Complications in interventional radiology: early detection and effective intervention strategies.

This narrative review provides a comprehensive overview of complications in interventional radiology (IR), focusing on their aetiology, recognition, and management. As IR procedures continue to evolve and expand, understanding potential adverse events is crucial for improving patient safety and outcomes. The review will summarise various common complications associated with IR-based procedures, including their presentation, aetiology, and management.

Transcatheter arterial embolisation (TAE) to treat acute upper gastrointestinal bleeding secondary to gastric cancer: A systematic review and meta-analysis.

Introduction: Acute upper gastrointestinal bleeding (UGIB) secondary to gastric cancer presents a significant clinical challenge due to its high morbidity and mortality rates. Transcatheter arterial embolisation (TAE) has emerged as a potential therapeutic option for managing this condition, especially in the context of failed endoscopic management. This systematic review aims to evaluate the efficacy and safety of TAE in treating acute upper gastrointestinal (GI) bleeding caused by gastric cancer.

Isolated pulmonary artery choriocarcinoma masquerading as pulmonary embolism diagnosed by endovascular biopsy.

Pulmonary arteries may rarely be involved by primary and secondary tumors. Clinical and imaging features mimic those of PE making it challenging to diagnose. Choriocarcinoma is a malignant germ cell tumor, typically in the female genital tract.

Large bronchial artery-pulmonary artery fistula due to cavitating tuberculosis.

Bronchial artery-pulmonary artery fistulae are rare vascular malformations most commonly caused by infection. Our case presents a 57-year-old male who presented to the Emergency Department with a symptomatic bronchial artery-pulmonary artery fistula due to cavitating pulmonary tuberculosis (TB). The diagnosis was made with multiphase CT angiography of the thorax (including pulmonary and systemic arterial phases).

The Rolling Stones: A case report of two surgical abdomens linked by migrating gallstones.

Introduction: Acute abdominal pain accounts for 5% of all presentations to the emergency department (Stoker et al., 2009). Two of the most common causes are acute appendicitis and acute cholecystitis (Ferris et al.

Late presentation of 'Lemierre's syndrome': how a delay in seeking healthcare and reduced access to routine services resulted in widely disseminated infection during the global COVID-19 pandemic.

The SARS-CoV-2 outbreak has disrupted the delivery of routine healthcare services on a global scale. With many regions suspending the provision of non-essential healthcare services, there is a risk that patients with common treatable illnesses do not receive prompt treatment, leading to more serious and complex presentations at a later date. Lemierre's syndrome is a potentially life-threatening and under-recognised sequela of an oropharyngeal or dental infection.

Retrograde ureteric stent exchange in the female oncology patient by interventional radiology: the experience of a single tertiary referral centre.

Background: Double-J stents are used to treat ureteric outflow obstruction. Deployed in antegrade or retrograde fashion, they relieve ureteric obstruction in several conditions including ureteric calculi, strictures and malignancy. Traditionally exchanged in an operating theatre (OT) under general anaesthetic (GA), more recently described is the technique of using fluoroscopic guidance under sedation.

Comparison of outcomes and cost-effectiveness of trisacryl gelatin microspheres alone versus combined trisacryl gelatin microspheres and gelatin sponge embolization in uterine fibroid embolization.

Background: Uterine fibroid embolization (UFE) is an effective treatment for uterine leiomyomata. Optimizing the choice of embolic agents is imperative to achieve better patient outcomes with maximum resource utilization.

Purpose: To evaluate the efficacy and cost-effectiveness of trisacryl gelatin microspheres (TAGM) versus combined TAGM and gelatin sponge (GS) embolization in the treatment of symptomatic uterine leiomyomata.

Retrievable Inferior vena cava filters in pregnancy: Risk versus benefit?

Objective: Venous thromboembolism remains one of the leading causes of maternal mortality in the developed world. Retrievable inferior vena cava (IVC) filters have a role in the prevention of lethal pulmonary emboli when anticoagulation is contraindicated or has failed [1]. It is unclear whether or not the physiological changes in pregnancy influence efficacy and complications of these devices.

CIRSE Standards of Practice Guidelines on Gastrostomy.

Purpose: Surgical Gastrostomy has been around since the 19th century but in 1980 the first successful percutaneous endoscopic gastrostomy was reported. A year later the first successful percutaneous gastrostomy was performed using fluoroscopic guidance. The technique for percutaneous insertion and the equipment used has been refined since then and it is now considered the gold standard for gastrostomy insertion.

Out of Sight, out of Mind? An Audit Which Proposes a Follow-Up and Management Pathway for Inferior Vena Cava Filters.

Insertion of an IVC filter can be a safe and effective way to avoid PE in thrombosis patients who cannot be anticoagulated. If temporary filters are not promptly removed they can become difficult to remove, causing avoidable complications and often requiring lifelong warfarin. In this study, two sequential audits of retrieval of temporary IVC filters were conducted before and after the implementation of a coordinated management strategy for IVC filter follow-up.

Occupational radiation dose to eyes from interventional radiology procedures in light of the new eye lens dose limit from the International Commission on Radiological Protection.

Objective: In 2011, the International Commission on Radiological Protection (ICRP) recommended a substantial reduction in the equivalent dose limit for the lens of the eye, in line with a reduced threshold of absorbed dose for radiation-induced cataracts. This is of particular relevance in interventional radiology (IR) where it is well established that staff doses can be significant, however, there is a lack of data on IR eye doses in terms of Hp(3). Hp(3) is the personal dose equivalent at a depth of 3 mm in soft tissue and is used for measuring lens dose.

Fluoroscopically guided transurethral removal and/or replacement of ureteric stents in women.

Background: Traditionally double J ureteric stents have been removed and replaced via cystoscopy. Fluoroscopically guided procedures for the removal/replacement of stents using endovascular snare devices have previously been described as a successful alternative.

Purpose: To evaluate the technical and clinical success of fluoroscopically guided transurethral removal and/or replacement of ureteric stents in women.

Post-endoscopic biliary sphincterotomy bleeding: an interventional radiology approach.

Background: Endoscopic sphincterotomy is an integral component of endoscopic retrograde cholangiopancreatography. Post-sphincterotomy hemorrhage is a recognized complication. First line treatment involves a variety of endoscopic techniques performed at the time of sphincterotomy.

Transseptal transcatheter coil embolization of a symptomatic pulmonary arteriovenous aneurysm in a patient with hereditary hemorrhagic telangiectasia.

An atrial transseptal approach was used for embolization of a pulmonary arteriovenous aneurysm in a 56-year-old man with hereditary hemorrhagic telangiectasia. Two previous attempts at embolization of the aneurysm failed because of an inability to cannulate the feeding vessel. A transseptal puncture was performed to gain access to the left superior pulmonary vein allowing retrograde cannulation of the venous sac and successful coiling of the aneurysm without complications.

Magnetic resonance portal venography: use of fast-acquisition true FISP imaging in the detection of portal vein thrombosis.

Aim: To determine the accuracy of true fast imaging with steady-state precession (true FISP) in the diagnosis of portal vein thrombosis in patients with cirrhosis and compare it to contrast-enhanced three-dimensional (3D) magnetic resonance (MR) angiography, the reference standard.

Materials And Methods: Twenty-four consecutive patients with suspected portal venous thrombosis underwent contrast-enhanced 3D MR angiography and true FISP imaging of the portal vein. All patients had undergone at least one other imaging study, either computed tomography, (CT) or ultrasound.

Use of provocative angiography to localize site in recurrent gastrointestinal bleeding.

Background: While the source of most cases of lower gastrointestinal bleeding may be diagnosed with modern radiological and endoscopic techniques, approximately 5% of patients remain who have negative endoscopic and radiological investigations [1].

Clinical Problem: These patients require repeated hospital admissions and blood transfusions, and may proceed to exploratory laparotomy and intraoperative endoscopy. The personal and financial costs are significant.

An evaluation of the effects of renal artery stenting in renovascular hypertension.

Renal artery stenosis is a common cause (1-6%) of secondary hypertension. Renal artery stenting has recently been employed as an adjunct to antihypertensive medication. We evaluated 92 patients who underwent renal angiography of whom 30 were stented.

Treatment of "high-flow" priapism with superselective transcatheter embolization: a useful alternative to surgery.

Purpose: To review the efficacy of treatment of high-flow priapism with superselective transcatheter embolization.

Methods: Over a 2-year period, we reviewed five patients who were treated for traumatic high-flow priapism with superselective embolization. All patients underwent diagnostic angiography that demonstrated a communication between the cavernosal artery and the corpora cavernosa.

Low dose intraarterial thrombolysis with tissue plasminogen activator: does it deliver as promised?

The widespread use of intraarterial thrombolytic therapy has been based on perceived benefits over operative treatment and the downgrading of the magnitude of subsequent surgery. Thirty-three patients who had thrombolysis for peripheral artery occlusion were retrospectively analyzed at St. James's Hospital from 1991 to 1997.

Maxillary artery embolisation in the management of epistaxis.

Serious consideration needs to be given to the importance of early embolisation of the maxillary artery in severe and refractory epistaxis. This is particularly true in the young fit person with traumatic epistaxis and in the elderly person who is unfit for general anaesthesia. Embolisation is now a safe and reliable technique.
