Review
F. Mason Sones Jr. (1918-1985) was a pioneering cardiologist whose groundbreaking work revolutionized the field of cardiology. His accidental discovery of coronary angiography in 1958 at the Cleveland Clinic provided physicians with the first clear visualization of coronary arteries in living patients, paving the way for the development of coronary artery bypass surgery and interventional cardiology. This review article explores F. Mason Sones Jr.'s life and career, and his lasting impact on the field of cardiology. Born in Noxapater, MS, in 1918, F. Mason Sones Jr. attended Western Maryland College (Westminster, MD) and the University of Maryland School of Medicine (Baltimore, MD) before completing his internship and residency at the University Hospital (Baltimore, MD) and Henry Ford Hospital (Detroit, MI), respectively. After serving in the U.S. Army Air Corps during World War II, F. Mason Sones Jr. joined the Cleveland Clinic (Cleveland, OH), in 1950, as the head of pediatric cardiology, where he combined his expertise in cardiac catheterization with his interest in congenital heart disease. F. Mason Sones Jr.'s serendipitous discovery of coronary angiography occurred during a routine cardiac catheterization procedure when he inadvertently injected contrast dye directly into the right coronary artery. Realizing that smaller amounts of dye could safely opacify the coronary arteries, F. Mason Sones Jr. refined and standardized the technique of selective coronary angiography, collaborating with engineers to improve X-ray imaging and establishing protocols that remain the standard of care today. F. Mason Sones Jr.'s work provided the foundation for the development of coronary artery bypass surgery by Dr. René Favaloro and the birth of interventional cardiology, as pioneered by Dr. Andreas Gruentzig. As the director of cardiovascular disease at the Cleveland Clinic (1966-1975), F. Mason Sones Jr. mentored and inspired a generation of cardiologists, cementing his legacy as a visionary leader in the field. Throughout his career, F. Mason Sones Jr. received numerous awards and honors, including the American Medical Association's Scientific Achievement Award and the Gairdner Foundation International Award. He co-founded and served as the first president of the Society for Cardiac Angiography (now SCAI), an organization dedicated to advancing the field of interventional cardiology. This review article pays tribute to F. Mason Sones Jr.'s enduring contributions to the field of cardiology, highlighting his role as a pioneer, innovator, and mentor. His legacy continues to inspire and guide generations of cardiologists in their pursuit of improving patient care and pushing the boundaries of cardiovascular medicine.

Although intravascular atherectomy is widely used for debulking calcified atheromas in peripheral arterial disease, it is associated with complications. Delayed rupture with pseudoaneurysm formation is rare. We report the case of a 73-year-old man who developed a 24 mm×20 mm×27 mm popliteal artery (PA) pseudoaneurysm after rotational atherectomy. Initially, the patient presented with intermittent claudication. Preoperative computed tomographic angiography (CTA) showed a severely calcified atheroma in the PA. Rotational atherectomy was performed using the Jetstream™ device (Boston Scientific). Postoperatively, the ankle-brachial index and symptoms improved. However, 6 days after the atherectomy, the patient complained of calf pain and swelling. Follow-up CTA revealed a pseudoaneurysm and hematoma in the popliteal fossa. Open conversion with removal of the heavily calcified plaque and patch angioplasty were performed via the posterior approach. Delayed PA rupture and pseudoaneurysm formation after rotational atherectomy are rare; however, they require prompt management.

BACKGROUND
Pleural solitary fibrous tumors (pSFTs) are rare mesenchymal pleural tumors with rich vascularity. Surgical resection is the cornerstone of pSFTs treatment, requiring careful preoperative imaging to delineate lesion extent and vascular supply including contrast-enhanced computed tomography and other examinations depending on its size and characteristics.
CASE PRESENTATION
The patient was a 34-year-old female with a mass measuring approximately 67 × 42 × 65 mm in the left posterior mediastinum. Intraoperatively, the mass demonstrated rich vascularity. Two veins originating from the abdominal cavity entered the lower pole, one converged from the superior pole, draining into the brachiocephalic vein. Additionally, two arteries arose directly from the descending aorta, while several veins drained into the intercostal veins. In response to unexpected intraoperative vascular findings, vascular clips and silk threads were used to ligate them. Subsequently, the tumor was successfully dissected, with approximately 600 ml of blood loss recorded during the 4-hour surgery. The patient exhibited a satisfactory postoperative recovery, and follow-up spanning over six months revealed no indications of recurrence or metastasis.
CONCLUSIONS
We firstly present a case of successful resection of a pSFT in a 34-year-old woman with a distinct feeding vessel arising from the descending aorta and describe the related surgical procedures. This case highlights preoperative evaluation of mass vascularity based on contrast-enhanced computed tomography. When blood supply is challenging to clarify, angiography can offer additional details, especially for giant pSFTs. Despite this, thorough intraoperative exploration remains essential to detect unexpected vessels. Appropriate interventions should be customized based on the vascular origins and the surrounding anatomical structures.

BACKGROUND
Hemorrhage is the most common major complication after liver biopsy. Hemothorax is one type of bleeding and is very rare and dangerous. Several cases of hemothorax subsequent to liver biopsy have been documented, primarily attributed to injury of the intercostal artery or inferior phrenic artery and a few resulting from lung tissue damage; however, no previous case report of hemothorax caused by injury of musculophrenic artery after liver biopsy has been reported.
CASE PRESENTATION
A 45-year-old native Chinese woman diagnosed with primary biliary cirrhosis due to long-term redness in urination and abnormal blood test indicators was admitted to our hospital for an ultrasound-guided liver biopsy to clarify pathological characteristics and disease staging. A total of 2 hours after surgery, the patient complained of discomfort in the right chest and abdomen. Ultrasound revealed an effusion in the right thorax and hemothorax was strongly suspected. The patient was immediately referred to the interventional department for digital subtraction angiography. Super-selective angiography of the right internal thoracic artery was performed which revealed significant contrast medium extravasation from the right musculophrenic artery, the terminal branch of the internal thoracic artery. Embolization was performed successfully. The vital signs of the patient were stabilized after the transarterial embolization and supportive treatment.
CONCLUSION
This case draws attention to the musculophrenic artery as a potential source of hemorrhage after percutaneous liver biopsy.

Cerebrovascular resistance (CVR) regulates blood flow in the brain, but little is known about the vascular resistances of the individual cerebral territories. We present a method to calculate these resistances and investigate how CVR varies in the hemodynamically disturbed brain. We included 48 patients with stroke/TIA (29 with symptomatic carotid stenosis). By combining flow rate (4D flow MRI) and structural computed tomography angiography (CTA) data with computational fluid dynamics (CFD) we computed the perfusion pressures out from the circle of Willis, with which CVR of the MCA, ACA, and PCA territories was estimated. 56 controls were included for comparison of total CVR (tCVR). CVR were 33.8 ± 10.5, 59.0 ± 30.6, and 77.8 ± 21.3 mmHg s/ml for the MCA, ACA, and PCA territories. We found no differences in tCVR between patients, 9.3 ± 1.9 mmHg s/ml, and controls, 9.3 ± 2.0 mmHg s/ml (p = 0.88), nor in territorial CVR in the carotid stenosis patients between ipsilateral and contralateral hemispheres. Territorial resistance associated inversely to territorial brain volume (p < 0.001). These resistances may work as reference values when modelling blood flow in the circle of Willis, and the method can be used when there is need for subject-specific analysis.

Celiac trunk and superior mesenteric artery (SMA) are the main blood supply to the liver and pancreas. The data of anatomical variations in these arteries or their branches are very important clinically and surgically. The aim of this study was to describe the different variants in these arteries through the examination of the angiographs of a large series of Egyptian individuals. This research involved 389 selective angiographies to celiac artery, its branches, and the SMA. Anatomy of the target arteries of people who experienced visceral angiograph was reviewed and the data were recorded. From the total available angiograms in this work, 286 patients (73.52%) had the standard anatomy of celiac trunk and superior mesenteric arteries, and 103 patients (26.47%) had a single or multiple vessel variation. The inferior phrenic artery originates from celiac trunk in 2.05% of patients, while quadrifurcation of the celiac trunk was noticed in only 0.51% of patients. Absence of celiac trunk is also found in 0.51% of patients. Left gastric artery showed an abnormal origin from the splenic artery in 0.51% of patients. Quadrifurcation of common hepatic artery was also noticed. Variant anatomy of the left hepatic artery (LHA) was seen in 9.51% of patients, while variations of the right hepatic artery (RHA) were 14.13%. With the different origin of hepatic arteries, the gastroduodenal artery arose either from the LHA (2.82%), RHA (2.31%) or even from the celiac trunk (1.79%).

Persistent trigeminal artery disease is one of the most common types of persistent carotid-vertebrobasilar anastomoses. Usually, it is unilateral, and it can be discovered with a magnetic resonance angiography (MRA), computed tomography angiography (angioCT), or classic angiography exam. It can be associated with non-specific symptoms, such as headaches, or more specific ones, such as III or VI nerve palsy or trigeminal neuralgia, but most of the time it goes undetected, being an incidental finding and not causing any symptoms. On MRA and angioCT, it has the characteristic "tau" sign. We present the case of a young woman who, incidentally, discovered this malformation after undergoing an MRA. She had been experiencing a persistent headache without a known cause, which did not improve despite medication.

Ischemic myocardial injury in a diabetes mellitus (DM) patient can be a trigger or a complication of diabetic ketoacidosis (DKA). This case series examines the phenomenon of elevated troponin levels in patients with DKA in the absence of obstructive coronary artery disease. Two out of three cases showed ST-segment elevation on electrocardiogram (EKG). Despite the absence of obstructive coronary artery disease on coronary angiography, all cases exhibited troponinemia (>79 ng/dl). These elevated troponin levels and EKG changes may pose diagnostic challenges for clinicians. Alternatively, troponinemia could be due to myocardial injury caused by acidotic stress and free fatty acid utilization along with increased myocardial oxygen demand and not obstructive coronary artery pathology in every case. However, a better understanding of the complex interplay between DKA and myocardial injury needs further research.

Peripheral artery disease (PAD) is the buildup of calcium and fatty deposits in the arterial walls (atherosclerosis). This is an important clinical issue, specifically in cases with multilevel lesions. A patient underwent sequential angioplasty treatment for major PAD, which was characterized by multilevel lesions affecting both the infrapopliteal arteries. The proximal vessels and infrapopliteal vessels are mostly observed to be affected by PAD, thus the patient likely has PAD localized to the lower leg. In the femoropopliteal segment, lower extremity artery or aortic atherosclerotic occlusive disease can lead to significant outcomes. Severe claudication and pain during rest in both legs were observed in a patient with a history of hypertension and diabetes mellitus. With an angiography, the superficial femoral, popliteal, and tibial arteries have been shown to have major stenoses and occlusions. A progressive treatment was used because of the complexity of the lesions initiating with endovascular revascularization of the superficial femoral artery. The popliteal and tibial arteries were then repaired with angioplasty and stent placement. After the treatment, the patient's symptoms significantly improved, including elimination of their rest discomfort and claudication. Measurements of the ankle-brachial index (ABI) indicated that the affected limbs' perfusion was refined. Six months later, a follow-up angiography revealed intact vessels with no restenosis. This case report shows the successful outcome of recurrent angioplasty in curing complicated multilevel PAD, giving symptomatic relief and maintaining limb perfusion. This research is required to assess the long-term outcomes and longevity of this kind of treatment in patient populations that are comparable to others.

Bronchial Dieulafoy's disease (BDD), remains poorly understood, with only 88 cases reported globally. Herein, we present the largest case series ( = 7) from a single centre, between 2017 and 2023, retrospectively reviewed, detailing clinical presentations, diagnoses, management and up to 4-year follow-up outcomes. Diagnosis relied on characteristic lesions detected through white light bronchoscopy with or without endobronchial ultrasound (EBUS) or narrow band imaging (NBI), along with computed tomography (CT) scans or bronchial angiography. Identification of aberrant vessels beneath lesions and bronchoscopy details were documented. Treatment modalities and follow-up outcomes until December 2023 were noted. All patients were non-smokers. Review of imaging findings by an experienced radiologist was crucial in suspected cases due to risk of bleeding and often unconclusive results from biopsy. Management of BDD varied, with six patients undergoing bronchial artery embolization (BAE) and one requiring lobectomy; four patients received additional endobronchial therapy, one died due to malignancy, none experienced recurrence of haemoptysis. Identifying patients with large volume haemoptysis disproportionate to parenchymal disease in CT scans is important. A bronchoscopic surveillance is crucial to avoid biopsy; it can be confirmed using EBUS of NBI. While no established guidelines exist, BAE and endobronchial therapy emerge as valuable interventions, with surgical resection reserved for recurrent cases.
