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 The thrombus which originally encases the catheter will pile up at the puncture site as the catheter is withdrawn.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: It is concluded that the copolymer guidewire is markedly less thrombogenic than Teflon-coated guidewires.

TL;DR: Inflow of blood into intra-arterial catheters following injection of contrast medium into the common carotid artery in patients and into the aorta in dogs is investigated.

Percutaneous transfemoral coronary arteriography without systemic anticoagulation--a review of 648 consecutive procedures.
TL;DR: The transient nature of the neurologic deficits and the low mortality suggest that the emboli which occurred in these patients were small, possibly platelet-fibrin accumulations, and it is postulated that with the use of careful technic larger emboli capable of producing myocardial infarction with shock or disabling cerebral vascular accidents can be prevented, even in a training situation.

Management of children with chronic femoral artery obstruction
TL;DR: Chronic obstruction of the femoral artery in children is a complication of diagnostic angiography, cardiac catheterization and umbilical artery catheterized and the indications for operation are claudication, muscle wasting, and shortness of the lower limb.

Thromboembolism associated with pigtail catheters.
TL;DR: In vitro comparison of hydraulic characteristics of polyurethane (Cordis) and polyethylene (Cook) pigtail catheters showed higher flow-pressure transmission through the tip of the Cordis polyure thirdane catheter favoring dislodgment of any existing clot.

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.

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).
