Insights
Routine in-hospital observation after CT-guided biopsies is justified for thoracic procedures due to significant delayed major complications. Observation may be omitted for musculoskeletal interventions, but is individually considered for abdominal interventions.
Area of Science:
- Interventional Radiology
- Medical Imaging
- Patient Safety
Background:
- Current guidelines recommend routine in-hospital observation after computed tomography (CT)-guided interventions.
- The necessity of this observation for all procedures requires further evaluation.
Purpose of the Study:
- To assess the frequency of delayed major complications and hospitalizations following CT-guided biopsies.
- To determine if routine in-hospital observation is justified based on complication rates.
Main Methods:
- Retrospective analysis of 433 outpatients undergoing CT-guided biopsies (thoracic, abdominal, musculoskeletal).
- Complications were graded, and delayed complications were defined as those occurring during in-hospital observation.
- Frequencies of delayed major complications and hospitalizations were calculated for each organ group.
Main Results:
- Delayed major complication rates were 8.2% for thoracic, 0.0% for abdominal, and 0.0% for musculoskeletal interventions.
- Delayed hospitalization rates were 8.8% for thoracic, 1.6% for abdominal, and 0.0% for musculoskeletal interventions.
- Significant differences in complication and hospitalization rates were observed between organ groups (P < 0.001).
Conclusions:
- Routine in-hospital observation is justified for thoracic CT-guided interventions to ensure patient safety.
- Routine observation may be omitted for musculoskeletal interventions due to a lack of delayed complications.
- For abdominal interventions, while no delayed complications occurred, delayed hospitalizations were noted, suggesting observation may be beneficial in a controlled environment.
Background:
After computed tomography (CT)-guided interventions, routine in-hospital observation is recommended by the Cardiovascular and Interventional Radiological Society of Europe.
Purpose:
To evaluate the frequency of delayed major complications or hospitalizations after CT-guided biopsies in patients with initially no or minor complications and to assess whether routine in-hospital observation is justified.
Material And Methods:
This retrospective study included 433 outpatients after CT-guided biopsy of the thoracic (n = 176), abdominal (n = 129), or musculoskeletal (n = 128) region with subsequent in-hospital observation. Complications were graded according to the current Society of Interventional Radiology recommendations and grouped into minor or major. A complication that occurred during in-hospital observation was defined as delayed complication. A delayed major complication was a newly developed major complication or a progression from an initially minor to a major complication. Hospitalization frequencies were evaluated similarly. Occurrence, 95% confidence intervals (CI), and P values for significant differences between the three organ groups were calculated. If delayed major complications were more frequent than 1%, routine in-hospital observation was considered justified.
Results:
Delayed, major complication frequencies were: thoracic, 8.2% (95% CI 4.6-13.4); abdominal, 0.0% (95% CI 0.0-2.9); and musculoskeletal, 0.0% (95% CI 0.0-2.9) (P < 0.001). Delayed hospitalization frequencies were: thoracic, 8.8% (95% CI 5.0-14.2); abdominal, 1.6% (95% CI 0.2-5.6); and musculoskeletal, 0.0% (95% CI 0.0-2.9) (P < 0.001).
Conclusion:
After thoracic interventions, routine observation is considered justified for patient safety whereas routine observation may be omitted after musculoskeletal interventions. In the abdominal group, no delayed complications were observed, but delayed hospitalization occurred. Thus, in-hospital observation could be justified in a safe patient environment, but remains an individual decision.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
