BACKGROUND: This study was aimed to determine risk factors for the recurrence of an intracranial saccular aneurysm (ISA) following endovascular treatment. The findings will help medical professionals to identify patients having a high risk of ISA recurrence and assist them in developing appropriate follow-up plans. RESULTS: During the follow-up period, 12.6% of the patients (83/658) experienced recurrent ISAs. An analysis of related factors, including gender, age, hypertension, diabetes mellitus, smoking, tumor size, width of the aneurysm neck, the presence or absence of a rupture, the volume embolization ratio (VER), the application or nonapplication of a stent, and follow-up time, revealed that a tumor size > 10 mm in diameter, wide-necked aneurysms, an anterior communicating or middle cerebral artery aneurysm, an aneurysm rupture, a VER < 20%, the absence of stent assistance, and follow-up time were high-risk factors for the recurrence of ISAs...

The use of marginal kidneys or kidneys with pathologic problems (such as renal artery aneurysms in a living or deceased donor) is on the rise due to organ shortages and improvements in surgical techniques. When renal vascular abnormalities are detected during a transplant, it puts the surgeon in a difficult position to decide what to do with the organ. In this study, we report a case of a kidney from a deceased donor who had 2 renal artery saccular aneurysms, which we were able to use for transplant. The recipient was a 61-year-old male patient with diabetic nephropathy and significant comorbidities...

INTRODUCTION: Diabetes mellitus is a well-defined risk factor for peripheral artery disease (PAD), but protects against the development and growth of abdominal aortic aneurysm (AAA). Diabetes mellitus is associated with arterial stiffening and peripheral arterial media sclerosis. Advanced glycation end-products (AGEs) are increased in diabetes mellitus and cardiovascular disease. AGEs are known to form cross-links between proteins and are associated with arterial stiffness. Whether AGEs contribute to the protective effects of diabetes mellitus in AAA is unknown...

BACKGROUND: Although recent guidelines recommend EVAR for robust younger patients, we have been limiting our indication to older patients or those who are physically frail. This study compares long-term outcomes of our series of abdominal aortic aneurysms (AAA) treated with endovascular repair (ER) and open surgery (OS), using propensity-score matching. METHODS: Between June 2007 and October 2014, 819 patients with infrarenal AAA underwent elective repair at our institution...

OBJECTIVE The recurrence rate of vertebrobasilar dissecting aneurysms (VBDAs) after reconstructive endovascular treatment (EVT) is relatively high. The aneurysm wall enhancement on high-resolution MRI (HRMRI) reportedly predicts an unsteady state of an intracranial aneurysm. The authors used HRMRI to investigate the relationship between wall enhancement on HRMRI and progression of VBDAs after reconstructive EVT. METHODS From January 2012 to December 2015, patients with an unruptured VBDA who underwent reconstructive EVT were enrolled in this study...

Vessel segmentation is a critical task for various medical applications, such as diagnosis assistance of diabetic retinopathy, quantification of cerebral aneurysm's growth, and guiding surgery in neurosurgical procedures. Despite technology advances in image segmentation, existing methods still suffer from low accuracy for vessel segmentation in the two challenging while common scenarios in clinical usage: (1) regions with a low signal-to-noise-ratio (SNR), and (2) at vessel boundaries disturbed by adjacent non-vessel pixels...

Epidemiological studies show that type 2 diabetes (T2D) is inversely associated with intracranial aneurysms (IA) and abdominal aortic aneurysms (AAA). Although adiposity has not been considered a risk factor for IA, there have been inconsistent reports relating adiposity to AAA risk. We assessed whether these observations have a genetic, causal basis. To this end, we extracted genotypes of validated single-nucleotide polymorphisms associated with T2D (n=65), body mass index (BMI) (n=97) and waist-hip ratio adjusted for BMI (WHRadjBMI) (n=47) from genotype data collected in 717 IA cases and 1988 controls, and in 818 AAA cases and 3004 controls, all of Dutch descent...

A 38-year-old Japanese man who had undergone clipping surgery for a ruptured aneurysm of the anterior communicating artery 2 days prior, suddenly developed refractory hypernatremia (serum sodium (Na) 156 - 162 mmol/L). Symptoms included low plasma vasopressin, fluctuating urine osmolality (120 - 710 mOsm/kg) and lack of thirst, all suggesting adipsic diabetes insipidus (ADI). Hypernatremia was corrected by scheduled water intake with desmopressin administration. During 1-year follow-up after the surgery, his serum Na level normalized despite the suspension of desmopressin, but neither thirst nor osmolality-dependent vasopressin release recovered...
