The Authors report a case of diaphragmatic eventration associated with Wolff-Parkinson-White's syndrome. It's difficult to explain this unusual association. It's possible that the presence of cardiac accessory pathways in this particular patient is due to the alteration of the normal anatomical relationship resulting from the diaphragmatic eventration.
A case of right diaphragmatic eventration, associated with a lung sequestration, in a 7-month-old infant is presented. Failure to thrive was the initial symptom. X-ray of the chest, made because of mild respiratory distress, revealed an inhomogeneous opacification of the right lower hemithorax, suggesting a diaphragmatic hernia. A right thoracotomy was performed and a diaphragmatic eventration covered by a thick pleuroperitoneal membrane was found, together with sequestration of the lung. The pathologic findings and the embryology are discussed.
A 59-year-old woman was admitted to our hospital because of left diaphragmatic eventration due to a left phrenic nerve injury following surgery for recurrent thyroid cancer. She underwent plication by thoracoscopic surgery followed by marked expansion of the left lung and improvement of pulmonary function and dyspnea on exercise. Thoracoscopic plication for diaphragmatic eventration is a useful minimally invasive surgical technique.
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.

Indication for surgical treatment and its results are reported in 17 consecutive cases of diaphragmatic eventration in pediatric age. Fourteen of the patients are males and 3 are females. Eleven of them had a right eventration 6 had a left eventration. Three of the patients were new-born, 13 were aged from 6 months to 3 years and 1 was aged 6 years. Two patients had gastroesophageal reflux, 1 had right intralobar pulmonary sequestration, and another had inguinal hernia. In 2 of the new-born the eventration was caused by a phrenic nerve palsy (in 1 case resulting from birth trauma, while in the other one resulting from multiple thoracentesis). In this last patient surgical treatment wasn't performed, and restitutio ad integrum was observed in 4 weeks' time. The indication for surgical treatment in 2 new-born patients was persistent polypnoea and dyspnoea unresponsive to medical treatment, in 12 of the patients were relapsing bronchitis and bronchopneumonia. Moreover 1 patient with few symptoms but with important diaphragmatic eventration was operated. In all the patients a diaphragmatic plication with fixing of the diaphragmatic plica to the ribs was performed through a thoracic approach. Neither complication or deaths were noticed. There was an immediate remission of the symptomatology in all the cases examined. No relapse of eventration or restarting of the symptomatology was found during a follow-up for a period of 2 to 8 years.
A 56-year-old woman underwent plication with U-stitches by thoracoscopic surgery for left diaphragmatic eventration. Marked improvement in left lung expansion, normalization of the position of the left diaphragm on chest radiograph, and improvement of pulmonary function and dyspnea on exertion have been maintained for 2 years. Plication for diaphragmatic eventration should be performed with minimally invasive surgery.
Two sporadic cases of eventration of the diaphragm are reported; one had bilateral colobomatous microphthalmia and the other had anophthalmia. Absence of polydactyly and presence of eventration rather than diaphragmatic hernia helped to exclude Fryns syndrome. These cases together with published cases with overlapping features support the thesis that this combination of defects is nonrandom and of heterogeneous cause. Some cases are due to a pleiotropic gene defect. In other cases, a polytypic developmental field involving an unknown developmental cascade common to the eye and diaphragm may provide a basis for the combination.
A stillborn full term foal was presented at necropsy. The dilated duodenum and the dorsal and ventral left colon and cecum extended into the thoracic cavity and were encased by a thin transparent membrane originating from the diaphragm. The congenital condition was diagnosed as a developmental anomaly with diaphragmatic eventration. To the authors' knowledge, this is the first report of diaphragmatic eventration in a Thoroughbred stillborn foal.

We describe a patient who presented with a left lower lobe lung lesion suspicious for cancer with possible hilar involvement. Intraoperatively, we found a primary left phrenic nerve tumor, diaphragmatic eventration, and left lower lobe atelectasis. He was successfully treated with total excision of the tumor and plication of the diaphragm. Histopathology was consistent with schwannoma of the phrenic nerve. Diaphragmatic eventration is an uncommon presentation of a phrenic nerve schwannoma, which is itself a rarely occurring tumor. Surgical resection of the tumor and diaphragmatic plication is the primary modality of management in these patients.
Bronchopulmonary foregut malformations are uncommon anomalies, and their association with diaphragmatic eventration is rare. This report presents 2 cases with this association. Embryologically, a simultaneous disturbance in the development of pulmonary vessels and developing esophagotracheal septum may explain the etiopathogenesis of this association. Abnormal budding along the developing foregut tube may lead to foregut cysts. In both cases, the bronchopulmonary foregut malformations were excised, and the diaphragm was repaired. The results of surgery were gratifying in both cases.
The authors report two cases of neonatal partial diaphragmatic eventration. The diagnosis in both two cases was echographic more than radiographic. The authors underline the role of B-mode echography in the diagnosis and follow-up of diaphragmatic anomalies, especially eventration, and suggest that examination of diaphragm and of its motion should complete any abdominal and thoracic echography.
The case was a 59-year-old man who has a history of left mediastinal tumor resection with left phrenicectomy. The elevated diaphragm revealed by chest X-ray 7 years after the operation led to diagnosis of diaphragmatic eventration. Since any symptom was seen in the early period, "wait and watch" strategy was done for management. Both the abdominal enlarged feeling and the dyspnea on effort were appeared 10 years after the operation. Under the speculation of these symptoms related to the elevated abdominal organs came up with diaphragmatic eventration, surgical method the plication of the diaphragm was performed. The diaphragm was plicated by interrupted suture as opening the diaphragm to avoid injury the abdominal organs, and reinforced with the Marlex mesh. We used artificial mesh to reinforce the thin diaphragm with exceptation of prevent the postoperative recurrence, because a result of the etiological process of the case was considered as disuse atrophy of diaphragm after phrenicectomy.

The Authors report a case of asymptomatic right partial diaphragmatic eventration, casually discovered and surgically repaired by imbrication of the hemidiaphragm. They confirm the almost completely asymptomatic and benign character of this disease, and discuss the difficulty of the differential diagnosis with various diseases of the right cardiophrenic angle, particularly the pericardial cysts. Among the diagnostic techniques the Authors advocate the priority of the liver scanning, the echotomography, the C.A.T., the pneumoperitoneography and, in case, the celiac axis arteriography. They consider the plastic repair of the diaphragm performed by a thoracic approach to be indispensable to the confirmation of the diagnosis and, of course, to a radical therapy.
