EMBOLIZATION FOR THE TREATMENT OF DELAYED HEMATURIA RENAL ARTERY PSEUDOANEURYSM FOLLOWING BLUNT TRAUMA

Background: The occurrence of a renal artery pseudoaneurysm after blunt renal trauma is an infrequent complication. The occurrence of delayed bleeding is typically observed within a period of 2 to 3 weeks following an injury and is commonly attributed to the presence of an arteriovenous malformation (AVM) or pseudoaneurysm. They are frequently observed in cases of injuries of greater severity or trauma that penetrates the body. The application of angiographic catheterization is efficacious in the detection of pseudoaneurysms in the renal artery. The management of renal pseudoaneurysms necessitates the consideration of distinct clinical associations, including the location and size of the lesion as well as the presence of symptoms.
 Objective: The objective of this study is to provide a detailed account of the use of an angiographic catheter and embolization in the treatment of a patient afflicted with a post-traumatic renal artery pseudoaneurysm.
 Materials and Methods: Conducting a literature review and medical records.
 Results: A case of renal artery pseudoaneurysm is presented. A male individual aged 33 sought medical attention at the emergency department following a motorcycle collision and exhibited symptoms of pain in the right flank region. The individual underwent a medical intervention involving the placement of a double J stent. After a period of nearly fourteen days, the individual reported experiencing hematuria. The abdominal CT scan revealed a renal injury on the right side with an AAST grade of 4, while the renal CTA demonstrated the presence of a pseudoaneurysm. A pseudoaneurysm was observed at the renal poles on the right side through the use of an angiographic catheter. The procedure of selective embolization utilising coils was executed on the renal arteries located at the lower and middle poles of the right kidney.
 Conclusion: The occurrence of renal artery pseudoaneurysms is infrequent; however, it is a grave complication that may arise from renal trauma. The accurate diagnosis and effective management of pseudoaneurysms are of paramount importance due to their potential to cause severe and potentially fatal complications if left untreated. The diagnostic process for pseudoaneurysms heavily relies on the involvement of the general radiologist. Interventional radiology provides alternative minimally invasive procedures that are linked to reduced morbidity and mortality rates and have replaced surgical interventions in the management of certain conditions.

Spontaneous Renal Artery Pseudoaneurysm Treated By Arterial Embolization

Renal artery pseudoaneurysm is a rare vascular lesion. It is found with increasing frequency as a result of unrelated abdominal imaging or on work-up for hypertension. The pseudoaneurysm can be defined as a pulsatile hematoma that communicates with the artery through a small hole in the arterial wall. However, the rupture of pseudoaneurysmis the most dreaded complication because it causes death. There are many causes of renal artery pseudoaneurysm and are generally related to renal biopsy, nephrectomy or percutaneous procedures. In addition, there is a relationship with penetrating traumas and, more rarely, with blunt traumas. We report a case of renal artery pseudoaneurysm treated successfully with vascular plug embolization. A 22-year-old woman with hypertension presented with an incidental left renal artery pseudoaneurysm measuring 35x23 mm. We successfully performed endovascular treatment with vascular plug embolization without any complications.

Successfully treated isolated renal artery pseudoaneurysm in a patient with Behçet's disease

Renal artery aneurysms and pseudoaneurysms are an uncommon clinical problem with a low incidence rate. They are abnormal dilatations of the vessel lumen with some different natures. However, the rupture of an aneurysm and pseudoaneurysm is the most dreaded complication because it causes death of the patient. There are many causes of renal artery aneurysm and pseudoaneurysm, including Behçet's disease; however, renal involvement in Behçet's disease is less frequent. We report a case of renal artery pseudoaneurysm induced by Behçet's disease and treated successfully with coil embolization. A 56-year-old woman with Behçet's disease presented with an incidental left renal artery pseudoaneurysm measuring 18 mm. We successfully performed endovascular treatment with coil embolization instead of surgical treatment.

Role of ultrasonography in detection of renal artery pseudoaneurysm caused by retroperitoneal malignant peripheral nerve sheath tumor in a patient with neurofibromatosis type 1.

Malignant peripheral nerve sheath tumors (MPNSTs) are extremely uncommon neoplasms, predominantly seen within the deep soft tissues of the extremities, in close proximity to the nerve trunks. Retroperitoneal MPNSTs are exceedingly rare, usually seen in association with neurofibromatosis type 1 (NF-1), and often result from malignant degeneration of a plexiform neurofibroma. These tumors are highly malignant and the prognosis is worsened if they occur in association with NF-1. Metastasis is not uncommon, but local invasion by these tumors is rarely reported. Renal artery pseudoaneurysms are mostly iatrogenic and rarely result from invasion by retroperitoneal neoplasms. Ultrasonography is a valuable tool in early diagnosis of these neoplasms and vascular complications, particularly in emergency cases requiring immediate operative intervention. To the best of our knowledge, no case of renal artery pseudoaneurysm caused by retroperitoneal MPNST has been reported to date. We present a case of a middle-aged female with Von Recklinghausen disease, complaining of sudden onset of severe abdominal pain, where ultrasound accurately diagnosed renal artery pseudoaneurysm caused by a large retroperitoneal MPNST, and who was later treated by radical excision of the tumor and nephrectomy.

Pseudoaneurysm After Laparoscopic Partial Nephrectomy for an 11-cm Renal Tumor

A case of renal artery pseudoaneurysm (RAP) after partial nephrectomy for an 11-cm renal tumor is reviewed. Symptoms, computed tomography (CT) scan images and angiography are all displayed. A 57-year-old woman was readmitted 4 months after she underwent a retroperitoneal laparoscopic partial nephrectomy for an 11-cm right renal tumor. Contrast CT revealed a 10.3-cm mass recurrence in the same position as her former tumor. Renal arteriography confirmed active bleeding from the anterior upper pole segmental branch into a 3 × 3 × 7-cm pseudoaneurysm. Percutaneous selective coil angioembolization was successfully performed. The remaining kidney parenchyma was fully preserved.

Percutaneous Embolization of Renal Artery Pseudoaneurysm after Laparoscopic Partial Nephrectomy for Renal Cell Carcinoma

Currently, partial nephrectomy for patients with malignant renal tumors has become the procedure of choice for elective indications. Attempts have been made to use minimally invasive endoscopic procedures to replace the standard open partial nephrectomy. Laparoscopic partial nephrectomy can be technically challenging and be associated with vascular complications such as pseudoaneurysm. We report here on a case of renal artery pseudoaneurysm that occurred after laproscopic partial nephrectomy for renal cell carcinoma treated by percutaneous selective angioembolization.

A delayed case of renal artery pseudoaneurysm presented with gross hematuria and azotemia in solitary kidney following percutaneous nephrostomy: treated by transcatheter coil embolization

Renal arteriovenous fistula or pseudoaneurysms developing after invasive procedures are either asymptomatic or show only transient symptoms. We describe here a case of symptomatic renal artery pseudoaneurysm that presented with gross hematuria and azotemia. The pseudoaneurysm of renal artery was diagnosed by ultrasonography and abdominal magnetic resonance imaging (MRI), and it was successfully treated by percutaneous transcatheter coil embolization. A high index of suspicion is essential for the early diagnosis and treatment of delayed gross hematuria in patients with history of percutaneous nephrostomy.

Pseudo-aneurisma arterial pós-transplante renal

Vascular complications after kidney transplantation have been described and pseudoaneurysms represent a well-recognized vascular complication. Although the incidence of pseudoaneurysm is low, it may potentially cause graft loss or may even be fatal for the patients if it is not diagnosed and treated quickly. The authors report a case of renal artery pseudoaneurysm diagnosed two months posttransplantation with cadaveric graft, the treatment and literature data.

Renal Artery Pseudoaneurysm Demonstrated on Radionuclide Scintiscan

The authors present a case of renal artery pseudoaneurysm demonstrated on the Tc-99m DTPA dynamic study. On the blood flow image, localized increased activity was noted in the are of the renal hilus. This activity disappeared on the subsequent sequential renal images.
