings of these hematomas are rarely documented.

Purpose of the Study:

  • To develop a classification system for CT-detected iatrogenic hematomas following transfemoral catheterization.
  • To correlate hematoma type with anatomical location and bleeding patterns.

Main Methods:

  • Review of CT scans in patients with post-catheterization hematomas.
  • Development of a classification system based on the anatomical site and spread of bleeding.
  • Categorization into four types: retroperitoneal, intraperitoneal, groin/thigh, and abdominal wall.

Main Results:

  • A four-type classification system for iatrogenic hematomas was devised.
  • Hematoma type is influenced by fascial plane spread and proximity to the femoral sheath/triangle.
  • The four identified types are retroperitoneal, intraperitoneal, groin and thigh, and abdominal wall hematomas.

Conclusions:

  • A novel CT-based classification system for transfemoral catheterization-related hematomas has been established.
  • Recognizing these four distinct hematoma types is crucial for understanding their clinical significance and guiding patient care.
