RESUMO
BACKGROUND: Lower extremity amputation (LEA) is a major surgical procedure with a high risk of significant morbidity and mortality. The objective of this study was to describe mortality and functionality outcomes following this procedure in a developing country. METHODS: This is a retrospective study of all patients undergoing LEA for non-traumatic etiology between 2007 and 2017. Medical records were used to retrieve demographics, comorbidities, and perioperative complications of identified patients. Patients were contacted to follow-up on their medical, postoperative care, and ambulatory status. Mortality and postoperative functionality rates were analyzed. RESULTS: The study included 78 patients. Median follow-up duration was 24 months. Hypertension (81%) and diabetes (79%) were the most common comorbidities. Mortality rates at 30 days, 1, and 5 years were 10.3, 29.2, and 65.5%, respectively. Mortality was significantly associated with age > 70 at amputation (p = 0.042), hypertension (p = 0.003), chronic kidney disease (p = 0.031), and perioperative sepsis (p = 0.01). Only 1.6% of patients were discharged into a specialized care center, and only 27% of patients were ambulatory postoperatively, although 90.5% were fitted with a prosthesis. CONCLUSIONS: Survival following major amputation in a developing country is currently comparable to more developed regions of the world. Major discrepancy seems to exist in ambulatory status following the procedure. Discharge placement policies should be properly set, and rehabilitation centers funding should be increased. Awareness may also be warranted to educate patients and families about the value and positive impact of rehabilitation centers.

We report the case of a 10-year-old girl with Takayasu arteritis who developed acute onset wrist drop diagnosed with a large right axillary artery aneurysm compressing the surrounding structures. Our case is unique because it describes a rare presentation of Takayasu arteritis (axillary aneurysm) in a child that was treated successfully in an unconventional manner by transcutaneous embolisation following failure of trans-arterial approach.

BACKGROUND: Intima-media thickness (IMT) is a well-described marker of cardiovascular disease. In this study we aim to determine whether low-density lipoprotein (LDL) levels and disease-related mutation status can predict IMT in patients with severe familial hypercholesterolemia (FH) referred for or on LDL apheresis. METHODS: Genetic screening, lipid profile testing, and IMT measurements were performed on a series of 33 severe FH patients (19 homozygous) on LDL apheresis treatments (LDL 447 ± 151 mg/dL, age range 6-60 years). Data were then compared with literature IMT-LDL data for normal subjects, mild FH patients, and severe FH patients (18, 41, and 6 studies, respectively). RESULTS: Age-adjusted IMT was linearly related to LDL levels over a wide range of values (<500 mg/dL), except for the severe FH no-apheresis cohort. Alternatively, our severe FH population (mostly on apheresis) did follow the mild FH/control age-adjusted IMT-LDL relation. CONCLUSIONS: In severe FH, measuring LDL levels is more predictive of increased IMT than genetic screening.

Valvular heart disease frequently occurs as a consequence of premature atherosclerosis in individuals with familial hypercholesterolemia (FH). Studies have primarily focused on aortic valve calcification in heterozygous FH, but there is paucity of data on the incidence of valvular disease in homozygous FH. We performed echocardiographic studies in 33 relatively young patients (mean age: 26 years) with homozygous FH (mean LDL of 447 mg/dL, 73% on LDL apheresis) to look for subclinical valvulopathy. Twenty-one patients had evidence of valvulopathy of the aortic or mitral valves, while seven subjects showed notable mitral regurgitation. Older patients were more likely to have aortic valve calcification (>21 versus ≤21 years: 59% versus 12.5%; p = 0.01) despite lower LDL levels at the time of the study (385 versus 513 mg/dL; p = 0.016). Patients with valvulopathy were older and had comparable LDL levels and a lower carotid intima-media thickness. Our data suggests that, in homozygous FH patients, valvulopathy (1) is present across a wide age spectrum and LDL levels and (2) is less likely to be influenced by lipid-lowering treatment. Echocardiographic studies that focused on aortic root thickening and stenosis and regurgitation are thus likely an effective modality for serial follow-up of subclinical valvular heart disease.
RESUMO
In-stent restenosis in a renal artery (RA) of a solitary functioning kidney is a serious complication of RA stenting. Drug-eluting balloons (DEB) have emerged as a novel way to manage restenosis. In this paper, the authors reported the first use of a DEB in the treatment of severe in-stent restenosis and thrombosis of a drug-eluting stent deployed in a RA. The patient presented with oligo-anuria and a serum creatinine (Scr) of 9 mg/dL that improved back to baseline of 2 mg/dL after the successful procedure. The optimal use of DEB in similar cases will have to be determined by larger clinical trials.

High-output cardiac failure secondary to a surgically constructed arteriovenous fistula (AVF) is a rare entity that is usually under-diagnosed in the dialysis population. We herein present a case of a 35-year-old female who was diagnosed with high-output cardiac failure secondary to an AVF and later managed with surgical division of the fistula. Risk factors associated with this entity are discussed, and preventive screening strategies are recommended.
