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.

Rotational atherectomy is an effective procedure for heavily calcified lesions and those that cannot be crossed using conventional percutaneous coronary intervention (PCI) devices. Here, we report a rare case of intracoronary burr entrapment in the coronary artery due to burr disconnection from the driveshaft. A 67-year-old man undergoing hemodialysis for nephrosclerosis presented with exertional chest discomfort. Coronary angiography revealed stenotic lesions in the right coronary artery, and PCI was performed using a Rotawire Floppy. During the procedure, the disconnected burr was successfully removed without surgery using the child-in-mother technique with a guide extension catheter. Notably, the patient remained hemodynamically stable throughout the procedure and his recovery was uncomplicated. He was discharged on the second postprocedural day. At the 6-month follow-up, the patient remained asymptomatic with no evidence of myocardial ischemia. This report informs clinicians of the possibility of burr disconnection and the non-surgical intervention used for its removal.

BACKGROUND
The aim of this work was to create and evaluate a preoperative non-contrast-enhanced (CE) magnetic resonance imaging (MRI)/angiography (MRA) protocol to assess renal function and visualize renal arteries and any abnormalities in potential living kidney donors.
METHODS
In total, 28 subjects were examined using scintigraphy to determine renal function. In addition, 3D-pseudocontinuous arterial spin labeling (pCASL), a 2D-non-CE electrocardiogram-triggered radial quiescent interval slice-selective (QISS-MRA), and 4D-CE time-resolved angiography with interleaved stochastic trajectories (CE-MRA) were performed to assess renal perfusion, visualize renal arteries and detect any abnormalities. Two glomerular filtration rates [described by Gates (GFR) and according to the Chronic Kidney Disease Epidemiology Collaboration formula (GFR)]. The renal volumes were determined using both MRA techniques.
RESULTS
The mean value of regional renal blood flow (rRBF) on the right side was significantly higher than that on the left. The agreements between QISS-MRA and CE-MRA concerning the assessment of absence or presence of an aberrant artery and renal arterial stenosis were perfect. The mean renal volumes measured in the right kidney with QISS-MRA were lower than the corresponding values of CE-MRA. In contrast, the mean renal volumes measured in the left kidney with both MRA techniques were similar. The correlation between the GFR and rRBF was compared in the same manner as that between GFR and rRBF.
CONCLUSION
The combination of pCASL and QISS-MRA constitute a reliable preoperative protocol with a total measurement time of <10 min without the potential side effects of gadolinium-based contrast agents or radiation exposure.

Observational Study
Superficial ocular vascular changes after orbital decompression in patients with thyroid ophthalmopathy measured by anterior segment OCT angiography; an observational study.
Thyroid eye disease (TED) is a common ophthalmologic manifestation of thyroid dysfunction. Despite various imaging techniques available, there hasn't been a widely adopted method for assessing the anterior segment vasculature in TED patients. Our study aimed to evaluate alterations in ocular surface circulation following orbital decompression surgery in TED patients and investigate factors influencing these changes. Using anterior segment optical coherence tomography-angiography (AS-OCTA), we measured ocular surface vascularity features, including vessel density (VD), vessel diameter index (VDI), and vessel length density (VLD), both before and after decompression surgery, alongside standard ophthalmic examinations. Our AS-OCTA analysis revealed a significant decrease in most of the temporal vasculature measurements six weeks post-surgery (p < 0.05). However, differences in the nasal region were not statistically significant. These findings indicate notable changes in ocular surface circulation following orbital decompression in TED patients, which may have implications for intraocular pressure (IOP) control and ocular surface symptoms management. AS-OCTA holds promise as a tool for evaluating the effectiveness of decompression surgery and assessing the need for further interventions.

JAMA Network Open Jun 2024Data are limited regarding the effects of intravascular imaging guidance during complex percutaneous coronary intervention (PCI) in patients with diabetes. (Randomized Controlled Trial)
Randomized Controlled Trial
Intravascular Imaging and Angiography Guidance in Complex Percutaneous Coronary Intervention Among Patients With Diabetes: A Secondary Analysis of a Randomized Clinical Trial.
IMPORTANCE
Data are limited regarding the effects of intravascular imaging guidance during complex percutaneous coronary intervention (PCI) in patients with diabetes.
OBJECTIVE
To compare the clinical outcomes of intravascular imaging-guided vs angiography-guided complex PCI in patients with or without diabetes.
DESIGN, SETTING, AND PARTICIPANTS
This prespecified secondary analysis of a subgroup of patients in RENOVATE-COMPLEX-PCI (Randomized Controlled Trial of Intravascular Imaging Guidance Versus Angiography-Guidance on Clinical Outcomes After Complex Percutaneous Coronary Intervention), an investigator-initiated, open-label multicenter trial, analyzed enrolled patients who underwent complex PCI at 20 sites in Korea from May 2018 through May 2021. Eligible patients were randomly assigned in a 2:1 ratio to undergo either the intravascular imaging-guided PCI or angiography-guided PCI. Data analyses were performed from June 2023 to April 2024.
INTERVENTIONS
Percutaneous coronary intervention was performed either under the guidance of intravascular imaging or angiography alone.
MAIN OUTCOMES AND MEASURES
The primary end point was target vessel failure (TVF), defined as a composite of cardiac death, target vessel-related myocardial infarction, or target vessel revascularization.
RESULTS
Among the 1639 patients included in the analysis (mean [SD] age, 65.6 [10.2] years; 1300 males [79.3%]), 617 (37.6%) had diabetes. The incidence of TVF was significantly higher in patients with diabetes than patients without diabetes (hazard ratio [HR], 1.86; 95% CI, 1.33-2.60; P < .001). Among patients without diabetes, the intravascular imaging-guided PCI group had a significantly lower incidence of TVF compared with the angiography-guided PCI group (4.7% vs 12.2%; HR, 0.41 [95% CI, 0.25-0.67]; P < .001). Conversely, in patients with diabetes, the risk of TVF was not significantly different between the 2 groups (12.9% vs 12.3%; HR, 0.97 [95% CI, 0.60-1.57]; P = .90). There was a significant interaction between the use of intravascular imaging and diabetes for the risk of TVF (P for interaction = .02). Among patients with diabetes, only those with good glycemic control (hemoglobin A1c level ≤7.5%) and who achieved stent optimization by intravascular imaging showed a lower risk of future ischemic events (HR, 0.31; 95% CI, 0.12-0.82; P = .02).
CONCLUSIONS AND RELEVANCE
In this secondary analysis of a subgroup of patients in the RENOVATE-COMPLEX-PCI trial, intravascular imaging guidance reduced the risk of TVF compared with angiography guidance in patients without diabetes (but not in patients with diabetes) during complex PCI. In patients with diabetes undergoing complex PCI, attention should be paid to stent optimization using intravascular imaging and glycemic control to improve outcomes.

Inferior phrenic artery (IPA) aneurysms are the rarest type of visceral aneurysms. It usually occurs secondary to trauma, surgery, or as a complication of pancreatitis. In addition, it can be a manifestation of underlying systemic pathology such as vasculitis, collagen vascular disorders, sepsis, or segmental arterial mediolysis. It can be associated with hypertension in 43% of cases. The presentation of IPA aneurysm is nonspecific with abdominal pain, melena, hematochezia, and anemia. The ruptured and actively bleeding aneurysm can lead to hemorrhagic shock, and immediate management is required with angiography and endovascular embolization with coil or gel foam or stent etc. Inaccessible locations are reached with surgical intervention, but it is associated with high morbidity and mortality. We here report a rare case of spontaneously ruptured IPA pseudoaneurysm extending from the posterior mediastinum to the subdiaphragmatic area and managed with coil and gel foam embolization.

Trauma is a significant cause of morbidity and mortality worldwide among children. Nonoperative management is the standard of care in hemodynamically stable children with blunt abdominal solid organ injury. Embolization is a potential pathway, which has shown increasing evidence for benefit in adult trauma patients. However, the data in children is limited. A retrospective analysis of hospital data of all children (<18 years of age), presenting to a tertiary-care trauma center in India, with history of blunt trauma from January 2021 to June 2023, was performed. Preprocedural imaging, angiographic and embolization details, number of blood transfusions, and length of hospital stay were assessed. Two hundred and sixteen children (average age: 11.65 years) presented with a history of abdominal trauma during the study period. Eighty four children were FAST positive, out of whom, 67 patients had abdominal solid organ injury on computed tomography. Liver was the most commonly injured solid organ ( = 45), followed by the spleen and kidney. Ten children had solid abdominal organ arterial injuries for which eight children underwent embolization. The average length of hospital stay in embolization group ( = 8) was 4 days, as compared to 11 days in children undergoing operative management ( = 2). At 6 months follow-up, all children were asymptomatic. Superselective embolization is a safe and feasible procedure in appropriately selected children with abdominal injury.

Contrast-enhanced ultrasound (CEUS) can reliably identify vulnerable plaques. As atherosclerosis is a systemic disease, we evaluated whether contrast enhancement of carotid plaque (CECP) can predict severe coronary artery disease (CAD) by comparing CECP in patients who have had acute coronary syndromes (ACS) recently with asymptomatic individuals. This case-control study was done at a tertiary care center during 2022. Fourteen participants were recruited in each group, after screening in-patients for carotid plaques and inclusion and exclusion criteria. Those who had history of ACS were enrolled as cases, while those who did not were enrolled as controls. All these patients underwent grayscale, Doppler, and CEUS examination for characterization of the carotid plaque. For cases, findings on CEUS were also compared with the severity of CAD on catheter coronary angiography. Diagnostic parameters including sensitivity, specificity, and diagnostic accuracy were calculated and proportions were compared by using Fisher's exact test. Eight out of 28 patients showed CECP. CECP and CAD were positively associated with -Value of 0.033. Eighty-three percent patients with triple vessel disease and 50% patients with double vessel disease on coronary angiography showed CECP. Sensitivity and specificity of CECP for prediction of CAD were 50 and 92.9%, respectively. CECP on CEUS can predict CAD and is a more reliable indicator of severe CAD than plaque characteristics on grayscale and Doppler imaging; making it useful for screening of patients at risk of having CAD.

BACKGROUND
Vasospastic angina (VSA) and spontaneous coronary artery dissection (SCAD) are challenging causes of non-atherosclerotic acute coronary syndromes (ACS). Here, we report a unique ACS case with coexisting VSA and SCAD, highlighting specific strategies in diagnosis and management of these poorly studied conditions.
CASE SUMMARY
A woman in her mid-60s with a history of suspected microvascular angina and no atherosclerosis in a previously performed coronary computed tomography angiography presented with worsening chest pain. Invasive coronary angiography revealed a focal SCAD with a resulting high-degree stenosis of the right coronary artery. Shortly after successful percutaneous coronary intervention with stent implantation and stopping her previous vasodilator therapy with nitroglycerine and molsidomine, the patient developed recurrent anterior non-ST-segment elevation myocardial infarction. Surprisingly, repeat coronary angiography revealed severe multifocal coronary artery spasms that were successfully treated with intracoronary nitroglycerine. Vasospastic angina was subsequently managed with diltiazem, molsidomine, and nitrates.
DISCUSSION
Our report underscores the challenges in diagnosing and managing SCAD and VSA in ACS. The possible interplay between SCAD and VSA highlights the need for careful vasodilator therapy management, as seen in our patient, where therapy discontinuation led to severe multifocal VSA. This emphasizes the need for a comprehensive approach for optimal outcomes in complex ACS cases.
