[en] Purpose: To correlate the pre-surgical findings in MRI with the surgical results in Muellerian malformations. Material and methods: 14 pediatric patients were studied by MRI. MRI findings were divided in 4 groups according to the classification of the American Fertility Society (modified by Rock). Patient's age ranged between 12-17 years. Results: In our series 4 patients were included in Group I, 4 cases in Group II, 4 in Group III and only 2 in Group IV. All patients underwent reconstructive surgery based on MRI findings. Conclusions: In our series MRI was a useful method for the pre-surgical evaluation of Muellerian malformations. (author)
[en] Persistent primitive hypoglossal artery (PPHA) represents the second most common carotid-vertebrobasilar anastomosis. The association of PPHA with intracranial aneurysms is not unusual. Treatment of aneurysms located on the PPHA itself is challenging due to the increased risk of ischemic complications secondary to the hypoglossal artery often being the sole contributor of flow to the posterior circulation. We report a case of a wide-neck aneurysm in a PPHA successfully treated using a stent-assisted coil embolization technique.
[en] We present a case of popliteal artery pseudo aneurysm as a complication of osteochondroma of the distal femur. The popliteal artery is the most frequently implicated in these pathologies. In our case the combination of MRA and MR allowed to achieve a correct diagnosis avoiding the use of invasive methods. (author)
[en] Ruptured abdominal aortic aneurysm is related with a 100% mortality rate if left untreated. Even with surgical intervention or endovascular repair, mortality is still extremely high. However, there are conditions in which neither open surgical aneurysm repair nor endovascular aneurysm repair can be considered a viable therapeutic option because of comorbidities or anatomic reasons. We report a case of successful endovascular treatment in a patient with ruptured abdominal aortic aneurysm by occluding the abdominal aneurysm using the Amplatzer Vascular Plug (AVP II).
[en] Endoleak is a frequent complication after endovascular repair of aortic rupture. We describe the case of a female patient with traumatic aortic injury, treated with endograft, who developed a type II endoleak through the left subclavian and vertebral arteries. Both arteries originated independently from the aortic arch, and were managed with coil embolization of each vessel. We also report our experience with treating the left vertebral artery by placing a microcatheter through the right vertebral one.
[en] Mycotic aneurysms are uncommon, especially those located in visceral arteries. We present a case of a patient with two visceral mycotic aneurysms due to bacterial endocarditis, one located in right upper pole renal artery and the second in the splenic artery. Both aneurysms were treated as endovascular embolization using microcoils. In the aneurysm located at the renal artery, the technique of stent-assisted coils embolization was preferred to avoid coils migration due to its wide neck. The stent used was the Solitaire AB, which was designed for the treatment of intracranial aneurysms and was used recently in acute stroke as a mechanical thrombectomy device. Complete embolization of the aneurysm was achieved, preserving all the arterial branches without nephrogram defects in the final angiogram.
[en] The aim of this study was to evaluate the effectiveness of endovascular repair in the treatment of isolated iliac artery aneurysm (IAA) using Excluder bifurcated endograft. Eight consecutive patients with IAA were treated during a period of 45 months using Excluder bifurcated endograft. Two patients presented with isolated IAA rupture and were treated emergently, whereas the other six patients underwent elective treatment. All aneurysms lacked sufficient proximal necks and therefore were not suitable for tubular-shaped endograft. Follow-up imaging was performed at 1 week, at every 3 months during the first year, semiannually until 2 years, and annually afterward using angio-computed axial tomography and plain films. Technical success was achieved in all patients. No mortality was seen despite two patients having IAA rupture. Follow-up (12 to 60 months) was done in all but one patient. During this period, complications were observed in three patients. One patient developed sexual impotence at 3-month follow up; one patient presented unilateral gluteal claudication after the procedure, which resolved at 3 months; and one patient developed a graft porosity-related endoleak, which was successfully managed with placement of an additional ipsilateral iliac extension. Endovascular treatment of isolated IAA using bifurcated endograft is safe and can be an alternative to surgical treatment. The benefits from decreased morbidity and mortality of endoluminal treatment of isolated IAA using bifurcated endograft outweigh the minor complications associated with this technique, which are mostly related to occlusion of hypogastric arteries.
