BACKGROUND: Treatment of basilar artery aneurysms is challenging. While endovascular techniques have dominated, there still remain circumstances where open surgical clipping is required or preferred. Minimally invasive "keyhole" approaches are being used more frequently to provide the durability of surgical clipping with a lower morbidity profile; however, careful patient selection is required. The supraorbital "keyhole" approach has been described for the treatment of basilar artery aneurysms, but careful assessment of the basilar exposure is necessary to ensure proper visualization of the aneurysm and ability to obtain proximal vascular control...

The case of an elderly male diagnosed with a large iatrogenic pseudoaneurysm arising from the profunda femoris artery on ultrasound examination is presented. The immediate postoperative period was uneventful; however later he developed leg swelling and mild oozing at the incision site. In view of deranged renal function CT angiogram was not done and decision was made to treat the pseudoaneurysm with percutaneous thrombin injection. Almost complete thrombosis was achieved however a small residual portion remained patent near the neck...

PURPOSE: To investigate pulmonary venous anomaly as a cause of pulmonary arteriovenous malformation (PAVM) misdiagnosis. MATERIALS AND METHODS: We reviewed adult patients within a 7.5-year period with CT scans initially diagnosed with PAVM and subsequent conventional pulmonary angiograms. RESULTS: Pulmonary arteriography showed no PAVM on arterial phase for 10 out of 99 patients, comprising the misdiagnosed group. Four misdiagnosed patients had pulmonary venous anomalies and six had nodular lesions on CT...

OBJECTIVE: The purpose of this study is to compare diagnostic reference levels from a local European CT dose registry, using radiation-tracking software from a large patient sample, with preexisting European and North American diagnostic reference levels. MATERIALS AND METHODS: Data (n = 43,761 CT scans obtained over the course of 2 years) for the European local CT dose registry were obtained from eight CT scanners at six institutions. Means, medians, and interquartile ranges of volumetric CT dose index (CTDIvol), dose-length product (DLP), size-specific dose estimate, and effective dose values for CT examinations of the head, paranasal sinuses, thorax, pulmonary angiogram, abdomen-pelvis, renal-colic, thorax-abdomen-pelvis, and thoracoabdominal angiogram were obtained using radiation-tracking software...

BACKGROUND: Our objective was to quantify variability across the UK in the management of a complex abdominal aortic aneurysm (AAA). METHODS: An online survey was emailed to all members of the Vascular Society for Great Britain and Ireland. The survey presented a vignette of a 63-year-old woman with significant respiratory co-morbidity whose computed tomographic (CT) angiogram demonstrated a 54 mm AAA with a short (7 mm) proximal neck but no other adverse morphological features for a standard or complex endovascular aneurysm repair (EVAR)...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

INTRODUCTION: We present an interesting case of a 55 year-old male with a large left chest mass after significant cutaneous bleeding. CT angiogram of the chest revealed arteriovenous malformation with blood supply from subbranches of the left subclavian artery, left internal mammary artery and left external carotid artery. Measuring 5.0x14.0x10.8cm, the mass extended superior to the clavicle and inferior to the third rib with medial and lateral borders at the level of the clavicular head and coracoid, respectively...

OBJECTIVE: High-pitch protocols are increasingly used in cardiovascular CT assessment for transcatheter aortic valve implantation (TAVI), but the impact on diagnostic image quality is not known. METHODS: We reviewed 95 consecutive TAVI studies: 44 (46%) high-pitch and 51 (54%) standard-pitch. Single high-pitch scans were performed regardless of heart rate. For standard-pitch acquisitions, a separate CT-aortogram and CT-coronary angiogram were performed with prospective gating, unless heart rate was ≥70 beats/min, when retrospective gating was used...

BACKGROUND: Anaphylaxis is an acute, potentially fatal medical emergency. Myocardial injury or infarction in the setting of an anaphylaxis can be due the anaphylaxis itself, when it is known as Kounis syndrome or it can also be due to the effect of epinephrine treatment. Epinephrine is considered as the cornerstone in management of anaphylaxis. Myocardial infarction secondary to therapeutic doses of adrenaline is a rare occurrence and only a few cases have been reported in literature...

An 86-year-old woman presented to hospital with melaena. This was her third presentation with the same symptom. There was no obvious source of bleeding on her oesophagogastroduodenoscopy; however, it did show a previously clipped Dieulafoy lesion. CT angiography showed an aneurysm arising from the hepatic artery. Selective coeliac artery angiogram showed aneurysmal dilatation of the distal part of the coeliac trunk and confirmed the presence of the common hepatic artery aneurysm. The aneurysm was coiled by the interventional radiologist...

Unilateral absent right pulmonary artery is a rare developmental anomaly that usually presents in late childhood and adolescence as recurrent respiratory tract infections, dyspnoea and haemoptysis. We report a case of a 2-day-old baby with respiratory distress and differential cyanosis. Echocardiogram showed pulmonary hypertension with absent right pulmonary artery. The findings were confirmed by CT angiogram. The baby improved with pulmonary vasodilators and antifailure medications.
