  • Objective: To describe the neuroradiologic findings of primary antiphospholipid antibody syndrome (PAPS). Materials and Methods: During a recent two-year period, abnormally elevated antiphospholipid antibodies were detected in a total of 751 patients. In any cases in which risk factors for stroke were detected - hypertension, diabetes mellitus, hyperlipidemia, smoking, and the presence of SLE or other connective tissue diseases - PAPS was not diagnosed. Neuroradiologic studies were performed in 11 of 32 patients with PAPS. We retrospectively reviewed brain CT (n = 7), MR (n = 8), and cerebral angiography (n = 8) in 11 patients with special attention to the presence of brain parenchymal lesions and cerebral arterial or venous abnormalities. Results: CT or MR findings of PAPS included nonspecific multiple hyper-intensity foci in deep white matter on T2-weighted images (5/11), a large infarct in the territory of the middle cerebral artery (4/11), diffuse cortical atrophy (2/11), focal hemorrhage (2/11), and dural sinus thrombosis (1/11). Angiographic findings were normal (5/8) or reflected either occlusion of a large cerebral artery (2/8) or dural sinus thrombosis (1/8). Conclusion: Neuroradiologic findings of PAPS are nonspecific but in young or middle- aged adults who show the above mentioned CT or MR findings, and in whom risk factors for stroke are not present, the condition should be suspected.

  • Central venous catheterization through a subclavian approach is indicated for some special purposes but it may cause many complications such as infection, bleeding, pneumothorax, thrombosis, air embolization, arrhythmia, myocardial perforation, and nerve injury. A case involving a mistaken central venous catheterization into the right vertebral artery through the subclavian artery is presented. A 33-year-old man who had deteriorated mentality after head injury underwent an emergency craniotomy for acute epidural hematomas on the right frontal and temporal convexities. His mentality improved rapidly, but he complained of continuous severe pain in the right posterior neck even though he had no previous symptom or past medical history of such pain. Three-dimensional cervical spine computed tomography (3D-CT) was performed first to rule out unconfirmed cervical injuries and it revealed a linear radiopaque material intrathoracically from the level of the 1st rib up to the level of C6 in the right vertebral foramen. An additional neck CT was performed, and the subclavian catheter was indwelling in the right vertebral artery through right subclavian artery. For the purpose of proper fluid infusion and central venous pressure monitoring, the subclavian vein catheterization had been performed in the operation room after general anesthesia induction before the craniotomy. Sufficient anatomical consideration and prudence is essential because inadvertent arterial cannulation at a non-compressible site is a highly risky iatrogenic complication of central venous line placement.

  • Background: A sians were known to have a relatively lower incidence of venous thromboembolism (VTE), and there is insufficient evidence to suggest a specific D-dimer threshold level for screening VTE in patients with acute stroke. Methods: We prospectively enrolled patients with acute ischemic stroke admitted to Jeju National University Hospital. The inclusion criteria were: 1) aged ${\geq}18$ years, 2) admission within seven days of symptom onset, and 3) an initial National Institute of Health Stroke Scale (NIHSS) score >1 for the affected lower limb. Ultrasound scans of the lower limbs and plasma D-dimer assays were performed on days 7-14 and 15-28 after stroke onset. Results: Of 285 patients admitted during the study period, 52 patients met inclusion criteria (mean age 74.5, male 40.4%, median initial NIHSS score 12, and unable to walk unassisted at discharge 76.9%). During 7-14 days, 23 of 52 patients (44.2%) had a D-dimer level above 1.57 mg/L, and 9.6% had a level above 5.50 mg/L. Proximal deep vein thrombosis (DVT) was detected in 3 patients (5.8%, 95% confidence Interval 1.2-16.0%) on ultrasound examination. All DVTs were found in elderly female patients with severe leg weakness. No patient was diagnosed with pulmonary embolism during the study period. Conclusion: The incidence of VTE seems to be very low among Korean patients with acute ischemic stroke. Advanced age, female sex, and severe leg weakness were important risk factors for developing DVT in this study.

  • 배경: May-Thurner 증후군은 좌측장골정맥이 우측장골동맥에 의해 눌리어 정맥 환류장해에 의해 혈전증을 일으키는 것을 말한다. 저자들은 심부 정맥혈전중의 치료를 위해 시행한 혈전 제거-용해술 및 스탠트 삽입술의 결과를 분석하고자 한다. 대상 및 방법: May-Thurner 증후군과 동반된 하지 심부정맥혈전증으로 진단받고 좌측 장골정맥에 스탠트를 삽입한 34명(평균연령 $64.6{\pm}13.7$세, 여자 25(74%)명)을 대상으로 하였다. 시술은 흡인성 혈전제거와 혈전용해 후 분지성 협착이 있는 곳에 Wall stent를 삽입하고 풍선 확장을 하였다. Multi side hole 카테타를 혈전이 있는 부위에 위치시키고 Urokinase를 시간당 8만에서 12만 International Unit을 1일 또는 2일 동안 주입하였다. 시술 중 폐동맥혈전색전증을 방지 하기 위하여 대부분 환자에서 시술 전 일시적 하대정맥 여과기(IVC Filter)를 삽입하였다. 퇴원 후 3개월간 경구용 와파린을 투여 하였으며 퇴원 전과 퇴원 후 6개월에 Multi Detector Computerized Tomography (MDCT) 혈관촬영을 이용하여 혈전의 유무를 판단하였다. 결과: 시술 48시간 이내 부종과 동통이 완전하게 소실된 환자가 2 (6%)명이었으며 증상의 완화가 있는 환자가 28 (82%)명, 증상의 호전이 없는 환자가 4 (12%)명이었다. 퇴원 시 MDCT혈관촬영에서 9 (26%)명에서 혈전없음, 21 (62%)명에서 부분 혈전, 그리고 4명(12%)에서 폐쇄소견을 보였다. 퇴원 6개월 후에 2명을 제외한 32명이 추적 MDCT혈관촬영을 하였는데 23 (72%)명에서 혈전없음을 9 (26%)명에서는 부분혈전이 관찰 되었다. 평균 5.6개월 관찰기간 동안 2 (6%)명에서 심부정맥혈전이 재발되어 재입원하였으며 하지 부종과 통증을 동반한 혈전 후 증후군은 9예(26%)에서 발생하였다. 결론: May-Thurner 증후군과 동반된 하지 심부정맥혈전환자에서 심부정맥혈전의 제거와 혈전용해술과 함께 시술된 스탠트 삽입은 효과적인 치료 방법으로 생각된다.

  • Purpose: The main cause of flap loss in microsurgical tissue transfer is venous insufficiency. Whether or not multiple venous anastomoses prevents vascular thrombosis and reduces the risk of flap failure remains controversial. Some researchers are in favor of performing dual venous anastomoses, but the counterargument holds that performing a single venous anastomosis does provide advantages. Materials and Methods: We carried out a retrospective analysis of 15 cases of anterolateral thigh free flap for extremity reconstruction performed between January 2011 and December 2013. The patients were categorized into two groups: group A that received a single venous anastomosis and group B that received dual venous anastomoses. The time of the anastomosis, size of the flap, complications of the flap, and survival rate of each group were analyzed. Results: The total microsurgical time in the single venous anastomosis group ranged from 28 to 43 minutes (mean 35.9 minutes). The total time in the dual anastomoses group ranged from 50 to 64 minutes (mean 55.7 minutes). No statistically significant difference was found between the two groups with regards to postoperative complications and flap failure. Conclusion: Our study suggests that the use of a single venous anastomosis in the venous drainage of anterolateral thigh free flaps is a safe and feasible option for extremity reconstruction and provides shorter operative time and easy flap dissection.

  • The endovascular recanalization of the iliocaval system has replaced venous surgical reconstructions as the primary treatment option in severe post-thrombotic syndrome (PTS). We herein present a 51-year-old female with previous deep venous thrombosis, complicated with PTS with a large and complex circumferential calf ulcer measuring 25 cm of length in the left lower extremity. Venogram revealed a complete and extensive occlusion in the left iliofemoral system. A surgical bypass from the left common femoral vein to the right common iliac vein was performed. Patient recovered well and after 12 months postoperation her large wound is healing favorably with a clean and well granulated bed. Iliofemoral venous bypass is a feasible treatment for non-healing ulcer of lower extremity.

  • Central venous stenosis is a rare cause of unilateral breast edema occurring in hemodialysis patients that needs to be differentiated from other differential diagnoses, including, but not limited to, inflammatory breast carcinoma, mastitis, lymphedema, and congestive heart failure. All reports of similar cases in the available literature have described improvement or resolution of the edema after treatment. Herein, we report and discuss the pathophysiology of breast edema formation in a patient who presented with massive left-sided breast edema 7 years after being diagnosed with central venous stenosis. Medical and minimally invasive therapy had not been successful, so she underwent reduction mammoplasty to relieve the symptoms.
