case of persistent urogenital sinus: pitfalls and challenges in diagnosis

Persistent urogenital sinus [PUGS] is a rare anomaly whereby the urinary and genital tracts fail to separate during embryonic development. We report a three-year-old female child who was referred to the Sabah Women and Children Hospital, Sabah, Malaysia, in 2016 with a pelvic mass. She had been born prematurely at 36 gestational weeks via spontaneous vaginal delivery in 2013 and initially misdiagnosed with neurogenic bladder dysfunction. The external genitalia appeared normal and an initial sonogram and repeat micturating cystourethrograms did not indicate any urogenital anomalies. She therefore underwent clean intermittent catheterisation. Three years later, the diagnosis was corrected following the investigation of a persistent cystic mass posterior to the bladder. At this time, a clinical examination of the perineum showed a single opening into the introitus. Magnetic resonance imaging of the pelvis revealed gross hydrocolpos and a genitogram confirmed a diagnosis of PUGS, for which the patient underwent surgical separation of the urinary and genital tracts

Post-transarterial chemoembolization [TACE] biloma mimicking liver abscess: the role of different imaging modalities

Transarterial chemoembolization [TACE] is a recognized mode of treatment for patients with hepatocellular carcinoma. Complications related to the procedure such as liver failure, liver abscess, bile duct infection or even pulmonary embolism are known to cause morbidity and mortality in these patients. Biloma is a rare complication of TACE. Its incidence has been reported as between 0.9 - 2.1%. It is caused by injury to the arterial supply of bile duct, which then forms a bile-contained cavity either intra-hepatic or extra-hepatic in location. We report the case of a patient with recurrent hepatocellular carcinoma who was treated with TACE. He developed an infected biloma post-procedure. He had different imaging modalities that pointed to the diagnosis of biloma. He underwent appropriate management that led to resolution of the biloma

Value of CT pulmonary arteriography and venography in the evaluation of venous thromboembolism in a multiracial Asian population / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>There is increasing evidence that CT pulmonary arteriography and venography allow a better diagnostic yield for deep vein thrombosis (DVT) in suspected acute pulmonary embolism (PE). The aim was to investigate the value for using such an approach in a multiracial Asian population.</p><p><b>METHODS</b>A total of 135 consecutive subjects with clinically suspected PE in various clinical settings (postoperative in 23 subjects) were referred and evaluated for venous thromboembolism using CT pulmonary arteriography and venography in a tertiary hospital, Malaysia. The distribution of DVT was assessed based on the frequency rate of thrombosis in a particular anatomical region (inferior vena cava, pelvic, femoral and popliteal).</p><p><b>RESULTS</b>In 130 subjects, excluding 5 subjects having poor images, both DVT and PE were detected in 11.5% (15/130) subjects and DVT alone was detected in 6.9% (9/130) subjects giving a combined rate of venous thromboembolism of 18.4%. A history of malignancy was significantly associated with positive scans, P = 0.02. It was found that left pelvic veins (18.2%) and left femoral veins (19.5%) were more commonly thrombosed in this population.</p><p><b>CONCLUSION</b>CT pulmonary arteriography and venography is a useful technique in the evaluation of venous thromboembolism in a multi-racial Asian population.</p>

Endovascular Treatment of Cerebral Aneurysm: Early Experience in a Malaysian Tertiary Centre

Universiti Kebangsaan Malaysia Medical Center (UKMMC) started neurointerventional service in August 2008. In this study, we aimed to evaluate the immediate and short term outcome of endovascular treatment (EVT) of cerebral aneurysm during early period of the services. A retrospective study for cerebral aneurysm treated by endovascular technique, from the Neurosurgical and Radiology Department from September 2008 till February 2010 was performed. Patient’s demographic data, initial clinical presentation and assessment of the aneurysm were performed. The immediate results and short term assessment post EVT were evaluated based on standard criteria. Recurrence and complications during and following EVT procedures, were recorded. Twenty one patients with total of 22 aneurysms were treated. The mean age was 54.52 years with 57% being males and 43% females. The majority (81%) had single aneurysm. The most common site was anterior communicating artery (28 %). Mean aneurysm sac size was 6.19 mm and 2.55 mm for aneurysm neck. At follow-up, 3 (27.2%) had a small residual neck. Four patients (37.2%) had residual aneurysm filling, but three of them were treated with stent aiming to achieve flow diversion effect instead of complete occlusion during initial treatment. There was no rebleed or rupture from the immediate to follow-up. Significant complications up to 30-days was observed in 4 patients (20%) whereby 2 patients showed improvement and 2 patients died (10 % mortality rate). Endovascular treatment of cerebral aneurysms performed in our centre had early outcome, morbidity and mortality compared to other higher volume centres. Longer term follow up is needed to evaluate the long term outcome/occlusion rate, morbidity and mortality.

The Vanishing Veins: Difficult Venous Access in a Patient Requiring Translumbar, Transhepatic, and Transcollateral Central Catheter Insertion

Central venous catheter placement is indicated in patients requiring long-term therapy. With repeated venous catheterisations, conventional venous access sites can be exhausted. This case illustrates the expanding role of radiology in managing difficult venous access. We present a case of translumbar, transhepatic, and transcollateral placement of central catheter in a woman with a difficult venous access problem who required lifelong parenteral nutrition secondary to short bowel syndrome. This case highlights the technical aspects of interventional radiology in vascular access management.

Y-Stent–Assisted Coil Embolisation of Wide-Necked Aneurysms Using a New Fully Retrievable and Detachable Intracranial Stent: Report of Two Cases

Endovascular treatment of wide-necked aneurysms poses a challenge for the endovascular therapist. The Y-stent–assisted technique has been used for stent-assisted coil embolisation for wide-necked bifurcation aneurysms. This technique has been described for basilar tip aneurysms and middle cerebral artery bifurcation aneurysms using Neuroform and Enterprise stents. We report 2 cases of wide-necked bifurcation aneurysms that were treated with Y-stent–assisted coil embolisation using a new, fully retrievable and detachable intracranial stent (Solitaire ABTM). We describe the advantages of a fully retrievable and detachable stent and its feasibility of forming a Y configuration.

Superselective Embolisation in Acute Lower Gastrointestinal Haemorrhage: A Single Institution Experience

Background: Superselective embolisation has been recognised as integral in the management of lower gastrointestinal haemorrhage. It has also reduced the need for emergency surgery. The objective of this case series was to describe the lower gastrointestinal haemorrhage cases seen in our centre, its diagnosis and the role of superselective embolisation in patient management. Methods: All patients who underwent superselective embolisation from January 2008 until April 2009 in our centre were analysed. Data were collected from the hospital electronic medical records. Results: Four patients (three males) with a mean age of 81 years were analysed. Multidetector computerised tomography and digital subtraction angiography were positive in all patients. Superselective embolisation with platinum microcoils was performed in all patients (n = 4). Technical success was achieved in all patients (100%). Conclusion: Superselective embolisation in the treatment of lower gastrointestinal haemorrhage is safe and effective with a very high technical success rate.
