costochondritis英 [kɒstəʊ'kɒndraɪtɪs] 美 [kɒstoʊ'kɒndraɪtɪs]   

释义   n. [医] 肋软骨炎

例句   Costochondritis is an inflammation at the junction of a rib and its cartilage.

肋软骨炎是一种肋骨和软骨连接区的炎症。

概述

一、疾病概述或定义非特异性肋软骨炎,国外学者称 Tietzes 综合征,是胸痛的常见病因之一,患者常常因为胸部疼痛或者局部肋软骨肿胀前来诊治。同时又因为该病易复发且与乳腺科、普外科、心内科等胸疼症状疾病相混淆,困扰着患者及广大临床医生。 二、致病因素或病理机制病因不明确,考虑:①大多数学者认为与肋软骨膜微小创伤及胸肋关节韧带和肋间内、外肌局部应力异常造成的劳损有关;②也有学者认为与上呼吸道病毒感染有关,导致胸肋关节面的软骨发生水肿,增厚而导致的无菌性炎症;③还有学者认为与免疫调节、内分

Pneumoperitoneum detected in the setting of blunt trauma has classically been thought of as highly suggestive of perforated viscus, requiring urgent laparotomy and surgical repair in the absence of other recognized causes. With the widespread adoption of CT in evaluating trauma patients, identification of small, apparently intraperitoneal, locules of gas is a frequent event; however, many of these patients do not have a perforated viscus. Abdominal ectopic gas is a well-recognized phenomenon in patients with pneumomediastinum and pulmonary interstitial air. The pulmonary interstitial air is able to track centrally along the bronchovascular bundles down a pressure gradient into the mediastinum by a process known as the Macklin effect. The mediastinal gas is then able to migrate caudally along fascial planes via two main pathways: The first pathway is posteriorly through the diaphragmatic hiatuses into the retroperitoneum, and the second pathway is anteriorly from the chest wall into the extraperitoneal space through the Morgagni foramen or along the internal thoracic and superior epigastric vessels. The caudal migration of mediastinal gas through these fascial planes into the extraperitoneal space can resemble pneumoperitoneum. The formation of abdominal ectopic gas via this mechanism has been described in patients on mechanically assisted ventilation, patients who have sustained traumatic alveolar rupture or a tracheobronchial injury, and patients with chest tubes in situ.

在钝性创伤中检测到的气腹通常被认为是穿孔内脏的高度暗示,需要在没有其他公认原因的情况下进行紧急剖腹手术和手术修复。随着CT在评估创伤患者中的广泛应用,鉴定小的,明显腹膜内的气体是经常发生的事件;然而,许多这些患者没有穿孔的内脏。腹部异位气体是肺气肿和肺间质气体患者公认的现象。肺间质空气能够通过称为麦克林效应的过程沿着支气管血管束向下沿着压力梯度向下追踪进入纵隔。然后纵隔气体能够通过两条主要通道沿着筋膜平面向尾侧移动:第一条通路通过膈肌裂孔向后进入腹膜后通道,第二条通路通过Morgagni孔或沿着胸壁向前通过Morgagni孔进入腹膜外空间内胸和上腹部血管。纵隔气体通过这些筋膜平面向腹膜外空间的尾部迁移可能类似于气腹。通过这种机制形成腹部异位气体已经在机械辅助通气患者,持续性外伤性肺泡破裂或气管支气管损伤的患者以及原位胸管患者中进行了描述。
