Selective transarterial embolization with n-butyl-2-cyanoacrylate for the treatment of arterial hemorrhage after third molar extraction
Neuroradiology, 2013Co-Authors: Yoshiko Sagara, Hiro Kiyosue, Shuichi Tanoue, Ryuichi Shimada, Norio Hongo, Tatsuyuki Kohno, Kenji Kawano, Hiromu MoriAbstract:Introduction Comprehensive reports concerning selective embolization for arterial bleeding from third molar removal have not been published. We analyzed cases of arterial bleeding from third molar extraction that required transarterial embolization, and we demonstrate representative cases. Methods Five consecutive patients (three men and two women, aged 24 to 37 years) who underwent transarterial embolization at our institution were included in this study. Four of them showed postoperative bleeding after lower third molar removal, and one suffered bleeding after upper third molar extraction. The period of time from extraction to embolization varied from 5 h to 5 weeks. Results Angiography revealed pseudoaneurysms at the Inferior Alveolar Artery in four cases and at the superior Alveolar Artery in one case. The pseudoaneurysms were selectively embolized using 25–33 % n -butyl-2-cyanoacrylate (NBCA)–lipiodol. All of the cases showed good results angiographically and clinically. Transit hypoesthesia at the region of the mental nerve was observed in one patient. Conclusion Selective transarterial embolization is an effective technique for arterial bleeding from third molar removal when it is difficult to obtain hemostasis by dental procedures. Injection of NBCA can be useful when the Alveolar Artery is too small to embolize with coils.

pseudoaneurysm of the Inferior Alveolar Artery after surgical curettage for keratocystic odontogenic tumor a case report
Maxillofacial plastic and reconstructive surgery, 2013Co-Authors: Sangchang Lee, Jongbae Kim, Byungrho Chin, Jin Wook Kim, Chinsoo Kim, Taegeon KwonAbstract:Abstract Pseudoaneurysm of the Inferior Alveolar Artery after Surgical C urettage for Keratocystic Odontogenic Tumor: A Case Report Sang-Chang Lee, Jong-Bae Kim 1 , Byung-Rho Chin 2 , Jin-Wook Kim, Chin-Soo Kim, Tae-Geon Kwon Department of Oral and Maxillofacial Surgery, Kyungpook Nationa l University School of Dentistry, 1 Department of Dentistry, Keimyung University College of Medicine, 2 Department of Dentistry, Yeungnam University College of MedicinePseudoaneurysms are rare complications of orgthognathic surgery , trauma or other surgical procedures in the head and neck regions. Surgical approach is a routine procedure of bleeding c ontrol. However, bleeding control using angiography and emboliz a-tion can also be an excellent method. We experienced pseudoaneu rysm of the Inferior Alveolar Artery occurring after surgical curettage of cystic lesion. The 33-year-old man who underwent s urgical curettage of keratocystic odontogenic tumor was present ed with severe bleeding in the right mandible ramal inner surface 14 days after the surgical curettage. After hemostasis with vaseline gauze packing and pressure, bleeding temporarily stopp ed. However, bleeding started after 14 days and soon it has been continued. Finally, the patient was diagnosed as pseudoane urysm of the Inferior Alveolar Artery from the enhanced-compute d tomography images, and angiographic embolization was performed successfully. We report a rare case of pseudoaneurysm of the Inferior Alveolar Artery after benign tumor curettage and review of the previewer’s literature.Key words:False aneurysm, Inferior Alveolar Artery, Angiography, Therapeu tic embolization, Keratocystic odontogenic tumor

Radiological assessment of the Inferior Alveolar Artery course in human corpse mandibles
European Radiology, 2015Co-Authors: Kristina Bertl, Lena Hirtler, Toni Dobsak, Patrick Heimel, André Gahleitner, Christian Ulm, Hanns PlenkAbstract:Objectives CT assessment of the entire course of the Inferior Alveolar Artery (IAA) within the mandibular canal. Methods After contrast medium injection (180 or 400 mg/ml iodine concentration) into the external carotid arteries of 15 fresh human cadaver heads, the main IAA’s position in the canal (cranial, buccal, lingual or caudal) was assessed in dental CT images of partially edentulous mandibles. Results The course of the main IAA could be followed at both iodine concentrations. The higher concentration gave the expected better contrast, without creating artefacts, and improved visibility of smaller arteries, such as anastomotic sections, dental branches and the incisive branch. The main IAA changed its position in the canal more often than so far known (mean 4.3 times, SD 1.24, range 2–7), but with a similar bilateral course. A cranial position was most often detected (42 %), followed by lingual (36 %), caudal (16 %) and buccal ( 6 %). Conclusions With this non-invasive radiologic method, the entire course of the main IAA in the mandibular canal could be followed simultaneously with other bone structures on both sides of human cadaver mandibles. This methodology allows one to amend existing anatomical and histological data, which are important for surgical interventions near the mandibular canal. Key points • Contrast medium injection displayed the Inferior Alveolar Artery’s course on mandibular CTs • An iodine concentration of 400 mg/ml enabled visibility until the chin • Frequent position changes of the Artery in the mandibular canal were detected • Cranial and lingual positions were most often determined • Course similarities on the respective left and right sides were found

Modified technique for the exposure of the Inferior Alveolar nerve in rats
Journal of pharmacological and toxicological methods, 2013Co-Authors: Ammar Kassab, M. Hage, Suhayl J. Jabbur, Jose Johann ChidiacAbstract:The Inferior Alveolar nerve (IAN), a branch of the mandibular division of the trigeminal nerve, is a major component of the neurovascular bundle along with the Inferior Alveolar Artery and vein. In rats, when exposed using an external oral approach while remaining intact, it can serve as an important tool to study the different effects of neuromediators and assess the role of different groups of nerve fibers. This paper describes a new technique to expose this nerve giving some experimental results to support its usefulness.
