  • The vasodilatory shock after cardiopulmonary bypass is defined as the condition involving severe and persistent form of hypotension, tachycardia, normal or increased cardiac output and decreased systemic vascular resistance. Because of the unsuccessful response to infusion of fluids or catecholamine vasopressors, a sustained systemic shock state occurs and results in a high morbidity and mortality. We successfully treated this syndrome of 3 patients after open heart surgery with low dose of arginine vasopressin(AVP). Therefore, we report these cases with a review of related articles.

  • A 3-month-old male, Cocker Spaniel with persistent regurgitation immediately after weaning and stunted growth was referred. Radiographic findings on the lateral view include ventral deviation of the thoracic trachea caused by draping of the dilated esophagus and a distinct interface of the dorsal wall of the esophagus silhouetting with the cranial thoracic hypaxial muscles. On the ventrodorsal view, the cranial mediastinum was widened with soft tissue opacity. The trachea was deviated to the right. In an esophagogram, the segmental dilation of the esophagus with constriction of the lumen just cranial to the heart base was identified. In a fluoroscopic examination, the contrast medium was massively accumulated in the cranial portion of the constricted esophagus. At surgery, it was confirmed that the esophageal tract was constricted at the cranial to the base of the heart by aberrant right subclavian artery. It was ligated and divided surgically. Current state of the referred is maintained normal condition from the surgical repair.

  • Background: Some of head and neck cancer patients are in compromised general condition after ablation surgery and chemoradiation therapy, which makes secondary free tissue transfer quite challenging. Elderly cancer patients also have some risk for microvascular surgery with lengthened general anesthesia. In those cases, the pedicled flap vascularized by supraclavicular artery could be considered as an alternative to free flap. Despite several authors have demonstrated the clinical reliability of supraclavicular artery island flap (SCAIF), to date, SCAIF has not been widely used among reconstructive surgeon. In this article, we clarified vascular flow pattern and introduce simple surgical technique of SCAIF with a literature review. Case presentation: Three patients who had underwent previous neck surgery and adjuvant therapy received maxillofacial reconstruction using SCAIF. It required only a few landmarks, flap harvesting was carried out, and the elapsed time gradually decreased to 15 min with experiences. There were no remarkable morbidities in both donor and recipient sites. Conclusion: SCAIF exhibited minimal anatomic variations and short learning curve of surgical techniques, which might be valuable reconstruction modality for beginning surgeon. And it can be beneficial option for the patients with vessel-depleted neck, medically compromised status for lengthened general anesthesia and failed free tissue transfer.

  • The results obtained from te field investigations of Chuja Island conducted for 5 days from July 18 to 22, 1980 and from August 12 to 16, 1981 are summarized as follows: Vascular plants of this island disclosed by the present study consisted of 86 families, 210 genera, 228 species, 38 varieties and 4 래금. Nineteen species of evergreen broad-leaved trees were discovered, including Litsea japonica Juss, Camellia japonica L. and Machilus thunbergii Sieb. et Zucc. These indeciduous latifoliate trees were preserved in poor condition. Ten-twenty years old Pinus thunbergii was confirmed to be the predominant species. Seaside plants encountered were 6 species, including Vitex rotundifolia L. Fil. and Asterspathullfoius Max., but they were poorly distributed. Naturalized plants comprised a total of 12 species. This varied number of species is considered attributable to the frequent access of men owing to convenient marine traffic. the destruction of vegetation of this island may be attributed to human interference (loggin for boat construction, building and charcoal materials) ever escalated by high population density. It is worthy of noting that Bochmeria penosa Nakai et Stake which forms a large community in this island can be used as textile resources.

  • The characteristics of extra-nasopharyngeal angiofibromas tend to be different from angiofibromas of the nasopharynx according to patient gender, patient age, prevalence, affected site, pathogenesis, and clinical and epidemiological features. We report a case of an extra-nasopharyngeal angiofibroma in a 28-year-old man referred to the ENT Clinic for right-sided epistaxis, airflow impairment and nasal swelling. The right nostril was completely occluded works by a reddish-yellow mass that bled easily. The computed tomography scan revealed an "inhomogeneous solid lesion in the nasal fossa". With the patient under general anesthesia, the formation in the anterior portion of the right side of the nasal septum was removed up to its vascular base. Although electrical cauterization efficiently controlled the bleeding, we abraded the sub-perichondral area to prevent further bleeding as well as recurrence. The histological exam report confirmed the diagnosis of angiofibroma. As in our case, epistaxis is commonly the presenting sign of angiofibroma. Yet its onset was peculiar, given that the bleeding started with a low impact trauma. The nasal swelling was also a relevant feature as well as the breathing impairment. Although uncommon, nasal septal angiofibromas should considered in patients with epistaxis.

  • Ehlers-Danlos syndrome (EDS) VIII is an autosomal dominant inherited connective tissue disorder characterized by intractable periodontal inflammation, absence of gingiva, pretibial plaques, skin hyperextensibility, joint hypermobility, and tissue fragility with onset in the childhood or adolescence. In a recent report, heterozygous variants of the C1R or C1S related to the classical complement pathway were identified in families with history of EDS VIII. The current report describes a Korean 34-year-old female carrying a novel missense variant of C1R c.925T>G (p.Cys309Gly) and exhibiting early severe periodontitis, skin fragility, and joint hypermobility. The patient also had frontal, parietal, and temporal white matter brain lesions without definite vascular abnormalities on brain magnetic resonance imaging, which have not been surveyed meticulously in EDS VIII. Considering the genetic alteration of classic complement pathways in this condition, it is necessary to carefully observe multisystemic inflammation processes such as changes in brain white matter.

  • Infantile osteomyelitis is a rare disease that is infective in nature and may rapidly turn fatal, as the disease is often misdiagnosed due to its varied presenting signs. Early diagnosis may help in avoiding systemic involvement and permanent deformity. The disease presents with signs of orbital involvement, nasal congestion, and emesis, as well as other standard hallmarks of infection. Furthermore, the maxilla is a highly vascular and porous bone and the occurrence of osteomyelitis in an infant maxilla is highly uncommon. In addition, routine blood work is not suggestive of the presence of this disease. Thus, prompt diagnosis of this condition poses a challenge to surgeons due to the confusing array of symptoms combined with the rarity of the disease. One such case of osteomyelitis of the maxilla in a young child is presented. The dilemma encountered by the surgeon during the diagnosis and treatment of the disease is discussed.

  • This study used a adult absorption dose phantom (CIRS model 701-G, USA) made of human equivalent material and the vascular imaging equipment Allura Xper FD 20 (Philips, Netherlands). Optically stimulated luminescent dosimeters (OSLD) were inserted into the anatomical positions corresponding to each organ, and the exposure dose was measured. Dose area product (DAP) and air kerma (AK) measured by the dose meter in the equipment were compared. Continuous imaging was performed at two angles for a total of 20 minutes, with a frame per seconds of 3.75 and 7.5 fps and an FOV of 42 cm, 37 cm, and 31 cm, respectively, under the conditions of fluoflavor I, II, and III, each selected for 5 repetitions. This study was found that selecting a lower fps was the most effective way to reduce patient exposure dose, and adjusting the fluoflavor was a good alternative method for reducing patient exposure dose at high fps. Therefore the method of condition change with the greatest dose reduction effect is to set the minimum FPS and can reduce patient exposure dose according to geometric conditions and fluoflavor characteristics.

  • Dural arteriovenous fistula (DAVF) is a rare condition affecting approximately 1.5% of 1,000,000 individuals annually. It frequently occurs in the transsigmoid and cavernous sinuses. An isolated sigmoid sinus is extremely rare and is treated by performing transfemoral transvenous embolization along the opposite transverse sinus. A 69-year-old woman presented with asymptomatic Borden type III/Cognard type III DAVF involving an isolated sigmoid sinus. She underwent a staged operation in which a navigation system was used to expose the sigmoid sinus in the operating room before transferring the patient to the angio suite for transvenous embolization. Various modalities have been used to treat DAVF, including surgical disconnection, transarterial embolization, transvenous embolization, and stereotactic radiosurgery. However, treating DAVF cases where the affected sinus is isolated can be challenging because an easily accessible surgical route may not be available. In this case, direct sinus cannulation and transvenous embolization were the most effective treatments.
