Brachycephalic Obstructive Airway Syndrome

Juga dikenal sebagai: Brachycephalic Airway Syndrome, Brachycephalic Syndrome, BOAS, BAS, Upper airway obstruction syndrome

Ditinjau dokter hewanCatDogUrgensi: HighSeberapa umum: Common

Singkatnya

Brachycephalic Obstructive Airway Syndrome (BOAS) is a common, inherited condition affecting flat-faced pets. It occurs when compressed facial anatomy restricts airflow, causing severe breathing difficulties, heat intolerance, and digestive issues. Early surgical intervention is highly effective at restoring normal breathing and preventing life-threatening airway collapse.

TL;DR. Penyakit pernapasan herediter pada ras muka datar: saluran sempit, usaha inspirasi, intoleransi panas, risiko rebah; sering perlu bedah.

Saluran napas normal versus saluran terkompresi brakisefalik.

Apa itu?

Jaringan lunak berlebih di tengkorak pendek: nares stenotik, palatum molle memanjang, kadang trakea hipoplastik; tekanan negatif dan kolaps laring sekunder.

Penyebab dan faktor risiko

Kongenital brakisefalik. Anjing: pug, French Bulldog, English Bulldog, Boxer, Pekingese, Chinese Shar-Pei, Boston Terrier. Kucing: Persia, Himalaya. Lebih buruk dengan obesitas dan panas.

Tanda

  • Usaha inspirasi (kardinal)
  • Stertor, stridor, mendengkur, intoleransi olahraga/panas, muntah/regurgitasi
  • Darurat: sianosis, rebah, stridor kuat

Diagnosis

Pemeriksaan; laringoskopi di bawah sedasi (emas); endoskopi, radiografi toraks, kadang gas darah.

An endoscopic view of an elongated soft palate blocking the larynx.
Palatum molle memanjang menyumbat laring.

Pengobatan

Darurat: oksigen, pendinginan, sedasi, Glucocorticoids. Bedah: perluasan nares, stafiektomi, reseksi sakulus.

Prognosis

Baik dengan bedah dini; hati-hati jika kolaps laring lanjut.

Pencegahan

Pembiakan bertanggung jawab, berat kurus, hindari panas, harness (bukan kalung).
