Pulmonary sequestration and surgical treatment.

Pulmonary sequestration is nonfunctioning, abnormal pulmonary tissue existing inside or outside the visceral pleura. It is not connected to the tracheobronchial tree. In this study, the results of 8 patients, who were diagnosed with pulmonary sequestration and treated during hospitalization in Gülhane Military Medical Academy between 1996 and 2003, were reported. Sex, age, symptoms, diagnostic approach, operative findings, procedures and postoperative outcomes were reviewed. No postoperative complications were seen. In the long-term follow-up all patients were seen to be asymptomatic. We believe surgical resection is mandatory in order to avoid infection and destruction of the normal pulmonary parenchyma even in asymptomatic cases. Furthermore, when infection occurs, major resection such as lobectomy may be necessary rather than segmentectomy or wedge resection, which involves removal of minimal pulmonary parenchyma.

Bronchial artery embolization: experience with 10 cases.

PURPOSE: To report our experience with 10 cases of bronchial artery embolization (BAE). MATERIALS AND METHODS: The study included 18 cases (11 men and 7 women between 21 and 81 years of age, average 52 years), whose massive hemoptyses could not be controlled with conservative and bronchoscopic methods and were sent to the digital subtraction angiography unit between August 2002 and May 2004. Of these 18 cases, BAE was performed in 10 (7 men and 3 women between 21 and 78 years of age, average 54.2 years). An aortogram with a 5F pigtail catheter and a selective bronchial angiogram with a 4F glide Cobra (C2) catheter was obtained in every case. The same C2 catheters that had been used for bronchial angiography were also used for BAE in 7 cases. Hydrophilic microcatheters were additionally needed for BAE in the other 3 cases. Particles > 250 microns (polyvinyl alcohol [PVA], Embosphere microspheres), mechanical coils, or a combination of both were used for BAE. RESULTS: The etiologies of 10 cases in which BAE was performed were tuberculosis (n=3), sarcoidosis (n=3), bronchiectasis (n=2), and malignancy (n=2). Arterial bronchial pathology was also seen in the non-selective angiographic studies of 4 of the 10 BAE cases. Hemoptysis was controlled in all BAE cases in the first session. Recurrences were observed in 2 cases that were embolized with only mechanical coils during the first month follow-up and hemoptysis was again controlled with microparticle embolization with Embosphere microspheres. All 10 cases were followed- up for 1-21 months (average, 8 months). CONCLUSION: Non-selective angiographic examination alone, is not sufficient enough to detect the vascular pathology causing a massive hemoptysis. A selective study must be performed in every case. The cost of angiography can be lowered by using the same 4F glide C2 catheter for BAE. It may not be safe to use only mechanical coils in BAE cases. There is a need for studying additional cases to have more definitive conclusions.

Surgical management of bronchiectasis: analysis and short-term results in 238 patients.

OBJECTIVE: Bronchiectasis is defined permanent dilatations of bronchi with destruction of the bronchial wall. It is still a major cause of morbidity and mortality in developing countries. The aim of this retrospective study is to present our surgical experiences, the early and long-term results of 238 patients with bronchiectasis during a 10-year period. METHODS: We reviewed the medical records of 238 patients who underwent surgical resection for bronchiectasis between January 1992 and December 2001, at Gülhane Military Medical Academy (GMMA) Thoracic Surgery Department. Variables of age, sex, symptoms, etiology, and type of operation, mortality, morbidity and the result of surgical therapy were analyzed. RESULTS: There were 205 (86.13%) male and 33 (13.87%) female patients with an average age of 23.7 and a range of 15-48 years. The presenting symptoms were productive cough in 133 (55.88%), fetid sputum in 116 (48.73%), recurrent infections in 84 (35.29%), and hemoptysis in 39 (12.18%) patients. The disease was bilateral in 31 patients (13.02%) and mainly confined to the lower lobes in 162 (68.06%). The surgical treatment was as follows: pneumonectomy in 13 patients (5.46%), lobectomy in 189 (79.40%), lobectomy+segmentectomy in 31 (13.02%), and wedge resection or segmentectomy in five (2.1%). Staged bilateral thoracotomy was used in 14 patients. There was no operative mortality. Complications occurred in 21 patients and the morbidity rate was 8.82%. Complete resection was achieved in 154 (64.7%) patients. Follow-up data were obtained for 229 (96.21%) of the patients. Nine patients were lost to follow-up. The mean follow-up of these patients was 9 months (range, 3 months to 4 years). The symptoms disappeared in 189 patients (79.41%) and 29 patients (12.18%) had improved, whereas 11 patients (4.62%) had no improvement. Significantly better results were obtained in patients who had undergone a complete resection. CONCLUSIONS: Surgical resection for bronchiectasis can be performed with acceptable morbidity and mortality at any age. The involved bronchiectatic sites should be resected completely for the optimum control of symptoms.

Increased damage from rifle wounds of the chest caused by bullets striking commonly carried military equipment.

BACKGROUND: The purpose of this study was to investigate the fragmentation effect of the bullet that passes through the radio or ammunition magazine, which are essential pieces of equipment for a soldier, in thoracic gunshot injuries. METHODS: Twelve adult pigs were used. The pigs were separated into three groups (each group contained four pigs). The first group was shot without any obstacle between muzzle and subject. The second group was shot through a cartridge magazine placed in front of the subject's thoracic cage. The third group was shot with a radio in front of the subject's thoracic cage. RESULTS: It was observed that there was a large bullet entrance and fragmentation in the pigs that were shot with a radio or magazine placed over them, and there was no fragmentation in those that were shot without any obstacle. CONCLUSION: Metal equipment that soldiers carry causes bullet fragmentation. Fragmented bullets may cause excessive tissue disruption of intrathoracic vital organs.
