RESUMEN

OBJECTIVE: To investigate and compare the diagnostic values of bronchoscopy and multi-slice spiral computed tomography (CT) for congenital dysplasia of the respiratory system in infants. METHODS: Analysis was performed on the clinical data, bronchoscopic findings and multi-slice spiral CT findings of 319 infants (≤1 years old) who underwent bronchoscopy and/or multi-slice spiral CT and were diagnosed with congenital dysplasia of the respiratory system. RESULTS: A total of 476 cases of congenital dysplasia of the respiratory system were found in the 319 infants, including primary dysplasia of the respiratory system (392 cases) and compressive dysplasia of the respiratory system (84 cases). Of the 392 cases of primary dysplasia of the respiratory system, 225 (57.4%) were diagnosed by bronchoscopy versus 167 (42.6%) by multi-slice spiral CT. There were significant differences in etiological diagnosis between bronchoscopy and multi-slice spiral CT in infants with congenital dysplasia of the respiratory system (P<0.05). All 76 cases of primary dysplasia of the respiratory system caused by tracheobronchomalacia were diagnosed by bronchoscopy and all 17 cases of primary dysplasia of the respiratory system caused by lung tissue dysplasia were diagnosed by multi-slice spiral CT. Of the 84 cases of compressive dysplasia of the respiratory system, 74 cases were diagnosed by multi-slice spiral CT and only 10 cases were diagnosed by bronchoscopy. CONCLUSIONS: Compared with multi-slice spiral CT, bronchoscopy can detect primary dysplasia of the respiratory system more directly. Bronchoscopy is valuable in the confirmed diagnosis of tracheobronchomalacia. Multi-slice spiral CT has a higher diagnostic value for lung tissue dysplasia than bronchoscopy.

RESUMEN

PURPOSE: The aim of this study was to provide some important information about the morphology and topography of the recurrent laryngeal nerve (RLN) and inferior thyroid artery (ITA), which significantly helps localize and protect the RLN in neck surgery, especially in thyroid surgery. METHODS: Eighty adult cadavers (160 sides) fixed with formalin were dissected, analyzed and measured. RESULTS: (1) 87.5% of the RLNs gave off multiple branches like a tree; the incidence of the RLN loop, connecting one branch to another was 3.125%; in 9.375%, one branch of RLN combined with cervical sympathetic chain (CSC) or superior laryngeal nerve (SLN). (2) A double RLN appeared in four sides, a non-recurrent inferior laryngeal nerve appeared in two cases. (3) In two cases, the RLN communicated with both of the SLN and the CSC near thyroid gland. (4) Most of the ITAs was derived from thyrocervical trunk, and divided into two or three branches before entering the thyroid gland. (5) Three ITAs gave off esophageal branch, one ITA gave off tracheal branch, one right ITA originated abnormally. (6) On the left side, the RLN was behind the ITA in 86.25% of the cases, in front of the artery in 7.5%, the nerve was between artery branches in 2.5%, the artery was between nerve branches in 1.25%, and was among the combined in 2.5%. On the right side, the RLN was in front of the artery in 75.0%, behind the artery in 10.0%, among the branches of the artery in 5.0%, 10.0% the branches of both nerves and artery were interlaced that the relationship between the branches of the nerve and the artery was uncertain. CONCLUSIONS: Because of the variability of the RLN and ITA and the complicated relationship between them, it is necessary to dissect and recognize the RLN to avoid mistaking, ignoring, and misligating of the nerve before ligating the ITA.
