Large vessel vasculitis (LVV) is a group of inflammatory diseases that affect the aorta and its major branches, causing stenosis, aneurysms, or dissections. LVV can be associated with various disorders, such as IgG4-related disease, Takayasu arteritis, giant cell arteritis, and Behcet's disease. Aneurysms due to Behcet's disease are rare and challenging to manage, as they have high rates of morbidity and mortality.

In this case report we will discuss the case of a 47-year-old woman who presented with abdominal pain, nausea, oliguria and right heart failure. A Computed Tomography (CT) aortogram revealed a fistulous abdominal aortic aneurysm. The objective of this study is to discuss the haemodynamic changes regarding aortocaval fistula and consider various management options.

Injuries deeper than the platysma are considered as penetrating neck injuries, constituting approximately 5% - 10% of all trauma. Many vital organs are at risk from a penetrating neck injury. These injuries in zone 1 have the highest mortality, because the injuries are close to the vital organs and difficult to access surgically.

Introduction: Forearm basilic vein transposition (FBVT) is a viable alternative for arteriovenous grafts (AVGs) and can be used as secondary vascular access as well, as it allows for the use of veins that are remote from the arterial source of inflow. FBVT involves two main steps: first, the basilic vein is dissected from its original location; and second, the basilic vein is transposed to a subcutaneous tunnel on the volar aspect of the forearm and anastomosed to a suitable artery, usually the radial or ulnar artery.

Objective: This paper aims to present a series of FBVT cases performed at our hospital and present it as a viable option for secondary vascular access.

Fenestrated grafts form an alternative to open surgery, and are already increasingly being offered as part of the standard spectrum of treatment in developed countries. The past two decades have seen rapid developments in fenestrated endovascular aneurysm repair (fEVAR)/branched (bEVAR) expertise, to the point where the results are striking and can compete with those of conventional surgery. We here report the case of an 82-year male, who was diagnosed with an abdominal aortic aneurysm 10 years ago.

Traumatic aortic injury (TAI) or aortic transection is the second most common cause of death after blunt trauma. The conventional management approach towards a thoracic aortic injury is open thoracotomy and surgical repair; however, there is a recent increase in the trend towards the use of endovascular approach in this regard, particularly in the developed countries. We here report the cases of two young healthy male patients presenting in emergency department with thoracic aortic injury, following a road traffic accident (RTA).

Purpose: The Department of Health estimates that currently in the UK, 61.3% of the population are overweight or obese (BMI >25 kg/m2). Fistulae in the obese often fail to mature or prove inadequate to needle due to excessive depth (>6 mm).

Since the first published report of a fenestrated endovascular aneurysm repair, we have seen an expansion in the range of custom-made devices used to manage complex aortic aneurysms. Fenestrated devices, branched devices, and chimneys are now frequently used in many centers to repair these aneurysms. Similar to standard endovascular aneurysm repair, the advantages of less operative blood loss, decreased hospital stay, and reduced risk of morbidity and mortality hold true for endovascular repair of complex aneurysms as well.

Ankle arthroscopy is believed to have the least vascular complications compared with other types of arthroscopies. We present a case of traumatic pseudoaneurysm of the anterior tibial artery after ankle arthroscopy, an extremely rare complication that was treated surgically and had an uneventful recovery.
