Abstract
An elevated diaphragm may be due to eventration or paralysis. Diaphragm elevation is often asymptomatic and found incidentally on imaging. Fluoroscopic testing can be used to differentiate eventration (no paradoxic motion) from paralysis (paradoxic motion). Regardless of etiology, a diaphragm plication is indicated in all symptomatic patients with an elevated diaphragm. Plication can be approached either from a thoracic or abdominal approach, though most thoracic surgeons perform minimally invasive thoracoscopic plication. The goal of plication is to improve lung volumes and decrease paradoxic elevation of the hemidiaphragm. Diaphragm plication is safe, has excellent outcomes, and is associated with symptom improvement.

A Rare Case of Contralateral Diaphragm Paralysis following Birth Injury with Brachial Plexus Palsy: A Case Report and Review of the Literature. Case Rep Pediatr 2020; 2020:8844029. [PMID: 33274099 PMCID: PMC7676972 DOI: 10.1155/2020/8844029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 10/05/2020] [Accepted: 10/23/2020] [Indexed: 11/29/2022] Open
Abstract
Clinical History. A 4.4 kg male was born to a 25-year-old, G2P1, nondiabetic woman at 39 and 5/7 weeks. Delivery was complicated by shoulder dystocia requiring forceps-assisted vaginal delivery, resulting in left arm Erb's palsy secondary to left brachial plexus injury. He was born with low muscle tone and bradycardia and subsequently required intubation for poor respiratory effort. He was extubated on day one of life but continued to be tachypneic and have borderline oxygen saturation, requiring intensive care. Chest radiographs demonstrated a progressive clearing of his lung fields, consistent with presumptively diagnosed meconium aspiration. However, a persistent elevation of the right hemidiaphragm was noted, and his tachypnea and increased work of breathing continued. Focused ultrasound of the diaphragm was performed, confirming decreased motion of the right hemidiaphragm. Following a multidisciplinary discussion, thoracoscopic right diaphragm plication was performed on the 33rd day of life. He was extubated postoperatively and subsequently weaned to room air with a notable decrease in tachypnea over 48 hours. He was discharged on postoperative day 12 and continues to thrive at 6 months of age without respiratory embarrassment. Purpose. Ipsilateral phrenic nerve injury with diaphragm paralysis from shoulder dystocia during vaginal delivery is a recognized phenomenon. Herein, we present a case of contralateral diaphragm paralysis in order to draw attention to the clinician that this discordance is possible. Key Points. According to Raimbault et al., clinical management of newborns who experience birth injury is a multidisciplinary effort. According to Fitting and Grassino, though most cases of phrenic nerve injuries are ipsilateral to shoulder dystocia brachial plexus palsy, contralateral occurrence is possible and should be considered. According to Waters, diaphragm plication is a safe and effective operation.

Abstract
BACKGROUND Phrenic nerve injury (PNI) from birth trauma is a recognized phenomenon, generally occurring with ipsilateral brachial plexus palsy (BPP). In severe cases, PNI results in diaphragm paresis (DP) and respiratory insufficiency. Surgical diaphragmatic plication (SDP) is a potential management strategy for patients with PNI and DP, but timing and outcomes associated with SDP have not been rigorously studied. METHODS Records from 49 tertiary United States pediatric hospitals in the Pediatric Health Information System from 2004 to 2018 were analyzed. The study cohort included patients diagnosed with BPP from birth trauma who were documented to have PNI or DP. Patients who underwent congenital cardiac operations were excluded. RESULTS A total of 5832 patients were identified with BPP from birth trauma during the study period, 122 (2%) of whom were found to have concomitant DP. Of those, 65 (53%) were male, 39 (32%) were infants of diabetic mothers, 80 (65%) required mechanical ventilation, and 33 (27%) underwent SDP. SDP was performed at a median (range) age of 36 (7-95) days. Median (range) total and postoperative hospital lengths of stay (LOS) were 34 (6-180) and 15 (4-132) days, respectively. There was also an observed increase in post-operative LOS with increase in age at operation. CONCLUSION Neonatal DP is rare and is managed with SDP in a minority of instances. Age at repair affects total and postoperative length of stay, proxies for resource utilization and morbidity. Repair prior to 45 days of life appears to result in a shorter postoperative hospital stay. This analysis will help guide surgeons with respect to indications and operative timing for infant DP. TYPE OF STUDY Retrospective Comparative Study. LEVEL OF EVIDENCE Level III.

Abstract
AIM To develop examination algorithm and to determine the indications for various options for surgical treatment. MATERIAL AND METHODS It is presented analysis of surgical treatment of 25 patients with unilateral diaphragm relaxation for the period from 1963 to 2016. There were 15 men and 10 women aged from 39 to 65 years. Diagnosis included predominantly radiological methods. All patients were operated openly through thoracotomy. Procedure consisted of creation of new diaphragmatic cupola at the usual level with two flaps of diaphragm and prosthesis between them. In 12 (48%) patients who were operated before 1990 xenopericardial patch was used. Further, synthetic materials (Teflon, polypropylene) were preferred. RESULTS Postoperative morbidity and mortality was 20% (n=6) and 4% (n=1) respectively. Long-term results were followed-up within terms from 8 months to 12 years. Recurrent relaxation was absent. Most of patients had improved dyspnea, increased vital capacity and FEV1 in long-term period. Certain and general values of SF-36 life quality questionnaire were high in long-term postoperative period and similar to those in general population.

Abstract
BACKGROUND Phrenic neurofibromas are a rare pathologic entity, with 9 cases described in the English literature. They may occur in conjunction with or independently of neurofibromatosis type 1. Phrenic neurofibromas pose distinct therapeutic challenges compared with the more common phrenic schwannoma. We describe here a 12-year-old boy with neurofibroma of the left phrenic nerve presenting as dextroposition of the heart after paralysis of the left hemidiaphragm allowed herniation of abdominal contents into the left hemithorax and displaced the heart. METHOD Surgical resection of the tumor followed by diaphragmatic plication was performed to assess its degree of malignancy, reduce abdominal herniation, and improve lung capacity. RESULTS The operation markedly improved his hemidiaphragmatic elevation. CONCLUSIONS The spectrum of management options ranges from conservative surveillance to open thoracic surgery. Functional preservation of the phrenic nerve is technically challenging, and although phrenic neurofibromas often present with absent function that cannot be recovered, surgical intervention can be fruitful in restoring lung capacity through diaphragmatic reconstruction.

Abstract
Diaphragmatic plication is the most accepted treatment for symptomatic diaphragmatic hernia in adults. The fact that this pathology is infrequent and this procedure not been widespread means that this is an exceptional technique in our field. To estimate its use in the literature, we carried out a review in English and Spanish, to which we added our series. We found only six series that contribute 59 video-assisted mini-thoractomy for diaphragmatic plications in adults, and none in Spanish. Our series will be the second largest with 18 cases. Finally, we conducted a survey in all the Spanish Thoracic Surgery units in Spain: none reported more than 10 cases operated by thoracoscopy in the last 8 years (except our series) and most continue employing thoracotomy as the main approach. We believe that many patients with symptomatic diaphragmatic hernia could benefit from the use of such techniques.

Abstract
The clinical presentations of diaphragm dysfunctions vary according to etiologies and unilateral or bilateral diseases. Elevation of the hemidiaphragm from peripheral origins, the most frequent situation, requires a surgical treatment only in case of major functional impact. Complete morphological and functional analyses of the neuromuscular chain and respiratory tests allow the best selection of patients to be operated. The surgical procedure may be proposed only when the diaphragm dysfunction is permanent and irreversible. Diaphragm plication for eventration through a short lateral thoracotomy, or sometimes by videothoracoscopy, is the only procedure for retensioning the hemidiaphragm. This leads to a decompression of intrathoracic organs and a repositioning of abdominal organs without effect on the hemidiaphragm active contraction. Morbidity and mortality rates after diaphragm plication are very low, more due to the patient's general condition than to surgery itself. Functional improvements after retensioning for most patients with excellent long-term results validate this procedure for symptomatic patients. In case of bilateral diseases, very few bilateral diaphragm plications have been reported. Some patients with diaphragm paralyses from central origins become permanently dependent on mechanical ventilation whereas their lungs, muscles and nerves are intact. In patients selected by rigorous neuromuscular tests, a phrenic pacing may be proposed to wean them from respirator. Two main indications have been validated: high-level tetraplegia above C3 and congenital alveolar hypoventilation from central origin. After progressive reconditioning of the diaphragm muscles following phrenic pacing at thoracic level, more than 90% of patients can be weaned from respirator within a few weeks. This weaning improves the quality of life with more physiological breathing, restored olfaction, better sleep and better speech. The positive impact of diaphragm stimulation has also been evaluated in other degenerative neurological diseases, particularly the amyotrophic lateral sclerosis. For either central or peripheral diaphragm dysfunctions, a successful surgical treatment lies on a strict preoperative selection of patients.

Early hemi-diaphragmatic plication through a video assisted mini-thoracotomy in postcardiotomy phrenic nerve paresis. J Thorac Dis 2013; 4 Suppl 1:56-68.

Abstract
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.

Abstract
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was as follows: In adults with unilateral diaphragmatic paralysis, does diaphragmatic plication offer functional improvement in dyspnoea, better pulmonary function tests (PFTs) and return to activity? A total of 126 papers were found using the reported search, of which 13 represented the best evidence to answer the clinical question. The authors, date and country of publication, patient group studied, surgical approach, study type, relevant outcomes and results of these articles are tabulated. Those articles reporting improvement in PFTs following plication, documented this benefit in the following parameters: mean forced vital capacity (range 17-40%), forced expiratory volume at 1 sec (range 21-27%), functional residual capacity (range 20-21%) and total lung capacity (range 16-19%). The percentage of postoperative improvement in shortness of breath as measured by a dyspnoea score was reported to be between 90 and 96% in the thoracotomy group and 100% in the Video Assisted Thoracoscopic Surgery (VATS) group, the dyspnoea score that was used in all the studies was a visual analogue scale between 0 and 10 where 0 is no dyspnoea and 10 is the worst dyspnoea a patient can have. One of the studies reported postoperative normalization in ventilation perfusion scan (VQ) scan parameters when compared with the preoperative mismatch. Complication rate was similar between the two groups, while the mortality rate was 4% in the thoracotomy group and 0% in the VATS group. The total number of patients included in all the studies combined was 161. All reports included in this review are observational studies (one cohort study and the remainder being case series); therefore, the risk of selection, information and publication biases are high and conclusions should be implemented with caution. We conclude that diaphragmatic plication can improve the functional status, shortness of breath and PFTs of patients with unilateral diaphragm paralysis. Patients undergoing a VATS approach appear to have more advantages in objective and subjective measures (including PFTs, dyspnoea score, length of hospital stay and postoperative complications). Further research with high-quality study designs is advised, focussing mainly on the long-term benefits and assessment of health-related quality of life.

Abstract
Surgical treatment of eventration or paralysis of the diaphragm is symptomatic and non curative, and depends on whether the dysfunction is of peripheral or central origin. Elevation of a hemidiaphragm of peripheral origin, the most frequent situation, needs surgical treatment only in case of major functional effects (effort or positional dyspnoea, cardiac or digestive symptoms, or pain) that persists despite optimal conservative management. Selection of candidates for surgery depends on a thorough morphological and functional investigation of the neuromuscular and respiratory components. Surgical plication of the diaphragm through a lateral thoracotomy or by video-thoracoscopy is a recognized, safe and effective procedure. Its low morbidity and mortality, which are mainly associated with co-morbid factors, and its long-lasting functional benefit of around 100%, show that it is an effective procedure. In the case of bilateral dysfunction, occasional cases of bilateral plication have been reported. Some cases of diaphragmatic paralysis of central causation result in a life of ventilator dependence, even though the peripheral neuromuscular and respiratory systems are intact. In selected cases, following a complete functional investigation, phrenic nerve pacing may be attempted to achieve ventilator weaning. To date, there are two validated indications for this technique: Tetraplegia above C3 and alveolar hypoventilation of central cause. After thoracic implantation, a progressive reconditioning of the diaphragmatic muscle allows weaning from the ventilator in a few weeks in more than 90% of patients. Their quality of life is greatly improved thanks to independence from the ventilator, more physiological respiration, restoration of smell and better speech. Whether the diaphragmatic dysfunction is peripheral or central in origin, the success of surgical treatment depends on rigorous preoperative selection of patients.

Abstract
BACKGROUND This study seeks to evaluate results regarding the repair of diaphragmatic eventration using video-assisted thoracic surgery (VATS). METHODS We performed a prospective observational study including patients referred to us for surgical treatment of diaphragmatic eventration during a 12-year period. Clinical, radiologic, and functional data were prospectively recorded. VATS was performed with two thoracoports and a 4-cm mini-thoracotomy. Diaphragmatic plication was performed using two nonresorbable running sutures from periphery to the cardio-phrenic angle. Follow-up data (clinical examination, chest roentgenogram, lung function tests at 3, 6, 12 months, and annually thereafter) were also prospectively recorded. RESULTS Twelve patients (4 male adults, mean age 57.7 +/- 14.8 years) were operated on between 1992 and 2003. The left side was involved in 8 patients and the mean height of diaphragm elevation was 7.5 +/- 1.8 cm. All patients experienced symptoms related to the disease; in 2 patients the operation was carried out to achieve weaning from mechanical ventilation. The etiologic mechanism could be identified in 11 out of 12 patients (trauma, n = 9; Charcot-Marie disease, n = 1; calcified para-aortic nodes, n = 1). Mean operative time, drainage output, and hospital stay were 77 +/- 15 minutes, 0.8 +/- 04 L, and 3.4 +/- 0.7 days, respectively. No mortality was observed; 1 patient experienced postoperative pneumonia, which was treated using antibiotics. All patients experienced amelioration of symptoms and long-term lung function tests revealed a marked improvement of both the forced volume capacity and the forced expiratory volume at 1 second. No relapses were observed at follow-up chest roentgenogram. CONCLUSIONS Treatment using VATS is a safe and effective alternative to conventional surgery. Functional improvement persists at long-term follow-up.

Abstract
BACKGROUND Paralysis of the diaphragm is a severe complication of cardiothoracic surgery carrying significant morbidity and mortality. This study demonstrates a novel minimally invasive technique for treatment of phrenic nerve injuries presenting with symptomatic eventration of the diaphragm. It also presents long-term results of three patients treated with this operation. METHODS Chest x-ray proved eventration of the left diaphragm in all patients. Two patients required treatment due to prolonged respirator therapy/assisted ventilation for 4 weeks after cardiac surgery. One patient suffered from progressive dyspnea caused by increasing left-sided diaphragmatic elevation and underwent surgery 2 years after cardiac surgery. In all cases, a minimally invasive abdominal approach was chosen. During surgery the dome of the diaphragm was pulled down via three percutaneously inserted retention stitches. This resulted in two or three folds of the diaphragm located within the abdomen. These diaphragmatic folds were subsequently tightened using 12 to 15 unresorbable sutures with extracorporally prepared knots. Surgical as well as long-term follow-up results are presented of all patients and a review of the current literature is provided. RESULTS Mean operating time was 203 min; mean intraoperative blood loss was 130 ml. No major complications occurred during surgery or the postoperative period. At a median follow-up of 72 months no recurrence was observed. CONCLUSIONS Laparoscopic diaphragmatic plication provides excellent relief of symptoms caused by diaphragmatic paralysis. There is no perioperative morbidity, and hospital stay is short. The laparoscopic approach, therefore, is an attractive surgical alternative for the treatment of phrenic nerve palsy and should be considered in all suitable patients.

Abstract
BACKGROUND The right phrenic nerve is at risk of injury during high mobilization of the right internal mammary artery (RIMA). The incidence and implications of this injury have not been previously defined. METHODS Prospectively collected data on all patients who underwent RIMA harvesting between January 1995 and February 2002 were analyzed. Thirty-one patients with right phrenic nerve injury were identified and the medical charts reviewed. Phrenic nerve injury was diagnosed when a postoperative chest roentgenogram showed the right hemidiaphragm to be two or more intercostal spaces higher than the left, or transection of the nerve was seen intraoperatively. Investigations included fluoroscopy and spirometry in upright and supine positions. Diaphragm plication was offered for symptom control. Subsequent follow-up was undertaken to determine the incidence of spontaneous recovery of diaphragm function and the benefits of diaphragm plication. RESULTS Seven hundred and eighty-three patients underwent high mobilization of the RIMA with proximal detachment for use as a free graft. Thirty-one patients with right hemidiaphragm dysfunction were identified in the postoperative period providing an injury incidence of 4% (confidence interval, 2.6% to 5.3%). Of these, 12 patients underwent diaphragm plication (4 early and 8 late), 14 patients achieved spontaneous recovery, and 5 patients were lost to follow-up. The supine to upright forced vital capacity ratios at the time of phrenic nerve dysfunction, after diaphragm plication, and after spontaneous recovery were 0.79, 0.90, and 0.96 respectively. CONCLUSIONS The incidence of phrenic nerve injury associated with high RIMA harvesting was 4% but spontaneous recovery may be anticipated in two thirds (14 of 22) of patients in whom the injury is identified postoperatively. High RIMA harvesting should be used with caution in patients with preoperative pulmonary dysfunction in whom phrenic nerve injury would be poorly tolerated.

Abstract
BACKGROUND Diaphragm paralysis after cardiac surgery may be secondary to phrenic nerve injury by ice, electrocautery, or dissection. Although most are asymptomatic, some patients, particularly children, have significant respiratory compromise. Video-assisted plication may offer more rapid improvement and recovery than thoracotomy in pediatric patients. METHODS We performed five procedures. The diaphragm was elevated, clamped, oversewn, and tacked down into the pleural gutter. The procedure was performed on 2 infants after repair of total anomalous pulmonary venous connection, on 1 child after the Fontan procedure, on 1 child after repair of tetralogy of Fallot, and on 1 child with congenital eventration. Indications included ventilator dependency, post-Fontan protein losing enteropathy with elevated venous pressures and chronic right lower lobe collapse, persistent atelectasis with recurrent pneumonias, and asymptomatic severe eventration. RESULTS Ventilator-dependent patients were extubated after 2 and 3 days. The remaining patients were immediately extubated. One patient was discharged the day of surgery and 2 were discharged at 1 and 3 days postoperatively. The remaining 2 were discharged on postoperative day 30 and 45 after continued issues with feeding and prematurity. The child with the eventration had rapid expansion and growth of the left lung over the next few weeks with a normal chest radiograph 3 weeks later. The child with recurrent pneumonia reexpanded her left lower lobe and remains free of infection. There were no wound infections, lung or vascular injuries, or complications from the procedure. All the patients had successful flattening of the hemidiaphragm as documented by chest radiograph, with successful lung reexpansion. CONCLUSIONS Video-assisted plication of paralyzed diaphragms is effective and safe, involves less morbidity, and has quicker recovery times than traditional open techniques.

Abstract
We describe a simple technique for video-assisted thoracoscopic plication in patients with diaphragmatic eventration. During the plication, which is performed with a continuous running suture, a surgical assistant maintains the continuous suture traction using a homemade hook through the port. The technique can be performed easily, without any kind of thoracotomy.
