[Inadequate configurational stability of a DSA pigtail catheter as a cause of complications. Case report and study of the mechanism].
There have been few descriptions extravasation into the superior vena cava and right atrium during intravenous DSA. This is seen almost exclusively when using straight catheters. The configuration of pigtail DSA catheters should reduce or prevent damage to vessel wall due to extravasation. Following an extravasation into the right atrium, which we ascribed to inadequate stability of the distal end of the pigtail catheter, we carried out in vitro experiments with seven DSA catheters from a variety of manufacturers, using an atrial model. Three of these catheters behaved in a manner that would be liable to produce extravasation.
