Résumé
Objective To investigate the causes and factors of hemoglobinuria in patients with thrombosis after AngioJet mechanical thrombectomy.Methods The clinical data of 16 patients with thrombosis treated by AngioJet thrombectomy system were retrospectively analyzed.Nine patients with hemoglobinuria during the procedure were included in group A,while 7 patients without hemoglobinuria in group B.The type of surgical procedure,time of intraoperative aspiration and the thrombus volume were compared between both groups.Results Nine (9/16,56.23 ％) of 16 patients were found hemoglobinuria during and after AngioJet mechanical thrombectomy.There were no statistically significant differences in surgical approaches (x2 =1.667,P=0.197),the time of intraoperative aspiration ([320.11±108.80]s vs [265.29±31.46]s,t=0.741,P=0.457),the thrombus volume (x2=0.442,P=0.506) between both groups.No renal function failure were noted directly relating to the use of the AngioJet thrombectomy device.Condusion There are many factors influenced the occurrence of hemoglobinuria in the patients after AngioJet thrombectomy.It can be reduced by using reasonable type of intraoperative aspiration,controled time of aspiration and active perioperative symptomatic treatment.
Résumé
Objective To explore the efficacy of multiple interventional models combined through anterior tibial veins approach in treatment of acute deep venous thrombosis (DVT).Methods The clinical data and the imaging materials of 10 patients with acute DVT were analyzed retrospectively,and the interventional treatment strategies were discussed.Results The percutaneous mechanical thrombectomy (PMT) was performed after a temporary inferior vena cava filter implanted in all patients,and thrombus clearance rate of grade Ⅲ was obtained in 7 patients while 3 patients reached grade Ⅱ criteria.There were 7 patients underwent angioplasty,then the inferior vena cava filter was retrieved during the same procedure in 5 patients while 4 patients in the second stage and 1 patient rejected to retrieve the filter.All swelling limbs alleviated significantly after those procedures.There was no critical complications occured.The total hospital stay ranged from 4 to 7 days,with a mean time of (6.00±0.94) days.All patients were followed up with a mean time of (3.60± 1.84) months (ranged from 1 to 6 months).No thrombus recurrences of the previously affected vessels were reported.Conclusion The multiple interventional models combined via anterior tibial veins for acute DVT is simple,safe and effective,combined with mechanical thrombectomy device can reduce thrombus burden quickly,and combined with angioplasty can consolidate the therapeutic effect,all those methods combined can shorten the overall hospitalization time.
Résumé
Objective To investigate the relationship between the cerebral circulation time and disease condition and prognosis in patients with acute subarachnoid hemorrhage. Methods DSA were performed to determine the cerebral circulation time (CCT) in 60 patients who had subarachnoid hemorrhage (SAH) within 3 days. The patients were divided into different groups according to the severity of the disease condition,patients with CSC score as 13-15 were assigned as group Ⅰ ,whose CCT was (13.45 ± 1. 89) s. Twenty two patients with GSC score as 3-12 were assigned as group Ⅱ ,whose CCT was (16.79 ± 2. 07) s. There were significant difference between the CCT of the two groups (t =3. 76,P = 0. 001). (2)Twenty-nine patients with Hunt-Hess grade as 1-2 were assigned as group 1,whose CCT was (13.06 ± 1. 83) s. Thirty one patients with Hunt-Hess grade as 3-5 were assigned as group 2, whose CCT was (15. 89 ± 2.06) s. There were significant difference between the CCT of the two groups (t = 3. 39, P =0. 003). (3) Seventeen patients with delayed ischemic damage were assigned as group A, whose CCT was (16. 84 ±1.91) s. Forty three patients without delayed ischemic damage were assigned as group B, whose CCT was (12.94 ± 1. 67) s. There were significant difference between the CCT of the two groups (t = 2. 23, P =0.025). (4)Forty-six patients with GOS score as 4-5 were assigned as group a,whose CCT was (13.07 ±1. 89)s. Fourteen patients with GSC score as 1-3 were assigned as group b,whose CCT was (17.11 ± 1. 71)s. There were significant difference between the CCT of the two groups (t = 3. 27, P = 0.008). Conclusion CCT may reflect the severity of the SAH in early onset patients and has prognostic value.
