Study of pulmonary arterial flow in the transplanted lung by means of an implanted ultrasonic flowmeter enables us: 1. To confirm results obtained by other methods (De Bono,8 Strider14 and Strandberg18): without specific treatment, rejection of graft causes increased peripheral resistances and the pulmonary arterial flow decreases progressively. 2. To prove by direct observation the existence in the treated animal of authentic precapillary shunts whose importance can cause the animal's death through functional disorder alone.

Posttraumatic Stress Disorder Is Associated With Endothelial Dysfunction in Women With HIV.
JACC Adv
January 2025
Department of Psychiatry and Behavioral Sciences, Emory University, Atlanta, Georgia, USA. Electronic address:
Background: HIV induced endothelial dysfunction (ED) contributes to cardiovascular disease (CVD) in women with HIV (WWH). Although psychosocial stress has been implicated in the development of CVD in HIV, its impact on ED in WWH remains unknown.
Objectives: The authors hypothesized that posttraumatic stress disorder (PTSD) and HIV interact to contribute to ED in WWH.
Retrograde thrombosis of the superficial sylvian vein following liquid adhesive hemostat use during craniotomy: illustrative case.
J Neurosurg Case Lessons
January 2025
Department of Neurosurgery, University of California, Irvine, Orange, California.
Background: Intravascular injection of liquid adhesive hemostats is a rare but serious complication that can result in cerebral thromboembolism.
Observations: A 64-year-old female underwent orbitozygomatic craniotomy for posterior communicating artery aneurysm clipping with the routine use of a flowable hemostatic agent during extradural dissection. After placement of the aneurysm clip, flow was confirmed through the parent vessel and nearby branches.
Recurrent thrombus formation in a carotid web: highlighting the importance of timely surgical intervention. Illustrative case.
J Neurosurg Case Lessons
January 2025
Department of Neurosurgery, Institute of Medicine, University of Tsukuba, Tsukuba, Ibaraki, Japan.
Background: Carotid webs are rare nonatherosclerotic disorders in the carotid artery and are increasingly recognized as factors of ischemic stroke in the young population. Asymptomatic webs can be treated with antithrombotic therapy, whereas symptomatic cases frequently require surgical interventions, including carotid endarterectomy (CEA). However, guidelines for the optimal timing of these treatments remain unestablished, especially compared to atherosclerotic stenotic lesions, due to the rarity of carotid webs.

Ann Nucl Med
January 2025
Turku PET Centre, University of Turku and Turku University Hospital, Turku, Finland.
Dynamic positron emission tomography (PET) can be used to non-invasively estimate the blood flow of different organs via compartmental modeling. Out of different PET tracers, water labeled with the radioactive O isotope of oxygen (half-life of 2.04 min) is freely diffusable, and therefore, very well-suited for blood flow quantification.

Neth Heart J
January 2025
Department of Cardiology, Leiden University Medical Centre, Leiden, The Netherlands.
Objectives: Coronary graft failure (CGF) may occur early after coronary bypass graft surgery (CABG). The study aimed to identify clinical and perioperative risk factors and to evaluate the long-term clinical impact of symptomatic early CGF.
Methods: Patients who underwent clinically indicated coronary angiography (CAG) prior to post-CABG discharge between 2012 and 2022 were included.
