“…The site of carotid artery relocation has been described to be dorsal (McClymont, 1950; Jha et al., 1961; Bone et al., 1962) or ventral (Graham et al., 1937; Dueck et al., 1982) to the sternocephalic muscle. In performing the three techniques, the former site was chosen because it was found easier to manipulate the artery in the lateral rather than in the ventrolateral side of the neck, especially when the experimental design required the animals to be in a standing position during blood sampling.…”

“…Very satisfactory results with techniques B and C have been reported in small ruminants, the carotid artery being functional for 3 months with technique B (Jha et al., 1961) and for some years with another technique similar to our technique C (Dueck et al., 1982). These techniques have also been used in cattle (McClymont, 1950) and dogs (Dueck et al., 1982) with very satisfactory results (carotid artery functional for up to 18 months). In the present study, in groups B and C, the carotid arteries sustained their patency until retirement of the animals.…”

“…The artery has to be in an accessible and protected location, and its patency must be sustained for a long period of time. For this purpose, surgical techniques for displacement of an artery to a subcutaneous location have been described (Graham et al., 1937; McClymont, 1950; Jha et al., 1961; Bone et al., 1962; Linzell, 1963; Hove, 1981; Dueck et al., 1982).…”

Three surgical techniques for subcutaneous relocation of the carotid artery in small ruminants are compared. A total of 25 sheep and seven goats were used and randomly assigned to three groups. In group A (technique A), the carotid artery was moved subcutaneously and kept there by suturing the tissues on both sides of the jugular vein beneath the relocated artery and the skin above it. In the other two groups the relocated artery was secured into a skin strip (technique B) or a skin fold (technique C). The animals were used for repeated blood sampling over a period of several months. Technique A did not provide good immobilization whilst among the three, technique B provided the least protection of the relocated artery and was the most difficult to perform. It was concluded that technique C was superior to the other two methods in providing better conditions for long-term blood sampling.

“…Translocation of the common carotid artery (CCA) to a subcutaneous position has been described as a method to facilitate repeated arterial blood sampling for physiologic and pharmacologic experimental studies. The procedure has been described in dogs, sheep, goats, horses, and cattle, with the earliest description in cattle having been reported in 1950 . The initial variations of the procedure required extensive dissection and creation of an arterial loop surrounded by a protective tube of skin, which was thought to facilitate repeated sampling .…”

Transposition of the common carotid artery in standing cattle

Objective: To describe a method for permanent transposition of the common carotid artery (CCA) in standing cattle.Study design: Experimental study. Animals: Eight healthy, adult, lactating Holstein-Friesian cows.Methods: Cows were restrained with the head and neck extended by using halters, head catch, and squeeze chute. Surgery was performed under local anesthesia and intravenous sedation. The right CCA was approached through a skin incision dorsal and parallel to the jugular vein. The skin incision was extended through the brachiocephalicus and longus capitus muscles. When the vessel was present, ligation of accessory vessels of the CCA and internal jugular vein was performed to facilitate exposure. The artery was sharply dissected from the carotid sheath and elevated by using Penrose drains. The muscles were closed in two layers, leaving the artery in a subcutaneous position. The incision was protected with a tie-over bandage for 1 week. Sampling from the CCA was initiated approximately 6 weeks after surgery. Results: The CCA was successfully transposed and used for repeated arterial blood sampling in all eight cows. No cows had intraoperative complications or evidence of surgical site infection. One cow had a postoperative suture reaction at the site of a suture used for maintaining the tie-over bandage. All arteries remained patent for use in subsequent studies. Conclusion: Permanent translocation of the CCA was successful in all cows in this study and consistently allowed serial arterial blood sampling. Clinical significance: Common carotid artery translocation is possible without general anesthesia in adult cattle and is useful in studies requiring serial sampling of arterial blood.

“…Blood has been obtained from arterialised capillaries in the ear (Verhoeff & Wierda, 1983), the saphenous artery (Donawick & Baue, 1968), the brachial artery (Fisher, 1956) and the caudal auricular artery (Fisher et al, 1980). For the carotid artery, methods for establishing an external carotid loop in cattle (McClymont, 1950) and for subcutaneous deviation (Butler, 1962) have been described for experimental purposes.…”
