We report a case of mesenteric ischemia after thoracic endovascular aortic repair (TEVAR) for chronic type B aortic dissection performed at a different institution. Computed tomography angiography findings indicated that the previous TEVAR had been deployed distally into the false lumen. To mitigate this, a large fenestration was created between the false lumen and true lumen.

A 55-year-old woman with non-small cell lung carcinoma complained of epigastric pain, bloating, anorexia and postprandial nausea and vomiting over a five-year period. An upper gastrointestinal pan-glucosamine contrast examination revealed a distinctive large, hook-shaped, ptotic gastric lumen with normal motility. The contrast agent demonstrated an abnormal round-trip flow anterior to the spine at the duodenal level, with pooling and gradual passage through this region in strands after prolonged retention.

Background: Paternal preconception alcohol exposure affects fetal development; however, it is largely unknown about the influences on offspring vasculature and mechanisms.
Methods: Offspring born form paternal rats treated with alcohol or water before pregnant was raised until 3 months of age. Vessel tone of mesenteric arteries was detected using myograph system; whole-cell calcium channel current in smooth muscle cells was tested using patch-clamp; molecule expressions were detected with real-time PCR, western blotting, and Dihydroethidium (DHE); DNA methylations were determined using targeted bisulfate sequencing assay.

In renal vasculitis, luminal narrowing can reduce blood flow and activate the renin-angiotensin-aldosterone system, causing renovascular hypertension. We present the case of a 47-year-old man with previous intestinal tuberculosis and episodes of lumbar pain, tender erythematous nodules and arthralgias. He had grade 3 hypertension, unresponsive to treatment, with left ventricular concentric hypertrophy and chronic kidney disease.

Currently, there are no large epidemiological studies looking specifically at traumatic visceral AVFs. When traumatic AVFs have been discussed in the literature, it is in the form of case reports or case series and focused on peripheral AVFs.
