ABSTRACT
Aortoesophageal fistula is a rare but lethal complication after thoracic endovascular repair for thoracic aortic diseases. Extensive treatment is reserved for patients fit for surgery. Various technical approaches have been described; however, mortality rates are still high. Herein, we report a case of a 76-year-old woman with aortoesophageal fistula treated by a three-step treatment approach, with close collaboration between cardiothoracic and general surgery specialists. The patient required tracheostomy after the first procedure, but this was closed at 15 days. She subsequently recovered and is doing well at 3 months after surgery. Staged treatment aims to shorten operative times, to reduce the risk of anesthesia complications, and to provide the patients the time to recover after each procedure.

BACKGROUND: Peripheral artery disease (PAD) affecting the femoropopliteal artery is treated by endovascular interventions [2, 5, 13] increasingly. Aim of the study was to evaluate mid-term efficacy and patency of long stents in the superficial femoral and popliteal artery. PATIENTS AND METHODS: Between September 2006 and September 2007 103 patients received 128 stents for endovascular treatment of femoropopliteal vascular stenosis or occlusion. Clinical and hemodynamic parameters were collected. Risk factors, popliteal involvement and TASC classification, were documented and evaluated. RESULTS: Immediate outcome was satisfactory with a technical success rate of 100 %. After a mean follow-up period of 21 months, primary patency was 83.6 %. Potential risk factor analysis for restenosis and fracture demonstrated hypertension to have borderline significance (P = 0.06). In normotensive patients no restenosis occurred. Further pre-conditions, e.g. smoking, metabolic syndrome, age, gender and previous intervention did not show any influence on restenosis or stent fracture. TASC C and D lesion had similar patency rates compared to TASC A and B lesions. Most of the restenoses (13 out of 16) were observed within the first six months of follow-up. Six stent fracture were observed (4.7 %). CONCLUSIONS: Long stents had convincing results after endovascular treatment of the femoropopliteal PAD. The used stent was an efficacious endovascular tool for long athersclerotic lesions in the superficial femoral and popliteal artery. Fracture rate was low with an incidence of 4.7 %. Most restenoses occurred within the first six months so that careful follow-up would be necessary.

BACKGROUND: This study evaluated the therapeutic value of endovascular techniques in patients with buttock claudication caused by stenosis or occlusion of the internal iliac artery. METHODS: The records of patients with buttock claudication who had undergone endovascular treatment for internal iliac artery stenosis or occlusion were analyzed retrospectively, and any associated arterial lesions, morbidity, restenosis, or recurrent buttock claudication was noted. Outcomes were compared with published reports. Iliac artery duplex scans and aortoiliac angiography were performed to detect and confirm the internal iliac artery obstructive disease. The iliac duplex scanning surveillance protocol was set at 3, 6, and 12 months and yearly thereafter to detect eventual restenosis or occlusion. RESULTS: Between September 2006 and September 2008, 21 consecutive patients (19 men; mean age, 67 years) with 22 cases of buttock claudication (1 bilateral localization) underwent percutaneous transluminal angioplasty alone (14 cases) or additional stent placement in case of elastic recoil (8 cases). Buttock claudication was associated with impotence, thigh claudication, or calf claudication in seven patients. The endovascular approach was successful in all patients, without morbidity or mortality. During a mean follow-up of 14.7 +/- 5.7 months, 50% restenosis occurred in one 80-year-old patient. The patient had a pain-free walking distance of 110 meters and was treated conservatively. CONCLUSIONS: To our knowledge, the present study is the largest published report concerning endoluminal treatment of buttock claudication due to internal iliac artery obstructive disease. The midterm results are very encouraging and underscore the value of stent-supported angioplasty as first-line treatment. The procedure can be repeated should significant restenosis occur and does not compromise the option of surgical repair of the lesions.
