| 설명 | 생물의 개체 발생도중에 구조-생김새 등의 비정상화 된 이상. 생물의 발생중에 생기는 각종 형태적 특징에는 개체차도 있고, 또 그 차에도 대소가 있으나 변화의 범위에는 자연히 한계가 있다. 이 범위를 벗어난 형태일 때 이것을 기형이라 한다. 병이 개체 출생시 또는 출생 후의 신생아기 이후에 발병하는데 대개 기형은 발육도중인 태생기에서 출생 사이에 생긴 개체 전체 또는 부분적인 장기형성 장애이며 선천성으로 병적인 상태이다. 통상적인 병과는 본질적으로 구별한다. 성립시기는 기형의 종류에 따라 다르지만 태생 8~10주경에 시작되어 태생 10주~3개월까지에 생기는 것으로 생각되고 있다. 기형의 종류는 크게 어떤 기관의 ① 과잉형성, ② 결여, ③ 불완전형성(심장중격결손), ④ 위치의 이상 등으로 나눌 수 있다. 기형을 일으키는 원인에는 유전적인 영향, 호르몬의 이상, 일시적-국부적인 영양의 과다, 바이러스나 방사선, 산소결핍, 기타 체내 미생물의 영향 등 내적인 것, 발생 과정에서의 파열 따위의 외적인 것이 있으며, 외적인 원인이 내적인 원인을 유발하는 일도 많다. 환경적 원인으로는 온도 등의 물리적 조건, 호르몬이나 화학약품 등이 있다. 이것들은 실험발생학이나 실험형태학-유전학의 입장에서 점차로 밝혀지고 있지만 아직 분명하지 않은 부분도 적지 않다. 기형의 연구는 정상적인 발생메커니즘을 연구하는데 중요한 단서가 된다. |

| arteriovenous malformation | <anatomy, embryology> A tangled collection of abnormal blood vessels where there is an abnormal communication between the arterial and venous systems. The afferents flow directly into the venous efferents without the usual resistance of an intervening capillary bed. They are mostly congenital. If large enough, they may produce a shunt of sufficient magnitude to raise the cardiac output. Common sites include; skin, liver, brain, brainstem and spinal cord, where they may cause headaches, seizures or bleeding (subarachnoid haemorrhage). See: arteriovenous fistula, cerebral arteriovenous malformations. Synonym: haemangioma (20 Jun 2000) |

| malformation | <embryology> A morphologic defect resulting from an intrinsically abnormal developmental process. Origin: L. Malus = evil, formatio = a forming (18 Nov 1997) |
| cerebellomedullary malformation syndrome | <radiology> Chiari I herniation of medulla and cerebellar tonsils, 4th ventricle in normal position, Chiari II herniation of medulla, tonsils, vermis, 4th ventricle at foramen magnum, myelomeningocele, aqueductal stenosis most likely to be hydrocephalus, Chiari III further herniation, 4th ventricle below foramen magnum, encephalocele or myelomeningocele associated with: agenesis of corpus callosum, syrinx (12 Dec 1998) |
| congenital malformation | Abnormal formation of a structure evident at birth. (12 Dec 1998) |
| cystic adenomatoid malformation of lung | <radiology> Only true pulmonary cystic disease of newborn, three X-ray types: multicystic, walls of varying thickness, multicystic, one large dominant thin-walled cyst, solid, mediastinal shift common, cysts often contain foetal lung fluid, Treatment: surgery Cf: congenital lobar emphysema (12 Dec 1998) |
| cystic adenomatoid malformation of lung, congenital | A developmental anomaly that usually becomes apparent in the neonatal period with progressive respiratory distress. This malformation is a focal pulmonary dysplasia characterised by a multicystic mass of terminal bronchiolar structures. Ccam is classified into 3 separate types (I, II, III) depending on cyst size. (12 Dec 1998) |
| arteriovenous | <anatomy> Both arterial and venous, pertaining to or affecting an artery and a vein. (18 Nov 1997) |
| arteriovenous anastomosis | <anatomy> A vessel that directly interconnects an artery and a vein, and that acts as a shunt to bypass the capillary bed. Not to be confused with surgical anastomosis, nor with arteriovenous fistula. (12 Dec 1998) |
| arteriovenous aneurysm | <anatomy> A dilated arteriovenous shunt where there is communication between an artery and a vein, sometimes congenital. (05 Mar 2000) |
| arteriovenous carbon dioxide difference | <physiology> The difference in carbon dioxide content (in ml per 100 ml blood) between arterial and venous blood. (05 Mar 2000) |
| arteriovenous fistula | <surgery> The surgical joining of an artery and a vein under the skin for the purpose of haemodialysis. Larger arteriovenous shunts can place strain on the heart since arterial blood is diverted back to the venous circulation before it has a chance to deliver nutrients and oxygen to the body tissues. (27 Sep 1997) |
| arteriovenous oxygen difference | <physiology> The difference in the oxygen content (in ml per 100 ml blood) between arterial and venous blood. (05 Mar 2000) |
| arteriovenous shunt | <anatomy, surgery> A direct connection between an artery and vein. Most often due to the surgical joining of an artery and a vein under the skin for the purpose of haemodialysis. Larger arteriovenous shunts can create significant extra workload on the heart since arterial blood is diverted back to the venous circulation before it has a chance to deliver nutrients and oxygen to the body tissues. (20 Jun 2000) |
| arteriovenous strabismus syndrome | <syndrome> Strabismus in which the angle of deviation is more marked on looking upward or downward. See: A-esotropia, V-esotropia, A-exotropia, V-exotropia. (05 Mar 2000) |
