OBJECTIVES The Hardman index, which has five variables, has been recommended as a predictor of outcome after open repair of ruptured abdominal aortic aneurysms (RAAAs). It has been reported that the presence of three or more variables is uniformly fatal. The aim of this study was to test the same model in an independent series of RAAA patients undergoing endovascular repair. METHODS A consecutive series of 41 patients undergoing endovascular repair for RAAA during an 8-year period was analyzed retrospectively. Thirty-day mortality and patient variables, including the five Hardman risk factors of age >76 years, serum creatinine >190 micromol/L, hemoglobin <9 g/dL, loss of consciousness, and electrocardiographic (ECG) evidence of ischemia, were recorded. The Hardman index and a revised version of the index with four variables (without ECG ischemia) were calculated and related to clinical outcome. RESULTS Operative mortality was 41% (17 of 41). On univariate analysis, only age >76 years (P = .01) and the use of local anesthesia (P < .0001) were statistically significant. Loss of consciousness (P = .05) showed a trend toward a higher mortality, albeit not statistically significant. On multivariate analysis, the use of local anesthesia was the only significant predictor of survival (odds ratio [OR], 0.03; 95% confidence interval [CI], 0.003-0.25, P = .001). Again, loss of consciousness showed an association with a higher chance of dying but did not achieve statistical significance (OR, 6.30; 95% CI, 0.93-42.51, P = .059). The original and revised versions of the Hardman index were both significantly associated with death (P = .02 and P = .001, chi(2) test for trend). The cumulative effect of 0, 1, 2, and >/=3 risk factors on mortality was 0%, 27%, 36%, and 71% for the original index, and 12.5%, 21%, 60%, and 78% for the revised version, respectively. Four and two patients with a score of >/=3 in each version of the index survived endovascular repair. CONCLUSIONS The Hardman index, with or without incorporating ECG ischemia, seems to be a simple and useful predictive tool in patients undergoing endovascular repair of RAAA, with the mortality rate increasing along with the Hardman score. However, the index cannot be used to accurately identify patients with no chance of survival after endovascular repair.

Introduction. Coexistence of carcinoid tumor inside a mature cystic teratoma is an extremely rare phenomenon, especially in young women. We present the case of a 28-year-old woman diagnosed with a right ovarian carcinoid and treated uneventfully with conservative surgical approach. Case Report. A 28-year-old woman, gravid 0, parity 0, presented to our department for her annual gynecological examination and Pap smear test. During her examination, a mobile cystic mass was detected in the right lower abdomen. Ultrasound indicated a right ovarian mass 10.5 × 6.3 cm, confirmed by CT scan. Further investigation revealed AFP levels (1539 ng/mL). The ovarian mass was excised by laparoscopy, leaving intact the remaining right ovary. Frozen sections showed a mature cystic teratoma. However, paraffin sections revealed the presence of a small carcinoid within the teratomas gastric-type mucosa. The patient was set to a close followup. Nine months postoperatively, ultrasound pelvis imaging and CT scan of the abdomen as well as serum tumor markers have shown no evidence of recurrence disease. Conclusion. Despite the weak evidence, fertility spare surgical approach for women wanting to preserve their genital tract might be a reasonable option.

Background: Primary aldosteronism (PA) is a syndrome which includes a group of clinical entities in which aldosterone production is inappropriately high and nonsupressible by sodium loading. The most frequent causes of PA are adrenal adenoma and unilateral or bilateral primary hyperplasia. Methods: We report a case of a 55-year-old man with a 10-year history of hypertension in whom functional hormonal studies were indicative of PA. Because adrenal venus sampling was not available at our hospital, the investigation was conducted with a computed tomography (CT) scan and a scan with 131-iodocholesterol (NP-59) which both revealed a left adrenal adenoma. Results: The tumor was excised laparoscopically without any complications and the histological findings confirmed the diagnosis of an aldosterone-producing adenoma. Blood pressure remained normal despite the discontinuation of antihypertensive drugs, further supporting that the adrenal tumor was indeed the cause of high blood pressure. Unfortunately, blood pressure began to rise again 2 months later, and laboratory findings indicated the presence of PA once again. Spironolactone was instituted and blood pressure significantly improved and was finally controlled by the addition of amlodipine. Conclusion: We report this case to underline the difficulties in the discrimination between adenoma and hyperplasia in everyday clinical practice. Although the CT and scintigraphic findings strongly pointed toward an adenoma, the fact that PA re-appeared shortly after the operation, indicated that the underlying cause of the PA was hyperplasia and not adenoma after all.

Abstract The management of superficial femoral artery occlusive disease remains challenging for vascular surgeons. Despite the advances and dramatic changes we have seen in modern practice with the development and introduction of new endovascular techniques, long-term results with these interventions remain disappointing when compared to the “gold standard” of a vein bypass with a good run-off. Furthermore, there is little Level 1 evidence to guide us with regards to the best treatment strategy. In this article, we review some of the currently available open surgical and endovascular options for the management of superficial femoral artery disease.

We report the case of a 43-year-old woman who presented with mild left-sided abdominal pain. Computed tomography and MRI findings revealed a 10.7 × 8.5 × 12 cm left-sided soft tissue mass on the renal vessels pushing away the left kidney. The combination of the patient’s medical history (episodes of paroxysmal hypertension accompanied with dizziness and sweating) and radiological findings initially pointed toward the diagnosis of a paraganglioma or ectopic pheochromocytoma. Surgical removal of the tumor and left nephrectomy was performed. Histological findings were consistent with a renal vein leiomyosarcoma of a high malignancy grade. There is no evidence of local recurrence or metastatic disease for more than 2 years postoperatively, although the patient did not receive adjuvant chemotherapy or radiation therapy.

Primary aldosteronism (PA) is a common form of secondary hypertension. Several guidelines recommend that patients with adrenal incidentaloma have a high probability of suffering from PA. We conducted a prospective study of 269 consecutive adults with adrenal incidentaloma to investigate the prevalence and clinical characteristics of PA. In total, 9 participants were detected with PA, suggesting a prevalence of 3.35% among the study population. PA participants had a higher blood pressure level by 14/20.8 mm Hg and a lower serum potassium level by 0.8 mmol/L (P < .05). Importantly, all patients with PA presented with concurrent indications (hypertension with or without hypokalemia) for screening of the disease, but they have not undergone relative screening by the referring physician, thus casting doubts about the appropriate implementation of current guidelines in real‐life practice. Intense efforts are needed to familiarize physicians with recommendations for PA to minimize undiagnosed cases and the detrimental sequelae of this endocrine form of hypertension.
