RESUMEN
BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) as direct bridge-to-transplantation (dBTT) remains controversial. We compared the short- and long-term outcomes of adult patients undergoing urgent heart transplantation (HT) with (dBTT) and without (non-BTT) VA-ECMO support at the time of HT. METHODS: Adults who underwent urgent HT in two institutions were assessed (N = 133; dBTT: N = 34 and non-BTT: N = 99). Patient characteristics, donor characteristics, in-hospital outcomes, and overall survival were compared. Mean follow up was 77±38 months and was 100% complete. Mortality predictors were identified using univariate and multivariate analyses. RESULTS: Before HT, patients with dBTT had higher rates of ischemic cardiomyopathy, acute kidney injury, liver failure, respiratory failure, and longer graft ischemia times. More patients in the dBTT group had complications, such as requiring VA-ECMO postoperatively (dBTT=50% vs. non-BTT=20%, P < 0.01). Hospital deaths (dBTT=23% vs. non-BTT=19%, P = 0.58), one-year (74% vs. 80%) and five-year survival (62% vs. 75%, P = 0.74 for overall survival) were not significantly different. The MELD-XI score and previous cardiac surgery were independent predictors of hospital mortality. CONCLUSION: Direct bridge-to-transplantation in patients on VA-ECMO support was not associated with worse long-term outcomes compared with non-VA-ECMO urgent HT, especially in recipients without any associated organ failure and a low MELD-XI score before HT.

BACKGROUND: The decision about whether to use venoarterial extracorporeal membrane oxygenation (VA-ECMO) in patients with cardiac graft dysfunction (GD) is usually made on a case-by-case basis and is guided by the team's experience. We aimed to determine the incidence of VA-ECMO use after heart transplantation (HT), to assess early- and long-term outcomes and to assess risk factors for the need for VA-ECMO and early mortality in these patients. METHODS: We included adults who underwent heart transplantation at 3 cardiac centres who met the most recent International Society for Heart and Lung Transplantation definition of graft dysfunction (GD) over a 10-year period. Pre-transplant, intraoperative and posttransplant characteristics of the heart recipients as well as donor characteristics were analyzed and compared among recipients with GD treated with and without VA-ECMO. RESULTS: There were 135 patients with GD in this study, of whom 66 were treated with VA-ECMO and 69 were not. The mean follow-up averaged 81.2 months (standard deviation 36 mo, range 0-184 mo); follow-up was complete in 100% of patients. The overall incidence of GD (30%) and of VA-ECMO use increased over the study period. We did not identify any predictive pre-transplantation factors for VA-ECMO use, but patients who required VA-ECMO had higher serum lactate levels and higher inotropes doses after HT. The overall survival rates were 83% and 42% at 1 year and 78% and 40% at 5 years among patients who received only medical treatment and those who received VA-ECMO, respectively. Delayed initiation of VA-ECMO and postoperative bleeding were strongly associated with increased in-hospital mortality. CONCLUSION: The incidence of GD increased over the study period, and the need for VA-ECMO among patients with GD remains difficult to predict. In-hospital mortality decreased over time but remained high among patients who required VA-ECMO, especially among patients with delayed initiation of VA-ECMO.

OBJECTIVES: Severe compensatory hyperhidrosis (CH) is a disabling complication following thoracic sympathectomy. Our study was to establish valid patient selection criteria and determine outcomes of nerve reconstructive surgery. Furthermore, we assessed the clinical feasibility and safety of a robotic-assisted approach compared to video-assisted thoracoscopic surgery. METHODS: Adults with severe CH following bilateral sympathectomy for primary hyperhidrosis were enrolled. We performed 2 questionnaires: the Hyperhidrosis Disease Severity Scale and the Dermatology Life Quality Index before and 6 months after nerve reconstructive surgery. A one-time evaluation of healthy volunteers (controls) was undertaken to validate the quality of life measures. RESULTS: Fourteen patients (mean age 34.1 ± 11.5 years) underwent sympathetic nerve reconstruction. None of the patients had a recurrence of primary hyperhidrosis. Improvement in quality of life was reported in 50% of patients. Both mean Hyperhidrosis Disease Severity Scale and mean Dermatology Life Quality Index were significantly reduced compared to preoperative assessments. In 10 patients, a video-assisted approach and in 4 patients robotic assistance was utilized. There was no significant difference in outcomes between approaches. CONCLUSIONS: Somatic-autonomic nerve reconstructive surgery offers a reversal in the debilitating symptoms in some patients with severe CH. Proper patient selection, preoperative counselling and management of expectation are of paramount importance. Robot-assisted thoracic surgery is an alternative method to conventional video-assisted surgery. Our study provides a practical approach and benchmark for future clinical practice and research.
RESUMEN
BACKGROUND: Understanding near-death experiences (NDE) could provide a new insight into the analysis of human consciousness and the neurocognitive processes happening upon the approach of death. With a temporary interruption of systemic perfusion, aortic surgery under hypothermic circulatory arrest (HCA) may be the only available model of reversible clinical death. We present, herein, the results of an observational study designed to assess the incidence of NDE after aortic surgery. METHODS: We performed a prospective study including consecutive patients who underwent thoracic aortic surgery between July 2018 and September 2019 at our institution. Procedures without HCA were included to constitute a control group. The primary outcome was the incidence of NDE assessed with the Greyson NDE scale during the immediate postoperative course, via a standardized interview of the patients in the surgical ward. RESULTS: One hundred and one patients were included. Twenty-one patients (20.8%) underwent nonelective interventions for aortic dissection. Ninety-one patients had hemiarch replacement (90.1%). Sixty-seven (66.3%) interventions were performed with HCA, with an average circulatory arrest duration of 26.9 ± 25.5 minutes, and a mean body temperature of 23.7 ± 3.8°C. None of the patients reported any recollection from their period of unconsciousness. There was no NDE experiencer in the study cohort. CONCLUSION: Several confounding factors regarding anesthesia, or NDE evaluation, might have impaired the chance of NDE recollections, and might have contributed to this negative result. Whether HCA may trigger NDE remains unknown.
RESUMEN
AIMS: The aim of this study was to document the postoperative outcomes of patients who underwent hypothermic circulatory arrest (HCA), the evolution of HCA management over time and to identify the risks factor for early mortality and postoperative stroke. METHODS: Four hundred and twenty-four patients who underwent aortic surgery with HCA at our institution between January 1995 and June 2016 were consecutively included. RESULTS: The main indications were degenerative aneurysm (254; 59.9%) and acute type A aortic dissection (146; 34.4%). Interventions were performed under deep (18.4â±â0.9°C; nâ=â350; 82.5%) or moderate (23.9â±â1.9°C; nâ=â74; 17.5%) hypothermia. Antegrade cerebral perfusion (ACP) was employed in 86 (20.3%) cases. The use of moderate hypothermia significantly increased from 2011, to become the preferred strategy in 2016. The in-hospital mortality was 12.5% and the postoperative stroke rate was 7.1%. Kaplan--Meier 5-year survival was 65.7%. Nonelective timing [odds ratio (OR) 4.05; Pâ<â0.001], stroke (OR 3.77' Pâ=â0.032), renal failure (OR 2.49; Pâ=â0.023), redo surgery (2.42; Pâ=â0.049) and CPB time (OR 1.05; Pâ=â0.03) were independent risk factors for in-hospital mortality in multivariate analysis. Femoral cannulation was the only independent risk factor for stroke (OR 3.97; Pâ=â0.002). The level of hypothermia and the use of ACP were not associated with either in-hospital mortality or postoperative stroke. CONCLUSION: HCA might be widely considered to achieve a radical treatment of the aortic disease, provided that hypothermia is maintained below the 24°C safety threshold and ACP is used for HCA exceeding 30âmin, to ensure optimal brain, spinal cord and visceral organs protection.

BACKGROUND: With the progressive aging of the population, aortic surgeons are caring for an increasing number of elderly patients. The objective of this study was to analyze early and late outcomes of aortic surgery with hypothermic circulatory arrest in patients aged 70 and above at our institution. METHODS: We performed a retrospective cohort study including every patient aged 70 years or older who underwent aortic surgery with hypothermic circulatory arrest between January 1995 and June 2016 at our institution. Operative results were compared with the contemporary younger counterparts aged <70 years. In-hospital mortality and postoperative stroke were primary outcomes of interest. The main secondary outcomes included acute renal failure, reoperation for bleeding, and spinal cord injury. RESULTS: In the study population, the in-hospital mortality was 16.8% (21/125). Ten (8.0%) patients presented postoperative stroke, and 6 had temporary neurologic disturbance (4.8%). Spinal cord injury occurred in 1 (0.8%) patient. For elective interventions and type A aortic dissections, the in-hospital mortality and stroke rates were 4.6% (3/65) and 7.7% (5/65), 26.8% (11/41) and 12.2% (5/41), respectively. The proportion of non-elective interventions, including type A aortic dissection, and the type of neuroprotective strategy were similar in septuagenarians and younger patients. Patients aged ≥70 had significant shorter cardiopulmonary bypass, myocardial ischemia, and circulatory arrest durations, compared to their younger counterparts. The in-hospital mortality of septuagenarians and younger patients were similar for elective surgery (4.6% vs. 4.7%, P=0.900) and aortic dissections (26.8% vs. 15.1%, P=0.107). There was no statistically significant difference between the two age groups regarding postoperative stroke, spinal cord injury, renal failure requiring dialysis or reintervention for bleeding. Estimated 1-, 3-, and 5-year survival was 78.0%, 70.6%, and 65.7%, respectively. The 5-year survival for elective surgery was 74.9% and 56.0% for non-elective procedures. CONCLUSIONS: Aortic surgery with circulatory arrest in the elderly demonstrated favorable early and late results when compared with younger individuals, with an acceptable operative risk even under emergency conditions, and should not be denied only because of the chronological age of the patients.

Bronchobiliary fistula is a rare pathology mainly caused by hepatic tumors, bile duct obstruction, or hepatic hydatid disease. A 70-year-old man developed a bronchobiliary fistula after biliary stenting. After failure of conservative treatment including endoscopic retrograde biliary drainage, he underwent a combined operation with a two-level approach. Both a thoracotomy and laparotomy were performed, allowing pulmonary resection, diaphragmatic repair, and bile duct reconstruction during the same operation. Postoperative follow-up at one year showed optimal healing of the fistula.
