Median sternotomy - gold standard incision for cardiac surgeons (original) (raw)

The Median Sternotomy: The Unkindest Cut of All? Pearls, Pitfalls, Aphorisms, Myths

The Heart Surgery Forum

While some have claimed that a median sternotomy is an ‘unkind cut,’ when this incision is performed, closed, and managed optimally, it can be one of the ‘most kind cuts’ used for major operations. The median sternotomy is the most commonly used incision for coronary artery bypass surgery, which is the most common operation performed in the United States at the current time. This approach is, of course, used for many other cardiac and thoracic operations, as well. It is, however, also one of the most misunderstood procedures in Surgery. Because it is an incision that even a novice surgical resident can perform, with proper supervision, the subtleties and nuances of not only opening but also of closing sternotomies are not often conveyed optimally to our trainees. In this treatise we will attempt to comprehensively address these subtleties, nuances, and misunderstandings, both for the benefit of our younger learners, but also, and more importantly, for the benefit of our patients.

Subtotal median sternotomy for heart surgery

European Journal of Cardio-Thoracic Surgery, 2000

Objective: Many approaches for minimally invasive heart surgery are available. Although they have many advantages, inadequate exposure, mammary artery injury and special tool requirements are known problems. Subtotal median sternotomy (SMS) was developed to overcome such limitations. Comparing the SMS with the standard sternotomy (SS) is the purpose of this study. Methods: SMS was used in 210 patients (group I) requiring coronary artery bypass grafting and or valvular surgery. This was compared with another 210 patients (group II) in which SS was used. The technical dif®culties, incisional discomfort, wound infection, patient satisfaction and hospital stay are the comparison criteria. Results: (1) SMS takes an average of 24 min longer, P , 0:15. (2) Incisional discomfort graded (I`least' to IIÌ greatest'), group I: (27 Grade I, 176 Grade II, seven Grade III). Group II: (21 Grade I, 183 Grade II, six Grade III), P , 0:1. (3) Wound infection: two super®cial, two deep in group I, four super®cial and one deep in group II, P , 0:06, (4) 99% satisfaction and 5.4 days mean hospital stay in group I, 63% and 7.1 days in group II, P , 0:01 and , 0.03, respectively. Conclusion: When comparing the SMS technique with the SS: (1) SMS has statistically signi®cant better patient satisfaction; (2) can be very cost effective due to the short hospital stay and the absence of a need for special instruments.

Sternal wound closure in the current era: the need of a tailored approach

General Thoracic and Cardiovascular Surgery, 2019

Objective Median sternotomy remains the most common access to perform cardiac surgery procedures. However, the experience of the operating surgeon remains a crucial factor during sternal closure to avoid potential complications related to poor sternal healing, such as mediastinitis. Considering the lack of major randomized controlled trials and the heterogeneity of the current literature, this narrative review aims to summarize the different techniques and approaches to sternal closure with the aim to investigate their reflections into clinical outcomes and to inform the choice on the most effective closure method after median sternotomy. Methods A literature search through PubMed, Embase, EBSCO, Cochrane database of systematic reviews, and Web of Science from its inception up to April 2019 using the following search keywords in various combinations: sternal, sternotomy, mediastinitis, deep sternal wound infection, cardiac surgery, closure. Results Single wire fixation methods, at present, seems the most useful method to perform sternal closure in routine patients, although patients with a fragile sternum might benefit more from a figure-of-eight technique. In high-risk patients (e.g. chronic pulmonary disease, obesity, bilateral internal mammary artery harvesting, diabetes, off-midline sternotomy), rigid plate fixation is currently the most effective method, if available; alternatively, weave techniques could be used. Conclusion The choice among the sternal closure techniques should be mainly inspired and tailored on the patient's characteristics, and correct judgement and experience play a pivotal role. A decisional algorithm has been proposed as an attempt to overcome the absence of specific guidelines and to guide the operative approach. This operative approach might be used also in non-cardiac procedure in which median sternotomy is required, such as in case of thoracic surgery.

Less invasive cardiac operations through a median sternotomy: 100 consecutive cases

The Annals of Thoracic Surgery, 1998

Background. In the beginning of 1997, we developed a routine approach to intracardiac operations through a less invasive median sternotomy. A limited (6 to 9 cm) median skin incision followed by a subcomplete (manubrium and body) median sternotomy makes opening and closing of the chest easier; conventional central cardiopulmonary bypass is instituted, and no modifications to the surgical techniques are necessary.

Figure-of-Eight vs. Interrupted Sternal Wire Closure of Median Sternotomy

2009

Sternal dehiscence is a rare but devastating complication following median sternotomy for cardiac surgery. The optimal technique for sternal closure is unclear. We conducted this prospective randomized trial to compare the incidence of sternal dehiscence after figure-of-8 and simple interrupted suturing in patients undergoing coronary artery bypass grafting. Between January 2007 and June 2008, 98 patients had figure-of-8 suturing and 97 had interrupted sutures. The mean age of the patients was 60.9 AE 7.6 years. The overall sternal dehiscence rate was 8%; 7 cases in the in figure-of-8 group and 9 in the interrupted group. Thirteen patients had no wound infection and healed with conservative treatment. Only 3 patients had sternal dehiscence with infection: 2 with simple interrupted closure and 1 with figure-of-8 sternal closure. There was no significant difference in rates of sternal dehiscence between the 2 groups. It was concluded that figure-of-8 sternal suturing is equally effective as simple interrupted suturing in preventing sternal dehiscence.

The versatility of median sternotomy in general paediatric surgery

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde

Background. While common in cardiac surgery, median sternotomy (MS) is rarely required in general paediatric surgery. In the era of advancing endoscopic techniques, sternotomy is perceived as an extremely invasive incision, associated with prolonged postoperative recovery and significant morbidity.Methods. We conducted a retrospective chart review of all children undergoing MS for non-cardiac indications between January 2007 and September 2012 and describe the pathology, number of ventilated days, duration of intensive care unit stay and analgesic requirements. Results. Our experience over the past 6 years includes 14 children, aged between 8 months and 13 years. Indications for surgery included penetrating mediastinal trauma (1), anterior and posterior mediastinal masses (4), acquired tracheo-oesophageal fistulas secondary to button battery impaction (2), bronchial foreign bodies (2) and bilateral pulmonary metastases secondary to malignancy (5). The range of postoperative ventilat...

A review of sternal closure techniques

Sternotomy and sternal closure occur prior to and post cardiac surgery, respectively. Although post-operative complications associated with poor sternal fixation can result in morbidity, mortality, and considerable resource utilization, sternotomy is preferred over other methods such as lateral thoracotomy. Rigid sternal fixation is associated with stability and reduced incidence of post-operative complications. This is a comprehensive review of the literature evaluating in vivo, in vitro, and clinical responses to applying commercial and experimental surgical tools for sternal fixation after median sternotomy. Wiring, interlocking, plate-screw, and cementation techniques have been examined for closure, but none have experienced widespread adoption. Although all techniques have their advantages, serious post-operative complications were associated with the use of wiring and/or plating techniques in high-risk patients. A fraction of studies have analyzed the use of sternal interlocking systems and only a single study analyzed the effect of using kryptonite cement with wires. Plating and interlocking techniques are superior to wiring in terms of stability and reduced rate of post-operative complications; however, further clinical studies and long-term follow-up are required. The ideal sternal closure should ensure stability, reduced rate of post-operative complications, and a short hospitalization period, alongside cost-effectiveness.

Comparison of straight sternotomy and interlocking sternotomy in open heart surgery

The Indian Journal of Medical Research

Background & objectives: Stable sternal approximation is an important factor to avoid respiratory complications after open heart surgery. The present study is designed to compare interlocking sternotomy and straight sternotomy in terms of sternal stability, pain and respiratory function. Methods: Sixty patients scheduled for open heart surgery underwent a standard midline sternotomy (n=30) or an interlocking sternotomy (n=30). The features assessed were pain on visual analogue scale during rest and during cough, peak expiratory flow rate and sternal instability. Evaluation was performed on the first, fourth post-operative days, on discharge and one month and three month follow up. Results: Analysis of the peak expiratory flow rates, visual analogue ratings of pain intensity at rest and on coughing were carried out for each group only for those patients who completed the study. Postoperatively, in all patients there was significant reduction in peak expiratory flow rates. In the straight sternotomy group resting pain intensity was higher on discharge (2.6 ± 2 vs 1.6 ± 2.3, P= 0.005). In the interlocking sternotomy group pain on coughing was significantly less than straight sternotomy group (median 0.5 vs 2.8, P=0.005) at 1 month follow up and at 3 months (median 0 vs 1.6, P=0.003). Interpretation & conclusion: Interlocking sternotomy can be performed with good functional results and offers a less painful alternative to straight sternotomy.
