Obravnava ambulantnih bolnikov z ishemijo pri perfuzijski scintigrafiji srca
Kristina Arih, Jonas Podnar, Barbara Gužič-Salobir, Monika Štalc, 2025, izvirni znanstveni članek

Povzetek: Izhodišče: Ishemija srčne mišice je kompleksno dogajanje, ki pomeni za bolnika slabši izid. Perfuzijska scintigrafija srca (PSM) je neinvazivna metoda, s katero ugotavljamo prisotnost ishemije. Namen naše raziskave je bil pridobiti podatke o obravnavi bolnikov z ugotovljeno ishemijo pri PSM, saj le-teh v slovenskem prostoru doslej nismo imeli na voljo.Metode: V raziskavo smo vključili 306 ambulantno obravnavanih bolnikov, ki so jim v letu 2020 pri PSM ugotovili ishemijo. Iz baze podatkov Klinike za nuklearno medicino in iz informacijskih sistemov smo zbrali demografske, klinične in scinti-grafske podatke ter podatke o napotitvi na koronarografijo in podatke o revaskularizacijskih posegih.Rezultati: Na koronarografijo so napotili 74 % bolnikov, ki so imeli značilno več tipične prsne bolečine (40 % vs. 23 %, p=0,005) in dispneje (50 % vs. 38 %, p=0,051) kot nenapoteni bolniki. Na koronarografijo so napotili značilno več bolnikov z zmerno in hudo ishemijo kot pa bolnikov z blago ishemijo (83 % vs. 65 %, p=0,003; 93 % vs. 65 %, p<0,001) ter več bolnikov s hudo ishemijo kot tistih z zmerno ishemijo (93 % vs. 83 %, p=0,003). Pri večjem deležu bolnikov z obsegom ishemije nad 10 % je bil nato opravljen revaskularizacijski poseg (84 % vs. 61 %, p=0,036).Zaključek: Zdravniki večino bolnikov z ishemijo pri PSM napotijo na koronarografijo. Obseg ishemije je povezan z napoti-tvijo na koronarografijo in odločitvijo za revaskularizacijske posege.

Imaging of spontaneous biliary perforation in neonates : focus on ultrasound findings with a review of the literature
Maja Šljivić, Kristina Arih, Mojca Glušič, Damjana Ključevšek, 2025, pregledni znanstveni članek

Povzetek: Spontaneous biliary perforation in neonates is a rare but potentially life-threatening condition with nonspecific clinical presentation. Early diagnosis is challenging due to nonspecific clinical signs, yet it is critical for appropriate management. Our objective is to present two etiologically distinct cases of neonatal spontaneous biliary perforation and to review the literature, with a focus on imaging findings, particularly the role of ultrasound (US) in diagnosis. Abdominal US was the initial imaging modality. Indirect ultrasound signs, such as fluid collections near the gallbladder extending towards the duodenum, the porta hepatis, and further into the abdomen, gallbladder wall thickening, and bile duct abnormalities, helped raise suspicion of spontaneous biliary perforation. US findings can be nonspecific, and the direct sign – the so-called ‘hole sign’ – is rarely observed. The final diagnosis was confirmed using magnetic resonance cholangiopancreatography, hepatobiliary iminodiacetic acid scanning, and intraoperative cholangiography. A literature review was conducted focusing on the role of imaging in 23 neonatal cases of spontaneous biliary perforation reported since 1995. Ultrasound was the initial diagnostic tool in 19 cases. In eight cases (42%), US findings raised suspicion of spontaneous biliary perforation, including two cases with direct and six with indirect signs. Hepatobiliary iminodiacetic acid scanning and magnetic resonance cholangiopancreatography served as confirmatory methods. In 65.2% of cases, the diagnosis was ultimately confirmed surgically. Ultrasound plays an important role in the early diagnosis of spontaneous biliary perforation in neonates, mostly through recognition of indirect signs, highlighting the importance of familiarity with this entity
