    Investigation of proper hepatic artery and gastroduodenal artery variations by multidetector computed tomography angiography method
    (Taylor & Francis Ltd, 2020) Ekingen, Arzu; Tuncer, Mehmet Cudi; Ertugrul, Ozgur
    Purpose: The purpose of this study is to evaluate the clinical anatomic variations of the proper hepatic artery (PHA) and the gastroduodenal artery (GDA). For this purpose, angiographic images of patients were evaluated. Materials and methods: We retrospectively reviewed the multiple-detector computed tomography angiography images of 671 patients. Results: In this retrospective study, 35 different types were identified as associated with PHA and GDA. There were 292 patients (43.52%; 175 females and 117 males) included in normal anatomical classification. Different anatomic variations were detected in 300 patients (44.71%; 129 females and 171 males). In 79 patients, arterial branch follow-up failed. These patients were evaluated as an unidentified group. Conclusion: We described different vascular variations in the PHAs and GDAs of our patients.

    Spontaneous Rupture of a Hepatic Hydatid Cyst Perforating into the Gastric Antrum Diagnosed with Magnetic Resonance Imaging A Case Report and Review of the Literature
    (Sci Printers & Publ Inc, 2021) Ertugrul, Ozgur; Tuncer, Mehmet Cudi; Gedik, Ercan
    BACKGROUND: Hepatic hydatid disease is a parasitic zoonosis caused by Echinococcus granulosus. The liver is the most frequently parasitized organ in humans. E. granulosus typically forms a small, fibrous, edged cyst when there is any surrounding host reaction. Classically, there is a large parental cyst with a large number of peripheral daughter cysts. Satellite daughter cysts are common. E. granulosus has two forms: pastoral and sylvatic. CASE: A 36-year-old woman was hospitalized upon complaint of nonspecific, continuous, moderate-to-severe epigastric pain of 1 week's duration. There was no fever or vomiting. Only serum aspartate transaminase (420 U/L), alanine aminotransferase (180 U/L) (normal up to 50 U/L), and erythrocyte sedimentation rate (65 mm/hour) were increased in her laboratory findings. She had a hydatid cyst in the right lobe of the liver and refused all treatment protocols. Her magnetic resonance imaging and magnetic resonance cholangiopancreatography data showed a ruptured liver hydatid cyst associated with closed perforation in the antrum region of the stomach. CONCLUSION: Typically, locations of hepatic hydatid cyst can be seen into the biliary tree, peritoneal space, and blood stream, but extension outside of the liver is rarely seen in the literature.

    Variations in the vascular and biliary structures of the liver: a comprehensive anatomical study
    (Acta Medical Belgica, 2018) Ulger, Burak Veli; Hatipoglu, Eyup Savas; Ertugrul, Ozgur; Tuncer, Mehmet Cudi; Ozmen, Cihan Akgul; Gul, Mesut
    Purpose: Vascular structures of the liver and the bile ducts are crucial during liver transplantation or liver resection surgery. Here, we report on variations in the vascular structures and bile ducts of 200 patients. Materials and Methods: We reviewed magnetic resonance cholangiopancreatographic and multiple-detector computed tomographic data. Results: Michels type 1 was detected in 54% of the patients. The other most common variations were, respectively, Michels type 5 (13%) and type 2 (11%). Unclassified variations were defined as Michels type 11; 5% of patients were in this group. Type 1 variations in the hepatic portal vein were detected in 76% of our study group. Other common variations were type 2 (9%) and type 3 (8.5%). The left and intermediate hepatic veins united to become a single vein and then joined the inferior vena cava in 64% of the patients. The right, intermediate, and left hepatic veins joined the inferior vena cava separately in 36% of the patients. Type A, which represents the classic anatomy of the bile duct, was observed in 51.5% of our patients. Type C1 and type B were detected in 15% and 12% of patients, respectively. Conclusions: We describe vascular and biliary variations in the livers of our patients.
