Surgical treatment of Stanford type A aortic dissection after coronary artery stenting / 中国胸心血管外科临床杂志

@#Objective    To retrospectively analyze the surgical treatment of Stanford type A aortic dissection after coronary artery stenting, and to explore the surgical techniques and surgical indications. Methods    Clinical data of 1 246 consecutive patients who underwent operations on Stanford type A aortic dissection from April 2016 to July 2019 in Beijing Anzhen Hospital were retrospectively analyzed. Patients with Stanford type A aortic dissection after coronary artery stenting were enrolled. Results    Finally 19 patients were collected, including 16 males and 3 females with an average age of 54±7 years ranging from 35 to 66 years. There were 11 patients in acute phase, 15 patients with AC (DeBakey Ⅰ) type and 4 patients with AS (DeBakey Ⅱ) type. In AC type, there were 10 patients receiving Sun's surgery and 5 patients partial arch replacement. Meanwhile, coronary artery bypass grafting was performed in 7 patients and mitral valve replacement in 1 patient. Stents were removed from the right coronary artery in 4 patients. In this group, 1 patient died of multiple organ failure in hospital after operation combined with malperfusion of viscera. Eighteen patients recovered after treatment and were discharged from hospital. The patients were followed up for 30 (18-56) months. One patient underwent aortic pseudoaneurysm resection, one thoracic endovascular aortic repair, one emergency percutaneous coronary intervention due to left main artery stent occlusion, and one underwent femoral artery bypass due to iliac artery occlusion. Conclusion    Iatrogenic aortic dissection has a high probability of coronary artery bypass grafting at the same time in patients with Stanford type A aortic dissection after coronary artery stenting. Complicated type A aortic dissection after percutaneous coronary intervention should be treated with surgery aggressively.

Malrotation in the adult, a forgotten Etiology of Partial Gut Obstruction: A report of two cases

@#Ninety percent of cases of malrotation have shown signs and symptoms of intestinal obstruction by the first year of life. It is thus an often-overlooked etiology in adult patients. Evidence-based recommendations are also limited because of the paucity of cases. This paper discusses the two cases of malrotation from diagnosis to surgical management at a tertiary academic hospital. Both are previously well adult male patients with virgin abdomen who presented with vomiting and signs of intestinal obstruction. During medical decompression, CT scan with triple contrast clinched the diagnosis of malrotation for which Ladd's procedure was done, with no operative complications. The authors' experience and previous literature support early decompression, imaging, and surgery for all cases of malrotation regardless of severity of symptoms.

Surgical treatment of Stanford A intramural hematoma / 中华胸心血管外科杂志

Objective@#To summarize experience and result in surgical treatment of Stanford type A intramural hematoma.@*Methods@#60 patients with Stanford type A intramural hematoma were operated from February 2015 to August 2017. Surgery was indicated in complicated cases with penetrating ulcer or ulcer-like projection in ascending aorta, maximum aorta diameter≥50 mm, progressive maximum aortic wall thickness≥10 mm, pericardial or pleural effusion, persistent or recurrent pain. Aortic valve regurgitation. In our group, 46 patients recieved ascending aorta replacement+ Sun' s procedure. 6 patients recieved Bentall+ Sun' s procedure. 4 patients recieved asceding aorta+ hemiarch replacement. 2 patients recieved Bentall+ hemiarch replacement. 2 patients recieved asceding aorta replacement.@*Results@#In the whole group, there was 1(1.7%)operative death because of multiple organ failure after operation. Hyoxemiaoccured in 5(8.3%) patients, 2(3.3%) patients occurred new renal failure and required CRRT treatment, cerebrovascular complication occurred in 1 (1.7%)patient, re-sternotomy due to bleeeding occured in 1 (1.7%)patient and paraplegia occured in 1(1.7%) patient after operation. but they recoved quickly after proper treatment. During follow up period, there were 4 cases need reintervention, including TEVAR for type B dissection at 3 months and distal stent-graft new entry at 1 year. Two other reinterventions were performed for endoleak by interventional occlusion. During the follow-up, hematoma absorption rates after treatment 1、3 and 6 months were 68.6%, 84.7% and 94.8%.@*Conclusion@#Given the dynamic evolution of acute type A IMH pre-operative accurate indications and the proper surgical strategy maybe the keys for success.

Sun' s procedure with preservation of autologous brachiocephalic vessels for chronic type A aortic dissection / 中华胸心血管外科杂志

Objective To summarize the clinical outcomes and surgical indications for chronic type A aortic dissection (CTAD) by using Sun's procedure with preservation of autologous brachiocephalic vessels.Methods From September 2010 to December 2013, 23 patients with CTAD underwent Sun's procedure with preservation of autologous brachiocephalic vessels under moderate hypothermic circulatory arrest combined with selective cerebral perfusion in our center .The data was collected and analysed retrospectively.There were 20 males and 3 females patients with a mean age of(49.91 ±10.05) years.Preopera-tive comorbidities included Marfan syndrome in 1 patient, isolated left vertebral artery in 1, hypertension in 19, coronary artery disease in 2, heart dysfunction in 1, renal insufficiency in 1, mitral regurgitation in 1, and pulmonary infection in 1.Previous operation history included thoracic endovascular aortic repair in 3, percutaneous coronary intervention in 1, aortic valve re-placement in 1, Bentall procedure in 1, and coronary artery bypass grafting in 1.Results The average operation time, car-diopulmonary bypass time, aortic cross clamping time and selective cerebral perfusion time was(6.43 ±1.03) h,(167.07 ± 49.62) min,(80.74 ±29.00) min, and(27.35 ±6.03) min, respectively.Concomitant procedures included Bentall proce-dure in 6 patients, ascending aorta replacement in 17, ascending aorta-femoral artery bypass in 1, mitral valvuloplasty in 1, and CABG in 1.There were 2(8.70%) in hospital deaths.Three patients suffered temporary renal dysfunction, and 1 with re-nal failure recieved continuous renal replacement therapy .Postoperative hypoxemia were found in 2 patients, and 1 of them re-ceived reintubation.These patients recovered before discharge.The mean follow-up time was(52.52 ±9.89) months with a follow-up rate of 95.23%(20/21).One patient suffered cerebral embolism but recovered soon after treatment.The others were free from any complications.Conclusion Sun's procedure with preservation of autologous brachiocephalic vessels simplified the aortic arch surgery and obtained satisfactory outcomes for suitable patients with CTAD , but surgical indications should be strictly considered.

Procedimiento de Hartmann vs resección y anastomosis primaria en peritonitis diverticular de colon izquierdo por cirugía abierta: revisión sistemática de la literatura / Hartmann’s procedure and resection with primary anastomosis in diverticular peritonitis

Introduction: colonic diverticulosis, as diverticulitis, is a frequent disease in different stages of evolution. There is uncertainty about treatment options that are used in secondary peritonitis. The aim of this study is to determine the best treatment option for patients with peritonitis secondary to diverticulitis of the left colon in terms of postoperative morbidity (POM) and mortality, comparing Hartmann's procedure (HP) and resection with primary anastomosis (RPA). Material and Methods: systematic review. Studies in adults with peritonitis secondary to diverticulitis of the left colon treated with HP and RPA published between 1990 and 2011 were analyzed. TRIPDATABSE, IWO, MEDLINE, SciELO and LILACS databases were consulted and search strategies were applied using MeSH and free terms. Selected studies were analyzed using a score of methodological quality (MQ). The following variables were considered: mortality, POM, hospital stay, percentage of bowel transit reconstitution in patients undergoing HP and MQ of primary studies. Results: 26 primary studies were analyzed (47 series). There were no significant differences in the variable mortality (p = 0.0805), but significant difference was observed in POM (incompletely reported) (p = 0.0187). The median of MQ of the studies was 11 points for HP series and 10 for RPA series. Conclusion: the available evidence to determine the best treatment option in terms of mortality and POM in this kind of patients is insufficient. Studies with better level evidence and MQ are needed to clarify the uncertain.

Introducción: la enfermedad diverticular del colon es una entidad frecuente, como también la diverticulitis en sus diferentes estadios de evolución. Existe incertidumbre respecto de las opciones terapéuticas que se utilizan en el tratamiento de la peritonitis diverticular de colon izquierdo (PDCI). El objetivo de este estudio es determinar la mejor opción de tratamiento para pacientes con PDCI entre procedimiento de Hart-mann (PH) y resección con anastomosis primaria (RAP), en términos de mortalidad y morbilidad postoperatoria (MPO). Material y Método: revisión sistemática de la literatura. Se analizaron estudios realizados en adultos con PDCI tratados con PH y RAP, publicados entre 1990 y 2011. Se consultó en las bases de datos TRIPDATABSE, IWO, MEDLINE, SciELO y LILACS, utilizando estrategias de búsqueda con términos MeSH, palabras libres y operadores booleanos. Los estudios seleccionados fueron analizados mediante un escore de calidad metodológica (CM). Se consideraron las variables mortalidad, MPO, estadía hospitalaria, porcentaje de reconstitución de tránsito en pacientes sometidos a PH y CM de los estudios primarios. Resultados: se analizaron 26 estudios primarios (47 series de pacientes). No se encontraron diferencias significativas respecto de la variable mortalidad (p = 0,0805); pero sí en la variable MPO, reportada de forma incompleta (p = 0,0187). La mediana de la CM de los estudios primarios fue de 11 puntos para las series de PH y de 10 para las de RAP. Conclusión: la evidencia disponible no permite determinar la mejor alternativa terapéutica en términos de mortalidad y MPO en este tipo de pacientes. Se requieren estudios de mejor nivel de evidencia y CM para aclarar esta incertidumbre.

The perioperative analysis of surgery on stanford B aortic dissection / 中华胸心血管外科杂志

Objective To summarize our clinical experience and results of Stanford type B dissection,and analyzed the risk factors of reoperation.Methods From February 2009 to December 2011,81 patients (54 male and 27 female) of Stanford type B aortic dissection underwent surgical procedure in Beijing Anzhen Hospital The mean age was 19 -77 years,averaged (41.6±11.7)years.Associated with hypeftension in 48 cases,Marfan syndrome in 15 case,aortic root aneurysm in 7cases,dilation of aortic sinus and ascending aorta each in one,coarctation of the aorta in 1 case.Reoperation was done in 22cases and 4 of 22 needed the third operation.The risk factors of reoperation were analyzed with Logistic regression analysis.Results Sun (s) procedure was operated on 16 cases,concomitant procedures included Bentall in 7 cases,David in 1,replacement of the ascending aorta in 2 cases,CABG in 1 case.The thoracoabdominal aortic replacement in 31 cases,the descending thoracic aortic replacement in 9 cases,the stented elephant trunk procedure in 24 cases.Concomitant procedures included the bypass from the left subclavian artery to the left common carotid artery in 5 cases,aortic valve replacement and ascending aortic plasty in 3 cases,left subclavian artery reconstruction in 2 cases,double valve replacement in 1 cases,and the bypass from ascending aorta to descending aorta each in one,repair of internal leakage in 1 case.2 patients underwent thoracoabdominal aorta replacement died after surgery due to multiple organ failure caused by postoperative bleeding.The hospital mortality was 2.5％(2/81 cases).Complications occurred in 6 patients (6/81 cases,7.4.％ ),including diastinal bleeding requiring reoperation in 3 cases,respiratory insufficiency and hoarseness each in one,postoperative esophageal fistula needed reoperation and jejunal fistulization in I case.No paraplegia or stroke occurred postoperatively.Logistic regression analysis shows Marfan syndrome is the risk factor of reoperation.Conclusion The surgery on Stanford B aortic dissection can achieve satisfactory clinical results and Marfan syndrome is the risk factor of reoperation.The mid- and long-term results need the further follow-up.

Resultados del Tension Free Vaginal tape (TVT) en el manejo quirúrgico de las recidivas post cirugía de Burch / The results of tension free vaginal tape after Burch's technique failure

La técnica de Burch es una de las que muestra mejores resultados a largo plazo en el tratamiento de la Incontinencia Urinaria de Esfuerzo (IOE), sin embargo también presenta recidivas. El principio básico de la uretropexia de Burch es subir el cuello vesical a una posición intrabdominal retropúbica. Si este principio no funciona deben considerarse soluciones quirúrgicas basadas en otros principios fisiopatológicos para una segunda cirugía, como es el TVT. Nuestro objetivo es evaluar los resultados del TVT en pacientes recidivadas después de cirugía de Burch, para ello realizamos una revisión retrospectiva de estas pacientes que fueron operadas por segunda vez con técnica de TVT. De 129 pacientes sometidas a TVT en nuestro Servicio, 17 presentaban el antecedente de recidiva de IOE después de cirugía de Burch. El promedio de edad fue de 56,3 años. El TVT se realizó en promedio 7,75 (3 - 13) años después del Burch. El 100 por ciento de las pacientes se mantiene sin IOE después de 49,7 (2 - 84) meses de seguimiento. No tenemos pacientes con perforación vesical ni retención de orina. En 4 (23,5 por ciento) se desarrolló urgencia de Novo. Una paciente presentó erosión que cerró espontáneamente. El TVT ha demostrado en nuestras pacientes ser una excelente alternativa para tratar las recidivas del Burch, pudiendo explicarse ya que la uretra media donde debe colocarse la malla es un área quirúrgicamente virgen y porque los mecanismos para evitar la pérdida de orina son distintos en las dos técnicas.

In most published series Burch colpocystourethropexy suggest an objective success rate for primarysurgery of between 80 percent and 90 percent. The aim of our study is to evaluate TVT as treatment after Burch failure. We evaluated retrospectively 129 TVT procedures at our institution between August 2000 and August 2007. We identified 17 patients who underwent a TVT procedure for recurrent stress urinary incontinence after Burch surgery. The mean age of the patient was 56.3 years. Mean follow-up was49.7 months (range 2 to 84). TVT was performed in average 7.75 years (range 3 to13) after Burch surgery. All the patients were considered cured. Our series didn’t have immediate complications defined as bladder or bowel perforation or postoperative urinary retention. We had one patient (5.9 percent) with vaginal erosion treated successfully with supportive measures. De novo urgency occurred in 23,4 percent(4 patients). According to our data, TVT shows good outcome in the treatment of Burch failure. TVT is a safe, effective, and minimally invasive option. We believe that clinical success is achieved because the mesh is in a different area from Burch colpocystourethropexy and different continence mechanismsare involved.
