[Internal iliac artery: functional anastomosis value and pelvic surgery application].

The vascularization of the intra and extra pelvic organs of adults, children and neonates (male and female) is studied in 17 pelvis, in which the vascular system has been injected with colored Altufix p10 and gelatinous india ink. The pelvic region constitute a true vascular crossroad of two anastomotic networks, one arterial, originate from the visceral and parietal branches of iliac internal and external arteries, femoral and abdominal aorta by inferior mesenteric artery; the other one, which morphology is incompletely superposable in diameter. Each organ is tributary of characteristic vascular system from adventitious to mucosa with direct or recurrential manner between striated muscle fibers and mucosal layers.

Anatomical study of the variations in innervation of the orbicularis oculi by the facial nerve.

While the divisions of the facial nerve in the face are well known, the innervation of the orbicularis oculi by the different distal branches of the facial nerve is poorly described. To determine which branches of the facial nerve play a role in this innervation, the facial nerve was dissected in 30 fresh cadavers. The innervation of this muscle was in the form of two plexuses, a superior one, most often (93%) formed by the union of the temporal and superior zygomatic branches, and an inferior one, usually formed (63%) by the union of the inferior zygomatic and superior buccal branches.

[Treatment of vesicovaginal fistulas using the musculofascial flap of the levator ani muscle: 26 case reports].

Objective: The authors reported the preliminary results of levator ani muscle flap in the treatment of vesicovaginal fistula.

Materials And Methods: Twenty-six patients whose age varied between 13 and 18 years (mean: 30 years) are selected. All the patients are treated by the vaginal approach using the part of superficial rectal fibers of the levator ani muscle.

[Anatomic study of pelvic urethra in women: value of its conservation in radical cystectomy].

The vascularization of the different layers of the pelvic urethra was studied in 12 females urethras, in which the vascular system was injected with gelatinous inda ink. The arterial vascularization of the striated muscle is essentially tributary of the sub-mucosal network by the intermediary of fascicular and interfascicular arteries which anastomose to form an intermuscular plexus. This plexus also anastomoses with the subserosal network.
