Management of massive hemothorax due to internal mammary pseudoaneurysm treated with angioembolization post-cesarean section involving traumatic fetal extraction: A case report.

Introduction: Pseudoaneurysm, or false aneurysm, is a clinical entity caused by rupture of the arterial wall, leading to blood leakage that is confined by sorroundig tissue. Massive hemothorax constitutes a life-threatening condition demanding timely and accurate medical response. Case report: A puerperal presented with a massive hemothorax precipitated by a traumatic cesarean section due to hemorrhage from a pseudoaneurysm of the left internal thoracic artery. Initial treatment involved a sternotomy, followed by a conclusive therapy via angioembolization. Conclusion: Precise assessment, including the measurement and localization of the ITA pseudoaneurysm is crucial to formulate an appropriate therapeutic strategy. Current medial practice favors endovascular embolization as a reliable and minimally invasive alternative to open surgery, establishing ir as the treatment of choice.

Huge Pseudoaneurysm at the Aortic Bifurcation Misdiagnosed as a Mesenchymal Tumor: A Case Report.

Aortic pseudoaneurysms (PA) vary in size and may remain asymptomatic. PAs may be caused by vascular injury, such as trauma or surgery, or other non-traumatic causes, such as Bechet disease, infection, or penetrating atherosclerotic ulcers. The diagnosis of PAs may have been delayed for decades. We present a case of a PA detected incidentally in a male patient who experienced traumatic bowel perforation due to blunt abdominal trauma 30 years before presentation. Computed tomography (CT) displayed a 9.2 cm mass in the pelvis, initially considered a neoplasm of small bowel origin. Further analysis of the CT images suggested a thrombosed PA at the aortic bifurcation, which was confirmed via surgical exploration. Graft interposition was performed using a Dacron 16-8 mm graft and the patient recovered without any complications. This case highlights the importance of a high index of suspicion for the diagnosis of a thrombosed aortic PA.

False aneurysms of the thoracic aorta: anastomosis investigation using the inflation-extension test.

INTRODUCTION: False aneurysms in the thoracic aorta are dangerous complications that can occur after cardiac surgery. They often result in high mortality rates. These aneurysms are caused by damage to all layers of the aortic wall. This study aimed to pinpoint the area of the experimental specimen (native vessel, anastomosis, or prosthetic graft) with the greatest deformation, to determine whether a false aneurysm is likely to develop in the anastomotic portion. METHODS: We conducted the inflation-extension test by performing eight cycles ranging from 0 to 20. The pressure sampling frequency was 100 Hz, and each cycle lasted approximately 34 seconds, resulting in a loading frequency of 0.03 Hz. During the experiment, each camera captured 3,000 frames. Based on the data collected, we evaluated and compared the loading stages of cycle 1 and cycle 8. RESULTS AND DISCUSSION: During loading, the native vessel experienced a dominant deformation of approximately 7% in the circumferential direction. The prosthetic graft, which had a longitudinal construction, deformed by approximately 8% in the axial direction. The prosthetic graft, on the other hand, only experienced a deformation of up to 1.5% in the circumferential direction, which was about 5 times smaller than the deformation of the native vessel. The anastomosis area was very stiff and showed minimal deformation. Additionally, there was little difference in the mechanical response between the first C1 and the eighth C8 cycle. CONCLUSION: Based on the available evidence, it can be inferred that aortic false aneurysms are more likely to form just behind the suture lines in the native aorta, which is more elastic compared to stiff sections of anastomosis and prosthetic graft. Numerous pulsations of the native vessel will likely cause the impairment of the aorta at the margin of the anastomosis. This will lead to disruption of the aortic wall and false aneurysm formation in the native vessel near the area of anastomosis.

Mixed lesion of traumatic pseudoaneurysm and pyogenic granuloma on a digit.

Traumatic aneurysms occurring in the digit are extremely rare. We report a case of a traumatic pseudoaneurysm arising from a terminal branch of the finger artery and presenting as a mixed lesion with pyogenic granuloma that was exposed to the outside of the body and treated surgically.

Double Pseudoaneurysm of the Superficial Palmar Arch: A Unique Case.

We present the case of a 22-year-old male patient who developed "double" pseudoaneurysm of the superficial palmar arch of the left hand after trivial trauma with a kitchen knife. Following an unsuccessful embolization attempt, surgical excision of the pseudoaneurysm was performed during which the pseudoaneurysm was found to arise from the anterior wall of the palmar arch. Intraoperatively, a second pseudoaneurysm arising from the deeper surface of the superficial palmar arch was found and excised. This is probably the only reported case of double pseudoaneurysm of the palmar arch in literature. The possible mechanism of arterial injury, diagnosis, and management is discussed.

Delayed Presentation of Sciatic Nerve Palsy Due to Post-traumatic Pseudoaneurysm Following Pelvis Fracture: A Case Report.

Introduction: Pseudoaneurysms are vascular lesions occurring after injury to a blood vessel wall. Peripheral artery pseudoaneurysms as a fracture complication are uncommon and typically appear immediately after trauma or surgery. We report a unique case of sciatic nerve palsy associated with external iliac artery pseudoaneurysm arising 20 years after pelvic trauma, presenting within the fracture site as an erosive bone lesion masquerading as a possible malignancy. To the best of our knowledge, no cases of delayed external iliac artery pseudoaneurysm involving sciatic pain have been reported. Case Report: We present a 78-year-old female who sustained an acetabular fracture with an uneventful recovery for 20 years. The patient presented post-injury with symptoms and physical examination findings consistent with sciatic nerve palsy. Computed tomography angiography and duplex imaging revealed a pseudoaneurysm of the external iliac artery. The patient was taken to the operating room for endovascular repair of the external iliac artery using a covered stent. Conclusion: This case of sciatic nerve palsy is a unique contribution to the literature concerning the specific vascular injury observed and the delayed presentation of pseudoaneurysm causing sciatic nerve palsy. Orthopedic surgeons must consider a wide differential when confronted with suspicious pelvic masses. Failure to diagnose these as a vascular etiology could prove catastrophic should the surgeon attempt an open debridement or sampling.

Transcatheter closure of postsurgical aortic pseudoaneurysms guided by three-dimensional image reconstruction: a single-centre experience.

BACKGROUND: Postsurgical thoracic aortic pseudoaneurysms (PTAPs) are a potentially lethal complication after cardiac or aortic surgery. Surgical management can pose a challenge with high in-hospital mortality rates. Transcatheter closure is a less-invasive alternative treatment option for selected patients, although current experience is limited. AIMS: We aimed to evaluate procedural and imaging outcomes of our first 11 cases of transcatheter PTAP closure with the use of closure devices. METHODS: Patients with a high operative risk who underwent transcatheter PTAP closure at our centre from 2019 to 2021 were retrospectively included. Suitability was evaluated on preprocedural computed tomography (CT) scans and three-dimensional (3D) reconstructions. All procedures were performed in the catheterisation laboratory. Intraprocedural aortography and postprocedural CT scans with 3D reconstructions were used to evaluate PTAP occlusion. RESULTS: Eleven consecutive patients with a high operative risk and a history of cardiac/aortic surgery who underwent transcatheter PTAP closure were included. PTAPs were predominantly located at the proximal or distal anastomosis of a supracoronary ascending aortic vascular graft or Bentall prosthesis (82%). Implanted closure devices included Amplatzer Valvular Plug III (82%), Amplatzer septal occluder (9%) and Occlutech atrial septal defect occluder (9%). No periprocedural complications occurred. After device deployment, residual flow was absent on aortography in 64% and minimal residual flow was present in 36% of patients. Subtotal or total occlusion of the PTAP on follow-up CT ranged between 45% and 73%. CONCLUSIONS: Although subtotal or total occlusion of the PTAP was found at follow-up in only 45-73% of cases, transcatheter PTAP closure guided by preprocedural 3D reconstructions can offer a valuable minimally invasive primary treatment option for patients who otherwise would face a high-risk reoperation.

Infected False Aneurysm of Brachiocephalic Trunk - Rare but Highly Lethal Cause of Dyspnea.

False aneurysm of the brachiocephalic trunk is a very rare but highly lethal, life-threatening, and difficult-to-treat condition. In this report, we present a case of a patient who suffered from rapidly worsening dyspnea caused by infected false aneurysm of the brachiocephalic trunk compressing the trachea that was successfully treated by stent graft implantation. The main purpose of this article is to consider other, less common causes of dyspnea and to explain the pathogenesis of infected true/false aneurysm and its management. Due to the rarity, history-taking and physical examination should be thorough, and symptoms and signs should be analyzed deeply. Simplification should be avoided during diagnosis. In addition, we would like to highlight the option of stent grafts as an alternative to surgery in the management of patients suffering from infected aneurysm who are at high surgical risk.

[Complicated visceral artery aneurysms in chronic pancreatitis]. / Oslozhnennye anevrizmy vistseral'nykh arterii pri khronicheskom pankreatite.

Visceral artery aneurysms are rare and occur only in 0.01-0.2% of people. According to various authors, incidence of aneurysm rupture is 10-20% with mortality rate of 20-70% depending on localization and dimensions. One of the causes of visceral artery aneurysms, in particular common hepatic artery aneurysm, is chronic pancreatitis. Incidence of this complication is 2-10%. The first clinical manifestation is often hemorrhagic shock following false aneurysm rupture and bleeding into abdominal cavity, gastrointestinal tract or retroperitoneal space. Common hepatic artery aneurysm is complicated by bleeding in 35% of cases, and mortality may be up to 75%. Treatment of visceral artery aneurysm following chronic pancreatitis and post-necrotic parapancreatic cyst includes several stages. Endovascular methods are the first stage of treatment. The second stage is elimination of the cause of visceral artery false aneurysm (surgery for chronic pancreatitis). We present 3 patients with visceral artery aneurysms and chronic pancreatitis.

Endovascular repair of ruptured external iliac artery pseudoaneurysm and arteriovenous fistula using reversed bell-bottom technique.

Pseudoaneurysm and arteriovenous fistula can occur after iatrogenic trauma or penetrating injuries. Endovascular treatment is a minimally invasive method used to manage these complex vascular injuries. We have described the case of a 27-year-old male patient who had presented with progressively increasing pain and swelling of the left inguinal region after a gunshot injury 5 years earlier. The bell-bottom technique was used in a reversed fashion to exclude the pseudoaneurysm and treat the arteriovenous fistula, achieving symptom resolution without complications.

Presentation of a large pseudoaneurysm of the brachial artery: A case report.

Brachial artery pseudoaneurysms (PSA) are considered uncommon, but they can be limb and life threatening. Most etiologies are related to iatrogenic injury or following a fracture. Here we present a 37-year-old male complaining of a large swelling in his right upper arm that was gradually increasing in size for the last 7 months. It started with a sudden onset of pain while lifting heavy boxes at his daily job. Ultrasound and MRA showed a pseudoaneurysm of the right brachial artery. Resection of the PSA was performed with a vein interposition graft. This case illustrates the significance of considering PSA as a differential diagnosis in patients presenting with upper arm swelling without history of obvious trauma.

Incidental pseudoaneurysm of the mitral-aortic intervalvular fibrosa in asymptomatic patient: A case report.

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) can be a rare but life-threatening complication of infective endocarditis, cardiac surgery, or blunt chest trauma. Congenital heart diseases especially in young patients are reported as additionally predisposing factors. We present the case of an asymptomatic 52 years-old male with bicuspid aortic valve and gastrointestinal polyposis syndrome in whom a P-MAIVF was incidentally detected. The patient successfully underwent pseudoaneurysm surgical repair and aortic valve replacement and despite no evident causes were found we hypothesized addiotional underlying mechanism of P-MAIVF.

Left Ventricular Pseudoaneurysms Discovered Early After Acute Myocardial Infarction: The Surgical Timing Dilemma.

Left ventricular pseudoaneurysm is a rare disease; it is defined as a ventricular rupture contained by epicardium, pericardial adhesions, or both. It most frequently occurs as a complication of acute myocardial infarction. Surgical treatment is recommended for pseudoaneurysms that are large or symptomatic and for those discovered less than 3 months after myocardial infarction. We report our experience with 2 patients who had left ventricular pseudoaneurysms discovered less than a week after inferior myocardial infarction. Both patients were middle-aged men with right coronary occlusion in whom the diagnoses were established by echocardiography during the first week after infarction. Because both patients were clinically stable, we opted to defer surgery until scarring could facilitate correction; this decision was based on a review of the literature showing that in-hospital mortality is higher with early surgery. The patients were monitored closely in the intensive care unit and were prescribed ß-blockers and vasodilators. Both patients underwent left ventricular patch reconstruction with exclusion of the pseudoaneurysm and posterior septum; both received moderate inotropic support and prophylactic intra-aortic balloon pump assistance. Their postoperative courses were uneventful. In 5 prior reports describing 45 patients (13 with acute pseudoaneurysm [≤2 wk after infarction] and 32 with nonacute pseudoaneurysm), in-hospital mortality was 61.5% for patients in the acute group and 15.6% for the nonacute group (P = .0066). We recommend that clinicians consider deferring surgery for patients with stable acute left ventricular pseudoaneurysm to reduce the risks associated with early repair.

Treating Femoral Artery Pseudoaneurysm by Tumescence Anesthesia and Echo-Guided Compression Technique (TACT): Clinical Outcome in 82 Consecutive Patients.

PURPOSE: Pseudoaneurysm (PA) of the access artery is a common and potentially severe complication after percutaneous endovascular interventions. Most PA require interventional therapy, including thrombin injection, covered stent implantation, or surgical repair, which are costly and associated with other complications. Treating PA by external compression is uncomfortable and time consuming, with a low success rate. By injecting local tumescence anesthesia around the PA and close to its neck, the tumescence anesthesia and echo-guided compression technique (TACT) aims to improve efficacy and patient's comfort. MATERIALS AND METHODS: We retrospectively reviewed all consecutive patients treated for femoral PA in our center from May 2009 to July 2019 and estimated efficacy and safety. Vascular specialists performed TACT according to a standardized protocol including ultrasound-guided injection of tumescence solution (45 ml of 0.9% saline, 15 ml of lidocaine 1%/epinephrine 5 µg/ml) in the soft tissue around the PA and its neck, local compression with the sonography probe until PA closure, and external compression by elastic belt for 3 hours. RESULTS: Among a total of 125 patients with femoral artery PA, 82 (65.6%) were treated by TACT (including 3 patients with haemorrhagic shock), 14 (11.2%) by thrombin injection; 12 (9.6%) by endovascular interventions; 8 (6.4%) by open surgery; and 9 (7.2%) conservatively. In patients treated by TACT, PA neck was short (<1 cm) in 51.8% and mean cavity diameter 30 ± 23 mm. After injection of 58 ± 8 ml of tumescence solution, mean time of echo-guided compression was 12 ± 8 minutes. Pseudoaneurysm was successfully closed in 92.7% after the first attempt and in 96.3% after the second attempt. The intervention was well tolerated, without any adverse event. CONCLUSION: Tumescence anesthesia and echo-guided compression technique (TACT) is an effective and safe treatment for PA. Compared to other therapies, TACT is minimally invasive and widely available for minimal costs, even for large PA and in unstable patients. CLINICAL IMPACT: Tumescence anesthesia and echo-guided compression technique seems to be an efficient, safe, and a fair economical choice in comparison with alternative techniques. The implementation of this procedure is simple with low risk of complications. Based on the results of this study, we believe that TACT should be considered as the first-line treatment of most iatrogenic PA.

Treatment of pulmonary artery pseudoaneurysms and stenosis with balloon-expandable stents.

We describe our use of balloon-expandable stents in pulmonary arteries for a variety of indications. This is an endovascular technique that provides an alternative treatment option to treat some forms of complex pulmonary artery disease when standard surgical or other endovascular options are not possible. This case series describes the successful treatment of four patients with different pulmonary artery diseases. Indications for stent placement include multiple broad-necked pulmonary artery pseudoaneurysms, symptomatic malignant pulmonary artery narrowing and post-surgical iatrogenic pulmonary artery stenosis. No stent-related complication had been identified from 3 months to 4 years of follow-up. All surviving patients have experienced sustained symptomatic improvement.

Infectious Pulmonary Artery Pseudoaneurysm That Resolved with Conservative Treatment.

Pulmonary artery pseudoaneurysms (PAPs) are rare but can cause massive hemoptysis if they rupture. Infectious PAPs are often treated by surgery or transcatheter embolization and are rarely treated conservatively with antibiotics. We herein report a case of PAP treated conservatively in a 21-year-old woman with lung abscess. Except for one massive hemoptysis early in the course, the patient responded well to the empirical therapy with ampicillin/sulbactam and systemic hemostatic agents. After six weeks of antibiotics, the pseudoaneurysm disappeared. Conservative therapy with careful observation can be considered in small infectious PAPs when there is a good clinical response to initial conservative therapy.

Necessity of life-long follow-up after surgery for coarctation of the aorta: a case series of very late false aneurysm formation.

BACKGROUND: Coarctation of the aorta accounts for 5-7% of congenital defects of the heart and great vessels. It requires treatment in the form of open surgical or percutaneous repair. Common long-term complications include re-stenosis and aneurysm formation. The formation of a false aneurysm is a complication with a significant morbidity and mortality. CASE SUMMARY: We reviewed six cases of late false aneurysm after repair of a coarctation of the aorta. Our six cases developed a false aneurysm after an open surgical repair of a coarctation more than 30 years after initial surgical repair. All aneurysms were located at the aortic repair site. DISCUSSION: The symptoms or risk factors in the described cases are not uniform and are difficult to include in a general follow-up protocol. Guidelines recommend frequent evaluation, but do not specify duration or intervals of imaging follow-up. Our cases support the necessity of life-long follow-up in patients with open aortic repairs irrespective of symptomatology.

Manejo anestésico durante la cirugía para pseudoaneurisma ventricular izquierdo / Anesthetic management during surgery for left ventricular pseudoaneurysm

Resumen: Se informa la conducta anestésica de un caso de pseudoaneurisma ventricular izquierdo crónico secundario a complicación de infarto de miocardio transmural, complicación rara y casi siempre mortal. En este informe se describe el caso de una mujer de 60 años con insuficiencia cardíaca aguda a consecuencia de un infarto cardíaco ocurrido cinco meses atrás, que generó la complicación de la cual damos referencia. El manejo anestésico perioperatorio se logró al enfocarse en mantener una presión arterial estable para garantizar la perfusión cerebral y reducir el riesgo de ruptura completa del aneurisma hacia el espacio mediastinal.

Abstract: The anesthetic behavior of a case of chronic left ventricular pseudoaneurysm secondary to a complication of transmural myocardial infarction, a rare and almost always fatal complication, is reported. This report describes the case of a 60-year-old woman with acute heart failure, this is a consequence of a heart attack that occurred 5 months ago, which generated the complication of which we refer. Perioperative anesthetic management was achieved by focusing on maintaining a stable blood pressure to ensure cerebral perfusion and reduce the risk of complete rupture of the aneurysm into the mediastinal space.

Surgical and Conservative Treatment of Post-infarction Left Ventricular Pseudoaneurysm.

BACKGROUND: Post-infarction left ventricular (LV) pseudoaneurysm is a rare mechanical complication of myocardial infarction that carries a substantial risk of sudden rupture. The purpose of this study was to compare the surgical results of post-infarction LV pseudoaneurysm with those of conservative treatment. METHODS: From 2016 to 2021, 22 patients were hospitalized for LV pseudoaneurysm, including 17 cases (77.3%) caused by myocardial infarction. Of the 17 patients, 10 (58.8%) underwent surgical repair, while seven (41.2%) were treated medically. The clinical course, echocardiograph data, and surgical outcomes were analyzed. Survival rates of the surgical and conservative groups were compared. RESULTS: There were no perioperative deaths. Intra-aortic balloon pumping support was required in two (20%) patients. No follow-up mortality was observed in the surgical group and at the last follow-up, all the patients were classified as New York Heart Association class I-II. In the conservative group, there was one (14.3%) hospital death and two (28.6%) additional deaths during follow-up. A significant difference was found in survival between the two groups (P = 0.024). CONCLUSIONS: Surgical repair of post-infarction LV pseudoaneurysm can be performed with good results, while conservative treatment carries a significant risk of sudden death. Surgical repair is indicated for every patient diagnosed, even those with a small pseudoaneurysm without symptoms.
