ABSTRACT
Acute mesenteric ischemia (AMI) remains a vascular emergency. Our aim was to explore readmission for AMI. We identified all patients admitted for AMI from the state of California through the Healthcare and Utilization Project from 2005 to 2011. Our primary end point was the rate and etiology for readmission. Our secondary end points were the length of hospitalization and in-hospital mortality. Cox proportional hazard regression was utilized to assess risk of 30-day readmission. There were 534 (9.9%) readmissions at 30 days. The mean age was 67 ± 17 years and 209 (39.1%) were male. The five most common etiologies for readmission were AMI (7.6%), cardiac events (5.3%), severe sepsis (1.2%), dehydration (1.1%), and acute kidney failure (1.1%). Once readmitted, these patients were most likely to experience cardiac catheterizations (25.4%), red blood cell transfusions (23.6%), intubation and mechanical ventilation (17.6%), biopsy of the large intestine (13.9%), reoperation for small bowel resection (10.9%), administration of total parenteral nutrition (10.5%), and transfusion of other blood products (6.9%). This hospitalization was 8.8 ± 12.7 days long. In-hospital mortality was 36 patients (6.7%). On multivariable Cox-regression analysis, severe (hazard ratio [HR]: 2.1 [1.4-3.2], p = 0.0005) and moderate (HR: 1.5 [1.03-2.13], p = 0.04) Elixhauser Comorbidity Group, complications (HR: 1.5 [1.2-1.9], p = 0.0007), and longer index hospitalization (HR: 1.02 [1.01-1.02], p < 0.0001) were predictors of readmission. Conclusion AMI remains a vascular emergency. Readmissions have a significant rate of morbid invasive procedures and can lead to an in-hospital mortality of 6.7%. The adoption of guidelines similar to the European Society for Trauma and Emergency Surgery should be considered.
ABSTRACT
BACKGROUND: A relationship between intracranial and abdominal aortic aneurysms (AAA) has been appreciated through genome-wide association studies suggesting a shared pathophysiology. However, the actual prevalence of AAA in patients presenting with ruptured intracranial aneurysms is not known. Our aim was to estimate the prevalence of previously undiagnosed AAA in patients presenting with aneurysmal subarachnoid hemorrhage (aSAH) to see if it may be high enough to justify formally testing the utility of screening. METHODS: A prospective, observational inception cohort study of 81 consecutive patients presenting to Mayo Clinic Florida with aSAH was performed from August 14, 2011 to February 10, 2014. These individuals were then screened using an abdominal ultrasound technique for an AAA. Our primary end point was detection of AAA. Our secondary end points were 30-day good-to-fair functional status (modified Rankin scale < 4) and all-cause mortality. RESULTS: We detected an AAA in 10 patients (rate: 12%; 95% CI 6-22%) with aSAH. The mean diameter of these AAA was 3.4 ± 1.0 cm. Among these 10 patients, there was one death within the first month of aSAH hospitalization. There were no significant differences in demographic or clinical characteristics based on AAA detection status. Mean follow-up time was 4.7 years. The rate of good-to-fair functional status at 30-days was 79%. All-cause mortality during follow-up at 1-year was higher for patients with AAA (36%; 95% CI 0-61%) compared to patients without AAA (7%; 95% CI 1-14%) (log-rank p = 0.045). CONCLUSIONS: The co-prevalence of AAA in patients presenting with ruptured brain aneurysms may be sufficiently high such that screening for AAA among likely survivors of aSAH might be appropriate. Larger studies would be needed to establish a net clinical benefit from screening AAA and then treating newly identified large AAAs in this morbid population.

INTRODUCTION: A case is reported of left brachiocephalic vein thrombus removal using the Angiovac device within a stented venous segment via a through-and-through access technique. REPORT: This novel technique involves obtaining through-and-through access from the left basilic vein to the right femoral vein, which then facilitates the advancement of the Angiovac device to successfully remove in a stepwise fashion the thrombus present within a stented region of the left brachiocephalic vein. DISCUSSION: The Angiovac device has been shown to be very useful and effective at removing large amounts of thrombus, tumor, and foreign bodies within arterial and venous systems successfully. This novel technique uses the through-and-through venous access approach to allow for this device to remain close to the targeted area of thrombus burden and prevent damage of the already existing stents in this region.
ABSTRACT
A 19-year-old immune-competent patient developed right-sided headache and, subsequently, subacute diplopia. On clinical examination he had incomplete right oculomotor palsy. Cranial MRI showed pathologic contrast enhancement of the right oculomotor nerve at its exit point from the mesencephalon, and the CSF displayed slight pleocytosis. The following relevant differential diagnoses were not supported by additional examinations: neurosarcoidosis, Lyme neuroborreliosis, neurosyphilis, tuberculous meningitis, viral meningitis (HIV, VZV, CMV), CNS lymphoma, vasculitis associated with rheumatic disease, Tolosa-Hunt syndrome, and diabetic neuropathy. However, on the basis of blood lymphocytosis, positive heterophile antibody test (Paul-Bunnell test), the presence of IgM antibodies against Epstein-Barr virus capsid antigen, and elevated transaminases, infectious mononucleosis was diagnosed. Isolated neuritis of the oculomotor nerve is a rare parainfectious manifestation of infectious mononucleosis.
