In patients undergoing major orthopedic surgery, data of deep venous thrombosis (DVT) and pulmonary embolism (PE) are lacking as studied by computed tomographic (CT) pulmonary angiography and indirect CT venography (CTPA-CTV). A prospective observational study was performed for 363 Korean patients undergoing major orthopedic surgery to determine the incidence of venous thromboembolism (VTE), especially proximal DVT and PE. The incidence of VTE was 16.3% (n=59). Of them, 8 patients (2.2%) were symptomatic. The rate of VTE was the highest in patients who underwent total knee replacement (40.4%), followed by hip fracture surgery (16.4%), and total hip replacement (8.7%; P<0.001). The incidence of PE was 6.6% (n=24). Of them, 4 patients (1.1%) were symptomatic. Forty-one patients (11.3%) were in the proximal DVT or PE group. Based on multivariate analysis, total knee replacement and age > or =65 yr were significant risk factors for proximal DVT or PE in patients undergoing major orthopedic surgery (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.1-5.1; P=0.025; and OR, 2.1; 95% CI, 1.0-4.4; P=0.046, respectively). Taken together, the overall incidence of PE was 6.6% and rate of symptomatic PE rate was 1.1%. Knee joint replacement and age > or =65 yr were significant risk factors for proximal DVT or PE.

The bowel transplantation team at the Catholic Medical Center, Korea, on April 9 2004, accomplished a case of isolated small bowel transplantation (SBT) in a 57 year-old female with short bowel syndrome. The primary surgery was a jejunocolostomy due to mesenteric vein thrombosis, while maintaining 30 cm of the jejunum and colon distal to the splenic flexure. Her renal function was partially unbalanced. During more than 2 years of home TPN, the superior vena cava (VC) and subclavian veins had become occluded, but the inferior VC line remained. SBT was planned due to the repeated life-threatening infections of the last central line. One hundred and fifty centimeter of the distal ileum of the 27 year-old living-related donor, the patient's daughter, was harvested. The graft mesenteric artery and vein were anastomosed to the recipient's inferior mesenteric vessels. A proximal end- to-end jejuno-ileostomy and a distal end-to-side ileo-colostomy of the graft were made, creating a Bishop-Koop enterostomy for graft surveillance. A tube jejunostomy, via a gastrostomy, was established for early feeding and simultaneous gastric drainage. Induction with Daclizumab and immunosuppression consisted of tacrolimus and methylprednisolone, given intravenously, and then mycophenolate mofetil (MMF), enterally from day 3. The patient was discharged on day 42. A CMV infection on day 83 was successfully treated with 3 weeks of gancyclovir therapy. She has been nutritionally independent, with complete oral feeding, and free of rejection until day 170 after the transplantation.

A 58-year-old female patient, diagnosed with adenocarcinoma of the lung, underwent percutaneous vertebroplasty at the L4 vertebral body due to painful spinal metastases. Because of deep venous thrombosis of the left femoral and iliac veins, an inferior vena cava filter had been placed before vertebroplasty. Bone cement migrated into the venous bloodstream and then was being trapped within the previously placed filter. This case illustrates that caval filter could capture the bone cement and prevent it from migrating to the pulmonary circulation.

OBJECTIVEDue to its minimal-invasive approach, endovascular procedure had replaced surgery in treating Budd-Chiari syndrome (BCS). The interventional therapy was a safe and effective treatment in adults with BCS and the cure rate was high. However Budd-Chiari syndrome in children and adolescents is rare. Published literature on interventional procedure for Budd-Chiari syndrome in children and adolescents is scarce. The aim of the study was to present results of percutaneous transluminal angioplasty (PTA) and stents placement in children and adolescents with BCS and to evaluate the efficacy and safety in these patients of this approach.

METHODTwenty-five patients [16 boys and 9 girls; average age of (14.5 ± 3.4) years old; age ranged from 5 to 17 years] with Budd-Chiari syndrome who were hospitalized from December 1990 to August 2012 were presented. All of them were diagnosed by color Doppler ultrasound scan while 12 of them had magnetic resonance venography (MRV) scan. All of the patients had undergone angiographic examination. Four cases with membranous obstruction of the inferior vena cava (IVC) were treated with PTA. One case with segmental block of IVC was treated with PTA and stent placement. Five cases with membranous obstruction of IVC and hepatic vein (/and accessory hepatic vein) were treated with PTA. Among 8 cases with membranous obstruction of hepatic veins, 6 cases were treated with PTA and the others with PTA and stent placement. Among 4 cases with blocks of 3 hepatic veins (HVs), one was treated with PTA, one with PTA plus catheter thrombolysis plus PTA, one with PTA and stent placement and the other one was unsuccessful. Three cases with obstruction of HV and accessory HV (AHV) were treated with PTA. Totally, 24 patients were treated with interventional approach and followed up.

RESULTThe procedure was successful in 24 patients. The involved veins (hepatic veins or IVC) were patented after interventional procedure. The pressure of hepatic vein was (42.1 ± 4.2) cm H2O (37-50 cm H2O) (1 cm H2O = 0.098 kPa) before the interventional therapy, while it was (17.3 ± 3.3) cm H2O (14-26 cm H2O) after it. The pressure of IVC was (30.6 ± 2.9) cm H2O (26-36 cm H2O) before the interventional therapy, while it was (18.8 ± 4.2) cm H2O (15-26 cm H2O) after it. The symptoms and signs vanished instantly after interventional procedure. There were no procedure-related complications. The rate of overall initial cure was 96%. The patients were followed up for a mean of 25.8 months (range 6 months to 8 years). Seven cases developed restenosis after first procedure. Five of them were treated with PTA, one with PTA plus catheter thrombolysis plus PTA, one with PTA and stent placement. All of the involved veins were patented again. Clinical symptoms were relieved. There were no procedure-related complications as well.

CONCLUSIONThe interventional procedure in children and adolescents with BCS is the same as in adults. Radiological therapeutic intervention is efficacious and safe in children and adolescents with BCS.
