Intestinal angiodysplastic lesions represent one frequent source of gastro-enteric tract serious bleedings, endowed with present-day therapeutic implications. The Authors report a singular case of a bleeding of this kind. A selective arteriography analysis of the superior mesenteric artery immediately pointed out the necessity for a surgical intervention, which however has not proved being resolutive for recovery, because massive intestinal hemmorrhage recurrence occurred. The left gastric artery anomalous origin, being discovered in the first branch of the mesenteric artery, which was not recognized fully in advance, stressed, in fact, the need for a partial gastrectomy, firstly, and a full gastrectomy, subsequently. The post-surgery course got more serious for a small leak of the oesophageus-digiunal anastomosis and for a serious renal failure. NPT and haemodialysis helped to quickly solve those complications. Other hemorrhagic events have not occurred anymore, 5 years having passed since the surgical intervention.

Paternal alcohol exposure affected offspring mesenteric artery via ROS-Cacna1c and DNA hypomethylation.

Institute for Fetology, The First Affiliated Hospital of Soochow University, Jiangsu.
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.

Purpose: To explore the information in routine digital subtraction angiography (DSA) and evaluate deep learning algorithms for automated identification of anatomic location in DSA sequences.
Methods: DSA of the abdominal aorta, celiac, superior mesenteric, inferior mesenteric, and bilateral external iliac arteries was labeled with the anatomic location from retrospectively collected endovascular procedures performed between 2010 and 2020 at a tertiary care medical center. "Key" images within each sequence demonstrating the parent vessel and the first bifurcation were additionally labeled.
Encountering Arc of Bühler during pancreaticoduodenectomy surgery.

The Arc of Bühler (AoB) is a rare anatomical variant in gastrointestinal vasculature where there is an aberrant anastomotic vessel between coeliac and superior mesenteric arteries. We present a rare case where AoB was noted intraoperatively to have haemodynamically significant flow in the context of coeliac artery stenosis, supplementing arterial supply to the hepatic artery proper via the gastroduodenal artery (GDA). An interpositional jump graft between the aorta and the GDA stump was created using the long saphenous vein, and flow was restored.

Stent-graft implantation is a widely recognized method for endovascular treatment of aortic aneurysms. In cases where the aneurysm involves the thoracic and abdominal aorta, repair including fenestrated and branched stent grafts provides a viable alternative. This approach, initially reserved for patients unsuitable for open surgery, has become preferred for anatomically appropriate thoracoabdominal aortic aneurysms.
