  • Safety and Efficacy of Intermittent Pneumatic Compression in The Treatment of Deep Venous Thrombosis

    ObjectiveTo investigate the safety and efficacy of intermittent pneumatic compression (IPC) in the treatment of deep venous thrombosis (DVT). MethodsThe clinical data of 496 patients with DVT who were treated in our hospital from January 2010 to October 2014 were analyzed retrospectively, to compare the time of venous pressure decreased to normal (T1) and time of circumference difference decreased to normal (T2) in patients received pure therapy (control group) and pure therapy combined with IPC (combination group), according to different types of patients in acute, sub-acute, and chronic phase. In addition, comparison of the remission rate of pulmonary embolism (PE), incidence of PE, and recurrence of DVT was performed between the control group and combination group too. Results① For DVT patients in acute stage, the time of T1 and T2 of patients in central type, peripheral type, and mixed type who received anticoagulant therapy/systemic thrombolysis/catheter thrombolysis+IPC, were significantly shorter than those patients who received only anticoagulant therapy/systemic thrombolysis/catheter thrombolysis (P<0.05). For DVT patients in sub-acute stage, the time of T1 and T2 of patients in central type and mixed type who received anticoagulant therapy/systemic thrombolysis+IPC, were significantly shorter than those of patients who received only anticoagulant therapy/systemic thrombolysis (P<0.05), the time of T1 of patients in peripheral type who received anticoagulant therapy/systemic thrombolysis+IPC, were significantly shorter than those of patients who received only anticoagulant therapy/systemic thrombolysis (P<0.01), but the time of T2 of patients in peripheral type didn't differed between patients who received only anticoagulant therapy/systemic thrombolysis and anticoagulant therapy/systemic thrombolysis +IPC (P>0.05). For DVT patients in chronic stage, the time of T1 and T2 of patients in central type and mixed type didn't differed between patients who received only anticoagulant therapy and anticoagulant therapy +IPC (P>0.05); the time of T1 of patients in peripheral type who received anticoagulant therapy+IPC, were significantly shorter than those of patients who received only anticoagulant therapy (P<0.05), but the time of T2 didn't differed with each other (P>0.05). ② There were 63 patients in control group and 47 patients in combination group had PE before treatment. After the treatment, the PE symptom of control group relieved in 56 patients (88.89%, 56/63) and maintained in 7 patients (11.11%, 7/63), the symptom of combination group relieved in 44 patients (93.62%, 44/47) and maintained in 3 patients (6.38%, 3/47), so the remission rate of PE symptom in combination group was higher (P<0.05). There were 6 patients suffered from new PE in control group[4.26% (6/141)] and 0 in combination group[0 (0/245)] after treatment in patients who hadn't PE before treatment, and the incidence of PE was lower in combination group (P<0.05). ③ There were 325 patients were followed up for 3-36 months with the median time of 27 months, including 157 patents in control group and 168 patients in combination group. During the follow-up period, 74 patients recurred[47.13% (74/157)] in control group and 46 patients recurred[27.38% (46/168)] in combination group, and the recurrence rate was lower in combination group (P<0.05). In addition, 41 patients suffered from post-thrombotic syndrome[26.11% (41/157)] in control group and 27 patients[16.07% (27/168)] in combination group, and the incidence of post-thrombotic syndrome was lower in combination group (P<0.05). ConclusionsIPC can significantly shorten the time of venous pressure and the circumference difference decreased to normal for DVT patients in acute stage and majority DVT patients in sub-acute stage, and it can relieve the clinical symptoms of PE, reduce the incidence rate of PE and recurrence rate of DVT. Therefore, IPC is a safe, reliable, and effective treatment for DVT patients in acute stage and majority DVT patients in sub-acute stage.

  • Clinical Application of Determination of Lower Extremity Venous Pressure in The Diagnosis and Treatment of Lower Extremity Deep Vein Thrombosis

    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.
