An 8-year-old male patient was sent to the catheterization laboratory for assessment of a partial anomalous pulmonary venous connection found by echocardiography. During the intervention, cineangiogram revealed left pulmonary veins draining to the right atrium through left innominate and vertical veins. Despite this anatomical feature, these pulmonary veins were also ...

Embolization is a rare but serious complication of venous central catheters in pediatric oncology. The reported cases in the literature are due in common to catheter ruptures. The most common cause is constant compression of the costoclavicular arch, known as "pinch-off" syndrome. We report a seven-year-old boy in whom embolization ...

An 8 month old female with hypoplastic left heart syndrome had undergone bidirectional cavopulmonary anastomosis at the age of 4 ½ months and presented with a new continuous flow murmur on routine follow up. Diagnostic catheterization demonstrated a fistula between the left atrial appendage and the neo-aortic arch. The fistula ...

We report our single-center experience in treating 101 type II endoleaks with ethylene-vinyl-alcohol copolymer (EVOH, Onyx). In all, 65 endoleaks were embolized transarterially, and 36 were treated through a translumbar approach. Since the first transarterial embolization, when we began attempts to treat all patients initially via common femoral access, 58 ...

Endoleak is the most common complication after endovascular aneurysm repair. The most common type of endoleak, a type II endoleak, typically follows a benign course and is only treated when associated with increasing aneurysm size. In this case report, we describe a ruptured abdominal aortic aneurysm due to a late, ...

Type II alveolar epithelial (AT-II) cells produce pulmonary surfactant proteins that are essential for alveolar function. AT-II is a major target in lung injury, and ineffective repair of damaged alveolar epithelia has been postulated to cause pulmonary fibrosis. Previous studies have shown that tyrosine phosphatase Shp2 is expressed highly in ...

Abdominal aortic aneurysm repair by endovascular techniques have gained wide acceptance as a treatment option. A potential well-known complication of endovascular repair includes endoleak. Specifically, type II endoleak, which is described as retrograde flow into the aneurysm sac through collateral vessels, can occur in up to 30% of patients. Certain ...

Type II endoleak after endovascular repair of an infrarenal aortic aneurysm (EVAR) may be difficult to diagnose and treat in the best of circumstances. Management is more difficult in the patient with significant renal insufficiency. We report an 81-year-old man with stage IV chronic kidney disease and a rapidly expanding, ...

Endoleaks are one of the most common reasons for reinterventions and failure after endovascular aneurysm repair (EVAR). Current classifications divide endoleaks into type I-V but a more pragmatic definition is of direct and indirect endoleaks. Direct endoleaks (type I and III) transmit direct systemic pressure to the aneurysm sac and ...

Hypoxic pulmonary hypertension is a life-threatening emergency if untreated. Consistent pulmonary hypertension also leads to arteries and ventricular remodeling. The clinical therapeutic strategy for pulmonary hypertension and the corresponding remodeling mainly interacts with NO, angiotensin II (Ang II) and elevated endothelin (ET) targets. In the present study, we evaluated the ...

Two patients with a patent foramen ovale associated with redundant and fenestrated atrial septal aneurysms and a history of multiple transient ischaemic episodes underwent percutaneous device closure using the Atriasept(™) II septal occluders. After release of the devices, the aneurysms were stabilised and no residual shunts were detected. Certain clinical ...

The current study describes the incidence and phenotype of plaque rupture complications in murine vein grafts. Since matrix metalloproteinases (MMPs) are highly involved in atherosclerotic plaque vulnerability and plaque rupture, we hypothesized that this model can be validated by overexpression of the MMP inhibitor TIMP-1. First we studied 47 vein ...

Current practice guidelines recommend that pulmonary blastomycosis be treated with antifungal agents such as amphotericin B and itraconazole. Echinocandins are not recommended because of poor in vitro activity against Blastomyces dermatitidis and lack of supporting clinical data. We report a case of chronic pulmonary blastomycosis treated successfully with caspofungin.

Performing Percutaneous Coronary Intervention (PCI) in arteries with complex anatomy remains a clinical problem. In particular tortuosity within a coronary vessel is frequently encountered and can hamper delivery of balloons or stents to coronary stenoses. This has led to the development of a number of adjuvant devices to assist stent ...

Anatomic variations of the inferior vena cava (IVC) are found in 3-5% of the population. IVC duplication is a well-known anatomic variation that is important when relevant procedures are being planed. Therefore, the identification of IVC anomalies should be checked prior to pertinent interventions. We report two cases of dual ...

A 29-year-old woman with two mechanical valve prostheses was referred to our institution for sudden and self-resolved diplopia 2 weeks after childbirth. From the beginning of pregnancy, nadroparin was started instead of warfarin. The echocardiogram performed at hospital admission revealed a severe aortic prosthesis regurgitation due to incomplete leaflet apposition ...

Current data suggest microembolization to the brain may result in long-term cognitive dysfunction despite the absence of immediate clinically obvious cerebrovascular events. We reviewed a series of patients treated electively with carotid endarterectomy (CEA), carotid artery stenting (CAS) with distal filters, and carotid stenting with flow reversal (FRS) monitored continuously ...

Iliofemoral deep venous thrombosis (DVT) secondary to congenital caval abnormalities is uncommon but should be suspected in younger patients presenting with bilateral DVT. Prior reports have described thrombolytic therapy and angioplasty for noncongenital caval occlusion and intraluminal recanalization for suspected congenital caval obstruction. A novel case is described of a ...

Iliac vein compression syndrome (CS) is a rare cause of deep venous thrombosis. It is caused by an anatomic anomaly in which the right common iliac artery overlies the left common iliac vein causing mechanical compression. Subsequent endothelial changes within the vessels have the potential to spur thrombus formation. Aggressive ...
