External Iliac Artery Endofibrosis in a Female Cyclist: A Case Report.

External iliac artery endofibrosis is a rare disease described mainly in male endurance athletes. It presents as claudication of the lower limb during near-maximum effort. The patients lack the usual risk factors for atherosclerosis, which makes diagnosis challenging. We present a case of external iliac artery endofibrosis in a female competitive cyclist. The initial surgical management was complicated by early recurrence due to intimal hyperplasia. After secondary drug-eluting balloon angioplasty, the patient was able to resume competition. As such, it is important to maintain a high index of suspicion when evaluating a patient presenting with claudication symptoms in this setting. Primary treatment is surgical, and in cases of early recurrence angioplasty may be indicated. Most patients can return to full activity after healing is complete.

Risk factors of postcardiotomy ventricular dysfunction in moderate-to-high risk patients undergoing open-heart surgery.

INTRODUCTION: Ventricular dysfunction requiring inotropic support frequently occurs after cardiac surgery, and the associated low cardiac output syndrome largely contributes to postoperative death. We aimed to study the incidence and potential risk factors of postcardiotomy ventricular dysfunction (PCVD) in moderate-to-high risk patients scheduled for open-heart surgery. METHODS: Over a 5-year period, we prospectively enrolled 295 consecutive patients undergoing valve replacement for severe aortic stenosis or coronary artery bypass surgery who presented with Bernstein-Parsonnet scores >7. The primary outcome was the occurrence of PCVD as defined by the need for sustained inotropic drug support and by transesophageal echography. The secondary outcomes included in-hospital mortality and the incidence of any major adverse events as well as Intensive Care Unit (ICU) and hospital length of stay. RESULTS: The incidence of PCVD was 28.4%. Patients with PCVD experienced higher in-hospital mortality (12.6% vs. 0.6% in patients without PCVD) with a higher incidence of cardiopulmonary and renal complications as well as a prolonged stay in ICU (median + 2 days). Myocardial infarct occurred more frequently in patients with PCVD than in those without PCVD (19 [30.2%] vs. 12 [7.6%]). By logistic regression analysis, we identified four independent predictors of PCVD: left ventricular ejection fraction <40% (odds ratio [OR] = 6.36; 95% confidence interval [CI], 2.59-15.60), age older than 75 years (OR = 3.35; 95% CI, 1.64-6.81), prolonged aortic clamping time (OR = 3.72; 95% CI, 1.66-8.36), and perioperative bleeding (OR = 2.33; 95% CI, 1.01-5.41). The infusion of glucose-insulin-potassium was associated with lower risk of PCVD (OR = 0.14; 95% CI, 0.06-0.33). CONCLUSIONS: This cohort study indicates that age, preoperative ventricular function, myocardial ischemic time, and perioperative bleeding are predictors of PCVD which is associated with poor clinical outcome.

Rescue of a Failing Endovascular Infrarenal Aortic Repair Using an Off-The-Shelf Branched Endograft.

BACKGROUND: Proximal aortic dilation following open and endovascular aortic repair (EVAR) is a well-known phenomenon. If severe enough, it may lead to late onset of type Ia endoleak that jeopardizes the proximal seal. METHODS: We report the case of a patient previously treated by EVAR for an infrarenal aneurysm who developed a type Ia endoleak after proximal aortic dilation. His aneurysms enlarged to 10 cm mandating a rapid repair without the delay for a custom-made device. RESULTS: We successfully used the off-the-shelf thoracic t-Branch graft (Cook, Bloomington, IN) with its 4 branches to treat the dilated aorta and seal the endoleak. CONCLUSION: The off-the-shelf t-Branch is a useful option in patient with previous EVAR presenting with proximal aortic dilation and endoleak who cannot wait for a custom-made device.
