- BackgroundSingle centre studies support No Touch (NT) saphenous vein graft (SVG) harvesting technique. The primary objective of the SUPERIOR SVG study was to determine whether NT versus conventional (CON) SVG harvesting was associated with improved SVG patency 1year after coronary artery bypass grafting surgery (CABG).MethodsAdults undergoing isolated CABG with at least 1 SVG were eligible. CT angiography was performed 1-year post CABG. Leg adverse events were assessed with a questionnaire. A systematic review was performed for published NT graft patency studies and results aggregated including the SUPERIOR study results.ResultsTwo hundred and-fifty patients were randomized across 12-centres (NT 127 versus CON 123 patients). The primary outcome (study SVG occlusion or cardiovascular (CV) death) was not significantly different in NT versus CON (NT: 7/127 (5.5%), CON 13/123 (10.6%), p=0.15). Similarly, the proportion of study SVGs with significant stenosis or total occlusion was not significantly different between groups (NT: 8/102 (7.8%), CON: 16/107 (15.0%), p=0.11). Vein harvest site infection was more common in the NT patients 1month postoperatively (23.3% vs 9.5%, p<0.01). Including this study's results, in a meta-analysis, NT was associated with a significant reduction in SVG occlusion, Odds Ratio 0.49, 95% Confidence Interval 0.29-0.82, p=0.007 in 3 randomized and 1 observational study at 1year postoperatively.ConclusionsThe NT technique was not associated with improved patency of SVGs at 1-year following CABG while early vein harvest infection was increased. The aggregated data is supportive of an important reduction of SVG occlusion at 1year with NT harvesting.Trial registrationNCT01047449.

- Micro abstract: This study assessed physical performance and health-related quality of life one year after lung cancer surgery and investigated the potential association between both outcomes. We found that the walked distance was associated with the subjective perception of the physical functioning. Patients improved health-related quality of life, reaching values similar to a healthy reference population.Background: Resuming an acceptable level of lifestyle and health-related quality of life after lung cancer surgery has become an important issue. We aimed to evaluate the course of recovery of physical performance and health-related quality of life following pulmonary resection for lung cancer, as well as examine the potential association between these outcomes.Methods: In an observational design, we assessed 78 individuals radically operated for lungcancer. We measured health-related quality of life (SF-36), six-minute walk test (6MWT) and lung function (spirometry)three weeks (baseline), four and twelve months after surgery. SF-36 values were compared to an age-and gender-matched reference population.Results: The mean age was 65 years (SD9), 59% were males. Thoracotomy was performed in 77% of the cases. Compared to baseline values, we found significant improvements after one year in SF-36 physical and mental component summary components of large effect size (0.8 and 0.9 respectively). Values for both SF-36 summary components were comparable to those of the reference population. The improvement in 6MWT was of moderate effect size (0.6). We found a positive association between 6MWT and the SF-36 domain for physical functioning (β=0.05, 95% CI [0.00;0.09], p=0.03) one year after surgery.Conclusion: Individuals who were radically operated for lung cancer improved health-related quality of life one year after surgery, reaching values similar to a healthy reference population. The walked distance was positively associated with the subjective perception of physical functioning. The clinical significance of these findings deserves further investigation.

- OBJECTIVES The aim was to investigate whether 2 weeks of inspiratory muscle training (IMT) could preserve respiratory muscle strength in high-risk patients referred for pulmonary resection on the suspicion of or confirmed lung cancer. Secondarily, we investigated the effect of the intervention on the incidence of postoperative pulmonary complications.METHODS The study was a single-centre, parallel-group, randomized trial with assessor blinding and intention-to-treat analysis. The intervention group (IG, n = 34) underwent 2 weeks of postoperative IMT twice daily with 2 × 30 breaths on a target intensity of 30% of maximal inspiratory pressure, in addition to standard postoperative physiotherapy. Standard physiotherapy in the control group (CG, n = 34) consisted of breathing exercises, coughing techniques and early mobilization. We measured respiratory muscle strength (maximal inspiratory/expiratory pressure, MIP/MEP), functional performance (6-min walk test), spirometry and peripheral oxygen saturation (SpO2), assessed the day before surgery and again 3–5 days and 2 weeks postoperatively. Postoperative pulmonary complications were evaluated 2 weeks after surgery.RESULTS The mean age was 70 ± 8 years and 57.5% were males. Thoracotomy was performed in 48.5% (n = 33) of cases. No effect of the intervention was found regarding MIP, MEP, lung volumes or functional performance at any time point. The overall incidence of pneumonia was 13% (n = 9), with no significant difference between groups [IG 6% (n = 2), CG 21% (n = 7), P = 0.14]. An improved SpO2 was found in the IG on the third and fourth postoperative days (Day 3: IG 93.8 ± 3.4 vs CG 91.9 ± 4.1%, P = 0.058; Day 4: IG 93.5 ± 3.5 vs CG 91 ± 3.9%, P = 0.02). We found no association between surgical procedure (thoracotomy versus thoracoscopy) and respiratory muscle strength, which was recovered in both groups 2 weeks after surgery.CONCLUSIONS Two weeks of additional postoperative IMT, compared with standard physiotherapy alone, did not preserve respiratory muscle strength but improved oxygenation in high-risk patients after lung cancer surgery. Respiratory muscle strength recovered in both groups 2 weeks after surgery.

- Introduction: Optimal surgical management for acute type A aortic dissection (AAAD) remains unclear. The in-hospital mortality rate is still high (15%), and the intraoperative bleeding is an independent risk factor for hospital mortality.Objective: The aim of our study was describe a new method for aortic anastomosis in the repair of AAAD and report the hospital mortality and bleeding complications.Methods: Between January 2008 and November 2014, 24 patients, 16 male, median age 62 years, underwent surgical treatment of AAAD. The surgical technique consisted of intussusception of a Dacron tube in the dissected aorta, which is anastomosed with a first line of 2-0 polyester everting mattress suture and a second line of 3-0 polypropylene running suture placed at the outermost side. Open distal anastomosis was performed with bilateral selective antegrade cerebral perfusion in 13 (54.1%) patients.Results: Cardiopulmonary bypass and aortic clamping time ranged from 75 to 135 min (mean= 85 min) and 60 to 100 min (mean= 67 min), respectively. The systemic circulatory arrest ranged from 29 to 60 min (mean=44.5 min). One (4.1%) patient required reoperation for bleeding, due to the use of preoperative clopidogrel. The postoperative bleeding was 382-1270 ml (mean= 654 ml). We used an average of 4.2 units of red blood cells/patient. There were two (8.3%) hospital deaths, one due to intraoperative bleeding and another due to mesenteric ischemia. The average length of stay in the intensive care unit and hospital was 44 hours and 6.7 days, respectively.Conclusion: This new method for surgical correction of AAAD was reproducible and resulted in satisfactory clinical outcomes.

- Objectives: This study investigates whether the no-touch (NT) vein graft, at a mean time of 16 years, maintains a significantly higher patency rate than conventional (C) vein grafts and still has patency comparable to that of the left internal thoracic artery (LITA).Methods: A total of 156 patients accepted for coronary artery bypass grafting were randomly allocated to 1 of 3 groups. In the C group, the saphenous vein (SV) was stripped and distended. In the intermediate group, the SV was stripped but not distended. In the NT group, the SV was neither stripped nor distended, but rather harvested with a fat pedicle. This study is an angiographic follow-up of the C and NT groups, at a mean time of 16 years postoperatively.Results: Fifty-four patients were included (C group = 27; NT group = 27). In all, 72 and 75 vein grafts were completed in groups C and NT, respectively. Crude SV graft patency was 64% in the C group versus 83% in the NT group (P = .03), which was similar to the patency of the LITA (88%). The harvesting technique had a major impact on the patency with a hazard ratio for occlusion of 1.83 for the C group (P = .04).Conclusions: Harvesting the SV with the NT technique conferred, at a mean time of 16 years, a significantly higher patency than the conventional technique that was still comparable to that of the LITA.
