A Case of Atraumatic Pseudoaneurysm of Superficial Temporal Artery

Pseudoaneurysm of the superficial temporal artery (STA) is a rare vascular lesion that typically presents after traumatic head injury. Most of them occur mainly in the anterior branch of the STA, and their occurrence in the preauricular region without any history of trauma is very uncommon. In this article, we describe a 78-year-old female patient presenting a painless preauricular, pulsatile mass without any history of facial trauma. The mass was completely removed following ligation and division of STA both proximally and distally. In most case reports, the diagnosis was performed with thoughtful history taking and physical examination. Diagnostic imaging is especially useful in cases of STA aneurysm without any history of trauma. Herein, we present a rare case of preauricular pseudoaneurysm of STA with a literature review.

True superficial temporal artery aneurysm: A case after extracranial-intracranial bypass surgery and a systematic review.

Nontraumatic true superficial temporal artery aneurysm (STAA) is rare, and its characteristics and pathogenesis are unclear. We report a case of STAA and performed a systematic review of PubMed, Scopus, and Web of Science using the keyword "superficial temporal artery aneurysm" to include studies on STAA reported through July 2022. We excluded studies on STAA associated with trauma, arterial dissection, infection, or vasculitis. A 63-year-old woman who underwent left superficial temporal artery (STA)-middle cerebral artery bypass surgery 8 years previously was diagnosed with an aneurysm located at the left STA. The blood flow volume estimated by ultrasonography was higher in the left STA than in the contralateral counterpart (114 mL/min vs. 32 mL/min). She underwent clipping surgery to prevent aneurysmal rupture without sequela. The lesion was diagnosed as a true aneurysm by histology. The systematic review identified 63 cases (including the present case) of nontraumatic true STAA. The median age of the patients was 57 (interquartile range [IQR]: 41-70) years. Most (90.5%) cases were detected as a palpable mass. Aneurysmal rupture occurred in only 1 (1.6%) case, despite the large size of aneurysms (median size: 13 [IQR: 8-20] mm) and the high frequency (33.3%) of aneurysmal growth during observation. Most (93.7%) patients underwent surgical resection of STAA without sequela. Our findings suggest that the pathogenesis of true STAA is promoted by hemodynamic stress. The systematic review clarified patients' and aneurysmal characteristics and treatment outcomes, providing further insight into the pathogenesis of nontraumatic true STAA.

Superficial Temporal Artery Aneurysm

The superficial temporal artery aneurysm is a rare pathology. We report the case of a 7-year-old child who consulted for a beating mass on the left forehead. The doppler ultrasound and The CT angiography confirmed the diagnosis of a superficial temporal artery aneurysm. The treatment was surgical and the postoperative course was simple.

TRAUMATIC TRUE ANEURYSM OF SUPERFICIAL TEMPORAL ARTERY: A RARE CASE REPORT

True Superficial temporal artery aneurysm is commonly painful or painless and pulsating mass. It is rarely results from blunt traumatic injury to the side of head. Only small number of these cases has been reported in the previous literature. We describe diagnosis and management of a 34 year old male who had history of physical assault hit by bottle (glass), resulted in developing a true large aneurysm of left superficial temporal artery (STA). Simple selective ligation and excision of STA aneurysm was performed. Patient has been discharged without any post operative complication.

Initial Experience Using the Transradial Approach for Endovascular Treatment of Vascular Pathologies: Safety and Feasibility.

Background Endovascular treatment of vascular pathologies through the transradial approach has been increasingly used and has demonstrated a low rate of complications. Objective To report our initial experience in the endovascular treatment of cerebrovascular diseases with the transradial approach and to determine its safety and feasibility. Methods Consecutive patients who underwent the transradial approach for endovascular treatment of aneurysms and vascular malformations were reviewed at a single institution. Technical success, fluoroscopy time, and access-related complications were analyzed. Results Eight patients underwent endovascular treatment with the transradial approach. One arteriovenous fistula, one superficial temporal artery aneurysm, three arteriovenous malformations, and four aneurysms were treated successfully. The radial artery was successfully approached and a 6-F sheath was used in all the cases. Navigation of guiding catheters (5 and 6 F) was done without complications. The most commonly approached artery was the right internal carotid artery, followed by the right vertebral artery. Postoperative vasospasm was identified in three patients. Mean fluoroscopy time was 34.7 minutes. Conversion to transfemoral approach was not required. No postoperative complications were reported. Conclusions In our initial experience, the transradial approach is a safe and feasible alternative for the endovascular treatment of cerebrovascular pathologies.

Circular RNA circDUS2 Is a Potential Biomarker for Intracranial Aneurysm.

Background: CircRNAs have been found to play a crucial role in the pathological process of various kinds of diseases. However, the role of circRNAs in the formation and rupture of intracranial aneurysm is still unknown.Methods: Differentially expressed circRNAs profiles between superficial temporal arteries (n = 5) and intracranial aneurysms (n = 5) were analyzed using the Arraystar human circRNAs microarray. Quantitative real-time PCR was utilized to validate the differential expression of circDUS2. Fluorescence in situ hybridization (FISH) was meant for the location of circDUS2 in human brain vascular smooth muscle cell (HBVSMC). Structural analysis was used to speculate on the function of circDUS2.Results: Five hundred forty-three upregulated and 397 downregulated significantly in intracranial aneurysm as compared to superficial temporal arteries. Quantitative real-time PCR verified the elevated expression of the upregulated circDUS2. The FISH test revealed that circDUS2 is located in the cytoplasm of brain vascular smooth muscle cells.Conclusion: This study showed differential expression data of circRNAs between superficial temporal artery and intracranial aneurysm and revealed that circDUS2 is a potential molecular marker for intracranial aneurysm.

Superficial Temporal Artery True Fusiform Aneurysm With Several Lateral Feeding Vessels

A 49-year-old man flight attendant with a past medical history of Roux-en-Y bypass and massive weight loss 18 months prior was referred for surgical management of a superficial temporal artery aneurysm. Imaging confirmed the diagnosis. Intraoperatively a 1 cm fusiform aneurysm was identified with numerous feeding side branch vessels. The aneurysm was suture ligated and excised in toto with pathologic analysis showing involvement of all vessel layers. This case highlights a rare true aneurysm of the superficial temporal artery and aberrant anatomy of multiple side branches feeding the aneurysm and complicating dissection and excision.

Posttraumatic true aneurysm of the superficial temporal artery

Most superficial temporal artery (STA) aneurysms are pseudoaneurysms that occur following a trivial trauma to the temporal region. True aneurysms of the STA are very rare. They occur usually due to congenital defects in vessel wall or atherosclerotic degeneration. We report a case of true aneurysm of the STA following trauma which is exceedingly rare. A 23-year-old male presented with painless swelling in front of the right ear for 4 months with a history of trauma to the right temporal region. Examination revealed a painless pulsatile mass of 4 cm × 3 cm size, and the diagnosis was supported by Doppler ultrasound and magnetic resonance imaging. Surgical excision was done. Histological examination showed all the three layers of the arterial wall to be intact, confirming a diagnosis of true aneurysm of the STA.

Pulsatile Temporal Swelling—Successful Removal of a True Superficial Temporal Artery Aneurysm

True superficial temporal artery aneurysms are rare, while pseudo-aneurysms are more common. We report the case of a 43-year-old gentleman who had a pulsatile swelling in the right pre-auricular region with no history of trauma. He underwent an uneventful and curative surgical excision of the aneurysm.

Ultrasound Diagnosis of a Temporal Artery Aneurysm

Superficial temporal artery aneurysms (STAA) are rare, almost always post traumatic, and their diagnosis can be challenging. When a middle aged man presented with a gradually enlarging non-pulsatile left fronto-temporal artery mass we were able to make a diagnosis of STAA using ultrasonography as well as confirm its resolution later following spontaneous thrombosis of the aneurysm.

Case Report: SPONTANEOUS (TRUE) ANEURYSM OF THE SUPERFICIAL TEMPORAL ARTERY

Spontaneous aneurysms of the superficial temporal artery (STA) are rare. Although STA aneurysms have a relatively benign course, when compared with aneurysms of larger caliber arteries, they may occasionally lead to severe hemorrhage and be associated with a multitude of bothersome symptoms. The objective of this study was to report a case of 72-year old male presented with spontaneous STA aneurysm. A 72 years old male presented with a lump on his right temporal side without any previous history of trauma and there was history of long standing hypertension. The lump had first been noticed 2 years before and it had been gradually increasing in size especially within last 6 months. On physical examination there was a pulsatile mass around 2 cm in diameter just above right ear. There was no thrill and bruit. CT angiography showed findings compatible with a STA aneurysm. The patient underwent proximal and distal ligation of the superficial temporal artery and excision of the aneurysm. Histopathological examination confirmed a true aneurysm of STA. The post operative period was uneventful. In conclusion, spontaneous STA aneurysm was best managed by surgical procedure. It consists of ligation and excision. It is simple, safe, and avoids recurrence.

Tratamento do aneurisma aterosclerótico da artéria temporal superficial: relato de caso

ResumoAneurismas da artéria temporal superficial são incomuns segundo a literatura. A grande maioria é secundária a traumatismos ou cirurgia na região temporal, sendo que 95% dos casos evoluem para pseudoaneurismas. Entretanto, os aneurismas verdadeiros ou espontâneos são extremamente raros e representam 8% dos casos de aneurismas da artéria temporal superficial, sendo estes, geralmente, de origem aterosclerótica. Aneurismas temporais espontâneos podem coexistir com outras lesões vasculares, incluindo aneurismas intracranianos. Nosso relato trata de um paciente com aneurisma de artéria temporal superficial esquerda, de origem aterosclerótica, no qual foi realizada a excisão cirúrgica, sob anestesia geral.

Spontaneous Superficial Temporal Artery Aneurysm in a Child

Superficial temporal artery (STA) aneurysms, whether posttraumatic or spontaneous, are a rare occurrence. Herein, we present and discuss a rare case of spontaneous STA aneurysm in a child. We found <220 cases of STA aneurysms in the literature. Most of these are posttraumatic pseudoaneurysms with some characteristic diagnostic features but our case report is unique in that there was spontaneous appearance of swelling with no history of trauma. Histopathologic analysis revealed features of temporal arteritis.

Superselective Coaxial Microballoon-Occluded Coil Embolization for Vascular Disorders: A Preliminary Report

PurposeTo evaluate the safety and effectiveness of superselective coil embolization with coaxial microballoon occlusion (B-coiling) for vascular disorders. Materials and MethodsClinical data were retrospectively evaluated for 16 consecutive patients (6 men, 10 women; mean age, 70 y; age range, 57–80 y) with vascular disorders who underwent B-coiling with 0.010–0.014-inch detachable microcoils delivered through a guide-wire lumen of a microballoon catheter. Routine angiographic catheters (4–5 F) were introduced in all cases, including splenic (n = 4) and renal (n = 3) artery aneurysms, pulmonary and renal arteriovenous malformations (AVMs; n = 3 and n = 1, respectively), gastroesophageal varices (GEVs; n = 3), gastroduodenal artery stump pseudoaneurysm (n = 1), and superficial temporal artery aneurysm (n = 1). ResultsComplete primary occlusion was achieved in 87.5% of cases (n = 14) without complications. Additional percutaneous transhepatic sclerotherapy by N-butyl cyanoacrylate (NBCA)/iodized oil mixtures without balloon occlusion resulted in successful occlusion of one GEV. Additional balloon-occluded NBCA injection was successfully performed in one renal AVM. ConclusionsSuperselective coaxial microballoon embolization with detachable microcoils is a safe and useful treatment. Selective B-coiling induces tight packing under flow control in the treatment of vascular disorders.

Vasculitis of Superficial Temporal Artery in a Pediatric Patient

While superficial temporal artery (STA) vasculitis is typically a disease of the elderly, spontaneous STA aneurysm in children is anecdotic and usually caused by a subjacent vasculitis. Since 1948 around 40 cases have been listed in literature and just 6 of them under the age of 18. Three main forms have been classified: juvenile temporal arteritis, typical giant cells arteritis and temporal artery involvement secondary to systemic vasculitis. We report a rare case of STA aneurysm in an 8 year old patient already known for the surgical treatment of an aortic coarctation. The patient was asymptomatic, clinical exam was unremarkable and no traumatism, fever, arthralgias or recent infective episodes were reported. No residual coarctation at echocardiography. STA echo-colour Doppler suggested juvenile temporal arteritis, showing a dilation of 5.4 x 8.7 mm. Doppler scanning of the other districts was normal. At cerebral MRI a spindle-shaped dilation over the left STA was confirmed without other intracranial anomalies. Thoraco-abdominal angio-TC was normal to the entire aorta and at the visceral arteries level. Blood exams were unremarkable. A biopsy of the left STA was performed under general anesthesia: a true aneurysm of the artery (1.5×8 mm) was resected. At anatomopathologic examination neither epithelioid nor great cells were found but a lymphocytic infiltration was detected around the vasa vasorum. Isolated STA vasculitis in young individuals results in different findings, pathogenic triggers and clinical manifestations from affecting the elderly. Diagnosis is very important to direct the appropriate therapeutic strategy and must include histopathologic evaluation.

A traumatic superficial temporal artery aneurysm after a bicycle accident

A male cyclist presented with a swelling on the forehead. Six weeks before, he fell of his bike and smashed his head on the ground while wearing a helmet. A smooth lump of 1 cm had evolved on the temporal side of his forehead in a few weeks. Duplex ultrasonography demonstrated a dilated vessel with a minor defect in the luminal wall. Surgical exploration revealed an aneurysm of the superficial temporal artery (STA). The aneurysm was surgically removed and the patient recovered uneventfully. Owing to its superficial course, the STA is vulnerable to blunt head trauma. Traumatic aneurysms of the STA should be a differential diagnostic consideration in patients with a history of trauma and a swelling on their head.

True aneurysms of the superficial temporal artery: Diagnosis and treatment

ObjectivesTrue aneurysms arising from the superficial temporal artery (STA) are quite uncommon. The present study reviews the surgical experience with true STA aneurysms to describe the clinical features and treatment options. MethodsThis study comprised of 12 patients (6 female; mean age, 44.7 years) of spontaneous aneurysms of the STA who have undergone the surgical or endovascular treatment. All the patients had no history of trauma or surgery to the head and neck. The clinical presentation, radiographic findings, pathological and laboratory data, and treatment outcomes were retrospectively analyzed. ResultsA pulsatile and progressively growing lump in the STA area was the symptom leading to clinical attention. None neurological defects existed. Six patients had frontal lesions, two had parietal and the remaining 4 patients had preauricular region aneurysms. Imaging studies revealed that the subcutaneous mass was a saccular aneurysm accompanied by the afferent and efferent vessels. The lesions ranged in size from 8 to 23mm (mean, 11.7mm). Aneurysm trapping and excision was performed in 11 patients. Pathological examination confirmed a true aneurysm of the STA. ConclusionsTrue STA aneurysms are usually discovered as a pulsating mass over the temple and their diagnosis could be done with ultrasonography, and computed tomography and magnetic resonance angiography. Simple ligation and resection of the aneurysm is safe and curative.
