Arterial Thrombus Formation During Clinical Percutaneous Catheterization
TLDR
Deposition of thrombotic material on catheters was observed following more than 50% of 93 diagnostic catheterizations and a definite time relationship between the thrombus formation and the duration of the catheterization procedure was noted.Abstract:
Deposition of thrombotic material on catheters was observed following more than 50% of 93 diagnostic catheterizations. The incidence of deposition of thrombotic material on catheters remaining in the body for more than 1 day was 100%. Polyethylene and siliconized polyurethane catheters were less thrombogenic than Teflon end-occluded catheters. A definite time relationship between the thrombus formation and the duration of the catheterization procedure was noted. The growth of thrombi on the outside of catheters does not appear to be linear since catheters can remain in place for 10 days or more. Postcatheterization thrombosis is believed to be due to thrombi stripped from the catheter by the arterial wall. The thrombus which originally encases the catheter will pile up at the puncture site as the catheter is withdrawn. The thrombus may remain attached at the puncture site or embolize peripherally.read more

TL;DR: Hydrophilic microcatheters and guiding catheters are less thrombogenic than their nonhydrophilic counterparts, but not all hydrophilic coatings are equally hypothrombogenicity.

Attempts to reduce arterial thrombosis after cardiac catheterization in children: Use of percutaneous technique and aspirin
Michael D. Freed,Michael D. Freed,Amnon Rosenthal,Amnon Rosenthal,Donald C. Fyler,Donald C. Fyler +5 more
TL;DR: Percutaneous catheterization was associated with a significantly fewer number of diminished pulses and the use of an antiplatelet agent, aspirin, would reduce the incidence of arterial thrombosis after cardiac catheterized children.

TL;DR: Advantages of percutaneous sheath cardiac catheterization include the ability to use the same vessel for repeat studies, the small incidence of arterial complications, the ease of making many changes in catheter as well as the able to use any type of catheter.

TL;DR: In an attempt to decrease friction between polymers commonly used as catheter materials, oxidation of polyethylene, fluorinated ethylene-propylene copolymer, poly(vinyl chloride), silicone rubber, and polystyrene surfaces was induced by exposing the polymers to radio frequency glow discharge (RFGD) in a helium environment.

TL;DR: This study was devised to assess the role of several factors in the production of local arterial thrombosis, including type of catheter, duration of procedure, and oscillometric index of the limb employed.

TL;DR: The purpose of this work was to investigate the rate of clotting on the surface of various catheters and to find possible means of prevention.

Platelet adhesion and throms formation on vascular catheters in dogs.
TL;DR: It was thought worthwhile to investigate if platelets adhere to the surface of a catheter and aggregate, as there is evidence that the risk varies with the area of the outer surface of the intravascular part of the catheter.

TL;DR: VASCULAR catheterization is widely employed in diagnostic technics (angiography' sampling of blood, and recording of blood pressure) and therapeutic methods (implants of artificial pacemakers and intravenous and intra–arterial drip infusions).
