We identified 14 cases of infective haemodialysis CRAT, and their characteristics are summarised in Table I. The median age of the patients was 59 (range 47-88) years and 11 (78.6%) INTRODUCTION Infective haemodialysis catheter-related right atrial thrombus (CRAT) is a complication of tunnelled catheter use. Management recommendations are based mainly on published case series prior to 2011. We report our institution's recent experience in managing infective haemodialysis CRAT and correlate treatment with outcomes. METHODSWe conducted a retrospective analysis of haemodialysis CRAT cases diagnosed on transthoracic echocardiography between 1 January 2011 and 31 December 2017. Clinical outcomes, including mortality at 180 days post diagnosis and thrombus resolution, were traced from electronic medical records. RESULTSThere were 14 cases identified. The median age was 59 (range 47-88) years and 11 (78.6%) were male. Sepsis was the most common reason for hospitalisation (71.4%). Blood cultures identified Staphylococcus aureus in seven cases, of which two were methicillin-resistant. Three had coagulase-negative Staphylococcus. All cases received antibiotics with infectious disease physician input. Seven were treated with catheter removal alone, of which three died within 180 days. Both cases treated with catheter removal plus anticoagulation survived at 180 days. Of the two cases who had anticoagulation without catheter removal, one died within 180 days and the other did not have thrombus resolution. Three underwent surgical thrombus removal, of which two died postoperatively and the last required repeated operations and prolonged hospitalisation. Mortality at 180 days post diagnosis was 42.9%.CONCLUSION Catheter removal and anticoagulation are modestly effective. Surgery is associated with poor outcomes. Despite contemporary management, infective haemodialysis CRAT still results in high mortality. Prospective studies are needed to identify the optimal management.

Recent advances in stent technology have led to the development of thin strut platforms with fewer connectors. This has improved delivery but compromised strength, as illustrated by recent cases of longitudinal compression. We present an unusual case of longitudinal shortening at the distal end of a Synergy stent.

A 60-year-old Chinese woman presented with a 3-week history of painful rash over her lower abdomen and thighs. Her medical history included ischemic heart disease, severe atherosclerosis with chronic occlusion of the infrarenal aorta, diabetes mellitus, hypertension, and hyperlipidemia. Physical examination revealed erythematous to dusky-brown, non-blanchable patches on the hips and thighs, and reticulated macular streaks on the lower abdomen (Fig. 1). Some of the dusky patches subsequently developed necrosis and ulceration.
