ABSTRACT
Resumo Contexto A abordagem cirúrgica para estenose carotídea sintomática está consolidada na literatura para a prevenção de eventos neurológicos, devendo seguir padrões ótimos de qualidade. Entretanto, há uma crescente preocupação relacionada à possibilidade ou não de replicar os dados dos trabalhos controlados no mundo real. Objetivos Avaliar a população com estenose carotídea sintomática submetida a cirurgia e seus desfechos de curto prazo em um contexto de mundo real em um centro de formação profissional. Métodos Tratou-se de um estudo observacional realizado por meio de coleta de dados em prontuário de janeiro de 2012 a janeiro de 2023. Foram excluídos pacientes operados por outras etiologias e com cirurgia cardíaca concomitante. Resultados Foram incluídos 70 pacientes submetidos a angioplastia ou endarterectomia carotídea. Os subgrupos populacionais submetidos a angioplastia ou endarterectomia foram semelhantes. Houve diferença estatisticamente relevante quanto à modalidade anestésica e ao tempo cirúrgico maior para o subgrupo de endarterectomia carotídea. Houve quatro casos de acidente vascular encefálico isquêmico, e três deles estavam relacionados à lesão, sendo dois menores e um maior. Dessa forma, a taxa de acidente vascular encefálico maior relacionado à lesão foi de 1,43% e de qualquer acidente vascular encefálico relacionado à lesão, de 4,29%. A taxa total de eventos adversos cardiovasculares maiores foi de 5,71%. Houve um caso de infarto agudo do miocárdio no grupo angioplastia e nenhum óbito. Não houve diferença estatística entre os grupos de endarterectomia e angioplastia quanto aos desfechos principais. Conclusões Os desfechos acidente vascular encefálico isquêmico, infarto agudo do miocárdio, óbito e eventos adversos cardiovasculares maiores neste centro são semelhantes aos encontrados em estudos clínicos randomizados, demonstrando viabilidade da manutenção deste tratamento em centros com programas de ensino.
Abstract Background Surgical treatment of symptomatic extracranial carotid stenosis is well established for preventing neurological events and should adhere to optimal quality standards. However, there is growing concern as to whether results of controlled trials are replicable in real-world settings. Objectives To assess a symptomatic carotid stenosis population that underwent surgery and its short-term outcomes in a real-world context at a professional training center. Methods Observational study using data collected from medical records from January 2012 to January 2023. Patients undergoing operations for other carotid diseases and with concomitant heart surgery were excluded. Results A total of 70 patients undergoing angioplasty or carotid endarterectomy were included. Population subsets undergoing angioplasty or endarterectomy were similar. Differences in anesthetic modality and a longer operative time in the carotid endarterectomy subgroup were statistically significant. There were 4 cases of stroke, only 3 of which (2 minor and 1 major) were related to the index lesion. Thus, the rate of major operation-related stroke was 1.43% and the rate of any lesion-related stroke was 4.29%. There was 1 case of AMI in the angioplasty group and there were no deaths in the sample. The overall rate of major adverse cardiovascular events was 5.71%. There were no statistical differences between the endarterectomy and angioplasty groups regarding the main outcomes. Conclusions The rates of outcomes of ischemic stroke, acute myocardial infarction, death, and major adverse cardiovascular events at this center are in line with the rates reported by randomized controlled trials, demonstrating the feasibility of carotid surgery in centers with teaching programs.
ABSTRACT
Objective To investigate the diagnosis and treatment strategy of the portal vein complications in children undergoing split liver transplantation. Methods The clinical data of 88 pediatric recipients who underwent split liver transplantation were retrospectively analyzed. Intraoperative anastomosis at the bifurcating site of the portal vein or donor iliac vein bypass anastomosis was performed depending on the internal diameter and development of the recipient's portal vein. A normalized portal venous blood stream monitoring was performed during the perioperative stage. After operation, heparin sodium was used to bridge warfarin for anticoagulation therapy. After portal vein stenosis or thrombosis was identified with enhanced CT or portography, managements including embolectomy, systemic anticoagulation, interventional thrombus removal, balloon dilatation and/or stenting were performed. Results Among the 88 recipients, a total of 10 children were diagnosed with portal vein complications, of which 4 cases were diagnosed with portal vein stenosis at 1 d, 2 months, 8 months, and 11 months after surgery, and 6 cases were diagnosed with portal vein thrombosis at intraoperative, 2 d, 3 d (n=2), 6 d, and 11 months after surgery, respectively. One patient with portal vein stenosis and one patient with portal vein thrombosis died perioperatively. The fatality related to portal vein complications was 2% (2/88). Of the remaining 8 patients, 1 underwent systemic anticoagulation, 2 underwent portal venous embolectomy, 1 underwent interventional balloon dilatation, and 4 underwent interventional balloon dilatation plus stenting. No portal venous related symptoms were detected during postoperative long term follow up, and the retested portal venous blood stream parameters were normal. Conclusions The normalized intra- and post-operative portal venous blood stream monitoring is a useful tool for the early detection of portal vein complications, the early utilization of useful managements such as intraoperative portal venous embolectomy, interventional balloon dilatation and stenting may effectively treat the portal vein complications, thus minimizing the portal vein complication related graft loss and recipient death.
ABSTRACT
Stroke is the leading cause of death among urban and rural residents in China. About 25% to 30% of ischemia stroke is related to atherosclerotic carotid stenosis. The main treatments for carotid stenosis include carotid endarterectomy, carotid artery stenting and best medical therapy. In recent years, clinical trial evidence on the treatment of carotid artery stenosis continues to emerge, in which a series of new arguments and consensus have emerged. In addition, with the innovation of surgical techniques and the reform of intracavitary instruments, new surgical techniques and surgical equipment have been extended. This article summarizes the latest evidence-based and technical progress in the treatment of carotid artery stenosis in recent years, in order to provide theoretical guidance for the clinical practice of carotid artery stenosis.
ABSTRACT
Objective:To investigate the risk factors related to the contrast-induced nephropathy(CIN)occurring after carotid artery stenting(CAS)in patients with carotid artery stenosis.Methods:The clinical data of 137 patients with carotid artery stenosis, who were treated with CAS at Xuanwu Hospital, Capital Medical University during the period from January to Decmber 2021 were retrospectively analyzed. Record demographic characteristics (age, gender, height, weight), history of underlying diseases (hypertension, diabetes, kidney disease, etc.), history of medications, etc. Observe the clinical parameters such as creatinine, blood urea nitrogen, albumin, hemoglobin, hematocrit, degree of stenosis and estimated glomerular filtration rate (eGFR). Measurement data conforming to the normal distribution were expressed as the mean±standard deviation( ± s), and the t-test was used for comparison between groups; the measurement data that does not conform to the normal distribution were expressed as the median (interquartile range) [ M( Q1, Q3)], and the Rank-sum test was used for comparison between groups; the Chi-square test or Fisher exact test was used for comparison of count data between groups. Relevant variables were subjected to univariate analysis, and statistically significant indicators were selected according to the results of univariate analysis to be included in the multivariate Logistic regression analysis. Results:After CAS, a total of 29 patients (21.2%) among the 137 patients developed CIN. Univariate analysis indicated that bilateral carotid artery stenosis, uncontrolled hypertension before surgery, history of angiotensin converting enzyme inhibitor drugs, diabetes mellitus, history of insulin drugs, eGFR<45 mL/(min·1.73 m 2), body weight were the influencing factors associated with the occurrence of CIN after CAS in patients with carotid artery stenting; multivariate regression analysis revealed that the presence of bilateral carotid artery stenosis( OR=4.724, 95% CI: 1.455-15.338, P=0.010), diabetes mellitus( OR=3.451, 95% CI: 1.345-8.858, P=0.010) and eGFR <45 mL/(min·1.73 m 2)( OR=4.582, 95% CI: 1.001-20.971, P=0.050) were the independent risk factors related to the CIN after CAS. Conclusion:Patients with the presence of bilateral carotid artery stenosis, diabetes mellitus or eGFR <45 mL/(min·1.73 m 2) are more likely to develop CIN after CAS.
ABSTRACT
Objective To analyze the risk factors and build a clinical prediction model for hemodynamic depression (HD) after carotid artery stenting (CAS). Methods A total of 116 patients who received CAS in the Department of Vascular Surgery,Drum Tower Clinical College of Nanjing Medical University and the Department of Vascular Surgery,the Affiliated Suqian First People's Hospital of Nanjing Medical University from January 1,2016 to January 1,2022 were included in this study.The patients were assigned into a HD group and a non-HD group.The clinical baseline data and vascular disease characteristics of each group were collected,and multivariate Logistic regression was employed to identify the independent predictors of HD after CAS and build a clinical prediction model.The receiver operating characteristic (ROC) curve was drawn,and the area under the ROC curve (AUC) was calculated to evaluate the predictive performance of the model. Results The HD group had lower proportions of diabetes (P=0.014) and smoking (P=0.037) and higher proportions of hypertension (P=0.031),bilateral CAS (P=0.018),calcified plaque (P=0.001),eccentric plaque (P=0.003),and the distance<1 cm from the minimum lumen level to the carotid bifurcation (P=0.009) than the non-HD group.The age,sex,coronary heart disease,symptomatic carotid artery stenosis,degree of stenosis,and length of lesions had no statistically significant differences between the HD group and the non-HD group (all P>0.05).Based on the above predictive factors,a clinical prediction model was established,which showed the AUC of 0.807 and the 95% CI of 0.730-0.885 (P<0.001).The model demonstrated the sensitivity of 62.7% and the specificity of 87.7% when the best cut-off value of the model score reached 12.5 points. Conclusions Diabetes,smoking,calcified plaque,eccentric plaque,and the distance<1 cm from the minimum lumen level to the carotid bifurcation are independent predictors of HD after CAS.The clinical prediction model built based on the above factors has good performance in predicting the occurrence of HD after CAS.

【Objective】 To investigate the predictive value of regional cerebral oxygen saturation (rScO2) monitoring during total aortic arch replacement and stent trunk surgery for perioperative neurocognitive disorders (PND) and changes in plasma S100β protein and neuron-specific enolase (NSE) concentrations and their relationship with PND. 【Methods】 Sixty-five Stanford type A aortic dissection patients who planned to undergo total aortic arch replacement and trunk stenting were selected. Their rScO2 values were monitored throughout the operation and recorded after induction (T1), the beginning of CPB (T2), during deep hypothermic circulatory arrest (T3), rewarming to 36℃(T4), CPB stop for 1 hour (T5), and post-operation (T6). After induction (Ta), rewarming to 36℃ (Tb),1 h (Tc), 6 h (Td) and 24 h (Te) after cessation of cardiopulmonary bypass, central venous blood was collected from patients, and the concentrations of S100β protein and NSE in plasma were detected by ELISA. The patients were divided into PND group and non-PND group by the evaluation of MMSE scale at time of before operation, on the day of extubation, and 7 days after operation. 【Results】 The incidence of PND was 44.6%. The rScO2 value at T2 was significantly lower than that at T1 (P<0.05). The rScO2 value of PND group at T3 and T6 was significantly lower than that at T1 and non-PND group (P<0.05). The mean value of rScO2 and the minimum value of rScO2 in PND group were significantly lower than those in non-PND group, while rScO2 %max in PND group was significantly higher than that in non-PND group (P<0.05). The intraoperative critical value of rScO2 %max was >9.89%, the area under curve (AUC) was 0.658 (95% CI: 0.525-0.791, P<0.05), and sensitivity and specificity were 48.3% and 75.0%, respectively. The concentrations of S100β protein and NSE protein in PND group were significantly higher than those in non-PND group at Tc and Td (P<0.01). Compared with Ta, the concentration of S100β protein in PND group was significantly increased at Tc and Td (P<0.001), and the concentration of NSE protein was significantly increased at Tb-Te (P<0.01). CPB time was an independent risk factor for PND. 【Conclusion】 The occurrence of PND after total arch replacement and stenting may be related to the decrease of rScO2 and the increase of S100β protein and NSE protein. Intraoperative rScO2 %max >9.89% can be a potential predictor of PND.

ABSTRACT
Objective:To compare the perioperative outcomes and safety of percutaneous nephrostomy (PCN) and retrograde ureteral stenting (RUS) in the treatment of acute obstructive upper urinary tract infection.Methods:A comprehensive search was performed on the MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials to identify relevant literatures. The retrieval period was from the establishment of the database to August 2022. Inclusion criteria: ①Randomized controlled trial (RCT) of PCN and RUS in the treatment of acute obstructive upper urinary tract infection; ②Studies provided accurate data for analysis, including the total number of subjects and the results of each index; ③The full text of the study was available, and different literatures published in the same cohort were included in the newly published data. ④The observation indexes included the time for the recovery of body temperature, creatinine, leukocyte, operation, radiation exposure, postoperative fever, postoperative pain, and the incidence of postoperative fistulotomy or stent displacement. Exclusion criteria: ①non-RCT study; ②unable to obtain the full text. Two researchers independently screened the literature and evaluated the literature quality, and all the statistical data were analyzed by RevMan5.3 software.Results:Seven trials enrolled 727 patients were included in the meta-analysis, 412 in the PCN group and 315 in the RUS group included. Meta-analysis revealed that the advantages of PCN were lower incidence of postoperative hematuria ( OR=0.54, 95% CI 0.30-0.99, P=0.040) and lower incidence of insertion failure ( OR=0.42, 95% CI 0.21-0.81, P=0.010), but the fluoroscopy time of RUS group was shorter than that of PCN group ( MD=0.31, 95% CI 0.14-0.48, P<0.01). Moreover, there was no significant difference in time to normalization of temperature, time to normalization of creatinine, time to normalization of WBC, operative time, postoperative fever, postoperative pain, postoperative nephrostomy tube or stent slippage rate between the two surgical methods( P>0.05). Conclusions:The radiation exposure time of PCN was longer than that of RUS, but the incidence of postoperative hematuria and catheterization failure was lower than that of RUS.
ABSTRACT
Background: Hydronephrosis is a major urological health problem in children. Pelviretic junction (PUJ) obstruction is common among the congenital causes of hydronephrosis. A-H pyeploplasty is the most popular and common technique. There are different modalities of using trans-anastomotic stent in A-H pyeloplasty. Some surgeons use external drainage like nephrostomy tube, pyelostomy tube or trans-anastomotic stent and others use internal drainage D-J stent. In this study, D-J stent and BMI feeding tube were used for trans anastomotic drainage. We analyzed the data to find out which method of stenting in A-H pyeloplasty is more effective and safer and also to reduce the morbidity by reducing stent related complications.Material & Methods:A prospective interventional study was conducted in the faculty of Paediatric Surgery inBangladesh Shishu Hospital and Institute during the period from January 2016 to December 2019. A total of 60 patients under 12 years of age were included in this study were diagnosed as uni-lateral hydronephrosis for PUJ obstruction. Patients were divided into two groups by random lottery method and all patients underwent A-H pyeloplasty under general anaesthesia (G-A). In group-A, A-H pyeloplasty were done with using Double (D-J) stent and in group-B, 5Fr or 6Fr BMI tube were used as trans-anastomotic drainage. Patients were followed up after 2 weeks of operation, at 3 months and them at 6 months. The variables of the post-operative follow up study were patency of anastomosis, urinary tract infection, (UTI), urinary leakage and post-operative hospital stay and statistical analysis were done.Results:In group-A (30 cases), Anderson-Hynes pyeloplasty were done using D-J stent and in group-B (30 cases) with using trans-anastomotic BMI tube. In group-A most (73.33%) patients were below 5 years and in group-B 48 patients (80%) were below 5 years. In group-A mean age was 3.57+ 3.11 years and in group-B mean age was 3.31+3.21 years. There is no statistically significant difference in age distribution. In group-A left kidney were involved 66.7% cases and in group B in 80% cases left kidney were involved. In the early post-operative period, no urinary obstruction in group-A, however in 20% cases developed urinary obstruction in group-B but that was not statistically significant. In group-B continuous urinary leakage through drain tube was for 0-15 days but in group-B leakage was only or 0-1 day. It was statistically significant (p=0.037). In group-A, range of time of removal of drain tube was 4 days but in group-B range was 8-27 days. It was statistically significant (p=0.0001). Hospital stay in group-A was 4-8 days and in group B 9-29 days. It was also statistically significant (p=0.0001).Conclusion: In A-H pyeloplasty, morbidity of the patients can be reduced by using D-J stent which is more effective and safer. We found definite statistically significant difference in terms of urinary leakage, post-operative UTI, and hospital stay.
ABSTRACT
Obstruction of the superior vena cava (SVC) is a rare complication after cardiac surgery in infants and children. We present the case of a 2-year-old male child who underwent surgery to repair a mixed total anomalous pulmonary venous connection. After 18 months of surgery, the child developed SVC syndrome. Transcatheter stenting was performed to relieve the SVC obstruction detected with transthoracic echocardiography. The patient was discharged after 5 days of hospitalization. The patient was doing well at follow-up appointments, with good laminar flow through the stent. In conclusion, transcatheter management of post-surgical complications of SVC obstruction was successful in this patient.
ABSTRACT
Abstract Introduction: The current standard treatment for bifurcation lesions is the provisional stent technique, by implanting only one stent in the main branch; however, in certain cases, the use of more complex techniques that require double stenting should be considered. Objective: To perform a clinical and angiographic assessment of patients with true bifurcation lesions treated with the two-stent culotte technique. Materials and methods: A prospective study was done, which included patients diagnosed with significant obstructive coronary artery disease in bifurcation areas, who were candidates for angioplasty with culotte technique. The study included 44 patients with proved diagnosis of coronary bifurcation lesions; 66% of the treated bifurcation lesions compromised the anterior descending artery and the diagonal branch and 27%, the circumflex artery with the marginal branch. It was found that 68% of the cases had Medina 1,1,1 lesions and 23% had Medina 0,1,1 lesions. Six months later, it was found that 12.5% of the patients followed up by angiography had in-stent restenosis (ISR) > 50% that involved at least one of the bifurcation areas. In 9% of these patients, the ISR was at the origin of the side branch only, and in 3%, the ISR was confined to the distal segment of the main branch stent. Conclusion: The use of the culotte technique with two new-generation stents to treat complex coronary bifurcation lesions is an effective option and does not increase the risk of complications during the procedure nor the risk of the appearance of ISR.
Resumen Introducción: El tratamiento estándar actual para las lesiones en bifurcaciones es la técnica de stent provisional, implantando solo un stent en la rama principal, sin embargo, en ciertos casos, se debería considerar el uso de técnicas más complejas que requieren de doble stent. Objetivo: Realizar una evaluación clínica y angiográfica de pacientes con verdaderas lesiones en bifurcaciones tratados con la técnica culotte de doble stent. Material y métodos: Se realizó un estudio prospectivo que incluyó pacientes diagnosticados con enfermedad obstructiva significativa de arterias coronarias en bifurcaciones, quienes eran candidatos a angioplastia con la técnica culotte. El estudio incluyó 44 pacientes con un diagnóstico comprobado de lesiones coronarias en bifurcaciones; el 66% de las lesiones en bifurcaciones tratadas comprometían la arteria descendente anterior y la rama diagonal, y el 27% la arteria circunfleja con la rama marginal. Se encontró que el 68% de los casos tenían lesiones Medina 1,1,1 y el 23% tenían lesiones Medina 0,1,1. A los seis meses, se encontró que el 12,5% de los pacientes en seguimiento con angiografía presentaban reestenosis intrastent (RIS) mayor al 50%, que comprometía al menos una de las áreas de bifurcación. En el 9% de estos pacientes, la RIS se ubicaba únicamente en el origen de la rama lateral, y en el 3%, la RIS se restringió al segmento distal del stent de la rama principal. Conclusiones: El uso de la técnica culotte empleando dos stents de nueva generación es una opción efectiva para tratar las lesiones complejas en bifurcaciones coronarias, y no aumenta el riesgo de complicaciones durante el procedimiento ni el riesgo de la aparición de reestenosis intrastent.
ABSTRACT
Extra corporeal membrane oxygenation (ECMO) for refractory out?of?hospital cardiac arrest (OHCA) has been shown to improve outcome in many Western countries. There are no reports of ECMO being used to support OHCA in India till date. We report a case of a young man who developed cardiac arrest (CA) while driving and was given bystander cardiac massage. He was brought to tertiary care center where an ECMO was utilized for refractory CA. The patient subsequently underwent emergency coronary artery stenting and was weaned off ECMO and ventilation. We discuss the case and highlight the role of bystander cardiopulmonary resuscitation.
ABSTRACT
Objective:To investigate the correlation between intraplaque hemorrhage (IPH) and new-onset embolic cerebral infarction after basilar artery angioplasty or stenting.Methods:Consecutive patients with severe basilar atherosclerotic stenosis underwent basilar artery angioplasty or stenting in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2015 to February 2022 were retrospectively enrolled. High resolution magnetic resonance vessel wall imaging (HRMR-VWI) and diffusion-weighted imaging (DWI) were performed within one week before procedure, and brain DWI or CT examination was performed within 72 h after procedure to determine the patients with new-onset embolic cerebral infarction.Results:A total of 32 patients were enrolled in the analyze. IPH existed in 10 patients with basilar artery culprit plaque, and 5 had new-onset embolic cerebral infarction after procedure. The incidence of embolic cerebral infarction in the IPH group was significantly higher than that in the non-IPH group (50% vs. 0%; P=0.001). The proportion of patients with IPH in the embolic cerebral infarction group was significantly higher than that in the non-embolic cerebral infarction group (100% vs. 18.5%; P=0.001). Conclusion:IPH may be associated with new-onset embolic cerebral infarction after basilar artery angioplasty or stenting.
ABSTRACT
Abstract Introduction: Hemodynamic Depression (HD) characterized by hypotension and bradycardia is a complication of carotid surgery due to direct autonomic stimulation in the carotid sinus. The authors believe the incidence of HD is high and possibly related to major cardiac complications. Methods: Analysis of patient records during admissions for carotid surgery between January 2014 and December 2018 in two hospitals. HD was defined as bradycardia or hypotension in the first 24 postoperative hours. Bradycardia was defined as heart rate < 50bpm; hypotension as systolic blood pressure < 90 mmHg, continuous use of vasopressors, or a drop in SBP > 20% compared to preoperative values. Myocardial infarction, stroke, and cardiovascular death were defined as adverse events. Results: Overall, 237 carotid surgeries (178 endarterectomies, 59 angioplasties) were studied, and the global incidence of HD was 54.4% (hypotension in 50.2%, bradycardia in 11.0%, and hypotension and bradycardia in 6.8%). The independent predictors of HD were asymptomatic carotid stenosis (OR = 1.824; 95% CI 1.014 −3.280; p = 0.045), endovascular surgery (OR = 3.319; 95% CI 1.675−6.576; p = 0.001) and intraoperative hypotension or bradycardia (OR = 2.144; 95% CI 1.222−3.762; p = 0.008). Hypotension requiring continuous vasopressor infusion was the only factor independently associated with adverse cardiovascular events (OR = 5.504; 95% CI 1.729-17.529; p = 0.004). Discussion/conclusion: Incidence of Hemodynamic Depression after carotid surgery is high and independently associated with surgical technique, symptomatic repercussion of the carotid stenosis, and intraoperative hypotension or bradycardia. Hypotension requiring the continuous infusion of vasopressors was independently associated with the occurrence of MACE.
ABSTRACT
@#Objective To analyze the short-term and long-term efficacy of staged coronary artery bypass grafting (CABG) and carotid artery stenting (CAS) compared with CABG alone in patients with coronary heart disease with preoperative history of stroke and carotid stenosis. Methods We reviewed the clinical data of 55 patients (48 males, 7 females, aged 67.62±7.06 years) with coronary heart disease and carotid stenosis who had a history of stroke and underwent CABG+CAS or CABG alone in Zhongshan Hospital from 2008 to 2017. There were 13 patients in the staged CABG+CAS group and 42 patients in the CABG alone group. The differences in the incidence of perioperative adverse events and long-term survival between the two groups were studied, and univariate and multivariate analyses were carried out to determine the independent risk factors of long-term adverse events. Results Perioperative adverse events occurred in 1 (7.69%) patient of the staged CABG+CAS group, and 4 (9.52%) patients of the CABG alone group (P=0.84). During the follow-up period (67.84±37.99 months), the long-term survival rate of patients in the staged CABG+CAS group was significantly higher than that in the CABG alone group (P=0.02). The risk of long-term adverse events in the staged CABG+CAS group was 0.22 times higher than that in the CABG alone group (95%CI 0.05-0.92, P=0.04). Conclusion Staged CABG+CAS can significantly improve the long-term survival prognosis without increasing the perioperative risk. It is a safe and effective treatment, but prospective randomized studies are still needed to further confirm this finding.
ABSTRACT
Objective:The perioperative and early follow-up data of the simultaneous hybrid CAS+ OPCABG and sequential CAS+ OPCABG were compared to evaluate the safety and efficacy of the simultaneous CAS+ OPCABG.Methods:A total of 26 patients with coronary heart disease complicated with carotid artery stenosis received CAS plus OPCABG hybrid surgery in our hospital from January 2020 to July 2021, among which 12 patients received simultaneous CAS+ OPCABG and 14 patients received staged sequential CAS+ OPCABG.The perioperative and postoperative follow-up data of 3 months were compared and analyzed.Results:There were no significant differences in the operation time, drainage on the first day after surgery, ventilator assisted time and ICU time between the two groups.The amount of intraoperative blood loss in the simultaneous group was more than that in the staged group, but no secondary thoracotomy occurred in both groups. The number of days in hospital after operation was significantly less in the simultaneous group. There was 1 case of perioperative cerebral infarction and 1 case of myocardial infarction in the staged group, but there was no statistical difference between the two groups. There was no new cerebral infarction in the two groups, carotid artery ultrasound stent was unobstructed, and there was no statistical difference in cardiac function grading and left ventricular ejection fraction 3 months after operation.Conclusion:Simultaneous CAS+ OPCABG surgery is safe and feasible, it is recommended as the first choice especially for patients with severe myocardial ischemiaor severe left main artery disease caused.How to reduce the risk of bleeding and alleviat carotid sinus reflex are major issues that need to be concerned.
ABSTRACT
Objective:To evaluate the efficacy of different carotid artery revascularization strategy in sychronous carotid and coronary artery revascularization.Methods:The clinical data of 53 patients receiving simultaneous carotid and coronary artery revascularization in China-Japan Friendship Hospital from Jan 2014 to Dec 2019 was retrospectively analyzed. The clinical characteristics, imaging examination, treatment and prognosis were collected and reviewed. Patients were divided into CEA group (42 cases) and CAS group (11 cases) according to the carotid artery revascularization method.Results:The mean operative time and blood loss of CEA group were (288.81±43.28) min and (419.05±127.33) ml, respectively. The mean operative time and blood loss of CAS group were (251.82±23.16) min and (318.18±98.16) ml, respectively. The difference of operative time and blood loss between the 2 groups were not significant (all P>0.05). Four minor strokes, 4 transient ischemic attacks (TIA), 2 pulmonary infections and 4 recurrent laryngeal nerve injury were observed in CEA group. Two TIA and 1 re-thoracotomy for hemostasis occurred in CAS group. Conclusions:Both carotid endarterectomy and carotid stenting can achieve good clinical result in synchronous carotid and coronary artery revascularization procedure. The selection of proper carotid artery revascularization method should base on the lesion characteristic and surgeon's experience.
ABSTRACT
Objective:To compare carotid endarterectomy (CEA) and carotid artery stenting (CAS) in perioperative, medium and long term prognosis of patients with carotid artery stenosis.Methods:A retrospective analysis was performed on 1 329 cases of carotid artery stenosis treated at Department of Vascular Surgery, Beijing Anzhen Hospital from Jan 2011 to Aug 2020, as all cases being divided into CAS group and CEA group.Results:There were significant differences in age ( t=0.098, P=0.023) and drinking habits ( χ2=8.055, P=0.005) between the two groups. There were more unstable plaques in CEA group ( χ2=4.392, P=0.038), and more bilateral lesions in CAS group ( χ2=9.673, P=0.038). In perioperative period, there were more mannitol use in CEA group ( χ2=78.614, P<0.001), more incision/puncture site complications ( χ2=5.158, P=0.035), lung infection ( χ2=6.355, P=0.013), cerebral hyperperfusion syndrome (CHS) ( χ2=5.158, P=0.035) and extracranial nerve injury ( χ2=23.760, P<0.001) in CEA group than in CAS group, and more acute renal failure in CAS group ( χ2=10.393, P=0.001). There was no significant difference in survival rate and ischemic stroke, myocardial infarction, cerebral hemorrhage and renal insufficiency between the two groups (all P>0.05). The mean survival time of CAS group was 53.195 months (95% CI: 52.040-54.350), and 54.492 months (95% CI: 53.790-55.195) in CEA group ( P=0.051). Conclusions:Patients in CEA group had more unstable plaque and a lower perioperative stroke rate. CEA group had higher risk of CHS,while CAS was with lower postoperative lung infection rate and less wound local complications. There was no significant difference in long-term survival between the two groups.
ABSTRACT
Objective:To investigate the effect of mind mapping on the discharge readiness of patients undergoing first coronary stent implantation, so as to provide basis for seeking effective discharge guidance in clinical practice.Methods:One hundred patients who were hospitalized in the Department of Cardiology, the Second Affiliated Hospital of Dalian Medical University from December 2019 to August 2020 and who underwent coronary stent implantation for the first time were selected as the study objects. They were divided into the control group and the experimental group with 50 cases in each group by the random number table method. The control group was given routine discharge guidance, and the experimental group was given discharge guidance using mind mapping. Readiness for Hospital Discharge Scale and Quality of Discharge Teaching Scale were used to compare the differences of discharge readiness and discharge guidance quality between the two groups after intervention.Results:The personal status, adaptability, predictive support and the total score of discharge readiness in the experimental group were (25.18 ± 3.79), (45.24 ± 3.63), (36.62 ± 3.63), (107.04 ± 8.92) points, which were all higher than those in the control group (23.34 ± 3.04), (41.68 ± 3.62), (35.14 ± 2.14), (100.16 ± 7.36) points, with statistically significant differences ( t values were -4.91--2.48, all P<0.05). The actual acquired content, guiding skills and results, total scores of discharge guidance quality of patients in the experimental group were (56.66 ± 6.06), (94.46 ± 4.33), (151.12 ± 8.26) points, which were all higher than those in the control group (45.38 ± 9.19), (89.44 ± 10.87), (134.82 ± 14.31) points, with statistically significant differences ( t values were -7.25, -3.03, -6.97, all P<0.05). Conclusions:Mind mapping can effectively improve the discharge preparation degree and discharge guidance quality of patients undergoing coronary stent implantation for the first time, and it is a simple and practical discharge guidance tool.
ABSTRACT
SUMMARY OBJECTIVE: The objective of this study was to compare the interventions of percutaneous transluminal drug-coated balloon angioplasty (DCB PTA) and standard PTA in the treatment of patients with the below-the-knee peripheral artery disease (BTK PAD). METHODS: Overall, 196 patients (113 males and 83 females; mean age: 63.56±11.94 years; 45-83 years) were treated with PTA for BTK PAD between June 2014 and March 2019. RESULT: Standard PTA (group 1; 96 patients) and DCB PTA (group 2; 100 patients) results were analyzed and compared retrospectively. No statistically significant difference was found between the mean ages of group 1 and 2 patients (p=0.371, p>0.05). Demographic and clinical data were compared and no any statistically significant differences was found between the two groups. Comparing in terms of the iliac lesion, there was no statistically significant difference between the two groups. However, a statistically significant difference was found between the two groups in terms of frequency of popliteal lesions (p=0.001; p<0.05). There was not a statistically significant difference between the two groups in terms of other lesions. In addition, limb salvage rates were 82.0% (18 amputations) and 65.6% (33 amputations) in the drug-release balloon group and the naked balloon group, at the end of 1 year, respectively. No distal embolism, limb-threatening ischemia, and mortality were observed in any patients. CONCLUSIONS: Based on this study, patients in the DCB group had significantly higher rates of primary patency as compared with the other patients.
