ABSTRACT
Objective To investigate the risk factors that may induce pneumothorax resulted from subclavian vein puncture during interventional therapy for arrhythmia.Methods The clinical data of 4 351 patients with heart disease,who were admitted to Wuhan Asia Heart Disease Hospital,China,during the period from January 2010 to January 2014 to receive subclavian vein puncture for the performance of radiofrequency catheter ablation or pacemaker implantation,were retrospectively analyzed.The gender,age,presence of chronic obstructive pulmonary disease (COPD) and the shape of clavicle of patients who developed pneumothorax were analyzed,and their relationships with the occurrence of pneumothorax were evaluated.Results Of the 4 351 patients,47 patients developed pneumothorax(1.08％),their age was 12-72 years old with a mean of (47.1±18.4) years old.Among the 47 patients,37 patients were females (78.7％).The angle between clavicle and sternum ＜60°(oblique clavicle) was seen in 27 patients,coexisting COPD was seen in 2 patients.The occurrence of pneumothorax was strikingly higher in females than that in males (OR=2.7,95％ CI=1.4-5.2).In patients with oblique clavicle the risk of pneumothorax was obviously increased (OR=3.5,95％ CI=1.6-7.9) and in patients with COPD the probability of pneumothorax was remarkably increased (OR=2.3,95％CI=1.2-4.7).No special treatment was employed in 5 pneumothorax patients,and the pneumothorax was absorbed by itself.In 19 patients,the pneumothorax was relieved through thoracic puncture and suction.Closed drainage of thoracic cavity was employed in 23 patients.All patients were discharged from hospital with complete rehabilitation.Conclusion Clinically,pneumothorax has been an important clinical problem in interventional therapy.In female patients and in patients who have oblique clavicle or coexisting COPD,pneumothorax is more likely to occur when they receive subclavian vein puncture.
ABSTRACT
Objective To compare the value of pacemaker implantation using the subclavian vein (SCV) puncture and thecephalic vein(CV) cutdown approach.Methods One hundred and forty-six patients were randomized into SCV group (98 patients) and CV group (48 patients).We observed the success rate,surgery duration,fluoroscopy time and complications of the two groups.Results The SCV group had significantly higher success rate,shorter duration of surgery and fluoroscopy than the CV group (success rate:100％ (98/98) vs.89％ (43/48),x2 =10.5,P ＜ 0.05 ; duration of surgery:(118 ± 35) min vs.(256 ± 75)min,t =12.12,P ＜0.01 ; duration of fluoroscopy:(15 ±5) min vs.(35 ± 10) min,t =13.08,P ＜0.01).Both groups had one case who developed compilations which were pocket hematoma and wire electrode dislocation respectively.The rate of complications was not significantly different between the two groups (P ＞ 0.05).Conclusion The SCV approach should be considered a preferable access in pacemaker implantation.
ABSTRACT
Objective The incidence rate of complication during central venous catheterization through internal jugular vein (IJV) and subclavian vein (SV) puncture. Methods Clinical controlled trials about IJV and SV puncture were collected and related literatures were screened according to the criteria of inclusion. The literatures underwent Meta analysis and subsequent analysis of sensitivity. Results A total of 18 literatures were included. Meta analysis indicated that statistical difference existed in the related infection rate [RR=1.74, 95%CI (1.32, 2.30)] and arterial puncture [RR=3.19, 95%CI (1.70, 5.99)], but not in the one-time-puncture success rate [RR=1.06, 95%CI (0.90, 1.24)] between IJV and SV puncture. Conclusions The rate of related infection and arterial puncture was higher by IJV than by SV puncture. But we could not confirm if any difference existed in the one-time-puncture success rate between the two methods. The results still needs evaluation by high-quality randomly controlled experiments.
