    Balloon Dilatation of Iatrogenic Ureteral Strictures after Upper Urinary Tract Reconstruction
    (2015) Duman, Enes; Yildirim, Erkan; Akillioglu, Ishak; Yucesan, Selcuk
    Purpose: Open pyeloplasty is the gold standard treatment of uretero-pelvic junction (UPJ) stenosis. Although failure after open pyeloplasty or uretero-neosistosmy is not common, percutaneous or endoscopic interventions must be necessary in some cases. We present treatment of 6 pediatric patients by balloon dilatation after failed surgery. Material and Methods: Between 2008 and 2013 6 children were treated. Five patients had undergone open pyeloplasty for UP stenosis and, one has uretero-vesical anastomosis stricture after ureteroneosistostomy. Percutaneous antegrade balloon dilatation and double J stent placement were performed in three of six patients. In the other three patients retrograde endoscopic balloon dilatation and double J stent placement were performed. Results: Primary technical success was %50 and %100 for antegrade and retrograde approach respectively. Antegrade approach has failed in 3 patients (%50) and, retrograde approach and treatment were successful in all of these patients. Secondary and tertiary balloon dilatations were done through antegrade approach in 3 patients. Mean duration of double J stent was 114 days. As of today, five patients are followed smoothly. One patient who has UP stenosis underwent secondary open surgery. Conclusion: Balloon dilatation can be used safely in both antegrade and retrograde approaches because of lower profile of balloon catheters, so it could be considered as a first line treatment option after failed surgical treatment of upper urinary tract stenosis in children.

    Association between treatment with coil embolization of renal artery aneurysm and resistant hypertension
    (2016) Duman, Enes; Yildirim, Erkan; Ciftci, Ozgur; Cifci, Egemen
    Hypertension is the number one risk factor in preventable causes of death in the world. Resistant hypertension is defined as blood pressure that remains uncontrolled despite at least three antihypertensive medications including a diuretic. Treatment of hypertension includes many modalities from lifestyle changing to multiple drug using, angioplasty. In this case report, we aim to emphasize the effects of renal artery aneurysm treatment on resistant hypertension.

    Percutaneous Placement of Pancreatico-biliary Drainage Catheter for the Treatment of Complicated Pancreatic Anastomotic Leakage: an Alternative Treatment Option
    (2016) Duman, Enes; Yildirim, Erkan; 0000-0002-9057-722X; 27994344; ABI-3856-2020
    A 58-year-old female patient who had anastomotic leakage after a Whipple operation was treated with a percutaneously placed pancreatico-biliary drainage catheter. Complete secondary healing of the anastomotic defect and leakage was seen on control cholangiography examination on the 35th postoperative day, and the pancreatico-biliary drainage catheter was removed. She was discharged on the 39th postoperative day uneventfully. Percutaneous pancreatico-biliary drainage should be kept in mind as an alternative treatment option of complicated pancreatic anastomotic leakage after a Whipple operation.

    Epileptic Seizures Induced by a Spontaneous Carotid Cavernous Fistula
    (2016) Celik, Guner Koyuncu; Yildirim, Erkan; 0000-0002-9057-722X; 0000-0002-2477-3660; 28077946; ABI-3856-2020
    A 79-year-old woman was admitted to our emergency department with complaints of fainting and loss of consciousness three times during the past month. She was diagnosed with epilepsy and started to be treated with antiepileptic drug. Physical examination showed, in the left eye, chemosis, limited eye movements in all directions, and minimal exophthalmos as unexisting symptoms on admission developed on the sixth day. Orbital magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) imaging revealed a carotid cavernous fistula (CCF). Epileptic attacks and ophthalmic findings previously present but diagnosed during our examinations were determined to ameliorate completely after performing the coil embolization. Based on literature, we present the first case with nontraumatic CCF manifesting with epileptic seizures and intermittent eye symptoms in the present report.
