CT guided sharp recanalization to restore dialysis access in patients with central venous obstruction: A single centre experience and review of alternative techniques.

Central venous obstructions that impedes catheter placement or results in catheter dysfunction is a significant problem for haemodialysis patients. Recanalization can be performed with an intent to restore central venous access, improve outflow from arteriovenous fistula or to relieve symptomatic venous obstructions. Sharp recanalization encompasses various interventional techniques using a sharp instrument to puncture through or bypass around a venous obstruction.

Magnesium implants in orthopaedic surgery create a diagnostic conundrum: A radiology case series and literature review.

During a routine post-operative orthopaedic radiograph reading session, repeated unusual radiographic soft tissue and bone appearances became evident. It was discovered that these patients had received biodegradable magnesium implants which have recently been introduced into orthopaedic clinical practice. To the untrained eye, the combination of peri-metallic bone resorption with associated soft tissue gas, could easily be mistaken for post-operative infection.

Can smoking cause impotence? a radiological retrospective cohort study comparing internal pudendal artery calcification on CT in male smokers versus non-smokers.

Background And Aims: This retrospective cohort study evaluated the degree of pelvic inflow and internal pudendal artery (IPA) calcification in male smokers versus non-smokers. As erectile dysfunction (ED) is strongly associated with IPA vascular, we wanted to investigate radiologically if there was a statistically significant difference in the degree of IPA calcification in smokers and potentially be a contributing factor in the cause of ED.

Methods: CT studies of 100 men aged between 40 and 60 years of age were blindly reviewed and assigned a calcium score of their vascular calcification levels.

CT-determined sarcopenia as a predictor of post-operative outcomes in patients undergoing an emergency laparotomy.

Purpose: Emergency laparotomy has a high reported thirty-day mortality, ranging from 11 to 15%. Current peri-operative risk assessment tools may poorly estimate the risk of perioperative mortality. We sought to determine if CT-determined sarcopenia may be a useful predictor of post-operative outcomes in patients undergoing an emergency laparotomy.
