CT-guided insertion of closed-tip catheters for deep-seated tumors is a safe and effective method. This study found minimal bleeding and no nerve injury, with minor catheter-related issues during treatment.

Area of Science:

  • Oncology
  • Medical Imaging
  • Surgical Procedures

Background:

  • Deep-seated and half-deep-seated tumors present challenges for effective treatment delivery.
  • Minimally invasive techniques are crucial for improving patient outcomes and reducing complications.

Purpose of the Study:

  • To evaluate the safety and efficacy of closed-tip catheter insertion guided by computed tomography (CT) for treating deep-seated tumors.
  • To assess the complication rates and technical challenges associated with CT-guided catheter placement.

Main Methods:

  • A retrospective analysis of 141 closed-tip catheters inserted into 95 treatment areas between October 1987 and August 1991.
  • Catheter placement was guided by CT scans, with a focus on pelvic tumors (79 cases).
  • Complications such as bleeding, nerve injury, catheter displacement, and infection were documented.

Main Results:

  • No clinical evidence of bleeding was observed in 139 punctures; only two patients experienced transient blood loss.
  • No nerve injury was reported. Catheter-related issues included 19 losses (13%), five displacements, and eight removals due to infection.
  • Two patients showed inflammatory responses, and one developed acute pancreatitis. No metastasis in invasive tracks was observed.

Conclusions:

  • CT-guided insertion of closed-tip catheters is a safe and well-tolerated method for treating deep-seated tumors.
  • While minor complications occurred, the overall procedure demonstrated a favorable safety profile.
  • Further research may optimize catheter management to minimize treatment-related issues.
