Systemic arterialization of lung with/without sequestration (Sequestration/Anomalous Origin of Left Pulmonary Artery, AOLPA) is a rare form of congenital anomalous systemic arterial supply to the lungs. In this anomaly, the arterial supply of one or more arteries of the basal segments of the lower lobe derives from an aberrant vessel arising from the aorta. We report two adult cases of systemic arterialization of normal basal segments of left lower lobe lung with/without sequestration. The one (AOLPA) was treated by left lower basal segmentectomy and the other (Sequestration) by therapeutic angiographic embolization. Based on the favorable follow-up result in our patients, although lobectomy (segmentectomy) is the basic treatment modality, embolotherapy could also be a mode of treatment that could be selectively applied to elderly, infirm patients or high risk patients with poor pulmonary function.

Background: This study investigated the distribution of valve incompetence in patients with chronic venous disease (CVD) and its correlation with the clinical category of the clinical, etiological, anatomical, and pathophysiological (CEAP) classification. Methods: In total, 1,386 limbs with clinically suspected CVD were categorized according to the CEAP classification and consecutively underwent duplex ultrasonography between April 2017 and December 2020. Results: There were 362 limbs in male patients and 1,024 limbs in female patients. The limbs were classified as C0s-C1 (608 limbs, 43.8%), C2 (727 limbs, 52.5%), or C3-C6 (51 limbs, 3.7%). The prevalence of saphenous vein incompetence in CEAP C0s-C1 limbs was 43.6%. The saphenofemoral junction (SFJ) was competent in 37% of CEAP C2-C6 limbs. The CEAP C3-C6 category was not correlated with reflux patterns of the saphenous vein system (Cramer's V=0.07), incompetent SFJ (Cramer's V=0.07), deep vein reflux (Cramer's V=0.03), or the distribution of incompetent segments in the great saphenous vein (GSV) (Cramer's V=0.11). Conclusion: Duplex ultrasonography is necessary to formulate a proper treatment plan for limbs categorized as CEAP C0s-C1. The SFJ was competent in more than one-third of CEAP C2-C6 limbs with GSV reflux; as such, flush ligation of the GSV may be unnecessary in these patients. The CEAP C3-C6 category showed no correlations with reflux patterns of the saphenous vein system, SFJ reflux, deep vein reflux, or the distribution of incompetent segments in the GSV.

Objectives : There are many theories about the anatomical relationships between the thoracic spinous and transverse processes. However, these studies were all conducted on cadavers. Thus, there might be differences when applied to living individuals. Therefore, the aim of this study was to determine whether the theories were similar when measured in living individuals. Methods : We conducted studies with 10 individuals aged 20-30 using 3D-CT. Four different measurements were taken between the thoracic spinous and transverse processes. To facilitate the relationship analysis, the spinous process positioned between the traverse process of the segment and the lower segment was set to 0.5. The spinous process located at the height of the traverse process of the lower segment was set to 1. The spinous process located between the traverse process of the lower segment and the two segments below was set to 1.5. Results : Therefore, based on the aforementioned settings, T1-T4 were 1, T5-T7 were 1.5, T8-T10 were 1, and T11 and T12 were 0.5. This indicated that the spinous processes of T1-T4 and T8-T10 were equal in height to the transverse processes of the lower segment, and that T5-T7 were at the midpoint of the height of the transverse processes between the lower segment and two segments below, and T11, T12 corresponded to the midpoint between the traverse process of the segment and the lower segment. Conclusions : Neither 'Geelhoed's rule'nor 'the rule of three'was accurate when applied to living individuals. However, this study had some limitations, so further research is needed.

Objective : To characterize perioperative biomechanical changes after thoracic spine surgery. Methods : Fifty-eight patients underwent spinal instrumented fusions and simple laminectomies on the thoracolumbar spine from April 2003 to October 2008. Patients were allocated to three groups; namely, the laminectomy without fusion group (group I, n = 17), the thoracolumbar fusion group (group II, n = 27), and the thoracic spine fusion group (group III, n = 14). Sagittal (ADS) and coronal (ADC) angles for adjacent segments were measured from two disc spaces above lesions at the upper margins, to two disc spaces below lesions at the lower margins. Sagittal (TLS) and coronal (TLC) angles of the thoracolumbar junction were measured from the lower margin of the 11th thoracic vertebra body to the upper margin of the 2nd lumbar vertebra body on plane radiographs. Adjacent segment disc heights and disc signal changes were determined using simple spinal examinations and by magnetic resonance imaging. Clinical outcome indices were determined using a visual analog scale. Results : The three groups demonstrated statistically significant differences in terms of angle changes by ANOVA (p<0.05). All angles in group I showed significantly smaller angles changes than in groups II and III by Turkey's multiple comparison analysis. Coronal Cobb's angles of the thoracolumbar spine (TLC) were not significantly different in the three groups. Conclusion : Postoperative sagittal balance is expected to change in the adjacent and thoracolumbar areas after thoracic spine fusion. However, its prevalence seems to be higher when the thoracolumbar spine is included in instrumented fusion.

The purpose of this morphological studies was to investigate the central neural pathway projecting to the acupoints $B_{62}$ and $K_6$ using the neuroanatomical method following injection of transsynaptic neurotropic virus, pseudorabies virus(PRV-Ba and PRV-Ga) into the $B_{62}$ and $K_6$. After survival times of 96 hours following injection into the twenty rats with PRV-Ba(Bartha strain) and PRV-Ga(Bartha strain, ${\beta}$-galacidodase insertion). They were perfused, and their spinal cord and brain were frozen sectioned($30{\mu}m$). These sections were stained by X-gal histochemical and PRV immunohistochemical staining method, and observed with light microscope. The results were as follows : 1. In spinal cord, overlaped PRV-Ba and PRV-Ga labeled neurons projecting to the $B_{62}$ and $K_6$ were founded in thoracic, lumbar and sacral spinal segments. In thoracic spinal segments, Densely labeled areas were founded in lamina IV, V, VII(intermediolateral nucleus) and X areas. In lumbar segemnts, labeled areas were founded in lamina II, IV, V and X areas. In sacral spinal segments, labeled areas were founded in lamina IV, V and VI areas. 2. In brain, overlaped PRV-Ba and PRV-Ga labeled neurons projecting to the $B_{62}$ and $K_6$ were founded in the $A_1$ noradrenalin cells/$C_1$ adrenalin cells/caudoventrolateral reticular nucleus, rostroventrolateral reticular nuclens, nucleus tractus solitarius, area postrema, raphe obscurus nucleus, raphe paltidus nucleus, raphe magnus nucleus, lateral paragigantoceltular nucleus, lateral rcticular nucleus, gigantocellular nucleus, locus coeruleus, subcoeruleus nucleus, motor trigeminal nucleus, Kolliker-Fuse nucleus, $A_5$ cell group, central gray matter, oculomotor nerve, paraventricular hypothalamic nucleus, median eminence, amygdaloid nucleus, frontal cortex, forelimb area, hindlimb area, 1, 2 areas of parietal cortex and granular and agranular cortex. This results were suggest that overlaped PRV-Ba and PRV-Ga labeled areas projecting to the $B_{62}$ and $K_6$ may be related to the emotional relay pathway in the central autonomic center.

Background: Calcific degeneration is the major cause of clinical failure of glutaraldehyde (GA) crosslinked bioprosthetic tissues implanted in the body and necessitates the reoperation or causes death. Surface modification of biologic tissues using sulfonated polyethyleneoixde (PEO-SO3) has been suggested to significantly enhance blood compatibility, biostability and calcification-resistance by means of the synergistic effect of highly mobile and hydrophilic PEO chains and electrical repulsion of negatively charged sulfonate groups. This study was designed to evaluate the anticalcification effect of surface-modification of biologic arteries by direct coupling of PEO-SO3 after GA fixation and changes of calcification according to the implantation period through the quantitative investigation of the deposited calcium and phosphorous contents of the biologic arterial tissues in the canine circulatory implantation model. Material and Method: Total of 16 fresh canine carotid arteries were harvested from eight adult dogs and divided in to GA group(n =8) and PEO-SO3 group(n=8). Sulfonation of diamino-terminated PEO was performed using propane sultone. Canine carotid arteries were only crosslinked with 0.65% GA solution in GA group and modified by direct coupling 5% PEO-SO3 solution after GA crosslinkage for 2 days and stabilized by NaBH4 solution for 16 hours in PEO-SO3 group. In both groups the resected segment of bilateral carotid arteries were reconstructed. Reconstructed segments of the two groups were analysed the quantities of calcium and phosphorous contents after 3(n=4) and 6(n=4) weeks in vivo. Result: After implantation of 3 seeks, PEO-SO3 group showed significantly less depositions.

Two cases of an anomalous systemic arterial supply to the basal segments of the left lower lobe without pulmonary sequestration are presented. In the first case, a preoperative diagnosis was made by chest CT, and confirmed by angiography, in a 22-year old man who had a recurrent hemoptysis. There was systemic arterial supply that originated from the thoracic descending aorta and no pulmonary arterial supply to the basilar segments of the left lower lobe. However, the pulmonary parenchyma was normal without sequestration. Ligation of the abnormal artery and a left lower lobectomy were performed without complications. In the second case, there were characteristic features of this anomaly on chest CT and the angiogram in a 31-year-old man with symptoms of hemoptysis. The patient refused surgery.

Though myocardial perfusion was usually expected to improve after coronary artery bypass graft(CABG) surgery, some myocardial segments were aggravated after operation, as we compared perfusion changes on postoperative SPECT with preoperative ones. In this study, we evaluated perfusion changes after operation in rest and stress myocardial SPECT in 44 patients (M:F=25:19, age 57.1 $year{\pm}8.2$) who had CABG before and 3 months after operation. We tried to find out possible causes for perfusion aggravation with multivariate logistic regression analysis regarding whether bypass graft was artery or vein and which coronary artery territory was operated. Among 616 myocardial segments which were operated, 89(14.4%) aggravated after operation. In the univariate analysis, myocardial segments in the left circumflex arteries(LCx) aggravated more often(p<0.01) than others and segments having operative angioplasty did less often(p<0.01). Multivariate logistic regression revealed that LCx was risk factor for perfusion aggravation [odds ratio=2.54 (95% confidence interval : 1.53-4.22, p<0.01)]. However, this was not the case when we analysed in terms of arterial territories. Among 106 coronary arterial territories which were operated, 27(25.5%) aggravated. The territories having aggravated had similar characteristics regarding whether they received arterial or venous grafts, angioplasty and whether the operated territories were left anterior descending, right coronary or left circumflex arteries. In conclusion, myocardial segments in the left circumflex artery tended to aggravate more often after bypass surgery than the others. In short-term comparison of perfusion after surgery, we could not find any tendency that arterial or venous graft was associated with more frequency of the aggravation of perfusion after operation.

Objectives : Hua-Tuo-Jia-Ji-Xue(華佗夾脊穴) is the Jing-Wai-Qi-Xue(經外奇穴) that is widely used in clinic and effective in Acupuncture and Moxibustion. But the location, number, acupuncture method, clinical application of Hua-Tuo-Jia-Ji-Xue have not been explained clearly and consistently; moreover, studies or clinical reports about this are insufficient. The purpose of this study is to investigate the location, number, acupuncture method, clinical apptication of Hua-Tuo-Jia-Ji-Xue. Methods : We investigated Hua-Tuo-Jia-Ji-Xue through survey of 11 books and 26 relevant journals published in China Results : 1. Hua-Tuo-Jia-Ji-Xue is located in about 0.5 Cun(寸) at both sides of spinous process of each vertebra. 2. There is differ as the number of Hua-Tuo-Jia-Ji-Xue is 34, 48, 56, 58 in each documents. Hua-Tuo-Jia-Ji-Xue located in first, second cervical vertebra and first sacrum is low in application frequency, Hua-Tuo-Jia-Ji-Xue located from third cervical vertebra to fourth lumbar vertebra is high in apptication frequency. Therefore, all of the acupoints located in about 0.5 Cun(寸) both sides of spinous process of cervical, thoracic, lumbar and sacral vertebrae are regarded as Hua-Tuo-Jia-Ji-Xue in wide meaning. 3. There are Kou-Ci-Fa(叩刺法), Qian-Ci-Fa(淺刺法), Yan-Pi-Ci-Fa(沿皮刺法), Shen-Ci-Fa(深刺法) in acupuncture method of Hua-Tuo-Jia-Ji-Xue. Acupuncturing depths, directions is differ in each location(cervical, thoracic, lumbar vertebra, sacrum) and have something to do with therapeutic effect of Hua-Tuo-Jia-Ji-Xue. The feeling that patient receive after acupuncture is the key to the treatment of disease. 4. The clinical application of each Hua-Tuo-Jia-Ji-Xue is mainly selected by distribution of meridians, nerve roots, vertebral segments which are attacked with a disease. The musculoskeletal diseases in treatment of disease by Hua-Tuo-Jia-Ji-Xue are the most common as 12 cases. Second, there are many reports about nervous system diseases. In addition, good therapeutic results by application of Hua-Tuo-Jia-Ji-Xue are reported in some diseases, for instance, diseases of five viscera and six entrails, organ, tissue Conclusions : Hua-Tuo-Jia-Ji-Xue is located in about 0.5 Cun(寸) at both sides of spinous process of each cervical, thoracic lumbar and sacral vertebra. Therapeutic effect of Hua-Tuo-Jia-Ji-Xue has something to do with acupuncturing depths, directions and feelings. Hua-Tuo-Jia-Ji-Xue is mainly selected by distribution of meridians, nerve roots, vertebral segments which are attacked with a disease and is mainly applied musculoskeletal diseases, nervous system diseases.

Between 1967 and 1980, a total of 99 patients with a benign stricture of esophagus, resulting from a chemical burn, underwent a reconstructive procedure in which various segments of colon were used to bridge the gap between the cervical esophagus and the stomach. There were 42 males and 57 females and most were in their twenties and thirties. The most frequent site of the stricture was upper 1/3 of the thoracic esophagus [48.5%] and the next most common site was the low cervical esophagus [23.2%]. In 89 cases, the right colon with or without the terminal ileum was used as the conduit in an isoperistaltic manner and in 10, the left colon was used in an antiperistaltic position, because the right colon was not suitable as the conduit. There was a higher incidence of regurgitation [90% vs 0%], leakage at cervical anastomosis [80% vs 27%] and stenosis at anastomotic site [70% vs 15%] in an antiperistaltic left colon anastomosis, as compared to isoperistaltic right colon anastomosis. This was felt to be due to the orad peristaltic motion of the transplanted colon which acted as a functional obstruction distal to the esophagocolic suture line, resulting in breakdown of the anastomosis, leakage and eventual stenosis at the site of anastomosis. In conclusion, colon is useful and effective conduit as an esophageal substitute. Either the right or the left colon can be used for this purpose, provided that it is placed in an isoperistaltic position to minimize some of the complications listed above.
