Project description:Introduction. It is rare for a popliteal artery aneurysm (PAA) to present with rupture. This case reports a longer-term success in the management of a large ruptured popliteal artery aneurysm with an endovascular approach, with a literature review of management of such cases. Case Report. An 80-year-old man presented to the accident and emergency department with pain and swelling behind the left knee and at the back of the thigh. An ultrasound scan and subsequent CT angiogram revealed a large 9.4?cm ruptured PAA. The patient had significant comorbidities deeming him unfit for a major surgical intervention of drainage of haematoma and exclusion bypass. Therefore, he underwent urgent endovascular treatment of the ruptured PAA with a covered stent graft. A follow-up duplex scan at 1 year showed a patent stent with no evidence of endoleak, and the patient remained asymptomatic. A clinical follow-up at 18- and 24-month postprocedure showed a patent stent graft and complete resolution of haematoma. Conclusion. Whilst open repair with exclusion bypass may still be a treatment of choice, an endovascular approach is both safe and effective in the management of a ruptured PAA in an unfit patient with an acceptable longer-term outcome.

Project description:BackgroundIsolated true aneurysms in the superficial femoral artery (SFA) have rarely been reported. Most cases are undiagnosed until rupture or the occurrence of complications.Case summaryA 36-year-old woman presented with a palpable, pulsating mass on her right thigh which had increased in size over 2 months. She also had a swollen right leg and mild claudication (Stage II in Rutherford classification). For 2 months, the patient was treated by manual massage, acupuncture, and extracorporeal shock wave therapy in local clinics. Bed-side ultrasonography identified a 3.4-cm sized true aneurysm of the right SFA. There were no other aneurysms in arteries from head to toe. There was no evidence of atherosclerotic risk factors or connective tissue disease. The patient was successfully treated by a covered stent graft implantation without any complications.DiscussionIsolated true aneurysm in the SFA is rare and tends to go undiagnosed especially in young women. Ultrasonography is an easy and useful diagnostic tool for differential diagnosis of thigh mass. In this case, endovascular treatment was safely applied for a true aneurysm without rupture.

Project description:Background:Coronary artery fistulas are rare and most commonly asymptomatic; however, they can become enlarged and rupture in some cases. Case summary:We report a case of a 51-year-old woman who was brought to our hospital unconscious in an ambulance. Cardiac tamponade caused by the rupture of an aneurismal coronary-pulmonary artery fistula (CPAF) was detected by contrast-enhanced computed tomography and confirmed by invasive coronary angiography. Due to prompt diagnosis and subsequent surgical intervention, the patient's condition was rapidly improved, and she was discharged from the hospital. Discussion:Coronary-pulmonary artery fistula aneurysm rupture requires rapid diagnosis and treatment, and thus, in cases with cardiac tamponade and coronary aneurysm, CPAF aneurysm rupture should be considered.

Project description:Giant coronary artery aneurysm (CAA) is a relatively uncommon disease that is defined by a focal dilation of at least 20 mm and characterized by various clinical symptoms. However, cases presenting primarily with hemoptysis have not been reported. A man in his late 20 s suffering from persistent chest pain for over 2 months was transferred to our emergency department for intermittent hemoptysis lasting for 12 h. Bronchoscopy detected fresh blood in the left upper lobe bronchus without a definite bleeding source. Magnetic resonance imaging (MRI) demonstrated a heterogeneous mass and the high-intensity signals suggested active bleeding. coronary computed tomography (CT) angiography demonstrated a giant ruptured CAA wrapped in a large mediastinal mass Coronary angiography confirmed the CAA originating from the left anterior descending artery. The patient underwent an emergency sternotomy and an enormous hematoma arising from a ruptured CAA densely adhering to the left lung was identified. The patient recovered uneventfully and was discharged on the 7th day later. The ruptured CAA masquerading as hemoptysis highlights the indispensability of multimodality imaging for accurate diagnosis. Urgent surgical intervention is desirable in such life-threatening conditions.

Project description:Background: Anomalies of the middle cerebral artery (MCA) are rare; among the different types of anomalies, the aplastic or twig-like (Ap/T) MCA is extremely rare and has been reported under various names, including aplastic, unfused, or rete type anomaly. The occurrence of a brain aneurysm associated with this anatomic variant is an even rare event, and probably their development and rupture are related to hemodynamic stress of the tinny wall of vessels forming the network. Case Description: We present a 43-year-old male patient with an explosive and persistent right orbitofrontal headache. A computed tomography showed a right frontobasal hematoma with intraventricular disruption. Magnetic resonance angiography showed a right MCA aneurysm and what seems to be a MCA trunk stenosis. Cerebral digital subtraction angiography demonstrated a plexiform arterial network and one aneurysm arising from the network. The patient was successfully treated by surgical clipping to evacuate the hematoma and to prevent further intracranial hemorrhages. Conclusion: The Ap/T-MCA may be associated with hemodynamic stress with a significant effect through the tinny wall of the vessels causing hemorrhage or leading to the formation and rupture of cerebral aneurysms. Based on a correct diagnosis of the anomaly, treatment can be completed successfully through different standard methods.

Project description:BackgroundPopliteal artery pseudoaneurysm is a state of vascular wall rupture in the popliteal artery. It is generally a rare situation and the most common etiologic factor is iatrogenic causes.Case presentationThis case report presents a successful diagnosis and management of a 31-year-old patient who was presented with a mass behind the knee, three months after femoropopliteal bypass for the treatment of a gunshot to the knee. An endovascular approach using coils was utilized for the patient, which led to complete remission for the patient.DiscussionThe current patient had two primary therapeutic challenges: bleeding and hematoma growth, clot development causing blood flow restriction, and limb ischemia. Pseudoaneurysm also caused internal inflammation, which increased the risk of thrombosis and bypass graft damage during open surgery. Due to the risk of recurrence and graft damage, ultrasound-guided compression was not possible. Thus, endovascular therapy was preferred.ConclusionThe endovascular approach using coils is an option for the management of PAP. However, the endovascular approach should be considered carefully according to the patient's status.

Project description:IntroductionBrucella is a genus of aerobic Gram negative bacteria that causes the disease brucellosis. It is considered a zoonotic infection transmitted to humans by ingestion of unpasteurised dairy products. Although aortic involvement is rarely seen, it can be a life threatening complication of this disease. This case report describes a ruptured aneurysm of the common iliac artery (CIA) due to secondary infection by Brucella melitensis.ReportA 79 year old man with a known isolated aneurysm of the CIA presented with acute abdominal pain. Contrast enhanced computed tomography (CT) revealed rupture of the aneurysm. The patient underwent prompt endovascular repair. Several weeks after an uneventful recovery, the patient presented with spiking fever and abdominal discomfort. CT revealed an abscess anterior to the CIA. Blood and pus cultures grew B. melitensis. In recurrent re-admissions, conservative antibiotic therapy proved to be insufficient. Eventually, neo-aorto-iliac system (NAIS) reconstruction using bilateral femoral veins was performed to provide definitive treatment four months after initial presentation.ConclusionAlthough Brucella infected aneurysms are rare, they are associated with life threatening disease. Diagnosing this type of brucellar infection can be challenging owing to the long incubation time needed for blood and tissue cultures. Definitive treatment of these aneurysms often needs open surgery and antibiotics for complete treatment. Vigilant surveillance is required to monitor for post-operative complications such as graft infection, recurrent (false) aneurysm, and abscess formation.

Project description:BackgroundCarotid free-floating thrombus (CFFT) is a rare but sometimes emergent condition. There has been controversy over the optimal treatment strategy. Emerging evidence suggests that endovascular thrombectomy (EVT) may be an alternative to surgery. Accurate alignment of the aspiration catheter and thrombus during EVT is critical but has, so far, remained unresolved.Case summaryThis is a rare case of CFFT presenting with acute right-sided facial droop and moderate dysarthria in a 77-year-old man. He was in sinus rhythm with a blood pressure of 110/82 mmHg. Both non-contrast CT (NCCT) and head CT angiography (CTA) were unremarkable, while whole-brain CT perfusion (WB-CTP) suggested left hemisphere core infarction. Delayed imaging of the left internal carotid system by 4D-CTA suggested severe proximal obstructive disease, as confirmed by carotid CTA and ultrasonography. The initial two aspirations under DSA were invalid due to the challenging anatomical angle between the thrombus and the catheter. The success of CFFT removal was achieved with a pressure-assisted ultrasound-guided approach that helps to compress the catheter tip toward the thrombus.ConclusionWe innovatively report a successful ultrasound-guided EVT for CFFT. Ultrasound assistance can provide quick and effective guidance and may guide tailored aspirations during EVT.

Project description:Moyamoya syndrome (MMS) refers to the moyamoya vascular disease associated with various systemic diseases and conditions, including sickle cell anemia, Fanconi anemia and iron deficiency anemia. However, the association between MMS and other hemoglobinopathies is less frequently observed. MMS, like moyamoya disease, is a cerebrovascular condition that is characterized by chronic progressive stenosis or occlusion at the ends of the bilateral internal carotid arteries, anterior cerebral arteries and the beginning of the middle cerebral arteries, and is secondary to the formation of an abnormal vascular network at the base of the skull. Patients with MMS are prone to thrombosis, aneurysm and bleeding. The present study reports the case of a 43-year-old man with α-thalassemia who presented with moyamoya vessels with a ruptured aneurysm bleeding into the ventricle. α-thalassemia is considered as an extremely rare but potential cause of MMS. Since MMS is a progressive disease, early diagnosis and treatment is vital to prevent the disease from worsening.
