Hemangiosarcoma of the Heart

Cardiac hemangiosarcoma

Også kjent som: Cardiac Hemangiosarcoma, Cardiac HSA, Right Atrial Hemangiosarcoma

VeterinærgodkjentCatDogHaster: EmergencyHvor vanlig: Rare

Kort fortalt

Cardiac hemangiosarcoma is a highly aggressive, life-threatening cancer of the blood vessels in the heart. Primarily affecting dogs and occasionally cats, it often leads to sudden internal bleeding, fluid accumulation around the heart, and acute collapse. Understanding the symptoms, diagnostic process, and treatment options can help you make informed decisions during a medical crisis.

Anatomy of a dog's heart showing a tumor on the right atrium and fluid in the pericardium.
Cardiac hemangiosarcoma typically develops on the right atrium, leading to fluid accumulation within the pericardial sac.

TL;DR. Svært aggressiv karsvulst i hjertet: plutselig blødning, tamponade, akutt. Forsiktig prognose.

Ofte høyre atrium; blod i perikard.

Hva er det?

Ondartet endotelcelletumor. Hos hund ofte høyre atrium/aurikkel. Ruptur fyller perikard og kan gi tamponade.

"The age distribution of cats with cardiac tumors is different from that of dogs; about 28% are 7 years old or younger. It is unknown whether reproductive status affects relative risk for cardiac tumors in cats."

Årsaker og risikofaktorer

Årsak ukjent; genetisk disposisjon. Middelaldrende til eldre hunder. Ved hjertemasse også milt og lever.

"Approximately 50% of the tumors originate in the spleen, 25% in the right atrium, 13% in subcutaneous tissue, 5% in the liver, 5% in the liver-spleen-right atrium, and 1% to 2% simultaneously in other organs (i. e. , kidney, urinary bladder, bone, tongue, prostate)."

Tegn å se etter

Vanlige

  • Kollaps; synkope; svakhet; bleke slimhinner; arytmier; dempede hjertetoner; høyresidig svikt; blodstatusavvik

Av og til

  • Ascites; akantocytter; bilyd

A lethargic dog resting on the floor, representing sudden weakness and pale gums.
Plutselig svakhet og bleke slimhinner advarer om blødning fra hjertesvulst.

Diagnostikk

  • Undersøkelse: dempede toner, svake pulser, bleke slimhinner
  • Ekkokardiografi: primært verktøy

"Echography reveals an intrapericardial cystic mass compressing the cardiac cavities. However, this echographic aspect can be similar to that of a cardiac hemangiosarcoma..."

  • Cytologi av perikardvæske: ofte ikke definitiv

"An additional problem with effusions is that they frequently contain reactive mesothelial cells that may resemble neoplastic cells, leading to a false-positive diagnosis of HSA. In general, a presumptive clinical or cytologic diagnosis of HSA should be confirmed histopathologically, if feasible."

  • Blodstatus, troponin I, røntgen, buk-UL; histopatologi

A veterinarian using an ultrasound probe on a dog's chest to perform an echocardiogram.
Ekkokardiografi viser masse og væske.

Behandling

Akutt stabilisering

Perikardiocentese avlaster tamponade.

Kirurgi

Aurikkelreseksjon og/eller partiell perikardektomi (palliativ).

Kjemoterapi (VAC)

Vincristine, Doxorubicin, Cyclophosphamide

"Sixty-seven dogs with HSA in different anatomic locations were evaluated retrospectively. All dogs received the VAC protocol, as adjuvant to surgery ( n = 50), neoadjuvant ( n = 3), or as the sole treatment modality ( n = 14). There was no signi ficant difference between the MST [median survival time] of dogs with stage III ( n = 25; 195 days) and stage I/II ( n = 42; 189 days) HSA..."

Støtte

glucocorticoids palliativt mulig.

Prognose

Uten behandling: ofte dager-uker. Kirurgi + VAC: median ~189-195 dager. Katt: begrensede data.

Forebygging

Ingen kjent forebygging. Screening-ekko hos risikoraser i middelalder.

Når ringe veterinæren

Akutt:

  • Plutselig kollaps; ekstrem svakhet; bleke/blå slimhinner; alvorlig åndenød; synkope; akutt bukhevelse
