The thermic vascular anastomosis (TVA). A new nonsuture method. I. History, instruments, and microsurgical technique. 1981

E Wintermantel

In order to unite blood vessels in a split second during a total clamping time of less than three minutes a new microsurgical technique has been developed. Heat from a frequency electric current applied to calibrated metal loops unites the cuffs of the vessel ends instead of sutures. As a model for vascular anastomoses the new technique was used in an experiment with 320 rats. Two energy output adjustments of the power source combined with application of fibrin glue on the anastomosis are compared. The new instruments developed for this technique and the operation method are presented with reference to earlier vascular surgical procedures, and the results of patency controls of the anastomoses one day, 10 days, and 30 days postoperatively are listed. Preliminary findings of a long term study are added. This study shows that fully patent anastomoses can be obtained with this technique in much less time than with suturing.

D008866	Microsurgery	The performance of surgical procedures with the aid of a microscope.
D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.

D002339	Carotid Arteries	Either of the two principal arteries on both sides of the neck that supply blood to the head and neck; each divides into two branches, the internal carotid artery and the external carotid artery.	Arteries, Carotid,Artery, Carotid,Carotid Artery
D004564	Electrocoagulation	Procedures using an electrically heated wire or scalpel to treat hemorrhage (e.g., bleeding ulcers) and to ablate tumors, mucosal lesions, and refractory arrhythmias. It is different from ELECTROSURGERY which is used more for cutting tissue than destroying and in which the patient is part of the electric circuit.

D005339	Fibrin Foam	A dry artificial sterile sponge of fibrin prepared by clotting with thrombin a foam or solution of fibrinogen. It is used in conjunction with thrombin as a hemostatic in surgery at sites where bleeding cannot be controlled by more common methods.
