  • Although many imaging modalities can play some roles in the diagnosis of vertebral artery dissection (VAD), digital subtraction angiography (DSA) remains the gold standard method, with the highest detection rate and ability to assist in planning for endovascular treatment. However, this tool is often avoided in children because its invasive nature and it exposes them to radiation. High resolution magnetic resonance imaging (HR-MRI) have been suggested to be a reliable and non-invasive alternative, but it has never been discussed in children in whom vertebral artery dissection is a rare condition. In this report, we evaluate a case of a 2-year-old child who initially presented with cerebellar symptoms, and was early diagnosed with vertebral artery dissection using HR- MRI and was successfully treated.

  • Aortic dissection is an uncommon, life-threatening medical emergency that is associated with a high mortality rate, and death from aortic dissection is mainly related to secondary complications, namely cardiac tamponade, severe aortic regurgitation, acute myocardial infarction, and abdominal organ vessel obstruction. Hence, prompt and accurate diagnosis followed by proper treatment is important for patient survival. Herein, we present a rare case of sudden death after aortic dissection with concomitant acute myocardial infarction and cardiac tamponade.

  • Purpose: The transaxillary approach for breast augmentation has been advocated for patients and surgeons for several decades. However, this blind technique had many disadvantages including, traumatic dissection, difficult hemostasis, displacement of implants, and ill-defined asymmetrical location of inframammary crease. In the present study, the precise endoscopic electrocautery dissection was applied to eliminate the limits of blunt dissection throughout the procedures. Methods: From December 2006 to December 2007, a total of 103 patients with an average age of 29.5 years underwent endoscopic assisted transaxillary dual plane augmentation mammoplasty. The mean implant size was 243 cc with the range between 150 and 350 cc. Through a 4 cm axillary incision, electrocautery dissection for submuscular pockets was carried out under the endoscopic control. The costal origin of pectoralis muscle was completely divided to expose subcutaneous tissue and to make type I dual plane. Results: Using the endoscopic dissection, we achieved good aesthetic results including a short recovery period, less morbidity, and symmetrical well-defined inframammary crease. Type I dual plane procedure could support the consistent inframammary fold shape and be applied to most patients without breast ptosis. Minor complications did not occur, however, four major complications of capsular contracture occurred. Conclusion: In contrast to the era of the blind techniques, endoscopic assisted transaxillary dual plane breast augmentation can now be performed effectively and reproducibly. With Its advantage, the axillary application of endoscopy for augmentation mammaplasty is useful to achieve the optimal cosmetic outcomes.

  • Parotidectomy, combined with neck dissection, is not rare situation in case of parotid malignancy. It is common to accomplish the parotidectomy and neck dissection separately. But there are numerous lymph nodes surrounding the marginal mandibular branch of facial nerve and facial artery and vein. And so, Mono-bloc dissection of the parotid gland and neck specimen is neccessary to completely resect these lymph nodes with preserving the marginal mandibular branch of facial nerve. We are reporting three cases of mono-bloc dissection of the parotid gland and neck specimen.

  • Primary dissection of the renal artery is rare. Spontaneous renal artery dissection can be associated with diseases such as medial degeneration, neurofibromatosis, syphilitic arteritis, tuberculosis, polyarteritis nodosa, Marfan syndrome, fibromuscular dysplasia, or Ehlers-Danlos syndrome (EDS). Among these causes, EDS related renal artery dissection is very rare worldwide and has not been previously reported in Korea. EDS are a group of heritable connective tissue disorders characterized by fragility of the skin and hypermobility of the joints. We describe the case history of a young man who presented with left side flank pain, hypermobility of the hand joints and showed left renal artery dissection on computed tomography and angiography that turned out to be the first complication of vascular type EDS.

  • Video-assisted thoracoscopic surgery (VATS) has been established as the surgical approach of choice for lobectomy in patients with early-stage non-small cell lung cancer (NSCLC). Patients with clinical stage I NSCLC with no lymph node metastasis are considered candidates for VATS lobectomy. To rule out the presence of metastasis to lymph nodes or distant organs, patients should undergo meticulous clinical staging. Assessing patients' functional status is required to ensure that there are no medical contraindications, such as impaired pulmonary function or cardiac comorbidities. Although various combinations of the number, size, and location of ports are available, finding the best method of port placement for each surgeon is fundamental to maximize the efficiency of the surgical procedure. When conducting VATS lobectomy, it is always necessary to comply with the following oncological principles: (1) the vessels and bronchus of the target lobe should be individually divided, (2) systematic lymph node dissection is mandatory, and (3) touching the lymph node itself and rupturing the capsule of the lymph node should be minimized. Most surgeons conduct the procedure in the following sequence: (1) dissection along the hilar structure, (2) fissure division, (3) perivascular and peribronchial dissection, (4) individual division of the vessels and bronchus, (5) specimen retrieval, and (6) mediastinal lymph node dissection. Surgeons should obtain experience in enhancing the exposure of the dissection target and facilitating dissection. This review article provides the basic principles of the surgical techniques and practical maneuvers for performing VATS lobectomy easily, safely, and efficiently.

  • Background: The study is descriptive research study to investigate the self-directed learning ability to explore the facts that influence of anatomy using cadaver dissection beginning nursing students. Methods: A descriptive research design was used. The data was collected from 31st May to 7 June, 2016. The participants were total 121 first-year nursing students in C University. This anatomy practicum course was composed of three session, and each session was composed of 3hours, 60minutes of body structure and anatomy lecture, 90 minutes of cadaver dissection, and 30minutes of summary. Results: The results of the study showed that satisfaction with cadaver dissection was statistically significant in the usefulness in connection with the major of nursing (r=.543, P<.001), educational understanding (r=.465, p<.001), and nursing learning motivation (r=.517, p<.001). As the nursing learning motivation increased, self-directed learning ability increased. Also nursing learning motivation influenced self-directed learning (${\beta}=0.266$, p<.01). Conclusion: It is necessary to develop a program that can link theoretical education with practicum education of anatomy using cadaver dissection for efficient learning of the anatomy major courses of nursing students.

  • Aortic dissection is one of the causes of acute ischemic stroke. Endovascular recanalization therapy (EVT) has emerged as an essential treatment for acute ischemic stroke due to large artery occlusion. However, it is rarely performed in the situation of hidden aortic dissection (AD). Two patients presented to the emergency room with focal neurologic deficits. The first patient was diagnosed with right internal carotid artery (ICA) occlusion. Angiography revealed that the ICA was occluded by the dissection flap. After a stent deployment in the proximal ICA, the antegrade flow was restored. The patient was diagnosed with AD on chest computed tomography (CT) after EVT. For the second patient, intraarterial thrombectomy was performed to treat left middle cerebral artery occlusion. AD was first detected on echocardiography, which was performed after EVT. Herein, we report successful endovascular recanalization therapy performed in two patients with acute ischemic stroke in the situation of undiagnosed aortic dissection. We also reviewed previous case reports and relevant literature.

  • 저자들은 변형적 경부청소술을 시행받은 두경부암환자 23례를 대상으로 술 후 내경정맥의 유지여부을 후향적으로 연구한 결과 총 34측 경부청소술 중 28측(82.4%)에서 내경정맥이 유지됨을 알 수 있었다. 이는 기존의 연구결과와 비슷한 개존율임을 알 수 있었다. 내경정맥의 폐쇄요인으로 술중 정맥의 손상과 혈류정체, 장기간 수술로 인한 정맥벽의 건조, 수술시 제거되는 근막의 소실이 정맥의 유착과 압박을 초래하는 것으로 알려져 있다. 또한 다양한 치료방법과 술 후 발생하는 여러 요인들에 의해 내경정맥이 영향을 받는데 본 연구에서는 국소재발과 창상합병증등이 주된 영향을 준 것으로 판단된다. 방사선치료는 다른 복합적인 요소가 결부되어 단독적인 영향으로 판단하기엔 충분치 않으며 양측 경부청소술은 내경정맥의 폐색과는 무관한 것으로 생각된다. 본 연구는 증례수가 작고 추적기간이 짧은 한계점이 있으므로 향후 좀 더 많은 증례와 충분한 추적기간을 통한 연구가 필요하리라 판단된다.
