Öğe Acromesomelic-Spondyloepiphyseal Dysplasia Associated With Congenital Optic Atrophy - Report of a Family(Springer Verlag, 1993) Sener, Rn; Ustun, Ee; Özkınay, Cihangir; Memis, A; Oyar, OWe report a family with a unique combination of radiological manifestations of acromesomelic dysplasia and spondyloepiphyseal dysplasia in two members (a man and his daughter) associated with congenital optic atrophy in four generations. The inheritance pattern of this complex anomaly appeared to be autosomal dominant.Öğe Angiographic findings and endovascular interventional procedures in 41 patients with Takayasu's arteritis(B M J Publishing Group, 2004) Aksu, K; Keser, G; Memis, A; Inal, V; Parildar, M; Doganavsargil, EÖğe Angiographic findings and endovascular interventional procedures in 41 patients with Takayasu's arteritis(B M J Publishing Group, 2004) Aksu, K; Keser, G; Memis, A; Inal, V; Parildar, M; Doganavsargil, EÖğe Aortic origin of right hepatic artery and superior mesenteric origin of splenic artery: two rare variations demonstrated angiographically(Springer-Verlag, 2001) Oran, I; Yesildag, A; Memis, AAnatomical variations of the celiac trunk and superior mesenteric artery are not infrequent. Knowledge of the existing aberrations is important in planning and conducting surgical of radiological procedures. A case of right hepatic artery arising independently from the aorta supplying an hepatocellular carcinoma was identified, through which transarterial chemoembolization was successfully performed. A second case is presented with a common splenomesenteric trunk branching into the splenic and superior mesenteric arteries. These two cases represent exceptional arterial variations in the upper abdomen.Öğe Bilateral Breast Involvement In Acute Lymphoblastic-Leukemia - Color Doppler Sonography Findings(Amer Roentgen Ray Soc, 1995) Memis, A; Killi, R; Orguc, S; Ustun, EeÖğe Biliary complications following adult-to-adult living donor liver transplantation(Elsevier Science Bv, 2002) Karasu, Z; Tokat, Y; Memis, A; Ersoz, G; Yuzer, Y; Killi, R; Akarca, U; Gunsar, F; Batur, YÖğe Biliary reconstructions and complications encountered in 50 consecutive right-lobe living donor liver transplantations(Wiley, 2003) Icoz, G; Kilic, M; Zeytunlu, M; Celebi, A; Ersoz, G; Killi, R; Memis, A; Karasu, Z; Yuzer, Y; Tokat, YBiliary complications appear to be the leading cause of postoperative complications after living donor liver transplantation (LDLT). The aim of this study is to analyze the complications, treatment modalities, and outcomes of biliary anastomoses in a series of 50 consecutive right-lobe LDLTs. Median patient age was 45 years, and median right-lobe graft volume was 740 g. Graft-recipient weight ratio was 0.69 to 1.80. Median follow-up time was 15 months (range, 2 to 38 months). Eleven of 50 patients died, resulting in an overall allograft and patient survival rate of 78%. In biliary reconstruction, a duct-to-duct (D-D) anastomosis or a standard Roux-en-Y (R-Y) anastomosis was performed. Twenty-nine grafts (58%) had a single duct for anastomosis. Seventeen grafts (34%) had two bile duct orifices, and four grafts (8%) had three bile duct orifices. A D-D anastomosis was performed in 36 cases (72%), whereas R-Y reconstruction was preferred in 14 cases (28%). The overall incidence of biliary anastomotic complications was 30% in this series. Five patients developed biliary leaks, presumably from the cut surface, and all of them healed spontaneously. Two bilomas were drained percutaneously. Anastomotic strictures occurred in 8 patients (16%) and were significantly greater than in the R-Y group (P =.03). Although strictures seemed to develop more frequently in allografts with multiple bile ducts, this did not reach statistical significance (P =.05). All strictures were managed by nonsurgical measures initially. Restenosis occurred in 2 patients, both of whom had an R-Y anastomotic stricture. These anastomoses were revised surgically, giving a reoperation rate of 4% for biliary problems. No graft or patient was lost because of biliary problems. Our data suggest that D-D anastomosis is a safe and feasible method of biliary reconstruction in LDLT by preserving physiological bilioenteric continuity and allowing easy access through endoscopic techniques.Öğe Biliary reconstructions and complications encountered in 50 consecutive right-lobe living donor liver transplantations(Wiley, 2003) Icoz, G; Kilic, M; Zeytunlu, M; Celebi, A; Ersoz, G; Killi, R; Memis, A; Karasu, Z; Yuzer, Y; Tokat, YBiliary complications appear to be the leading cause of postoperative complications after living donor liver transplantation (LDLT).

We report a unique case of an endometrial stromal sarcoma metastasizing to the breast after a 17-year-period. Mammographic and ultrasonographic findings with histopathological correlation are described.Öğe Carotid steal: Report of ten cases(Amer Inst Ultrasound Medicine, 1998) Ozbek, SS; Memis, A; Killi, R; Pourbagher, MA; Demirpolat, G; Oran, I; Pourbagher, AThe blood flow may be diverted from the external to the internal carotid artery via the carotid bulb in the absence of flow in the common carotid artery. We aimed to investigate the prevalence, hemodynamics, and clinical features of this condition. Reviewing the records of color duplex ultrasonographic examinations, we found carotid steal in 12 carotid arteries of 10 patients. In three patients flow in the ipsilateral external carotid artery was bidirectional. The steal had been demonstrated angiographically in six patients. The cause of the phenomenon was atherosclerosis, Takayasu arteritis, or trauma. Awareness of this pathway of collateral circulation may contribute to diagnostic work-up and expand management alternatives.Öğe Case-Report 717 - Osteodysplasty (Melnick-Needles Syndrome)(Springer Verlag, 1992) Memis, A; Ustun, Ee; Sener, RnÖğe Catheter and MR angiography of persistent trigeminal artery associated with occipital arteriovenous malformation(Pergamon-Elsevier Science Ltd, 2000) Oran, I; Parildar, M; Memis, A; Yunten, NWe present a patient with an occipital arteriovenous malformation fed by the posterior cerebral artery coexisting with an ipsilateral persistent trigeminal artery. These anomalies were well demonstrated by MR angiography and confirmed by catheter angiography. (C) 2000 Elsevier Science Ltd.

In this report two cases of clear cell chondrosarcomas with atypical radiologic appearances are presented. The findings of X-ray films and MRI are described with histologic correlation. In the first case the lesion showed a very expansile and long segment involvement of the humerus. In the second case the lesion was located in the diaphysis of the femur causing a large cortical destruction.Öğe Ct of Schizencephaly(Amer Roentgen Ray Soc, 1992) Sener, Rn; Bilgin, G; Memis, AÖğe Early breast cancer: radiological diagnosis(Medimond S R L, 1999) Memis, A; Antypas, GÖğe Effect of endovascular treatment on nitric oxide and renal function in Takayasu's arteritis with renovascular hypertension(Karger, 2002) Parildar, Z; Gulter, C; Parildar, M; Oran, I; Erdener, D; Memis, ABackground: Renal involvement in Takayasu's arteritis (TA) effects the disease outcome and endovascular treatment is an effective treatment of choice. We investigated nitric oxide (NO) levels and the effect of endovascular treatment in renovascular hypertensive TA patients. Methods: In five hypertensive patients with renal artery stenosis due to TA, serum creatinine, nitrite, nitrate; urinary microalbumin, nitrite, nitrate measurements and blood pressures were recorded at entry and after 24 h and 6 weeks of endovascular treatment. Results: Serum NO levels were higher in patients than controls (p = 0.008). Serum and urine NO levels increased 24 h after the treatment and decreased after 6 weeks (p = 0.015; p = 0.01, respectively). After the treatment blood pressures decreased. Urinary microalbumin excretions increased after the intervention (p = 0.02) and returned to normal in patients 1 and 4, and decreased in the other:. There were no significant differences in estimated glomerular filtration rate (EGFR), serum creatinine, urinary sodium and potassium levels. Conclusion: Increased NO secretion in these patients may contribute to improve the prognosis of renal function through its vasodilator and antiproliferative activities possibly by counterbalancing the excessive vasoconstrictor actions. Endovascular treatment causes a dilatation-induced shear stress that may be responsible for the increased NO release, which in turn leads to the rapid hypotensive response. Copyright (C) 2002 S.

Methods: Over the past 7 years, 20 patients were treated by transcatheter embolization in the same sitting with diagnostic angiography. Four right hepatic, one cystic, two gastroduodenal, one cavernosal artery, three superior mesenteric artery branch, and 11 renal artery branch pseudoaneurysms were included in the study. Results: Surgery was completely avoided in 19 patients. In the remaining patient with a superior mesenteric artery branch pseudoaneurysm, endovascular embolization was unsuccessful. Eighteen pseudoaneurysms were thrombosed with coil embolization alone. The remaining three pseudoaneurysms needed NBCA embolization. Two patients died from sepsis within 5 weeks after embolization. Conclusion: Emergent diagnosis and treatment are essential in visceral artery pseudoaneurysms because of the high rate of death, Transcatheter embolization with platinum coils is an efficient, safe treatment of choice. NBCA may be used to avoid proximal embolization of the visceral arteries that could not be catheterized selectively because of tortuosity, vessel size, or anatomic location.Öğe Embolization of visceral pseudoaneurysms with platinum coils and N-butyl cyanoacrylate(Springer-Verlag, 2003) Parildar, M; Oran, I; Memis, ABackground: We evaluated the efficacy of transcatheter embolization in visceral artery pseudoaneurysms with platinum coils and N-butyl-cyano-acrylate (NBCA).
