Successful treatment of superior mesenteric artery embolism depends on an aggressive approach in patients at risk for mesenteric ischemia. This approach favors an early diagnosis and permits the reestablishment of arterial flow within an appropriate time, with prevention of vasospasm and control of organic insufficiencies. We report here a case of superior mesenteric artery embolism in which arterial flow was reestablished by selective intra-arterial infusion of streptokinase. The literature has reported 18 similar cases thus far. This procedure could be an alternative to embolectomy in selected patients, i.e., patients with an early diagnosis, no evidence of intestinal necrosis and with partial occlusion and/or occlusion of secondary branches of the superior mesenteric artery. Frequent arteriographies and intensive care are necessary in this approach. The patient should be continuously monitored because of the possibility of treatment failure and the need for embolectomy.

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.

Hepatobiliary Surgery and Liver Transplantation Unit, Cruces University Hospital, Bilbao, Spain. Electronic address:
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.
