Sternal elevation techniques during the minimally invasive repair of pectus excavatum
Interactive CardioVascular and Thoracic Surgery, 2019
Summary The aim of the review was to evaluate the routine use of sternal elevation techniques (SETs) during minimally invasive repair of pectus excavatum (MIRPE, the Nuss procedure). We performed a review of the literature between January 1998 and September 2018 with focus on different methods of SET during MIRPE. Reported effects and side effects were evaluated and compared with our own experience concerning the routine use of the vacuum bell for sternal elevation during MIRPE during the last 13 years. SET is more often used in adult patients than in adolescents. SET improves visualization and safety of MIRPE. Advancement of the pectus introducer, retrosternal dissection and placement of the pectus bar are easier. The risk of cardial and/or pericardial lesion is reduced significantly. Different types of retractors, a crane combined with a wire and/or customized hooks are reported to be used as SET. Furthermore, routine use of a subxiphoid incision is reported. However, more technic...

OBJECTIVES: Patients with pectus excavatum (PE) after prior sternotomy for cardiac surgery present unique challenges for repair of PE. Open repairs have been recommended because of concerns about sternal adhesions and cardiac injury. We report a multi-institutional experience with repair utilizing substernal Nuss bars in this patient population. METHODS: Surgeons from the Chest Wall International Group were queried for experience and retrospective data on PE repair using substernal Nuss bars in patients with a history of median sternotomy for cardiac surgery (November 2000 to August 2015). A descriptive analysis was performed. RESULTS: Data for 75 patients were available from 14 centres. The median age at PE repair was 9.5 years (interquartile range 10.9), and the median Haller index was 3.9 (interquartile range 1.43); 56% of the patients were men. The median time to PE repair was 6.4 years (interquartile range 7.886) after prior cardiac surgery. Twelve patients (16%) required resternotomy before support bar placement: 7 preemptively and 5 emergently. Sternal elevation before bar placement was used in 34 patients (45%) and thoracoscopy in 67 patients (89%). Standby with cardiopulmonary bypass was available at 9 centres (64%). Inadvertent cardiac injury occurred in 5 cases (7%) without mortality. CONCLUSIONS: Over a broad range of institutions, substernal Nuss bars were used in PE repair for patients with a history of sternotomy for cardiac surgery. Several technique modifications were reported and may have facilitated repair. Cardiac injury occurred in 7% of cases, and appropriate resources should be available in the event of complications. Prophylactic resternotomy was reported at a minority of centres.
A 10-year review of a minimally invasive technique for the correction of pectus excavatum
Journal of Pediatric Surgery, 1998
The aim of this study was to assess the results of a 10-year experience with a minimally invasive operation that requires neither cartilage incision nor resection for correction of pectus excavatum. From 1987 to 1996, 148 patients were evaluated for chest wall deformity. Fifty of 127 patients suffering from pectus excavatum were selected for surgical correction. Eight older patients underwent the Ravitch procedure, and 42 patients under age 15 were treated by the minimally invasive technique. A convex steel bar is inserted under the sternum through small bilateral thoracic incisions. The steel bar is inserted with the convexity facing posteriorly, and when it is in position, the bar is turned over, thereby correcting the deformity. After 2 years, when permanent remolding has occurred, the bar is removed in an outpatient procedure. Of 42 patients who had the minimally invasive procedure, 30 have undergone bar removal. Initial excellent results were maintained in 22, good results in four, fair in two, and poor in two, with mean follow-up since surgery of 4.6 years (range, 1 to 9.2 years). Mean follow-up since bar removal is 2.8 years (range, 6 months to 7 years). Average blood loss was 15 mL. Average length of hospital stay was 4.3 days. Patients returned to full activity after 1 month. Complications were pneumothorax in four patients, requiring thoracostomy in one patient; superficial wound infection in one patient; and displacement of the steel bar requiring revision in two patients. The fair and poor results occurred early in the series because (1) the bar was too soft (three patients), (2) the sternum was too soft in one of the patients with Marfan's syndrome, and (3) in one patient with complex thoracic anomalies, the bar was removed too soon. This minimally invasive technique, which requires neither cartilage incision nor resection, is effective. Since increasing the strength of the steel bar and inserting two bars where necessary, we have had excellent long-term results. The upper limits of age for this procedure require further evaluation.
Upper sternal depression following Lorenz bar repair of pectus excavatum
Pediatric Surgery International, 2008
An upper sternal depression following Lorenz bar repair of pectus excavatum (PE) represents a partial recurrence and poses a difficult problem for the surgeon. There is no published experience detailing the management options or best course of therapy for this complication. This study presents our institutional experience in treating eight patients with this specific subtype of recurrence and we discuss intraoperative considerations which aid in the identification and better management of this deformity. A retrospective review (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006) of patients undergoing primary repair of PE with a Lorenz bar procedure identified eight patients who experienced upper sternal depression with the bar still in place following initial repair of PE. All patients were revised with the insertion of a second bar to elevate the upper sternal depression. Data collected for each patient included demographics, preoperative symptoms, operative characteristics, and postoperative outcomes. The mean age at the time of Lorenz bar repair and surgical revision was 20.8 ± 9.5 and 21.5 ± 10.1 years, respectively. A majority of patients (87.5%) were male. The mean time to reoperation was 23.8 ± 11.8 months. Following this second procedure, no patient has experienced bar displacement, recurrence of the upper sternal depression, or has required a third procedure. Our limited experience supports the use of a second Lorenz bar in the treatment of upper sternal depression after bar correction of a PE deformity. Appropriate recognition and treatment of this entity will advance patient outcomes and satisfaction after surgery for PE deformities.
Nuss procedure in adult pectus excavatum: a simple artifice to reduce sternal tension
Interactive CardioVascular and Thoracic Surgery, 2013
Nowadays the Nuss operation represents the standard surgical choice for pectus excavatum repair in children and teenagers. Some concerns have been raised regarding its applicability in adults, as compared with younger patients, in view of the higher rate of complications after surgery. We describe an easy trick that has been performed on a 36-year-old man with a moderate pectus excavatum after an unsatisfactory Nuss procedure. It consisted of a T-shaped partial anterior sternotomy, performed after positioning Q3
A simple technique for preventing bar displacement with the nuss repair of pectus excavatum
Journal of Pediatric Surgery, 2001
Background/Purpose: The most common complication of the minimally invasive technique for repair of pectus excavatum (MIRPE) is bar displacement, which has been reported to occur in 9.5% of all cases, particularly in teenaged patients. The use of a lateral stabilizing bar has improved stability but has not eliminated the occurrence of this problem. The authors report a new technique added to the standard MIRPE that creates an additional third point of fixation of the pectus bar to prevent displacement.
Management of a floating sternum after repair of pectus excavatum
Journal of Pediatric Surgery, 2001
The aim of this study was to examine the authors' experience with patients who have floating sternum after correction of pectus excavatum via the classical Ravitch procedure. A floating sternum is defined as a sternum in which the only attachment to the chest wall is its superior (cranial) border, and in which the body is secured only by the manubrium and whatever lateral and inferior fibrous bands are present. Typically, a floating sternum is caused by either extensive resection of the costal cartilages and perichondrium during correction of pectus excavatum or failure of proper regrowth of these cartilages.

Use of sternal plate for pectus excavatum repair in adults leads to minimal postoperative pain
Journal of surgical case reports, 2018
Pectus excavatum is a chest wall deformity that results in caved-in or sunken appearance of lower half of anterior chest. Surgical treatment is favored when functional or cosmetic concerns arise. We present a case and series of six patients (mean haller index: 4.28) who had repair with minimal pleural disruption and sternal plate. After a broad bilateral inframammary skin incision, the anterior aspect of sternum is identified and incised. Next, the surgeon hyperextends and fixates the bone in its desired position by applying manual dorsal pressure through a small intercostal incision. Superior and inferior fasciocutaneous flaps are raised and then advanced to reconstruct the soft tissue defect. All patients had durable repair of the chest wall abnormalities and they had minimal pain during the postoperative period. No analgesia medication was necessary 1 month post-operatively. This may provide significantly less pain compared to the Nuss or Ravitch procedures to fix Pectus excavatum.
