Operative Techniques in Thoracic and Cardiovascular Surgery最新文献

The Ross procedure is superior as a valve substitute in children and early adulthood because of its clear survival benefits. The free standing-root implantation is associated with failure of the autograft and inclusion techniques that support externally the autograft warrants its longevity. The current technique consists in the implantation of the autograft within the native aortic root thereby both supporting the autograft and avoiding any coronary distortion.

Autograft stabilization has proven beneficial in adults but the same technique could not always be adopted in growing children undergoing the Ross procedure. The major concern regarding the longevity of autograft after the Ross operation in a growing child is the lack of means to stabilize the aortic root. Herein we described a modified root inclusion technique that achieves aortic root stabilization using autologous tissue.

Though their etiology and pathology are distinct, the treatment of symptomatic diaphragm eventration and paralysis is the same – diaphragm plication. Though there is little data to objectively compare plication techniques, all offer significant improvement in symptoms, pulmonary function, and respiratory quality-of-life scores. Nonetheless, potential advantages of a robot assisted laparoscopic approach to plication include lower morbidity than thoracotomy and laparotomy techniques; avoidance of single lung ventilation, less intercostal nerve pain, and greater working domain compared with thoracotomy and thoracoscopic approaches; and enhanced dexterity as compared with standard laparoscopic instrumentation.

Aberrant subclavian arteries are a result of unusual involution of the branchial arches resulting in persistent arteries that can cause tracheal or esophageal compression. Many are incidental findings but may be associated with dysphagia (dysphagia lusus naturae, Latin for “jest of nature”), a long history of asthma treatment for wheezing, or more uncommonly, aneurysms or aortic dissection. There are 5 basic approaches for repair discussed herein, determined by which subclavian artery is involved and where the aortic arch and descending thoracic aorta lie, as well as the size of the latter, classified as Groups A to E, in order of frequency. These include: A: Aberrant RSCA and left arch; B: Aberrant LSCA and right arch; C: Aberrant RSCA, no significant Kommerell's and descending aneurysm; D: Aberrant LSCA and right-sided arch but compression from a vascular ring; and E: Aberrant RSCA and extensive arch and descending aneurysm.

Postinfarction ventricular septal rupture, or postinfarction ventricular septal defect is rare but lethal if not repaired, and various repair techniques have been tried over many years. However, there still remain problems of high mortality rates and shunt recurrence, particularly in the acute phase and posterior defects. The extended sandwich patch repair via the right ventriculotomy was developed to overcome those problems. The 3 key features are, first, access and eventual closure through the low-pressure right ventricle; second, using the septal defect for a portal to reach into the left ventricle; and third, “sandwiching” the defect between 2 patches, both large enough to be anchored by transmural sutures through relatively stable myocardium. Detailed technical steps are presented here.

When replacement of the aortic valve in neonates and infants is required, the Ross-Konno procedure provides a high-quality left ventricular outflow with good mid-term durability. The procedural outcome is highly dependent on the pre-procedural condition of the neonate or infant. Most series contain substantial numbers of post-balloon valvotomy patients as emergent or urgent management of severe, acute regurgitation. In patients with compromised ventricular function, post-operative mechanical support may be required but is generally associated with a good outcome. The neonatal and infant autograft may perform better in the long term than un-supported autografts performed later in life. Early definitive or delayed treatment of left ventricular outflow tract pathology associated with aortic interruption increasingly involves an infant Ross-Konno. The procedure also has a role in the recruitment of small left ventricles. Concomitant mitral pathology or aortic obstruction magnifies complexity, but the operative approach to the Ross-Konno remains the same.

The technique of minimally invasive esophagectomy (MIE) has been improved and utilized widely in the past decades, resulting in improved perioperative outcomes compared to open esophagectomy. Similarly, robotic assisted minimally invasive esophagectomy (RAMIE) has increased in adoption in recent years, offering superior technical advantages and showing promising outcomes. This article details the approach to the RAMIE Ivor Lewis procedure adopted at the University of Pittsburgh Medical Center, including operative insights and challenges.
