ObjectiveTo evaluate safety and effectiveness of stent placement and emergency surgery in treatment of proximal colon cancer obstruction.MethodsThe PubMed, Embase, Cochrane Library, ClinicalTrials, CNKI, CBM, Wanfang Data, etc. were searched comprehensively. The literatures of Chinese and English randomized controlled trial and retrospective comparative study of stent placement and emergency surgery for the proximal colon cancer obstruction were retrieved. The RevMan 5.3 and Stata 12.0 softwares were used. The meta-analysis was made on the safety and effectiveness of these two treatments.ResultsA total of 9 literatures involving 636 patients were included, all of them were the retrospective studies, 4 of them only reported the clinical success rate and technical success rate. The technical success rate of stent placement was 0.94 [95% CI (0.91, 0.96)]. The clinical success rate was 0.90 [95% CI (0.87, 0.93)]. Compared with the emergency surgery group, the total complication rate and the temporary stoma rate were lower [OR=0.32, 95% CI (0.11, 0.94), P=0.04; OR=0.18, 95% CI (0.05, 0.65), P=0.009] and the hospital stay was shorter [MD=–2.97, 95% CI (–4.52, –1.41), P=0.000 2] in the stent placement group. The perioperative mortality rate, laparoscopic surgery rate, 5-year disease-free survival rate, and 5-year overall survival rate had no significant differences between these two groups (P>0.05).ConclusionCompared with emergency surgery, endoscopic stent placement for treatment of proximal colon cancer obstruction has a lower incidence of complications, temporary colostomy rate, shorter hospital stay, and it has no significant differences in mortality, laparoscopic surgery rate, and survival rate.
ObjectiveTo summarize the feasibility and effectiveness of endovascular treatment for vertebral artery stenosis ectopic originating from the aortic arch. MethodThe clinical data of 5 patients with vertebral artery stenosis ectopic originating from aortic arch admitted to Xuanwu Hospital of Capital Medical University from January 2020 to May 2023 were retrospectively analyzed. ResultsAll 5 patients underwent magnetic resonance angiography and CT angiography before treatment. The vertebral arteries of all patients originated from the aortic arch and were severe stenosis, with a median diameter of 1.3 mm (range, 1.1–1.5 mm) by CT angiography. All 5 patients were successfully treated with endovascular intervention. The operation time was 37–45 min, with a median of 39 min. There were no complications of vertebral artery rupture, embolism or occlusion, cerebral infarction, plaque abscission, hematoma at puncture site, pseudoaneurysm, postoperative hemorrhage, or perioperative pulmonary infection. The patients were followed-up for 13–30 months, with a median follow-up time of 20 months. The blood vessels of 5 patients remained unobstructed and no clinically significant vascular restenosis occurred. ConclusionsBased on the experiences of 5 cases of vertebral artery stenosis ectopic originating from the aortic arch, it is safe and effective to choose endovascular treatment for severe symptomatic vertebral artery stenosis. Especially, it is necessary to evaluate the stenosis degree of vertebral artery using CT angiography before treatment.
Objective To systematically review the effectiveness and safety of coronary artery bypass grafting (CABG) versus percutaneous coronary stent implantation (PCI) in the treatment of patients with unprotected left main coronary artery disease (ULMCA). Methods Databases including The Cochrane Library (Issue 2, 2012), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP were electronically searched from inception to September 2012 for randomized controlled trials on the effectiveness and safety of coronary artery bypass grafting (CABG) versus percutaneous coronary stent implantation (PCI) for ULMCA; References of the included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then, meta-analysis was performed using RevMan 5.0. Results Four studies were included involving 1 611 cases, of which, 802 cases are in the CABG group, while 809 cases were in the PCI group. The results of meta-analysis showed that: comparing with PCI, CABG significantly reduced the postoperative repeat revascularization rate (OR=0.45, 95%CI 0.31 to 0.66, Plt;0.000 1), but there was no significant difference between the two groups in reducing the myocardial infarction incidence (OR=1.28, 95%CI 0.47 to 3.48, P=0.63), mortality rate (OR=1.36, 95%CI 0.80 to 2.34, P=0.26), and the incidence of major adverse cardio-cerebral vascular events (OR=0.92, 95%CI 0.66 to 1.28, P=0.61). Conclusion This study indicates that CABG is superior to PCI in reducing postoperative rate of target vessel revascularization. But CABG and PCI are alike in reducing myocardial infarction incidence, mortality rate, and the incidence of major adverse cardio-cerebral vascular events. Due to the limited quantity and quality of the included studies, the above conclusion needs to be verified by more high quality RCTs.
ObjectiveTo systematically review the long-term efficacy of coronary artery bypass grafting (CABG) versus drug-eluting stent implantation (DES-PCI) for patients with multivessel coronary artery disease. MethodsWe searched The Cochrane Library (Issue 2, 2015), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP to collect randomized controlled trials (RCTs) about CABG versus DES-PCI for patients with coronary multivessel disease from the inception to October 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.2 software. ResultsA total of seven RCTs, involving 5 723 patients were included. The results of meta-analysis showed that: compared with the DES-PCI group, the CABG group had lower 1-year incidence of target vessel revascularization (OR=0.39, 95%CI 0.31 to 0.48, P<0.000 01), 5-year mortality (OR=0.78, 95%CI 0.65 to 0.94, P=0.008), and 5-year incidence of myocardial infarction (OR=0.46, 95%CI 0.37 to 0.58, P<0.000 01). However, 1-year, 2-year and 5-year incidences of stroke in the CABG group were significantly higher than that in the DES-PCI group (all P values <0.05). ConclusionThe available evidence suggests that CABG is superior to DES-PCI for patients with multivessel coronary artery disease in long-term effects, but CABG could increase the incidence of stroke. Due to the quantity and quality of the included studies, the above conclusions still need to be verified by more high-quality RCTs.
Currently, transcatheter intervention has emerged as a first-line treatment for coarctation of the aortic. Due to the radiation exposure associated with catheter interventional therapy, there are numerous restrictions, which harms both patients and medical personnel and is dependent on sizable radiation apparatus. Here, we report for the first time a case of echo-guiding percutaneous aortic stent implantation for a 27 years female patient of reproductive age. After discharge, the patient's aortic coarctation pressure decreased to 18 mm Hg, and the surgical results were satisfactory.
ObjectiveTo investigate the effects of a new anti-anxiety-depression drug tandospirone on heart rate variability (HRV) and QT-dispersion in patients with anxiety and depression after intracoronary stent implantation. MethodsEighty-six anxious and depressive patients after intracoronary stent implantation during May 2011 and May 2013 were treated by tandospirone for 6 weeks. We evaluated the changes of HRV and QT dispersion before and after anti-anxiety-depression treatment. ResultsAfter six weeks of treatment, the HRV was increased obviously (P<0.05) and the QT dispersion was decreased significantly (P<0.01). ConclusionThe new anti-anxiety-depression drug tandospirone is effective on cardiac autonomic nervous system in patients with anxiety and depression after intracoronary stent implantation. And the drug is secure with a low rate of adverse reactions.
Objective To explore the influence of applying the fast-track surgery (FTS) to optimize the process in the perioperative period of cardiac intervention on the rehabilitation of patients with radial artery stenting surgery. Methods A total of 190 patients with radial artery stenting surgery in the Department of Cardiology, West China Hospital from June 2017 to May 2018 were enrolled. They were randomized into a control group (n=95) and a FTS group (n=95) by random umber table. There were 60 males and 35 females aged 35-88 (65.2±9.6) years in the control group as well as 62 males and 33 females aged 34-86 (61.5±11.3) years in the FTS group. Patients in the control group received routine perioperative care, but patients in the FTS group received individual precision interventions by applying the FTS concept to optimize the process of perioperative care, including individual care management before being admitted into hospital, during hospital, and after discharge from hospital. Duration of hospital stay, satisfaction scores, number of comorbidities after surgery, disease self-management ability, and readmission rates were compared between the two groups. Results Compared to the control group, the FTS group had significantly shorter duration of hospital stay, less comorbidities, higher satisfaction scores and disease self-management ability, and lower readmission rate to hospital (P<0.05). Conclusion Applying FTS into the perioperative period of cardiac interventions to optimize its process can help patients recover from radial artery stenting surgery, increase patients’ self-management abilities, shorten duration of hospital stay and decrease comorbidities and cardiac adverse events.
ObjectiveTo investigate the factors related to recurrent coronary events in patients after coronary artery stent implantation. MethodsWe retrospectively studied the patients performing coronary angiography (CAG) who were admitted to the Department of Cardiology of the Second Affiliated Hospital of Guangzhou Medical University between January 2012 and June 2013. All of the enrolled patients had received CAG in our hospital, with complete coronary angiogram and clinical data. The patients were divided into two groups according to the coronary angiogram and clinical data: coronary event group and non-coronary event group. SPSS 16.0 software was employed for statistical analysis, and multivariate analysis was performed using binary logistic regression model to analyze the risk factors. ResultsA total of 115 patients were included, of which 50 patients had recurrent coronary events. Both the serum total bilirubin and unconjugated bilirubin in patients with coronary events were significantly lower compared with the patients without coronary events at baseline and at the time of CAG reexamination (P < 0.05 or P < 0.01). The serum total bilirubin at baseline and the serum total bilirubin and unconjugated bilirubin at the time of CAG reexamination were significantly lower in patients with revasculization due to the progression of coronary artery lesions compared with the patients without coronary events (P < 0.05 or P < 0.01). The serum unconjugated bilirubin in patients with in-stent restenosis were significantly lower compared with the patients without coronary events at baseline and at the time of CAG reexamination (P < 0.05). The results of logistic regression analysis showed that multi-vessel coronary artery disease (two-vessel coronary artery disease: OR=10.094, 95%CI 2.498 to 40.798, P=0.001; three-vessel coronary artery disease: OR=16.047, 95%CI 4.121 to 62.481, P=0.000) and low serum unconjugated bilirubin (OR=0.873, 95%CI 0.773 to 0.987, P=0.03) were independent risk factors of recurrent coronary events. ConclusionMulti-vessel coronary artery disease and low serum unconjugated bilirubin are independent risk factors of recurrent coronary events in patients after coronary artery stent implantation.
ObjectiveThis study was aimed to evaluate the clinical efficacy of mechanical thrombectomy using the AngioJet System for the treatment of lower extremity acute arterial embolism and thrombosis.MethodsThe clinical data of 20 patients with acute lower extremity arterial embolism and thrombosis admitted to the Department of Vascular Surgery in the People’s Hospital in Gansu Province where the author worked from September 2016 to March 2017, were retrospectively analyzed. All patients were treated with the AngioJet mechanical thrombectomy system. Clinical data of the patients were retrospectively collected. The clinical efficacy of AngioJet mechanical thrombectomy wasanalyzed.ResultsEighteen (90.0%) of the 20 patients successfully completed the mechanical thrombectomy by using the AngioJet System. The mean time for hospital stay and operation was (4.2±1.4) d and (1.3±0.4) h, respectively. The average doses of urokinase and heparin during operation were (35.80±12.30) ×104 U and (45.10±8.30) mg, respectively. Two patients received a complementary treatment of incision for removing the thrombus. Two patients received catheter-directed thrombolysis after the mechanical thrombectomy, 5 patients received bare-metal stent implantation after balloon expansion. Clinical success was in 16 cases. According to the Cooley standard, 10 patients were in excellent condition,6 in good condition, 2 in fair condition, and 2 in poor condition. There were 2 cases of distal arterial embolization,2 cases of antecardial discomfort of bradycardia, and 4 cases of bleeding at the puncture point, but no serious bleeding complications such as gastrointestinal and intracranial hemorrhage occurred. A total of 16 patients presented myoglobinuria during and after operation. All patients were followed up for 6–12 months. The results of ultrasound examination showed that the artery was patency in 15 cases. One patient died of myocardial infarction in 9 months after surgery,2 patients developed lower extremity ischemia symptoms again after surgery, and 2 patients had lower extremity ulcer caused by lower extremity ischemia symptoms. During the follow-up period, no lower limb necrosis, amputation, and death occurred in the remaining patients.ConclusionsThe AngioJet mechanical thrombectomy system is safe and effective. Combined with the use of catheter-directed thrombolysis and stent implantation, the AngioJet mechanical thrombectomy could lead to quick recovery of the perfusion of the lower extremity and improve the limb salvage rates, exhibiting excellent clinical value.
To investigate the value of plasma placental growth factor (PlGF) in percutaneous coronary angioplasty and stent implantation. Methods From May 2006 to March 2007, 61 patients (53 males and 8 females, mean age61 years) and 28 normal controls were included. All patients present with acute chest pain and underwent coronary angiography, the lesion severity of coronary arteries was assessed by Gensini coronary scoring system. Of them, 26 patients having serious coronary lesion underwent (percutaneous transluminal coronary angioplasty, PTCA) and stent implantation. Cardiovascular events were recorded after 30 days. Plasma PlGF was determined by ELISA. Results According to the angiography, the patients could be divided into CAD group (n=45) and Non- CAD group (n=16). Plasma PlGF level in CAD group was significantly higher than that in Non-CAD group and control group [(10.70 ± 0.49) ng/L vs (4.53 ± 0.64) ng/L vs (3.64 ± 0.36) ng/L, P lt; 0.001)], and there was no significant difference between the non-CAD group and control group (P gt; 0.05). A significant positive correlation was found between Gensini coronary score and plasma PlGF level (r=0.918, P lt; 0.01). Moreover, patients with cardiovascular events had a higher PlGF level than those without cardiovascular events after PTCA and stent implantation [(13.98 ± 3.39) ng/L vs (7.25 ± 2.96) ng/L, P lt; 0.01)]. Conclusion PlGF level has diagnostic value in patients with acute chest pain. The measurement of plasma PlGF might be helpful for early diagnosis of coronary artery disease. Patients with higher plasma PlGF level may have more severe coronary lesion. PlGF may be one of predictors for cardiovascular events after PCI.
