사행 폐정맥(meandering pulmonary vein)은 드물게 보이는 폐 혈관 이상으로, 사행성 주행을 보이는 폐정맥이 좌심방으로 배출되는 것을 특징으로 하는 질환이다. 우리는 조영증강흉부 전산화단층촬영 및 폐 혈관 조영술 후 우측 사행 폐정맥으로 진단된 55세 여성 환자를 보고하고자 한다. 조영증강 흉부 전산화단층촬영상 우상폐정맥으로 배출되는 구불구불한 사행성 경로를 보이는 혈관구조물이 우상엽에 있었고, 폐 동정맥 기형이 의심되었다. 진단 및 치료를 위해 폐혈관 조영술이 시행되었고, 폐혈관 조영술에서 먹이 동맥(feeding artery)은 보이지 않았고, 환자는 우측 사행 폐정맥으로 진단되었다. 조영증강 흉부 전산화단층촬영에서 사행 폐정맥과 다른 혈관 기형의 감별이 어려운 경우, 폐혈관 조영술 소견이 진단에 도움이 되며, 추가로 시행할 수 있는 진단도구가 되겠다. 사행 폐정맥의 혈관 조영 소견을 인식함으로써 불필요한 치료가 시행되는 것을 예방할 수 있다.

폐고혈압의 원인은 크게 심박출량의 증가나 혈관 수축 또는 폐쇄에 의한 폐혈관저항의 증가로 볼 수 있고 수동적으로도 높아질 수 있다. 다른 심기형이나 혈관기형을 동반하지 않고 개별 정맥의 협착으로 인해 유발되는 경우는 매우 드물다. 저자들은 출생시 식도 기관루 제거와 식도 연결을 시술한 환아에서 반복되는 청색증과 호흡곤란으로 일반외과 3회 입원 후 식도 협착으로 풍선 확장술을 시행하였던 10개월 영아에서 심초음파를 통해 폐동맥 고혈압을 진단하고 심혈관도자술을 통해 개별 폐정맥들의 협착을 원인으로 밝혔기에 보고하고자 한다.

Arteriovenous malformations (AVMs) are characterized by the presence of abnormal connections between feeding arteries and draining veins. It is generally assumed that symptomatic lesions can preferably be treated. Due to high arterial blood flow, there is a risk of bleeding with surgical excision alone, which can be massive and life threatening during the operation. According to recent advances in interventional technique, a hybrid approach using embolization of the feeding artery with subsequent immediate excision of the AVM for successful management of vascular lesions could be applied to AVMs. Herein, we describe a case of successful excision of AVM in the left soleus muscle using a hybrid approach.

Alveolar soft-part sarcoma(ASPS) is a rare, aggressive malignancy of uncertain histologic origin with a propensity for vascular invasion and distant metastasis. ASPS may mimic benign vascular neoplams of malformation but careful evaluation of the unique imaging features on CT scans, MR images, and angiograms lead to the correct diagnosis. ASPS of the tongue is slow-growing, painless mass, especially ASPS of the base the tongue is difficult to be noticed by patient, dentists or oral and maxillofacial surgeons on oral examintion because of its location and clinical resemblance to a benign lesion. And it leads to delayed or inadequate diagnosis. We report radiologic and clinical features of an ASPS of the basal portion of the tongue in a 17-year-old boy, showing normal appearance, but palpation of the tongue and floor of the mouth reveals the tumor. Among the 23 cases of a primary ASPS of tongue reported, 7 cases occured on the basal region of the tongue, inculding the present one. There has been no recurrence or metastasis as of 3 years postoperatively.

Intraosseous hemangioma is a rare, slow-growing, benign tumor of blood vessels. Primary hemangioma of the skull is a benign lesion that may appear as a palpable mass or accidentally detected during image evaluation. Simple radiography is the most commonly used technique to localize a lesion and computed tomography (CT) may help determine the effect of a lesion. We report a case of multifocal intraosseous calvarial hemangioma developed in the subgaleal plane of an elderly male patient. Ultrasonography examination revealed hyperechoic striated septae parallel to the skin and discontinuity of the focal cortex, however, the underlying bone cortex appeared relatively intact. No significant flow is observed on Doppler ultrasonography. Based on these evaluations, the mass was interpreted by a radiologist as a subgaleal lipoma. This case highlights the importance of additional CT examination in a patient presenting with a scalloping sign of the underlying calvarium. Clinicians also should be aware of the possibility of intraosseous calvarial hemangiomas in lesion. Furthermore, the proper choice of congenital vascular malformation term is still quite confusing with misconception present in the literature.

Background: Treatment for venous malformations of the head and neck includes sclerotherapy, surgical resection, or a combination of both. Surgical resection can remove or reduce the volume of vascular lesions; however, surgery can cause postoperative scarring and potential surgical complications. This study sought to determine the effectiveness of surgery for the treatment of venous malformations of the head and neck. Methods: A retrospective review of the medical records of patients who received surgeries for venous malformations of the head and neck from January 2011 to July 2019 was performed. Using clinical photographs, preoperative and postoperative Doppler ultrasonography, outpatient clinic records, and operation records, the postoperative result and complications were evaluated for each case. Results: Among patients who visited our vascular anomalies clinic, 43 patients (ratio of male to female= 24:19) received surgeries for venous malformations of the head and neck. Twenty-nine patients had undergone surgery only, five patients received sclerotherapy after surgery, and nine patients received surgery after preoperative sclerotherapy. In postoperative evaluations, the result was excellent in 24 patients, good in 18 patients, and poor in one patient. Four patients experienced a recurrence of lesions with lagophthalmos, drooping of the corner of the mouth, partial wound necrosis, and scar widening found in one patient each. Conclusion: Because the head and neck region is the most exposed area in the body, more active implementation of surgical treatments with or without sclerotherapy is essential to reduce the functional and cosmetic impairments associated with venous malformations.

Background The Klippel-Trenaunay syndrome (KTS) is characterized by three clinical features, namely cutaneous capillary malformations, venous malformations, and soft tissue and/or bony hypertrophy of the extremities. The varied manifestations are attributed to the unpredictable clinical nature and prognosis of the syndrome. To elucidate the clinical characteristics of this disease, we reviewed a relatively large number of KTS patients who presented to our vascular anomalies center. Methods We conducted a retrospective study with 19 patients who were diagnosed with KTS and treated in our vascular anomalies clinic between 2003 and 2014, and examined their demographic characteristics, their clinical features, and the treatments administered. Results The sex distribution was balanced, with 9 (47%) males and 10 (53%) females. The mean follow-up period was 4.1 years (range, 7 months-9 years). Most of the patients received conservative treatments such as medication or physiotherapy. Compression therapies such as wearing of elastic garments/bandages were also administered, and surgical interventions were considered only when the patients became excessively symptomatic. Other treatments included laser therapy and sclerotherapy, and all the treatments were adjusted according to each case, tailored to the conditions of the individual patients. Conclusions KTS is an extremely rare, multifactorial disorder that induces widely varied symptoms. Because of this unique feature, plastic surgeons, when not careful, tend to attach a one-sided importance to typical symptoms such as limb hypertrophy or capillary malformation and thus overlook other symptoms and clinical features. KTS can be suspected in all infants who show capillary malformations or limb hypertrophy and require a multi-disciplinary approach for comprehensive management.

Trigeminal neuralgia (TN) is generally characterized by lancinating, unilateral, paroxysmal pain occurring in the distribution of the fifth cranial nerve. TN is diagnosed clinically based on the typical patient history, negative findings in a neurologic examination, and the response to medication. Idiopathic TN is the most common type, but TN can result from vascular malformation, compression, trauma, neoplasm, multiple sclerosis, or inflammation. We report a TN case diagnosed as recurrent trigeminal neuritis of the maxillary branch confirmed by magnetic resonance imaging.

Giant cavernous malformations (GCMs) occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 20-year-old woman with a GCM. She was referred due to two episodes of generalized seizure. Computed tomography and magnetic resonance image demonstrated a heterogeneous multi-cystic lesion of $7\times5\times5$ cm size in the left frontal lobe and basal ganglia, and enhancing vascular structure abutting medial portion of the mass. These fingings suggested a diagnosis of GCM accompanying venous angioma. After left frontal craniotomy, transcortical approach was done. Total removal was accomplished and the postoperative course was uneventful. GCMs do not seem differ clinically, surgically or histopathologically from small cavernous angiomas, but imaging appearance of GCMs may be variable. The clinical, radiological feature and management of GCMs are described based on pertinent literature review.
