Incidence, Results, and Our Current Intraoperative Technique to Control Major Vascular Injuries During Minimally Invasive Robotic Thoracic Surgery.

BACKGROUND: Our objective is to report our incidence, results, and technique for the control of major vascular injuries during minimally invasive robotic thoracic surgery. METHODS: This is a consecutive series of patients who underwent a planned robotic thoracic operation by one surgeon. RESULTS: Between February 2009 and September 2015, 1,304 consecutive patients underwent a robotic operation (lobectomy, n = 502; segmentectomy, n = 130; mediastinal resection, n = 115; Ivor Lewis, n = 103; thymectomy, n = 97; and others, n = 357) by one surgeon. Conversion to thoracotomy occurred in 61 patients (4.7%) and in 14 patients (1.1%) for bleeding (pulmonary artery, n = 13). The incidence of major vascular injury during anatomic pulmonary resection was 2.4% (15 of 632). Of these, 13 patients required thoracotomy performed in a nonurgent manner while the injury was displayed on a monitor, 2 had the vessel repaired minimally invasively, 2 required blood transfusion (0.15%), and 1 patient had 30-day mortality (0.16%). Techniques used to minimize morbidity include having a sponge available during vessel dissection and stapling, applying immediate pressure, delaying the opening until the bleeding is controlled without external pressure, and ensuring there is no bleeding while the chest is opened. CONCLUSIONS: Major vascular injuries can be safely managed during minimally invasive robotic surgery. Our evolving technique features initial packing of the bleeding for several minutes, maintaining calmness to provide time to prepare for thoracotomy, and reexamination of the injured vessel. If repair is not possible minimally invasively, the vessel is repacked and a nonhurried, elective thoracotomy is performed while the injury is displayed on a monitor to ensure active bleeding is not occurring.

Transcatheter aortic valve replacement program in the post-food and drug administration approval era: early outcomes at an academic medical center.

OBJECTIVE: Transcatheter aortic valve replacement (TAVR) has recently become a suitable alternative for treatment of symptomatic aortic stenosis in patients who are at very high risk for morbidity and mortality with conventional corrective surgery. In the fall of 2011, the Food and Drug Administration approved the use of TAVR, allowing for reimbursement at institutions outside of investigative trials. We report the initiation of a TAVR-based program at an academic tertiary care facility that did not participate in the Placement of Aortic Transcatheter Valves (PARTNER) 1 or PARTNER II trials. METHODS: A total of 160 patients were evaluated for TAVR from May 2012 through June 2013. Transcatheter aortic valve replacement was found to be appropriate for 50 (31%). RESULTS: In this experience, morbidity and mortality were similar to those reported for the PARTNER trial (30-day hospital mortality was 8%). A single case of presumed cerebrovascular accident was observed. These results demonstrate that the real-world application can be done with comparable results. Implementation of lessons learned in the trials allowed a very short learning curve and excellent results after only a limited number of patients. Use of computed tomography reconstructed images for operative planning, including fluoroscopic angle, facilitated minimal use of contrast in each case. CONCLUSIONS: Transcatheter aortic valve replacement is a viable option for patients at very high risk for surgical intervention in the post-Food and Drug Administration approval era. Real-world results comparable with published outcomes from experienced centers involved in the PARTNER trial can be achieved.
