RÉSUMÉ
Objective To evaluate the feasibility of beside color Doppler ultrasound-guided popliteal vein catheter in treatment of lower extremity deep venous thrombosis (LEDVT).Methods Data of 50 patients with unilateral LEDVT were reviewed,including 25 cases underwent beside color Doppler ultrasound-guided catheter thrombolytic therapy (catheter thrombolytic group) and 25 cases underwent systemic thrombolysis and anticoagulant therapy (anticoagulant thrombolysis group).The cure rate,hospitalization time and the bilateral diameter differences were compared between the 2 groups.Results Thrombolytic effective rate was 100％ in both the 2 groups.Thirty patients were clinical cured,including 22 cases in catheter thrombolytic group and 8 cases in anticoagulant thrombolysis group.The cure rates were significantly different between the 2 groups (88.00％ [22/25] vs 32.00％ [8/25],x2 =16.333,P＜ 0.001).The hospitalization time of catheter thrombolytic group ([12.32 ± 1.49] days) was shorter than that of anticoagulant thrombolysis group ([16.44±2.95]days;t=-6.426,P＜0.001).The diameter differences between LEDVT side and contralateral side of the upper and lower 15 cm form knees in catheter thrombolytic group showed no statistical difference compared with anticoagulant thrombolysis group before the treatment (both P＞0.05),while of catheter thrombolytic group were smaller than those of anticoagulant thrombolysis group after the treatment (both P＜0.05).And the bilateral diameter differences before the treatment were larger than those after the treatment in both groups (all P ＜ 0.05).Conclusion Both of beside color Doppler ultrasound-guided catheter thrombolytic therapy and systemic thrombolysis and anticoagulant therapy can be used to treat LEDVT,while the efficacy of ultrasound-guided catheter thrombolytic therapy is better.
RÉSUMÉ
Objective To investigate the value of cystic adenomatoid malformation volume ratio (CVR) using prenatal ultrasound in evaluation of congenital pulmonary sequestrations (PS) prognosis in fetus.Methods Totally 88 cases of fetal PS diagnosed with prenatal ultrasound were enrolled.The fetal CVR were recorded,and the clinical outcomes were observed.The fetus were further divided into CVR≥1.6 group and CVR＜1.6 group,then the fetal hydrops rate,incidence of respiratory distress symptoms after birth and perinatal infant survival rate between two groups were compared.Results In 88 cases,prenatal ultrasound diagnosed intralobar pulmonary sequestration (ILS) type in 62 cases (62/88,70.45％),extralobar pulmonary sequestration (ELS) type I in 19 cases (19/88,21.59％),and ELS type Ⅱ in 7 cases (7/88,7.95％).There were 81 (81/88,92.05％) live births,5 (5/88,5.68％) of induction,and 2 (2/88,2.27％) of intrauterine fetal death,respectively.In 44 cases of CVR≥1.6 group,36 cases (36/44,81.82％) had respiratory symptoms after birth,and 39 (39/44,88.64％) had combined fetal hydrops.The live birth rate was 84.09％ (37/44).In 44 cases of CVR＜1.6 group,3 cases (3/44,6.82％) had respiratory symptoms after birth and 3 (3/44,6.82％) had combined fetal hydrops.The live birth rate was 100％ (44/44).The fetal hydrops rate,incidence of respiratory symptoms after birth and perinatal infant survival rate were statistically different between the two groups (all P＜0.05).Conclusion Prenatal ultrasound CVR is an effective index for screening and assessing the prognosis in fetus with PS.
