Acute Respiratory Arrest

Intraoperative cardiovascular collapse in an infant with Arnold‐Chiari malformation

“…Segal et al observed haemodynamic to be due to brainstem compression caused by caudal displacement of the cerebellar vermis and the dilated modulation by pulsatile compressions exerted on the ventrolateral surface of the medulla in cats (16). fourth ventricle, resulting in kinking of the medulla oblongata, microvascular lesions in the brainstem, Sieben et al emphasized that multiple cranial deficits were present in children with ACM, and and tractions or compressions of lower cranial nerves (2,(4)(5)(6)(7). The vasomotor centre lies in close proximity demonstrated microscopic atrophy of the nucleus ambiguous and shrunken neurons (18).…”

“…of neurons extending from the upper portion of the medulla oblongata to the hypothalamus, and Children with Arnold-Chiari malformation (ACM) is adjacent to the respiratory centre. Despite the manifest various respiratory signs and symptoms proximity and the common vascular supply of these associated with dysfunctions of cranial and upper two centres, severe cardiovascular complications cervical nerves, compression of the brainstem, and attributed primarily to the central dysfunction, but increased intracranial pressure (1)(2)(3)(4)(5). In the previous not secondary to apnoea or increased intracranial literature, these manifestations were attributed pressure, are limited in the literature (8).…”
