RESUMEN
An advanced abdominal pregnancy is defined as an extrauterine pregnancy over twenty weeks gestation with a fetus living, or showing evidence of having once lived, in the mother's abdominopelvic cavity. Our case is a 35-year-old patient with a 23-week extrauterine pregnancy, with a congenital head defect (scaphocephaly and hydrocephalus), located in the left side of the maternal abdomen with a period of gestation of 23 weeks, who underwent preoperative imaging with contrast-enhanced multidetector computed tomography (CE-MDCT). CT imaging provided significant information on the placenta and its arterial supply/venous drainage and confirmed the presence of an arteriovenous malformation of the right uterine artery. CT imaging also allowed planning of preoperative uterine artery coil embolization.
RESUMEN
BACKGROUND: Variations in the anatomy of hepatic veins are of interest to transplant surgeons, interventional radiologists, and other medical practitioners who treat liver diseases. The drainage patterns of the right hepatic veins (RHVs) are particularly relevant to transplantation services. AIM: The aim was to identify variations of the patterns of venous drainage from the right side of the liver. To the best of our knowledge, there have been no reports on RHV variations in in a Caribbean population. METHODS: Two radiologists independently reviewed 230 contrast-enhanced computed tomography scans performed in 1 year at a hepatobiliary referral center. Venous outflow patterns were observed and RHV variants were described as: (1) Tributaries of the RHV; (2) Variations at the hepatocaval junction (HCJ); and (3) Accessory RHVs. RESULTS: A total of 118 scans met the inclusion criteria. Only 39% of the scans found conventional anatomy of the main hepatic veins. Accessory RHVs were present 49.2% and included a well-defined inferior RHV draining segment VI (45%) and a middle RHV (4%). At the HCJ, 83 of the 118 (70.3%) had a superior RHV that received no tributaries within 1 cm of the junction (Nakamura and Tsuzuki type I). In 35 individuals (29.7%) there was a short superior RHV with at least one variant tributary. According to the Nakamura and Tsuzuki classification, there were 24 type II variants (20.3%), six type III variants (5.1%) and, five type IV variants (4.2%). CONCLUSION: There was significant variation in RHV patterns in this population, each with important relevance to liver surgery. Interventional radiologists and hepatobiliary surgeons practicing in the Caribbean must be cognizant of these differences in order to minimize morbidity during invasive procedures.
RESUMEN
Cervical cystic lymphangiomas are rare benign tumors that pose a formidable challenge to surgeons confronted with managing this uncommon entity. Due to the intimacy with which these cystic lesions blend with critical cervical structures, a considerable number of patients who undergo surgical management are often plagued with recurrence and morbidity. As a result, doxycycline sclerotherapy has become an attractive, safe, and effective alternative as a primary treatment modality in a select group of pediatric patients. This case report presents an 18-month-old patient with a large cervical cystic hygroma that was effectively treated with exclusive doxycycline sclerotherapy.
