“…However, the origins and variations of the VA have been observed in the guinea pig, rabbit and hare. [12][13][14] In these studies, the VA entered into the transverse foramen of the C6 in all cases; the authors did not find any malformation of the cervical vertebrae. The study of Chavangvongsanugool et al, 15 observing 58 dogs, showed that the branching patterns of the SA were breed specific.…”

The vertebral arteries, as the first branches from the subclavian arteries, normally enter into the transverse foramen of the sixth cervical vertebra in dogs. This case report presents the non‐standard course of the left vertebral artery and unilateral asymmetry of the sixth cervical vertebra in a 14‐year‐old female mixed breed dog. The anomaly was an incidental finding during the preparation of a corrosion cast prepared for educational and scientific purposes. The left sixth cervical vertebra transverse foramen and the ventral lamina were not developed. The left vertebral artery originated normally from the left subclavian artery, but atypically entered into the transverse foramen of the fifth cervical vertebra. On the right side, the anatomical structures of the sixth cervical vertebra and the course of the right vertebral artery were normally developed. To our knowledge, this is the first case of such an anomaly described in a dog.

“…The variability of the vertebral arteries at the place of origin was studied in laboratory animals and dogs. The course of both vertebral arteries was standard, and they entered into the sixth cervical vertebra and pierced the transverse foramen in all subjects studied [4,5,9,12,13,15]. P o l s et al [15] characterised the branching patterns to the I -scale in dogs.…”

The spinal cord issues affect dogs and cats very commonly. The right diagnostics, therapy, and patient’s managements are challenging for almost all veterinarians. There exist many vascular anomalies such as: the vertebral arteries ectasia, hypoplasia and subclavian steal syndrome. These anomalies affect the patient’s neurological status directly. The modern diagnostic approaches (Computed Tomography [CT], and Magnetic Resonance Imaging [MRI]) help with the diagnosis of the vascular abnormalities of the spinal cord and various other vascular anomalies. The cervical part of the spinal cord is supplied with the spinal branches from the vertebral arteries. The vertebral arteries as the first branches arise separately from the subclavian artery and they exit the thoracic aperture and enter into the transverse foramen of the sixth cervical vertebra. The arterial system of dogs was studied in 14 dogs (carcasses), the average age of which was 7 years. The carcasses were divided into two groups: 11 dogs were studied by the corrosion casting method (Duracryl Plus) and 3 dogs were studied by contrast radiography (Urografin 76 %). We confirmed the standard origin and course of the left vertebral for all but one case. The right vertebral artery originated as an independent branch in 57.14 % of the cases; in the rest of them, we reported on the variability in origin and formation of inconstant branches. The formation of anastomoses was reported also. Our work contributed new information about the thoracic and cervical arterial system in dogs.

“…Based on the lateral thoracic artery technique described by Delaere, our aim was to make a flap from the internal thoracic artery. In rabbits, the latter arises from the subclavian artery, runs ventrocaudally parallel to the sternum, and sends perforating branches to the chest wall, constituting the main vascular supply of the mammary glands 19 . The primary aim of adapting this technique is to obtain a bilateral pediculated flap (with both arterial and venous components) through a longitudinal centrothoracic wound, where each one of them will be able to wrap a different construct.…”

Decellularized tracheal prelamination implant: A proposed bilateral double organ technique

In tracheal replacement transplantation, prelamination is a critical stage. Nowadays, the most widely used prelamination technique is the prethoracic fascia flap with lateral thoracic artery. We propose a flap based on the internal thoracic artery, which allows a relatively non‐aggressive double organ implant, and we have tested its efficacy in decellularized tracheas. Tracheas of albino New Zealand rabbits were decellularized following a protocol that uses detergents and cryogenization, sterilized with 1kGy gamma radiation, and tutorized with a stent. Bilateral pedicled flaps made of pectoral fascia and a muscular component were harvested through a longitudinal 3‐cm central thoracic incision, wrapping the tracheas with them in 16 rabbits, remaining them implanted for 2, 4, 8, and 12 weeks. The tracheas were then studied histologically using standard stainings plus immunohistochemistry (CD31). The models were adjusted with Bayesian statistics using ordinal regression; results as odds ratios and credibility intervals. All analysis were performed using R software. Acute inflammatory cell invasion was observed at 2 weeks, which almost disappeared at week 8 after implant. Only macrophages and giant cells increased between Weeks 8 and 12 (OR 10.487, CI [1.603‐97.327]). The cartilage maintained its structure, with slight signs of ischemia in a few cases. New CD31‐positive vessels were observed from Week 2 and increasing thereafter, reaching a maximum peak at Week 8. We propose a bilateral implant technique that is viable and effective as a prelamination option for two concurrent tracheas, achieving perfect vascularization and integration of the organ with hardly any inflammatory response in the medium or long term.
