  • Percutaneous endovascular interventional treatment for bilateral iliofemoral venous thrombosis: clinical results of 18 cases

    Objective To investigate the clinical effect of percutaneous endovascular interventional treatment for bilateral iliofemoral venous thrombosis. Methods From November 2012 to February 2016, the clinical data of 18 patients with bilateral iliofemoral venous thrombosis were retrospectively analyzed. All patients including 7 males and 11 females, aged from 51 to 86 years with an average of (66.2±7.8) years old. All patients underwent interventional treatment, and mechanical aspiration thrombectomy was performed under the protection of inferior vena cava filter at the acute or subacute phase; those whose venography showed iliac vein stenosis received balloon dilatation and self-expandable stents immediately. Iliac vein stenosis received balloon dilatation and self-expandable stents immediately at the chronic phase. Results The treatment was successful in all patients. The circumference difference of thigh and calf was (7.3±2.1) and (4.6±2.7) cm respectively before and after treatment. Thirteen patients with stenosis or occlusion of the iliac vein were treated with adjunctive balloon dilatation and stent placement, and 20 self-expandable stents were inserted successfully. All the patients were followed up for 12–34 months with an average of (21.5±7.3) months; stenosis or occlusion of the stent were seen in 1 patient after 9 months; post thrombotic syndrome was observed in 1 patient after 12 months. The 12-month primary patency rate and secondary patency rate was 88.9% (16/18) and 100.0% (18/18), respectively. Conclusion Endovascular interventional therapy of bilateral iliofemoral venous thrombosis is a safe and effective method.

  • Experience of endovascular therapy for spontaneous isolated superior mesenteric artery dissection

    Objective To evaluate the clinical efficacy and safety of endovascular therapy for spontaneous isolated superior mesenteric artery dissection (SISMAD). Methods The clinical data of 17 patients with SISMAD, who were treated at author's hospital during the period from March 2009 to May 2016, were retrospectively analyzed. According to the Sakamoto angiographic classification, patients were divided into typeⅠ (n=3), typeⅡ (n=5), and type Ⅲ (n=9). Three patients with type Ⅰ were treated with conservative treatment first, and then 2 were treated with endovascular therapy as the poor reaction. The other patients were treated with endovascular treatment right a way. Results Conservative treatment was success in 1 case, 16 patients were treated with endovascular treatment, the technical success rate was 100%, one stent was used in 11 patients and two stents were used in 5 patients, and the blood in the true lumen of superior mesenteric artery (SMA) restored, no major complications occurred. Seventeen patients were followed-up for 3-36 months (mean of 19 months) and the followed-up rate was 100%, no abdominal pain occurred in 17 cases, CTA showed that no dissecting aneurysm was observed and the stents were patent of SMA. Conclusion Interventional therapy is a safe and effective method for SISMAD.

  • Application of vascular interventional technique in arterial injuries of damage control surgery

    ObjectiveTo investigate the effect of vascular interventional technique in arterial injuries of damage control surgery.MethodsA retrospective review was made on clinical data of 31 arterial injuries cases who received damage control surgery from March 2011 to June 2018. All cases underwent endovascular therapy for arterial injuries in No. 960 Hospital of Chinese People’s Liberation Army, and then the definitive operation was operated as soon as the vital signs became stable.ResultsThe surgery was successful in all patients, and the operation time was 43–100 min (average of 57 min), the intraoperative blood loss was 50–200 mL (average of 80 mL). Bleeding was successful controlled in 11 cases with covered stents, 9 cases with multiple overlapping bare stents, and 11 cases with spring coil, all cases with shock were improved immediately. There were no perioperative mortality or procedure-related complication occurred. All cases were discharged from hospital smoothly after two-phase surgery. All the patients were followed up for 6 to 24 months [(17±5) months]. Two patients with covered stent lumen stenosis less than 50% as showed by angiography, and no secondary treatment was required. In addition, blood flow patency was kept in the rest of artery, no bleeding occurred in injured artery. During the follow-up period, the collateral vessels of 9 patients treated with multi-layerbare stent overlapping technique were unobstructed. Stent migration, fracture or leakage was not found during the follow-up period. Patients recovered well after definitive surgery, they had good fracture healing with a disability rate of 0.ConclusionRational application of vascular interventional technique in damage control surgery is a safe and effective treatment method for arterial injuries combined with other traumas.

  • Therapy experience of multiple interventional technologies for visceral artery aneurysms in 32 cases

    ObjectiveTo investigate treatment methods and effect of endovascular interventional therapy for visceral artery aneurysms.MethodsThe clinical data of 32 patients with visceral artery aneurysms, who were treated in the No. 960 Hospital of PLA from February 2011 to April 2018, were retrospectively analyzed. It was proveded by the CT or digital subtraction angiography before the interventional therapy. The implantation of covered stent, coil embolization together with stent implantation, double stents placement or pure coil embolization were performed. The postoperative antithrombotic therapy was adopted in the patients accepted the stent implantation. The CT angiography was performed on the month of 1, 6, 12, 24 or the patient was uncomfortable after the treatment to evaluate the obstruction condition of the aneurysms, stent blood flow, and branches arteries, etc..ResultsThe success rate of the endovascular interventional therapy was 100%. In the 11 patients underwent the implantation of covered stent, the postoperative angiography showed that the stent lumen was patent and the aneurysm was not visualized. In the 9 patients underwent the coil embolization together with stent implantation and 3 patients underwent the double stents placement, the postoperative angiography results of the aneurysm showed that it was faintly visualized and the branch arteries were not involved. In the 9 patients underwent the pure coil embolization, the postoperative angiography showed that the aneurysm was not visualized. No perioperative mortality or procedure related complications occurred. No case was lost during the follow-up of a median period of 25.5 (6–48) months. During the follow-up, one patient developed the mild abdominal pain in one month, which disappeared after the symptomatic medication management. Except for 1 patient developed the mild stent stenosis (<30%) on the 12th month after the procedure, the stent and the branch arteries of the other patients were completely patent, and no aneurysms recurred.ConclusionFor treatment of visceral artery aneurysms, endovascular interventional therapy is safe and effective and shows an excellent short-term and mid-term effects.
