Background: Type A aortic dissection is a challenging surgical emergency associated with high morbidity and mortality. Many techniques have evolved to repair the dissected sinus segments and restore aortic valve dynamics. Herein, we evaluate the early outcome of a novel technique for reconstruction of dissected aortic root.
Methods: A prospective study was conducted on 300 patients to evaluate the early results of repair of dissected root in type A aortic dissection. The mean age was 59.65±8.52 years, and 76% of patients were males. All patients had four standard steps for aortic reconstruction: 1) commissural resuspension; 2) right coronary sinus reinforcement with pericardial and Dacron bands; 3) non-coronary sinus reinforcement using external Dacron patch; 4) circumferential inversion of adventitial layer of the root. Patients were followed up clinically, echocardiographically, and by CT scan.
Results: The in-hospital mortality was 8%. The mean cross-clamp time was 120±30 minutes, and circulatory arrest time was 25+10 minutes. Twenty-seven patients (9%) experienced postoperative complications, including bleeding and acute kidney injury. During a mean follow-up time of 48±12 months, there were no recurrent aortic dissection, aortic dilatation, pseudoaneurysm, or progression of aortic regurgitation during the entire study period.
Conclusions: This reconstructive technique technically is undemanding, feasible, safe, and durable with good early results. A larger cohort of patients with longer period of follow up should generate a more powerful evaluation of this technique.
Background:
We evaluated furosemide on attenuating lung injury and/or edema during coarctation repair surgery. We evaluated dynamic lung compliance. We measured the degree of lung edema by means of lung ultrasound (LUS). We recorded the (PaO
2
/FiO
2
ratio) as an indicator for oxygenation.
Materials and Methods:
A study was conducted on 56 patients. Patients were divided into two groups: control group (Group C) which did not receive furosemide and furosemide group (Group F) at a dose of 1 mg/kg at induction of anesthesia. Dynamic lung compliance was calculated at induction (Cdyn 1) and at the end of the surgery (Cdyn 2). The (PaO
2
/FiO
2
ratio) was calculated at start and end of surgery as (PF 1) and (PF 2), respectively. LUS was performed after induction (LUS 1) and at the end of the surgery. LUS 2 using the 12 regions method plotting the results on scale from 0 to 36. Mechanical ventilation days were recorded.
Results:
Administering furosemide attenuated the lung injury/edema and other pulmonary complications. Furosemide administration improved the dynamic lung compliance in the F Group compared to the C Group. Furthermore, it increased the (PaO
2
/FiO
2
ratio) in the F Group compared to the C Group. LUS scale values were lower in the F Group compared to the C Group. There was also less postoperative mechanical ventilation days.
Conclusions:
The use of furosemide was accompanied by improved lung injury/edema profile as indicated by a much less drop in dynamic lung compliance, better oxygenation, a more favorable LUS scale with less parenchymal lung affection.
Background: Surgery is considered the treatment of choice for esophageal achalasia as it achieves better and longer-lasting symptomatic relief. Laparoscopic Heller cardiomyotomy is the standard procedure with partial or complete fundoplication as an anti-reflux measure.
Aim of the work:To compare results between Dor and Nissen fundoplication after laparoscopic Heller cardiomyotomy in type II achalasia regarding postoperative GERD and dysphagia.
Patients and methods:This prospective randomized study was conducted on (40) patients who presented to the outpatient clinics suffering from chronic dysphagia from May 2017 to May 2019 with minimal follow for 12 months. Group A (20) patients underwent laparoscopic Heller cardiomayotomy with Dor fundoplication and group B (20) patients underwent laparoscopic Heller cardiomayotomy with Nissen fundoplication.Results: Regarding dysphagia and gastroesophageal reflux no significant differences were noted postoperatively between Dor fundoplication and Nissen fundoplication with Heller cardio-myotomy. At the end of follow-up, dysphagia occurred in 10% and 20% of patients belonging to the Dor and Nissen groups respectively (p=0.517), while reflux occurred in 10 % of patients with Dor fundoplication, with no cases of reflux after the Nissen fundoplication (p=0.163).
Conclusion:Dor and Nissen fundoplication after heller cardiomyotomy showed good control of postoperative reflux with non-significant dysphagia if done properly. The choice of associated anti-reflux procedure is up to the surgeon's preference and experience.
