RESUMEN
A 38-year-old man presented with embolic occlusion of the brachial artery. As per his computed tomography results, a pedunculated mass in the proximal ascending aorta was detected. Since discrimination between a thrombus and a tumor was deemed difficult, the patient underwent replacement of the ascending aorta. Histopathology revealed the mass to be a thrombus. The diagnosis of antiphospholipid syndrome was then confirmed postoperatively. Six months post-surgery, a new thrombus was detected in the vascular prosthesis. The thrombus resolved after treatment with edoxaban and aspirin. To the best of our knowledge, this is the first report on graft thrombosis in antiphospholipid syndrome, highlighting the importance of seamless anticoagulation therapy.
RESUMEN
A popliteal artery aneurysm is one of the most common peripheral arterial aneurysms. These aneurysms can cause distal embolization and thrombosis, leading to limb loss. However, their rupture is unusual. Here we report a case in which a popliteal aneurysm with chronic occlusion at its outflow artery developed a nonfatal, painful rupture. We performed only coil embolization of the proximal artery, and the aneurysm was successfully excluded. After the procedure, collateral circulation was maintained. No ischemic symptoms such as intermittent claudication or pain at rest were observed. This approach may be useful in treating similar cases.
RESUMEN
OBJECTIVES: The aim of this study was to evaluate the deployment accuracy of a new 'through-and-through bowing technique' that involves the deployment of the stent graft with total arch debranching via median sternotomy. METHODS: The migration distance, patients' demographic characteristics, operative values and the postoperative complications were examined retrospectively. From November 2012 to February 2013, 5 patients with an aortic arch aneurysm underwent total debranching and antegrade thoracic endovascular aneurysm repair (TEVAR) (control group). Fifteen patients underwent placement using the 'through-and-through bowing technique' (bowing group) from March to November 2013. The device was deployed as follows. A stiff guide wire was passed through the debranching prosthesis via the femoral artery. By pushing the bilateral ends of the wire against the aortic arch, the device was located along the greater curvature and bent like a bow. The migration distance, defined as the distance between the pre- and post-deployment positions of the distal end of the stent graft, was measured using fluoroscopic images. RESULTS: There were no significant differences with respect to the patients' demographics or the operative variables between the two groups. The mean migration distance in the control group (9.4 ± 8.7 mm) was significantly longer than that in the bowing group (1.3 ± 1.5 mm). Although one major stroke occurred in the bowing group, there was no operative mortality in either group. CONCLUSIONS: The present paper demonstrated the precise positioning of a GORE TAG deployment using a 'through-and-through bowing technique' with total arch debranching.

PURPOSE: We herein review the long-term results of our series of critical ischemic limbs caused by Buerger's disease. METHODS: A retrospective review of 103 patients with critical limb ischemia who were diagnosed with Buerger's disease by Shionoya's criteria between 1980 and 2010. RESULTS: The age of onset was 38.0 ± 9.7 years (mean ± SD). The median follow-up was 97 months. Thirty-three patients had pain at rest, and 65 patients presented with ischemic ulcers in their toes and/or fingers. Gangrene was present in five patients. Sixteen patients achieved remission with medical therapy and smoking cessation. Sixty-six patients underwent sympathectomy. Bypass to the crural arteries was performed in 23 limbs, with assisted primary patency rates of 67.0 and 45.6 % at five and 10 years. Graft failure caused major amputation in two out of 10 smokers, but no limbs were lost among the 12 ex-smokers. Therapeutic angiogenesis using cell transplantation led to improvement in three ex-smokers; however, amputation was unavoidable in the one smoker who was treated. The limb salvage rate at 20 years was 90 % in ex-smokers and 69 % in smokers, which was not significantly different. CONCLUSIONS: This study demonstrated no significant difference in the limb salvage rate between ex-smokers and smokers. Our results do not support any advantageous effect of smoking cessation on the long-term remission in patients with Buerger's disease.

We report a case of late type III B endoleak from a fabric tear in the main body of a Zenith bifurcated stent-graft approximately 19 months after implantation. A follow-up computed tomography (CT) scan showed gradual growth in the size of the aneurysm, but no apparent endoleak was recognized. However, the CT scan had demonstrated a mosaic pattern in the aneurysm sac, which could indicate an endoleak from a fabric tear. The defect was repaired by implantation of body extensions, but the patient died 5 h after the procedure.

We present a case of a left subclavian artery aneurysm in a 48-year-old man with Marfan syndrome. Aneurysms of the subclavian artery are rare in patients with Marfan syndrome. Resection of the aneurysm and interposition with a synthetic graft were performed through a supra- and infraclavicular incision, without resecting the clavicle. Histological findings were compatible with Marfan syndrome. In patients with Marfan syndrome, regular follow-up is important because of the occurrence of peripheral aneurysms other than the aorta.

PURPOSE: We conducted this study to compare the cost of open surgical repair (OR) with that of endovascular aneurysm repair (EVAR) of an abdominal aortic aneurysm (AAA). METHODS: Between January 2007 and November 2008, 70 patients underwent open repair and 57 patients underwent EVAR. We evaluated the total cost, including that of the Diagnosis Procedure Combination (DPC), that of the surgical procedure, that of materials such as grafts and guide wires, and that of the anesthesia. RESULTS: The mean costs for OR versus EVAR were as follows: DPC, ¥632,370 versus ¥490,050, respectively, which was significant; anesthesia, ¥123,540 versus ¥86,220, respectively (P < 0.05); and materials, ¥257,770 versus ¥2,113,280, respectively (P < 0.05). Thus, the mean total cost was ¥1,825,830 versus ¥3,159,270 for open repair and EVAR, respectively (P < 0.05). CONCLUSIONS: New technologies should not only be clinically effective, but also cost effective. EVAR is less invasive clinically, but the cost of endovascular prostheses and other materials remains high.
