PROCEDURES PERFORMED: CT-guided drainage of abscess

CLINICAL HISTORY:

COMPARISON: No previous study available for comparison.

CT Dose:

SEDATION: Monitored by the IR registered nurse or surrogate, an independent trained observer providing Moderate Sedation with fentanyl.

CONSENT: Following discussion procedure its risks benefits (including bleeding and vessel damage) and alternatives, review of readily available relevant imaging prior to the procedure informed consent was obtained witnessed and documented upon the chart. Standard presurgical timeout confirming patient procedure and when relevant side and site was performed. Any discrepancies were resolved via consultation with appropriate readily available data sources. The patient was prepared and draped in standard sterile fashion.

ANESTHESIA: 1% lidocaine for local anesthesia.

DESCRIPTION OF PROCEDURE: After obtaining informed consent, the patient was prepped and draped in the usual sterile manner in position on the CT table. The CT images were then used to mark the puncture site in the . After applying local anesthesia and making a small incision, a 22-gauge Chiba needle was advanced into the abscess cavity. Aspiration yielded frank pus. Subsequently a microwire was placed through the needle and upsized to an 035 wire utilizing a transitional catheter. Wire positioning was confirmed with CT images and over the wire a new 8-French drainage catheter was advanced into the abscess cavity. The catheter was connected to an accordion bag for continuous drainage. The fluid sample was sent to the laboratory for culture analysis. The patient tolerated the procedure without any immediate complications.

FINDINGS: Successful CT-guided drainage of abscess

IMPRESSION:
