采用考查右肺上叶和中叶的方法考查了50例成年右肺下叶的支气管和血管。右下叶恒定的段支气管有五支,即尖段支气管(B~6),内侧基底段支气管(B~7),前基底段支气管(B~8),外侧基底段支气管(B~9),后基底段支气管(B~(10))。尖下段支气管(B~*)的出现率为46%。B~6最常见的分支型式是单干类二分支型(B~6c,B~6a+b),为84%。B~7的内侧支(B~7b)经右下肺静脉后方(深面)分布于椎旁面的为10%,在施行内侧基底段切除时应予注意,以免损伤右下肺静脉。外侧基底段支气管的后支(即BX~*a)在右下叶的出现率为12%。本文讨论了BX~*(10)和BX~*(9)的命名问题。右下叶动脉的分支数目和分支型式与支气管相同的仅为14%,彼此数目相同分支型式不同的为26%,其余动脉的分支数目和分支型式均不一致。尖段动脉(A~6)的常见分支型式与尖段支气管一样,是单干类的二分支型(A~6c,A~6a+b),为58%。前基底段动脉(A~8)与内侧基底段动脉(A~7)或内侧基底段动脉外侧支(A~7a)共干的占48%,与其它作者的结果之间有显著差别。尖下段动脉(A~*)的来源不一,它的总支数较B~*多,除A~*与同数的B~*伴行外,还有三支A~*伴两支B~*的现象。后基底段动脉后支(A~(10)c)(即AX~*(10))的起源和支数与尖下段动脉有相似的现象。尖下段动脉和后基底段动脉的后支与它们所伴行的支气管之间,在起源上和分支数目上存在着异源异数或异源同数或同源异数的关系。右肺下叶的静脉与右上叶和中叶一样,行于段间或亚段间,汇集成尖段静脉、上基底静脉和下基底静脉三大支。上、下基底静脉先汇集成总基底静脉,再与尖段静脉组成右下肺静脉。上基底静脉和下基底静脉的组成型式,本文分为正常型、分裂型和异常型。正常型是常见的型式,为66%。右肺下叶的静脉与支气管和动脉间缺少联系。动脉与支气管在分支型式上不尽相同,但在分布上却紧密伴随。
Using the method of examining the upper lobe and middle lobe of the right lung, bronchial and blood vessels were examined in 50 patients with lower right lung. The right lower lobe of the constant segment of the bronchus has five, namely, the sharp segment of the bronchus (B ~ 6), the medial basal segment of the bronchus (B ~ 7), the anterior basal segment of the bronchus (B ~ 8) , Basal segment of the bronchus (B ~ (10)). The next lower extremity bronchus (B ~ *) was 46%. The most common branch pattern of B ~ 6 is the simplex type (B ~ 6c, B ~ 6a + b), which is 84%. The medial branch (B ~ 7b) of B ~ 7 is distributed 10% behind the paraspinal side of the right lower pulmonary vein (deep surface). Care should be taken when removing the medial basal segment to avoid damaging the right lower pulmonary vein. Lateral branch of the basal segment of the bronchial branch (ie, BX ~ * a) in the lower right lobe of the incidence of 12%. This article discusses the naming of BX ~ * (10) and BX ~ * (9). The number and branch pattern of the right lower lobe artery was the same as that of the bronchus only 14%, while the number of branches of the same branch pattern was 26%. The number of branches and branches of the other arteries were different. The common branches of the apical arteries (A ~ 6), like the apical segments of the bronchus, are bifidus type (A ~ 6c, A ~ 6a + b) of 58%. There was a significant difference between the results of the previous study (48%) of the anterior basilar artery (A ~ 8) and the medial basal segment artery (A ~ 7) or the medial basilar artery lateral branch (A ~ 7a) The lower extremity arteries (A ~ *) have different origins, and their total number is more than B ~ *. In addition to A ~ * with the same number of B ~ *, there are three A ~ * with two B * The phenomenon. The posterior branch of the basilar artery (A ~ (10) c) (ie, AX ~ * (10)) has similarities in origin and number to the inferior cusp artery. There is a heterogeneous number of heterologous or heterologous homogonous or homologous numbers in the origin and number of branches between the posterior branches of the inferior and inferior basilar arteries and the bronchi they accompany. The right lower lobe of the vein and the right upper lobe and middle leaves, as in the inter-segment or sub-segment, converged into a segment of veins, the upper basal vein and the lower basilar vein three branches. The upper and lower basilar veins are first aggregated into total basilar veins and then the lower veins are formed with the tip veins. Upper basilar veins and the composition of the lower basilar veins, this article is divided into normal type, split type and abnormal type. Normal type is the common type, 66%. The lower right pulmonary vein has little contact with the bronchi and arteries. Arteries and bronchi in the branch type is not the same, but in the distribution are closely associated.
