Project description:BackgroundVisceral artery pseudoaneurysm (VAPA) may result from trauma, operation, infection, inflammation, vasculitis, or malignancy. Factors associated with clinical success transarterial embolization (TAE) of VAPA have never been reported. The aim of this retrospective monocentric study was to describe clinical presentation and outcomes for patients treated for VAPA with TAE, and to identify factors associated with clinical success.MethodsWe retrospectively reviewed data from all patients referred to the University Hospital of Saint-Etienne treated with TAE for VAPA between October 2012 and January 2023. Inclusion criteria included: all patients treated by TAE for VAPA arising from branches of the coeliac trunk, superior mesenteric artery, and renal artery. We considered pre- and per-procedure clinical data, biological data, outcomes, and complications. Post-operative data included early mortality (≤30 days), repeat embolization, and complications. Predictive factors associated with clinical success were evaluated.ResultsOur sample included 89 patients (68 males). The median age was 65 [49-74] [median (Q1-Q3)] years, and the median hemoglobin level was 9 (7.6-11) g/dL. On pre-operative computed tomography (CT), active bleeding was detected in 31 (34.8%) patients. Coils were used in 58 (65.2%) procedures. Clinical success was achieved in 77 (86.5%) patients. There were 11 (12.4%) minor complications. Five (5.6%) patients died within the first 30 days. In univariate analysis, hemoglobin levels were associated with clinical success (P=0.027) and number of red blood cell (RBC) transfusions (P=0.007) and gastrointestinal bleedings (P=0.005) were associated with clinical failure. No factors were statistically significant in multivariate analysis.ConclusionsLow hemoglobin levels, high numbers of RBC transfusions, and gastrointestinal bleedings were associated with clinical failure after TAE for VAPA. Multicentre studies are needed to investigate further.

Project description:Common hepatic artery pseudoaneurysm is a rare and potentially life-threatening complication after pancreaticoduodenectomy, and the possible cause is unclear. We report a case of intraperitoneal hemorrhage after pancreaticoduodenectomy who was discharged after embolization under digital subtraction angiography. We conside that this complication may be related to iatrogenic injury.

Project description:The present study aimed to evaluate the clinical efficacy and safety of angiography and coil embolization for pseudoaneurysm post-pancreatoduodenectomy (PD). A total of 17 patients with gastrointestinal or abdominal hemorrhage after PD were included in the present study. Angiography was performed on the celiac artery, common hepatic artery, splenic artery, gastroduodenal artery and superior mesenteric artery to determine the size of the pseudoaneurysm, the parent artery and its collateral branches. A variety of embolization techniques have been applied to embolize pseudoaneurysm, including the sac packing technique, proximal embolization, exclusion technique and sandwich technique. Different techniques with coils were used for embolization and the clinical effects of embolization were analyzed. A total of 18 pseudoaneurysms were identified in 17 patients. In 2 patients, severe technical complications occurred, including migration of the coil and rupture of pseudoaneurysm, and one of them died, which may have been associated with this complication. No serious clinical complications were observed in the other patients. A total of 7 patients had mild clinical complications, including mild abdominal and dorsal pain, which were alleviated after symptomatic management. A total of 15 patients with definite pseudoaneurysm were successfully embolized without re-bleeding and complications. The clinical success rate was 94.1% (16/17). In conclusion, a variety of embolization techniques may be applied for the treatment of pseudoaneurysm after PD, which have high technical and clinical success rates and small trauma. It is recommended in emergency situations, but care should be taken to avoid serious technical complications.

Project description:ACTA2-related vasculopathy is an autosomal dominant genetic disorder characterized by aortic aneurysms and dissection, and limb artery lesions are rare. We report a case of transcatheter arterial embolization for a pseudoaneurysm of a deep femoral artery in a patient with presumptive ACTA2-related vasculopathy. A 58-year-old woman was presumed to have an ACTA2 mutation based on her history of aortic diseases and family history of ACTA2 mutations. During follow-up, contrast-enhanced computed tomography for aortic diseases revealed occlusion and vessel wall abnormalities of the bilateral deep femoral arteries. Two weeks later, she complained of acute right inguinal pain without any triggering factors, and contrast-enhanced computed tomography revealed a pseudoaneurysm of the right deep femoral artery. Vascular fragility due to ACTA2 mutation was believed to be the cause of the pseudoaneurysm. Transcatheter arterial embolization was successfully performed and no rebleeding occurred during 1.5 years after the transcatheter arterial embolization.

Project description:OBJECTIVES:The present technical article aimed to describe the efficacy of three-dimensional (3D)-printed hollow vascular models as a tool in the preoperative simulation of endovascular embolization of visceral artery aneurysms. METHODS:From November 2015 to November 2016, four consecutive endovascular treatments of true visceral artery aneurysms were preoperatively simulated with 3D-printed hollow models. The mean age of the patients (one male and three females) was 54 (range: 40-71) years. Three patients presented with splenic artery aneurysm and one with anterior pancreaticoduodenal artery aneurysm. The average diameter of the aneurysms was 16.5 (range: 10-25) mm. The 3D-printed hollow models of the visceral artery aneurysms and involved arteries were created using computed tomography angiography data of the patients. After establishing treatment plans by simulations with the 3D-printed models, all patients received endovascular treatment. RESULTS:All four hollow aneurysm models were successfully fabricated and used in the preoperative simulation of endovascular treatment. In the preoperative simulations with 3D-printed hollow models, splenic aneurysms were embolized with coils and/or n-butyl-2-cyanoacrylate to establish the actual treatment plans, and a small arterial branch originating from an anterior pancreaticoduodenal artery aneurysm was selected to obtain feedback regarding the behavior of catheters and guidewires. After establishing treatment plans by simulations, the visceral artery aneurysms of all patients were successfully embolized without major complications and recanalization. CONCLUSIONS:Simulation with 3D-printed hollow models can help establish an optimal treatment plan and may improve the safety and efficacy of endovascular treatment for visceral artery aneurysms.

Project description:A 59-year-old man received an incidental diagnosis of a 5-cm right para-aortic mass that was initially thought to be of venous origin. Multimodality imaging revealed a right bronchial artery pseudoaneurysm that was treated with endovascular embolization. Bronchial artery pseudoaneurysms are extremely rare and can be fatal if ruptured. (Level of Difficulty: Advanced.).

Project description:BACKGROUND:A thoracic aorta hematoma with branch artery pseudonaneurysm is a very rare complication of thoraric blunt trauma. The standard treatment of this type of injury is aortic endograft placement. CASE PRESENTATION:We present a case in which a thoracic aorta hematoma with branch artery pseudoaneurysm was treated with coil embolization instead of endografting. CONCLUSIONS:Coil embolization of aortic injuries may be a safe and definitive treatment alternative in selected cases. This technique has the potential to reduce the risk of procedure-related complications.

Project description:Cerebral vascular malformations constitute one of the key abnormalities in children with PHACE syndrome, which is characterized by Plaque like cutaneous hemangiomas, Posterior fossa abnormalities, arterial Cerebrovascular and Eye abnormalities, with or without Sternal clefts (PHACES when sternal clefts are present), and associated midline anomalies. Both moyamoya arteriopathy and intracranial aneurysms have been reported in children with this syndrome. Herein, we report the successful treatment of a growing left posterior-communicating artery aneurysm arising from an aberrant left internal carotid artery (LICA) with balloon assisted coiling (BAC) in a child with PHACE syndrome. We circumvented the limitations posed by the narrow caliber of the proximal LICA, by successfully navigating a coiling microcatheter from the basilar artery into the LICA via a persistent trigeminal artery. BAC was then achieved using a Scepter Mini balloon microcatheter for aneurysm neck remodelling.
