Appropriateness of care in superficial venous disease.

Chronic superficial venous disease, including superficial venous insufficiency, superficial venous thrombosis, and aneurysms, are prevalent conditions that affect millions of individuals worldwide. With chronic venous insufficiency specifically, the advent of office-based minimally invasive procedures in recent decades has significantly expanded access to outpatient treatment. However, as venous insufficiency is rarely life- or limb-threatening, the clinical diagnosis, diagnostic evaluation, and treatment indications should be considered carefully when recommending elective intervention. Appropriateness of care guidelines intend to aid providers and patients in the decision-making process, based on the available evidence in the scientific literature, to select the best care for the patient when treating their superficial venous disease.

[Single Center Experience in Surgical Treatment of Extracranial Supra-Aortic Aneurysms].

Objective To evaluate the effect of surgical treatment on extracranial supra-aortic aneurysms and summarize the experience. Methods The clinical data of 10 patients undergoing surgical treatment of extracranial supra-aortic aneurysms from May 2019 to November 2023 in the Department of Vascular Surgery of Beijing Tiantan Hospital affiliated to Capital Medical University were collected.The 10 patients included 5 patients with internal carotid artery aneurysm,2 patients with subclavian artery aneurysm,2 patients with vertebral artery aneurysm,and 1 patient with internal carotid artery aneurysm combined with ipsilateral subclavian artery aneurysm.The surgical indications,surgical regimens,clinical efficacy,and complications were retrospectively analyzed. Results All the 10 patients underwent surgery successfully,with the surgery duration range of 60-420 min and the median surgery duration of 180.0 (121.5,307.5) min.Intraoperative bleeding volume varied within 30-400 mL,with a median of 90 (50,125) mL.The time of carotid artery blocking and vertebral artery blocking varied within the ranges of 10-20 min and 20-30 min,with the medians of 15.0 (11.5,16.3) min and 25.0 (15.0,22.5) min,respectively.No cardiac accident,cerebral infarction,or cerebral hemorrhage occurred during the perioperative period.The 10 patients were followed up for 3-58 months,with the median follow-up time of 8.5 (5.3,17.0) months.One patient with subclavian artery aneurysm developed artificial vessel occlusion 20 months after surgery.One patient with internal carotid artery aneurysm developed distal carotid artery stenosis 6 months after surgery. Conclusion Surgical treatment should be actively adopted for extracranial supra-aortic aneurysms,and individualized surgical regimens should be designed according to patient conditions.

Invasive treatment for extracranial carotid artery aneurysm: a single-center case series and literature review.

BACKGROUND: Extracranial carotid artery aneurysm (ECAA) is a rare peripheral arterial disease. The main treatment strategies include conservative treatment, open surgery, endovascular treatment, and hybrid techniques, and there is no expert consensus or guidelines, with only a few case reports. METHOD: This article reviewed 10 cases diagnosed with "extracranial carotid artery aneurysm" and received invasive treatment from January 2013 to July 2023 in our medical center. RESULTS: There were 10 patients with ECAA admitted to our center, including seven cases of true aneurysms, two cases of pseudoaneurysms, and one case of dissecting aneurysm. There were 3 females and 7 males aged between 24-61 years. Based on the characteristics of ECAA, we designed the individualized procedure including open surgery, endovascular treatment, and hybrid treatment. Procedures were technically successful for all patients, and none of them had any adverse events during the follow-up period except for one patient who developed cerebral hemorrhage on the third postoperative day and recovered after cerebral puncture and drainage. CONCLUSION: The current invasive treatments for ECAA mainly include open surgery, endovascular treatment, and hybrid treatment, and they all appear to be safe and effective.

[Open Surgery for Right Subclavian Artery Aneurysm with Infective Endocarditis:Report of a Case].

Subclavian artery aneurysm is usually rare. We report a case of a right subclavian artery aneurysm with infective endocarditis. A 36-year-old woman was admitted at our hospital due to a cerebral embolism. The echocardiogram showed severe mitral regurgitation with vegetation, and computed tomography (CT) revealed an intrathoracic right subclavian artery aneurysm. The 59×39 mm-sized mass was located distal to the vertebral artery. Mitral valvuloplasty, tricuspid annuloplasty, and aneurysm surgery with extra-anatomical bypass were performed simultaneously. The aneurysm was resected through a median sternotomy and right supraclavicular and subclavicular incisions. Revascularization with transthoracic aorto-axillary extra-anatomical bypass was also performed. The postoperative course was uneventful with no noted complications.

Endovascular Treatment of Unruptured Pancreatic Arcade Aneurysms.

PURPOSE: This study aimed to assess the safety and efficacy of endovascular treatment of unruptured pancreatic arcade aneurysms in a single-center series. MATERIALS AND METHODS: The electronic medical records of patients who underwent endovascular treatment for unruptured pancreatic arcade aneurysms between 2011 and 2022 at our tertiary center were retrospectively reviewed. The presence of celiac artery stenosis/occlusion; aneurysm number, location, and size; endovascular technique; procedure-related complication incidence; and clinical outcomes were assessed. RESULTS: Twenty-three patients (12 men and 11 women; mean [range] age, 63.8 [45-84] years) with 33 unruptured pancreatic arcade aneurysms were identified. Celiac artery stenosis/occlusion coexisted in 17 (74%) patients. Five (21%) patients had multiple aneurysms. The median aneurysm size was 9.3 mm (range, 4-18 mm). Seven, 6, 6, 5, 4, 3, and 2 aneurysms were located in the gastroduodenal, dorsal pancreatic, anterior superior pancreaticoduodenal, inferior pancreaticoduodenal, posterior inferior pancreaticoduodenal, posterior superior pancreaticoduodenal, and anterior inferior pancreaticoduodenal arteries, respectively. Four (15%) and 22 (85%) aneurysms were treated with endosaccular packing alone and coil embolization with endosaccular packing and parent artery occlusion, respectively, with resulting exclusion from arterial circulation. The remaining 7 aneurysms coexisting with larger aneurysms in other peripancreatic arteries were observed without embolization because they were small and for preserving collateral blood flow to the celiac artery. The treated aneurysms did not rupture or recur during the follow-up period (median, 40 months). CONCLUSION: Endovascular treatment is a safe and effective treatment for unruptured pancreatic arcade aneurysms. LEVEL OF EVIDENCE: 3, non-controlled retrospective cohort study.

[Thoracoscopic resection of azygos vein aneurysm]. / Torakoskopicheskoe udalenie anevrizmy dugi neparnoi veny. Redkoe klinicheskoe nablyudenie.

Azygos vein aneurysm is a rare thoracic disease that often mimics posterior mediastinum tumors. Pathogenesis of azygos vein aneurysm is unclear. Discussions about possible causes are still ongoing. Most aneurysms are asymptomatic and diagnosed incidentally during standard examinations. Severe complications of azygos vein aneurysm include rupture with massive bleeding and pulmonary embolism. Contrast-enhanced chest CT and MRI are essential. Differential diagnosis includes tumors, cysts and rare neoplasms of the mediastinum. Treatment algorithm is not established. There are traditional surgical and endovascular methods. We present minimally invasive surgical treatment of azygos vein aneurysm in a 53-year-old woman. The patient underwent thoracoscopic resection of aneurysm. Histological examination revealed a partially thrombosed azygos vein aneurysm.

Surgical Intervention for Giant Pulmonary Artery Aneurysm in Behcet Disease: A Case Report.

BACKGROUND Pulmonary artery aneurysm (PAA), defined as a pathologic dilatation of the PA greater than 1.5-fold the normal diameter, is a rare complication of Behçet disease. It is due to a weakening of the vessel wall for a great vessels' vasculitis, often asymptomatic and incidentally diagnosed on imaging studies. However, if ignored, it can lead to life-threatening complications such as rupture and massive hemoptysis. We report the case of a giant fast-growing PAA in a young patient with a history of Behçet disease in which an inadequate follow-up and poor patient information could had led to life-threatening complications. CASE REPORT A 37-year-old man with a history of Behçet disease presented to our Emergency Department with hemoptysis due to a right inferior lobar artery aneurysm measuring 52×33 mm. The aneurysm was detected years before, measuring 18 mm, but the patient and physicians missed the subsequent follow-up. After several attempts at embolization, the multidisciplinary board suggested to proceed with surgical intervention. Surgery was performed with an extracorporeal circulation system kept on stand-by due to the high hemorrhagic risk. By opening the fissure, the dilatation of the inferior lobar artery was clearly identified up to the origin of the middle lobar branch. Thus, a lower-middle bilobectomy was performed after the introduction of a suction cannula in the aneurysm, which facilitated its emptying and the subsequent maneuvers. CONCLUSIONS PAA is a rare disease, generally treated with medical therapy or interventional procedures. However, giant and fast-growing aneurysms are more likely to entail complications and often required immediate treatment. In this case, primary surgical intervention with a pulmonary bilobectomy appeared mandatory to avoid life-threatening events.

Superficial temporal artery aneurysm misdiagnosed in a patient with long-term migraine headache treatment: a case report.

BACKGROUND: Superficial temporal artery aneurysm is a rare vascular abnormality without specific clinical symptoms. In this case report, we present the case of a patient with superficial temporal artery aneurysm who was diagnosed with migraine headache at first. CASE PRESENTATION: A 60-year-old Iranian man with a previous history of headaches, who did not respond properly to the treatments following the initial diagnosis of migraine, presented with a painless lump in the left temporal region, and he was diagnosed with superficial temporal artery aneurysm via Doppler ultrasound. Finally, surgical removal of the left superficial temporal artery aneurysm was performed. CONCLUSIONS: This case shows the importance of vascular causes in the approach to headache etiologies, especially when the headache is prolonged without proper responses to treatment. Computed tomography angiography and magnetic resonance angiography are appropriate diagnostic methods for aneurysm detection that should be considered in future studies.

Aneurisma esplénico como hallazgo incidental durante el embarazo: a propósito de un caso / Splenic aneurysm as an incidental finding during pregnancy: a case report

El embarazo, especialmente el tercer trimestre, incrementa notablemente el riesgo de rotura de los aneurismas esplénicos. Cuando esto ocurre, se desencadena un cuadro clínico grave manifestado principalmente como un dolor abdominal agudo acompañado de inestabilidad hemodinámica. A pesar de la gran morbimortalidad tanto materna como fetal que esto conlleva, no existe hoy en día consenso sobre su manejo óptimo. Se presenta el caso de una secundigesta a la que se diagnostica de manera incidental un aneurisma en la arteria esplénica durante el segundo trimestre de gestación. Tras confirmarse dicho diagnóstico mediante resonancia magnética, se decide realizar una esplenectomía programada vía laparotómica en semana 24+2. La evolución maternofetal posterior fue favorable hasta la semana 40 en la que se produjo un parto eutócico. Los aneurismas esplénicos deben tratarse en todas las gestantes, independientemente de su tamaño o sintomatología, pues el beneficio supera los riesgos que supone una cirugía programada.

Pregnancy, especially the third trimester, significantly increases the risk of splenic aneurysm rupture. When this occurs, it results in a severe clinical presentation primarily characterized by acute abdominal pain accompanied by hemodynamic instability. Despite the substantial maternal and fetal morbidity and mortality associated with this condition, there is currently no consensus on its optimal management. We present the case of a second-time pregnant woman who incidentally received a diagnosis of a splenic artery aneurysm during the second trimester of gestation. After confirming this diagnosis through magnetic resonance imaging, it was decided to perform a scheduled laparotomic splenectomy at 24+2 weeks of gestation. Subsequent maternal and fetal evolution was favorable until the 40th week when a eutocic delivery occurred. Splenic aneurysms should be treated in all pregnant women, regardless of their size or symptomatology, as the benefits outweigh the risks associated with elective surgery.

Deciphering Popliteal Artery Aneurysm Patient Diversity: Insights From a Cluster Analysis of the POPART Registry.

BACKGROUND: Popliteal artery aneurysms (PAAs) are the most common peripheral aneurysm. However, due to its rarity, the cumulative body of evidence regarding patient patterns, treatment strategies, and perioperative outcomes is limited. This analysis aims to investigate distinct phenotypical patient profiles and associated treatment and outcomes in patients with a PAA by performing an unsupervised clustering analysis of the POPART (Practice of Popliteal Artery Aneurysm Repair and Therapy) registry. METHODS AND RESULTS: A cluster analysis (using k-means clustering) was performed on data obtained from the multicenter POPART registry (42 centers from Germany and Luxembourg). Sensitivity analyses were conducted to explore validity and stability. Using 2 clusters, patients were primarily separated by the absence or presence of clinical symptoms. Within the cluster of symptomatic patients, the main difference between patients with acute limb ischemia presentation and nonemergency symptomatic patients was PAA diameter. When using 6 clusters, patients were primarily grouped by comorbidities, with patients with acute limb ischemia forming a separate cluster. Despite markedly different risk profiles, perioperative complication rates appeared to be positively associated with the proportion of emergency patients. However, clusters with a higher proportion of patients having any symptoms before treatment experienced a lower rate of perioperative complications. CONCLUSIONS: The conducted analyses revealed both an insight to the public health reality of PAA care as well as patients with PAA at elevated risk for adverse outcomes. This analysis suggests that the preoperative clinic is a far more crucial adjunct to the patient's preoperative risk assessment than the patient's epidemiological profile by itself.

A rare case of a simultaneous post-dissection saccular aneurysm of the ascending aorta and large pulmonary artery aneurysm with secondary embolism: a case report.

BACKGROUND: Aneurysms of the pulmonary arteries and the ascending aorta are rare, and both bear a high mortality risk if left untreated. In general, these entities are primarily caused by etiologies such as hypertension, pulmonary arterial hypertension, infection or congenital disorders. Treatment requires a rapid diagnostic work-up or even immediate surgical intervention in acute cases. Nevertheless, surgery entails serious perioperative risks, in particular in patients with multiple comorbidities. CASE PRESENTATION: We discuss a 70-year-old woman presented with decompensated heart failure based on severe pulmonary artery hypertension, coincided by a massive pulmonary artery aneurysm with secondary embolism. Additional diagnostic imaging also showed a chronic post-dissection, saccular aneurysm of the ascending aorta. To our knowledge, this simultaneous diagnosis of a saccular aneurysm of the ascending aorta and a large aneurysm of the pulmonary artery with secondary embolism has not yet been described. Nonetheless, conservative treatment was chosen due to extensive pulmonal and cardiovascular comorbidities and the high-risk profile of surgery. CONCLUSIONS: Extensive aneurysmatic disease of the pulmonary arteries and ascending aorta come with a serious burden of disease, especially if coincided by severe pulmonal and cardiovascular comorbidities. Both conditions can be curatively treated by surgical intervention. However, in every case the risk of surgery and the patient's vitality, comorbidities and wishes should be taken into account to formulate an adequate treatment plan. Therefore, shared decision making is of utter importance.

Compression syndrome of distal peripheral aneurysms of the upper limb.

True aneurysm of the radial artery is very rare. Aneurysmal expansion of arteries due to degenerative changes, possibly infections, primarily affects the abdominal and thoracic aorta, intra and extracranial sections of cerebral arteries, popliteal artery, and visceral arteries. Published literature does not address the aneurysm on the distal sections of the arteries of upper or lower limb. Unlike the classic symptoms of aneurysmally altered arteries such as rupture, thrombosis and embolization, we encounter more often vascular compression syndrome in distal peripheral aneurysms. We demonstrate the case management of a patient with over 20 years increasing wrist resistance. A fusiform aneurysm of the distal section of the radial artery was identified by sonography. Under general anesthesia, we performed aneurysm resection and artery reconstruction using an interpositum from the ipsilateral cephalic vein. The histological examination of the resected tissue confirmed the presence of all three layers of the vascular wall, confirming the true aneurysm of the radial artery. No complications developed in the patient in the postoperative period and all problems related to the aneurysm subsided (Fig. 4, Ref. 23). Keywords: aneurysm, arteria radialis, surgical reconstruction.

Treatment strategy for splenic artery aneurysms and novel classification based on imaging.

OBJECTIVE: The incidence of splenic artery aneurysms (SAAs) has increased with advances in imaging techniques, necessitating a comprehensive classification to guide treatment strategies. This study aims to propose a novel classification system for SAAs based on aneurysm characteristics and to review treatment outcomes at our center. METHODS: This retrospective study included 113 patients with SAAs admitted to Peking Union Medical College Hospital from January 2019 to December 2023, assessed using computed tomography angiography or digital subtraction angiography. A new classification system was devised based on the aneurysm location, morphology, integrity, and parent artery anatomy. Treatment strategies were determined based on these characteristics, with interventions ranging from endovascular therapy to laparoscopic and open surgery. Patients were followed up after the intervention to assess mortality, complications, reinterventions, and aneurysm-related outcomes. RESULTS: The study cohort of 113 patients with 127 SAAs had a predominance of female patients (63.7%) and a mean age of 52.7 years. The SAAs were classified into five types, with type I being the most common. The intervention techniques varied across types, with sac embolization, covered stent implantation, and artery embolization being the most frequently used. The overall technical success rate was 94.7%, with perioperative complication and reintervention rates of 25.0% and 0.9%, respectively, and no deaths within 30 days after the intervention. The median follow-up duration was 21 months, with overall complications rate of 3.5% and no aneurysm-related complications or deaths. CONCLUSIONS: The proposed classification system effectively guides the selection of treatment strategies for SAAs, incorporating key anatomical and morphological features. This system facilitated high technical success and low complication rates, underscoring the importance of tailored techniques in managing SAAs.

Disappointing results of popliteal aneurysm endovascular treatment with a new self-expandable covered stent.

PURPOSE: To describe our clinical experience of endovascular exclusion of popliteal artery aneurysms using the new self-expandable covered stent SOLARIS® (Scitech Medical, Brazil), and to report its results in the context of surgical and endovascular treatment of popliteal artery aneurysms. CASE REPORT: Among 20 popliteal artery aneurysms undergoing open or endovascular repair in 2022 and 2023, two patients were successfully treated with the Solaris stentgraft. Both patients had a patent popliteal artery and three run-off vessels. After stentgraft implantation, they received dual antiplatelet therapy for three months and they were followed-up with Duplex scan and clinical evaluation after three months, and every six months thereafter. After three months, one Solaris stentgraft had complete thrombosis and the other ruptured, requiring surgical removal. No complications were observed among the other aneurysms treated with open repair or with the Viabahn® stentgraft. CONCLUSIONS: Endovascular treatment of popliteal aneurysms with the new covered self-expandable stent Solaris resulted in severe complications in the two cases reported, and in worse short-term outcomes than endovascular repair with Viabahn® and open repair. Its off-label use to treat popliteal artery aneurysms should be therefore discouraged.

Deceased Donor Liver Transplantation With Hepatic Artery Aneurysm.

Few case reports have documented the long-term outcomes of liver donor aneurysms, illustrating the apprehension of transplant surgeons about using these grafts. However,the presence of an aneurysm in the donor liver should not be an absolute contraindication for its use. As shown in our described patient, such grafts have the potential to achieve good results.

Factors contributing to patency after aneurysmorrhaphy and outflow repair in arteriovenous fistula aneurysm treatment.

INTRODUCTION: Vascular access-related aneurysms (VARA) are a complication of arteriovenous fistulas. Repair techniques have been described in the literature with varied outcomes. MATERIALS AND METHODS: We conducted a prospective cohort study on patients who had VARA repair over 41 months. The indication for repair was an aneurysmal arteriovenous fistula (AVF) at risk of haemorrhage or difficulty in cannulation. Pseudoaneurysms, infected AVF and bleeding VARA were excluded. All patients underwent outflow stenosis treatment when present, followed by aneurysmorrhaphy. They were monitored periodically over 12 months, measuring functional primary and cumulative patency and access flow. We studied the patient demography, access flow and presence of outflow stenosis. Access flow was measured from the brachial artery (Qa) as a surrogate using ultrasonography. A Kaplan-Meier survival analysis was used to predict the primary and cumulative patency at 12 months and factors contributing to 12-month patency were analysed. RESULTS: A total of 64 patients were recruited for this study, of whom 58 completed the study. Most of the participants were male (67%) with a median age of 45 years. Forty-six patients (79.3%) had brachiocephalic fistula (BCF) aneurysms. Thirty-nine (67.2%) had preexisting outflow stenoses that required intervention. All patients underwent an aneurysmorrhaphy, of whom 12% had a cephalic arch vein transposition due to severe stenosis. Primary patency at 12 months was 86%, whereas the cumulative patency rate was 95%. Patency was significantly associated with younger age and showed a positive trend with higher preintervention Qa. Symptomatic recurrent stenosis developed in 17.2% of the cohort. CONCLUSION: Improving the patency of VARA entails the treatment of outflow stenosis and aneurysmorrhaphy. Surveillance is important to detect and treat recurrent outflow stenoses. The outcome is better among younger patients with pre-interventional access flow as measured in the brachial artery as a surrogate.

Resection of a retroperitoneal lumbar vein aneurysm: A case report.

We present a rare case involving a 54-year-old man with a history of pancreatitis who developed a retroperitoneal lumbar vein aneurysm that was initially misidentified as a pancreatic pseudocyst. Subsequent imaging revealed an enlarged mass and retroperitoneal perforation. Despite initial hesitation, the patient eventually underwent radical surgery that enabled the successful removal of the mass, which was near the inferior vena cava. Pathological examination confirmed varicose veins, and the final diagnosis was lumbar vein aneurysm in the retroperitoneum. The patient's postoperative recovery was uneventful, with no symptoms or recurrence observed on 6-month follow-up imaging. We investigated a potential link between pancreatitis and recurrent bleeding due to weakened venous walls. The findings from this case underscore the rarity of venous aneurysms and the diagnostic and treatment challenges due to the limited number of cases; furthermore, they emphasize that surgery should be carefully considered based on the lesion location and associated risks.
