Sheath detachment during coronary arteriogram
1University of Missouri Hospital and Clinics, Columbia, USA.
Insights
Catheter-sheath separation is a rare complication during angiographic procedures, particularly in patients with significant scarring from lower-extremity amputations. This case highlights the challenges in vascular access for diagnostic imaging in complex trauma patients.
Area of Science:
- Interventional Cardiology
- Vascular Surgery
- Radiology
Background:
- Angiographic procedures require precise vascular access for diagnostic and therapeutic interventions.
- Soft-tissue scarring and anatomical deformity can significantly complicate vascular access.
- Previous trauma, such as blast injuries leading to amputation, can result in extensive scarring.
Observation:
- The case involved a patient with bilateral lower-extremity amputation secondary to blast injuries.
- The patient presented with significant soft-tissue scarring and deformity at potential vascular access sites.
- An attempted coronary arteriogram was complicated by an unusual event.
Findings:
- Catheter-sheath separation occurred during the attempted coronary arteriogram.
- This rare complication underscores the technical difficulties in performing angiography in scarred and deformed tissue.
- The patient's history of blast injuries and amputation was a key factor in the access challenges.
Implications:
- This case highlights the need for specialized techniques and careful planning for angiographic procedures in patients with complex anatomical alterations.
- Understanding rare complications like catheter-sheath separation is crucial for improving patient safety in interventional radiology.
- Further research may be warranted to develop safer vascular access strategies for patients with extensive scarring and deformity.
Abstract:
Angiographic procedures are technically difficult when soft-tissue scarring and deformity are present at the site of vascular access. This case demonstrates the rare complication of catheter-sheath separation during an attempted coronary arteriogram. The patient had deformity and soft-tissue scarring due to bilateral lower-extremity amputation secondary to blast injuries sustained in Vietnam.
