在解剖一具约45岁男性藏族尸体时,发现右侧腹壁下动脉起点异常,此异常在股疝手术中有一定的实用参考价值,现报道如下。闭孔动脉与腹壁下动脉共干起自髂内动脉,共干长2.5cm,外径4.0mm,共干行至距闭膜管2cm 处,发出一支腹壁下动脉(外径2.5mm)和闭孔动脉(外径3.5mm)(见附图),腹壁下动脉沿盆壁前上行于腹环的内侧(距腹环内缘约4mm)并继续行向上内入腹 相似文献

异常闭孔动脉报导较多,出现率在20%左右,多与腹壁下动脉合干起白髂外动脉,经闭孔管进入股内侧肌群,而与腹壁下动脉合干起自髂外动脉,经腹股沟韧带深面进入股内侧区供应内收肌群的异常闭孔动脉尚未见有报导。现将在制作教学标本中发现一例报导如下。男性,约60岁,重庆地区人,左侧除起 相似文献

目的 观察异常闭孔动脉的走形、分布,并对其盆内段进行测量和定位,为腹股沟区相关手术提供可靠的解剖学基础。 方法 解剖研究37侧成人骨盆标本,对闭孔动脉进行观测和分类,并测量闭孔动脉盆内段长度,起始端外径,闭孔管处外径,以及闭孔动脉入闭孔处和髂前上棘与耻骨联合连线中点的距离。 结果 在37侧标本中,异常闭孔动脉出现率为18.92%。异常闭孔动脉与腹壁下动脉共干(1.57±0.12)cm发出,盆内段平均长度(4.05±0.49)cm,起始处平均外径(2.52±0.87)mm,闭膜管处闭孔动脉平均外径(2.14±0.72)mm,入闭孔处和连线中点的距离(3.63±1.29)cm。异常闭孔动脉多与腹壁下动脉共干,之后绕股环或跨过股环,紧贴盆壁下降至闭孔处。 结论 正是由于异常闭孔动脉的特殊性质,在腹股沟区及骨盆、髋区骨折固定手术,甚至肿瘤治疗、淋巴结清除术中,术者当引起重视。 相似文献

在正常情况下,闭孔动脉通常起于髂内动脉的前干,沿骨盆侧壁行向前下方,经盆内筋膜与腹膜之间,输精管盆侧或子宫圆韧带自其内侧跨过,其上、下分别有闭孔神经和闭孔静脉与之伴行,至闭孔上方进入闭膜管,出骨盆至股部,分为前后两终支。闭孔动脉在盆内除分支至髂骨、髂肌、膀胱等外,尚发出一耻骨支,耻骨支沿耻骨后面内进,与对侧同名支以及腹壁下动脉的耻骨支吻合,有时这个吻合支变得很粗,而正常的闭孔动脉很小或不存在,由该吻合支所代替,这种粗大吻合支即为异常闭孔动脉(椐资料统计约占169/6-209/6)。笔在进行教学标本制作时,发现一成年女性右侧闭孔动脉变异,而左侧闭孔动脉与上述正常闭孔动脉描述无异。现将变异情况报告如下。 相似文献

We observed two rare patterns of femoral artery ramification in the bilateral thighs of an 83-year-old male cadaver. In the
right thigh, the lateral circumflex femoral and deep circumflex iliac arteries formed a common trunk, while in the left, the
medial circumflex femoral, inferior epigastric, and obturator arteries formed a common trunk. In the left pelvis, the obturator
artery comprised branches from the inferior epigastric, superior gluteal, and inferior gluteal arteries. We describe this
rare case and discuss the genesis and clinical significance of these variations. 相似文献

Definitive obturatory artery forms as a result of uneven growth of anastomosis of external and internal iliac arteries which is connected with peculiarities of regional organogenesis. 2 crucial periods--renal--and the period of gonade obstruction (the end of intrauterine development) were distinguished in morphogenesis of pubic anastomosis of iliac arteries. Sex related peculiarities of obturatory artery development were found in the second period. 相似文献

The right subclavian artery was found to be retroesophageal, and the right vertebral artery originated from the right common carotid artery in a 46-year-old female cadaver. The right subclavian artery stemmed from the upper portion of the thoracic aorta, posterior and inferior to the origin of the normal left subclavian artery. The right and left common carotid arteries originated from the aortic arch in close proximity. Compression of the trachea anteriorly could not be demonstrated. The right inferior laryngeal nerve was nonrecurrent. A brief review of the literature shows the importance of knowledge concerning the aberrant right subclavian artery for the roentgenologist and the surgeon in the treatment of patients with this vascular anomaly. 相似文献

正对1具男性尸体进行解剖时,发现右锁骨下动脉和右颈总动脉直接起自于主动脉弓,致主动脉弓分支变异(图1),而正常的右锁骨下动脉和右颈总动脉起自头臂干[1],相对于国内李永胜[2]等人的报道,此类变异数值、具体起点均有差异。根据《中国人解剖学数值》,本例锁骨下动脉变异出现率为1.48%,为积累国人解剖学数据和为临床治疗提供参考,现报 相似文献

Background: There is general confusion about a branch of the posterior segment of the right coronary artery that has been referred to as 1) the lower trunk of a divided right coronary artery; 2) a posterior reflection of the right marginal artery; 3) the ramus lateralis; and 4) a posterolateral branch or a posterior descending artery. Materials: Three hundred human hearts were studied by direct observation, X-ray films, and corrosion casting. Results: This branch of the right coronary artery arises either after the right marginal artery (in 84% of hearts) or it constitutes the continuation of this artery in the remaining 16%. We named it the posterior right diagonal artery (PRDA). It was found in 14% of 266 hearts of right dominant type. It was present in 39% when the length of the posterior descending artery (PDA) was shorter than half of the length of the posterior interventricular sulcus (PIS) and in 6% when it was longer. When the PRDA originated directly from the RCA, the RMA appeared underdeveloped; the PRDA always occupied the inferior part of the PIS and appears either as continuation of a short PDA or as a replacement for a long PDA from the point where this artery leaves the PIS to enter the posterior wall of the left ventricle. The PDRA when present serves as a bridge between the RCA and the left anterior descending artery. Conclusions: These findings are of practical importance for the correct interpretation of coronary arteriographies and in the field of coronary artery surgery. © 1994 Wiley-Liss, Inc. 相似文献
