ABSTRACT

Resumen Introducción: El hemotórax masivo (HM) se puede definir como el acúmulo súbito de ≥ 1.500 ml de sangre en la cavidad pleural o débito ≥ 200 ml/h de sangre en 3-4 h por pleurotomía; es considerada una complicación traumática grave. Objetivo: Describir las características clínicas, índices de gravedad de traumatismo (IGT), morbilidad y variables asociadas a mortalidad en pacientes con hemotórax masivo por traumatismo torácico operados (HMTT). Materiales y Método: Estudio analítico longitudinal. Período enero de 1981 a diciembre de 2018. Revisión prospectiva de base de datos, protocolos quirúrgicos y fichas clínicas. Descripción de características de HMTT. Se calcularon IGT: Injury Severity Score (ISS), Revised Trauma Score (RTS-T), Trauma Injury Severity Score (TRISS). Para mortalidad se realizó análisis univariado con cálculo de Odds Ratio. Resultados: Total 4.306 traumatismos torácicos (TT), HMTT 119 (2,8%). Hombres 112 (94,1%), edad promedio 32 ± 13,2 años, 91 (76,5%) pacientes presentaron TT aislado, 28 (23,5%) asociado a lesiones extratorácicas, de estos, 23 (19,3%) fueron politraumatismos. Fueron traumatismos penetrantes 102 (85,7%). El HMTT se atribuyó principalmente a: lesión de pared en 38 (31,9%) y lesión pulmonar en 29 (24,4%). De las cirugías torácicas: 87 (73,1%) fueron urgentes (≤ 4 h), 10 (8,4%) precoces (> 4-24 h) y 22 (18,5%) diferidas (> 24 h). Hospitalización postoperatoria promedio 7,9 ± 6,4 días. Según IGT: ISS promedio 17,4 ± 9,6, RTS-T promedio 10,2 ± 2,7, TRISS promedio 12,7. Morbilidad 46 (38,7%) y mortalidad 15 (12,6%). Discusión: Los HMTT se atribuyeron principalmente a lesiones de pared y lesión pulmonar. En la mayoría se requirió cirugía torácica de urgencia. La mortalidad observada es semejante a la esperada según IGT. Existen variables asociadas a mayor mortalidad.


Introduction: Massive hemothorax (MH) can be defined as the sudden accumulation of ≥ 1500 ml of blood in the pleural cavity or debit ≥ 200 ml/h in 3-4 hours through pleurostomy, and it is considered a serious complication. Aim: To describe features, trauma severity indexes (TSI), morbidity and variables associated with mortality in patients with traumatic MH who required surgical treatment. Materials and Method: analytical longitudinal study. Period January 1981 to December 2018. Database, surgical protocols, medical records review. Description of MH characteristics. The following TSI were calculated: Injury Severity Score (ISS), Revised Trauma Score (RTS-T), Trauma Injury Severity Score (TRISS). An Odds Ratio univariate analysis was used for mortality. Results: Total 4306 TT, operated MH 119 (2.8%). Men were 112 (94.1%), average age 32 ± 13.2 years, 91 (76.5%) had isolated TT, 28 (23.5%) were associated with extrathoracic injuries and of these 23 (19.3%) were polytraumatized patients. Penetrating TT was 102 (85.7%). MH was mainly attributed to: chest wall injury in 38 (31.9%), pulmonary lacerations 29 (24.4%). Of the thoracic surgeries: 87 (73.1%) were urgent (≤ 4 h), 10 (8.4%) early (> 4-24 h) and 22 (18.5%) deferred (> 24 h). Average post operatory stay (days): 7.9 ± 6.4 According to TSI: average ISS 17.4 ± 9.6; RTS-T average 10.2 ± 2.7; TRISS average 12.7. Morbidity 46 (38.7%). Mortality 15 (12.6%). Discussion: MH is mainly attributed to chest wall injuries and pulmonary lacerations. Most of HM required urgent thoracic surgery. The observed mortality is similar to that expected one by TSI. There are variables associated with higher mortality in MH.

ABSTRACT

Background: Lungs are the second location in frequency of hydatidosis or cystic echinococcosis. Aim: To characterize the clinical manifestations, diagnosis, findings and treatment of patients hospitalized for a pulmonary hydatid cyst (PHC). Materials and Methods: Review of databases, medical records, operation notes and death certificates of patients admitted to a Chilean regional hospital with a PHC. Results: Four hundred twenty-nine cases were identified and complete data was obtained from 368 patients aged 34 ± 19 years, 224 (60,9%)men. The most common clinical manifestations were cough in 269 (73%) and chest pain in 217 (59%). The most frequent locations were the right lung in 210 (57%) and lower lobes in 218 (59%). One hundred eighty-seven cysts (51%) were complicated. Conservative surgery (cystectomy) was performed in 308 (84%). Postoperative morbidity was observed in 77 (21%) and mortality in 6 (2%) patients. Recurrence was observed in 28 (8%) patients. There was a significant reduction in morbidity, mortality, reoperations, and postoperative days over time. Conclusions: In these patients, pulmonary hydatidosis was diagnosed mainly during working ages and half of patients had a complicated cyst.

ABSTRACT

Background: Primary cardiac tumors have a low incidence, and their presentation form and clinical course are not well known. Aim: To describe the characteristics, treatment, follow up and survival of patients with primary cardiac tumors (PCT). Material and Methods: Review of all surgical procedures for PCT performed between 1984 and 2019 in a regional general hospital. The information was obtained from surgical protocols, surgical and pathology databases, medical records and registries of the Chilean National Identification Service. The clinical features of patients, immediate and long term outcomes are described. Results: Seventy-two surgical procedures for PCT were reviewed. Patients' age was 55 ± 15 years and 60% were women. The most common histological types were myxoma in 49 patients (68%), papillary fibroelastoma in 13 (18%) and sarcoma in 6 (8.3%). Forty-nine (68.1%) were symptomatic and all tumors were found on echocardiography. Fifty-one (71%) were in the left atrium, 10 (14%) in the aortic valve and eight (11%) in the right atrium. The surgical procedures were tumor resection in 48 patients (67%) and resection and repair with patch in 23 (32%). Mean postoperative stay was 6.6 ± 4.4 days, eight patients (11%) had complications and no patient died in the immediate postoperative period. Long term survival was higher in patients with benign PCT as compared with those with malignant tumors. Conclusions: Most PCTs in this group of patients were benign neoplasms and the most common tumors were myxomas. The main diagnostic method is echocardiography and the prognosis of surgical treatment is excellent when the tumors are benign. (Rev Med Chile 2020; 148: 327-335)

MATERIALES Y MÉTODO: Hombre de 52 años, con antecedente de quiste hidatídico cardiaco operado hace 27 años, insuficiencia cardiaca y enfermedad coronaria. Presentó disnea progresiva de un año de evolución. Estudio con radiografía de tórax, ecocardiografía y tomografía computada que mostró imagen compatible con hidatidosis cardiaca recidivada en el ventrículo izquierdo, arteria pulmonar e hilio pulmonar izquierdo, rodeando por completo el tronco coronario común izquierdo y parte proximal de la arteria descendente anterior. Se constató fracción de eyección de ventrículo izquierdo aproximadamente de 30%. No se encontró evidencia de enfermedad hidatídica extracardiaca. Se decidió tratamiento quirúrgico. Se abordó por esternotomía media y en circulación extracorpórea, se observaron lesiones compatibles con quiste hidatídico multiloculado de ubicación miocárdica en ventrículo izquierdo, con incontables vesículas hijas. Se realizó quistectomía más periquistectomía hidatídica sin incidentes. Presentó hemorragia postoperatoria por lo que requirió reintervención quirúrgica precoz. Evolucionó favorablemente y fue dado de alta sin complicaciones. A seis años de seguimiento se encuentra asintomático, sin evidencia tomográfica y ecocardiográfica de recidiva. DISCUSIÓN: La hidatidosis es una zoonosis endémica en Chile. La ubicación cardiaca es infrecuente, correspondiendo al 0,5 al 2% de los casos. Suele asociarse a la presencia de quistes extracardiacos. La ubicación más frecuente es la pared libre del ventrículo izquierdo a nivel intramiocárdico. El tratamiento médico suele ser insuficiente, por lo que se recomienda la resección quirúrgica.


INTRODUCTION: Cardiac hydatid cyst is a rare disease caused by Echinococcus granulosus arrival of the coronary circulation. MATERIAL AND METHOD: 52 years old man with a history of cardiac hydatid cyst operated 27 years ago, heart failure and coronary artery disease. He presented with a history of one year of progressive dyspnoea. Study with chest radiography, echocardiography and computed tomography showed an image compatible with cardiac hydatid disease recurrence in relation to the left ventricle, pulmonary artery and anterior descending artery. Ejection fraction of the left ventricle was approximately 30%. No evidence of extracardiac hydatid disease was found and surgical treatment was decided. Addressed by median sternotomy and extracorporeal circulation, a multiloculated myocardial hydatid cyst, with hundreds of daughter vesicles of different size was found. Pericystectomy of the hydatid cyst was performed without incident. The patient presented postoperative bleeding which required early reoperation. Posteriorly, was discharged without complications. DISCUSSION: Hydatid disease is an endemic zoonosis in Chile. Heart location is infrecuent and correspond to 0.5 to 2% of the cases, usually associated with the presence of extracardiac cysts. The most common location is the free wall of the left ventricle at intramyocardial level. Medical treatment is often inadequate and surgical resection is recommended.

ABSTRACT

Background: Exclusive coronary revascularization with both mammary arteries could result in lower rates of adverse events in the long term. Aim: To describe the five-year evolution of a cohort of patients operated on with this technique. Material and Methods: Follow up analyzing survival of 73 patients aged 59 ± 9 years (82% men) who underwent exclusive coronary surgery with two mammary arteries between December 1,2010 and April 12,2017. We studied their clinical characteristics, surgical results, operative morbidity and mortality and adverse events up to June 30, 2018. Results: Six patients had two-vessel lesions and 67 three-vessel lesions. The operative risk calculated by additive and logistic EuroSCORE was 2.5 and 2.3%, respectively. A mean of 3.75 anastomoses /patient were performed, 116 with left mammary artery (73 to the anterior descending artery, 38 to a diagonal artery and 5 for other objectives) and 158 with right mammary artery (69 to a first marginal artery, 23 to a second marginal artery and 64 to posterior descending artery). There was one case of mediastinitis and one (1.5%) patient died. The mean follow-up was 64.6 ± 23.7 months. The 5-year survival was 90.4%. Conclusions: Coronary revascularization with two exclusive mammary arteries allowed a complete revascularization of the heart with a low rate of complications and adverse effects at five years.

ABSTRACT

INTRODUCCIÓN: El traumatismo torácico (TT) es una causa importante de morbilidad y mortalidad, presente en el 25-50% de la mortalidad por traumatismo. El TT contuso (TTC) es el tipo más frecuente de TT según las diferentes publicaciones internacionales. OBJETIVO: Nuestros objetivos son describir las características, tratamientos, morbilidad y mortalidad en pacientes hospitalizados por TTC en nuestra institución. MATERIAL Y MÉTODOS: Estudio descriptivo transversal desde enero-1981 a diciembre-2017. Revisión de una base de datos prospectiva, protocolos quirúrgicos y fichas clínicas. Se describen y comparan las características de los TTC. Se calcularon índices de gravedad de traumatismo (IGT): Injury Severity Score (ISS), Revised Trauma Score (RTS-T), Trauma Injury Severity Score (TRISS). RESULTADOS: Total 4.163 pacientes hospitalizados por TT, 1.719 (41,3%) TTC. Hombres 1.327 (77,2%), edad promedio 46,7±18,8 años. Se consideró TT aislado 966 (56,2%), asociado a lesiones extratorácicas 753 (43,8%) y de estos 508 (29,6%) eran politraumatizados. Mecanismo: Accidente de tránsito 838 (48,7%), caída de altura 279 (16,2%). Lesiones y hallazgos torácicos: fractura costal 1.294 (75,3%), neumotórax 752 (43,1%). Tratamiento: médico 874 (50,8%), pleurotomía 704 (41%) y cirugía torácica 141 (8,2%). Período de hospitalización 9,2 ± 9,5 días. Según IGT: ISS promedio 14,1 ± 11,1, RTS-Tpromedio 11,5 ± 1,5, TRISS promedio 6,6. Morbilidad en 297 (17,3%), mortalidad en 68 (4%). DISCUSIÓN: La causa principal de los TTC fue el accidente de tránsito. La fractura costal correspondió a la lesión torácica más frecuente. La mayoría requirió solo tratamiento médico. La mortalidad fue menor a la esperada según IGT.


BACKGROUND: Thoracic trauma (TT) is a major cause of morbimortality, involved in 25-50% of trauma deaths. Internationally, blunt thoracic trauma (BTT) is the most frequent type of TT. OBJECTIVE: Our objectives are to describe the clinical characteristics, treatments, morbidity and mortality in patients hospitalized by blunt thoracic trauma (BTT) in our institution. MATERIAL AND METHODS: Cross-sectional descriptive study from january-1981 to december-2017. Prospective database review, surgical protocols and clinical files. The characteristics of the BTT are described and compared. The following trauma severity indices (TSI) were calculated: Injury Severity Score (ISS), Revised Trauma Score (RTS-T) and Trauma Injury Severity Score (TRISS). RESULTS: 4,163 patients were hospitalized because of TT, 1.719 (41.3%) of them with BTT. 1,327 (77.2%)patients were men, average age 46.7 ± 18.8 years-old. We considered isolated TT 966 (56.2%), associated with extrathoracic lesions 753 (43,8%) and 508 (29.6%)with polytraumatism. Mechanism: Traffic accident 838 (48.7%), fall down from a height 279 (16.2%). Lesions and intrathoracic findings: rib fracture 1.294 (75.3%), pneumothorax 752 (43.7%). Treatment: Medical 876 (50.8%), pleurotomy 704 (41%) and thoracic surgery 141 (8.2%). Average hospitalized period 9.2 ± 9.5 days. According to TSI: ISS average 14.1 ± 11.1, RTS-T average 11.5 ± 1.5, TRISS average 6.6. Morbidity in 297 (17.3%), mortality in 68 (4%). DISCUSSION: The TTC was mainly attributed to the traffic accident. Rib fracture was the most common chest injury. The majority of patients required only medical treatment. Mortality was lower than expected according to TSI.

ABSTRACT

Resumen Introducción: El doble arco aórtico (DAA) es una malformación cardiovascular infrecuente caracterizada por la persistencia de ambos arcos aórticos posterior al nacimiento. Puede presentarse con rama derecha dominante (70-73%), izquierda o simétrica. Su forma anatómica produce compresión de estructuras mediastínicas como la tráquea y esófago. Caso clínico: Lactante menor hombre de 3 meses, con antecedente de estridor desde nacimiento. Ingresó a nuestro centro por neumonía grave con necesidad de ventilación mecánica prolongada. Evaluado por otorrinolaringología, se realizó revisión de vía aérea, observando estenosis en los últimos 5 anillos traqueales con colapso dinámico de la tráquea. La tomografía computada de tórax demostró DAA completo con emergencias de troncos supraaórticos de ambos arcos de forma simétrica. Se decidió tratamiento quirúrgico a la brevedad. Se abordó por toracotomía anterolateral izquierda, se realizó control vascular y sección del arco aórtico izquierdo distal a emergencia de subclavia, con plastía de aorta y arteria subclavia izquierda, liberado el arco aórtico se realizó pexia y disección de tejido fibrótico que rodeaba tráquea y esófago. Paciente evolucionó favorablemente, con resolución de cuadro respiratorio y ausencia estridor. Fibrobroncoscopía posoperatoria no observó compresión traqueal. El alta hospitalaria fue al 14° día posoperatorio. Actualmente, a seis meses de seguimiento, se encuentra asintomático respiratorio y cardiovascular. Discusión: El DAA puede afectar al 0,03% de la población pediátrica. Usualmente es sintomático con manifestaciones obstructivas como estridor o disfagia por compresión de estructuras mediastínicas, por lo que requiere alta sospecha clínica para su confirmación imagenológica y posterior tratamiento quirúrgico.


Introduction: The double aortic arch (DAA) is an uncommon cardiovascular malformation, characterized by the persistence of both aortic arches after birth. It can be presented with right dominant branch (70-73%), left or symmetrical. It's anatomical shape produces compression of mediastinal structures such as the trachea and esophagus. Clinic case: Infant man 3 months old, with a history of stridor since birth. He was admitted to our center due to severe pneumonia with the need for prolonged mechanical ventilation. Evaluated by otorhinolaryngology, who performed airway revision observing stenosis in the last 5 tracheal rings with dynamic trachea collapse. Chest computed tomography showed complete DAA with emergence of supraaortic trunks of both arches symmetrically. Surgical treatment was decided as soon as possible. It was approached by left anterolateral thoracotomy, vascular control and left aortic arch section distal to subclavian emergency was performed, with aortic and left subclavian artery plasty, aortic arch was released to perform pexia and dissection of fibrotic tissue surrounding the trachea and esophagus. Patient evolved favorably, with resolution of respiratory symptoms and absence of stridor. Postoperative fiberoptic bronchoscopy did not observe tracheal compression. He was discharged on the 14th postoperative day. Currently at six months of follow-up, he is asymptomatic respiratory and cardiovascular. Discussion: AAD can affect 0.03% of the pediatric population. It is usually symptomatic with obstructive manifestations such as stridor or dysphagia due to compression of mediastinal structures, which requires high clinical suspicion for its imaging confirmation and subsequent surgical treatment.

ABSTRACT

Embolic stroke secondary to cardiac tumors is uncommon. However, 25-30% of cardiac tumors may cause systemic emboli. We report a 29-year-old male consulting for a sudden episode of aphasia and right hemiparesis, compatible with infarct of the left middle cerebral artery territory. Transthoracic echocardiography reported an ovoid tumor of 8 × 7 × 7 mm in relation to the sub valvular apparatus of the mitral valve. After neurologic stabilization, surgical treatment was performed. Approached by median sternotomy and in cardiopulmonary bypass, the mitral valve was explored. A macroscopic tumor consistent with a papillary fibroelastoma curled in sub valvular chordae was found. It was deployed and resected from its base, while the anterior mitral leaflet was preserved intact. Histopathological examination confirmed the intraoperative macroscopic diagnosis. The patient recovered uneventfully postoperatively and was discharged on the fifth day after surgery. He currently is in functional capacity I without cardiovascular symptoms at five years follow-up.

ABSTRACT

Background: Coronary artery bypass grafting (CABG) is the best treatment for a large group of patients with coronary artery disease. Aim: To describe early and late results of patients treated with CABG at our Center. Patients and Methods: Revision of data bases, surgical protocols and clinical registers of patients operated between January 2006 and December 2008. Results: Of 1.003 cardiac surgeries performed during the period, 658 corresponded to isolated CABG (78% in men). The median age of patients was 62 years. Left common coronary artery lesions was found in 135 cases (20%), 555 patients (84%) had hypertension and 231 (35%) were diabetics. Four-hundred thirty (65%) had stable angina and 211 (32%) had a recent myocardial infarction. Twenty-two had left ventricular ejection fraction < 30%. In 248 (38%), a low Additive EuroSCORE risk was found. Emergency surgery was required in 36 (6%) patients. Use of extracorporeal circulation was required in 466 patients (71%). Within 30 days of surgery, complications were recorded in 105 patients (16%) (15 (2%) stroke, 14 (2%) myocardial infarction, 7 (1%) mediastinitis, and in 14 (2%) a reoperation for bleeding). Thirteen patients died (2%). Among the 303 patients with stable angina and preserved left ventricular function, two died (0,7%). Survival at 1, 3 and 5 years was 97,4%, 93,8% y 90,9% respectively. Major adverse cardiac and cerebrovascular events at five years occurred in 20%, stroke in 4%, myocardial infarction in 3% and reintervention in 2%. Seven percent of patients had recurrence of angina. Conclusions: We describe a heterogeneous series of patients. The immediate and late results are comparable with international communications.

ABSTRACT

Background: Thymectomy improves clinical outcomes and decreases the need for medical treatment in patients with myasthenia gravis (MG). Aim: To describe the immediate and long-term results of extended transsternal thymectomy (ETT) in patients with MG. Material and Methods: A review of databases, surgical protocols, clinical records and interviews of patients subjected to extended transsternal thymectomy for MG between 1990 and 2016. Perioperative clinical characteristics, anticholinesterase treatment, immediate and remote surgical results were analyzed and patients were followed from one to 10years. Results: We studied 58 patients aged 35 ± 14years (72%) women. In the preoperative period, according to Osserman classification, nine patients (15,5%) were in grade I, eight (13,8%) in grade IIA 8 and 40 (69%) in grade IIB. The pathological study of the surgical piece showed thymic hyperplasia in 39 cases (67,2%). Four patients had postoperative complications but none died. In the Follow-up at 1, 3, 5, 8 and 10years the Masaoka palliation rate was 71.7, 77.5, 67.7, 70.0 and 70,6% respectively. The figures for remission rate were 13.0, 15.0,19.4, 35.0 and 35,3% respectively. The figures for Zielinski positive results were 79.6, 87.5, 87.1, 90.0 and 82,4% respectively. The DeFilippi score improved by 80.4, 87.5, 87.1, 90.0 and 82.4% respectively. The Myasthenia Gravis Foundation of America Post-Intervention State improved by 67.4, 77.5, 77.5, 75.0 and 70,6% respectively. Mean Myasthenia Gravis Activities of daily living (MGADL) and Myasthenia Gravis Quality of life scale 15 (MGQOL 15) were 1.65 and 6.31 respectively. Conclusions: In selected patients with MG, extended transsternal thymectomy in MG has good immediate and long-term results.

ABSTRACT

Background: Trauma is the leading cause of death in young patients and thoracic trauma (TT) is responsible for 25-35% of trauma deaths. Aim: To describe and compare features, trauma severity indexes and morbidity of patients admitted for TT in the past three decades. Material and Methods: Review of a TT database, operative notes and medical records of patients. These were separated by decade of admission (1981-1990, 1991-2000, 2001-2010). TT characteristics were compared. Injury Severity Score (ISS), Revised Trauma Score (RTS-T) and Trauma Injury Severity Score (TRISS) were calculated. Results: A total of 3,068 TT were reviewed. In the 1981-1990 period, 604 cases of TT were registered (19.7%), in the 1991-2000 period, 1,070 cases (34.9%) and in the 2001-2010 period, 1,394 cases (45.4%) (p < 0.05). The ages of patients in each of these periods were 34.9 ± 15.5, 33.9 ± 16.2 and 35.7 ± 18.2 years respectively (p < 0.05). The proportion of patients aged 65 years or more were 6.6, 7.7 and 10.1% respectively, the proportion of females was 6.1, 9.4 and 12.0%, respectively. The causing agents per decade were knife wounds in 51.5, 61.1 and 60.0% of cases respectively, firearms in 2.5, 3.3 and 5.0% of cases respectively, multiple trauma in 13.9, 14.5 and 9.0% respectively and morbidity in 18.7, 19.7 and 11.7%, respectively. The ISS per decade was 11.9 ± 6.5, 12.9 ± 6.9 and 10.4 ± 6.8 respectively. No significant difference were found in mortality (1.5, 3.0, 2.0% respectively) or TRISS score (2.7, 3.2 and 3.8% respectively). Conclusions: An increase in the number of hospital admission for TT has occurred in the last three decades, with an increase in the proportion of admissions of subjects aged 65 years or more, females and with firearm injuries.

ABSTRACT

Penetrating aortic ulcer (PAU) is an ulceration of an atherosclerotic plaque which disrupts the aortic internal elastic lamina and that can evolve to an intramural hematoma (IH), aortic dissection or aortic rupture. We report two cases with PAU. A 73 year-old woman with a history of hypertension, presented with acute chest pain of three days of evolution and a hypertensive emergency. An electrocardiogram showed ST-segment elevation and elevated cardiac enzymes. Computed tomography (CT) scans showed an acute ascending aortic mural hematoma secondary to PAU and hemopericardium. Replacement of ascending aorta was performed with a vascular prosthesis with extracorporeal circulation (ECC). PAU and IH were confirmed by histopathology. A 62-year old woman with a history of hypertension, diabetes and chronic obstructive pulmonary disease, consulted for abdominal pain of two days of evolution. A thoracic-abdominal CT scan visualized an uncomplicated PAU and an abdominal aortic aneurysm. Because of abdominal pain and signs of peritoneal irritation, an exploratory laparotomy was performed finding a typhlitis. Resection and ileo-ascendo-anastomosis were performed. A new CT scan showed PAU with high risk of rupture without a clinical acute aortic syndrome. The patient was operated replacing the ascending aorta with a vascular prosthesis using ECC. Three PAU were found. Histopathology confirmed the diagnosis. Both patients evolved without postoperative complications.

ABSTRACT

Surgery of the ascending aorta and its arc with extracorporeal circulation require an arterial cannulation that assures and adequate systemic circulation and reduces the risk of neurological complications. A peripheral cannulation such as the femoral artery, a central extra-thoracic approach such as axillary, subclavian or carotid arteries or a central intra-thoracic approach such as aorta and innominate arteries, are valid alternatives. Innominate artery cannulation can be carried out without the need of a second incision. It is an easily accessible and large bore vessel. It allows an anterograde brain and visceral flow. In cases of aortic arch surgery, the clamping of the artery in its origin, allows a selective anterograde brain perfusion. The surgical technique for innominate artery cannulation is herein described.


La cirugía de la aorta ascendente y cayado con circulación extra corpórea requiere de una canulación arterial que permita asegurar una perfusión sistémica adecuada y disminuir las complicaciones neurológicas. El sitio ideal de canulación es aún un tema de discusión entre los cirujanos. Entre las alternativas de abordaje están la canulación periférica (arteria femoral), la canulación central extratorácica (arterias axilar, subclavia o carótidas) y la canulación central intratorácica (aorta, arteria innominada). La canulación de la arteria innominada es una técnica que se puede realizar sin necesidad de una segunda incisión, es un vaso de fácil abordaje y habitualmente de gran calibre. Permite entregar un flujo cerebral y visceral anterógrado y, en caso de cirugía sobre el cayado, el pinzamiento de la arteria a nivel de su origen permite entregar una perfusión cerebral selectiva anterógrada. Se describen la técnica quirúrgica y los reparos operatorios que nos parecen importantes en su realización.

ABSTRACT

Background: Coronary artery bypass graft surgery without cardiopulmonary bypass (CPB) is an alternative technique for myocardial revascularization. Aim: To report the early results and 4 yearsfollow up ofthefirst 220 cases operated with this technique. Patients and Methods: Descriptive study of 220 patients aged 60.6 ±8.8 years (171 men) undergoing off-pump coronary surgery between 2004 and 2008. One hundred seventy six (80%) patients had hypertension, 59 (26.8%) had diabetes, 86 (39%) dyslipidemia and 85 (38.6%) were smokers. One hundred forty one patients (64.1%) had stable angina. Fiftyfour (24.5%) had a recent infarction (< 90 days) and 46 (20.9%) had a previous angioplasty. Ejection fraction was < 30% in 9 (4.1%), 30% - 50% in 57 (25.9%) and > 50% in 154 (70%). Additive and logistic EuroSCORE were 3.32 and 3.55% respectively. We studied the complications and mortality at 30 days. Long term follow up (late mortality and major cardiovascular events such as myocardial infarction (MI) stroke and re-intervention were assessed using data of medical records and National Identification Registry Service until June 30, 2011. Results: A total of 481 bypasses were performed (2.27 bypassesl patient). There were 4 (1.8%) conversions and no incomplete revascularization. Post-Operative complications occurred in 42 patients. Eight neurological (five strokes), five renal (two required dialysis), 16 cardiovascular (four myocardial infarctions), 15 surgical and 11 infections. Three patients died (1.36%). After a follow up of 4.26 ± 1.02 years, overall survival was 92.3%, and survival free of myocardial infarction, stroke or re - intervention was 96.8%, 96.8% and 95.9% respectively. Conclusions: Off-pump coronary surgery in selected patients has immediate and late results comparable to traditional surgery.
