    Endovascular treatment of post-traumatic carotid-cavernous fistulae using latex detachable balloons
    (2005) Szkup, P; Beningfield, S
    Objective. To determine the efficiency of latex detachable balloons in the treatment of post-traumatic carotid-cavernous fistulae (CCF). Methods. Management and outcome were reviewed for 34 consecutive patients with post-traumatic CCF personally treated by one of the authors (PS) using latex detachable balloons during the 4-year period 1996 - 2000. Results. Endovascular embolisation of 34 CCFs was attempted in 33 patients. In 1 patient where the fistula was a result of rupture of an intracavernous aneurysm, the fistula thrombosed spontaneously before embolisation was attempted. In the 33 treated patients, the fistula was occluded in 30 cases (91%). Patency of the internal carotid artery was preserved in 16 cases (53%). Conclusion. A high percentage (91%) of direct CCFs were successfully occluded with latex detachable balloons. There were no permanent neurological complications in any of the patients treated.

    Interventive radiology in portal hypertension
    (2006) Beningfield, S
    Portal Hypertension can be successfully managed using a variety of interventional radiology techniques. The presinusoidal, sinusdoidal and post sinusoidal categories have different options available, as does segmental portal hypertension. The major role of TIPS has been tempered by early occlusions and high rates of hepatic encephalopathy .

    Liver biopsy - the current view?
    (2006) Beningfield, S
    Liver biopsy needs careful consideration for both focal and diffuse disease, particularly in surgically-resectable lesions and with core biopsies. Increasing perceptions of the risk of needle-track seeding are added to the chance of post-procedure haemorrhage. In high-risk patients, plugged biopsy or transjugular liver biopsy may reduce the chance of adverse outcomes.

    A retrospective study of CT angiography versus digital subtraction angiography in penetrating neck trauma
    (2013) Scholtz, Paul Victor John; Candy, S; Beningfield, S
    BACKGROUND. Penetrating neck trauma is commonly encountered in South African trauma units, and is associated with high mortality and morbidity rates. The imaging protocol for stable patients with penetrating neck trauma remains controversial. There is only sparse data validating the use of Computed Tomography Angiography (CTA) in the evaluation of penetrating neck trauma. OBJECTIVES. To assess the sensitivity and specificity of CTA versus Digital Subtraction Angiography (DSA) in detecting arterial injury and secondarily evaluate the ability of CT to assess non-arterial injury.
