ABSTRACT
Objective To evaluate catheter thrombectomy,mechanical thromboaspiration and catheter-directed thrombolysis for the treatment of deep venous thrombosis.Methods From January 2015 to February 2016,60 patients with acute deep vein thrombosis were placed the inferior vena cava filter from contralateral femoral vein or right internal jugular vein.A 5 F pigtail catheter was led to the ipsilateral deep vein,bolus urokinase was given and catheter thrombectomy was undertaken and thromboaspiration was carried out using 10-12 F catheter,then through catheter continuous infusion of urokinase.Results 45 cases were cured,8 cases were significantly improved,5 cases were improved,2 cases were judged as ineffective,the effective rate was 96.6％.Before thrombolysis the thigh circumference difference between affected limb and the contralateral limb was (3.6 ± 1.9)cm (P ＜0.05),calf circumference difference was (4.6 ±2.1)cm (P ＜ 0.05);The difference between the affected limb and contralateral thigh circumferences was (0.19±0.90) cm (P ＞ 0.05),calf circumference difference was (0.5 ± 1.0) cm (P ＞ 0.05).Conclusions Catheter thrombectomy,thromboaspiration and catheter-directed thrombolysis for deep venous thrombosis is safe and effective.
ABSTRACT
ObjectiveTo explore the effect of endovascular treatment for closed limb artery trauma. MethodsFrom March 2006 to December 2011,the clinical data of 12 cases treated for closed limb artery trauma were analyzed retrospectively.Catheters sheath were placed by antegrade or retrograde puncture.Catheters was send to the proximal end of the lesion.Intraoperatively through angiography the location and extent of arterial lesions were determined.Catheter with the help of guidewire were sent through the lesion to establish treatment “ pathway,at the lesion site suitable stents were placed to repair damaged arteries. ResultsThe procedure was all successful in 12 patients,there was no mortality nor sever compalications.Postoperatively 2 cases suffered from acute renal failure,and were managed and cured by continuous veno-venous hemofiltration (CWH).Osteofascial compartment incision decompression was carried out in 3 cases due to osteofascial compartment syndrome.One case of them suffered from amputation due to sever muscle necrosis and lost of limb function.Eleven patients were followed-up for 1year.All the arteries were patent.There were no stent break,deformation or stenosis.ConclusionsEndovascular techniques for the treatment of closed limb arterial trauma is safe and effective.
ABSTRACT
ObjectiveTo study the effect of ischemia postconditioning intervention in a rabbit's acute mesenteric ischemia-reperfusion injury model.Methods 120 rabbits were divided randomly into Con( only expose SMA by operation),I/R( clamping SMA 30 min,reperfusing 120 min),IpostC1 ( clamping SMA 30 min,3 clamping 30 s/releasing 30 s round,reperfusing 117 min),and IpostC2 (clamping SMA 30 min,3 clamping 60 s/releasing 60 s round,reperfusing 114 min) group (n =30).Levels of MDA and MPO in serum and intestinal tissues were measured. Chiu-6 standard scoring was used to determine the pathology score of injured intestinal mucosae.ResultsCompared with the Con group,MDA and MPO levels in serum and intestinal tissues increased obviously in the three other groups,the same as in the pathology score of injured intestinal mucosae (P ＜ 0.01 ) ; Compared with the I/R group,the MDA and MPO levels in serum and intestinal tissues decreased obviously in the IpostC1 group ( P ＜ 0.01 ),but not in the IpostC2 group ( P ＞ 0.05 ).ConclusionsMDA and MPO levels in serum and intestinal tissues and intestinal mucosal injury decreased obviously in the rabbit's acute mesenteric ischemia-reperfusion injury model by ischemia postconditioning intervention.
ABSTRACT
Objective Compared with the effect of thromboembolectomy assisted with intraoperative digital subtraction angiography (DSA) and traditional method,evaluate the value of intraoperative DSA on surgical procedures for acute lower limb arterial embolism. Methods Sixeight cases of traditional thromboembolectomy to take on the operation (group A) and 72 cases under the DSA operation (group B)were analyzed during January 2005 to December 2009, Comparing two sets of operation (time, the amount of bleeding and the ankle brachial index changes before and after the surgery , amputations rate). Results The operation time of group B [(76 ±17) min] was less than that of group A [(95 ± 22) min, t =5. 736, P ＜ 0. 01] ; the amount of bleeding of group B [(83 ± 35 ) ml] was significantly less than group A [(102 ± 58 ) ml, t = 2. 362, P ＜ 0. 05]; The difference of ABI in group B after the operation than before (0. 32 ±0. 08) than that in group A(0. 25 ±0. 12) had remarkably improved ( t =2. 33, P ＜0. 05) ;there were 8 patient amputations in group A and 2 in group B ( u = 2. 06 , P＜ 0. 05 ); there were 2 patients died in group A and one in group B ( P ＞ 0.05 ). Conclusion Thromboembolectomy assisted with DSA can be accurate assessment of the arteries embolism position, elevate the success rate in the operation ,reduce the rate of amputation saws.
ABSTRACT
Objective: To study the pharmacologic effects of Compound Black Ant Capsules. Methods: The adjuvant arthritis model of rats (AA rats), delayed hypersensitivity (DTH) model and the pain model induced by acetic acid in mice were used. Results: Compound Black Ant Capsules could significanty inhibit the primary and secondary inflammation of rats induced by the complete Freund's adjuvant, inhibit the ear edema induced by DNCB in mouse and decrease the number of writhes of mouse caused by acetic acid.Conclusion: Compound Black Ant Capsules have the anti inflammatory effect on DTH arthritis and analgesic effect, and inhibit mouse DTH reaction induced by DNCB.
