RESUMEN
Transurethral resection of the prostate (TURP) is considered the gold-standard operation to treat lower urinary tract symptoms due to benign prostatic enlargement in men. Postoperative bleeding is a recognised complication and managing it is a core skill required by attending urologists. We report a rare case of postoperative bleeding caused by fistulating vessels to the prostate which developed after TURP. These fistulas arose from the right internal iliac vessels and communicated with pre-existing pelvic varices affecting the right paraprostaticand seminal vesicle tissues. The fistulating vessels were successfully embolised with liquid embolic agent. Surgeons should be aware that persisting haemorrhage can occur post-TURP from the rare presence of fistulating vessels communicating with pelvic varices. Early computed tomography angiographic assessment is warranted in cases where bleeding is prolonged and refractory to standard management in view of timely referral for percutaneous embolisation.

Inferior vena cava (IVC) filters are a controversial mechanical adjunct in the prevention of pulmonary embolism, the most serious result of venous thromboembolism. Despite modern IVC filters being in clinical use for more than 45 years, there is still uncertainty amongst many radiologists about the indications for IVC filter placement and their removal, particularly the more recent prophylactic use in patients without confirmed deep vein thrombosis (DVT) or pulmonary embolism (PE). Recently published guidelines on filter use from the National Institute of Health and Clinical Excellence (NICE) and other professional bodies are discussed. The vast majority of IVC filters in the UK are inserted by interventional radiologists, so radiologists may be the first point of contact for information requested by other clinicians. The increasing use of filters means that radiologists will encounter filters increasingly often during abdominal cross-sectional imaging. Awareness of common filter-related complications, such as tilting, thrombosis, and caval perforation, is useful to reassure or alert other clinicians. The potential role of filters in upper extremity DVT and requirement for concomitant anticoagulation is discussed.

Vascular malformations are a diffuse collection of abnormalities that are usually present at birth but may present any time during childhood or as an adult. Historically terminology has been complicated and used interchangeably causing confusion to patients and clinicians alike; however, a structured internationally agreed classification system exists. It is not uncommon for patients with vascular malformations to be referred to various specialties without obtaining a correct diagnosis and appropriate treatment. Vascular malformations can occur anywhere within the body and all patients will require imaging at some stage; therefore, it is important for all radiologists to be aware of the correct terminology and imaging characteristics. This review discusses classification and illustrates salient imaging findings and the modern approach to treatment of vascular malformations.

Clostridium difficile associated disease is an increasingly common cause of morbidity and mortality. Pseudomembranous colitis following hospital-administered antibiotic treatment is the most common symptomatic manifestation. Small bowel enteritis caused by C. difficile, however, is rarely described. Here, we present a series of four patients with hospital-acquired small bowel enteritis caused by C. difficile, discuss its CT and histopathological features, and review the current literature.

Palliation of malignant gastrointestinal obstruction is a major aspect of oncology. We assessed the efficacy of stents in the palliation of gastric outlet, duodenal and colonic obstruction. We undertook a retrospective study of 35 consecutive patients who were referred for stent insertion with palliative intent from June, 1999 to March, 2003. Thirty-two stents were successfully placed in 30 patients. Technical success rate was 86% (30/35 patients). Of the patients who had successful insertion, 83% had complete relief of symptoms. In 1 patient the stent failed to expand. There was no procedure related mortality. Median survival was 1.6 months (range, 0-14.8). The conclusion was that self-expandable metal stents provide an effective method of palliation in malignant gastrointestinal obstruction, with high clinical and technical success rates and low complication rates.
