Insights

Sonographically guided subclavian vein puncture improves success rates and significantly reduces complications for long-term central venous access device placement, such as Hickman catheters.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Vascular Access

Background:

  • Central venous catheters are crucial for long-term venous access, particularly for chemotherapy.
  • Traditional blind subclavian vein puncture carries risks like pneumothorax and arterial puncture.
  • Minimizing procedural complications is essential for patient safety and effective treatment.

Purpose of the Study:

  • To evaluate the efficacy and safety of sonographically guided subclavian vein puncture for central venous catheter placement.
  • To compare complication rates between sonographically guided and blind puncture techniques.
  • To determine if ultrasound guidance enhances success and reduces risks in Hickman catheter insertion.

Main Methods:

  • A comparative study involving 80 patients undergoing subclavian vein catheterization for long-term venous access.
  • Group 1: 40 sonographically guided punctures; Group 2: 40 blind percutaneous punctures.
  • Both groups underwent fluoroscopically controlled catheter placement; complication rates were meticulously recorded.

Main Results:

  • Sonographically guided puncture achieved a 100% success rate, compared to 95% with blind puncture.
  • Puncture-related complications were significantly lower in the sonographically guided group (0%) versus the blind group (10%).
  • Specific complications like pneumothorax and hemothorax were exclusively observed in the blind puncture group.

Conclusions:

  • Sonographically guided subclavian vein puncture is a superior technique for placing indwelling central venous catheters.
  • Ultrasound guidance enhances procedural success and substantially decreases the incidence of puncture-related complications.
  • This method offers a safer alternative for establishing long-term venous access, especially for patients with hematologic malignancies requiring chemotherapy.
