双下腔静脉伴睾丸静脉及肾上腺静脉变异1例

双下腔静脉的出现并不少见,国内外均有过报道,但同时伴左睾丸静脉和左肾上腺静脉注入左下腔静脉的变异却非常罕见。本文作者在解剖一具尸体标本时,发现1例双下腔静脉伴睾丸静脉、肾七腺静脉变异,为积累资料和为临床应用提供参考,现报告如下。     

双侧肾血管、睾丸血管变异1例

作者在解剖一老年男尸时,发现双侧肾的血管有多处变异,用数显游标卡尺对肾血管、睾丸血管的长度、外径进行了测量,现报道如下。尸体身高约180 cm,体型较为肥胖,外观发育正常,未见明显畸形。     

肾静脉以下段下腔静脉的形态特点及其临床意义

目的 :为涉及下腔静脉肾静脉以下段的手术提供该段下腔静脉及属支的解剖学数据。方法 :对 42例成人尸体标本下腔静脉的肾静脉以下段进行解剖和测量。结果 :该段下腔静脉长 (1 3 .0 3± 1 .76)cm ,宽 (2 .34± 0 .33)cm。静脉属支为 (8.74± 2 .0 2 )支 ,其中前壁有 66 .3 % ,上段有 66 .3 %。右睾丸 (卵巢 )静脉 83 .3 %开口于前壁 ,距左肾静脉开口上缘平面 (3 .56± 0 .85)cm。未见有腰升静脉 ,2 8.6 %例数的腰静脉与奇静脉或半奇静脉相连。腰静脉不成对且与腰动脉数目不相等 ,有 63 .8%的腰动脉有腰静脉伴行。结论 :下腔静脉肾静脉以下段的属支多而复杂 ,手术时应特别注意该段下腔静脉的上段及后壁。右睾丸 (卵巢 )静脉位置较稳定 ,可作为临床标志。传统概念的腰升静脉并不存在 ,有关腰静脉的传统描述与实际出入较大     

左睾丸动脉和静脉变异1例

睾丸血管变异的报道在国内外并不少见。其中,睾丸动脉存在着数目、起源和行程的变异[1～3],而睾丸静脉也存在着数目和注入部位的变异[4,5]。作者在解剖1具中年男性尸体时,发现其左睾丸动、静脉同时存在变异,实属罕见。     

左肾动脉及左睾丸动脉的变异1例

解剖一具成年男尸,发现左肾除有一支肾动脉外,尚有一支额外动脉。该动脉在肾动脉主干上方的0.7cm处发自主动脉腹部左侧壁,斜向左下,至肾门处全长为4.8cm,直径为4mm,共有5个分支:第1支于主干1.8cm处发出,长度为1.2cm,在距肾上极2.6cm处从肾上端入肾;第2支于主干2.2cm处发出,长度为2.     

双下腔静脉畸形合并滤器内血栓形成腔内治疗1例

<正>双下腔静脉畸形是指肾静脉以下左右2条对称的下腔静脉均出现畸形,其在下腔静脉变异中少见,占0.2%～3%,变异的主要原因是在胚胎期发育过程中双侧上主静脉持续存在而未退化^[1],通常无明显临床症状或体征,导致漏诊误诊。双下腔静脉畸形合并下腔静脉滤器内血栓形成的发生更是罕见。现结合我院的1例特殊病例和相关文献,探讨双下腔静脉畸形合并滤器内血栓形成的临床特征,为双下腔静脉畸形和滤器内血栓形成的早期识别和诊治策略提供参考,现报告如下。

Double inferior vena cava with interiliac vein: a case report and literature review

The duplication of the inferior vena cava (IVC) is a rare, but well-recognized anomaly. Duplicated IVC has a significant relevance for retroperitoneal surgery and venous interventional radiology. We report a case of duplicated IVC, which was observed during routine dissection of an 84-year-old Japanese female cadaver. The interiliac vein between the duplicated IVC ran obliquely upwards from left to right. We performed systematic literature review of published reports based on Pubmed and Medline from 1967 to 2011. Of 109 cases with IVC anomalies identified by the literature search, 22 cases (20.2%) displayed no interiliac anastomosis. The interiliac vein connecting duplicated IVC existed in 74 cases (67.9%). According to the running direction of the interiliac vein, we found that the vein ran from left to right in 42 cases, coursed from right to left in 19 cases, and ran horizontally in 13 cases. Thirteen left IVC displayed symmetrical-to-normal connection with the bilateral common iliac veins. Awareness of these venous variations is necessary to reduce surgical risk and to determine strategy in interventional radiology.     

双下腔静脉1例

患者男,69岁,因查体中超声检查发现左肾上极占位15天入院.无发烧、肋胁痛和血尿,无尿频、尿急和尿痛.CT检查时发现与左肾相连的另一支静脉于腹主动脉左侧继续向下走行.左右两只腔静脉在髂总动脉分叉上方有交通支(下腔静脉弓)(图1～3).腹腔镜左肾癌根治术中证实左肾静脉下面与一条直径约1.2 cm的纵行静脉相连,术后病理为左肾透明细胞癌.     

Left inferior vena cava with regressed right inferior vena cava

A left inferior vena cava was found in the cadaver of an 88-year-old Japanese man during a student dissection course at Kumamoto University School of Medicine. The right common iliac vein ascended obliquely toward the left behind the right common iliac artery and united with the left common iliac vein to form the inferior vena cava in front of the fifth lumbar vertebral body behind the left common iliac artery. The inferior vena cava ascended on the left side to the aorta, and after the left renal vein joined to it at the level of the third lumbar vertebral body, it turned obliquely to the right and crossed superficially to the aorta. At the right side of the aorta, the common stem of the third lumbar vein and the posterior renal vein was joined to the oblique part. The inferior vena cava then ascended, receiving the right renal vein as it would normally. The inferior vena cava is thought to develop symmetrically but this left inferior vena cava shows a persistence of the left channel of the infrarenal part, which normally disappears. Although the common stem of the veins that joined to the oblique part on the right side did not continue to the right common iliac vein, gross anatomical findings suggested it to be the remnant of the right inferior vena cava.     

Double thoracic drainage of a left inferior vena cava

Summary The authors report a case of left IVC with a preferential hemiazygos-azygos drainage associated with an accessory left superior intercostal vein drainage. This exceptional congenital malformation which finds its place in polysplenia was studied by cavography, CT and MR imaging.
