[Percutaneous treatment of post-acute myocardial infarction mechanical complications: state of the art]. / Trattamento percutaneo delle complicanze meccaniche dell'infarto miocardico acuto: stato dell'arte.

Left ventricular free wall rupture, ventricular pseudoaneurysm, papillary muscle rupture and ventricular septal rupture are life-threatening mechanical complications of acute myocardial infarction. Despite significant improvements over the last decades in overall mortality for patients with myocardial infarction, the outcome of subjects who develop post-infarction mechanical complications remains poor. Surgical treatment is considered the standard of care. However, percutaneous approaches (such as pericardial fibrin-glue injection for left ventricular free wall rupture, transcatheter edge-to-edge mitral repair for papillary muscle rupture and device closure for ventricular pseudoaneurysm or septal rupture) have been proposed in selected high-risk or inoperable patients, or in subjects with ideal characteristics for feasibility, as therapeutic alternatives to open surgery. The aim of the present review is to provide a comprehensive overview of the percutaneous strategies for the management of post-acute myocardial infarction mechanical complications.

Postpartum hemoperitoneum - A rare case of uterine artery pseudoaneurysm rupture after uncomplicated vaginal delivery.

OBJECTIVE: Our aim is to demonstrate a rare cause of hemoperitoneum without vaginal bleeding resulting from the rupture of a uterine artery pseudoaneurysm after uncomplicated vaginal delivery. CASE REPORT: A 39-year-old woman who had experienced a normal vaginal delivery 8 days previously to being seen in our hospital, was presented to the emergency room with hypovolemic shock. Computed tomography angiography (CTA) showed massive internal bleeding and a ruptured pseudoaneurysm arising from the left uterine artery. The patient was successfully treated through transcatheter arterial embolization (TAE). CONCLUSION: A pseudoaneurysm is a rare disease which can occur during an uncomplicated vaginal delivery. The clinical presentation can vary from asymptomatic, vaginal bleeding or hemoperitoneum. The diagnosis can be made by using Doppler sonography, CTA or Magnetic Resonance Imaging. The use of TAE is now the most common treatment option and possesses a high success rate.

Iatrogenic pseudoaneurysm after bone biopsy managed with endovascular coil embolisation.

Bone marrow biopsy (BMB) is a routinely performed procedure, with the preferred site being the posterior superior iliac crest. Uncommonly, it may be complicated by haemorrhagic complications, especially in patients with coagulopathy. Here, we present a case of pelvic haematoma following a BMB due to the injury of the right internal iliac artery. Endovascular embolisation was performed on an urgent basis to manage this complication. The bleeding stopped following the embolisation.

Aortic Pseudoaneurysm-Related Acute Ortner's Syndrome Presenting as Sudden Hoarseness: A Case Series.

BACKGROUND Ortner syndrome, or cardiovocal syndrome, is a left recurrent laryngeal nerve palsy secondary to cardiovascular causes. Aortic pseudoaneurysm is a rare life-threatening condition resulting from weakening of the aortic wall. Clinical presentation of aortic pseudoaneurysm is highly variable. Hoarseness is often caused by benign conditions; however, it can be the first symptom of an underlying serious condition requiring immediate diagnosis and management. CASE REPORT We report a series of 2 patients with sudden hoarseness as the first symptom of an aortic arch pseudoaneurysm. Two men, with ages of 76 and 60 years, had sudden hoarseness a few weeks before. Laryngoscopy showed a left vocal cord palsy in both cases. A computed tomography (CT) scan showed a thoracic aortic pseudoaneurysm located at the aortic arch compressing the left recurrent laryngeal nerve. Both patients were treated with endovascular aortic repair. The first patient underwent a carotid-subclavian artery bypass, and the left subclavian artery was closed with a vascular plug device. He was discharged a week later, with persistent hoarseness. In the second case, subclavian artery occlusion and pseudoaneurysm embolization with coils were performed. Control CT scan confirmed the procedure's success. However, after an initial favorable evolution, the patient had severe non-vascular complications and finally died. CONCLUSIONS Considering these 2 cases and those reported in the literature, aortic origin should be considered in the differential diagnosis of hoarseness, particularly when it appears suddenly. Thoracic endovascular aortic repair is a feasible option for those patients with penetrating aortic ulcer or pseudoaneurysm located in the aortic arch.

Endovascular embolisation of a traumatic pseudoaneurysm of the lateral perforating peroneal artery.

Pseudoaneurysm of the lateral perforating branch of the peroneal artery is exceedingly rare. To our knowledge, eight cases are described in the current literature, with five occurring as a result of trauma and the remainder being iatrogenic. We present a pseudoaneurysm of the lateral perforating peroneal artery in a professional athlete following an inversion-plantarflexion injury of the ankle. He described persistent pain and fluctuant swelling to the lateral aspect of the right ankle with sudden onset of increased pain and swelling 10 days after the initial injury. Arterial duplex identified a pseudoaneurysm of the right lateral perforating peroneal artery. Endovascular coil embolisation of the aneurysm resulted in almost immediate improvement in symptoms. The patient has since regained full function of the affected ankle. This case report highlights the necessity for clinicians to maintain a high index of suspicion in order to promptly investigate and appropriately manage this pathology.

Tuberculous aortitis with jejunal artery mycotic pseudoaneurysm managed by endovascular coil embolisation.

Mycotic aneurysm in a visceral artery due to tuberculosis (TB) is a rare occurrence. Imaging plays a critical role in its diagnosis. Over the last few years, minimally invasive interventional radiological treatment has replaced more invasive surgical procedures. Here, we report a case presenting with abdominal pain, diagnosed with jejunal artery mycotic pseudoaneurysm (PSA) secondary to TB, managed by endovascular coiling. Coil embolisation of the superior mesenteric artery branch was done using three coils, closing both the front door, back door and sac of the mycotic aneurysm. Visceral PSA following TB infection is rare and can be fatal if left untreated. Coil embolisation is a minimally invasive procedure with a high success rate and comparatively fewer complications.

Formation of a Pseudoaneurysm after a .22 Caliber Bullet Embolized to the Left Femoral Artery: A Case Report.

Bullet embolization is a rare and potentially life-threatening complication of gunshot wounds, particularly in lowpowered and small-caliber bullets. When these small bullets enter a large elastic vessel, they have the potential to leave a small entrance hole that can form a traumatic pseudoaneurysm. These pseudoaneurysms, which may be life-protecting at first, may rupture and lead to exsanguination if not found. We report an interesting case of an 18-year-old male gunshot victim where a bullet formed an aortic pseudoaneurysm and subsequently embolized and present a review of the literature regarding bullet embolization and traumatic pseudoaneurysms.

A combined endovascular and open repair of innominate artery bifurcation pseudoaneurysm: a case report.

BACKGROUND: Innominate artery aneurysms (IAAs) are rare and may result in rupture, distal arterial embolization, or local compression without timely treatment. Rupture is the most dangerous of these complications. This article reports a case of innominate artery bifurcation pseudoaneurysm. CASE PRESENTATION: The patient was a 45-year-old man who was admitted to the emergency department due to chest discomfort. The computed tomographic angiography (CTA) imaging indicated the presence of a 3.6*2.4 cm saccular aneurysm in the bifurcation of the innominate artery, involving both the right proximal subclavian and common carotid arteries. The patient's vital signs were normal, there was equal blood pressure in the upper arms and no neurological dysfunction was observed. Gadolinium-enhanced magnetic resonance angiography indicated that the circle of Willis was intact. The treatment involved open surgery combined with endovascular therapy. The external carotid artery was first transposed to the right subclavian artery (RSA) and an 8-mm woven Dacron graft was inserted in the middle. The covered stent graft was then placed in the proximal part of the innominate artery to close the entrance of the aneurysm. Lastly, an occluder was implanted at the origin of the RSA. There were no perioperative or postoperative complications. At 1-year follow-up, no aneurysm was observed on CTA and the right vertebral artery was patent. CONCLUSIONS: This study indicated that the combined use of endovascular therapy and open repair surgery is an effective strategy to treat innominate artery bifurcation pseudoaneurysm.

Giant splenic artery pseudoaneurysm with arteriovenous fistula: diagnostic challenges and interdisciplinary treatment considerations.

We present a compelling case of an elderly male with a complex medical history who presented with sepsis secondary to a urinary tract infection. During admission, changes in his abdominal exam prompted imaging studies, which revealed a grade IV splenic laceration with a giant splenic artery pseudoaneurysm containing a suspected arteriovenous fistula component. Multidisciplinary discussion was had regarding patient management which resulted in the decision to perform an emergent splenectomy. Learning points from this case underscore the crucial role of interdisciplinary collaboration in the treatment of this pathology. Additionally, we discuss the decision-making process to support surgical intervention in the absence of clear guidelines in this exceedingly rare condition.

Hemorrhagic shock from gastric pseudoaneurysm post-percutaneous endoscopic gastrostomy: a case report.

Percutaneous endoscopic gastrostomy (PEG) is widely used for long-term enteral nutrition in patients unable to maintain adequate oral intake. Despite advancements in PEG techniques, complications remain a concern. We report a case of a 94-year-old bedridden man who developed significant complications after PEG placement using the pull method. Initially, minor bleeding at the puncture site was managed using traction compression. However, the patient later experienced hemorrhagic shock owing to pulsatile bleeding around the gastrostomy site. Despite attempts to control the bleeding through traction and transfusions, a pseudoaneurysm adjacent to the PEG button was identified. The patient underwent successful transcatheter arterial embolization (TAE). Post-TAE, no further bleeding or hematoma was observed, and imaging confirmed the resolution of the pseudoaneurysm and hematoma. Methicillin-resistant Staphylococcus aureus (MRSA) infection was detected at the gastrostomy site, which contributed to complications. Despite successful management of the bleeding, the patient's overall condition deteriorated, and he died on postoperative day 66. This case underscores the importance of vigilant monitoring and management of PEG-related complications, particularly infections that may precipitate severe vascular events.

Gastric band removal: mind the arterial anastomoses!

Bariatric surgery may sometimes be challenging and may lead to severe complications. Surgical re-intervention in such cases is not the preferred option due to co-morbidities. When severe bleeding occurs, embolization of the lacerated vessels is the preferred minimal invasive management option and needs to be available if possible. We would like to report a case of young patient who underwent severe bleeding after migration of a gastric band. The patient was successfully embolized and the band was removed. However, on the second post-operative day, the patient complained again for acute abdominal pain and turned haemodynamically unstable. Fresh blood was aspirated from the surgical drain. A new emergency CT scan was performed and a new large pseudoaneurysm was revealed taking origin from the left gastric artery. The second bleeding occurred due to an anastomotic communication and was also successfully embolized. The main take home messages are that bariatric surgery may lead to several complications including bleeding, gastric band may cause vessel erosion but also offer a tamponade effect, endovascular embolization of the lacerated vessels is the preferred management and pseudoaneurysms arising in hepato-splenic or gastroduodenal arteries should be treated with the sandwich embolization technique.

Treatment of uterine artery (pseudo)aneurysm during pregnancy: A case report and review of the literature.

PURPOSE: To describe the management of uterine artery (pseudo)aneurysm, ruptured or unruptured, during pregnancy. METHODS: After reporting a case about this rare pathology, a review of the literature was performed. The search was applied to PubMed databases. RESULTS: A total of eighteen articles met the inclusion criteria. Eighteen patients were reported. Eight (44.4 %) patients didn't have prior medical or surgical history. Fifteen (83.3 %) beneficed interventional radiology method during pregnancy including two cases (13.3 %) with repeated embolization because of recanalization of the (pseudo)aneurysm. Nine patients (50 %) beneficed a planned cesarean between 34 and 39 weeks of gestation. One (15.8 %) patient was diagnosed with fetal death before treatment of the uterine artery (pseudo)aneurysm. CONCLUSION: The decision to proceed to the treatment of the (pseudo)aneurysm must consider several factors, associated or not with a good fetal vitality and a hemodynamically stable patient. Embolization appears to be the method of choice. Mode of delivery and term remain not clear and contraindication of expulsive efforts in case of a uterine artery (pseudo)aneurysm merit further investigations.

Endovascular treatment of aorta-iliac arterial pseudoaneurysm caused by Brucella.

We aimed to analyze the feasibility of endovascular treatment for brucellosis-related aorta-iliac artery pseudoaneurysm. We did a statistical analysis that among the 11 cases, the thoracic aorta was involved in 3 cases, the abdominal aorta was involved in 6 cases, and the iliac artery was involved in 2 cases. Five patients had a history of contact with cattle and sheep, 3 had a history of drinking raw milk, 10 patients had a fever before the operation, and 11 patients had positive serum agglutination test. Blood culture was positive in 2 patients. All patients were given anti-brucellosis treatment immediately after diagnosis. One died of aortic rupture 5 days after emergency endovascular gastrointestinal bleeding. Endovascular-covered stent implantation and active anti-brucellosis therapy were used to treat 10 patients. The follow-up period was 8 years without aortic complications or death for all patients. We think early diagnosis and a combination of anti-brucellosis drugs and endovascular therapy may be the first choice for treating the pseudoaneurysm caused by Brucella.

Splenic artery embolization complicated by pleural effusion.

This case report and review describes a 31-year-old man with a history of chronic pancreatitis who presented to the hospital with shortness of breath and left-sided chest pain. Three days prior, he underwent mid-splenic artery embolization due to hematemesis attributed to a splenic artery pseudoaneurysm associated with a peripancreatic pseudocyst. Upon this presentation, the patient reported increasing shortness of breath, left-sided pleuritic chest pain, and epigastric and left upper quadrant abdominal pain. Imaging revealed left pleural effusion, splenic infarcts, and adjacent fluid collections. Thoracentesis confirmed an exudative effusion. The pleural effusion was attributed to recent splenic artery embolization, and the patient was discharged on appropriate medications in stable condition on the sixth day of hospitalization. This case underscores the importance of considering embolization-related complications in the differential diagnosis of pleural effusions following such procedures. The etiology, diagnosis, and management of splenic artery aneurysms are discussed in this review.

Ruptured pseudoaneurysm in a biliary metallic stent in a patient with pancreatic cancer: a case report.

We report a case of an 87 year-old woman who was admitted with jaundice, but had no pain or fever. Contrast-enhanced computed tomography revealed a tumor in the head of the pancreas, which caused distal malignant biliary obstruction. Initial transpupillary drainage by endoscopic retrograde cholangiopancreatography (ERCP) was difficult due to severe biliary stricture caused by the tumor, but cannulation of the pancreatic duct was successful. Pancreatic ductal adenocarcinoma was revealed through cytologic examination of pancreatic juice and the patient underwent percutaneous transhepatic biliary drainage (PTBD). 16 days after the jaundice was resolved, an uncovered Zilver® metallic stent was successfully deployed using a guidewire from the PTBD route, and the patient was discharged with palliative care due to advanced age. However, 54 days after discharge, the patient presented with black vomiting and recurrent jaundice. ERCP revealed an obstructed stent with black debris, and further evaluation revealed a ruptured pseudoaneurysm that branched off the gastroduodenal artery within the metallic biliary stent. Angiography revealed that embolization was successful. The patient recovered and was discharged without further episodes.

Incidence of pseudoaneurysm after follow-up computed tomography for nonoperatively managed splenic injury: Systematic review.

BACKGROUND: The aim of this systematic review was to assess the estimated incidence of pseudoaneurysm (PSA) with follow-up computed tomography (CT) for adult splenic injury with nonoperative management (NOM). METHODS: A systematic literature search was conducted in MEDLINE, Central, CINAHL, Clinical Trials, and ICTRP databases between January 1, 2010, and December 31, 2023. Quality assessment was performed using the Risk of Bias in Non-randomized Studies of Exposures (ROBINS-E) tool. Adult splenic injury patients who were initially managed with NOM and followed-up by protocolized CT were included. The primary outcome was the incidence of delayed PSA. Secondary outcome measures were delayed angiography and delayed splenectomy. Subgroup analyses were performed between NOM patients without initial splenic angioembolization (SAE) and NOM patients with initial SAE. RESULTS: Twelve studies were enrolled, including 11 retrospective studies and one prospective study, with 1746 patients in total. The follow-up CT rate in the included patients was 94.9%. The estimated incidence of PSA was 14% (95% confidence interval (CI), 8%-21%). The estimated delayed angiography and delayed splenectomy incidence rates were 7% (95% CI, 4%-12%) and 2% (95% CI, 1%-6%), respectively. Subgroup analyses showed that the estimated PSA incidence was 12% in NOM patients without initial SAE (95% CI, 7%-20%) and was also 12% in NOM patients with SAE (95% CI, 5%-24%). CONCLUSIONS: The estimated incidence of delayed PSA after follow-up CT for adult splenic injury with NOM was 14%. The estimated incidence of PSA in NOM with initial SAE was similar to that in NOM without initial SAE.

Pancreaticoduodenal Artery Pseudoaneurysm Associated with Pancreatic Fibroinflammatory Mass and Duodenal Obstruction.

BACKGROUND When people in their 60s experiences abdominal pain, vomiting, and unexplained weight loss without a history of abdominal surgery, the usual diagnosis is obstruction caused by a neoplastic mass. Nevertheless, in exceptionally rare cases, these symptoms arise from complications linked to a visceral artery aneurysm. CASE REPORT We present a case of a 60-year-old man with immunodeficiency and Sneddon-Wilkinson disease (a rare subcorneal pustular dermatosis), who developed a pancreaticoduodenal aneurysm of uncertain origin, associated with pancreatic mass, retroperitoneal hematoma, and duodenal obstruction. The treatment approach included transcatheter arterial coil embolization with supportive measures such as parenteral nutrition, a nasogastric tube, octreotide administration, and antiemetics. Despite these interventions, persistence gastrointestinal symptoms prompted an endoscopic ultrasound fine-needle aspiration to rule out malignancy. The biopsy confirmed localized fibro-inflammation. Although he was initially considered for a gastro-jejunal bypass, conservative management effectively improved the pancreatic lesion and duodenal obstruction, leading to discontinuation of parenteral nutrition. The patient was able to resume a regular diet 4 weeks after embolization. CONCLUSIONS Pancreaticoduodenal artery aneurysm is a rare visceral aneurysm with multiple etiologies and potentially fatal consequences. We report an unusual case of a pancreaticoduodenal artery aneurysm associated with pancreatic mass and duodenal obstruction. This diagnosis warrants consideration when an immunodeficient patient presents symptoms of abdominal pain and vomiting. Early endovascular embolization, combined with conservative approaches, effectively alleviated the symptoms in our patient.
