Superselective embolization of visceral arterial branches has become integral in the management of acute lower gastrointestinal (GI) hemorrhage. The present study aimed to evaluate the success of superselective embolization as a primary therapeutic modality in the control of lower GI hemorrhage and to identify factors associated with rebleeding and surgical(More)
BACKGROUND Thoracic aortic injury from blunt trauma is a life-threatening condition with significant mortality and morbidity with open surgical repair. Endovascular means of treatment is emerging as an attractive and less invasive option. We report our experience with endovascular stent-graft repair for blunt traumatic thoracic aorta injury. METHODS(More)
INTRODUCTION Lower extremity amputation prevention (LEAP) is an ongoing programme in our institution aimed at limb salvage in patients with critical limb ischaemia (CLI). Patients in the LEAP programme with reconstructible anatomy on initial Doppler imaging received either bypass surgery or percutaneous transluminal balloon angioplasty (PTA). We describe(More)
OBJECTIVE This study aimed to evaluate the perioperative and long-term outcomes associated with extrapleural pneumonectomy for patients with malignant pleural mesothelioma. METHODS From October 1994 to April 2008, 70 patients were selected for extrapleural pneumonectomy. Univariate analysis was performed using the Kaplan-Meier method and compared using(More)
Amiodarone, a commonly used antiarrhythmic agent, has numerous adverse effects. The purpose of this case report is to highlight its hepatotoxicity, an unusual complication of long term amiodarone therapy. Our patient is a 76-year-old man with underlying ischaemic heart disease and recurrent ventricular tachycardia. Eleven months after commencing amiodarone,(More)
INTRODUCTION Mycotic aneurysms are associated with high mortality rates and are managed in the local setting with extra-anatomical bypass followed by ligation, exclusion and debridement of the aneurysm. This is the first case of successful endovascular stenting in an immunocompromised patient with Salmonella mycotic aneurysm. CLINICAL PICTURE A(More)
INTRODUCTION The purpose of this retrospective study was to evaluate the short- to mid-term results of the endovascular repair of thoracic aortic disease and to present an overview of our experience with thoracic endovascular aortic repair (TEVAR) in our institution. MATERIALS AND METHODS A retrospective review of all patients who were treated and(More)
Elective abdominal aortic aneurysm (AAA) surgery may result in substantial blood loss. Concerns regarding the safety, availability, and acceptability of homologous blood have led to initiatives toward reducing transfusion requirements at the time of aneurysm repair. This study was designed to determine if the routine use of intraoperative red cell salvage(More)
BACKGROUND The purpose of this study was to determine the effect of postoperative radiotherapy (PORT) on recurrence and survival in patients with oral squamous cell carcinoma (OSCC) of intermediate recurrence risk. METHODS Intermediate risk patients, defined as pT1, pT2, pN0, or pN1 with at least one adverse pathological feature (eg,(More)
