Coronary artery fistula constitutes a rare congenital anomaly. The reported incidence of this anomaly ranges from 0.1% to 0.2% of the population undergoing coronary angiography. Coronary-pulmonary artery fistula is an extremely rare congenital anomaly of the coronary artery. Its real incidence is unknown. The authors report a case of coronary-pulmonary artery fistula that caused right heart failure in a 77-year-old woman. The fistula, arising from a proximal portion of the circumflex artery to the pulmonary artery, was sealed successfully using a Jostent (polytetrafluoroethylene-covered graft stent).

Total Pancreatectomy for Locally Advanced Pancreatic Adenocarcinoma with Coeliac Trunk Resection and Retrograde Gastric Revascularization Through Aorto-Hepato-Spleno Allograft.
Ann Surg Oncol

Background: Locally advanced pancreatic adenocarcinomas (LA-PDAC) are more frequently operated now than in the past because of new regimen chemotherapy and improvement in surgical technique. Resection of the coeliac trunk (CT) during pancreatoduodenectomy (PD) or total pancreatectomy (TP) is not routinely done owing to the risk of liver and gastric ischaemia. In this video, a patient with LA-PDAC underwent TP with CT resection and retrograde gastric revascularization through the distal splenic artery.

Objective: Brachial artery aneurysms are rare entities that have typically been associated with trauma, infection, arterio-venous fistula creation or connective tissue disorders. These aneurysms are often asymptomatic, but they can also cause local tenderness or thrombo-embolic events. Due to the very low incidence of true brachial artery aneurysms, there are no standardized guidelines on their optimal management.

Background: Calcification of the radial artery is one of the main causes of anastomotic stenosis in autogenous arteriovenous fistulas in uremic patients. However, the pathogenesis of calcification is still unknown. This study attempted to screen and validate the risk factors for vascular calcification in patients with uremia.

Introduction: Dural arteriovenous fistulas (dAVF) are abnormal anastomoses between meningeal arteries and dural venous sinuses. Typically, dAVF treatment involves an endovascular or microsurgical approach. Anterior ethmoidal artery (AEA) dAVFs pose unique challenges due to their anatomy and location.

Background: Modern pancreatic surgery has gradually changed with the introduction of neoadjuvant therapy. For patients with pancreatic cancer involving peripancreatic visceral arteries who have received neoadjuvant therapy, periarterial divestment has gradually gained popularity, which represents an alternative to arterial resection. There is ongoing debate about whether this approach achieves curative tumor resection comparable to that of arterial resection, and the differences in terms of postoperative complications and oncologic outcomes between the 2 surgical procedures.
