Drenaje venoso pulmonar anómalo parcial del pulmón izquierdo: Corrección mediante toracotomía sin circulación extracorpórea / Partial anomalous pulmonary venous drainage of the left lung: Correction through thoracotomy without extracorporeal circulation

Se describen dos casos de drenaje venoso pulmonar anómalo parcial del pulmón izquierdo a la vena vertical, la cual drena a su vez a la vena innominada, en dos niños de 6 y 8 años respectivamente. Se exponen el cuadro clínico, los hallazgos del cateterismo, la evolución clínica y el resultado postquirúrgico; adicionalmente, se hace una revisión de la literatura.

Two cases of partial anomalous pulmonary venous drainage of the left lung to the vertical vein, which in turn drains to the innominate vein, are described in two 6 and 8 year old children. The clinical picture, catheterization findings, clinical course and postoperative outcome are discussed and a review of the literature is made in addition.

First-trimester uterine artery Doppler velocimetry in the prediction of birth weight in a low-risk population.

OBJECTIVE: To study the relationship between first-trimester uterine artery (UtA) Doppler velocimetry and birth weight in an unselected, low-risk obstetric population. METHODS: This is a prospective study of 415 low-risk pregnant women who underwent a first-trimester ultrasound evaluation between 11 and 13 weeks of gestation. Blood flow velocimetry waveforms from both UtAs were obtained and the pulsatility index (PI) measured and recorded. Clinical records were reviewed for pregnancy outcomes. Birth weight was expressed as z-scores, and the Spearman correlation coefficient (ρ) was used to calculate the relationship between the mean, delta, and lowest UtA PI values and birth weight. RESULTS: There was no correlation between the mean and delta UtA PI values and birth weight. However, a significant correlation between the lowest UtA PI value and birth weight (ρ = -0.121; p = 0.013) was noted. CONCLUSIONS: Our study found a clinically significant correlation between the lowest UtA PI value and birth weight in an unselected, low-risk pregnant population. Because fetal growth is a multifactorial process in which placentation is only one of the factors involved, the use of a single parameter such as Doppler velocimetry remote from the delivery to predict birth weight in a low-risk population seems to be less useful than in the high-risk population.

[Laparoscopic resection of an interstitial ectopic twin pregnancy resection: the role of barbed sutures in haemostatic control]. / Utilidad de la sutura barbada en el tratamiento de pacientes con embarazo ectópico por vía laparoscópica.

Interstitial pregnancy is a dangerous and uncommon variation of ectopic pregnancy occurring in the interstitial part of the fallopian tube and extending beyond the muscular layer of the uterus. This ectopic pregnancy-related mortality rate has been reported to be as high as 2%-2,5% due to complications involving bleeding and hypervascularity. No prospective clinical trials have evaluated available treatment options for interstitial ectopic pregnancy due to its low incidence; there is thus no consensus regarding optimal treatment. Surgical treatment can be divided into conservative approaches, such as cornuectomy or cornuostomy, and radical approaches such as hysterectomy. However, intraoperative hemorrhage is an ever-present risk, regardless of the surgical approach adopted. This paper presents a case involving a patient who underwent laparoscopic resection of an interstitial twin ectopic pregnancy; a barbed suture pursestring was used which proved useful during the surgical technique and improved hemostasia.
