Detection of Residual Disease with CT Scan after Surgery of Juvenile Nasopharyngeal Angiofibroma

Abstract

study was to elucidate the effects of VCAP on sleep and the utility of awake and sleep laryngoscopy in MSA.Methods: We recruited 14 patients with MSA presenting with snoring (4 men and 10 women; mean age, 54.6 years; disease duration, 4.2 years; International Cooperative Ataxia Rating Scale [ICARS], 46.9). After performing arterial blood gas analysis, spirometry, and polysomnography (PSG), awake and sleep laryngoscopy were performed.Results: Sleep laryngoscopy revealed that 7 patients exhibited VCAP and 7 patients did not. Between these 2 groups, there were no significant difference in the following findings: sex, disease duration, ICARS, findings of daytime blood gas analysis and PSG findings (mean SpO2 during sleep, AI, AHI and arousal index). Five of 7 patients who exhibited VCAP also showed bilateral arytenoidal tremor on awake laryngoscopy.Conclusion: These findings suggest that MSA should be followed by sleep laryngoscopy, however, it is difficult to perform sleep laryngoscopy as a routine evaluation. Since early diagnosis of VCAP is difficult to make on awake laryngoscopy, arytenoidal tremor may be useful as a sign to predict VCAP.

Liquid Embolic Agents for Endovascular Embolization: A Review

“…The use of cyanoacrylate (CA) glues for polymerization in the presence of blood was proposed in the 1970s [3]. N-butyl-2-cyanoacrylate (NBCA) (Histoacryl, Avacryl and Trufill n-BCA), often referred to as the "Glues", was introduced as an embolic agent in the 1980s and Trufill n-BCA was approved by the US Food and Drug Administration (FDA) in 2000 for use in the treatment of cerebral arteriovenous malformations [4,27,28] by replacing the carcinogenic Isobutyl-2-cyanoacrylate due to its predictable polymerization qualities, ease of surgical resection, and low toxicity [29,30]. Due to the adhesive nature of NBCA, it can mechanically occupy the intravascular lumen and stop blood flow regardless of blood coagulability [4,31,32].…”

Postoperative Computed Tomographic Assessment of the Complete Resection of an Infiltrative Lipoma Compressing the Spinal Cord in a Dog

“…While the implementation of intraoperative CT scanning has been reported in human medicine [11], research in veterinary medicine has been limited. A human case report suggested that in patients with juvenile nasopharyngeal angiofibroma, contrast-enhanced CT scanning 2.8 ± 1.8 days after surgery could detect residual tumor cells even when the resection was deemed complete [12]. However, in dogs, anesthesia is required to control respiration and obtain image optimization for thorough residual mass evaluation.…”
