A Rare Case of Radial Arteriovenous Fistula (AVF) Post-Transradial Percutaneous Coronary Intervention.

We report a rare case of radial arteriovenous fistula in a middle-aged person after a successful transradial percutaneous coronary intervention. Early release of manual radial compression was the culprit behind the development of radial arteriovenous fistula. Early surgical repair of the radial arteriovenous fistula resulted in the complete resolution of distal forearm symptoms in the abovementioned patient.

The Closure of Grade 1 Coronary Perforation by the Snowplow Phenomenon.

We report an extremely rare case of spontaneous closure of grade 1 coronary perforation by the snowplow phenomenon during the revascularization of a subtotal occlusion in the left anterior descending coronary artery. Coronary artery perforation is usually a nightmare during coronary intervention in the cardiac catheterization laboratory. While large coronary perforation requires the deployment of a covered stent, small perforations require heparin reversal, prolonged balloon inflation, deployment of small coils, or gel foam closure.
