Objective To evaluate the effect and safety of infantile femoral vein blood sampling with vacuum versus disposable needle. Methods Such databases as VIP, CNKI, CBM, Google Academic and Wanfang data were searched to collect the randomized controlled trials (RCTs) about infantile femoral vein blood sampling with vacuum versus disposable needle published from January 2000 to July 2010. The studies were screened according to the inclusive and exclusive criteria, the data were extracted, the methodology quality was assessed, and meta-analysis was conducted by using RevMan 5.0 software. Results A total of 15 RCTs were included. Of 3 490 patients in all, 1 770 were in the treatment group and 1 726 were in the control group. The baseline conditions were reported in 14 studies, and the random methods were mentioned in 11 RCTs. All studies didn’t report the allocation concealment and blind method. Only 2 RCTs reported separately that, the degree of neonatal pain was lower in the treatment group (Plt;0.01), and the satisfaction of parents was higher in the treatment group (Plt;0.01). Four RCTs compared the sampling time between the two groups without meta-analysis mentioned due to the disunity of standard, only the descriptive outcomes showed a shorter time in the treatment group. The meta-analysis showed that, compared with the control group, the reject rate of sample quality was lower (RR=0.20, 95%CI 0.15 to 0.26), the success rate of one time sampling was higher (RR=1.20, 95%CI 1.16 to 1.24), the injury of local tissue was slighter (RR=0.62, 95%CI 0.45 to 0.86), and the iatrogenic contamination was lower (RR=0.62, 95%CI 0.45 to 0.86) in the treatment group. Conclusion This review shows that the vacuum sampling is superior to the disposable needle sampling for domestic infantile femoral vein blood collection. Due to the low quality of the included studies with high possibility of bias, this conclusion needs to be further verified by performing more high-quality studies.
【Abstract】 Objective To explore the feasibility and safety of the femoral vein as a vascular graft material. Methods A total of 114 specimens of lower limbs were harvested from 60 adult cadavers; the lower extremity femoral veins, popliteal vein, deep femoral vein, and the communicating branch were dissected and observed; the length of the available femoral vein, from the point at which deep femoral vein and femoral vein joint to the lower edge of abductor hiatus, and squash vein diameter were measured. Computed tomography venography (CTV) data from 120 patients with lower extremity femoral vein thrombosis were analysed, and the venous reflux pathway of the lower extremity was observed. Results The average height of male was 158.3 cm, and the available length of femoral vein was (18.8 ± 2.3) cm (relative length, 0.118 ± 0.013), and squash vein diameter was (15.8 ± 0.8) mm. The average height of female was 149.2 cm, and the available length of femoral vein was (15.1 ± 1.5) cm (relative length, 0.101 ± 0.010), and squash vein diameter was (14.0 ± 1.1) mm. There were significant differences in the length of the available femoral vein (t=6.354, P=0.000) and squash vein diameter (t=5.555, P=0.000) between male and female. Positive correlation was found between the length of the available femoral vein and height (r=0.964, P=0.000). Low correlation was found between squash vein diameter and height (r=0.382, P=0.003). Double femoral veins were found in 16 limbs (14.0%), a femoral-popliteal vein communicating branch in 48 limbs (42.1%), a deep femoral-popliteal vein communicating branch in 38 limbs (33.3%). CTV showed that great saphenous vein, femoral-popliteal, or deep femoral-popliteal vein communicating branches had compensative capacity in patients with femoral vein thrombosis. Conclusion It is reliable and safe to harvest femoral vein as a vascular graft because of the existence of the great saphenous vein and communicating branches between the popliteal vein and femoral vein or deep femoral vein.
Objective To introduce the application of transcatheter closure of multi-fenestrated atrial septal defect (ASD) via femoral vein under ultrasound guidance with amplatzer cribriform occluder (ACO) and atrial septal defect occluder (ASDO), as well as to assess its feasibility, effectiveness and safety. Methods The clinical data of 48 patients with fenestrated ASD occluded via femoral vein under ultrasound guidance from December 2015 to May 2018 in our hospital were retrospectively analyzed, including 17 males and 31 females, aged 10 months to 51 years, an average of 11.50±13.86 years, and weighting 6-79 (27.00±20.14) kg. Among 48 patients with fenestrated ASD, 12 patients had double-foramen and 13 atrial septal aneurysm combined with defects and 23 multi-foramen. All patients underwent transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE) to complete the closure of fenestrated ASD. Ultrasound, electrocardiogram and chest X-ray were reviewed the next day after surgery to evaluate the curative effect. Results Forty-eight patients with ASD were treated with 49 occluders, due to one patient with two occluders. There were 29 ASDO (8-26 mm) and 20 ACO (18-34 mm). During the operation, TTE/TEE examination showed that 48 patients were completely occluded, 13 patients showed fine bundle shunt in the unreleased push notification rod, and 9 patients had fine bundle shunt after the release of push notification rod. Fine bundle shunt was found in 8 patients 24 hours after operation, and microshunt was found in 3 patients 1 year after operation. All the patients were followed up. The occluder position was good. The right heart was reduced in different degrees, and the X-ray showed that the pulmonary blood was reduced in different degrees. No arrhythmia was found by electrocardiogram after operation. Conclusion It is a safe and effective method to use ACO and ASDO to occlude ASD through femoral approach under ultrasound guidance.
Objective To evaluate the clinical effect of staging endovascular angioplasty in treatment for iliofemoral venous post-thrombotic syndrome （PTS）. Methods The clinical data of 45 patients with iliofemoral venous PTS from May 2008 to October 2011 in this hospital were analyzed retrospectively. After the identification of the stenosis or occlusion by angiography via femoral vein by percutaneous puncture or incision puncture， recanalization of the occlusion was done by guide wire. Then the percutaneous transluminal angioplasty （PTA） was performed. Results A total of 45 cases （45 legs） had been undergone PTA. The procedures were technically successful in all the patients. No serious complications such as lumen rupture happened. Follow-up time was 6-30 months with （18.06±3.12） months， the symptoms of the affected limb were obviously relieved in 31 cases， partly relieved in 10 cases， not relieved in 4 cases. Reexamination of venous angiography， 9 cases were cured， 18 cases were excellent， 14 cases were improved， 4 cases were ineffective. The total effective rate was 91.11% （41/45）. Conclusion PTA is a safe and effective method in treatment for iliofemoral venous PTS.
Reoperation due to degenerated bioprostheses is an important factor of high-risk thoracic surgeries. In 2020 ACC/AHA guideline, Valve in Valve (ViV) was recommended for high-risk patient instead of surgical mitral valve replacement. This report described a 77-year-old male patient with a failed mitral bioprosthetic valve, evaluated at high risk of surgery, received a transvenous, transseptal transcatheter mitral valve replacement (TMVR). Tracheal intubation was removed at CCU 3 h after surgery without discomfort such as polypnea. The patient was transferred out of the CCU and discharged on the 3rd day. Compared with transapical access, transvenous transseptal access was less invasive, with shorter duration in CCU and hospitalization.
ObjectiveTo analyze the efficacy and safety of percutaneous balloon pulmonary valvuloplasty (PBPV) for pulmonary valve stenosis guided by ultrasound.MethodsFrom March 2016 to July 2019, 32 patients with pulmonary valve stenosis were treated in our hospital. There were 19 males and 13 females with an average age of 1-12 (6.2±3.1) years and weight of 7-45 (22.7±9.2) kg. The clinical efficacy of PBPV guided by transthoracic echocardiography (TTE) was evaluated.ResultsThe transvalvular pressure gradient (PG) of the patients before PBPV was 65.4±11.9 mm Hg. All patients successfully received PBPV under TTE guidance. The PG was 19.7±4.0 mm Hg immediately after operation, which was significantly decreased (P<0.001). All patients survived without any serious complications. The PG values at 3 months, 6 months and 12 months after operation were 18.4±4.0 mm Hg, 16.4±3.9 mm Hg, 15.2±3.3 mm Hg, respectively, which were significantly lower than that before the operation (P<0.001).ConclusionPBPV guided by echocardiography is safe and effective in the treatment of pulmonary valve stenosis with low complications rate.
Mitral regurgitation (MR) is the most common valvular heart disease, however, majority of patients are not suitable for open heart surgery due to comorbidity such as organ and heart dysfunction. Transcatheter edge-to-edge mitral valve repair has become an effective treatment option for high-risk patients with MR. Two patients were enrolled in this study inlcuding one 60-year degenerative mitral regurgitation patient and one 72-year functional mitral regurgitation patient. Transcatheter repair procedure was successfully done for the two patients without postoperative complication.
Objective To study the effectiveness of substitute valve at the popliteal vein in treatment of deep venous valve insufficiency of lower extremities. Methods From January 1996 to August 2002, 27 patients were diagnosed having deep venous valve insufficiency of lower extremities by color Doppler and radiography with an average disease course of 17.4 years.All 27 patients had varicose vein, 25 pain, 22 swelling,25 pigmentation in ankle area and 19 chronic ulcerations.Two cases had been treated with great saphenous vein ligation and striping.Averagevein pressure in resting position was (11.00±0.73)kPa,and the ambulatory venous pressure was (9.14±0.68)kPa.All patients were treated with substitute valve at the popliteal vein,and great saphenous vein ligation and stripping, some were treated with subfascial endoscopic perforating veins ablation. Results The average ambulatory venous pressure after operation was (5.94±0.82)kPa,were significantly different from that before operation(P＜0.01). The curative results were satisfactory,and all symptom and physical sign disappeared.After a mean follow-up period of2-6 years,21 cases had satifactory results. Conclusion Substitute valve at the popliteal vein have the value of widespread application.
