    (Turkish Neurosurgical Soc, 2018) Aydin, Elcin; Gok, Mustafa; Esenkaya, Asim; Cinar, Celal; Oran, Ismail
    AIM: To evaluate iatrogenic vascular injuries in the craniocervical region and their endovascular management. MATERIAL AND METHODS: Twenty-one patients (9 women, 12 men) with a mean age of 53.6 years (range 16-87 years), who underwent endovascular embolization for iatrogenic vascular injury in the craniocervical region between December 2000 and October 2015, were included in this retrospective study. Types of iatrogenic injuries, etiologies that caused these injuries and details of endovascular managements were reported. RESULTS: The etiologies of the vascular injuries were as follows: transsphenoidal surgery (n=9), skull-base surgery (n=2), cholesteatoma surgery (n=1), tracheostomy (n=2), central venous catheterization (n=2), oropharyngeal tumor operation (n=1), endovascular treatment of internal carotid artery (ICA) stenosis (n=1), suprasellar epidermoid tumor operation (n=1), sphenoid sinus tumor surgery (n=1), and speech prosthesis device placement (n=1). The types of vascular injuries diagnosed at the time of angiography were; 2 occlusions, 2 stenoses, 2 dissections, 1 carotid cavernous fistula, 8 artery rupture with extravasation, and 9 pseudoaneurysms. Endovascular management of these vascular injuries were; parent artery occlusion (PAO) (n=15), aneurysm occlusion (n=3), covered stent (n=1) and conservative management (n=2). All patients except two were successfully treated. No patient had bleeding within a 30-day period after angiography. Long-term follow-up was available in all patients without occurrence of re-bleeding. One patient died due to complications related to primary vascular injury. CONCLUSION: Although iatrogenic vascular injuries are rare, early diagnosis and management may be lifesaving. Endovascular techniques are reliable and safe in most of the patients.

    Endovascular treatment of intracranial infectious aneurysms
    (Springer, 2016) Esenkaya, Asim; Duzgun, Fatih; Cinar, Celal; Bozkaya, Halil; Eraslan, Cenk; Ozgiray, Erkin; Oran, Ismail
    Intracranial infectious aneurysm (IIA) accounts for less than 5 % of all intracranial aneurysms. The aim of this study was to evaluate the role of endovascular treatment for IIA. During a 14-year period, 15 patients (age range, 2-68 years; mean, 42.8 years) with 17 aneurysms were diagnosed with IIA and treated via an endovascular route at our institution. The IIA diagnosis was based on clinical and laboratory findings of infection, echocardiography results, and digital subtraction angiography that were collected retrospectively. All patients were clinically and radiologically followed. The modified Rankin scale was used to evaluate clinical outcome. Among 15 patients, 12 presented with ruptured aneurysms (7 intraparenchymal hematoma, 4 subarachnoid hemorrhage, 1 subdural hematoma), 2 with cerebral infarcts, and 1 with pansinusitis and epidural abscess. All but one aneurysm were distally located in intracranial circulation, 14 were in anterior, and the remaining 3 were in posterior circulation. The final diagnosis was based on aneurysm morphology, location, and clinical laboratory findings. Endovascular treatment was scheduled initially for all IIAs; 13 of 17 IIAs underwent endovascular parent vessel occlusion, 3 underwent spontaneous parent vessel occlusion while waiting for intervention, and the remaining patient was treated by intrasaccular coil occlusion. There were no instances of perioperative neurological complications. Late clinical and radiological outcomes included absence of endovascular treatment related to mortality and aneurysm recurrence. Endovascular treatment may be performed safely at the time of diagnosis for at least symptomatic IIAs under the protective effect of antibiotic treatment.
