Single step therapy for abscess foci localized at different parts of the body using trocar type catheter: Results of two year-experience

Objectives: The aim of this study was to emphasize the feasibility and cost effectiveness of trocar type catheter in percutaneous abscess drainage under imaging guidance and to determine the clinical efficacy of the method.Materials and methods: From June 2008 to December 2010, 48 patients who were referred to interventional radiology unit, in order to undergo percutaneous abscess drainage. All was data including age, the organ or the part of the body where the abscess was localized and size of abscess were recorded. Forty-two (87%) patients underwent drainage with ultrasonographic guidance, while 6 (13%) underwent with computed tomography guidance. One pediatric patient underwent systemic sedation anesthesia (with remiphentanyl and midazolam) and the rest of the patient with local anesthesia (with prilocain hydrochlorid). Catheterization procedure with which abscess drainage was done accepted as technically successful.Results: Imaging guided percutaneous abscess drainage procedures were performed with trocar type catheter to localized abscesses in different organs or systems in 48 patients (25 men, 23 women, mean age 52 years, range 2-82 years). Technical success was 100% in all cases. No patient had a complication during the procedure. Time to extraction of percutaneous catheter after drainage procedure was 5-28 days (mean 11.2 days). There was no recurrence except for a case, in which an abscess at the splenectomy site was successfully drained.Conclusion: Percutaneous drainage with imaging guidance using the trocar type catheter should be preferred because of its feasibility, cost-effectiveness, and reduced rate of complications in treating abscesses, which localized at different organ systems

Hepatosellüler karsinomda radyolojik algoritma ve görüntüleme yöntemleri

Radyolojik görüntülemenin amacı hepatosellüler karsinomu erken evrede tespit etmektir. Bunun amacı lezyonu küratif tedavi evre- sinde yakalayabilmektir. Son yıllarda özellikle küçük karsinomların erken tespit edilebilmesi için fazlaca çaba sarf edilmektedir. Bu derlemenin amacı hepatosellüler karsinomların tespiti ve tanımlanmasında ultrasonografi, bilgisayarlı tomografi, manyetik rezonans görüntüleme, radyonüklid görüntüleme, pozitron emisyon tomografi ve dijital subtraksiyon anjiografi gibi invaziv olmayan görüntü- leme yöntemlerinin etkinliğini belirlemekti

In recent years, there have been many efforts to improve early detection of small HCC. The purpose of this review is to describe the pertinent findings of HCCs in non-invasive, diagnostic imaging, including ultrasound, computed tomography, magnetic resonance, radionuclide scanning, positron emission tomography and digital subtraction angiography imaging techniques

Persistan hiperplastik primer vitreus

Persistent hyperplastic primary vitreous (PHPV) is a disorder of ocular development which occurs due to incomplete regression of the embryonic vitreous and hyaloid vasculature. Most cases of PHPV are sporadic and unilateral. We report a case of PHPV in a 5-year-old male who presented with complaint of decreasing eye size. Grey-scale ultrasonography (US) evaluation revealed an hypoechogenic band in the posterior segment of the left globe extending from the posterior surface of the lens capsule to the optic disc. Also magnetic resonance imaging (MRI) findings suggested the diagnosis of persistent hyperplastic primary vitreous.Persistan hiperplastik primer vitreus (PHPV) embriyonik vitreusun inkomplet regresyonuna bağlı olarak ortaya çıkan gelişimsel oküler bir hastalıktır. PHPV vakalarının birçoğu sporadiktir ve tek taraflı görülür. Bu yazıda gözde küçülme şikayeti ile başvuran 5 yaşındaki PHPV olgusu sunuldu. Ultrasonografi (USG) incelemesinde sol glob posterior segmentinde, lens posteriorundan optik diske uzanan hipoekoik bant görüldü. Aynı zamanda magnetik rezonans görüntüleme (MRG) bulguları da PHPV tanısını destekledi
