Retalho de padrão axial toracodorsal para correção de defeito extenso após excisão de histiocitoma fibroso maligno em canino relato de caso / Axial pattern thoracodorsal flap for treatment of large defect after malignant fibrous histiocytoma resection in a dog - case report

Os retalhos de pele em padrão axial toracodorsal são utilizados em cães para reconstruções do membrotorácico que envolvam desde a região média até a distal do antebraço. Relata-se um caso de excisão de histiocitoma fibroso maligno e reconstituição cirúrgica por meio do retalho supracitado em membro torácico de canino. Foram observadas como complicações edema, infecção, drenagem de líquido transparente da extremidade distal do membro através da interface pele-enxerto, seromae necrose parcial na região do olécrano e distal do retalho. Contudo, a maior parte do flape apresentou adequada cicatrização no leito receptor e o aspecto cosmético foi considerado satisfatório. Aos 40 dias de pós-operatório o animal veio à óbito subitamente. Na necropsia, observou-se miosite necrossupurativa nos membros posteriores em consequência de trombos oriundos de feocromocitoma maligno originário da adrenal direita.AU

Thoracodorsal axial pattern skin grafts are used in dogs for forelimb reconstructions involving since middleup to distal forearm regions. This paper reports a case of malignant fibrous histiocytoma excision in canine forelimb and its surgical reconstruction using thoracodorsal flap. The complications observed are swelling, infection, drainage of clear fluid from the distal limb through the skin-graft interface, seroma and partial flap necrosis. However, most flap area provided adequate healing in the receptor site and its cosmetic appearance was satisfactory. The animal sudden died in the 40th postoperative day. The necropsy showed necrosuppurative myositis in the hind limbs as a result of thrombus originating from a right adrenal malignant pheochromocytoma.

Prostatectomia radical com sutura de Van Velthoven na herniorrafia perineal de canino / Radical Prostatectomy with Van Velthoven Suture to Canine Perineal Herniorrhaphy

Background: Prostatectomy excision is indicated for patients with neoplasm, trauma or recurrent prostatic abscess; Van Velthoven suture have been used in urethrovesical laparoscopic anastomosis in humans. This report aimed to describe the use of Van Velthoven suture after excisional prostatectomy in a canine, which suffered partial loss and deformation of the urinary bladder after complications of perineal hernia. Case: A thirteen-year-old male dog presented dyschezia, hypophagia and had increased water ingestion; furthermore, owner verified a swelling lateral to the anus. On clinical examination it was observed left perineal hernia with incarcerated content, and peritonitis was diagnosed by ultrasonography exam. Antimicrobial and fluid therapy were initiated, and one day after the patient was referred to surgery. Through perineal access was observed retrofl exed urinary bladder partially necrotic and multiple prostatic cysts; due to great extent of the necrotic urinary bladder, associated with impossibility of complete necrotic bladder tissue removal, prostate and urinary vesicle were placed in the peritoneal cavity. It was proceeded hernia reconstruction using polypropylene mesh and monofilament nylon suture. Through median celiotomy, the bladder necrotic tissue was removed; due to hemodynamic patient instability, the total prostatectomy that was initiated was postponed, performing cystopexy and cystostomy with Foley catheter. The prostatectomy was performed at the 21st day. In that time, prostatic urethra stenosis was observed. After probing urethral repair points in the pelvic urethra and urinary bladder, the prostate was resected and was applied a Van Velthoven suture. Omentalization of the anastomotic site was done before cavity washing with NaCl 0,9%. The abdominal access was closed in three layers. The patient remained probed for six days, and after this bladder compression was initiated. After 21 days of the second operative intervention, it was necessary to correct a perineal hernia in the opposite side; reconstruction was performed by mobilizing obturator internus muscle. Discussion: In many cases of perineal herniation it was observed prostatic hypertrophy and cysts, as observed in our clinical case. After castration, prostate involutes in two or three weeks, and occur clinical signs reliefs. But the patient related shows presence of urethral stricture, helding an excisional prostatectomy. After excision of the prostate, special attention should be given to the anastomosis between urinary bladder and urethra. With the circular Van Velthoven suture was observed low incidence of bladder contraction in humans, condition which could lead to, among other things, urinary incontinence. It was observed easy and speed of execution of the technique as well as obtaining an anastomosis without tension and adequate to anastomosis healing, as well appropriated patient recovery. We concluded that Van Velthoven suture is effective to prostatectomy in dogs and that the perineal hernia may be associated with several complications that could be adequately treated by surgery.

Cistolitectomia videolaparoscópica para a remoção de múltiplos urólitos em cão pinscher obeso Relato de caso / Videolaparoscopic cystolitectomy for multiples urolith removal in obese pinscherdog Case report

A cistotomia é o procedimento mais comumente realizado no trato urinário de animais de companhiapara a remoção de cálculos vesicais, podendo ser executada por diferentes acessos. Considerando osnumerosos benefícios que a cirurgia laparoscópica apresenta em relação à cirurgia convencional, opresente relato descreve o caso de um canino fêmea, Pinscher, de 5,1kg que apresentava múltiploscálculos vesicais, no qual se realizou o diagnóstico, e o posterior tratamento, através de cistolitectomiavideolaparoscópica. Para o procedimento cirúrgico foram utilizados três portais (dois de 10mme um de 5mm) dispostos na linha média ventral e nas paredes abdominais direita e esquerda. Apósa remoção dos urólitos, obteve-se a cistorrafia por meio de sutura intracorpórea em duas camadas, aprimeira em padrão contínuo simples, e a segunda em Lembert contínuo. As litíases foram retiradasda cavidade abdominal através do acesso do segundo portal com o auxílio de um dedo de luva. Nãoocorreram complicações trans ou pós-operatórias. O presente relato demonstra que a cirurgia laparoscópicapode ser utilizada com sucesso na terapêutica de múltiplos cálculos vesicais em cães depequeno porte e obesos.(AU)

Cystotomy is the most commonly procedure performed in the urinary tract of small animals for theremoval of bladder stones, which can be performed by different approaches. Considering the numerouslaparoscopic surgery benefits, this report describes the case of a eight-years-old female DobermanPinscher, weighing 5.1 kg with multiple bladder stones. The diagnosis and subsequent treatmentwere done by laparoscopic cystolitectomy. For the surgical procedure was used three portals (two10mm and one 5mm) localized in the ventral midline and the right and left abdominal wall. After theuroliths removal, the cistorrafy was done in two layers. The first one was done by simple continuouspattern, and in the second in continuous Lembert. The urolithis were removed from the abdominal cavity by the second portal access using a glove finger. The postoperative period was uneventful. Thisreport demonstrates that the laparoscopic surgery can be successfully used in the treatment of multiplebladder stones in small obese dogs.(AU)
