AI Article Synopsis
- The study aims to compare the effectiveness of contrast-enhanced computed tomography (CECT) and endoscopic ultrasound (EUS) in assessing vascular involvement in patients with cephalo-pancreatic cancer, using intraoperative findings as a reference.
- Out of 425 patients with histologically confirmed pancreatic adenocarcinoma, the study focuses on the superior mesenteric artery, superior mesenteric vein, and portal vein for assessing potential tumor invasiveness.
- Both CECT and EUS displayed high accuracy rates in diagnosing vascular invasion, but their combination offered an even higher accuracy, suggesting that using both modalities together may improve diagnostic certainty.
Article Abstract
Aim: The aim of this study is to evaluate the information given by contrast-enhanced computer tomography (CECT) and ultrasound endoscopy (EUS) regarding vascular involvement of cephalo-pancreatic cancer, data compared with intraoperative findings.
Material And Methods: We choose to analyze the most often interested vessels by tumor development, such as superior mesenteric artery (SMA), superior mesenteric vein (SMV) and portal vein (PV). The patients included in the study (n=425) had a cephalo-pancreatic tumor diagnosed in our Institute and a positive histology for pancreatic adenocarcinoma. The exclusion criteria were: tumors in sites other than the head of the pancreas (including metastases); tumor involvement of common hepatic artery, celiac trunk, inferior cava vein or aorta; CECT or EUS diagnosis performed in another center; and a delay of more than 35 days between the diagnostic imaging and surgery.
Results: In diagnosing SMA invasion CECT had an accuracy of 84,92% and EUS had an accuracy of 87,39%. In diagnosing PV and SMV involvement, CECT had an accuracy of 84,83% and EUS had an accuracy of 92,17%. The accuracy of the two combined examinations in diagnosing vascular invasion was 93%.
Conclusons: Both types of examination have showed good accuracies in diagnosing vascular invasion separately. A combination of the two may be used when the CECT result is uncertain as it provides a higher chance of a correct diagnosis.
Key Words: Pancreatic cancer, Resectability criteria, Vascular invasion.

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.
Morbid Obesity and Liver Transplant.
Transplant Proc
January 2025
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.
