Venous thromboembolic and bleeding complications among pregnant women with Klippel-Trenaunay syndrome.

BACKGROUND: Klippel-Trenaunay syndrome (KTS) is a vascular malformation overgrowth syndrome characterized by capillary malformation, venous malformation, and limb overgrowth, with or without lymphatic malformation. Patients are at an increased risk of hemorrhage and venous thromboembolism (VTE). Consequently, women with this condition often are counseled to avoid pregnancy, but minimal data are available on the relationship between pregnancy, VTE, and bleeding risk. OBJECTIVE: To review the risk of VTE and bleeding in pregnant and nulligravid women with KTS. METHODS: A retrospective medical record review was performed of women with KTS, aged ≥18 years, evaluated at Mayo Clinic Rochester, Minnesota, from August 1945 to April 2018. RESULTS: We identified 75 women with ≥1 pregnancy and 64 nulligravid women. VTE prevalence was 14 of 70 (20%) for women with a history of pregnancy and 16 of 64 (25%) for nulligravid women (P = .93). Among the 70 women with a history of pregnancy, 7 of 18 VTE events (39%) occurred in association with pregnancy, with VTE affecting 7 of 151 pregnancies (4.6%). Significant bleeding prevalence was 6 of 70 (8.6%) for women with a history of pregnancy and 6 of 64 (9.4%) for nulligravid women (P = .54). LIMITATIONS: This was a retrospective review. CONCLUSION: The prevalence of VTE and bleeding was similar in patients with KTS, irrespective of pregnancy status.

Identifying barriers to follow-up eye care for children after failed vision screening in a primary care setting.

PURPOSE: To identify barriers to follow-up eye care in children who failed a visual acuity screening conducted by their primary care provider. METHODS: Children aged 3-14 years who failed a visual acuity screening were identified. A phone survey with the parent of every child was conducted 4 months after the screening. Family demographics, parental awareness of childhood eye diseases and eye care for children, and barriers to follow-up eye care were assessed. RESULTS: Of 971 children sampled, 199 (20.5%) failed a visual acuity screening. The survey was completed by the parents of 58 children (29.1%), of whom 27 (46.6%) presented for follow-up examination. The most common reason for failure to follow-up was parental unawareness of screening results (29.3%). Follow-up rates were higher in children with previous eye examinations than in those without (81% versus 17%; P = 0.005) and in children who waited <2 months for a follow-up appointment than in those who had to wait longer (100% versus 63%; P = 0.024). Child's sex, ethnicity, and health insurance status, parent's marital, education and employment status, household income, and transportation access were not associated with statistically significant different follow-up rates. CONCLUSIONS: Parental unawareness of a failed visual acuity screening is an important barrier to obtaining follow-up. Strategies to improve follow-up rates after a failed visual acuity screening may include communicating the results clearly and consistently, providing education about the importance of timely follow-up, and offering logistic support for accessing eye appointments to families.
