BACKGROUND: It is frequently observed that patients with first-ever acute ischemic stroke (AIS) have a common occurrence of asymptomatic coronary artery disease (CAD). This condition is associated with a poor prognosis. Early detection and recognition of asymptomatic CAD in first-ever AIS patients may optimize the clinical management and ultimately lead to improved outcomes. The aim of this study was to investigate the role of aortic arch plaque (AAP) detected through combined computed tomography angiography (CTA) as an early predictor of asymptomatic CAD in patients with first-ever AIS without prior diagnosis of CAD...

BACKGROUND: Microvascular visualization is crucial in understanding the mechanisms of several pathologies. For instance, visualization of the tumor microenvironment is important in understanding angiogenesis and role in cancer progression. Visualization would provide insights to cancer diagnosis, predicting metastatic growth, and evaluating therapeutic protocols. Similarly, understanding the microvascular network could be beneficial for study of degenerative diseases and tissue repair...

We report the case of a 77-year-old woman presenting with an asymptomatic internal carotid artery (ICA) aneurysm arising at the skull base. The distal right extracranial ICA aneurysm presented as a challenging case due to difficulty in obtaining adequate surgical exposure and preserving the facial nerves present near the ICA aneurysm. Transcervical open repair with a team of vascular and otolaryngology surgeons was completed successfully. In this report, we detail the operative steps needed to complete this exposure and our perioperative management...

Craniopharyngioma (CP) treatment, including surgery and radiotherapy, can have short- and long-term vascular side effects. Hypothalamic damage is related to morbid obesity and may increase the lifelong risk of experiencing vascular events in CP patients. This review summarized the available evidence regarding vascular complications in adamantinomatous or papillary CP patients, whatever their age at diagnosis. Three databases (Medline, CINAHL, Web of Science) were searched (06/2023) to retrieve eligible articles...

Biotubes are autologous tubular tissues developed within a patient's body through in-body tissue architecture, and they demonstrate high potential for early clinical application as a vascular replacement. In this pilot study, we used large animals to perform implantation experiments in preparation for preclinical testing of Biotube. The biological response after Biotube implantation was histologically evaluated. The designed Biotubes (length: 50 cm, internal diameter: 4 mm, and wall thickness: 0.85 mm) were obtained by embedding molds on the backs of six goats for a predetermined period (1-5 months)...

Clazosentan, a potent selective endothelin receptor subtype A antagonist, has been demonstrated to be effective in preventing cerebral vasospasms after subarachnoid hemorrhage. We report the successful management of respiratory failure due to pulmonary edema associated with clazosentan, with a hemodynamic monitoring system. A 49-year-old Japanese man underwent emergency clipping for a right internal carotid-posterior communicating artery aneurysm. The surgery and general anesthesia for the rupture proceeded with no complications...

PURPOSE: The endoscopic trans-eustachian approach (ETETA) is a less invasive approach to the infratemporal fossa (ITF), providing superior exposure compared to traditional transcranial approaches. The anatomy of the pharyngotympanic (eustachian) tube and adjacent neurovascular structures is complex and requires in-depth knowledge to safely perform this approach. We present a cadaveric and radiological assessment of critical anatomic considerations for ETETA. METHODS: Six adult cadaveric heads were dissected alongside examination of 50 paranasal sinus CT scans...

Objective: To assess the impact of intravascular laser irradiation of blood (ILIB) on the primitive carotid artery (PCA) hemodynamic variables, specifically blood pressure (BP) and heart rate (HR), in mastectomized patients undergoing hormone blocker treatments. Materials and methods: This study is a controlled, experimental, and randomized clinical trial. Patients were allocated into two groups: the experimental group (G1)-patients who received ILIB therapy using a 660 nm laser targeted at the PCA, and the control group (G2)-patients who did not receive ILIB therapy...

BACKGROUND: Stroke is a much-feared complication of cardiac surgery, but existing literature on preventive strategies is fragmented. Hence, a systematic review and meta-analysis of stroke prevention strategies for cardiac surgery was conducted. METHODS: An electronic literature search was conducted to retrieve randomized controlled trials (RCTs) investigating perioperative interventions for cardiac surgery, with stroke as an outcome. Random-effects meta-analyses were conducted to generate risk ratios (RRs), 95% confidence intervals (95% CI), and forest plots...

Sreetama Mukherjee, Arvind Bhake
A carotid body tumor is a rare form of neoplasm that arises near the carotid artery bifurcation and it has an incidence rate of less than 0.3 per 100,000 population. The low incidence rate of such tumors is due to their origination from the paraganglion cells which is relatively uncommon as compared to other forms of tumor. Here we present an incidental and unusual cytodiagnosis of carotid body tumors. A 45-year-old male presented to the surgery outpatient department with swelling in the left-sided anterior region of the neck...

PURPOSE: Endoscopic pituitary surgery entails navigating through the nasal cavity and sphenoid sinus to access the sella using an endoscope. This procedure is intricate due to the proximity of crucial anatomical structures (e.g. carotid arteries and optic nerves) to pituitary tumours, and any unintended damage can lead to severe complications including blindness and death. Intraoperative guidance during this surgery could support improved localization of the critical structures leading to reducing the risk of complications...

OBJECTIVE: The management of lesions involving the cavernous sinus remains a formidable challenge. To optimize care for patients with tumors extending into this skull base region a detailed understanding of the surrounding osteology as well as neural and vascular relationships is requisite. This thesis examines the gross anatomy of the region and highlights important surgical implications drawn from these as well as previously published studies. METHODS: A review of the historical scientific, anatomic, clinical, and surgical literature extending to the present (1992) relating to the cavernous sinus has been performed and discussed...

The carotid body, situated at the common carotid artery bifurcation, comprises specialized glomus cells responsible for sensing blood oxygen, carbon dioxide, pH, and temperature changes, crucial for regulating breathing and maintaining oxygen homeostasis. Carotid body tumors (CBTs), arising from these cells, are rare, representing only 0.5% of head and neck tumors, often presenting as benign, slow-growing, vascularized masses. In February 2023, this bibliometric analysis was conducted, which involved screening 1733 articles from the Web of Science database...

A patient in his late 30s presented with issues of retrosternal chest pain and palpitations. He had sustained a splinter injury to the left hemithorax a year ago for which he had been managed with a tube thoracostomy. During subsequent evaluations, he was found to have atrial fibrillations and a CT angiography revealed an arch of the aorta pseudoaneurysm with a fistulous communication with the innominate vein, which being a rare condition has no established treatment protocols. Endovascular salvage of the condition required an aortic Ishimaru zone 2 deployment of the thoracic endovascular aortic repair stent graft to provide an adequate landing zone...
