Saccular intracranial neonatal aneurysm.

INTRODUCTION: Neonatal cerebral aneurysms are very rare condition and distinct from those of the adults. CASE REPORT: We reported a 14-day-old male neonate who presented subarachnoid hemorrhage due to a ruptured anterior cerebral artery saccular aneurysm. In addition, we present a review of the relevant literature. CONCLUSION: Intracranial hemorrhage due to cerebral aneurysm rupture in a newborn is an uncommon diagnosis, but it must be unequivocally excluded.

Ruptured renal artery aneurysm in a pregnant woman: case report and literature review / Ruptura de aneurisma de artéria renal em gestante: relato de caso e revisão da literatura

Abstract Renal artery aneurysms (RAAs) are rare and usually asymptomatic; ~ 90% of them are unilateral. Once diagnosed during pregnancy, they may rupture, presenting a high maternal-fetal risk. The present study reports the case of a 32-year-old pregnant woman with a 30-week gestational age and a ruptured unilateral RAA.

Transoceanic Management and Treatment of Aneurysmal Subarachnoid Hemorrhage: A 10-Year Experience.

BACKGROUND AND PURPOSE: Because of the small number of yearly cases of ruptured cerebral aneurysms, endovascular treatment is not performed in Martinique. Therefore, patients from Martinique are sent 7000 km to Paris on commercial flights as soon as possible, where treatment is performed. Nontransportable patients are treated locally with either surgery or symptomatic care. The objective of our study was to assess patient outcomes and safety of this treatment strategy. METHODS: We retrospectively examined all cases of aneurysmal subarachnoid hemorrhage in Martinique diagnosed during 2004 to 2013. Medical case records were searched for the type and location of treatment, clinical status, and transfer duration. RESULTS: A total of 119 patients had an aneurysmal subarachnoid hemorrhage during the 10-year period. Of these, 91 were transferred to Paris, 12 were surgically treated locally, and 16 received symptomatic treatment. None of the transferred patients experienced any hemorrhagic recurrence, and none suffered a significant complication related to the air transportation. The median time between aneurysmal subarachnoid hemorrhage diagnosis and arrival at the referral center was 32 hours. The 30-day case fatality rate for treated cases was 14.6% (8.8% for those treated in Paris and 58.3% for those treated locally). CONCLUSIONS: Our treatment strategy for aneurysmal subarachnoid hemorrhage resulted in a 30-day case fatality rate similar to those observed elsewhere, despite an 8-hour flight and a median treatment delay of 32 hours. This strategy therefore seems to be safe and reliable for isolated regions with small populations.

[Hughes-Stovin Syndrome, a case report]. / Síndrome de Hughes-Stovin.

The Hughes-Stovin syndrome is a rare entity characterized by deep vein thrombosis and pulmonary artery aneurysms of unknown etiology and pathogenesis. Some authors considered a variant of Behcet's disease. Its natural course is usually fatal. The symptoms are cough, dyspnea, hemoptysis, chest pain and fever. The treatment goes from steroids and cytotoxic agents to surgery. We present the case of a 41 year old man who shows dyspnea, hemoptysis, and chest pain leading to the diagnosis of deep venous thrombosis of the right leg, lung thromboembolism and pulmonary artery aneurysms. He was treated with high-dose corticosteroids and 6 cyclophosphamide pulses of 1 gram each per 6 months with complete regression of aneurysms and symptomatology.

Contemporary outcomes of intact and ruptured visceral artery aneurysms.

OBJECTIVE: The treatment outcomes of ruptured visceral artery aneurysms (rVAAs) have been sparsely characterized, with no clear comparison between different treatment modalities. The purpose of this paper was to review the perioperative and long-term outcomes of open and endovascular interventions for intact visceral artery aneurysms (iVAAs) and rVAAs. METHODS: This was a retrospective review of all treated VAAs at one institution from 2003 to 2013. Patient demographics, aneurysm characteristics, management, and subsequent outcomes (technical success, mortality, reintervention) and complications were recorded. RESULTS: The study identified 261 patients; 181 patients were repaired (77 ruptured, 104 intact). Pseudoaneurysms were more common in rVAAs (81.8% vs 35.3% for iVAAs; P < .001). The rVAAs were smaller than the iVAAs (20.7 mm vs 27.5 mm; P = .018), and their most common presentation was abdominal pain; 29.7% were hemodynamically unstable. Endovascular intervention was the initial treatment modality for 67.4% (75.3% for rVAAs, 61.5% for iVAAs). The perioperative complication rate was higher for rVAAs (13.7% vs 1% for iVAAs; P = .003), as was mortality at 30 days (13% vs 0% for iVAAs; P = .001), 1 year (32.5% for rVAAs vs 4.1% for iVAAs; P < .001), and 3 years (36.4% for rVAAs vs 8.3% for iVAAs; P < .001). Lower 30-day mortality was noted with endovascular repair for rVAAs (7.4% vs 28.6% open; P = .025). Predictors of mortality for rVAAs included age (odds ratio, 1.04; P = .002), whereas endovascular repair was protective (odds ratio, 0.43; P = .037). Mean follow-up was 26.2 months, and Kaplan-Meier estimates of survival were higher for iVAAs at 3 years (88% vs 62% for rVAAs; P = .045). The 30-day reintervention rate was higher for rVAAs (7.7% vs 19.5% for iVAAs; P = .019) but was similar between open and endovascular repair (8.2% vs 15%; P = NS). CONCLUSIONS: rVAAs have significant mortality. Open and endovascular interventions are equally durable for elective repair of VAAs, but endovascular interventions for rVAAs result in lower morbidity and mortality. Aggressive treatment of pseudoaneurysms is electively recommended at diagnosis regardless of size.

Ruptured true superficial femoral artery aneurysm / Aneurisma verdadeiro roto de arteria femoral superficial

Femoral artery aneurysms are rare and generally affect elderly patients. They are often diagnosed in combination with aneurysms in other locations, such as peripheral and aortic aneurysms. This case report describes a young patient whose superficial femoral artery (SFA) had a clinical presentation suggestive of a ruptured aneurysm. The patient underwent standard treatment, with aneurysmectomy and interposition of the ipsilateral saphenous vein. A review of the literature confirms the rarity of this case.

Os aneurismas de artéria femoral são raros e ocorrem geralmente em pacientes idosos. Estão frequentemente associados a outros aneurismas, tanto periféricos como de aorta abdominal. O presente relato refere-se a um jovem portador de aneurisma de artéria femoral superficial (AFS), cuja apresentação clínica foi a ruptura. O paciente foi submetido ao tratamento convencional, com ressecção do aneurisma e interposição de veia safena magna ipsilateral. A revisão da literatura corrobora a raridade do caso.

Endovascular treatment for acute aortic syndrome.

BACKGROUND: The term "acute aortic syndrome" (AAS) includes conditions of high mortality, such as ruptured aneurysm, pseudoaneurysm and, aortic dissection. Open surgery for these cases has demonstrated unsatisfactory results, and endovascular treatment has become an excellent alternative. METHODS: We performed a retrospective review of patients with AAS who underwent endovascular treatment in our emergency department from July 2009 to February 2011. They represent 64% (16 of 25) of all patients with AAS seen during this period. RESULTS: Sixteen patients underwent endovascular treatment: eight ruptured aneurysms, six aortic dissections, one nonruptured painful aneurysm, and one pseudoaneurysm. No intramural hematoma or penetrating atherosclerotic ulcer was found. The mean age was 64.3 years, and arterial hypertension (100%) and smoking (64.7%) were the major comorbidities. Technical success rate was 93%, and overall 30-day mortality was 6.25%. CONCLUSION: Endovascular treatment for AAS was feasible. Technical success, 30-day mortality, hospital stay, and procedure time were similar to those of the other series reported in the literature, and the endovascular approach has became the main technique for AAS in our hospital.

Terson's syndrome as a prognostic factor for mortality of spontaneous subarachnoid haemorrhage.

PURPOSE: To evaluate the prognosis of mortality in patients with spontaneous subarachnoid haemorrhage associated with Terson's syndrome. METHODS: A prospective, consecutive case series study was conducted in patients admitted to the emergency room with a diagnosis of acute subarachnoid haemorrhage. After a complete neurological examination, funduscopic examination using binocular indirect ophthalmoscopy under mydriasis was performed upon admission and at days 3, 7, 30 and 60 after the onset. In all cases, the diagnosis of intracranial bleeding was made by computerized tomography, and the clinical condition was graded according to the Hunt & Hess and Glasgow coma scales. RESULTS: Forty-seven patients with the diagnosis of subarachnoid haemorrhage were enrolled. Forty-four cases were associated with a ruptured aneurysm and three cases with arterio-venous malformation. Fourteen patients (29%) were diagnosed with Terson's syndrome. Seven patients (50%) with Terson's syndrome died, whereas death occurred in three patients (9%) without Terson's syndrome (p = 0.002). Ocular findings in Terson's syndrome were preretinal, intraretinal, sub-retinal and vitreous haemorrhage. Associated ocular findings included third-nerve palsy, papilloedema and subconjunctival haemorrhage. CONCLUSION: The presence of Terson's syndrome was associated with an increased mortality rate (50% versus 9%; p < 0.01). Therefore, patients with the diagnosis of intracranial haemorrhage should be submitted to a funduscopic examination, because the presence of intraocular haemorrhage is an important life-threatening prognostic factor.

Pseudoaneurysm of the gastroduodenal artery secondary to chronic pancreatitis.

Although pseudoaneurysms are a rare complication of chronic pancreatitis, they are potentially serious both because of the events they can lead to and the diagnostic challenges they may pose. Historically, they used to be treated surgically, through ligation and/or resection; it was not until the last decade that scarcely invasive percutaneous endovascular procedures were introduced. This article reports the case of a patient with chronic pancreatitis presenting with severe upper digestive hemorrhage caused by the rupture of a pseudoaneurysm of the gastroduodenal artery. The patient was successfully treated using selective embolization.

Involvement of the oral cavity in a carotid pseudoaneurysm of an adolescent treated by an endovascular procedure.

Pseudoaneurysms of the internal carotid artery are uncommon and normally secondary to trauma of the cervical region. Frequently it is the throat and neck doctor who evaluates these patients. We report on the case of a 15-year-old patient with active bleeding via the oral cavity, headache, and later hematoma in the cervical region. Arteriography demonstrated a pseudoaneurysm of the internal carotid artery. Angiography demonstrated successful embolization after the placement of coils and thus endovascular procedures are an alternative treatment for pseudoaneurysms of the internal carotid arteries in adolescents.

Aneurisma ilíaco associado a fístula arteriovenosa / Iliac aneurysm associated with arteriovenous fistula / Iliac aneurysm associated with arteriovenous fistula

A ruptura dos aneurismas aorto-ilíacos para a veia ilíaca ou veia cava é uma complicação pouco comum. A hipertensão venosa leva a vários sinais e sintomas, o que dificulta o diagnóstico pré-operatório, tais como edema do membro inferior, dispnéia, hematúria, sinais de insuficiência renal ou cardíaca. Sopro abdominal é a chave do diagnóstico clínico, associado à massa pulsátil e dor abdominal. O reconhecimento da fístula arteriovenosa no pré-operatório é importante para o planejamento cirúrgico. Relatamos um caso de aneurisma da artéria ilíaca comum e interna direita associado a fístula para veia ilíaca comum, cursando, inicialmente, com edema do membro inferior direito e dispnéia, o que levou ao diagnóstico incorreto de trombose venosa profunda.

Rupture of aortoiliac aneurysms into the iliac vein or vena cava is an uncommon complication. Many signs and symptoms develop as a result of venous hypertension, which makes preoperative diagnosis difficult, such as leg edema, dyspnea, hematuria, signs of renal or cardiac insufficiency. Abdominal bruit, associated with pulsatile mass and abdominal pain, is the key for clinical diagnosis. Preoperative recognition of arteriovenous fistula is important for surgical planning. We report a case of right internal and common iliac artery aneurysm associated with fistula into the common iliac vein. Initial symptoms were right leg edema and dyspnea, which induced to the incorrect diagnosis of deep vein thrombosis.

Anterior ethmoidal artery aneurysm and intracerebral hemorrhage.

The association between the formation of intracranial aneurysms and situations of increased blood flow in certain areas of the brain is well accepted today. It has been seen in association with arteriovenous malformations of the brain, carotid occlusion, and Moyamoya disease. The occurrence of aneurysms in small arteries of the skull base, with the exception of the intracavernous carotid artery, however, is rare. We report a case of a 55-year-old woman who presented with an intracerebral hemorrhage caused by a ruptured anterior ethmoidal artery aneurysm. To the best of our knowledge, this is only the second case of documented intracranial bleeding from such a lesion.
