A Rare Case Report of a Vertebral Artery Variant Arising From the Aorta With Its Clinical Significance: An Uncommon Anatomy Unveiled.

The vertebrobasilar (VB) system, comprising two vertebral arteries and one basilar artery, is responsible for providing vital vascular supply to the central nervous system structures. Disruption in this network can lead to fatal neurologic outcomes, and variations in the origin of vessels may contribute to unexplained symptoms of clinical relevance. Therefore, an extensive understanding of the VB system's anatomy and its variations is crucial for diagnosing neurological disorders. Here, we report a case of a vertebral artery variant arising from the aortic arch proximal to the left subclavian artery in the cadaver of a 50-year-old male, discovered incidentally during a teaching dissection session. We also discuss the clinical pathophysiology and the relevance of the neurological symptoms in relation to the anomaly.

A Unique Case of Facial Hypervascularity Responding to Pulsed-Dye Laser.

Facial hypervascularity is a condition that manifests as erythema and edema caused by aberrant blood vessels. Often, the cause of these abnormal blood vessels can be attributed to previous trauma or vascular conditions such as rosacea, although sometimes the cause is unknown. Pulsed dye laser (PDL) can be an effective treatment even when the cause is unknown. We present a case of a 24-year-old male presenting with intermittent swelling, redness, and throbbing sensations of the nose and cheeks for the past five years. Physical examination was notable for prominent erythema and swelling of the nasal skin and mild erythema on the cheeks. He underwent treatment with PDL and achieved complete resolution of his symptoms. This case illustrates the effectiveness of PDL in the treatment of facial hypervascularity.

Aberrant Vessel with Potential Catastrophic Vascular Complications in a Patient with Chiari Malformation.

Craniovertebral junction anomalies are known to be associated with many bony, soft tissue, and vascular anomalies. We encountered a case of Chiari malformation type 1 with C2-D2 syrinx, in which computed tomography angiography showed an aberrant vessel (probably vein) coursing through the soft tissue along the posterior aspect of C1-C7 vertebral bodies along the right-sided joints, superiorly coursing posterior to C1-C2 joint and curving anteriorly over C1 to enter into the foramen magnum. Had this abnormality not been detected, catastrophic vascular consequences could have occurred.

Incomplete Renal Duplex System with Lower Moiety Hydroureteronephrosis Due to Aberrant Blood Vessel.

INTRODUCTION: Duplex collecting system is a common congenital urinary system anomaly and is usually asymptomatic. Vascular variations associated with a duplex system are common but haven't been reported as obstructive. CASE REPORT: 14-month-old female had a right sided incomplete ureteral duplication complicated by lower pole hydroureteronephrosis due to distal ureteral obstruction by an aberrant vessel crossing the bifid ureters at ureteric junction of these bifid ureters. Prenatal imaging detected right hydronephrosis. Magnetic resonance suggested a diagnosis of duplicated ureters. At surgery, an aberrant artery compressed the lower moiety ureter at the bifid ureteric junction. The stenotic section was resected and ureter segments were anastomosed. The occluding small artery was not resected to preserve vascularization. DISCUSSION/CONCLUSION: An anatomical vascular variation can cause proximal ureteral dilatation and segmental hydronephrosis in a bifid system.

Dilated cardiomyopathy as a rare presentation of the pulmonary sequestration: A case report with aberrant vessel from aorta to left lower pulmonary lobe.

Late onset non-ischemic cardiomyopathy is a rare manifestation of the presence of aberrant vessel from descending thoracic aorta to left lower lobe of lung. This congenital anomaly is associated with pulmonary sequestration. Our case was a 23-year-old male who was under observation since the age of 19 years for evaluation of shortness of breath, functional class II. He had history of professional athletic training and he denied consumption of any compound. Ejection fraction had deteriorated during three years from 45-50% to 40% and left ventricular size increased from normal size to mild enlargement. Cardiac computed tomography showed presence of aberrant artery from descending aorta to left lower pulmonary lobe with pulmonary sequestration. His cardiac function improved after successful coil embolization of aberrant vessel. In conclusion, pulmonary sequestration and aberrant pulmonary supply from aorta should be considered as a rare cause of dilated cardiomyopathy which can be reversible by proper intervention. .

Computed tomography angiography with 3D reconstruction in diagnosis of hydronephrosis cause by aberrant renal vessel: A case report and mini review.

BACKGROUND: Congenital hydronephrosis is often caused by aberrant renal vessel and it is difficult to be diagnosed and treated at the early stage due to lack of the significant symptoms. Although current medical diagnosis tools are widely used, the aberrant renal vessel cannot be displayed very well in the images. OBJECTIVE: To investigate whether applying computed tomography (CT) angiography with 3D reconstruction can improve efficacy in diagnose of this congenital hydronephrosis. MATERIALS AND METHODS: A male patient of 18 years old was diagnosed as hydronephrosis of left kidney. A CT angiography with 3D reconstruction was evaluated in diagnosis of the prenatal hydronephrosis compared to ultrasound (US) and intravenous urogram (IVU). RESULTS: US and IVU images were able to display the dilation of left pelvic and the dilated calyces, and the thinner of renal parenchyma on the left kidney (Grade II-IV), but failed to detect the causing of hydro-nephrosis. CT angiography with 3D reconstruction provided accurate images of the dilated renal pelvic, upper segment of the ureter, and an aberrant vessel bundle overcrossing at the left renal pelvic-ureter junction as well. The aberrant vessel could be revealed during surgery. CONCLUSIONS: A CT angiography with 3D reconstruction provides a more accurate diagnostic approach for the congenital hydronephrosis caused by aberrant renal vessel. Thus, it can offer surgeons very important information in the pre-surgery planning.

Embolización transcatéter con dispositivo, una promisoria opción en el tratamiento del secuestro pulmonar: casos clínicos / Transcatheter embolization device as a promising option in the treatment of pulmonary sequestration: case reports

Introducción: El secuestro pulmonar (SP) ha sido tratado por muchos años con cirugía convencional efectuando remoción del tejido pulmonar ectópico y ligadura de los vasos sanguíneos aberrantes que nacen desde la aorta. Existe evidencia establecida, especialmente en literatura de habla inglesa que apoya el uso de la embolización arterial transcatéter mediante dispositivo para ocluir el vaso anómalo, como una opción de tratamiento seguro y definitivo para el SP intralobar. Objetivo: Mostrar nuestra experiencia pionera de la técnica de tratamiento del SP por medio de embolización transcatéter. Caso clínico: Presentamos los casos clínicos de dos adolescentes, de 13 y 14 años y de un recién nacido de 26 días de vida, portadores de SP intralobar, cuyos diagnósticos se realizaron a través de Tomografía Axial Computarizada (TAC) con contraste, tratados mediante embolización arterial transcatéter, con buen resultado y sin complicaciones en el seguimiento precoz y tardío. Conclusión: Con este tratamiento se logra en los pacientes afectados de SP resultados definitivos, menos invasivos y sin complicaciones al seguimento.

Introduction: Pulmonary sequestration (PS) has been treated for many years with conventional surgical removal of the ectopic lung tissue and ligation of aberrant vessels that arise from the aorta. There is evidence, especially in English-language literature that supports the use of transcatheter arterial embolization through a device for occlusion of the anomalous vessel, as a safe option and definitive treatment for intralobar PS. Objective: To show our experience pioneering the technique of PS treatment through transcatheter embolization. Case report: The case reports of two teenagers aged 13 and 14 and a 26-day-old newborn that developed intralobar PS are described. The diagnosis was made through computerized axial tomography (CT scan) and successfully and without complication, during early and long term follow-up, treated by arterial embolization transcatheter. Conclusion: The use of transcatheter arterial embolization is a less invasive and definitive treatment for patients with PS.

Aberrant renal vessel causing hydronephrosis in crossed-fused ipsilateral ectopic kidney: a rare case report.

A crossed-fused ectopic kidney is a rare congenital anomaly, and uncommonly we see an aberrant vessel as a cause of hydronephrosis in a kidney. We report a case of 4-year-old boy with crossed-fused right renal ectopia with hydronephrosis in the both kidneys. The aberrant renal vessel was found pressing the left pelvi-ureteric junction causing hydronephrosis. Dismembered pyeloplasty of the left kidney was performed anterior to the aberrant vessel. The patient is doing well in the follow-up visits and his renal function is stabilized. Aberrant blood supply may be a cause of hydronephrosis in the crossed-fused ectopic ipsilateral kidney. Keeping this entity in differential diagnosis will help in successful management of the crossed-fused ectopic kidney.

Ureteropelvic Junction Obstruction Caused by Aberrant Vessel of Kidney:Diagnostic Value of Contrast-Enhanced CT Scan with Split Bolus / 实用放射学杂志

Objective To study the diagnostic value of contrast-enhanced CT scan with split bolus for the ureleropelvic junction obstruction(UPJO) caused by aberrant vessel of kidney.Methods 52 patients with UPJO underwent contrast-enhanced CT scan with split bolus.The aberrant vessels and its origin as well as the relationship between aberrant vessels and UPJO were observed comparatively with the results of surgery.Results In 52 cases,CT showed UPJO caused by aberrant vessl of kidney in 14 cases,including accessory renal arteries in 10,ovarian artery originated from left renal artery in one,right accessory renal artery in one and gonad veins in 2.CT findings were corresponded to operations in all these 14 cases.The sensitivity and specificity of CT in evaluating UPJO were 100% respectively.Conclusion The UPJO caused by aberrant vessel of kidney can be diagnosed accurately by contrast-enhanced CT scan with split bolus,which can be offered for surgical treatment for UPJO.The patient's CT dose can be decreased with split bolus.

Diagnostic Value of Color Doppler Ultrasonography of UPJ Obstruction / 대한비뇨기과학회지

The cause of ureteropelvic junction obstruction(UPJ) is almost due to intrinsic factor. But a small percentage of UPJ obstruction have extrinsic obstruction as a result of a crossing renal aberrant vessel. The diagnosis of UPJ obstruction by aberrant vessel is usually made at surgery because the urographic findings are nonspecific and difficult to find cause. For the purpose of detecting aberrant vessel as a cause of UPJ obstruction, authors examined 20 patients with color Doppler ultrasonographic equipment, then cause of obstruction was confirmed at the time of surgery, from July 1991 to February 1994. In seven of twenty patients aberrant vessel was detected by color Doppler ultrasonographic equipment. Among the seven patients, only three cases were caused directly by aberrant vessel, color Doppler examination disclosed a vessel or vessels at the tapering distal end of UPJ. In other two patients, aberrant vessel was detected but it was not direct cause of UPJ obstruction. Even in two of seven patients, aberrant vessel was not detected at the time of surgery. However in one of thirteen patients with no color Doppler signal at the UPJ, aberrant vessel was confirmed in surgical field. Sensitivity was 75 % and specificity was 75 % as detecting aberrant vessel by color Doppler ultrasonographic equipment. We believe that color Doppler examination is a useful method in demonstration of aberrant vessel as a cause of UPJ obstruction, although accuracy was low.
