Early Stent Graft Perforation after Endovascular Repair for Pseudoaneurysm That Was Associated with Clavicle Nonunion.

We report the case of a 62-year-old man who experienced a left axillary artery pseudoaneurysm that was secondary to nonunion of a 30-year-old left midshaft clavicle fracture. He initially underwent endovascular repair using a self-expanding nitinol stent graft, which was perforated at postoperative day 5. Therefore, we performed open repair with concomitant clavicle resection, and no complications were observed during an approximately 6-year follow-up. We recommend performing clavicle resection with vascular repair to prevent recurrence in similar cases.

[Incidental diagnosis of giant cell arteritis during a hybrid surgical approach in a patient with annuloaortic ectasia and an extensive thoracic aortic aneurysm].

We report a case of giant cell arteritis that was incidentally diagnosed during a hybrid( open surgical and endovascular) approach to an extensive thoracic aortic disease. A 78-year-old man was admitted for the evaluation and treatment of annuloaortic ectasia and an extensive thoracic aortic aneurysm. We performed aortic root replacement (Bentall procedure) and total aortic arch replacement using the elephant trunk technique under hypothermic circulatory arrest. Pathological examination of the aneurysmal wall revealed giant cell arteritis. He had no specific symptoms such as headache, jaw claudication, or vision loss. Because no findings except for a slightly elevated erythrocyte sediment rate were suggestive of active vasculitis, he was discharged from hospital without steroid therapy 6 weeks after open surgery. However, 4 weeks later he returned in hemorrhagic shock due to rupture of a residual descending thoracic aortic aneurysm. He underwent emergency endovascular repair but died intraoperatively. In conclusion, early second-stage procedure and postoperative steroid therapy may be useful in a patient with aortic aneurysm in giant cell arteritis undergoing a hybrid procedure.

Chronic obstructive pulmonary disease--an independent risk factor for long-term cardiac and cardiovascular mortality in patients with ischemic heart disease.

BACKGROUND: Limited data are available on long-term mortality and morbidity of patients with chronic obstructive pulmonary disease (COPD) and ischemic heart disease. We examined how COPD affects long-term mortality and morbidity after undergoing percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). METHODS: We analyzed 9877 consecutive patients who underwent their first elective PCI (n=6878) and CABG (n=2999) in 2000-2002 at 30 institutions listed in the CREDO-Kyoto registry. RESULTS: COPD was diagnosed in 240 patients (2.4%). In-hospital mortality (1.3% vs. 1.2%, p=0.972) did not differ between patients with and without COPD. During long-term follow-up (42. 8 month s), 906 patients (9.4%) died, 517 (5.3%) of whom died of cardiovascular death and 376 (3.9%), of cardiac death. At 3 years, the unadjusted survival rate and the rates of freedom from cardiovascular death and cardiac death were 92.1%, 95.3%, and 96.5% in the total population and 82.8%, 91.7%, and 92.1% in patients with COPD respectively. Log-rank test indicated that COPD was associated with higher incidence of all-cause mortality (p<0.0001), cardiovascular death (p=0.0002), and cardiac death (p<0.0001). Multivariate analyses indicated that COPD was an independent predictor of all-cause mortality (hazard ratio 1.36, p=0.0003), cardiovascular death (hazard ratio 1.28, p=0.0407), and cardiac death (hazard ratio 1.48, p=0.003). CONCLUSIONS: COPD is an independent risk factor for long-term cardiac and cardiovascular mortality in patients with ischemic heart disease.
