    Abstract:

    RESUMO Este estudo objetivou descrever a lobacao pulmonar e a distribuicao bronquica da jaritataca. Foram utilizados quatro especimes provenientes de atropelamentos. Os animais exibiram pulmoes em forma de semicone e os lobos cranial, medio, caudal e acessorio formaram o pulmao direito. O pulmao esquerdo exibiu lobos cranial e caudal, sem divisao do lobo cranial. O bronquio principal direito se trifurcou em um bronquio para o lobo cranial, um para o medio e um para os lobos caudal e acessorio. O bronquio Lobar cranial direito se dividiu em tres bronquios segmentares; o bronquio Lobar acessorio e o Lobar medio direito originaram dois bronquios segmentares; o bronquio Lobar caudal direito deu origem a seis bronquios segmentares. O bronquio principal esquerdo bifurcou-se em um bronquio para o lobo cranial e um para o lobo caudal. O bronquio Lobar cranial esquerdo dividiu-se em seis bronquios segmentares, assim como o bronquio Lobar caudal esquerdo. A distribuicao bronquica e a lobacao dos pulmoes da jaritataca sao diferentes das reportadas em carnivoros domesticos e roedores selvagens. Palavras-chave: pulmao, lobacao, bronquio, Conepatus semistriatus LUNG LOBATION AND BRONCHIAL DISTRIBUTION IN THE STRIPED HOG-NOSED SKUNK ( Conepatus semistriatus, Boddaert, 1785) – SHORT COMMUNICATION ABSTRACT This study aimed to anatomically describe the lung lobation and bronchial distribution in the striped hog-nosed skunk. Lungs of four animals which were run over were used. Animals presented semicone-shaped lungs and the right lung was constituted by cranial, middle, caudal and accessory lobes. The left lung presented cranial and caudal lobes, and no cranial lobe division was noted. The right main Bronchus divided into one Bronchus to the cranial lobe, one to the middle lobe and one to the caudal and accessory lobes. The right cranial Lobar Bronchus divided into three segmental bronchi; the accessory Lobar Bronchus and the right middle Lobar Bronchus gave origin to two segmental bronchi; the right caudal Lobar Bronchus originated six segmental bronchi. The left main Bronchus bifurcated into a Bronchus to the cranial and a Bronchus to the left caudal lobes. The left cranial Lobar Bronchus divided into six segmental Bronchus, as well as the left caudal Bronchus. The bronchial distribution and the lung lobation in the striped hog-nosed skunk are different from the ones reported in domestic carnivorous and wild rodents.

Fueron empleados cuatro especimenes provenientes de atropellamientos. Los animales exhibieron pulmones en forma casi conica y el pulmon derecho estaba formado por lobulos craneal, medio, caudal y accesorio. El pulmon izquierdo exhibio lobulos craneal y caudal, pero sin division del lobulo craneal. El bronquio principal derecho se trifurco en un bronquio para el lobulo craneal, uno para el medio, y uno para los lobulos caudal y accesorio . El bronquio lobular craneal derecho se dividio en tres bronquios segmentares; el bronquio lobular accesorio y el lobular medio derecho originaron dos bronquios segmentares; ya el bronquio lobular caudal derecho dio origen a seis bronquios segmentares. El bronquio principal izquierdo se bifurco en un bronquio para el lobulo craneal y uno para el lobulo caudal. El bronquio lobular craneal izquierdo se dividio en seis bronquios segmentares, asi como el bronquio lobular caudal izquierdo. La distribucion de bronquios y de lobulos pulmonares de la mofeta es diferente de la reportada en la literatura para carnivoros domesticos y roedores salvajes.

  • lobacao pulmonar e distribuicao bronquica do ourico cacheiro sphiggurus villosus lung lobation and bronchial distribution of the orange spined hairy dwarf porcupine sphiggurus villosus
    2012
    Co-Authors: Gregorio Correa Guimaraes, Gabriela Castro Lopes, Britto Rosa, Fabricio Singaretti De Oliveira
    Abstract:

    Background: The orange-spined hairy dwarf porcupine (Sphiggurus villosus) is a mammal found in Brazil, Venezuela, Guyanas and Bolivia. Its dorsum is yellowish brown and presents a great number of spines. There are no spines in the belly area, which is covered with softer fur. It can host ticks and louses, hemoparasites and endoparasites. This paper aimed to describe the lung lobation and the bronchial distribution of the orange-spined hairy dwarf porcupine. Materials, Methods & Results: The lungs of two orange-spined hairy dwarf porcupines, ran over by cars and with no damage in the viscerae, were used in the study. Animals were set with intramuscular and intravisceral injections of a 10% formaldehyde solution and further dissected. The right lung was bigger than the left one and presented cranial, middle, caudal and accessory lobes, and the cranial lobe was bilobated in cranial and caudal portions. The left lung presented cranial and caudal lobes, and the former was subdivided into cranial and caudal portions. The right main Bronchus divided into three bronchi, one to the cranial, one to the middle and one to the caudal and accessory lobes. The right Lobar Bronchus gave origin to five segmental bronchi to the cranial portion and three segmental bronchi to the caudal portion; the middle Lobar Bronchus originated four segmental bronchi; the accessory lobe Bronchus was originated from the right caudal lobe and divided into two segmental bronchi. The right Lobar Bronchus divided into eleven segmental bronchi. The main left Bronchus bifurcated into one Bronchus to the cranial lobe and one to the caudal lobe; the left cranial lobe Bronchus divided into five to the cranial portion and two to the caudal portion; the left caudal lobe Bronchus originated eleven segmental bronchi as well as the right one. Discussion: Markable interLobar fissures were noticed between lobes, similarly to the domestic carnivorous, to the crabeating raccoon (Procyon cancrivorus) and to wild rodents as agoutis (Dasyprocta azarae). There was a left lobe division, differently from the described in the crab-eating raccoon and horses, and similarly to the described in domestic carnivorous or in agoutis, capybaras (Hydrochoerus hydrochaeris) and pacas (Agouti paca). In all lobes, but the accessory lobe, Lobar bronchi divided into several segmental bronchi, differently from the described in the right cranial and accessory lobes of the domestic carnivorous and of the crab-eating raccoon, and from the right middle lobe Bronchus of the paca, which presented a bifurcated Lobar Bronchus. It also differed from the left cranial lobe of agoutis and pacas, which presented one or three segmental bronchi to this lobe, respectively. In the accessory lobe, there was a Lobar Bronchus bifurcating in segmental bronchi, as described in the domestic carnivorous and in the crab-eating raccoon. The bronchial distribution and lung lobation of the orange-spined hairy dwarf porcupine were different from the ones reported in domestic carnivorous and horses, wild rodents and from the crab-eating raccoon, with a markable division in the left and right cranial lobes, as in the domestic ruminants, from whom it differed due the absence of the tracheal Bronchus.

  • reverse v shape kinking of the left lower Lobar Bronchus after a left upper lobectomy and its surgical correction
    The Korean Journal of Thoracic and Cardiovascular Surgery, 2014
    Co-Authors: Minseok Kim, Yoo Hwa Hwang, Hye Seon Kim, In Kyu Park, Chang Hyun Kang, Young Tae Kim
    Abstract:

    A 76-year-old male underwent a left upper lobectomy with wedge resection of the superior segment of the left lower lobe using video-assisted thoracoscopic surgery (VATS) for non-small-cell lung cancer of the left upper lobe. He presented with shortness of breath, fever, and leukocytosis. Chest radiography showed atelectasis at the remaining left lower lobe. Bronchoscopy revealed narrowing of the left lower Bronchus with purulent secretion, and computed tomography showed downward kinking of the left lower Lobar Bronchus. He underwent exploratory VATS, and intraoperative findings showed an inferiorly kinked left lower Lobar Bronchus with upward displacement of the left lower lobe. After adhesiolysis, the kinked Bronchus was straightened, and bronchopexy was performed to the pericardium to prevent the recurrence of bronchial kinking. Also, the inferior pulmonary ligament was reattached to prevent upward displacement. Postoperative follow-up bronchoscopy revealed no evidence of residual bronchial obstruction, and chest radiography showed no atelectasis thereafter.

  • enlarged mediastinal air cyst in a patient with bronchial diverticula localized in the left main Bronchus a case report with surgical and bronchoscopic findings
    Surgical Case Reports, 2017
    Co-Authors: Hideo Ichimura, Yuichiro Ozawa, Masanari Shiigai, Seiji Shiotani, Kazunori Kikuchi, Yukio Sato
    Abstract:

    A mediastinal air cyst is a rare computed tomography (CT) finding. Once the lesion is identified, it is difficult to diagnose and treat. Meanwhile, bronchial diverticula have been reported as a CT finding observed in certain pulmonary pathologic conditions. We encountered the case of an enlarged mediastinal air cyst accompanied with bronchial diverticula and upper lobe-dominant fibrous changes of the lung. A 69-year-old man with a chronic cough who had regularly visited a chest physician for upper lobe-dominant pulmonary fibrosis was referred to our hospital for the examination of an enlarged mediastinal air cyst. Chest CT exhibited an air cyst (size, 30 mm) connected to the lumen of the left main Bronchus (LMB) and multiple tiny outpouches only on the LMB. Flexible bronchoscopy showed bubbling from slits or indentations of the bronchial mucosa only in the LMB but not in the right main Bronchus or Lobar Bronchus. For therapeutic diagnosis, we removed the air cyst. Based on clinical, surgical, and pathological findings, we diagnosed the air cyst as an enlarged bronchial diverticulum. This is the first case wherein bronchoscopic and surgical findings of bronchial diverticula and an enlarged bronchial diverticulum are reported. There are possible pathogenic mechanisms in cases of pulmonary disease that are attributable to enlargement of the bronchial diverticula.
