New symptom onset of respiratory distress without other cause, and new hemi-diaphragmatic elevation on chest radiography postcardiotomy, are usually adequate for the diagnosis of phrenic nerve paresis. The symptom severity varies (asymptomatic state to severe respiratory failure) depending on the degree of the lesion (paresis vs. paralysis), the laterality (unilateral or bilateral), the age, and the co-morbidity (respiratory, cardiac disease, morbid obesity, etc). Surgical treatment (hemi-diaphragmatic plication) is indicated only in the presence of symptoms. The established surgical treatment is plication of the affected hemidiaphragm which is generally considered safe and effective. Several techniques and approaches are employed for diaphragmatic plication (thoracotomy, video-assisted thoracoscopic surgery, video-assisted mini-thoracotomy, laparoscopic surgery). The timing of surgery depends on the severity and the progression of symptoms. In infants and young children with postcardiotomy phrenic nerve paresis the clinical status is usually severe (failure to wean from mechanical ventilation), and early plication is indicated. Adults with postcardiotomy phrenic nerve paresis usually suffer from chronic dyspnoea, and, in the absence of respiratory distress, conservative treatment is recommended for 6 months -2 years, since improvement is often observed. Nevertheless, earlier surgical treatment may be indicated in non-resolving respiratory failure. We present early (25(th) day postcardiotomy) right hemi-diaphragm plication, through a video assisted mini-thoracotomy in a high risk patient with postcardiotomy phrenic nerve paresis and respiratory distress. Early surgery with minimal surgical trauma, short operative time, minimal blood loss and postoperative pain, led to fast rehabilitation and avoidance of prolonged hospitalization complications. The relevant literature is discussed.
新出现的呼吸窘迫症状,无其他原因,且开胸术后胸部 X 线显示膈肌抬高,通常足以诊断膈神经麻痹。症状严重程度不一(无症状至严重呼吸衰竭),取决于损伤程度(弛缓与瘫痪)、单侧或双侧、年龄和合并症(呼吸、心脏疾病、病态肥胖等)。仅在存在症状时才需要手术治疗(膈神经折叠术)。既定的手术治疗是受累半膈肌折叠术,一般认为安全有效。膈神经折叠术有多种技术和方法(开胸术、电视辅助胸腔镜手术、电视辅助小切口胸腔镜手术、腹腔镜手术)。手术时机取决于症状的严重程度和进展情况。开胸术后膈神经麻痹的婴儿和幼儿通常临床状况严重(无法从机械通气中脱机),需要早期进行折叠术。开胸术后膈神经麻痹的成年人通常患有慢性呼吸困难,在无呼吸窘迫的情况下,建议保守治疗 6 个月至 2 年,因为通常会观察到改善。然而,对于持续存在的呼吸衰竭,可能需要更早进行手术治疗。我们介绍了一位高危开胸术后膈神经麻痹伴呼吸窘迫患者,在术后第 25 天行右侧膈肌折叠术,通过电视辅助小切口完成。这种早期手术创伤小、手术时间短、出血量少、术后疼痛轻,可快速康复并避免长时间住院并发症。讨论了相关文献。
