Multiple persistent vitelline duct cysts in a dog.

Persistent vitelline duct remnants, with the exception of Meckel's diverticulum in pigs and horses, are rare in animals. During an ovariohysterectomy of an 8-month-old Labrador Retriever, multiple fibrous nodules with cystic centers were found attached to the ileal serosa and in a mesodiverticular band attached to the abdominal wall. Histologic and ultrastructural evaluation revealed that the cysts were composed of well-differentiated intestine with mucosa, submucosa, and muscularis layers surrounded by a thick layer of fibrous connective tissue. The morphology and arrangement of lesions were consistent with multiple persistent vitelline duct cysts, a distinct condition related to Meckel's diverticulum. This case in a dog represents a unique presentation of this congenital anomaly in domestic animals.

Remnants of vitelline duct: analysis of 66 cases.

In twenty years, 66 infants and children with remnants of vitelline duct requiring surgery have been admitted. The patients were classified into three groups: patient vitelline duct (20 cases); Meckel's diverticulum as the primary surgical diseases (19 patients); and Meckel's diverticulum found incidentally at surgery (27 patients). The male preponderance in the groups of patent vitelline duct and symptomatic Meckel's diverticulum was 9:1. In contrast with other data, Meckel's diverticulum requiring surgery occurred with nearly equal frequency up to fourteen years. The gravest complication in the cases of patent vitelline duct were a T-shaped protrusion of ileum and a small bowel volvulus around the fibrous cord or the patent duct; and in the cases of Meckel's diverticulum causing symptoms, intestinal obstruction, bleeding peptic ulceration or inflammation. Three deaths occurred in newborn age in connection with patent vitelline duct, and one patient died who belonged to the group of asymptomatic Meckel's diverticulum.

[Intra-abdominal ligament remnants of the vitelline duct and vessels].

Intraabdominal bands of the vitelline vessels and vitelline duct are discovered as a congenital disturbance any time in life. In more than 75% they cause an acute abdominal disease. In this paper we discuss the cause and the clinical picture in 19 children seen in our department together with 83 cases from the literature. In 70% of the cases we find remnants of the right and left vitelline artery, in a third remnants of the vitelline vein and vitelline duct. The characteristic course is the acute strangulation of the intestine with gangrene of the bowel and endotoxine shock. The best treatment in every case is the operation as soon as possible.

Vitelline duct anomalies. Experience with 217 childhood cases.

Of 217 children with vitelline duct anomalies, 85 (40%) had symptomatic lesions (mean age, 2.4 years). Forty-eight patients presented with rectal bleeding; 28, with intestinal obstruction; five, with abdominal pain; and four, with bilious umbilical drainage. An asymptomatic Meckel's diverticulum was discovered incidentally at laparotomy in 132 children. Surgical therapy included bowel resection in nine patients with volvulus, four with intussusception, seven with bleeding, three with vitelline cysts, and one with a perforation. Diverticulectomy was performed in 189 cases, and excision of a patent vitelline duct was accomplished in four neonates with umbilical drainage. Ectopic gastric mucosa was present in all 48 patients with bleeding and in four of five with inflammation but in only two asymptomatic specimens. More than one third of the cases were symptomatic and presented in younger patients. This suggests that elective resection of asymptomatic vitelline remnants in early childhood is reasonable at the time of laparotomy for other conditions.

Patent vitelline duct in an adult deceptively appeared to be acquired umbilical urachal sinus: a case report.

Here is presented a surprisingly rare case in a 40-year-old male who had patent vitelline duct by nature. However, his congenital disease appeared deceptively to be an acquired umbilical urachal sinus on the diagnostic evaluations including fistulography before surgery. The diagnosis was definitely confirmed after the successful surgical procedure. The principal reason why these diseases were indistinguishable was reviewed. The incidence of each disease and incidence of association with umbilical fistula in each disease were discussed. With regard to these incidences, we compared urachal anomalies with vitelline duct anomalies through reference of several literatures. This is the most unique event we have ever clinically experienced.

Umbilical core-out operation for a completely patent vitelline duct.

An umbilical core-out operation for a completely patent vitelline duct in a premature baby with successful preoperative manual reduction of the prolapsed ileal loops is described. In certain cases with this rare anomaly this procedure can be applied. The procedure is easy, timesaving, bloodless and necessitates no laparotomy incision.

Vascularization of yolk sac and vitelline duct in normal pregnancies studied by transvaginal color and pulsed Doppler.

The yolk sac is an organ of increasingly recognized importance in the initial mechanisms of pregnancy maintenance and the early growth and welfare of the embryo. Having a complex protein secretion and an equally intricate ultrastructure, it is the primary source of blood and germ cells. This small and to date largely ignored structure may have a vital and interesting part to play in human embryonic development, which may be comparable to its proven evolutionary importance in other animals. The aim of our study was to assess the vascularity of the yolk sac and vitelline duct in 105 patients between the 6th and 10th weeks of gestation who were scheduled for termination of pregnancy for psychosocial reasons. The patients were divided in five subgroups depending on the duration of gestation. All of them had a normal developing pregnancy with no clinical symptoms of pathology (e.g. bleeding in early pregnancy). Gestational age was calculated from the first day of the last menstrual period and substantiated by crown-rump (CRL) measurements. After exploration of the gestational sac and embryo by transvaginal sonography, color Doppler was used to image the yolk sac and vitelline duct vascularity. The visualized vessels were analyzed with pulsed Doppler using the sample volume unit set of 1 mm. The assessment of obtained waveform signals was made by means of peak systolic Doppler shift (PSV) and pulsatility index (PI). The pulsatility index was calculated as a difference between peak systolic and end diastolic Doppler shift divided by the mean maximum velocity. At least 5 separate cardiac cycles were measured, and the mean value was calculated.(ABSTRACT TRUNCATED AT 250 WORDS)

Ascending colon volvulus due to a vitelline duct remnant in an elderly patient.

A 77-year old female is presented with volvulus of the ascending colon due to torsion around a vitelline duct remnant. Symptoms were mild and intermittent. Roentgenograms are presented which demonstrated this lesion preoperatively. At surgery the ascending colon was found to be twisted around a fibrous band extending from the umbilicus to the ileum.

A case of Ehlers-Danlos syndrome (type IV) with persisting vitelline duct cyst.

A twenty-four year old white man with Ehlers-Danlos syndrome (Type IV) is presented herein. He demonstrates, or has demonstrated, spontaneous bowel perforation, club feet, cryptorchidism, spontaneous vascular rupture, prominent veins, and distal joint hypermobility. In addition, laparotomy for an acute abdominal condition at four years of age revealed a persisting and gangrenous vitelline duct cyst. We believe this is the first report of this congenital anomaly associated with this syndrome.
