    Background and purpose: The purpose of this study is to investigate the relationship between Rosenthal basal vein (BVR) type and diameter and perimesencephalic nonaneurysmal subarachnoid hemorrhage (P-SAH). Materials and methods: Aneurysmal subarachnoid hemorrhage (A-SAH), P-SAH, and control groups were evaluated, and BVRs were classified by type. BVR diameters in patients were measured. Results: There was a statistically significant difference of BVR drainage types between groups (P=.002). BVR diameters of patients with normal drainage pattern in P-SAH group were significantly smaller than those in both other groups (P<.001). Conclusion: There is a relationship between P-SAH and BVR primitive drainage type. P-SAH risk increases in parallel with decreasing caliber of BVR in patients with normal drainage pattern.

    Uzun süreli hemodiyalizde transhepatik santral venöz kateterizasyon
    (Ortadoğu Yayınevi, 2012-08) Erdoğan, Cüneyt; Aktaş, Nimet; Duşak, Abdurrahim; Şenkaya, Işık; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Nefroloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Kalp Damar Cerrahisi Anabilim Dalı.; A-7826-2019; 8293835700; 55134803100; 6507393726; 6603498369
    Objective: Retrospective analysis of hemodialysis catheters implanted using transhepatic venous route in terms of safety and functionality in patients with exhausted conventional venous access routes. Material and Methods: Ten patients underwent placement of 22 transhepatic 14F tunneled hemodialysis catheters at our center in the period 2007-2011. Catheter safety was assessed by means of complications encountered. Catheter functionality was assessed by means of the data derived from the electronic documents and digital images captured during the device problems and catheter revisions. Catheter patency was described using Kaplan-Meier survival curve. Results: Technical success was achieved in all patients. There was no hepatic injury or bleeding related to the procedure. Catheter functionality was impared due to the complications such as thrombosis, migration and infection. The catheter thrombosis rate was 0.18, the catheter migration rate was 0.12, and catheter-related infection rate was 0.08 per 100 catheter-days. Mean device patency was 132 (28-214) catheter days. Fifty percent of the catheters functioned longer than 182 catheter days. Mean catheter stay in-situ was 283 (20-629) catheter days. Mean single access patency was 217 (20-571) catheter days. Conclusion: By using transhepatic venous route, effective and safe hemodialysis can be performed in long term in patients with limited venous access.
