Knowledge of the variations in renal vascular anatomy is important before laparoscopic donor or partial nephrectomy and vascular reconstruction for renal artery stenosis or abdominal aortic aneurysm. Recently, multidetector computed tomographic (MDCT) angiography has become a principal imaging investigation for assessment of the renal vasculature and has challenged the role of conventional angiography. It is an excellent imaging technique because it is a fast and non-invasive tool that provides highly accurate and detailed evaluation of normal renal vascular anatomy and variants. The number, size and course of the renal arteries and veins are easily identified by MDCT angiography. The purpose of this pictorial essay is to illustrate MDCT angiographic appearance of normal anatomy and common variants of the renal vasculature.

A 40 year old man who had hydatid cysts in his liver and right kidney was found to have complete heart block during preoperative evaluation and was referred to our clinic. Blood pressure was 120/80 mm Hg and the heart rate was 40/min and regular. The physical examination was normal except for hepatomegaly which reached almost 15 cm at the midclavicular line. The electrocardiogram showed complete atrioventricular block with a ventricular rate between 35 and 40 beats per minute. He had a white cell count of 12 100/mm3 and 13-2% eosinophilia on the peripheral blood smear.

Öz2019 yeni koronavirüs hastalığı , tüm dünyaya yayılan önemli bir halk sağlığı sorunudur. Tanıda altın standart realtime reverse transcription polymerase chain reaction (RT-PCR) testi olsa da, özellikle klinik semptomu olup testin negatif geldiği hastalarda toraks bilgisayarlı tomogra (BT) önemli bir yol göstericidir. Bu derlemenin amacı, COVID-19'un tanısında giderek daha fazla kullanılan toraks BT' de saptanan bulguları özetlemektir.

AIMTo comparatively evaluate Seldinger and Trocar techniques in the percutaneous treatment of hydatid disease.METHODSTrocar and Seldinger techniques were used for 49 and 56 cysts, respectively, among 106 hydatid cysts in 88 patients. The number of males and females were 22 and 66, respectively with a mean age of 44.9 years (range, 15-87). Follow-up studies included cyst diameter, cyst contents, and morphological changes in the cyst wall, local recurrence, and secondary invasion, using ultrasound, computerized tomography and chest X-rays.RESULTSThe positive criteria of healing were a decrease in cyst diameter, progressive solidification of the cyst contents, and disappearance of the cyst. Local recurrence was defined as an increase in the cyst diameter and contents, and appearance of daughter cysts in the primary cavity, while secondary dissemination was defined as the appearance of new cysts outside the treated cyst. Mean duration of follow-up was 19.23 mo (range, 18-26 mo). Follow-up results demonstrated that no significant differences were present between the Trocar and Seldinger techniques in the percentage of decrease in the cyst volume, rate of early complications, local recurrence and secondary dissemination (P = 0.384, 0.069, 0.215 and 0.533, respectively).CONCLUSIONThere are no differences between the Seldinger and Trocar techniques that gain entry to the cyst cavity in terms of the efficacy of the treatment and the rates of early and late complications.
