The common marmoset (Callithrix jacchus) are small primates belonging to the family Cebidae, subfamily Callitrichinae and are the most well-known and common in adaptation to captivity. The scarcity of data in the literature on the anatomy of these marmosets and wild animals hinders the application of appropriate anesthetic and surgical procedures and therapeutics. In order to understand the anatomic variations in the lobation and bronchopulmonary segmentation the lungs were dissected from nine adult common marmoset (Callithrix jacchus) corpses, five males and four females. In the marmosets, the right lung presented cranial lobe, middle lobe, caudal lobe and accessory lobe while the left lung presented cranial and caudal lobes. The fissures were very pro-eminent in both the lungs. The main right bronchus emitted independent branches, one for each lobe, and it followed in a straight line in the caudal lobe as a continuation of this bronchus and the same was observed in the main left bronchus. The bronchopulmonary segmentation in the right lung ranged from one to five branches in the cranial lobe; the middle lobe had a single branch; the caudal lobe had three to five branches and the accessory lobe had three branches. In the left lung the cranial lobe bronchopulmonary segmentation ranged from one to five branches while in the caudal lobe it was three to four branches.

RESUMO.As aves da ordem Psittaciformes estão entre as mais criadas como pet, o que consequentemente aumenta a procura por atendimento médico veterinário especializado em aves e, para tal, o estudo e conhecimento da anatomia destes animais se torna essencial. De outra forma, a morfologia craniana é fundamental na identificação de espécie de animais com características morfológicas externas semelhantes. Buscou-se obter dados referentes ao crânio de Diopsittaca nobilis, para contribuir com o conhecimento anatômico desta espécie. O presente estudo foi realizado com 3 crânios de Diopsittaca nobilis, que foram preparados através de dissecação e maceração controlada com água. Apesar do processo natural de fusão, puderam ser identificados ossos e estruturas do crânio com suas particularidades. Realizou-se também mensurações dos crânios, onde a média da largura máxima do crânio foi de 28,70mm e do comprimento do crânio sem a ranfoteca foi de 36,16mm. Os dados obtidos contribuem para a melhor caracterização da espécie.Palavras chave: Anatomia, psittacidae, crânio Anatomical and morphometric aspects of the Diopsittaca nobilis Linnaeus, 1758ABSTRACT. The birds of the order Psittaciformes are among the most created as pet, which consequently increases the demand for specialized veterinary care in birds and, for this, the study and knowledge of the anatomy of these animals becomes essential. Otherwise, cranial morphology is fundamental in the identification of species of animals with similar external morphological characteristics. We sought to obtain data regarding the skull of Diopsittaca nobilis, to contribute with the anatomical knowledge of this species. The present study was performed with 3 skulls of Diopsittaca nobilis, which were prepared by dissection and controlled maceration with water. Despite the natural process of fusion, bones and structures of the skull could be identified with their particularities. Measurements were also made of the skulls, where the mean maximum width of the skull was 28.70mm and the length of the skull without the ranogram was 36.16mm. The data obtained contribute to the better characterization of the species.

Background The objective of the present study was to study the anatomy of the respiratory system of Sapajus libidinosus. Methods Ten corpses of adult animals were used. To analyze the bronchial tree, transparent acetic silicone was injected and then dissected. Results The trachea presented a mean of 32 rings. These spaces were delimited for tracheostomy and tracheotomy between the 1st and 3rd ring or between the 9th and 11th ring, and for thoracocentesis at the 7th or 8th intercostal space. For tracheostomy and tracheotomy, the best access point was in the ventral region of the neck and transverse incision of the rings. For thoracocentesis, cranioventral insertion of the catheter is recommended in the 8th intercostal space. Conclusions The trachea and lung anatomy applied to clinical and surgical procedures the robust capuchin monkey is similar to both wild and domestic carnivores.

The persistence of the fourth right aortic arch (PRAA) is a congenital malformation that affects the heart base’s main vessels. Surgical treatment is recommended and should be advocated as a matter of urgency. In this context, efficient anesthesia planning is necessary, with satisfactory analgesia, associating multimodal techniques with regional blocks. The present work aims to report the anesthetic procedure during corrective surgery for PRAA in a dog. Neuroleptanalgesia was intramuscularly performed, using acepromazine (0.015 mg.kg-1) and methadone (0.3 mg.kg-1) in pre-anesthetic medication. Ketamine (1 mg.kg-1) and propofol (3 mg.kg-1) were administered at induction, both intravenously, followed by maintenance using total intravenous anesthesia with propofol (initial rate of 0.4 mg.kg-1 .minute) and remifentanil, (0.2 mcg.kg.-1.minute). In addition, ultrasound-guided regional intercostal block was performed, with 5% bupivacaine without vasoconstrictor (0.05ml.kg-1). Ketamine infusion was postoperatively maintained for one hour. The instituted protocol proved to be satisfactory in controlling trans and postoperative pain, maintaining all parameters stable during and after the procedure, without any intercurrence. Thus, the protocol provided quality recovery to the patient.
