Accidents of Gestation: Hydrops Allantois
Hydrops Allantois in a Holstein Cow.
Bilateral distension of the abdomen due to hydrops allantois.
Roberts SJ (1973)
Hydrops Allantois in an Angus Cow.
Bilateral symmetrical distension of the abdomen due to hydrops allantois in an Angus cow. By contrast, bloat is manifested by left lateral distension of the abdomen only and the profile of a cow with hydramnios is pear-shaped.
Drost M (2008)
Hydrops Allantois in an Angus Cow.
Bilateral symmetrical distension of the abdomen due to hydrops allantois in an Angus cow. By contrast, bloat is manifested by left lateral distension of the abdomen only and the profile of a cow with hydramnios is pear-shaped.
Shipley C (2006)
Hydrops Allantois.
Rear view of a cow with hydrops allantois. Notice bilateral distension of the abdomen. Abdominal circumference: 2.65 m.
Utrecht (1976)
Recumbent Cow with Hydrops Allantois.
Recumbent cow essentially unable to stand due the excessive weight of the allantoic fluid. The cumulative weight of the fetal fluids, fetal membranes and uterus may be as much as 150 to 250 kg.
Roberts SJ (1973)
Hydrallantois Profile.
Bilateral distention of the abdomen due to hydrops allantois. This should be differentiated from a similar distension due to twins or triplets. If the uterus is tightly distended the diagnosis is hydrops allantois, if fetal parts can be identified it is not.
Roberts SJ (1973)
Hydrops Allantois Profile.
Bilateral distention of the abdomen due to hydrops allantois. This should be differentiated from a similar distension due to twins or triplets. If the uterus is tightly distended the diagnosis is hydrops allantois, if fetal parts can be identified it is not.
Prado TM (2007)
Hydrallantois Profile After Induction.
Bilateral abdominal distension due to hydrops allantois is gone after induction of parturition and expulsion of the excessive fluids and the fetus.
Roberts SJ (1973)
Grossly Distended Hydrallantoic Uterus.
This cow was initially misdiagnosed as suffering from bloat, despite the fact that her abdomen was bilaterally distended. It was not possible to ballot a fetus through the tightly distended uterine wall.
Roodzant JP (2007)
Postmortem View of Hydrallantois.
This cow was initially misdiagnosed as suffering from bloat, despite the fact that her abdomen was bilaterally distended. It was not possible to ballot a fetus through the tightly distended uterine wall.
Roodzant JP (2007)
Tightly Distended Uterus due to Hydrallantois.
This postmortem specimen shows a tightly distended uterus due to hydrallantois. No fetal parts are palpable through the taut, stretched wall. Notice the postmortem (no hemorrhage) split in the perimetrium.
Roberts SJ (1973)
Normal Cotyledons.
Normal third trimester (fetal) cotyledons as separated from the (maternal) caruncle.
Drost M (1978)
Early Adventitious Placentation.
Small adventitious specks can be seen next to normal cotyledons.
Drost M (1978)
Severe Adventitious Placentation.
Multiple random islets of cotyledonary tissue surround a normal cotyledon. Adventitious placentation can lead to placental dysfunction and result in hydrallantois.
Roberts SJ (1973)
Allantocentesis - Local Anesthesia.
Local anesthesia of the site of placement of the trocar for a second allantocentesis in a cow with hydrops allantois.
Utrecht (1976)
Allantocentesis - Skin Incision.
After surgical preparation and administration of local anesthesia, a small skin incision is made prior to the placement of the trocar for slow drainage of the allantoic fluid of a cow with hydrallantois.
Utrecht (1976)
Allantocentesis - Insertion of the Trocar.
Placement of the trocar in lower right flank of a cow with hydrops allantois to drain excessive allantoic fluid.
Utrecht (1976)
Hydrallantois - Allantocentesis.
Clear, urine-like allantoic fluid flowing from the trocar during allantocentesis.
Utrecht (1976)
Hydrops Allantois - Allantocentesis.
Cannula placement in the lower righthand quadrant of the abdomen after surgical preparation of the area (by Dr. Gerrit Schuijt).
Utrecht (1976)
Allantocentesis - Fluid Collection.
Free flowing clear allantoic fluid during in allantocentesis in a cow with hydrops allantois, under the watchful eye of Dr. Gerrit Schuijt.
Utrecht (1976)
Allantocentesis - Skin Suture.
Placement of a skin suture after withdrawal of the cannula (second allantocentesis).
Utrecht (1976)
Allantocentesis - Placement of a Suture.
One skin suture is placed following the withdrawal of the cannula.
Utrecht (1976)
Hydrops Allantois in a Near Term Ayrshire Cow.
Extreme bilateral distension of the abdomen due to hydrallantois in a near-term Ayrshire cow.
Wright JM (1973)
Hydrops Allantois Profile after Induction of Parturition.
Parturition was induced with glucocorticoids in this Ayrshire cow that suffered from hydrallantois.
