The hepatic falciform artery is an occasional terminal branch of the left or middle hepatic artery, and may provide an uncommon
but important collateral route when the principal visceral arteries are occluded. 相似文献

Laparoscopic enucleation of a renal cell carcinoma 总被引:1,自引:0,他引:1
R. C. Luciani M. Greiner J. C. Clement A. Houot J. F. Didierlaurent 《Surgical endoscopy》1994,8(11):1329-1331
The purpose of this study was to report on the feasibility of laparoscopic excision of renal cell carcinoma. An 81-year-old female with renovascular disease underwent a laparoscopic excisional operation for a 2-cm tumor localized in the left kidney.Pathological evaluation showed a low-grade tumor without any extension through the renal capsule (grade I Hand Broder, stage I Robson). The postoperative course was uneventful; there was minimal postoperative pain. The patient was discharged home on the sixth day. Laparoscopic excision would appear to be a safe and effective technique in selected cases. 相似文献

Summary Two arterial systems contribute to the blood supply of the penis. The deeper system, responsible for supplying the erectile tissues, arises from the internal pudendal arteries (a. pudendae internae), or sometimes from an accessory internal artery. Four branches, either collateral or terminal, should be considered: the artery to the bulb of the penis, the urethral artery, the deep artery of the penis and the dorsal artery of the penis. Variations are frequently present in the origin, distribution and symmetry of these arteries, but on the whole the blood supply is organised into three planes, inferior or ventral, middle and deep, superior or dorsal. These three planes are complementary: when the blood supply to any one of them is occluded, at whatever level this may be, the blood supply is supplemented by the plane immediately above it. Arteriograms should be interpreted with caution because anatomical variations may at first sight be taken for pathological change.The superficial system, supplying the tissues around the erectile organs, arises from the lateral inferior pudendal arteries. Three types of supply have been described, according to whether the right and left arteries have a symmetrical distribution or whether the arterial network arises in large part or totally from one side.
Contribution à l'étude de la vascularisation artérielle du pénis
Résumé Deux systèmes artériels participent à la vascularisation du pénis. Le système profond, tenant sous sa dépendance les organes érectiles, a pour origine les artères honteuses internes (a. pudendae internae), parfois une artère interne accessoire. Quatre branches, collatérales ou terminales sont à considérer: l'artère du bulbe du pénis, l'artère urètrale, l'artère profonde du pénis, l'artère dorsale. Il existe de fréquentes variations dans l'origine, la distribution et la symétrie de ces artères mais, dans son ensemble, la vascularisation est organisée selon trois plans, inférieur ou ventral, moyen ou profond, supérieur ou dorsal. Ces trois plans sont complémentaires: lorsque l'un d'eux s'épuise, à quelque niveau que ce soit, le relais est pris par le plan immédiatement supérieur.Le système superficiel, vascularisant les enveloppes provient des artères honteuses externes inférieures. Trois types de vascularisation sont décrits, selon que les deux artères droite et gauche ont une distribution symétrique ou que le réseau artériel provient en majeure partie ou totalement d'un seul côté.相似文献

In recent years, the development of noninvasive imaging modalities for exploration of the kidney has markedly reduced the
use of angiography in the evaluation of renal masses. Presently, it is not required in routine practice to evaluate renal
masses. Ultrasound is the most efficient procedure in detecting renal tumor. It is acknowledged that arteriography has a limited
diagnostic and staging value compared with CT and MRI for the assessment of renal cell carcinomas (RCC). Most urologists recommend
partial nephrectomy or tumor enucleation in an effort to preserve as much as possible functioning renal tissue. In such cases
a preoperative map of the renal vasculature is not needed. Information on the main renal artery(ies) and segmental renal arteries
can be provided with spiral CT or dynamic MR angiography. Arteriography remains useful in exceptional situations. Interventional
arteriography is becoming an important part. It is indicated by means of selective embolization for the treatment of potentially
bleeding tumor (i. e. angiomyolipoma) or in emergency in cases of acute hemorrhage. Less frequently, it may be proposed as
a palliative procedure for inoperable patients with huge renal tumor. Two other indications of interventional arteriography
are acknowledged. Some urologists request preoperative embolization of the tumor-harboring kidney to decrease/avoid extensive
blood loss during surgery and/or to facilitate surgery with huge renal tumors when the renal vessels are difficult to reach.
The complications of nephron-sparing surgery (partial nephrectomy or tumor enucleation) related to bleeding or arteriovenous
fistulas may be cured by arterial embolization.

The value of arteriography in the management of aneurysmal bone cyst is demonstrated in three cases in which the most vascular area of the tumor was the earliest and/or only one to recur. The prognostic value of arteriography is postulated. 相似文献

The hepatic falciform artery is a small vessel that arises as a terminal branch of the middle or left hepatic artery. Its anatomy and clinical importance have been described in several recent reports. During dissection of a cadaver, this artery is generally found connected with the ensiform branch of the internal mammary artery. However, to our knowledge, anastomosis has not previously been described radiologically. 相似文献

Outcome of acute nonvariceal gastrointestinal haemorrhage after nontherapeutic arteriography compared with embolization 总被引:1,自引:0,他引:1

In acute nonvariceal gastrointestinal (GI) bleeding, immediate arteriographic haemostasis is presently assumed to be a therapeutic
advantage. This study assesses whether the risk of a delayed haemostasis, caused by arteriographic findings precluding embolization,
might influence patient outcome. We performed a 5.5-year retrospective database search to find all patients referred for arteriography
to arrest acute nonvariceal GI bleeding with embolization. The embolized and nonembolized patients were compared for differences
in baseline characteristics and bleeding parameters. In both groups the outcome of all endoscopic or surgical interventions
after catheterization was included in the follow-up. Clinical success (at 30 days, after all therapy) and in-hospital mortality
in the embolized and nonembolized group were compared. We retrieved 63 nonembolized bleedings in 58 patients and 49 embolized
bleedings in 49 patients. In the nonembolized group, transfusion need and haemodynamic instability were significantly less
severe. Forty-two of 63 (66%) nonembolized bleedings persisted requiring haemostasis by surgery (n=23), endoscopy (n=13) or supportive transfusions. Thirteen of 49 (27%) embolized bleedings recurred and were managed by surgery (n=7), endoscopy (n=3) or transfusion. Overall clinical success rate was 88.9% (56 of 63) in the nonembolized and 87.8% (43 of 49) in the embolized
group. Mortality rate was 17.2% (10 of 58) in the nonembolized vs 30.6% (15 of 49) in the embolized patients (P=0.115). Whether or not arteriographic findings afforded the opportunity to embolize, outcome of acute nonvariceal GI bleeding
did not differ significantly; however, patients undergoing embolization were more critically bleeding and ill. 相似文献
