Summary
Outpatient angiography and interventional procedures are generally safe, with a low rate of significant complications. Most complications were minor, such as pain or hematoma, and no deaths occurred.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Patient Safety
Background:
- Outpatient procedures are increasingly common.
- Assessing complication rates is crucial for patient safety and procedural evaluation.
Purpose of the Study:
- To prospectively identify complications and their rates in outpatient angiography and interventional procedures.
- To evaluate the safety profile of ambulatory vascular interventions.
Main Methods:
- Prospective study of 1050 consecutive patients (646 men, 404 women) aged 17-89.
- A total of 1239 procedures were analyzed over a 2-year period (1997-1999).
- Complications were recorded and categorized by procedure type.
Main Results:
- Aorto-femoral angiography (560 cases) had a 22% complication rate (124/560), mostly pain/hematoma.
- Neck/cerebral angiography (206 cases) had a 25% complication rate (51/206), including 2 TIAs and 1 CVA.
- Interventional procedures (197 cases) had a 35% complication rate (68/197), with few requiring active treatment.
- Other procedures (276 cases) had a 24% complication rate (65/276), predominantly pain/hematoma.
- Significant complications occurred in 1.5% of cases (18/1239), including 8 contrast allergies.
- No procedure-related deaths were reported.
Conclusions:
- Outpatient angiography and interventional procedures demonstrate a favorable safety profile.
- The overall rate of significant complications is low, supporting the use of these procedures in an ambulatory setting.
