The patients' demographic characteristics, clinical parameters, endoscopic therapy, adverse events, and outcomes were obtained retrospectively. Technical success was defined as effective restoration of oesophageal patency. Swallowing success was defined as either percutaneous endoscopic gastrostomy(PEG)-tube independency and/or relevant improvement of oral food intake, as assessed by the functional oral intake scale(FOIS)(≥ level 3).RESULTS: The cohort consisted of six patients [five males; mean age 71 years(range, 54-74)]. All but one patient had undergone radiotherapy for head and neck or oesophageal cancer. Technical success was achieved in five out of six patients. After discharge, repeated dilations were performed in all five patients. During follow-up(median 27 mo, range, 2-115), three patients remained PEG-tube dependent. Three of four patients achieved relevant improvement of swallowing(two patients: FOIS 6, one patient: FOIS 7). One patient developed mediastinal emphysema following CARD, without a need for surgery.CONCLUSION: The CARD technique is safe and a viable alternative to high-risk blind antegrade dilation in patients with complete proximal oesophageal obstruction. Although only half of the patients remained PEG-tube independent, the majority improved their ability to swallow.展开更多

However, when treating the blunt CTO with a large side branch proximal to the occlusion, the side branch might be occluded after stent implantation if the retrograde guidewire passed the occluded segment through the subintimal space and re-entered into the true lumen at the opposite side of the side branch.[4] We reported a useful method to solve the above issue which utilizes intravascular ultrasound (IVUS) to guide “extended” reverse controlled antegrade and retrograde subintimal tracking (CART) technique with a cutting balloon.展开更多

We report, two cases of a fracture of the femur at the interlocking screw site in the subtrochanteric area after retrograde femoral nailing of a femoral shaft fracture. Only a few reports in the existing literature have described these fractures. Two young men after sustaining a fall presented to us with pain, swelling and deformity in the upper thigh region. On enquiring, examining and radiographing them, peri-implant fractures of subtrochanteric nature through the distal interlocking screws were revealed in both patients who also had histories of previous falls for which retrograde intramedullary nailing was performed for their respective femora. Both patients were managed with similar surgical routines including removal of the existing hardware, open reduction and ace cephallomedullary antegrade nailing. The second case did show evidence of delayed healing and was additionally stabilized with cerclage wires. Both patients had uneventful postoperative outcomes and union was evident at the end of 6 mo postoperatively with a good range of motion at the hip and knee. Our report suggests that though seldom reported, peri-implant fractures around the subtrochanteric region can occur and pose a challenge to the treating orthopaedic surgeon. We suggest these be managed, after initial stabilization and resuscitation, by implant removal, open reduction and interlocking intramedullary antegrade nailing. Good results and progression to union can be expected in these patients by adhering to basic principles of osteosynthesis.展开更多

In retrograde TAAD (r-TAAD) cases, some authors reported the efficacy of thoracic endovascular aortic repair (TEVAR). However, only a few reports chose TEVAR for the treatment of r-TAAD resulting in cardiac arrest before hospital arrival. We report a case of r-TAAD presenting with cardiac arrest before hospital arrival not indicated for surgery but TEVAR as treatment. <strong>Case: </strong>A 65-year-old woman with a history of Marfan syndrome presented to the emergency department after a CPA. Sequential return of spontaneous circulation was achieved 27 min after CPA. Contrast-enhanced computed tomography showed retrograde r-TAAD with an entry tear to the false lumen in the thoracic descending aorta. Therefore, thoracic endovascular aortic repair (TEVAR) was performed with r-TAAD. Afterward, the clinical course was stabilized. This patient suggests that TEVAR is an effective option for the treatment of patients with hemodynamically unstable r-TAAD, even after CPA. <strong>Conclusion:</strong> TEVAR can lead to a successful recovery from cardiac arrest due to r-TAAD.展开更多
