128 OVA RIO TOMY TN THE BITCH. 



large measure. Should the distal cornu be ruptured and 

 with its ovary drop away from the operator, it becomes nec- 

 essary to turn the animal over and make a second incision 

 on the opposite side, somewhat further forward. When the 

 second cornua has been secured draw it out as far as practica- 

 ble and holding it tense insert an index finger along it until 

 the ovary is reached, which is recognized by its slightly 

 greater size and density succeeding the brief neck represent- 

 ing the Fallopian tube between the end of the cornu and 

 ovary, while beyond it can be felt the ovarian ligament. 

 Engage the ligament between the end of the index finger 

 and the abdominal wall, and with a firm and vigorous move- 

 ment, using the finger end and nail as a curette, rupture 

 the ovarian ligament by drawing the finger toward the in- 

 cision, and with the aid of tension upcku the cornu draw the 

 ovary out through the abdominal incision and divide the 

 broad ligament as before. Remove the cornua with the 

 attached ovaries by rupturing them transversely near the 

 bifurcation by means of linear tension. 



If the bitch be pregnant and especially if far advanced the 

 uterine coronua will lie upon the abdominal floor, much en- 

 larged and very much more flaccid than the nongravid uterus 

 and feeling very much like intestines. The change in the 

 position of the uterus has cau.sed the unfolding of the dupli- 

 cature of the broad ligament so that it no longer covers the 

 cornu. In such cases the operation is performed in the same 

 way except that rupturing the blood vessels by linear ten- 

 sion does not insure against hemorrhage and it is necessary 

 to ligate the ovarian and uterine arteries with catgut or silk. 

 In cases of pregnancy the entire cornua should be drawn 

 out and a stpng ligature placed around the uterus or vagina; 

 and the ovaries, uterine cornua and their contents be re- 

 moved en masse. Release the upper posterior limb and close 

 the cutaneous wound by a continuous suture. 



Dangers. Rupture of the uterine cornu alluded to above.
