Background: Superior mesenteric artery embolism (SMAE) is a rare cause of acute abdomen, and the fatality rate is extremely high if it is not diagnosed and treated in time. Due to the lack of knowledge and experience of nonspecialist physicians, it is easy to misdiagnose. Radiofrequency ablation (RFA) has become the first-line treatment strategy for atrial fibrillation (AF). Thromboembolic events are some of the major complications after RFA, whereas SMAE is rarely reported.
Case Presentation: A 70 year-old woman with paroxysmal AF who regularly took anticoagulant drugs for 3 months experienced abdominal pain after RFA. At the outset, she was misdiagnosed as mechanical intestinal obstruction. When the patient presented with blood in the stool, abdominal enhancement computed tomography was conducted and showed a small bowel perforation. Immediate laparotomy was performed, and the final diagnosis was SMAE.
Conclusion: It is suggested that for unexplained abdominal pain after RFA of AF, the possibility of SMAE should be considered, and a targeted examination should be carried out in time to confirm the diagnosis and give appropriate treatment.

Long-Term Outcomes of Endovascular Aortic Repair with Parallel Chimney or Periscope Stent Grafts for Ruptured Complex Abdominal Aortic Aneurysms.
J Clin Med
January 2025
Department of Vascular Surgery, University Hospital Zurich, 8091 Zurich, Switzerland.
: The parallel stent graft endovascular aortic repair (PGEVAR) technique is an off-the-shelf option used for elective complex abdominal aortic aneurysm repair with acceptable outcome results, as reported so far. The PGEVAR technique, using chimney or periscope parallel grafts, can also be used for patients with ruptured complex abdominal aortic aneurysms. However, only few data about the mid- to long-term outcomes are available.

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.

Department of Radiology, UC Davis School of Medicine, University of California, Davis, 4860 Y Street, Suite 3100, Sacramento, CA, 95817-2307, USA.
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.

Background: The progressive increase in the prevalence of morbid obesity (MO) in the general population is a pressing issue. This rise in MO has also been observed in patients with liver disease who are candidates for liver transplantation (LT).
Methods: A retrospective study of a single-center series was conducted to analyze the impact of MO on morbidity, mortality, and patient survival after LT.
Encountering Arc of Bühler during pancreaticoduodenectomy surgery.
BMJ Case Rep
January 2025
Upper Gastrointestinal Surgery Unit, Royal North Shore Hospital, St Leonards, New South Wales, Australia.
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.
