  • 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.

  • The suitable tag was investigated based on the cumulative mortality, blood chemistry and histopathology of olive flounder, Paralichthys olivaceus. The dissection of opercle, 50% dissection of pelvic fin and 100% dissection of pelvic fin was used in the experiment. Cumulative mortality of dissection of opercle group was high. The dissection of opercle and 100% pelvic fin dissection groups was showing histological changes after 13days of tagging: purulent inflammation in the liver, fibrous inflammation in the body kidney, hyperplastic ellipsoide capillary in the spleen. As the results, 50% pelvic fin cutting group is the most effective out of them.

  • 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.

  • 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.

  • Background: To avoid the major mobidity associated with bilateral radical neck dissection, modified radical neck dissection has become established as an effective adjunctive procedure in the management of head and neck cancer. But several studies reported early postoperative internal jugular vein(IJV) occlusion in patients who underwent modified radical neck dissection. Objectives: To determine internal jugular vein patency following modified radical neck dessection performed in various head and neck cancer and to identify factors associated with venous occlusion. Materials and Methods: From Aug. 1996 to Oct. 1997, twenty three patients underwent either unilateral or bilateral modified radical neck dissection; 19 males and 4 females, ranging in age from 28 to 75 were retrospectively examined. All patients had a preoperative doppler imaging or CT or both for their initial evaluation. A follow-up examination was obtained(after a minimum postoperative period of 2 months and a maximum one of 4 months). Results: Thirty-four IJVs were examined. All but six IJVs examined were found patent postoperatively. The preservation rate of patency of the IJV in modified radical neck dissection was found to be high(28 of 34 IJVs or 82%). Conclusion: The preservation rate of patency of the IJV in modified radical neck dissection was found to be high. These results favor the use of modified radical neck dissection for IJV preservation, particularly in bilateral neck dissection. A retrospective chart review revealed that trauma of the vessel and extrinsic compression of the vein by the musculocutaneous flap or recurrent carcinoma in the neck may be the cause of the vein occlusion.
