Endovascular management of visceral aneurysms is an effective means of treating aneurysms involving branches of the celiac and superior mesenteric arteries and is particularly useful in patients with comorbidities, including cancer. It is associated with a decreased length of stay in the elective setting, and failure of primary treatment can often be successfully managed percutaneously.

We observed that type II endoleaks have a relatively benign course, and in the absence of sac expansion, can be followed for a prolonged course of time without the need for intervention. The rate of spontaneous seal continues to increase with time and, therefore, close follow-up of patients with type II endoleaks who show no signs of aneurysm expansion is a safe approach. For patients in whom the exact etiology of their endoleak is in question, dynamic imaging should be used to exclude the presence of a type I endoleak.

The present study was aimed to investigate pregnancy outcome among obese women and specifically the correlation between maternal obesity and incidence of caesarean section (CS) while controlling for the potential confounding effects of other variables associated with obesity. A population-based study was performed comparing all pregnancies of obese (maternal pre-pregnancy body mass index (BMI) of 30 kg/m2 or more) and non-obese patients, between the years 1988 and 2002. Patients with hypertensive disorders and diabetes mellitus as well as patients lacking prenatal care were excluded from the analysis. Stratified analyses, using the Mantel-Haenszel technique, and a multiple logistic regression model were performed to control for confounders. During the study period there were 126,080 deliveries meeting the inclusion criteria, of which 1769 (1.4%) occurred in obese patients. Using a multivariable analysis, the following conditions were significantly associated with maternal obesity: failure to progress during the first stage (odds ratio (OR) = 3.1; 95% confidence interval [CI] 2.5, 3.8; P < 0.001), fertility treatments (OR = 2.0; [95% CI 1.6, 2.5]; P < 0.001), previous CS (OR = 1.7; [95% CI 1.5, 1.9]; P < 0.001), malpresentations (OR = 1.4; [95% CI 1.2, 1.6]; P < 0.001), recurrent miscarriages (OR = 1.4; [95% CI 1.2, 1.7]; P < 0.001) and fetal macrosomia (OR = 1.4; [95% CI 1.2, 1.7]; P < 0.001). Higher rates of caesarean deliveries were found among obese parturients (27.8% vs. 10.8%; OR = 3.2; [95% CI 2.9, 3.5]; P < 0.001). When controlling for possible confounders, using the Mantel-Haenszel technique, the association between maternal obesity and CS remained significant. No significant differences were noted between the groups regarding perinatal complications such as perinatal mortality, congenital malformations, shoulder dystocia and low Apgar scores. In conclusion, a significant association was found between obesity and CS even after the exclusion of hypertensive disorders and diabetes mellitus. Importantly, obesity alone was not associated with adverse perinatal outcome. Obstetricians should be encouraged to allow obese patients not suffering from diabetes or hypertensive disorders an adequate trial of labour.

Most patients presenting with acute kidney infarction are managed conservatively. A subset of patients with complete occlusion of the renal artery undergo CDT with good angiographic results. The treated kidney is expected to decrease in size over time, and overall kidney function is expected to decrease compared with baseline. Deterioration in renal function appears to stabilize and does not continue over time. CDT for acute renal artery occlusion is a safe modality of therapy and should be attempted for the purpose of kidney salvage, even in the setting of prolonged ischemia.
