Summary
Renal artery spasm during angioplasty can cause serious issues, especially in young patients with fibromuscular dysplasia. Pre-angioplasty administration of medications like tolazoline, lidocaine, nitrates, or calcium blockers can reduce spasm incidence and severity.
Area of Science:
- Interventional Cardiology
- Vascular Medicine
- Nephrology
Background:
- Renal artery spasm is a known complication of transluminal angioplasty.
- This complication can lead to severe consequences, particularly in young individuals with fibromuscular dysplasia.
Purpose of the Study:
- To report the authors' experience with renal artery spasm during angioplasty.
- To evaluate methods for decreasing the incidence and severity of renal artery spasm.
Main Methods:
- The study involved 98 cases (105 renal arteries).
- Medications including tolazoline, lidocaine, nitrates, and calcium blockers were administered.
- Administration was either directly into the renal artery or systemically prior to angioplasty.
Main Results:
- The authors present their experience in managing renal artery spasm.
- Specific pharmacological interventions were employed to mitigate spasm during the procedure.
Conclusions:
- Pre-angioplasty administration of tolazoline, lidocaine, nitrates, or calcium blockers is recommended.
- These interventions aim to decrease the occurrence and intensity of renal artery spasm.
