Association between deep neck space abscesses and internal carotid artery narrowing in pediatric patients

Abstract

Background/aim: Our aim was to interpret the effects of deep neck space abscesses on the adjacent carotid artery according to abscess location, as well as to determine narrowing by calculating the mean stenosis ratios.Materials and methods: Neck computed tomography scans and clinical data of 45 children with neck abscesses were evaluated retrospectively for abscess location and internal carotid artery narrowing. The lumen areas of the carotid arteries were measured from standard levels, and stenosis ratios were calculated with two different techniques. The mean stenosis ratios of each group according to abscess location were then compared with the control group.Results: Among the 45 abscesses included in the study, 51.1% (n = 23/45) were located in the peritonsillar region, 37.8% (n = 17/45) were located in the parapharyngeal-lateral retropharyngeal space, and 11.1% (n = 5/45) were in the midline retropharyngeal space. We found a statistically significant difference between the mean stenosis ratios of the ipsilateral side of the parapharyngeal-lateral retropharyngeal abscesses and the control group (P < 0.01).Conclusion: The children with parapharyngeal-lateral retropharyngeal abscesses all had narrowing in the adjacent carotid lumen to some degree. Although most of the patients had no clinical symptoms, radiologists have to be aware of this arterial complication to prevent further progress and fatal complications.

Effects of phenolic acids from ginseng rhizosphere on soil fungi structure, richness and diversity in consecutive monoculturing of ginseng

“…Microbial diversity and community composition significantly affect agricultural soil productivity, plant growth, and crop quality (Nayyar et al, 2009, Wu et al, 2011). Variation in the diversity and composition of the microbial community is believed to be related to changes in many factors (Derinkuyu et al, 2017, Mandava et al, 2017, Salameh et al, 2018, Scoppa et al, 2017). Such as cropping systems and root exduates (Bell et al, 2013, Yang et al, 2014).…”

The Spectrum of Pediatric Infection-Associated Intracranial Arteriopathies and Acute Ischemic Stroke at 2 Eastern Indian Tertiary Care Centres

“…37,38 Although all these studies described hemiplegia as a neurodeficit similar to our results, none reported fusiform dilatation of the cavernous segments of the internal carotid arteries prior to retrograde occlusion. However, 2 studies 39,40 found asymptomatic and reversible internal carotid artery narrowing in 58 children with a deep neck space infection.…”

Vascular Complications of Parapharyngeal Abscesses

“…Perforation or rupture require surgery or endovascular stenting procedures [13]. Children with parapharyngeal lateral retropharyngeal abscesses (n=45) all had narrowing in the adjacent carotid lumen to some degree in a study by Derinkuya et al [14].…”

“…The two main vascular complications reported in the literature are extrinsic carotid artery stenosis due to compression by the abscess and pseudoaneurysm [14,15]. Internal carotid artery aneurysms can mimic peritonsillar abscess and incision drainage can be fatal [16].…”
