【摘要】 目的 探討2型糖尿病合并下肢血管病變血管內介入治療的臨床意義。 方法 2009年1-5月對4例2型糖尿病合并下肢血管病變患者，根據血管狹窄情況選擇不同介入治療方式，行下肢動脈造影及動脈球囊擴張或支架成形術。 結果 4例患者均有表現靜息痛及間歇性跛行，下肢血管超聲顯示糖尿病下肢動脈有不同程度的斑塊、狹窄與血栓形成，病變累及下肢股動脈、髂動脈及脛前、足背動脈。介入治療后患者下肢血管灌注得到明顯改善，靜息痛及間歇性跛行明顯改善，皮溫改善，需要截肢患者截肢平面顯著降低。 結論 通過下肢血管DSA造影檢查，準確了解糖尿病患者下肢血管的阻塞部位及程度，在保守治療基礎上選擇不同方式的介入治療，有助于下肢血管病變的明顯改善。【Abstract】 Objective To investigate the clinical significance of intervention therapy for patients with type 2 diabetes combined with vascular lesions of lower extremities. Methods From January to May, 2009, four diabetic patients with vascular lesions of lower extremities were examined by Doppler ultrasonography and digital subtration angiography (DSA). All patients were treated by percutaneous transluminal angioplasty (PTA) or stenting therapy. Results Stenoses and obstruction of lower extremity blood vessels were observed in all patients. After intervention therapy, vascular perfusion of lower extremities was improved and signs of rest pain and intermittent claudication were relieved; the skin temperature was improved, and the amputation level was apparently decreased. Conclusion It suggests that DSA is effective in judging extend and location of blood vessel stenosis,and the interventional treatment could lead to a satisfying prognosis.
Objective To summarize the experience of emergency coronary artery bypass grafting （CABG） after failed percutaneous coronary intervention. Methods From January 1998 to December 2002, 9 patients underwent emergency CABG after failed percutaneous coronary intervention. The indications of emergency CABG were coronary artery dissection （5 cases）or perforation （2 cases） and acute arterial occlusion （2 cases）. The time averaged 2 hours from onset of ischernia to revascularization. The CABG was performed under off-pump bypass in 3 cases and under CPB in 6 cases. The mean graft number was 3. Results There were no hospital death. The mean follow-up was 17 months. No death and angina occurred. The function of New York Heart Association class Ⅰ-Ⅱ were in 8 patients, class Ⅲ in 1 patient. Conclusion Emergency CABG is an effective management for failed percutaneous coronary intervention if the indication is right.
Objective To investigate the clinical therapeutic effects on malignant spinal tumors treated by percutaneous vertebroplasty(PVP) under the guidance of the digital subtraction angiography(DSA). Methods A retrospective analysis was performed in 196 patients (99 males and 97 females, aged 23-85 years, averaged 60.4 years) with malignant spinal tumors, who underwent the PVP treatment combined with standard chemotherapy and other comprehensive treatment from January 2002 to January 2005. The malignant spinal tumors had their origins as follows: lung cancer (66 cases), breast cancer (55 cases), liver cancer (19 cases), colon cancer (15 cases), stomach cancer (9 cases), prostate cancer (12 cases), multiple myeloma (16 cases), and malignant lymphoma of the spine (4 cases).The metastatic tumors involved the cervical vertebra (32 cases), thoracic vertebra (93 cases), lumbar vertebra (71 cases), and spinal column, including 1 vertebral segment (135 cases), 2 segments (50 cases), and more than 3 segments (11 cases). During the follow-up survey, changes in the visual analogue pain scale(VAS) and changes in the X-ray measurements of the average anterior height, midline height, and posterior height of the diseased vertebra were observed. Results The follow-up for 6 months to 3 years revealed that the percutaneous vertebroplasty on279 vertebral segments had a success with an operational success rate of 100%. Bone cement was injected into the lesions 1-9 ml per segment of the spine. The postoperative X-ray and CT evaluations revealed that spinal stabilization was obtained in all the patients. After operation, 193（98.5%）patients had an obvious decrease or disappearance of the pain in the lower back, and only 3 (1.5%) patients had no obvious improvement in the pain. There was a significant statist-ical difference in the VAS scores between before operation and after operation (Plt;0.05). There were also significant statistical differences in the average anterior height of the diseased vertebra between before operation and after operation（15.71±2.80 mm vs 16.61±3.01 mm）, in the midline height（13.65±2.93 mm vs 14.52±2.72 mm）, and in the posterior height（23.67±2.81 mm vs 23.70±3.13 mm,Plt;0.05). The patients with lung or liver cancer had a mean survival time of 9 monthsafter PVP; the patients with breast cancer, stomach cancer, prostate cancer, lymphoma, or other metastatic tumors had a mean survival time of 18 months. The patients with multiple myeloma had a mean survival time of 27 months. The differences were statistically different (Plt;0.01). Conclusion PVP under the guidance of the DSA is an easier operation witha small wound and few complications. It can effectively alleviate the patient’s pain due to metastatic spinal tumor, stabilize the spine, improve the patient’s quality of life, and reduce the incidence of paraplegia.
Objective To evaluate the efficacy of statins pretreatment in patients before percutaneous coronary intervention (PCI). Methods Published literature on relevant randomized controlled trials (RCTs) were retrieved via electronic and handsearch in databases CNKI, CBM, MEDLINE and The Cochrane Library from January 1990 to May 2011. The references of these articles were also retrieved. Two reviewers independently identified articles according to the inclusion and exclusion criteria, extracted the data, assess the quality of the included studies, and then conducted meta-analysis using RevMan 5.0 software. Results A total of 10 trials involving 3 012 patients were included. The results of meta-analyses showed that: during the periprocedural period, the trial group had a lower incidence than the control group (98 of 1 514 cases, incidence 6.5%) in periprocedural myocardial infarction with a significant difference (OR=0.43, 95% CI 0.34 to 0.56, Plt;0.000 01). The composite of death, myocardial infarction, or target vessel revascularization in one month, essentially driven by periprocedural myocardial infarction, was reported 6.8% in the trial group and 15.1% in the control group (OR=0.41, 95% CI 0.32 to 0.53, Plt;0.000 01). Conclusion Current evidence supports the effectiveness of statin pretreatment used to reducing the rate of periprocedural myocardial infarction in patients before receiving PCI.
Abstract: Percutaneous balloon pulmonary valvuloplasty (PBPV) has become the first choice for the treatment of pulmonary valve stenosis (PS). PBPV is used not only in the independent way to relieve Milo-Ⅰ amp; Ⅱ type of PS as an alteration of surgery, but also in the combination way with surgical treatment to some multiple or complex congenital heart defect,where it plays a part as a pre-operative appeasement or a co-operative procedure, even a supplementary expedience to some failed surgery post-operatively. In this paper, the anatomic classification of PS, the usage of ultrasounic examination, the indication and contraindication, the method and skill during operation, and the effect evaluation of PBPV are reviewed.
Objective
To analyze the safety and effectiveness of ultrasound-guided thoracoscopic atrial septal defect (ASD) closure.
Methods
We prospectively collected the clinical data of 12 patients with ASD treated by ultrasound-guided thoracoscopic ASD closure in Fuwai Hospital from January to September 2017. The characteristics of the patients' ASD and operation, operation safety and effectiveness, postoperative complications and follow-up results were analyzed.
Results
Among the 12 patients, 10 were successfully treated with ultrasound-guided thoracoscopic ASD closure. Two patients switched to ASD repair under thoracoscopy-assisted cardiopulmonary bypass. The size of the ASD was 17-40 (27.22±8.97) mm and the size of the occluder was 36 (30-42) mm. The average postoperative length of hospital stay was 6 days. There were no complications such as arrhythmia, bleeding and pericardial effusion after operation. The average follow-up was 6 (3-10) months after the operation. During the follow-up, no Ⅲ-degree conduction block, occluder dislocation, residual shunt or cardiac pericardial effusion was found.
Conclusion
Ultrasound-guided thoracoscopic ASD closure is a minimally invasive, safe and effective treatment. This technique provides a new minimally invasive surgical option for patients with large defect diameter and poor edge condition.
