ABSTRACT
Objective To investigate the clinical effect and value of interventional therapy for post-thrombosis syndrome (PTS).Methods Clinical data of 91 patients with PTS who had received interventional therapy were retrospectively analyzed.The patients were in prone position in surgery.We selected puncture approach of popliteal vein and established a working guidewire channel, and then performed balloon dilatation and stent placement.Results The technical success rate was 98.9% (90/91), with complete recanalization of the stenosis or occluded vessel and restoration of the normal blood flow.There was 1 case of failure to traverse the left common iliac vein segment, but the collateral circulation was rich enough to compensate.The 90 patients were followed up for 6-30 months, with a mean of (18.5±2.3) months.The 6, 12, and 24-month patency rates were 93.3% (84/90), 81.3% (61/75), and 71.4%(20/28), respectively.No stent migration or ulcer recurrence occurred in the 90 patients during the follow-ups.Conclusion For the treatment of PTS, endovascular treatment has high technical success rate.With satisfactory clinical effect, this therapy is safe and effective.
ABSTRACT
Objective To evaluate the efficacy of endovascular interventional minimally invasive techniques in treatment of acute brachial artery injury.Methods A retrospective case series study was designed to analyzed data of 16 cases (11 males and 5 females) sustaining acute brachial artery injury treated from March 2011 to August 2016.Mean age was 47.9 years (range,27-66 years).Left upper extremity vascular injury occurred in 7 cases and right upper extremity vascular injury occurred in 9.There were 13 cases of arterial intima injury and 3 of arterial pseudoaneurysm.All patients underwent endovascular therapy including stent implantation and balloon dilatation.Angiography was used to evaluate the repair of brachial artery and the operation time was recorded.Improvements of distal limb arterial pulse and limb ischemic symptoms were observed,and the patients who were followed up with stent lumen stenosis more than 50％ received endovascular treatment again.Results The procedures was successful in all patients,with operation time of 30-75 minutes (mean,45 minutes).After the insertion of a stent,recovered brachial artery blood flow and disappeared pseudoaneurysm were observed on angiography,without occurrence of stent stenosis or contrast extravasation.Symptoms of local pain and numbness were alleviated,and blood supply of the distal brachial artery was improved after operation.All patients were followed up for 3-36 months(mean,16.7 months).The false aneurysm did not recur.Two cases of stent stenosis more than 50％ had a second balloon dilation procedure and the blood flow returned to normal.Stent patency was found in 14 cases with stent stenosis of less than 50％.During the follow-up period,no ischemic necrosis,displacement of the stent or stent fracture were found.Conclusion For acute brachial artery injury,endovascular management exhibits higher technical success rate and good clinical outcome with a low incidence of complications.
