Clinical significance of monitoring coagulation- and fibrinolysis-related indexes during catheter-directed thrombolysis for acute lower-extremity deep venous thrombosis / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the patterns of changes in serum levels of of D-dimer, fibrinogen (FIB) and fibrin degradation product (FDP) during catheter-directed thrombolysis (CDT) in patients with acute lower-extremity deep venous thrombosis (DVT) and explore their clinical significance.</p><p><b>METHODS</b>From June, 2014 to June, 2015, 50 patients with acute lower-extremity DVT received CDT. The serum concentrations of D-dimer, FIB and FDP were measured before, during and after CDT in all the subjects, with 50 healthy subjects serving as the control group.</p><p><b>RESULTS</b>Compared with the control group, the patients in DVT group showed significantly increased serum levels of D-dimer (29.17±38.67 vs 0.21 ±0.27 µg/mL), FIB (3.66±0.95 vs 3.32±0.65 g/L) and FDP (76.14±131.48 vs 1.08±0.73 µg/mL) before CDT (P<0.05). Based on the effect of CDT, the patients with DVT were divided into recanalization group (n=34) and failed recanalization group (n=16), and the patients with recanalization had significantly increased serum concentration of D-dimer and FDP (P<0.05) and decreased FIB level (P<0.05) compared with those with failed recanalization at 24 h of CDT. D-dimer, FDP, and FIB showed no significant changes in the patients with failed recanalization after the procedure (P>0.05). Correlation analysis showed that serum D-dimer (r=0.66, P<0.05) and FDP (r=0.50, P<0.05) at 24 h of the procedure were positively correlated with the outcomes of CDT.</p><p><b>CONCLUSION</b>Serum levels of D-dimer, FIB and FDP are important indicators for evaluating and predicting the effectiveness of CDT in patients with acute DVT.</p>

Treatment of orbital venous malformations with intralesional injection of bleomycin lipiodol emulsion / 中华放射学杂志

5 mm and ≤8 mm in 4 cases.The mean value was 4.2 mm. Four patients noticed reduction in their vision and two had diplopia.Those patients were examined by CT or MR.Direct venography was performed in each patient.After the diagnosis of OVM was confirmed, intralesional injection of BLE was performed.The efficacy of the treatment and complications were observed during the following 8 to 42 months(mean 23 months).Results The BLE were successfully injected in all the patients.All patients had resolution of proptosis and diplopia.Three patients gained improvement of visual acuity.The periorbital swelling occurred in all patients after operation and resolved within 1 week without special treatment.Other complications,such as orbital hemorrhage and periorbital scar,were not observed during following-up.Conclusion Intralesional injection with BLE is convenient,safe and efficient for the treatment of OVM.
