Thrombectomy with Fogarty's catheter as a treatment of induced jugular thrombophlebitis in horses. Carlos A. Dornbusch II ; Winston B. Nicoletti IV ; Maria J. Mamprim V ; Luiz C. Vulcano V. Thrombosis of jugular vein is a common problem in the equine medicine, implying frequently in fatal outcomes. The diagnosis is relatively simple, based on the clinical findings, angiographics images and ultrasonographycs.
The therapeutic employed to a large extent of the cases is unsatisfactory. The purpose of this study was to evaluate the applicability of the thrombectomy with Fogarty's catheter in horses. This technique is routinely used in medicine, in the reestablishment of the vascular perviousness. In the control group evolution of the thrombophlebitis without any therapeutical intervention was evaluated.
The animals of the treatment group were submitted to the thrombectomy with Fogarty's catheter. General clinical parameters were analyzed at the moment of the preinduction MPRE , induction of thrombosis MTI , and at the 10 th day of thrombosis evolution M The procedure induced thrombophlebitis that completely obstructed a segment of the jugular vein in all animals.
In the animals of the control group, the thrombus totally obstructed the vascular lumen until the end of the period of evaluation, and parotid edema and vascular dilated, cranial to the thrombophlebitis of jugular vein were observed. The treatment group presented all veins pervious in the end of the experiment, with total remission of the clinical signs, confirmed by angiographic and ultrasonographic examinations. So far, it was concluded that the technique of thrombectomy with Fogarty's catheter was effective in removal of the thrombosis obstruction experimentally induced in the jugular vein.

Fogarty embolectomy catheter
Fogarty arterial embolectomy catheter is a device developed in by Dr. Thomas J. Fogarty to remove fresh emboli in the arterial system. The catheter is inserted into the blood vessel through a clot. The balloon is then inflated to extract the clot from the vessel.
