Objective To compare the therapeutic effect of percutaneous transhepatic cholangial drainage (PTCD) and operation drainage for the patients with inoperable malignant obstructive jaundice. Methods A total of 131 patients with inoperable malignant obstructive jaundice were treated in this hospital, in which 102 patients had PTCD by placement of metallic stent and (or) plastic tubes to remove obstruction of bile duct (interventional treatment group). Simultaneously 29 patients were selected for operation by intraexternal drainage (operation drainage group). The patients were followed up for comparison of the serum level of total bilirubin, postoperative complications, average length of hospitalization and average cost between the two groups. Results PTCD was successfully performed in all the patients of the interventional treatment group. There were no significant differences of 50% decrease period of average total bilirubin level or postoperative complications between the two groups (Pgt;0.05). The average length of hospitalization and average cost of interventional treatment group were less than those of operation drainage group (Plt;0.05). Conclusions Compare with operation drainage, interventional treatment can reduce average length of hospitalization and average cost, without increase of postoperative complications, which is a main chance of treatment for malignant obstructive jaundice.
ObjectiveTo evaluate the efficacy and safety of a novel wire for echo-guiding percutaneous atrial septal defect (ASD) closure.MethodsTwenty sheep were randomly divided into two groups, an experimental group and a control group (n=10 in each group). In both groups, an animal model of ASD was established by transthoracic balloon dilatation, and percutaneous closure of atrial septal defect was finished only by echography guiding. The total procedure time, passing time (time needed for the guide wire to enter the left atrium), frequency of delivery sheath dropping into right atrium, frequency of arrhythmias and rate of complications were compared between the two groups.ResultsASD model was uneventfully established in all animals. ASD devices were successfully implanted in all sheep. Compared with the control group, the experimental group had significantly less mean procedure time and mean passing time, lower frequency of guide wire dropping into right atrium and frequency of atrial and ventricular premature contractions, respectively (15.36±4.86 min vs. 25.82±7.85 min, 2.69±0.82 min vs. 5.58±3.34 min, 0% vs. 40.0%, 4.41±2.61 vs. 9.60±3.68, 0.75±0.36 vs. 1.34±0.68; all P<0.05) . Two groups did not have serious complications within postoperative one week.ConclusionThe novel wire system is not only safe and effective in the treatment of ASD occlusion, but also easy to operate.
Hybrid coronary revascularization (HCR) combines the advantages of minimally invasive direct coronary artery bypass grafting (MIDCAB) and percutaneous coronary intervention (PCI), and avoids its relative shortcomings, which has received particular attention in recent years. HCR seems to have become the third revascularization strategy for multi-vessel disease in coronary heart diseases. However, the clinical researches on HCR are still limited. This article will systematically review the comparison of HCR with coronary artery bypass grafting (CABG) and PCI, the results of HCR in specific patients, and the clinical results of different HCR strategies.
Objectives
To systematically review the efficacy and safety of clopidogrel 600 mg and 300 mg loading dose in Chinese patients underwent percutaneous coronary intervention (PCI).
Methods
We searched The Cochrane Library, EMbase, PubMed, CNKI, WanFang Data, CBM and VIP databases to collect randomized controlled trials (RCTs) of the efficacy and safety of clopidogrel 600 mg and 300 mg loading dose in Chinese patients underwent PCI from inception to April, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 14.0 software.
Results
A total of 10 RCTs involving 1 166 patients were included. The results of meta-analysis showed that: the 600 mg loading dose group had lower incidence rate of major adverse cardiovascular events (MACE) in comparison with the 300 mg loading dose group (RR=0.29, 95%CI 0.17 to 0.48, P<0.000 1). However, no significant difference was found in the incidence of major bleeding events within 30 days between two groups (RR=1.64, 95%CI 0.70 to 3.80,P=0.252).
Conclusions
The current evidence shows that in Chinese patients underwent PCI, administration of a 600 mg loading dose of clopidogrel is associated with a lower risk of MACE than is administration of a 300 mg loading dose of clopidogrel, without increasing major bleeding risk in 30 days. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To evaluate the clinical efficacy of two-stage retrograde hybrid repair for acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome. Methods From May 2019 to December 2022, the patients presented with acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome treated in the Department of Cardiovascular Surgery of West China Hospital, Sichuan University were enrolled. After preoperative evaluation, all patients underwent priority emergency interventional surgery to improve distal malperfusion, and then underwent two-stage hybrid surgery to repair proximal aortic lesions. The perioperative clinical and imaging data were retrospectively analyzed. Results Five patients were collected, including 4 males and 1 female, with a median age of 58 years. The main manifestations were lower limb ischemia and renal insufficiency in 3 patients, and poor intestinal perfusion in 2 patients. All patients were given priority to interventional surgery to implant graft stents or bare stents and necessary branch artery intervention, and then successfully performed two-stage hybrid surgery, including type Ⅰhybrid surgery for 2 patients, type Ⅱ hybrid surgery for 1 patient and type Ⅲ hybrid surgery for the other 2 patients, with a success rate of 100.0%. All patients were discharged successfully, and the function of the organs with poor perfusion returned to normal. Only 1 patient recovered to grade 4 muscle strength of the diseased lower limbs upon discharge. No adverse events such as amputation, exploratory laparotomy and intestinal resection or long-term hemodialysis occurred. Conclusion The application of two-stage retrograde hybrid repair in the surgical treatment of acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome is safe and effective, and is helpful to improve the perioperative survival rate, and clinical outcomes of such patients.
Objective
To explore the correlation between gender and long-term prognosis of patients with type-B acute aortic dissection (AAD) after endovascular therapy (EVT).
Methods
From January to December 2012, all patients with type-B AAD undergoing EVT were enrolled by retrospective and observational study. They were divided into male and female groups. Kaplan-Meier analysis was used to analyze the correlation between gender and the cumulative survival rate.
Results
A total of 131 tyep-B AAD patients who had undergone EVT were selected, including 97 males (74.0%), and 34 females (26.0%). The medium follow-up duration was 2.1 years. Smoking history, cholesterol, white blood cell count, hemoglobin, creatinine and uric acid of the patients in males were higher than those in females (P<0.05); while the difference in other indexes were not significant (P>0.05). The inhospital mortality of male patients was 10 (10.3%), and was 3 (8.8%) in female patients; there was no significant difference between the two groups (P=0.803). Kaplan-Meier analysis showed that there was no significant difference in cumulative survival rate between the two groups (84.5% vs. 82.4%; Logrank test χ2=0.023, P=0.880).
Conclusion
No correlation between gender and long-term prognosis in patients with type-B AAD after EVT is found.
ObjectiveTo analyze the short-term clinical efficacy and prognosis of one-stop transcatheter aortic valve replacement (TAVR)+percutaneous coronary intervention (PCI) in the treatment of aortic valve disease with coronary heart disease. MethodsThe clinical data of patients with aortic valve disease complicated with coronary heart disease who underwent one-stop TAVR+PCI treatment at the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from January 2018 to June 2023 were retrospective analyzed. The preoperative and postoperative clinical data were compared, and 1-month follow-up results were recorded. ResultsA total of 37 patients were enrolled, including 22 males and 15 females, with an average age of 69.14±6.47 years. Thirty-six patients recovered and were discharged after the surgery, and 1 (2.7%) patient died during the surgery. Self-expanding TAVR valves were implanted through the femoral artery in all patients. One coronary artery was opened by PCI in 35 (94.6%) patients, and two coronary arteries were opened by PCI in 2 (5.4%) patients. All PCI opened arteries had a stenosis>70%. During the postoperative hospitalization, the complications included pulmonary infection in 11 (30.6%) patients, severe pneumonia in 10 (27.8%) patients, liver function injury in 14 (38.9%) patients, renal function injury in 5 (13.9%) patients, cerebral infarction in 1 (2.8%) patient, atrial fibrillation in 1 (2.8%) patient, ventricular premature beats in 2 (5.6%) patients, atrioventricular block in 2 (5.6%) patients, and complete left bundle branch block in 5 (13.9%) patients. The median postoperative ventilation assistance time was 12.0 (0.0, 17.0) h, the ICU monitoring time was 1.0 (0.0, 2.0) d, and the postoperative hospitalization time was 5.0 (4.0, 7.0) d. There was a significant improvement in the New York Heart Association cardiac function grading after surgery (P<0.001). After surgery, there were 21 (58.3%) patients had minor perivalve leakage, 6 (16.7%) patients had minor to moderate perivalve leakage, and no moderate or above degree of perivalve leakage. After one month of postoperative follow-up, 36 patients showed significant improvement in heart function. There were no patients with recurrent acute coronary syndrome, re-PCI, or cardiovascular system disease related re-hospitalization. ConclusionThe one-stop TAVR+PCI treatment for patients with aortic valve disease and coronary heart disease can obtain satisfactory short-term clinical efficacy, which is worth further trying and studying.
ObjectiveTo summarize our experience of emergency coronary artery bypass grafting (CABG) for the treatment of coronary accidents during percutaneous coronary intervention (PCI).
MethodsFrom January 2011 to January 2013, 30 patients with coronary accidents during PCI from our hospital and other hospitals received surgical treatment in Xinhua Hospital, Medical School of Shanghai Jiaotong University. There were 21 male and 9 female patients with their age of 68±11 (54-84) years. Coronary accidents included coronary artery dissection in 12 patients, coronary artery perforation in 12 patients, acute in-stent thrombosis in 2 patients, dilation balloon rupture in 1 patient and balloon retention in 1 patient, and PCI guidewire retention in 2 patients. Among the 30 patients, 8 patients received intra-aortic balloon pump (IABP) implantation preoperatively. All the patients underwent emergency CABG, including 29 patients undergoing off-pump CABG and 1 patient undergoing CABG on pump with heart beating. The patients' medical history, PCI and surgical records were retrospectively reviewed, and surgical treatment strategies, clinical outcomes and prognosis were summarized.
ResultsThe average number of grafts was 2.8±0.4. Postoperative length of ICU stay was 8.3±4.8 days, and mean hospital stay was 20.3±15.2 days. Postoperative complications included low cardiac output syndrome (LCOS) in 3 patients, tracheotomy in 2 patients, acute renal failure requiring continuous renal replacement therapy in 2 patients, and reexploration for bleeding in 1 patient. Twenty-eight were discharged, 1 patient died of multiple organ dysfunction syndrome caused by LCOS, and another patient died of refractory ventricular fibrillation. A total of 26 patients were followed up for 10.2±8.3 months and 1 patient died of stroke during the following up.
ConclusionEmergency CABG can restore coronary artery blood flow quickly and provide good results for coronary accidents during PCI.
