This study aims to determine the radiation doses of patients and staff during different interventional radiology and cardiology examinations. Dose measurements for interventional radiology examinations were performed in Ibn-i Sina Hospital of Ankara University using Siemens Artis-Zee medical imaging system. Patient dose measurement was carried out for interventional cardiology examinations in Cardiology Department of TOBB-ETU University, Medical Faculty Hospital using Philips Allura Centron interventional X-ray system.

Involvement of the renal artery is common in Takayasu arteritis. We, herein, present on a patient with Takayasu arteritis causing severe renal failure and a successful auto-transplantation. This case shows that early diagnosis and immediate appropriate interventions are life-saving in patients with Takayasu arteritis.

Materials And Methods: Between July 2012 and August 2013, 41 patients with acute or subacute DVT underwent PMT. The Cleaner thrombectomy device was used in a single-session technique for patients with lower-extremity DVT.
Magnetic resonance angiography and digital substraction angiography (DSA) findings in a case with a rare congenital thoracoabdominal aortic hypoplasia and common celiamesenteric trunk variation with occlusion of infrarenal abdominal aorta are described here. To our knowledge, this aortic anomaly has not been previously described in the English literature. DSA is the optimum imaging modality for determination of aortic hypoplasia, associated vascular malformations, collateral vessels, and direction of flow within vessels.

Materials And Methods: Tunneled catheters were placed in 75 bone marrow transplant patients with fluoroscopic guidance. The left subclavian vein was used in 67 patients, whereas the right side was used in 9.
Background: The increased tendency to thromboembolism in cancer patient has been recognized for a long time. However, arterial thromboembolism and thrombosis of the pulinonary artery have rarely been reported. Pulmonary thromboembolism is usually a complication of peripheral venous thrombosis.

Materials And Methods: Nineteen cases with the diagnoses of end-stage renal disease with multiple hemodialysis catheter access were examined. Direct contrast-enhanced 3D MR venograms were obtained with 1.

Budd-Chiari Syndrome is one of the several causes of portal hypertension and is characterised by hepatomegaly, ascites and abdominal pain. The treatment requires either medical or interventional/surgical procedures. A case of Budd-Chiari Syndrome with a membranous web that causes obstruction in the ostium of the inferior right hepatic vein is reported here which was treated by percutaneous transluminal angioplasty (PTA).

Effective doses for each measurement technique were estimated using the conversion factors that have been determined for specific X-ray views in a mathematical phantom. Exposure conditions used in clinical practice never match these theoretical models exactly, and deviations from the assumed standard conditions cause uncertainties in effective dose estimations.

The gray-scale ultrasonographic appearances of dilated intrarenal vascular structures may mimic peripelvic cysts or hydronephrosis. We report a patient with portal hypertension in whom color Doppler ultrasound was found to be a very practical imaging technique in demonstrating varices of the renal segmental veins.

Twelve animals received fresh, unheparinized arterial blood via three injections (15 ml total) into the cisterna magna. Selective vertebral arteriography was performed on Day 0, and blood injections were performed on the second and third days after the first injection.

The diagnosis of fibromuscular dysplasia was established by selective renal angiography, and percutaneous transluminal renal angioplasty was performed. After successful dilation, the blood pressure returned to normal.
