Background: We report our experience with the surgical closure of late post-pneumonectomy bronchopleural fistula (PBF) using our own method of coverage of the bronchial stump: Pedicled pericardial flap in combination with fibrin glue.
Methods: We reviewed the surgical results of 33 patients who underwent surgical closure of PBF by thoracotomy access using three methods: Myoplasty (MYO)-12, omentoplasty (OMT)-10, and pedicled pericardial flap (PPF) with fibrin glue-11. Post-operative follow up was six months.
Results: The patients' demography was comparable among the groups. The diameter of the fistulas ranged from 5 mm to total dehiscence. The mean time of the fistula manifestation (in weeks) was 21.5 in the MYO group, 19.50 in the OMT, and 20.1 in the PPF group. The shortest period of hospital drainage of the pleural space was noted in the PPF group. Healing of the fistula was obtained in 66.67% in the MYO group, 80% in the OMT, and 100% in the PPF group. The number of complications was similar in all groups. The hospitalization time was significantly shorter in the PPF group (13.00 d) versus the MYO group (19.58 d) and the OMT (20.01 d). Overall mortality rate was 18.18%; 33.33% of the patients in the MYO group and 20% in the OMT group died. There were no hospital deaths in the PPF group.
Conclusion: Pericardial flap supported by fibrin glue can be an effective method adjunctive to the treatment of postpneumonectomy PBF in selected patients. Compared with other methods of bronchial stump coverage (omentopasty and myoplasty), this one showed a higher percentage of healing of the fistulas and shorter duration of hospital drainage and hospitalization.

Methods of bronchial stump buttressing in post-pneumonectomy bronchopleural fistula prevention: a systematic review.

Department of Thoracic Surgery, Poznan University of Medical Sciences, Poland.
Article Synopsis
- The bronchopleural fistula (BPF) is a serious complication that can occur after pneumonectomy, often addressed through various surgical buttressing techniques to improve healing.
- A review of literature on this topic included 27 articles, but only 16 were suitable for analysis due to factors like small sample sizes and irrelevant surgical procedures.
- The results indicated that three studies found significant benefits of using bronchial stump buttressing to reduce BPF risk, while the rest provided descriptive statistics or assessed blood perfusion in the tissue used.

Article Synopsis
- The study aimed to evaluate the safety and effectiveness of a modified Warden procedure for reconstructing the superior vena cava (SVC) in patients.
- A total of 26 patients (ages 0.3 to 47 years) underwent the surgery, with successful discharge and no deaths or serious complications reported during a median follow-up of 47 months.
- The modified technique using autologous pericardial patches showed promising results, as it corrected the connection between the pulmonary veins and SVC while minimizing risks, although some patients experienced temporary pressure increases post-surgery.

Article Synopsis
- A 3-year-old male standard poodle mix was presented with severe health issues including vomiting, difficulty breathing, and lethargy, which led to a diagnosis of a peritoneal pericardial diaphragmatic hernia (PPDH) involving the liver and gallbladder.
- Emergency surgery revealed serious complications including a necrosed liver lobe, gallbladder issues, and suspected right ventricular aneurysms, which were treated during the operation.
- Post-surgery, the dog experienced ventricular arrhythmia but was successfully managed and discharged after 4 days, showing good recovery after 12 months; this case highlights the rarity and risks associated with right ventricular aneurysms in dogs.
