Retrospective study at a single tertiary hospital in South Africa (Groote Schuur) on the treatment outcome in patients who underwent TransArterial Chemo-Embolization (TACE) for hepatocellular carcinoma
Background: Hepatocellular carcinoma is amongst the common causes of cancer deaths and has few curative treatment options. Transarterial chemoembolisation (TACE) is an option widely reported and used for palliative care and as a bridge to liver transplantation. Limited South African studies have …

Retrieving a Stent Navigating Deep Complications
… device was used for stent retrieval, with embolization to the right femoral artery during the process. POTENTIAL PITFALLS Operators should be aware of this potential complication and its management techniques. Stent dislodgement and migration should be rapidly identified and addressed …

Giving birth to a new approach: a retrospective comparison of radiation safety parameters between transradial and transfemoral approaches for uterine fibroid embolization at Groote Schuur Hospital, South Africa
Background: Uterine artery embolisation (UAE) is a recognised minimally invasive, effective and fertility preserving treatment option for patients with symptomatic uterine leiomyomas. The conventional transfemoral access (TFA) in UAEs remains the method of choice for the majority of South African …

Molecular imaging of spatio-temporal distribution of angiogenesis in hindlimb ischemia model and diabetic milieu
… time a cohort of animals underwent endovascular embolization for the establishment of hindlimb ischemia and were imaged with the aid of a MI radiotracer technique in order to deal with unresolved issues and establish the imaging protocol. The study included seven New Zealand White (NZW) rabbits …

The efficacy of intra-arterial lignocaine as an adjuvant analgesic in the management of post-procedural pain following uterineartery embolization for symptomatic uterine fibroids – a comparative study of outcomes
Background: Uterine artery embolisation (UAE) for symptomatic fibroids has been shown to be an effective and beneficial procedure in our South African population, especially considering any cultural stigma related to hysterectomy. Post procedural pain following UAE can be very significant. Regular …

Perioperative cell salvage blood transfusions in endonasal angiofibroma surgery at Groote Schuur Hospital
… patients with JNA were identified and underwent embolization prior to endoscopic resection. In all cases the intraoperative blood salvage apparatus was used. Close post-operative monitoring was performed.

Label-Free Functional Imaging Of Platelets At Nanoscale
… morphology during thrombus formation and embolization, along with platelets detachment, enables in-depth assessment of functional responses of platelets. In the first part of the thesis (Chapter 1-3), I shall describe the role of scattering in forming a microscopic image of a cell using …

Occlusion of the Internal Carotid Artery of Horses: Evaluation of a Technique Designed to Prevent Epistaxis Caused by Guttural Pouch Mycosis
… and carrier catheters withdrawn. Immediate embolization of the distal internal carotid artery was determined by lack of retrograde blood flow through the introducer sheath. The introducer sheath was withdrawn from the vessel and the proximal tourniquet was replaced with two ligatures. Horses …

Development of a static bioactive stent prototype and dynamic aneurysm-on-a-chip(TM) model for the treatment of aneurysms
… treatments include: (1) clipping, and (2) coil embolization, including stent-assisted coiling. While these procedures can be effective, it would be advantageous to design a biologically active stent, modified with magnetic stent coatings, allowing cells to be manipulated to heal the arterial …

Coiling and clipping in Aneurysmal Subarachnoid Hemorrhage
… were treated initially by endovascular coiling embolization, and 155 received clipping treatment. The percentage of aneurysm occlusions was divided into 100% or total occlusion, 95%–99% or subtotal occlusion, and less than 95% or incomplete occlusion. Clinical condition before treatment was …

Long term outcome and the validity of EuroSCORE II in native-valve surgery for active endocarditis in a South African cohort
… endocarditis includes valvular incompetence, embolization, cerebrovascular accidents and congestive heart failure and this has influenced the surgical options to a great extent. The EuroSCORE II is the current model available for predicting the early mortality after cardiac surgery. HYPOTHESIS: …

A Study to Demonstrate the Immediate Destination of an Embolus Formed in the Lumen of a Peripheral Venous Catheter
… small emboli from catheter irrigation to fatal embolization.</p> <p>The experimental method of research was used to collect data on twenty-two rabbits. Each rabbit was injected with a clot tagged with <sup>131</sup> I-MAA in the foreleg and later scanned to determine the location of each clot. …

The design and prototyping of a Transcatheter Aortic Valve Implantation training system specific for aortic valve regurgitation.
… critical as is can led to regurgitation or valve embolization which can potentially be fatal. It has been shown that the complication rate during TAVI reduces drastically after the first 100 implantation, hospitals with high volumes of TAVI have better outcomes. Surgeon proficiency in TAVI …
