background: the presence of rennin-angiotensin components in mammalian ovaries and their involvement in ovarian physiology have been established. in the present study, effects of angiotensin ii (ang ii) on sodium-potassium adenosine triphosphatase (na+/k+/atpase) expression and development of sheep embryos was evaluated. methods: the abattoir-derived cumulus oocyte complexes (coc) were randomly...

Objective: To evaluate the results after total cavopulmonary connection (TCPC) in small children, our clinical experience was retrospectively reviewed. Methods: Of 164 patients undergoing TCPC, the body weight at operation was less than 10 kg (8.8 ^ 1.1 kg) in 54, including 21 with visceral heterotaxy. The superior caval vein (SVC) was anastomosed to the pulmonary arteries in a bidirectional fa...

PURPOSE Implementing an inferior vena cava (IVC) filter is a relatively safe procedure but potential negative long-term effects. The complications for filter retrieval have been noted. We examined filter characteristics on pre-retrieval computed tomography (CT) that were associated with complicated retrieval (CR) of IVC filters. MATERIALS AND METHODS A retrospective review of IVC filter retri...

The development of the inferior vena cava (IVC) includes contributions from diverse embryonic venous precursors and involves major cross connections and left-to rightshunting. This complex process is vulnerable to errors. However, congenital malformations of the IVC are reported to be rare. Most of these malformations are accidental findings in chest and abdomen imaging. Anomalies of the IVC ar...

The present study investigated the effect ofL-carnitine supplementation during different pre-implantation stages on bovine embryo development rate and quality. Good morphologically cumulus-oocyte complexes (n=2126) recovered from slaughterhouse ovaries were matured, fertilized in vitro and presumed zygotes were further cultured in vitro (IVC) in CR1-aa media till day 8. For the setup of the stu...

p b c m m f c Background. Several variations of the total cavopulmoary connection (TCPC) have been investigated for faorable fluid mechanics and flow distribution. This study resents a hemodynamically optimized TCPC configuraion code-named “OptiFlo.” Featuring bifurcated vena ava (superior venacava to inferior vena cava SVC/IVC), t was designed to lower the fluid mechanical power osses in the c...

The incidence of small renal masses (≤ 4 cm) has increased over the past three decades. Partial nephrectomy remains the standard for treatment of such lesions, but increased attention is being given to patients who may benefit from active surveillance, given the low risk of metastatic spread and traditionally slow growth rates. Patients with significant comorbidities and the elderly are often c...

In the embryonic heart, the primitive atrium is considered to receive the bilateral sinus horns including the upper terminal of the inferior vena cava (IVC). To reveal topographical anatomy of the embryonic venous pole of the heart, we examined horizontal serial paraffin sections of 15 human embryos with crown-rump length 9-31 mm, corresponding to a gestational age of 6-7 weeks or Carnegie stag...

Hepatectomy for secondary liver cancer that has invaded the inferior vena cava (IVC) can be the only way to achieve long-term survival. We describe a method for hepatectomy combined with partial IVC resection without venous bypass circulation and an in situ graft-trimming method to avoid graft size mismatch after reconstruction. We carried out left hepatectomy extended to segment 1 with partial...
