Percutaneous glue embolization as an alternative treatment for visceral pseudoaneurysms

Visceral artery pseudoaneurysm is a rare, life-threatening medical condition with a high incidence of rupture and bleeding. At most institutions, endovascular intervention is considered the first-line treatment with surgical repair as a secondary option. Percutaneous glue embolization is emerging as a safe alternative technique for minimally invasive treatment of visceral pseudoaneurysms. This case series aims to promote percutaneous glue embolization as a life-saving measure in cases where an endovascular approach cannot be performed successfully, and patients are not surgical candidates.

Mycotic Pseudoaneurysm of the Internal Mammary Artery: An Unusual Complication of Tuberculosis—Managed with Percutaneous Glue Embolization

AbstractTuberculosis is still an endemic in many parts of the world. Vascular complications have been described in patients with tuberculosis and in aggressive chest infections such as actinomycoses. Etiology of internal mammary artery pseudoaneurysms includes iatrogenic causes or a complication of infection (mycotic aneurysm). Early diagnosis and treatment of these aneurysms are key to prevent complications such as hemorrhage, hemothorax, and hemorrhagic shock. In this case report, we describe the presentation and management of a 11-year-old patient with tuberculosis, who developed an internal mammary artery pseudoaneurysm during the course of treatment. We describe the case of a 11-year-old girl with known tuberculosis who developed a left internal mammary artery pseudoaneurysm, and treated with percutaneous ultrasound-guided glue embolization.

Combined DSA- and US-guided management of acute bleeding: effectiveness of percutaneous glue embolization in six cases.

This study aims to report on safety and effectiveness of glue embolization of acute hemorrhages performed by US-guided percutaneous direct puncture, in patients where the standard endovascular approach is technically unfavourable. In this single center retrospective analysis, patients affected by traumatic or non traumatic acute hemorrhages were treated with glue embolization technically performed by US-guided direct puncture. Patients suffered from active bleeding detected at contrast-enhanced Computer Tomography and confirmed at Digital Subtracted Arteriography, with concomitant hemoglobin drop and blood pressure reduction. Six patients were reviewed; hemorrhages occurred in liver parenchima (1), gallbladder (1) and lower limbs (4). Bleedings etiologies were post-traumatic (5) and inflammatory (1); four had extraluminal blushes while 2 were pseudoaneurysms. In five cases (4 limbs and 1 hepatic bleedings) the direct-puncture approach was adopted because of technically unfavourable vascular anatomy for superselective embolization; in one case (cystic artery pseudoaneurysm), an endovascular embolization would entail a high risk of gallbladder ischemia because of its terminal arterial supply. Technical success was defined disappearance of bleeding signs at last arteriography; clinical success was considered stabilization and/or improvement of hemoglobin values and arterial pressure without additional interventions. Both technical and clinical successes were obtained in 100% of the cases without major complications. No needle occlusion occurred during glue injection. In this study percutaneous US-guided embolization by direct puncture was a safe and effective approach to manage acute bleedings; it could be considered as an alternative in patients with unfavourable vascular anatomy for the standard catheter-directed endovascular embolization.

Percutaneous Treatments for Persistent Bronchopleural and Alveolar-Pleural Fistulae

Percutaneous glue embolization was investigated as a treatment for bronchopleural fistulae (BPFs) and alveolar-pleural fistulae (APFs) associated with persistent air leak. Seven consecutive patients with persistent air leak were treated with percutaneous glue embolization of the BPF/APF from both iatrogenic and spontaneous causes. Treatment was performed using direct n-butyl cyanoacrylate (nBCA) glue injection for discrete, visible fistulae (n = 4), fibrin glue spray for suspected tiny multifocal leaks (n = 2), or both (n = 1). The number of treatments required per patient was 1 (n = 3), 2 (n = 3), or 3 (n = 1). Technical success was achieved in all cases. Follow-up showed resolution of all air leaks, with mean chest tube removal at 7.1 days after the embolization. The follow-up duration ranged from 2 to 47 months. No significant procedure-related morbidity, mortality, or recurrence was encountered. Percutaneous treatment for persistent BPFs and APFs showed good efficacy in this small case series and warrants further investigation.

Glue Embolization in the Management of Rectus Sheath Hematomas.

This study aims to describe the results achieved in the management of rectus sheath hematoma (RSH) using glue embolization. Data about all consecutive patients presenting with RSH, between January 2005 and December 2020 were retrospectively reviewed. RSHs were classified according to the Berna CT scan Classification. Clinical and technical outcomes were evaluated during in-hospital period and 1-month follow-up. Among 74 patients presenting with RSH, CTA revealed an active bleeding in 61 (n = 42, 69% women; median age = 68.8y range: 47-91). 19 cases of type 1 RSH (25.7%), under anticoagulation therapy and hemodynamically stable, were successfully managed conservatively. Conversely, endovascular embolization with cyanoacrylate glue diluted with ethiodized oil (Lipiodol Ultrafluid, Guerbet, France) was needed in n = 42 (56.8%) patients, in 16 cases after failure of conservative management; a single session of percutaneous glue embolization was adequate to achieve technical and clinical success in all patients with stabilization or progressive improvement of hemoglobin values after procedure (7.1 + 1.8g/dL pre-procedure vs 11.1 + 1.6g/dL post-procedure). No major complications occurred. Two minor complications were reported: 1 case (2.4%) of puncture site-related complication (local self-limiting hematoma) and 1 case (2.4%) of post-embolization syndrome (abdominal pain) spontaneously regressive. The median hospital stay was 7d. At 30-day follow-up, 2 patients (2.7%) died of multiorgan failure. In the management of RSH, glue embolization was shown to be safe and efficacious. Glue allowed the immediate occlusion of both the "front and back doors" of bleeding without the need to reach the bleeding point, preventing potentially life-threatening recurrence.

Percutaneous glue embolization as a primary treatment for visceral pseudoaneurysms

Aim: To evaluate the feasibility and outcome of percutaneous glue embolisation as primary treatment for pseudoaneurysms in selective patients.Material and methods: A review of the pseudoaneurysm cases managed with percutaneous glue at our institute was analyzed in this study. A total of 21 patients over a period of last one year who were treated for pseudoaneurysm at varied sites primarily with percutaneous n-butyl cynoacrylate were retrospectively evaluated. Site of pseudoaneurysm was Pulmonary (seven cases), renal (four cases), pelvic (4four cases) and miscellaneous abdomen (six cases). Combined ultrasound and fluoroscopy approach was used in 17 cases, CT guidance in three cases and combined ultrasound and CT guidance in one case. Patients were evaluated for therapeutic response (radiological and clinical) and procedure related complications.Results: Complete occlusion of the pseudoaneurysm was seen in all patients. Two patients showed mild pneumothorax and one patient showed reflux into the intercostal artery. All the patients showed symptomatic improvement and discharged in stable condition.Conclusions: Percutaneous glue embolisation of the pseudoaneurysms as a primary treatment is feasible and can be safely carried out in select group of patients with good therapeutic response and minimal complications

Efficacy and safety of ultrasound guided percutaneous glue embolization in iatrogenic haemorrhagic complications of paracentesis and thoracocentesis in cirrhotic patients.

To compare the safety and efficacy of ultrasound guided percutaneous glue (N-butyl-2-cyanoacrylate) embolization with transarterial embolization in the management of iatrogenically injured arteries while performing paracentesis or thoracocentesis in patients with chronic liver disease. Hospital database was searched for cirrhotic patients having abdominal/thoracic wall haemorrhage following paracentesis/thoracocentesis procedure from January 2011 to June 2016. Doppler ultrasound and/or CT angiography were used to localize the site of haemorrhage and patients were treated by transarterial embolization or ultrasound-guided percutaneous glue embolization. Technical success was defined as cessation of haemorrhage as evidenced by angiography/Doppler ultrasound and clinical success was evaluated in terms of stabilization of the vital signs without the need for further transfusion or pressors, and survival. In both groups, the time to "imaging diagnosis of haemorrhage" and "successful embolization" with the outcome was analysed. 23 cirrhotic patients had bleeding following a percutaneous procedure, 8 (Group 1) of them underwent transarterial embolization while 15 (Group 2) underwent ultrasound-guided percutaneous glue embolization. Mean time needed for embolization in Group 1 was 41 min while in Group 2 was 9 min (p < 0.001). Technical success was achieved in all but one case requiring repeat glue embolization. Initial clinical improvement was noted in all cases but the 30-day mortality owing to all causes was not significantly different between treatment groups. The study and its outcome suggest that ultrasound guided percutaneous glue embolization is a quick and effective treatment for iatrogenic haemorrhage following paracentesis/thoracocentesis in cirrhotic patients with comparable results to transarterial embolotherapy. Advances in knowledge: This study details an innovative technique of ultrasound guided percutaneous glue embolization of the iatrogenically injured vessel in the management of active extravasation and pseudoaneurysm developing after paracentesis/thoracocentesis in patients with cirrhosis.

Unconventional Management of Chyloascites After Laparoscopic Nissen Fundoplication

Chyloascites is a rare complication that can result from abdominal trauma, neoplasm, inflammatory conditions, or various abdominal surgeries. Few cases have been described secondary to iatrogenic injury from laparoscopic Nissen fundoplication. We describe a case in which this surgery resulted in chyloascites that was successfully treated by lymphatic glue embolization. A 37-year-old male presented with signs and symptoms consistent with chronic reflux disease. He underwent an uneventful laparoscopic Nissen fundoplication. Two weeks postoperatively, he was admitted for dehydration. During his admission, he began to develop a persistent cough, shortness of breath, and abdominal distention. Imaging and fluid analysis from thoracocentesis and paracentesis were consistent with chyle leakage. Despite nonoperative measures, the patient's presentation persisted. Thoracic duct ligation was performed without success. Bipedal lymphangiography identified an extensive leak revealing a severely lacerated thoracic duct spilling contrast freely into the abdomen and no contrast entering the thoracic duct in the chest. The site of injury was successfully sealed off with percutaneous glue embolization through lymph channels. Chyloascites is a rare complication of laparoscopic Nissen fundoplication. When not successful with conservative measures, lymphatic glue embolization can provide effective treatment.

Percutaneous Glue Embolization of a Visceral Artery Pseudoaneurysm in a Case of Sickle Cell Anemia

Although aneurysmal complications of sickle cell anemia have been described in the intracranial circulation, visceral artery pseudoaneurysms in this disease entity have not previously been reported in the literature. Conventional treatment of visceral pseudoaneurysms has been surgical ligation or resection of the aneurysm. Transcatheter embolization has emerged as an attractive, minimally invasive alternative to surgery in the treatment of these lesions. In certain situations, however, due to the unfavorable angiographic anatomy precluding safe transcatheter embolization, direct percutaneous glue injection of the pseudoaneurysm sac may be considered to achieve successful occlusion of the sac. The procedure may be rendered safer by simultaneous balloon protection of the parent artery. We describe this novel treatment modality in a case of inferior pancreaticoduodenal artery pseudoaneurysm in a patient with sickle cell anemia. Although a complication in the form of glue reflux into the parent vessel occurred that necessitated surgery, this treatment modality may be used in very selected cases (where conventional endovascular embolization techniques are not applicable) after careful selection of the balloon diameter and appropriate concentration of the glue-lipiodol mixture.
