Hybrid Endovascular Repair of Thoracic Aortic Aneurysm in a Patient with Behçet's Disease Following Right to Left Carotid-carotid Bypass Grafting
Endovascular repair of inflammatory aortic aneurysms has been reported as an alternative to open surgical treatment. In selective cases, adjunctive bypass surgery may be required to provide an adequate landing zone. We report a case of endovascular repair of an inflammatory aortic aneurysm in a patient with Behçet's disease using a carotid-carotid bypass graft to provide an adequate landing zone. A 45-yr-old man with a voice change was referred to our hospital with the diagnosis of saccular aneurysm of the distal aortic arch resulting from vasculitis. Computed tomography showed a thoracic aortic aneurysm with thrombosis. Right to left carotid-carotid bypass grafting was performed. After 8 days, the patient underwent an endovascular stent graft placement distal to the origin of the innominate artery. The patient was discharged with medication and without postoperative complications after 5 days. Hybrid endovascular treatment may be suitable a complementary modality for repairing inflammatory aortic aneurysms
Progressing takayasu arteritis successfully treated by common carotid-internal carotid crossover bypass grafting: technical case report.
OBJECTIVE: This report describes a unique case of Takayasu arteritis with occlusion of the left common carotid artery (CCA) and the right internal carotid artery (ICA), which was successfully treated by right CCA-left ICA crossover bypass grafting using the saphenous vein. The histological findings of the original occluded prosthetic graft are also described. CLINICAL PRESENTATION: A 63-year-old woman with a history of Takayasu arteritis was admitted to our hospital with a history of progressive dizziness, frequent syncopal attacks, and repetitive blurred vision in the left eye. She had undergone repeat transthoracic bypass surgeries, including grafting with the use of a Gore-Tex (W.L. Gore & Associates, Inc., Flagstaff, AZ) prosthesis between the left external ilioaxillary bypass and the left CCA. However, cerebral angiography demonstrated total occlusion of the left CCA, the right ICA, and the bilateral subclavian arteries. On admission, I-iodoamphetamine single-photon emission computed tomography showed a decreased cerebrovascular reactivity to acetazolamide in the bilateral cerebral hemispheres. Moreover, cerebral angiography revealed an occlusion of the Gore-Tex graft, whereas the left ICA was opacified through the retrograde filling in the left external carotid artery. INTERVENTION: Crossover bypass grafting was performed using the saphenous vein between the right CCA and the left ICA. The Gore-Tex graft was partially removed, and myointimal hypertrophy with an inflammatory response around the wall was found histologically. The postoperative course was uneventful. A normalized cerebrovascular reserve in both cerebral hemispheres was demonstrated on I-iodoamphetamine single-photon emission computed tomography. CONCLUSION: Although it is not frequently indicated, crossover bypass grafting using the saphenous vein between bilateral carotid arteries is considered to be a feasible alternative procedure in patients with Takayasu arteritis.This is a non-final version of an article published in final form in Neurosurgery, 65(5), pp.1178-1179; 2008

Long-Term Prognosis of Diabetic Patients With Critical Limb Ischemia: A population-based cohort study
OBJECTIVE\u2014 To evaluate the long-term prognosis of critical limb ischemia (CLI) in diabetic
patients.
RESEARCH DESIGN AND METHODS\u2014 A total of 564 consecutive diabetic patients
were hospitalized for CLI from January 1999 to December 2003; 554 were followed until
December 2007.
RESULTS\u2014 The mean follow-up was 5.93 1.28 years. Peripheral angioplasty (PTA) was
performed in 420 (74.5%) and bypass graft (BPG) in 117 (20.6%) patients. Neither PTA nor BPG
were possible in 27 (4.9%) patients. Major amputations were performed in 74 (13.4%) patients:
34 (8.2%) in PTA, 24 (21.1%) in BPG, and 16 (59.2%) in a group that received no revascularization.
Restenosis occurred in 94 patients, bypass failures in 36 patients, and recurrent ulcers in
71 patients. CLI was observed in the contralateral limb of 225 (39.9%) patients; of these, 15
(6.7%) required major amputations (rate in contralateral compared with initial limb, P 0.007).
At total of 276 (49.82%) patients died. The Cox model showed significant hazard ratios (HRs) for
mortality with age (1.05 for 1 year [95% CI 1.03\u20131.07]), unfeasible revascularization (3.06
[1.40\u20136.70]), dialysis (3.00 [1.63\u20135.53]), cardiac disease history (1.37 [1.05\u20131.79]), and impaired
ejection fraction (1.08 for 1% point [1.05\u20131.09]).
CONCLUSIONS\u2014 Diabetic patients with CLI have high risks of amputation and death. In
a dedicated diabetic foot center, the major amputation, ulcer recurrence, and major contralateral
limb amputation rates were low. Coronary artery disease (CAD) is the leading cause of death, and
in patients with CAD history the impaired ejection fraction is the major independent prognostic
factor
Themes that Determine Quality of Life in Patients with Peripheral Arterial Disease: A Systematic Review
© 2018 Springer International Publishing AG, part of Springer Nature Objectives: The aim of this study was to identify domains that determine quality of life in patients with peripheral arterial disease and find the patient-reported outcome measures that can examine the identified themes. Methods: A systematic review of all the main six databases was undertaken to identify primary qualitative studies reporting on the health and/or quality of life of patients with peripheral arterial disease. The quality of studies was assessed using the Critical Appraisal Skills Program criteria. Findings from the included studies were analysed using framework analysis methodology. The identified themes were mapped against the items/domains of validated patient-reported outcome measures used in patients with peripheral arterial disease. Results: The systematic review identified eight papers that fulfilled the inclusion criteria. The included papers reported the views of 186 patients with peripheral arterial disease including patients with intermittent claudication, critical ischaemia and amputation secondary to peripheral arterial disease. The overall quality of the included studies was good based on Critical Appraisal Skills Program criteria. Framework analysis identified 35 themes that were divided into six main groups: symptoms, impact on physical functioning, impact on social functioning, psychological impact, financial impact and process of care. The best-fit generic and disease-specific patient-reported outcome measures were the Nottingham Health Profile and the Vascular Quality of Life Questionnaire, respectively. None of the patient-reported outcome measures covered all the themes important to patients with peripheral arterial disease. Discussion: The findings from the review identified the important domains that affect patients living with peripheral arterial disease. None of the current generic and disease-specific patient-reported outcome measures provide a comprehensive measure for all themes that impact the daily living of patients with peripheral arterial disease
