procedural success
Achievement of predefined technical and clinical endpoints during endovascular intervention without major complications.
Full Definition
Procedural success in angiology represents the successful completion of an endovascular intervention meeting predefined technical criteria without major periprocedural complications. Technical success typically requires achievement of less than 30% residual stenosis, restoration of antegrade flow, and successful device deployment without vessel perforation, dissection, or acute closure. Clinical success additionally encompasses symptomatic improvement and freedom from target vessel revascularization during the immediate postprocedural period. Success criteria may vary by procedure type, vessel location, and patient factors. Documentation should specify both technical parameters achieved and absence of complications. Failed procedures require detailed explanation of factors preventing success and plans for alternative treatment approaches.
Usage
Usage note: Define specific success criteria and document achievement of technical endpoints in procedural reports.
