RESUMEN

Pulmonary sequestrations are rare congenital malformations. They are often located in the lower lobes, and they are supplied by an aberrant systemic vessel arising from the thoracic aorta or abdominal arteries. These pulmonary malformations are divided into intra- and extralobar sequestrations, depending on the respective lack or presence of an independent pleural covering. Pulmonary sequestration can be asymptomatic or lead to recurrent pulmonary infections. The goal of this study was to analyse the feasibility and safety of a hybrid sequential approach. We report a small series of intralobar pulmonary sequestrations, from November 2017 to December 2018, successfully treated with a hybrid minimally invasive approach consisting of endovascular embolization of the aberrant arterial branch followed by video-assisted thoracoscopic lobectomy the day after. Thoracic pain following endovascular embolization was noted in all cases. Patients were discharged early in the absence of major postoperative complications. Prolonged air leak was observed in only 1 case. Despite the presence of sequestration-related pulmonary inflammation, in our experience, hybrid treatment for intralobar pulmonary sequestration is a safe and reproducible approach in terms of postoperative complications and hospital stay.

RESUMEN

Obesity correlates with better outcomes in many neoplastic conditions. The aim of this study was to assess its role in the prognosis and morbidity of patients submitted to resection of lung oligometastases from colorectal cancer. Seventy-six patients undergoing a first pulmonary metastasectomy were retrospectively included in the study. Seventeen (22.3%) were obese (body mass index (BMI) >30 kg/m2). Assessed outcomes were overall survival, time to recurrence, and incidence of post-operative complications. Median follow-up was 33 months (IQR 16-53). At follow-up, 37 patients (48.6%) died, whereas 39 (51.4%) were alive. A significant difference was found in the 3-year overall survival (obese 80% vs. non-obese 56.8%, p = 0.035). Competing risk analysis shows that the cumulative incidence of recurrence was not different between the two groups. Multivariate analysis reveals that the number of metastases (p = 0.028), post-operative pneumonia (p = 0.042), and DFS (p = 0.007) were significant predictors of death. Competing risk regression shows that no independent risk factor for recurrence has been identified. The complication rate was not different between the two groups (17.6% vs. 13.6%, p = 0.70). Obesity is a positive prognostic factor for survival after pulmonary metastasectomy for colorectal cancer. Overweight patients do not experience more post-operative complications. Our results need to be confirmed by large multicenter studies.

RESUMEN

The aim of this study was to assess the prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) levels in patients undergoing resection of pulmonary oligometastases. A retrospective analysis on 141 patients undergoing a first pulmonary metastasectomy in a single center was carried out. Two distinct analysis were performed subdividing patients according to their NLR ratio and CRP level. The main outcomes were survival and time to recurrence. At completion of follow-up 74 patients were still alive (52.5%). Subdividing patients according to their NLR yielded a significant difference in five-year progression-free survival (PFS, NLR < 4:32% vs. NLR ≥ 4:18%, p = 0.01). When subdivided by their CRP levels, patients with preoperative CRP < 5 mg/L demonstrated higher values of five-year overall survival (OS, 57% vs. 34%, p = 0.006) and five-year PFS (35% vs. 22%, p = 0.04). At multivariate analysis, level of neutrophils (p = 0.009) and lung comorbidities (p = 0.021) were independent predictors of death, whereas preoperative CRP (p = 0.002), multiple metastases (p = 0.003) and presence of lung comorbidities (p = 0.001) were independent predictors of recurrence. NLR and CRP are important predictors of prognostic outcome in patients undergoing pulmonary metastasectomy.

RESUMEN

It is not clear as to which is the best treatment among surgery and stereotactic radiotherapy (SBRT) for lung oligometastases. A systematic review of literature with a priori selection criteria was conducted on articles on the treatment of pulmonary metastases with surgery or SBRT. Only original articles with a population of patients of more than 50 were selected. After final selection, 61 articles on surgical treatment and 18 on SBRT were included. No difference was encountered in short-term survival between pulmonary metastasectomy and SBRT. In the long-term surgery seems to guarantee better survival rates. Mortality and morbidity after treatment are 0-4.7% and 0-23% for surgery, and 0-2% and 4-31% for SBRT. Surgical metastasectomy remains the treatment of choice for pulmonary oligometastases.

RESUMEN

Open thoracotomy during pulmonary metastasectomy allows lung palpation and may discover unexpected further nodules. We assess the validity of intraoperative lung ultrasonography via thoracoscopy in identifying lung nodules. A first surgeon will perform an ultrasonographic investigation on the deflated lung by thoracoscopy. A second surgeon will then perform a manual exploration of the organ by thoracotomy. Data on number and localization of nodules will be matched and compared with final histology report. Sensitivity and specificity will be assessed. Concordance will be assessed with Cohen K test. Calculated sample size is 89 patients. This study might have an important role in shifting the surgical practice towards a less invasive approach, with consequent benefits for the patient. Protocol is registered on clinicaltrials.gov. Protocol registration number: NCT03864874.

RESUMEN

The object of our study is to show the causes leading to conversion, in order to observe the responsible variables and analyses if conversion influences the patient's outcome. Between January 2013 and December 2016, Udine Thoracic Department performed 180 video-assisted thoracoscopic surgery (VATS) lobectomies, and 24 cases were converted to thoracotomy due to an intra-operative complication such as arterial or venous bleeding, airway and other injuries. The VATS lobectomies' number increased over the three years: from 27 in 2013 to 55 in 2015 and 48 in 2016. While conversion's rate decreased from 33% in 2013 to 5.5% in 2015 and 10% in 2016. We performed a univariate and a multivariate analysis looking for the variables affecting the conversion rate. This was significantly related to intraoperative bleeding and airway injuries (P<0,001). Seventy-year older patients were not associated to a higher conversion rate, instead they showed an increased risk of post-operative complications (P<0,018, RR =1.8). We have focused our attention on all the variables leading to conversion and conditioning the patient's outcome in terms of post-operative complications and length of stay. The best strategy to face VATS complication is to prevent them. Young surgeons at the beginning of their learning curve should perform VATS lobectomies under close supervision of a skilled VATS surgeon. Moreover, conversion to open thoracotomy should be not considered a failure of VATS, but rather a procedure for patient's safety.

RESUMEN

OBJECTIVE: Cost-effectiveness of heart surgery for elderly patients is still poorly defined. We evaluated outcome, quality of life (QoL), cost, and cost-effectiveness of octogenarians undergoing cardiac surgery. METHODS: One thousand six hundred forty octogenarians undergoing various cardiac surgical procedures were prospectively studied between January 1998 and January 2009 and compared with similar patients aged 70 to 79 years. Several questionnaires were used to assess QoL. Six hundred age- and sex- matched healthy octogenarians and three hundred forty patients older than 80 years with medically treated valvular or coronary artery disease were healthy and unoperated control groups, respectively. In-hospital costs were obtained from the hospital's financial accounting department and cost-effectiveness was estimated and expressed as cost/QoL-adjusted life year (QALY) and cost-effectiveness ratio. RESULTS: Significant improvements occurred in elderly patients in Role Physical (P < .001), Bodily Pain (P < .001), General Health (P = .004), Social Functioning (P < .001), and Role Emotional (P < .001), whereas Physical Functioning, Vitality, and Mental Health did not change (difference not signficant). Total direct costs were $5293 higher in the octogenarian group. Cost-effectiveness was $1391/QALY for elderly surgical patients, $516/QALY for younger cardiac surgical patients (P < .001 vs elderly), $897/QALY for untreated control group, and $641/QALY for healthy control group (P < .001 vs elderly surgical patients). The cost-effectiveness ratio for octogenarians was $94,426. CONCLUSIONS: Our findings confirm that cardiac surgery in elderly patients remains controversial from a cost-effectiveness standpoint, making econometric analysis an important component for any future evaluation of novel cardiovascular therapies. Our findings need to be confirmed by additional multicenter studies.

RESUMEN

OBJECTIVE: The aim of this study was to determine the occurrence of patient-prosthesis mismatch (P-PM) after aortic valve replacement (AVR) with a small-size Cryolife O'Brien (CLOB) bioprosthesis and to evaluate its clinical and hemodynamic implications. METHODS: Sixty-two patients (mean age 70.9 +/- 5.2 years, 77.8% females), receiving a labeled 21-23 mm CLOB between 1993 and 2000, were retrospectively studied. Effective orifice area (EOA) was calculated by the continuity equation and then indexed to the patient's body surface area (BSA) to obtain the indexed EOA (EOAI). Based on previous observations a mismatch was defined as EOAI or= 0.8 cm/m2 showed an earlier concentric remodeling up to 1 year; no difference was demonstrated at later studies between groups. Survival and clinical status results were not affected by an EOAI

RESUMEN

BACKGROUND: The aim of this study was to evaluate the early and long-term outcomes in patients undergoing a Bentall procedure or its button modification for chronic aortic aneurysms with aortic valve incompetence. METHODS: Between January 1986 and January 2002, 65 patients (84% males, mean age 58.9 +/- 11 years) underwent aortic root replacement with a Bentall or a button-Bentall operation. Annuloaortic ectasia was the most frequent cause of aortic disease in this series (n = 37, 56.9%), followed by atherosclerotic aneurysms (n = 22, 33.9%), and post-stenotic dilation (n = 5, 7.7%). One patient (1.5%) underwent redo aortic root replacement,3 (4.6%) had a Marfan syndrome, and 6 (9.2%) underwent a concomitant replacement of the aortic arch. The duration of follow-up ranged from 2 to 192 months (mean 89.6 +/- 21.8 months). RESULTS: The 30-day mortality was 0%. Early non-fatal complications comprised: bleeding requiring surgical re-exploration (n = 1, 1.5%), low output syndrome (n = 1, 1.5%), acute renal insufficiency (n = 1, 1.5%), transient ischemic attack (n = 2, 3.1%), stroke (n = 1, 1.5%), and pulmonary insufficiency (n = 1, 1.5%). There was a late death due to a pulmonary neoplasm. The 16-year actuarial survival was 97 +/- 2% (hazard 0.02 +/- 0.02). No patient required reoperation. Furthermore, the long-term clinical follow-up was characterized by the complete absence of endocarditis, anticoagulant-related hemorrhage, valve thrombosis, and prosthetic failure. Finally, the NYHA functional status was significantly improved (1.1 +/- 0.50, p < 0.001 vs preoperatively). CONCLUSIONS: The late results of the Bentall and button-Bentall procedures were excellent. Our findings confirm that these techniques still constitute the gold standard in the surgical treatment of combined valve and ascending aorta pathologies.

RESUMEN

STUDY OBJECTIVES: The aim of this study was to evaluate the early and long-term outcomes in patients undergoing aortic root replacement (ARR) with the Bentall procedure. DESIGN: Retrospective study. SETTING: Cardiothoracic surgery unit. PATIENTS AND METHODS: Between January 1986 and January 2002, 72 patients (mean age 58.3 +/- 12.4 years, 81.9% males) underwent ARR by means of a Bentall operation. Annuloaortic ectasia was the most frequent cause of aortic disease in this series of patients (31 patients; 43.1%), followed by type A dissection (19 patients; 26.3%), atherosclerotic aneurysm (18 patients; 25.1%), and poststenotic dilatation (4 patients; 5.5%). Nine patients (12.5%) had Marfan syndrome, and 10 patients (13.8%) underwent a concomitant replacement of the aortic arch. Follow-up ranged from 2 to 192 months (mean [+/- SD], 86.6 +/- 23.8 months). RESULTS: The mean 30-day mortality rate was 5.5 +/- 2%. The mean early mortality rate was 21 +/- 4% and 0% (p < 0.001), respectively, in patients with and without dissecting aortic aneurysms. There were two late deaths that were due to a pulmonary neoplasm and a cerebrovascular accident. The mean 16-year survival rate was 91.7 +/- 3.2%. The mean hazard of freedom from death was constant beyond 3 years (8.5 +/- 3.5%). No patient required reoperation. Furthermore, the long-term clinical follow-up was marked by a complete absence of endocarditis, anticoagulant-related hemorrhage, valve thrombosis, and prosthesis failure. Finally, patients showed a significant improvement in mean New York Heart Association functional status (1.3 +/- 0.1; p < 0.001 [postoperatively vs preoperatively]). CONCLUSIONS: In our experience, the late results of the Bentall operation were satisfactory. Our findings confirm that this technique still represents the procedure of choice for ARR with coronary reimplantation.

RESUMEN

BACKGROUND: The St Jude Medical Regent is a new-generation mechanical heart valve that represents a design evolution of the St Jude Hemodynamic Plus Series (HP). The purpose of this study was to evaluate early "in vivo" hemodynamic performance of the Regent valve in patients with aortic stenosis. METHODS: Between March 2000 and December 2001, 32 patients (mean age 59.9 +/- 5.9,56.3% male) with pure aortic stenosis received a Regent mechanical prosthesis in the aortic position. Hemodynamic performance was assessed by Doppler echocardiography at discharge, two months, six months, and one year by calculating peak transprosthetic velocity (Vmax), mean (MG) and peak (PG) transprosthetic gradients, effective orifice area index (EOAI), left ventricular mass index (LVMI), and degree of aortic regurgitation. RESULTS: A significant reduction in mean and peak transaortic gradients (p < 0.001) and a significant increase in EOAI (p < 0.001) over time followed valve replacement, and a bivariate analysis of variance (ANOVA) failed to demonstrate statistical differences by valve size over time (p = ns). A significant reduction in left ventricular hypertrophy occurred over time (p < 0.001) in all valve sizes (p = ns between groups): baseline LVMI was 221 +/- 57 g/cm2; it decreased by 30 g/cm2 (p < 0.001) at discharge. LVMI decreased from 191 +/- 54 g/cm2 to 161 +/- 41 g/cm2 (p < 0.001) from discharge to two months. Further reductions were not significant. At the six-month follow-up no patient in our cohort exhibited moderate or severe aortic regurgitation at Doppler echocardiography. CONCLUSIONS: Early results with the St Jude Medical Regent valve have been satisfactory. Further assessments are necessary to confirm these results.

RESUMEN

OBJECTIVE: The purpose of this study was to assess the usefulness of transesophageal echocardiography to detect complications after a Cabrol procedure. METHODS: A total of 28 unselected patients (mean age 52.2 +/- 13.3 years; 86% male) who survived a Cabrol procedure were examined with transesophageal echocardiography at a mean of 64 +/- 32 postoperative months. Underlying diagnosis was Stanford type A dissection in 11% of the patients and nondissecting aneurysm in 89%. RESULTS: Periprosthetic jet as a result of a valve leakage was demonstrated in 3 patients (11%). In 1 patient (4%) with infected aortic graft, a fistula between the periprosthetic space and the right ventricle was detected, requiring reoperation. One patient (4%) showed a complete occlusion of the graft limb of the right coronary artery but did not need reoperation. An aneurysm of the periprosthetic space with perivalvular leakage and persistence of periprosthetic right atrial fistula was visualized in 3 patients (11%). CONCLUSIONS: Our findings encourage the use of transesophageal echocardiography for the follow-up of patients undergoing a Cabrol operation.

RESUMEN

AIM: The aim of this report is to summarize our experience with the Tirone David I technique over a 4-year period. METHODS: Since 1997 15 patients were operated on using this surgical procedure. Of the patients, nine were male (60%) and six (40%) female. Ages ranged from 23 to 75 years (mean 62.1+/-17.2 years). The underlying disease was chronic aneurysm of the ascending aorta or root in 13 (86.6%) and chronic dissection in two (13.4%). Four patients (26.6%) had skeletal manifestations of Marfan's syndrome. Additional cardiac procedures were performed in two patients (13.4%). Mean follow-up time was 26.6+/-11.2 months (range 7-50 months). RESULTS: There were no early deaths. Postoperative non-fatal complications occurred in two (13.3%) patients. There was no valve-related late death occurring 6 months after operation. Actuarial survival was 0.94+/-0.07 at 4 years; 4-year freedom from reoperation was 0.91+/-0.07. The probability of needing reoperation was 8+/-0.9%. There were no instances of infective endocarditis or thromboembolic complications. At the end of the follow-up period, trivial or no aortic regurgitation was demonstrated in 57.1%, mild in 42.9% and no patient had an insufficiency graded >/=moderate. Echocardiography showed early postoperative reduction in left ventricular end-systolic and end-diastolic dimensions, which was maintained at follow-up controls. CONCLUSIONS: The Tirone David I procedure showed good early results, which encourage further use of this type of repair. However, further larger studies and long-term results are necessary for a definite judgment on this operative method.

RESUMEN

BACKGROUND: Little information exists regarding the long-term results of the Cabrol technique. This study aimed at exploring, over a 16-year period, the results of aortic root replacements employing this procedure. METHODS: Between 1986 and 2002 forty-five patients (mean age 58.7 +/- 13.8 years old, 84.4% male) underwent a Cabrol procedure. Aortic dissection was the most frequent cause of aortic disease in this series (n = 17), followed by annuloaortic ectasia (n = 10), atherosclerotic aneurysm (n = 5) and poststenotic dilatation (n = 5). Six patients (13.4%) had undergone a previous aortic operation, 8 (17.7%) had a Marfan syndrome and five (11.1%) underwent concomitant arch replacement. Mean clinical follow-up was 87.3 +/- 24.3 months. Twenty-eight patients (93.3% of survivors) had a transesophageal echocardiography (TEE) performed at a mean of 64 +/- 32 months postoperatively. RESULTS: Early mortality was 20%. It was 9.1% for patients with an ascending aortic aneurysm and 41.2% for dissections (p = 0.026). Independent multivariate predictors of early mortality were: aortic dissection (p = 0.009), emergency operation (p < 0.001), operative year (p = 0.02), cross-clamp time (p = 0.001), and CPB duration (p < 0.001). Actuarial survival was 0.77 +/- 0.06, 0.72 +/- 0.06, 0.59 +/- 0.04 and 0.59 +/- 0.04 at 1, 5, 10, and 16 years, respectively. Multivariate analysis revealed age (p = 0.007), cross-clamp time (p = 0.0006) and CPB duration (p = 0.009) as strong predictors of poor late survival. A periprosthetic jet with significant valve regurgitation was detected by TEE in 3 patients. In one of them, an infected periprosthetic space-right ventricular fistula was demonstrated requiring reoperation. Altogether, freedom from reoperation and endocarditis at 16 years was 0.97 +/- 0.02 and 0.94 +/- 0.03, respectively. CONCLUSIONS: The Cabrol technique demonstrated a nonnegligible incidence of early and long-term complications. It should be rarely used and only when a "button" technique is not feasible.
