The frequency and gender distribution of thoracic aortic aneurysm as a cardiovascular manifestation of loss-of-function (LOF) X-linked FilaminA (FLNA) mutations are not known. Furthermore, there is very limited cardiovascular morbidity or mortality data in children and adults. We analyzed cardiac data on the largest series of 114 patients with LOF FLNA mutations, both children and adults, with periventricular nodular heterotopia (PVNH), including 48 study patients and 66 literature patients, median age of 22.0 years (88 F, 26 M, range: 0-71 years), with 75 FLNA mutations observed in 80 families. Most (64.9%) subjects had a cardiac anomaly or vascular abnormality (80.8% of males and 60.2% of females). Thoracic aortic aneurysms or dilatation (TAA) were found in 18.4% (n = 21), and were associated with other structural cardiac malformations in 57.1% of patients, most commonly patent ductus arteriosus (PDA) and valvular abnormalities. TAA most frequently involved the aortic root and ascending aorta, and sinus of Valsalva aneurysms were present in one third of TAA patients. Six TAA patients (28.5%) required surgery (median age 37 yrs, range 13-41 yrs). TAA with its associated complications was also the only recorded cause of premature, non-accidental mortality in adults (2 M, 2 F). Two adult patients (1 F, 1 M, median 38.5 yrs), died of spontaneous aortic rupture at aortic dimensions smaller than current recommendations for surgery for other aortopathies. Data from this largest series of LOF FLNA mutation patients underscore the importance of serial follow-up to identify and manage these potentially devastating cardiovascular complications.
A 3D CTA reconstructed from 16-channel MDCT images clearly revealed perigastric vascular anatomy in all cases, which is important for laparoscopic gastrectomy. Three-dimensional CTA is useful for the preoperative visualization of laparoscopic gastrectomy.
We treated a 66-year-old woman with hepatic encephalopathy secondarily induced by an intrahepatic portosystemic venous shunt (IPSVS). In serial observations, the volume of the liver became smaller and encephalopathy could not be controlled with conservative therapy. We occluded the IPSVS successfully using percutaneous transcatheter embolization with micro coils. Following embolization, encephalopathy disappeared and blood flow of all branches of portal vein improved. In cases with an IPSVS without liver cirrhosis, blood flow in the portal vein and liver volume must be followed carefully, and interventional radiology may be considered effective in those who do not show a satisfactory response to conservative therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
