Patients with splenic torsion can have vague clinical signs that may include abdominal pain, weakness, hypotension, tachycardia and collapse 9. Splenic torsion can occur as a rare primary condition in dogs, or in association with gastric dilation and volvulus (GDV). The presence of a hilar hyperechoic perivenous triangle was significantly associated with splenic torsion (P=0.005). The pathogenesis associated with splenic torsion remains undetermined; however, large breed, deep-chested dogs appear to be at an increased risk with males being affected more frequently than females (9,10). This paper describes a case of chronic primary splenic torsion in a female Great Dane. The presence of a hilar hyperechoic perivenous triangle was significantly associated with splenic torsion (P … (B) Sagittal ultrasound image of a dog with a splenic torsion. 1. 36(5), 390-394. 2003 Sep-Oct;44(5):553-5. This is a modal window. The dorsal head is close to the stomach and fixed in position. A veterinarian can diagnose splenic torsion based on physical findings, laboratory tests, x-rays and ultrasounds. The mass was revealed to be spleen on ultrasonography. The splenic lesion appeared as an anechoic perfusion defect area with an unclear irregular border (red arrows), suggesting the absence of active bleeding. PMID: 14599168 Given the concern for an abdominal issue, the emergency clinicians recommended an abdominal ultrasound. The ultrasound revealed changes that indicated splenic swelling and loss of splenic blood flow. It also showed free fluid in the abdomen, and enlarged lymph nodes around the abdominal area. In the present case, abdominal ultrasound findings were consistent with splenic torsion. Imaging diagnosis: the abdominal air-vasculogram in a dog with splenic torsion and clostridial infection. In the remaining dog, the spleen was derotated and left in place. With a splenic torsion, the dog is in a lot of pain and you know it’s coming from the abdomen somewhere. SPLENIC TORSION. ... Computed tomography diagnosis of isolated splenic torsion in a dog. The presence of a hilar hyperechoic perivenous triangle was significantly associated with splenic torsion (P=0.005). Diseases of the spleen, from Hemangiosarcoma to Splenic Torsion, are serious concerns in the Greater Swiss Mountain Dog. The torsion cuts off blood flow to the area where it occurs, resulting in a painfully enlarged spleen. Splenic torsion occurs when the blood supply to the spleen twists on itself (Figure 1). Image of the spleen from a dog in traumatic hemorrhagic shock. This is a modal window. Laboratory tests include a complete blood count, electrolyte and chemical profile, urinalysis and coagulation test. Symptoms of Splenic Torsion in Dogs The symptoms of splenic torsion in dogs will vary depending on whether it is acute or chronic. Acute nontraumatic hemoabdomen in the dog: a retrospective analysis of 39 cases (1987-2001). Splenomegaly was also evident on abdominal ultrasonography and radiology in most dogs. Splenic Mass in a Beagle. In a group of animals where acute splenic torsion was part of the ultrasound report differential diagnosis, we compared findings in dogs with torsion with findings in dogs with other splenic conditions. Video Player is loading. Marked splenomegaly with diffuse lacey pattern and splenic thrombi are present in this torsed spleen. Splenic torsion is more common in large-breed, deep-chested dogs, such as the Great Dane, German shepherd dog, and … J Am Vet Med Assoc 2011;239:1325-7. Weber NA. Med. Splenic Torsion is a twisting, or folding and unfolding of the spleen. A hyperechoic hilar perivenous triangle (blue arrows) is seen, and the splenic vein (orange arrow) does not demonstrate blood flow on color Doppler interrogation (yellow box). PUBMED Abstract; Saunders HM, Neath PJ, Brockman DJ. Spleen issues are also more common in dogs five years of age and older though we have seen them in younger dogs. diagnosis of isolated splenic torsion in a dog. In a group of animals where acute splenic torsion was part of the ultrasound report differential diagnosis, we compared findings in dogs with torsion with findings in dogs with other splenic conditions. It may occur by itself (rare, except in GSMDs) or in association with gastric dilatation-volvulus (GDV) syndrome, commonly known as bloat. The clinical, radiographic, and sonographic signs in three dogs with splenic torsion are presented. Large and giant breed dogs with a deep-chested conformation (e.g., Great Danes and German Shepherds) are most commonly affected. Several risk factors for death prior to discharge were identified, including preexisting septic peritonitis, intraoperative hemorrhage, and postoperative development of respiratory distress. This dog had splenic torsion and was PCR positive for L. infantum; both conditions might have triggered splenitis because of altered vascularity and blood supply or activation of the reticuloendothelial system and likely caused anemia. A diagnosis was obtained by radiography and ultrasound. Vet Radiol Ultrasound. Splenic torsion in dogs can be defined as a twisted spleen, a life-threatening condition in which blood flow is cut off, resulting in swelling and pain in the abdominal area. Non-invasive, in many cases sedation not required and rare to require anesthesia. B-mode and Doppler ultrasound imaging of the spleen with canine splenic torsion: a retrospective evaluation. Splenic torsion occurs when the spleen rotates around the blood vessels entering the spleen or twists upon itself, thereby decreasing blood flow to the spleen. They seem to be more common in large breed dogs, particularly splenic torsion. The spleen can store 10% to 20% of a dog’s RBC mass and 30% of the platelet mass. Although ultrasound was able to identify multiple abdominal masses and lymphadenopathy, CT verified that the masses were of testicular origin. Torsion may occur as an isolated event or in conjunction with gastric dilation and volvulus (stomach bloat-ing and twisting). Both dogs were diagnosed with chronic splenic torsion based on changes in splenic position, echogenicity, and/or echotexture identified on B-mode abdominal ultrasonography, as well as either decreased or absent splenic blood flow on color-flow Doppler ultrasonography. Pintar J, Breitschwerdt EB, Hardie EM, Spaulding KA. Splenectomy was performed in all but 1 of the dogs included in the review. Saunders HM, Neath PJ and Brockman DJ. (2000). Imaging Diagnosis: The Abdominal Air-Vasculogram in a Dog with Splenic Torsion and Clostridial Infection Veterinary Radiology Ultrasound, 2003 Karin Hurter It occurs most often with gastric dilatation-volvulus (GDV). Both dogs underwent splenectomy and had full resolution of clinical signs. Large and giant breed dogs with a deep-chested conformation (e.g., Great Danes and German Shepherds) are most commonly affected. Abdominal radiographs and ultrasound are useful in confirming the diagnosis of splenic torsion. Other tests that may be required include blood work and urine analysis. DOI: 10.1111/J.1740-8261.2001.TB00931.X Corpus ID: 29411352. This is commonly seen with lymphoma. Note that the splenic parenchyma is hypoechoic and heterogeneous in echogenicity and echotexture (orange asterisk). Primary splenic torsion in dogs: 102 cases (1992-2014) Results suggested that the prognosis for dogs undergoing splenectomy because of PST was favorable. Reservoir Function. Vet Radiol Ultrasound, 42: 235-237, 2001. revealed changes that indicated splenic swelling and loss of splenic blood flow. PUBMED Abstract @article{Patsikas2001ComputedTD, title={Computed tomography diagnosis of isolated splenic torsion in a dog. Beginning of dialog window. Abdominal ultrasound, however, particularly with Doppler flow capabilities, is an excellent diagnostic tool in splenic torsion cases. This article reports on a case of splenic torsion in a female Briard breed dog focusing on its diagnosis and treatment. Vet Radiol Ultrasound 1998;39:349–53. Journal of the American Animal Hospital Association. Millis, D.L., Nemzek, J., Riggs, C., Walshaw, R., Gastric dilatation-volvulus after splenic torsion in two dogs. A successful splenectomy was performed and resulted in complete recovery of the animal. Case : An adult dog without a defined breed pattern that weighed 8.6 kg was referred to the Veterinary Hospital of the This prevents blood drainage, causing subsequent enlargement of the spleen. but can also occur in isolation. Contrast-enhanced ultrasound was performed and showed a solid hypoechoic avascular mass, which was all that remained of the spleen, located under the left kidney. Case evaluation & interpretation by “Team SonoPath.” Sonogram (Spleen): “Popeye” splenectomy was performed, and the dog recovered well without complications. (1998). J Am Vet Med Assoc, 207: 314-315, 1995. End of dialog window. This case report provides an example of how CT can aid in the diagnosis of cryptorchidism and suspected testicular torsion. Contrast-enhanced ultrasound of the spleen. Background: The splenic torsion is a rare condition in dogs, especially when it is not associated with gastric dilatation and volvulus. Splenic torsion, or twisting of the spleen, may occur by itself, or in association with gastric dilatation-volvulus (GDV) syndrome, when a dog’s air-filled stomach expands and twists on itself. It can occur suddenly, or it can gradually twist over a period of time. Dogs are rarely affected by an abnormality such as splenic torsion. Mai W. The hilar perivenous hyperechoic triangle as a sign of acute splenic torsion in dogs. This is the first report of splenic torsion in Boston ter-riers, and the usefulness of ultrasonographic and CT findings of the splenic torsion was also confirmed. KEY WORDS: Boston terrier, computed tomography, splenic torsion, ultrasonography. RBCs passing through the spleen during normal circulation are divided into three “pools,” depending on the circulatory pattern. And again, we think about the distribution of the pathology. “There have been associations between of dogs developing gastric dilatation and volvulus following splenectomy, and dogs developing splenic torsion after GDV,” explains Dr. Gleason. Both splenic torsions and GDVs are most frequently seen in large, deep-chested dogs. Splenic torsion can exhibit numerous clinical signs; here, ultrasound imaging allowed diagnosis of this condition. J. Vet. 15. In a group of animals where acute splenic torsion was part of the ultrasound report differential diagnosis, we compared findings in dogs with torsion with findings in dogs with other splenic conditions. Splenic torsion in a dog. Splenic torsion occurs when the tail of the spleen rotates around the pedicle. Isolated splenic torsion in a dog was diagnosed using computed tomography (CT). Sonogram by Andi Parkinson RDMA of Intrapet Imaging, Baltimore, MD, USA. Abdominal ultrasonography has been reported as an accurate diagnostic method in cases of splenic torsion suspicions. The other one that we might see is a Swiss cheese spleen, where there are hypoechoic holes in the spleen. Clinical signs had already been present for two weeks. Chronic primary splenic torsion with peritoneal adhesions in a dog: case report and literature review. Mass-to-splenic volume ratio and splenic weight as a percentage of body weight in dogs with malignant and benign splenic masses: 65 cases (2007-2008). A physical exam will reveal the enlarged spleen upon palpating the abdomen. Splenic Ultrasound Anatomy in Cats and Dogs “The spleen is an elongated flattened organ, which is triangular in cross section in dogs and ovoid in cats. "Findings often include generalized splenomegaly, evidence of splenic infarction, a twisted splenic pedicle, and absence of blood flow through the splenic vessels on Doppler evaluation," Boothe explained. AH dogs exhibited weight loss, anorexia, and lethargy. We speculate that this sign is associated with torsion because of the secondary severe, diffuse splenic … Splenic torsion. Author information: (1)Department of Clinical Veterinary Medicine, Division of Radiology, University of Bern, Switzerland. Vet Radiol Ultrasound 2006;47:487–91. Escape will cancel and close the window. The spleen was easily imaged sonographically in all dogs. An abnormal spleen position was detected by ultrasonography in 31.7% of the dogs but by radiology in only 7.4%. reports a case of splenic torsion followed by abdominal trauma and eventration in a dog, highlighting the importance of the ultrasound examination. 48 Blood drawn from the splenic sinus system has a very high hematocrit (80% to 90%) to accommodate this storage. Sci. B-mode and Doppler ultrasound imaging of the spleen with canine splenic torsion: a retrospective evaluation. Gaschen L(1), Kircher P, Venzin C, Hurter K, Lang J. A dog with a history of diaphragmatic hernia repair two years previously presented with chronic, vague clinical signs and an abdominal mass. It’s located near the stomach on the left side and it goes under the ribcage cranially. Splenomegaly was consistent radiographic finding in two dogs and large ill‐defined midabdominal mass was seen in one dog. Computed tomography diagnosis of isolated splenic torsion in a dog. Based on the ultrasound findings, CT scan and MRI of the abdomen were performed to confirm the suspicion of torsion of a wandering spleen.
