The Sinus Venosus Veno-Venous Bridge Not a septal defect
\ua9 2023, Sultan Qaboos University. All rights reserved.This review provides an update on the morphology of the sinus venosus defect. It was earlier believed that a \u27common wall\u27 separated the right pulmonary veins from the superior caval vein. In the sinus venosus defects, this wall was absent. Current evidence shows that the superior rim of the oval fossa, rather than forming a second septum or representing a common wall, is an infolding between the walls of the caval veins and the right pulmonary veins. The sinus venosus defect is caused by the anomalous connection of one or more pulmonary veins to a systemic vein. However, the pulmonary vein(s) retain their left atrial connections, leading to a veno-venous bridge that allows interatrial shunting outside the oval fossa. True atrial septal defects are located within the oval fossa or in the anteo-inferior buttress, while sinus venosus defects, ostium defects and coronary sinus defects are morphologically distinct from them

Effect of Transdermal Scopolamine for the Prevention of Postoperative Nausea and Vomiting Associated With Robotic Gynecologic Surgery: A Randomized, Double-Blinded, Placebo-Controlled Trial
Postoperative Nausea and Vomiting in Diagnostic Gynaecological Laparoscopic Procedures: Comparison of the Efficacy of the Combination of Dexamethasone and Metoclopramide with that of Dexamethasone and Ondansetron
BACKGROUND AND OBJECTIVE: This study was conducted in a tertiary
hospital with the aim of comparing the efficacy of a combination of
dexamethasone and metoclopramide with dexamethasone and ondansetron for
the prophylaxis of postoperative nausea and vomiting [PONV] after
diagnostic gynaecological laparoscopic procedures. SUBJECTS AND
METHODS: In this prospective, randomised, double-blind study, 120 women
received either saline I.V. [Group I, n=40]; a combination of
dexamethasone [8 mg] with metoclopramide [10 mg] [Group II, n=40]; or a
combination of dexamethasone [8 mg] with ondansetron [4 mg] [Group III,
n=40] prior to induction of general anaesthesia. PONV was evaluated at
regular intervals. The results were analysed using one-way ANOVA,
post-hoc, Chi-square, Kruskal-Wallace tests and Z test for proportions
where appropriate through a SPSS V.9 package. RESULTS: The 3 groups
were well matched for demographic characteristics. The incidence of
nausea and emesis was significantly lower in Group III {[17.5%, P
<0.02] and [10%, P <0.01] respectively}. Nausea scores were also
lower in Group III [P <0.02]. Rescue anti-emetic requirements were
higher in Group I [P <0.05] as compared to Groups II and III.
CONCLUSIONS: A combination of dexamethasone and ondansetron was more
efficacious as compared to that of metoclopramide and dexamethasone.
The combination of metoclopramide and dexamethasone seems to offer no
additional benefit as compared to saline placeb
Brief Report - Percutaneous Tracheostomy by Guidewire Dilating Forceps Technique: Review of 98 Patients
BACKGROUND: Percutaneous tracheostomy to a large extent has replaced
conventional surgical tracheostomy by virtue of its low incidence of
complications and the rapidity with which the procedure can be
performed at the bedside avoiding transport of critically ill patients
to the operating rooms. Since it is a blind approach, ponchoscopic
guidance has been suggested which might not always be possible due to
logistic reasons. METHODS: A retrospective study of 98 patients who had
guide wire dilating forceps technique of percutaneous tracheostomy
without the aid of a ponchoscope was undertaken. By ensuring the free
mobility of the guide wire at each step of the procedure, a safe
placement of the tracheostomy tube was achieved. RESULTS: The mean
operating time was 3.05 mins [S.D:2.20]. Two patients had peristomal
bleeding as an early complication. 34 patients could be decannulated
with good primary approximation of the stomal tissues [mean: 3.92days,
S.D: 1.46]. There were no deaths or life threatening complications
attributable to this technique. CONCLUSIONS: In the absence of
ponchoscopic guidance, adopting the simple but effective precaution of
free movement of guide wire at each step of the procedure, a safe
tracheostomy tube placement is possible
An Unusual Presentation of Double-Outlet Right Atrium
\ua9 The Author(s) 2024.We describe an unusual example of double-outlet right atrium with separate atrioventricular junctions. The straddling and overriding tricuspid valve had two orifices, and the mitral valve was morphologically normal. An appropriate understanding of the morphology of the atrioventricular junctions, the valves, and the subvalvar apparatus, along with the location of the atrioventricular conduction axis, allowed for successful biventricular repair
A new approach to surgical correction of double-outlet right ventricle with remote interventricular communication
Systemic venous anomalies in a child with a vein of Galen
\ua9 2024 Annals of Pediatric Cardiology.We describe our findings in a child with a vein of Galen malformation, in whom the right superior caval and the azygos veins drained into the roof of the morphologically left atrium. A persistent left superior caval vein drained into the morphologically right atrium through the coronary sinus. The additional presence of dual brachiocephalic veins permitted the deployment of a multifunctional ventricular septal defect occluder device to occlude the right superior caval vein, correcting the right‑to‑left shunt. This also prevented azygos venous drainage into the left atrium
