Intraoperative endoprosthesis customization for repair of an aortoenteric fistula in an emergency context: a case report.

Aortoenteric fistula is a severe clinical condition and its management remains a major technical challenge for surgeons. In these cases, the conventional surgical approach is associated with high rates of morbidity and mortality. Endovascular surgery is an excellent option in these cases, but considering that the aorta has been treated previously, anatomy may not be compatible with commercially available endovascular devices and so physician-modified endografts may be needed in urgent cases.

Anatomic variant of the internal jugular vein and its importance in vascular access for hemodialysis.

The right internal jugular vein is considered the best route for vascular access, because of low complication rates and satisfactory flow during hemodialysis, due to its straight route to the right atrium. This paper reports the identification, prior to puncture, of an anatomic variant position of the internal jugular vein in relation to the common carotid artery. The benefit of this prior identification is highlighted, emphasizing the importance of performing vascular Doppler ultrasound rather than using only external anatomical observation for puncture of the internal jugular vein.

Crutch-induced arterial aneurysm is a rare event and there are no descriptions in the literature of cases with concomitant venous aneurysms. We report the case of a patient who, after prolonged crutch use, presented with acute ischemia of the upper limb secondary to brachial artery aneurysm thrombosis, associated with the incidental finding of brachial vein aneurysms. Although the main cause of acute upper limb occlusion is embolization of cardiac origin, consideration should be given to the possibility of arterio-arterial embolization due to an aneurysm induced by prolonged use of crutches.
