  • Aortic dissection caused by blunt trauma is a rare injury that can be complicated by malperfusion syndrome resulting from obstruction of branch vessels of the aorta. Here, we present a case of traumatic type B aortic dissection with right renal and small bowel ischemia, successfully managed by endovascular fenestration.

  • 폰탄술식 후 수술사망률이 감소하고 생존자가 증가함에 따라 대정맥-폐동맥 순환의 부자연스러운 생리와 관련된 합병증이 발생하게 되었다. 이러한 혈역학적인 문제로 인하여 발생한 합병증 중의 하나가 단백소모성 장질환이다. 단백소모성 장질환은 폰탄술식 후에 발생하는 드물지만 매우 위험한 합병증이다. 많은 다른 치료경향이 제안되었지만 성공적인 치료보고는 제한되어 있다. 폰탄술식후 단백소모성 장질환이 발생한 3명의 환아에서 완전 대정맥-폐동맥 연결로 전환을 시행하였다. 완전 대정맥 폐동맥 연결로 전환함이 만족할 만한 치료방법임을 보고하는 바이다.

  • A 47-year-old man was referred for TEF. He underwent tracheostomy three months ago to maintain prolonged ventilator care. Computed tomography (CT) scan and fiberoptic examination showed bilateral vocal cord palsy with median fixation and about 2 inch sized long segmental tracheoesophageal fistula (TEF) tract along the necrotic cricoid and tracheal cartilages. Narrow field total laryngectomy was performed to remove devitalized cartilages and mucosa, and repair TEF. He discharged without complication except mild stenotic change of tracheal fenestration 19 days later.

  • Design load calculations which depend on the thermal characteristics of the building structure such as the wall, roof, and fenestration provide the basic data for selecting an HVAC system and its equipment. Most of domestic multi-family houses include a high thermal storage layer like massive concrete structure and a floor heating structure. This study is to compare the results of the design heating load between steady state and unsteady state calculation in order to comprehend the thermal storage effect in multi-family houses. The design heating load under the steady state calculation is estimated from 5.4% to 7.8% larger than that under the unsteady state in the typical floor of a multi-family house model. The design heating load considered the safety factors like a orientation and location factor also is 21.4% to 26.5% larger than that by the unsteady state calculation. So, the safety factors for use of the practicing engineer are analyzed as the main factor of a heating plant oversizing.

  • This present study analyzed temperature depreciation ratio of window inside surface by KS F 2295 'Procedure for determining fenestration product condensation resistance values'. it estimated window indoor surface condensation due to variable environmental condition. Performance of condensation resistance by using temperature depreciation ratio until applied Low-e and Ar glazing improved about 45% from 24 mm clear. Temperature depreciation ratio by KS F 2295 considers analytic index of window condensation due to variable boundary condition.

  • A 6-year-old Dachshund was presented with acute, non-localized pain without neurological dysfunction. Radiography revealed multiple calcifications of intervertebral discs and narrowing of disc space in the thoracolumbar region. Computed tomography and magnetic resonance imaging revealed calcified disc-like material entrapped in the left extraforaminal area and showed a displaced nerve root. Fenestration and removal of the extruded disc material were performed in a routine manner. Histopathological examination showed degenerative disc materials with severe calcification both in the nucleus pulposus and around the annulus fibrosis. Based on imaging, surgical, and histopathologic results, the dog was diagnosed with far lateral lumbar disc extrusion.

  • Knowledge of anatomical variations is important so as to avoid potential iatrogenic injury or misdiagnosis on imaging. Here we report an unusual finding and relationship between the tibial nerve and popliteal vein. During the routine dissection of an adult cadaver, it was noted that a branch of the tibial nerve in the popliteal fossa pierced the most distal part of the popliteal vein. This unusual finding is described and relevant reports in the literature discussed. Our hopes are that such a report might help surgeons avoid injury to such a fenestrated popliteal vein and the tibial nerve branch traveling through it therefore decreasing patient morbidity.

  • The present study evaluated the effects of guided tissue regeneration using xenograft material(deproteinated bovine bone powder), with and without Calcium sulfate membrane in beagle dogs. Contralateral fenestration defects (6 ${\times}$ 4 mm) were created 4 mm apical to the buccal alveolar crest of maxillary premolar teeth in 5 beagle dogs. Deproteinated bovine bone powders were implanted into fenestration defect and one randomly covered Calcium sulfate membrane (experimental group). Calcium sulfate membrane was used to provide GTR. Tissue blocks including defects with soft tissues which were harvested following four & eight weeks healing interval, prepared for histo-phathologic analysis. The results of this study were as follows, 1. In control group, at 4 weeks after surgery, new bony trabecular contacted with interstitial tissue and osteocytes lie cell were arranged in new bony trabecule. Bony lamellation was not observed. 2. In control group , at 8 weeks after surgery, scar-like interstitial tissue was filled defect and bony trabecule form lamellation. New bony trabecular was contacted with interstitial tissue but defect was not filled yet. 3. In experimental group, at 4 weeks after surgery, new bony trabecular partially recovered around damaged bone. But new bony trabecule was observed as irregularity and lower density. 4. In experimental group, at 8 weeks after surgery, lamella bone trabecular developed around bone cavity and damaged tissue was replaced with dense interstitial tissue. In conclusion, new bone formation regenerated more in experimental than control groups and there was seen observe more regular bony trabecular in experimental than control groups at 4 weeks after surgery. In control group, at 8 weeks after surgery, the defects was filled with scar-like interstitial tissue but, in experimental group, the defects was connected with new bone. Therefore xenograft material had osteoconduction but could not fill the defects. We thought that the effective regeneration of periodontal tissue, could be achieved using GTR with Calcium sulfate membrane.

  • 문명의 발달로 나날히 복잡해지는 사회 환경속에서 우리는 생명을 위협하는 수 많은 사고를 당하게 되며, 이럭 경우에 상기도를 유지하기 위한 기관절재술을 많이 시행하게 되는데, 때로는 기관협착등 이에 따른 여러가지 합병증을 유발하게 되는 경우가 있으며, 임상가들에게도 곤란한 문제를 갖어다 주고있다. 그러나 이러한 합병증은 수술방법의 개선과 항생제의 출현등으로 그 빈도가 많이 감소되기는 하였으나, 1969년 Lindholm은 술후성 기관협착증의 빈도를 1.5%내지 10%라고 했으며, 1969년 Donnelly, Mulder와 Rubush, 그리고 1971년 Andrew와 Pearson 등은 이들 원인의 대부분이 cuff 가 있는 기관삽입관이나, 기관케뉼(tracheal canula)의 부적합한 사용이나, 또는 감염에 의한 압박괴사(pressure necrosis)로 형성된다고 하였고, 협착부위로서 1972년 Bryce는 절개공(stoma)주위가 가장 많으며, 응급기관절개술시에 의사의 부정요법(mal-practice)도 원인이 될 수 있다고도 주의한 바 있다. 기관협착증의 치료로서 협착이 경미한 경우에는 일차적으로 세심한 관찰을 실시하면서 실리콘관(silicon tube)이나 스텐트(stent)를 사용하거나, 비강을 통한 삽관법(naso tracheal intubation)으로 기계적인 확장을 시도하며 (Schmiegelow, 1929, Montgomery, 1965), 육아조직이 형성되었을 경우에는 기관경검사하에서 이를 제거한 후에 steroid를 병용하는 편이 좋은데(Birck, 1970) 그밖에도 기관개찰술(Fenestration method, 백·홍 1974)이나 재수술(Revision)을 하기도 한다. 이러한 방법으로서도 치료가 불가능한 경우에는 그 협착 부분을 절제한 후에 단단문합술(End-to-End Anasto-mosis)을 시행하는 수도 있다. 저자들은 1967년 10월부터 1977년 3월까지 10연년간 세브란스병원에서 기관절개술을 받았던 1514례를 대상으로 일련의 조사를 실시하여 이들 중에서 기관협착증을 유발한 23례를 치료하였으며, 여기서 몇가지 지견을 얻었기에 보고하는 바이다.

  • 성인형 다낭성 간질환(adult polycystic liver disease, PLD)은 양성 질환으로 매우 드물고 상염색체우성 다낭성 신장질환(autosomal dominant polycystic kideny disease, ADPKD)을 동반한다. 다낭성 간질환(PLD)은 간실질에 여러 개의 미만성 낭성질환을 특징으로 하는 상염색체우성 유전성 질환이다. 간과 관련된 중요한 증상 또는 합병증이 발생할 수 있으며 이로 인하여 복강경 또는 간을 절제하거나 또는 절제 없이 천공설치술을 포함하는 치료가 이루어지며 간이식도 할 수 있다. 본 고찰에서는 복부 불쾌감이 있는 성인형 다낭성 간질환을 경험하였기에 초음파 검사와 복부 CT 소견에 대해 참고 문헌과 함께 보고하고자 한다.
