Radiofrequency Thermoablation

Radiofrequency ablation (RFA) is an effective minimally invasive treatment for nonsurgical hepatocellular carcinoma (HCC), but ablation of tumors close to the gallbladder could be associated with several complications. We report our experience on the treatment of HCC close to the gallbladder with RFA. Eight RFA procedures were performed in eight patients with HCC larger than 3 cm and less than 5 cm close to the gallbladder. In all cases, a percutaneous approach was used. There were no major complications. Only in two patients a minimal wall thickening of the gallbladder was observed. Contrast enhanced computed tomography carried out after 30 days from the first procedure showed complete necrosis in seven patients (87%). Only one patient had local recurrence at 11 months of followup. Although limited, our experience suggests that, after careful preprocedural planning, in experienced hands and with appropriate technology, percutaneous RFA could be safely performed even for lesions larger than 3 cm located in close adjacency to the gallbladder.

Carcinoid tumors are neuroendocrine tumours, the most common tumour of the small bowel and its incidence is rising. Most carcinoid tumours grow slowly and mostly asymptomatic or may present with nonspecic abdominal pain or carcinoid syndrome. We had a 38 year old, female patient presented with generalized, intermittent, dull aching abdominal pain accompanied with distension and obstipation for 2 days with associated vomiting. She complained of weight loss and constipation during this period. On examination abdomen showed deep tenderness in periumbilical, right lower quadrant regions. No guarding, rigidity, mass or free uid. On per-rectal examination, there was no tenderness and the rectum was empty. Contrast enhanced computed tomography scan showed enhancing polypoidal lesion noted in distal ileum causing proximal dilatation of small bowel with air uid levels and circumferential wall thickening in dilated ileum proximal to polypoidal lesion, strongly enhancing nodal mass with specs of calcication, multiple mesentric lymph nodes and no liver metastasis. As the conservative management for 48 hours showed no improvement in symptoms, an emergency exploratory laparotomy was performed, and an intraluminal mass was identied from ileocecal junction causing obstruction with dilated loops of ileum and jejunum. Local resection of terminal ileum was performed and a side to side anastomoses was done using GI stapler. Histopathology showed diagnosis of neuroendocrine tumor

Endovascular repair of pregnancy-associated aortic disease is controversial because the long-term result is still unclear. We report a rare case of early postpartum spontaneous aortic rupture that was successfully treated by endovascular repair, with a good midterm result. Multiangle thin-slice images of contrast-enhanced computed tomography revealed a very small rupture point. It was successfully repaired by minimally invasive treatment.

Abstract Funding Acknowledgements Type of funding sources: None. Background The natural history of thoracic aortic aneurysm (TAA) is one of progressive expansion. Asymptomatic patients who do not meet criteria for repair require conservative management including ongoing aneurysm surveillance, mostly carried out by contrast-enhanced computed tomography angiography (CTA). Purpose To prospectively compare image quality and reliability of a prototype non-contrast, self-navigated 3D whole-heart magnetic resonance angiography (MRA) with contrast-enhanced computed tomography angiography (CTA) for sizing of thoracic aortic aneurysm (TAA). Methods Self-navigated 3D whole-heart 1.5 T MRA was performed in 20 patients (aged 67 ± 8.6 years, 75% male) for sizing of TAA; a subgroup of 18 (90%) patients underwent additional contrast-enhanced CTA on the same day. Subjective image quality was scored according to a 4-point Likert scale and ratings between observers were compared by Cohen’s Kappa statistics. Continuous MRA and CTA measurements were analyzed with regression and Bland-Altman analysis. Results Overall subjective image quality as rated by two observers was 1 [interquartile range (IQR) 1-2] for self-navigated MRA and 1.5 [IQR 1-2] for CTA (p = 0.717). For MRA a perfect inter-observer agreement was found for presence of artefacts and subjective image sharpness (κ=1). Subjective signal inhomogeneity correlated highly with objectively quantified inhomogeneity of the blood pool signal (r = 0.78-0.824, all p <0.0001). Maximum diameters of TAA as measured by self-navigated MRA and CTA showed excellent correlation (r = 0.997, p < 0.0001) without significant inter-method bias (bias -0.0278, lower and upper limit of agreement -0.74 and 0.68, p = 0.749). Inter- and intraobserver correlation of aortic aneurysm as measured by MRA was excellent (r = 0.963 and 0.967, respectively) without significant bias (all p ≤ 0.05). Conclusion Self-navigated 3D whole-heart MRA enables reliable contrast- and radiation free aortic dilation surveillance without significant difference to standardized CTA while providing predictable acquisition time and by offering excellent image quality.
