ObjectiveTo investigate the significance of catheter thrombolysis combined with one-stage iliac vein percutaneous transluminal angioplasty (or stent implantation) in the treatment of acute left lower extremity deep venous thrombosis secondary to Cockett syndrome.MethodsForty-one cases of Cockett syndrome complicated with acute left lower extremity deep vein thrombosis were retrospectively analyzed and summarized in our hospital from January 2016 to June 2019. Catheter directed thrombolysis was performed under the protection of filter, and percutaneous transluminal angioplasty or stent implantation was performed in the first stage of the iliac vein stenosis or occlusion after thrombolysis. Compared the circumference of upper and lower legs of 15 cm above and below patella of the healthy and affected limbs, before and after treatment, and analyzed the venous patency rate.ResultsThe average time of using thrombolytic catheter were (7±3) days, and the average dosage of urokinase was (358.32±69.38) ×104 U. A total of thirty-five Bard stents were implanted (35 cases), four cases underwent percutaneous transluminal angioplasty, and two cases gave up treatment. Before and after treatment, the circumference difference of the higher leg, the circumference difference of the lower leg, and the venous patency were significantly different before and after thrombolysis (P<0.01). The venous patency rate was 58%–75% in this group, and the average venous patency rate was (61±10)%. There was no severe bleeding complication occurred. Thirty-five patients were followed up for 3–26 months, the preservation rate of the valve was 82.86% (29/35), and the first patency rate of iliac vein was 100% (39/39). During the follow-up period, thrombosis recurred in one case of untreated iliac vein, and acute thrombosis in the right side of one case was caused by long iliac vein stent entering the inferior vena cava. No pulmonary embolism was found.ConclusionOn the basis of catheter thrombolysis, one stage removal of iliac vein obstruction in the treatment of acute left lower extremity deep venous thrombosis can relieve the clinical symptoms, reduce the recurrence rate of thrombosis, and reduce the occurrence of deep vein thrombosis syndrome after catheter thrombolysis.
Objective To evaluate the flushing effects of normal saline (NS) and heparin saline (HPS) after central venous catheterization. Methods We searched PubMed, EMbase, The Cochrane Library (Issue 12, 2015), CBM, CNKI, VIP and WanFang Data to collect randomized controlled trials (RCTs) on the flushing effects of NS versus HPS after central venous catheterization from inception to December 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then RevMan 5.3 software was used for meta-analysis. Results A total of 12 RCTs involving 2 092 patients were included. The results of meta-analysis showed that no significant differences were found between the two groups in occlusion rate (OR=1.58, 95%CI 0.79 to 3.14,P=0.19) and the catheter days (OR=–7.24, 95%CI –22.90 to 8.41,P=0.36), while the HPS group had more advantage than the NS group in decreasing the incidence of phlebitis (OR=2.57, 95%CI 1.52 to 4.34,P=0.000 4). Subgroup analysis revealed that HPS provided more superiority over NS in lessening the occlusion rate (OR=1.85, 95%CI 1.22 to 2.80,P=0.004), no significant difference was found when comparing NS to 10 units, and 100 units HPS (10 units: OR=1.51, 95%CI 0.94 to 2.43,P=0.09; 100 units: OR=1.51, 95%CI 0.63 to 3.60,P=0.09). Conclusion HPS appears to be more beneficial than NS, larger rigorously studies are needed for better understanding on the effects of NS and HPS.
Objective To evaluate the therapeutic efficacy of percutaneous transhepatic portal vein catheterization and thrombolysis on acute superior mesenteric vein thrombosis. Methods The treatment and therapeutic efficacy of 7 cases of acute superior mesenteric vein thrombosis underwent percutaneous transhepatic portal vein catheterization and thrombolysis under ultrasound guidance from August 2005 to April 2009 were analyzed. Results All the patients succeeded in portal vein catheterization and no bile leakage or abdominal bleeding occurred during the procedure. The clinical symptoms such as abdominal pain, abdominal distension， and passing bloody stool relieved were relieved and liquid diet began at postoperative of day 2-5. Emergency operation was done in one case and there was no intestinal fistula. The angiography after the operation showed that the majority of thrombosis were cleared and the blood of portal vein and superior mesenteric vein flowed smoothly. During the follow-up of 3 months to 3 years, all the patients’ status maintained well and no recurrence occurred. Conclusion Treatment of acute superior mesenteric vein thrombosis by percutaneous transhepatic portal vein thrombolysis is safe and effective.
ObjectiveTo analyze therapeutic effect of ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage in treatment of granulomatous mastitis (GM).MethodsThe clinical data of 120 patients with GM from January 2018 to December 2018 in the Renmin Hospital of Wuhan University were analyzed. Sixty patients were treated with the ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage (control group), and the other 60 patients were treated with the metronidazole solution combined with dexamethasone on the basis of the control group (observation group). The therapeutic period, total effective rate, postoperative appearance of breast, and recurrence rate were analyzed. While the pathogenic bacteria was analyzed by the microbial culture and the pathogen gene detection.ResultsThere were no significant differences in the baseline data between the two groups (P>0.05). The ultrasound-guided vacuum-assisted rotary excisions were successfully performed in all 120 patients. The therapeutic period of the observation group was shorter than that of the control group (t=–3.633, P<0.001). The total effective rate and rate of excellent and good of postoperative breast appearance had no significant differences between the two groups (total effective rate: 96.7% versus 90.0%, χ2=1.922, P=0.166; rate of excellent and good of postoperative breast appearance: 96.7% versus 88.3%, χ2=1.205, P=0.272). The recurrence rate of the observation group was lower than that of the control group (χ2=5.175, P=0.023). The positive rates of bacteria were 25.8% and 58.8% in the 120 cases by the microbial culture and 52 cases by the pathogen gene detection, respectively, which had a statistical difference (χ2=16.974, P<0.001), the same conclusions were obtained in the observation group and the control group (χ2=6.691, P=0.010; χ2=9.379, P=0.002).ConclusionsUltrasound-guided vacuum-assisted rotary excision with tube irrigation drainage is well applied in treatment of GM. It could maintain a good shape of breast. Use of metronidazole solution combined with dexamethasone after surgery could shorten therapeutic period and reduce recurrence rate.
