Three-dimensional cranial geometric morphometrics of syringomyelia in toy breed dogs

Kohei Nakata, Tomoka Ono, Yui Kobatake, Takahiro Nagumo et autres

Syringomyelia (SM) is a neurological disorder characterized by fluid accumulation within the spinal cord and is frequently observed in toy breed dogs. Cranial malformations associated with Chiari-like malformation are considered a major cause; however, previous studies have relied mainly on midsagittal imaging, …

Reconstruction of single large abdominal wall defects in 2 dogs using expanded polytetrafluoroethylene-based mesh.

Takahiro Nagumo, Reina Fujiwara, Kohei Nakata, Masaaki Katayama et autres

Repairing large abdominal wall defects in veterinary medicine is challenging. Polypropylene mesh is the synthetic mesh most used for reconstructions. However, adhesion formation has been reported with its use. We report the reconstruction of large abdominal wall defects using expanded polytetrafluoroethylene (ePTFE)-based …

Dynamic transition from spinal arachnoid diverticulum to syringohydromyelia in a cat : Correlation between computed tomography myelography and magnetic resonance imaging

Kohei NAKATA, Minoru Matsuno, Makoto Komatsu, Takahiro Nagumo et autres

Background: Diseases characterized by impaired spinal cord function due to fluid accumulation include syringohydromyelia (SHM) and spinal arachnoid diverticulum (SAD). SHM refers to fluid-filled cavities within the spinal cord, whereas SAD involves fluid accumulation in the subarachnoid space. Although the true incidence …

Resolution of a persistent pneumothorax by blood patch pleurodesis in a cat ( Felis catus ) with primary pulmonary lymphoma

Reina Fujiwara, Masaaki Katayama, Kohei Nakata, Takahiro Nagumo et autres

Abstract An 18‐year‐old, spayed, female, domestic shorthair cat was presented to our hospital with acute dyspnoea following an episode of vomiting. Thoracic radiography revealed a severe pneumothorax. Despite multiple thoracocenteses, the pneumothorax persisted. Under general anaesthesia, computed tomography revealed multiple pulmonary masses. …
