Objective
To summarize the clinical features, diagnosis, and treatment of acute deep venous thrombosis (DVT) at lower extremity of aged patients.
Method
Clinical data of 98 aged patients with acute DVT at lower extremity who got treatment in our hospital from Junuary 2012 to December 2014 were analyzed retrospectively.
Results
Of 98 aged patients with acute DVT at lower extremity, the time from disease developed to treatment was 1 day to 10 days with an average of 4 days. The main symptom was low limb swelling progressively. All the patients were treated by the comprehensive treatment based on individual anticoagulation. A total of 96 patients (98.0%) were followed up, and the follow-up period ranged from 12 months to 24 months (average of 18 months). Of 96 patients followed-up, we found a statistically significant difference between lower extremities before treatment and those at 3 months after treatment in venous clinical severity score (VCSS) and the change of lower extremity circumference (P<0.001). Of 96 patients, 9 patients were cured, 81 patients had markedly effective results, and 6 patients had effective results. None of the patients suffered from fatal pulmonary embolismin in duration of hospital day and follow-up period, and no one suffered form DVT recurrence.
Conclusions
The aged patients with acute DVT at lower extremity usually see a doctor lately. The comprehensive treatment based on individual anticoagulation is safe and effective in treatment of acute DVT at lower extremity of aged patients.
ObjectiveTo systematically evaluated the efficacy of AngioJet mechanical thrombectomy and catheter-directed thrombolysis (CDT) in the treatment of acute lower extremity deep venous thrombosis (LEDVT).MethodsAccording to the retrieval strategy of Cochrane collaboration network, the relevant literatures in CNKI, WangFang, VIP, CBM, PubMed, Embase, Cochrane Library, Web of Science at home and abroad up to March 25, 2020 were collected, and the meta analysis was performed by using Review Manager 5.3 software.ResultsA total of 20 observational studies were included in the meta analysis. The total number of patients was 1 566, which 799 cases in the AngioJet group and 767 cases in the CDT group. The results showed that the AngioJet group had a higher patency rate of deep vein ［MD=11.34, 95%CI (6.16, 16.51), P<0.000 1］, lower or shorter Villalta score ［MD=–1.90, 95%CI (–2.71, –1.10), P<0.000 01］, incidence of post-thrombotic syndrome［PTS, OR=0.42, 95%CI (0.23, 0.77), P=0.005］, rate of clot reduction grade Ⅰ events ［OR=0.40, 95%CI (0.24, 0.67), P=0.000 5］, incidence of bleeding complication ［OR=0.32, 95%CI (0.21, 0.49), P<0.000 01］, and hospital stay ［MD=–2.96, 95%CI (–3.69, –2.22), P<0.000 01］.ConclusionsIn the early efficacy, AngioJet mechanical thrombectomy has better patency rate of deep vein and thrombolysis, shorter hospital stay, and lower risk of bleeding than CDT. In the mid-term effect, AngioJet mechanical thrombectomy could reduce the incidence and the severity of PTS.
Objective To explore the therapeutic effect of catheter-directed thrombolysis combined with vena cava filter on deep venous thrombosis (DVT) of lower extremity.Methods The clinical data of 65 patients with DVT of lower extremities from January 2008 to August 2009 were analyzed retrospectively, whose course of diseases were not more than 7 d and clinical type included central type and mixed type. Thirty-two cases were treated with catheter-directed thrombolysis combined with vena cava filter, while administrating treatment of anticoagulation and activating blood circulation to dissipate blood stasis, which were named as study group. Thirty-three cases were treated traditionally with thrombolysis, anticoagulation, and activating blood circulation to dissipate blood stasis, which were named as control group. The course of therapy was continued 10-14 d, then the efficacy in two groups patients was evaluated. Results It was (7.35±1.42) cm that circumference difference before treatment between affected extremties and unaffected extremties in study group, which of 3, 7, and 14 d after treatment was (4.21±1.12) cm， (2.87±0.98) cm, and (1.22±1.02) cm, respectively. Circumference difference between before and after treatment had significant difference in study group (Plt;0.01). It was (6.97±1.27) cm that circumference difference before treatment between affected extremties and unaffected extremties in control group, which of 3, 7, and 14 d after treatment was (5.72±1.31) cm, (4.58±0.88) cm, and (3.18±1.24) cm, respectively. Circumference difference between before treatment and 3, 7, and 14 d after treatment had significant difference in control group (Plt;0.05 or Plt;0.01). Circumference difference before treatment in two groups had no significant difference (Pgt;0.05). Circumference difference after treatment at different time points in two groups was significantly different, respectively (Plt;0.01). Circumference difference after treatment at different time points in study group was significantly less than that in control group, respectively (Plt;0.01). After 14 d, complete recanalization rate （71.88%, 23/32） and cure rate (71.88%, 23/32) of iliofemoral vein in study group were significant higher than that (36.36%, 12/33) in control group (Plt;0.01). No pulmonary embolism occurred. Conclusion In terms of ideal therapy targets of DVT of lower extremity, the catheterdirected thrombolysis combined with vena cava filter is obviously superior to traditional thrombolysis treatment.
ObjectiveTo compare the differences of incidence rate and severity of postthrombotic syndrome (PTS) of patients with lower extremity deep venous thrombosis (DVT) treated by catherter-directed thrombolysis (CDT) or via peripheral vein thrombolysis (PVT).MethodsThe patients with unilateral lower extremity DVT who had received anticoagulant and thrombolytic therapy in the Nanchong Central Hospital from January 2012 to January 2015 were collected. These patients were divided into CDT group and PVT group according to the different thrombolysis methods, and then the thrombolytic rates, thrombolytic complications, and the incidence rate and severity of PTS of 5-year follow up results were calculated and compared.ResultsA total of 137 cases of DVT were collected, 79 in the CDT group and 58 in the PVT group. There were no significant differences in the gender, age, course of disease, thrombus type, and other baseline data between the two groups (P>0.05). The thrombolytic rate of the CDT group was (78.6±16.3)% and PVT group was (27.3±12.1)%, the difference was significant (t=21.14, P<0.001). The rate of thrombolytic complications between the PVT group and CDT group had no statistical significance (32.8% versus 21.5%, χ2=2.18, P=0.134). The 5-year follow up was completed in 116 cases, 74 patients from the CDT group and 42 patients from the PVT group respectively, the result showed that the incidence rate of the PTS in the CDT group was lower than that in the PVT group (35.1% versus 88.1%, χ2=30.28, P<0.001), and theseverity of PTS in the CDT group was milder than that in the PVT group too (Z=16.52,P<0.001).ConclusionFrom the results of this study, CDT is able to increase thrombolytic rate and effectively reduce incidence rate and severity of PTS.
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.
ObjectiveTo summarize strategy of diagnosis and treatment of thrombotic iliac vein stenosis in recent years.MethodThe relevant literatures in recent 5 years on the current status and trend of diagnosis and treatment of the thrombotic iliac vein stenosis were reviewed.ResultsAt present, the diagnostic methods of thrombotic iliac vein stenosis mainly included that the multi-slice spiral CT, venography, intracavitary ultrasound, magnetic resonance imaging, color Doppler ultrasound and other imaging examinations, each of which had its advantages and disadvantages. There were still no uniform criteria whether a filter should be placed, whether the stents should and how to be placed, and when to intervene in the patients with acute thrombotic iliac vein stenosis. There was no definite conclusion when and how to effectively intervene in the patients with chronic thrombotic iliac vein stenosis.ConclusionsIncidence of thrombotic iliac vein stenosis is high and sequela is severe. Early diagnosis and reasonable treatment are very important. Only strictly grasping indications, combining medical technology and patient’s condition, and adopting appropriate treatment strategy, can make patients’ maximal benefit.
Objective
To summarize the research about the stability of deep venous thrombosis (DVT) of the lower extremity in recent years.
Methods
The literatures about the stability of DVT of lower limbs at home and abroad in recent years were reviewed.
Results
There are few studies on the stability of DVT at home and abroad, which limited on the floating thrombus.
Conclusion
The stability of DVT can be effectively evaluated by SOMATOM Force CT (The third generation dual source CT).
Objective To study the significance of the levels of plasma inflammatory cytokines (IL-6，IL-8，IL-10 and TNF-α) in patients with acute deep venous thrombosis (DVT) of lower extremity. Methods Forty untreated DVT cases were selected as the subjects in the DVT group, while thirty healthy subjects, whose ages and genders showed no significant difference with the DVT patients, were collected as the control group. The plasma levels of IL-6, IL-8 and TNF-α were detected by radioimmunoassay (RIA), and the plasma level of IL-10 was measured by enzyme-linked immunosorbent assay (ELISA). Correlation analysis was used to investigate the relationships between the levels of different inflammatory cytokines within DVT group. Results The levels of plasma cytokines in the DVT group were all significantly higher than those in control group (P＜0.001). The results of the correlation analysis showed that there were positive correlations between IL-6 and TNF-α (r=0.383, P＜0.05), IL-10 and TNF-α (r=0.390, P＜0.05), respectively, within the DVT group; whereas there were no correlations between IL-6 and IL-8, IL-6 and IL-10, IL-8 and IL-10, and IL-8 and TNF-α. Conclusion The levels of plasma cytokines increased significantly in patients of DVT. Inflammatory cytokines may play an important role in acute DVT by accelerating the pace of thrombosis, intensifying the inflammatory reaction around thrombus and aggravating the injured blood vessel.
ObjectiveTo evaluate the value of clinical application of determination of lower venous pressure in the diagnosis and treatment of deep venous thrombosis (DVT).
MethodsThe 90 patients with DVT of unilateral lower limb who were admitted by using color Doppler or deep veins of lower limb angiography in our hospital during the period of 2013 July to 2014 June were selected and as the research object (case group), 37 cases were male, 53 cases were female; the age was 18-84 years old, mean age was 59.48 years old. According to the development of disease, 90 cases were divided into acute 30 cases, subacute 30 cases, and chronic 30 cases; and according to the pathological types were divided into the central type in 30 cases, 30 cases of peripheral type, and 30 cases of mixed type. At the same time the without lower extremity DVT volunteers of 20 cases were selected as normal control group, including male 9 cases, female 11 cases; age was 21-65 years old, average age was 38.7 years old. The static venous pressure (P0), dynamic venous pressure (P00), and decreased pressure ratio (Pd) of double lower limbs of participants in 2 groups were determinated and comparative analyzed.
ResultsThe P0 and P00 of patients with different development of disease and pathological types of the case group were higher than those of the normal control group (P < 0.01), and the Pd was lower than that of the normal control group (P < 0.01). In case group, the P0 and P00 of acute phase were higher than those of the normal control group (P < 0.01), the P0 of central type was higher than that of the peripheral type and mixed type (P < 0.01), and the Pd central type was lower than that of mixed type (P < 0.01). The above 3 indexes' differences of double lower limbs in the normal control group had no statistical significance (P > 0.01). In case group, the P0 and P00 of ipsilateral limb in different development of disease and pathological types were higher than those of the healthy limb, and the Pd were lower than that of the healthy limb (P < 0.01).
ConclusionsLower extremity venous pressure measurements can be used in clinical detection for early lower limb DVT, and can be used as the objective index of clinical evaluation curative effect for the treatment of DVT. It is a simple and practical clinical detection method.
ObjectiveTo investigate the effects of intraoperative intermittent pneumatic compression (IPC) treatment on coagulation and fibrinolysis, lower extremity venous blood flow velocity, and deep venous thrombosis (DVT) in patients with gastric cancer (GC) after radical gastrectomy. MethodsThe patients with GC who underwent radical gastrectomy at Hebei Provincial People’s Hospital from July 2021 to July 2024 were retrospectively enrolled, then the patients were assigned into control group (the patients who did not receive intraoperative IPC) and study group (the patients who received intraoperative IPC), and the propensity score matching (PSM) method was used to conduct 1∶1 matching based on the basic characteristics such as age, gender, body mass index, comorbidities to ensure baseline comparability between the two groups. The incidences of postoperative DVT and lower extremity swelling, and coagulations [prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT)] and fibrinolysis [D-dimer (D-D), fibrinogen (FIB), and fibrin degradation products (FDP)], as well as lower extremity venous blood flow velocity were analyzed after PSM. The locally weighted regression was used to analyze the correlation between the coagulation and fibrinolytic functions indexes and the lower extremity venous blood flow velocity. ResultsA total of 120 patients were matched (60 cases per group). The baseline characteristics of both groups were comparable (P>0.05). The incidences of DVT on day 7 and lower extremity swelling on day 1, 3, and 7 after surgery in the study group were significantly lower than those in the control group (P<0.05). The results of repeated-measures analysis of variance showed that there were statistically significant differences in the inter-group, time-related, and group-by-time interaction effects of coagulation and fibrinolysis indexes as well as lower extrimety venous blood flow velocities (P<0.05). The impact of the time factor on coagulation and fibrinolysis indexes and lower extrimety venous blood flow velocities varied with intraoperative IPC intervention measures. After surgery, the PT, TT, APTT, and lower extrimety venous blood flow velocities in the study group first decreased and then increased as compared with those before surgery, and the decrease degree was smaller and the increase degree was larger than those in the control group. After surgery, the D-D, FIB, and FDP in the study group first increased and then decreased as compared with those before surgery, and the increase degree was smaller and the decrease degree was larger than those in the control group. Both PT and TT were significantly positively correlated with femoral vein blood flow velocity (r=0.21, P=0.042; r=0.22, P=0.040), and both also showed significant positive correlations with popliteal vein blood flow velocity (r=0.25, P＜0.001; r=0.20, P=0.032). APTT was only significantly positively correlated with popliteal vein blood flow velocity (r=0.33, P＜0.001). D-D was negatively correlated with the flow velocities of the femoral vein, external iliac vein, and popliteal vein (r=–0.23, P=0.012; r=–0.22, P=0.047; r=–0.37, P<0.001). Both FIB and FDP were negatively correlated with the flow velocity of the femoral vein (r=–0.23, P=0.036; r=–0.27, P=0.002). FIB was also negatively correlated with the flow velocity of the popliteal vein (r=–0.26, P=0.038), and FDP was negatively correlated with the flow velocity of the external iliac vein (r=–0.31, P<0.001). ConclusionBased on the results of this study, intraoperative IPC treatment could improve coagulation and fibrinolytic functions of patients with GC after surgery, and has a certain preventive effect on occurrence DVT of lower extremity.
