“…Next, a fibrous reaction occurs that encapsulates the hemorrhage, forming a structure that resembles an aneurysmal sac. There is a theory that when this pseudoaneurysm bleeds, a hematoma is formed that is accompanied by a fibrous reaction, which if it persists is capable of eroding the intestinal wall, which until that moment served as containment, forming a fistulous path from the pseudoaneurysm toward the intestinal lumen 7 .…”

Arterioenteric fistulas (AEFs) are a rare disease. They are a communication between a major artery and digestive tract. We present a patient who, after suffering a gunshot wound to the abdomen, underwent an exploratory laparotomy with damage control surgery, who later presented with hematemesis and melena. Studies were performed where an aneursyma of the right renal artery and gastrointestinal bleeding due to primary arterioenteric fistula were evidenced, which is successfully treated by angioembolization. Endovascular therapy for the treatment of AEF is a useful resource in patients with the previous abdominal surgeries that could make their management more difficult.

“…AEFs are a rare condition and are classified into the primary and secondary according to their etiology 1,4,7 . The primary fistulas are caused by aneurysms, trauma, radiotherapy, and atherosclerotic disease, their incidence ranges between 0.04% and 0.07% at the time of performing an autopsy.…”

“…Renal arterial pseudoaneurysm is a haematoma contained by the surrounding structures outside the vessel wall. (1) The incidence is low, the overall incidence ranges between 0.01% and 1% (2). This increases to 2.5% when only patients with systemic hypertension are considered (3).…”

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.

Purpose: Our study examines the etiological profile, clinical and imaging features of renal artery pseudo aneurysms (RAPs), as well as the efficacy and need for the angioembolization of RAPs in a resource-constrained setting. Materials and Methods: A total of 36 patients with RAPs were included in our study. Initial diagnosis was made by Doppler Ultrasonography (USG) followed by CT renal angiography in all cases. DSA was performed in 28 patients, as eight patients showed spontaneous resolution by thrombosis on immediate pre-procedure Doppler study. Angioembolization with a microcoil was performed for 30 aneurysms in 28 patients. Technical success was confirmed at the end of the procedure by a renal angiogram. To assess clinical success, we followed up with patients (with clinical and Doppler USG) for a period of six months. Results: The most common cause of RAPs in our study was percutaneous nephrolithotomy (PCNL), seen in 21 patients (58.3%), followed by trauma (25%), and partial nephrectomy (11%). All patients presented to us were within 21 days of the etiological event of hematuria or flank pain. USG was able to detect the RAP in 22 cases (61%). CT renal angiography was diagnostic in all patients but failed to demonstrate two additional aneurysms in one patient. RAP size ≤ 4 mm and absence of brisk filling on CT renal angiography was associated with spontaneous resolution in eight patients, probably an indication of the beginning of spontaneous thrombosis. Angioembolization was done using microcoils and showed 100% technical and clinical success. Conclusion: PCNL is the most common etiological factor for RAPs in our setting. Such patients should have a Doppler USG done prior to discharge from the hospital. CT angiographic flow dynamics (delayed peak enhancement) may be helpful in the identification of RAPs with a high probability of subsequent spontaneous resolution. Angiography followed by embolization using microcoils is the most effective and safe treatment for RAPs with no significant loss of renal parenchyma, although cost remains a limiting factor in our setting.
