VASCOLARIZATION SPLEEN
CELIAC (UNPAIRED)
3 BRANCHES: HEPATIC, LEFT GASTRIC, SPLENIC
SPLENIC GIVE RAISE UP TO 3 PANCREATIC ARTERIES AND 1-2 LONG VESSEL SHORT GASTRIC
CONTINUATION SPLENIC GASTROEPIPLOIC
SPLEEN RESEVOIRS
90% BLOOD RAPID POOL. 30 SEC
9% INTERMEDIATE, 8 MINUTES
1% SLOW, 1 HOUR
SPLENITIS
BACTERIAL, VIRAL, FUNGAL, PROTOZOAL
CATS WITH EOSINOPHILIC SYNDROME OR DOGS WITH EOSINOPHILIC GASTROENTERITIS MAY PRESENT EOSINOPHILIC SPLENITIS.
PYOGRANULOMATOUS SPLENITIS IN CATS WITH FIP
DIC WITH TROMBOSIS AND CLOSTRIDIUM SEEDING
4 CAUSES OF SPLEEN CONGESTION
CONGESTIVE HEART FAILURE
PORTAL HYPERTENSION
VASCULAR OUTFLOW OBSTRUCTION
CAPSULAR RELAXATION TO CHEMICAL STIMULI (BARBITURICI, FENOTIAZINE..)
DIFFERENCE DOG CAT SPLEEN
DOG HAS SINUSOIDAL SPLEEN CAN NONSINUSAL
CAS IS LESS PRONE TO SEVERE SPLENOMEGALY IN COMPARISON TO DOGS
LOCALIZED FORMS OF SPLENOMEGALY
1) NODULAR HYPERPLASIA (SPLENIC FIBROHISTIOCITIC NODULES IS A HISTOLOGICALLY DISTINCT TYPE OF NODULAR HYPERPLASIA)
2) PSEUDOTUMOR
3) HEMANGIOMA
4) HAMARTOMA
5) ABSCESS
6) CYST
7) SEGMENTAL INFARCTION
8) PLAQUES
9) NEOPLASIA
CAT SPLEEN CAN BE FOLDED OVER ITSELF AND APPEAR BIGGER?
FALSE, IT’S RARE TO SEE CATS SPLEEN FOLDED. MORE COMMON IN DOGS
CEUSS DOG SPLEEN
MALIGNANT LESIONS: MORE HYPOECHOIC DURING EARLY AND LATE VASCULAR PHASES
BENIGNANT: ISOECHOIC IN LATE VASCULAR PHASE
FNA FOR SPLEEN DIAGNOSTIC: USEFUL??
GOOD FOR HEMATOPOIETIC NEOPLASIA AND HYPERPLASIA (READY CELLULAR EXFOLIATION)
NON DIAGNOSTIC OFTEN IN TRAUMA, TORSION, VASCULAR DISORDERS, FIBROSIS, LYMPHOID ATROPHY, AMILOIDOSIS
WHAT VESSELS HISTORILACCY WERE PRESERVED FOR SPLENECTOMY?
LEFT GASTROEPIPLOIC AND SHORT GASTRIC. IN FACT, IS NOT REALLY NECESSARY TO PRESERVE THESE VASCULAR STRUCTURES FOR GASTRIC BLOOD FLOW.
WHAT VESSELS HISTORILACCY WERE PRESERVED FOR SPLENECTOMY?
LEFT GASTROEPIPLOIC AND SHORT GASTRIC. IN FACT, IS NOT REALLY NECESSARY TO PRESERVE THESE VASCULAR STRUCTURES FOR GASTRIC BLOOD FLOW.
PCV VALUES TO DIAGNOSE HEMATIC PERITONEAL FLUID
HIGHER THAN PERIFERAL BLOOD IS SUPPORTIVE OF DIAGNOSIS OF HEMATIC LOSS
SPLENIC TORSION SYMPTOMS AND HEMATOLOGIC FINDINGS
LETARGY, ANOREXIA, VOMITING, DHIARREA, PU-PD, WEIGHT LOSS, DISCOLORED URINE
LEUKOCITOSIS, ANEMIA, TROMBOCITOPENIA
DIAGNOSIS AND MANAGEMENT SPLENIC TORSION
COLOR DOPPLER HILUS ULTRASONOGRAPHY
NO DEROTATION OF THE SPLEEN HILUS!
