71세 남자 환자로 좌측 총장골 동맥의 완전 폐쇄를 동반한 복부 대동맥류로 수술하였다. 술 전, 좌측 대퇴 및 장골 정맥에 동반된 만성 심부정맥 혈전증은 진단하지 못 하였다. 동맥류 절제술 및 우측은 외측 장골동맥에, 좌측은 대퇴동맥에 문합한 Y-graft 치환술과 대퇴동맥간 우회술을 시행하였으나, 술 후 반복적인 부종과 통증이 발생하였고 점차 악화되어 결국 광범위한 정맥 혈전증으로 사망하였다. 본례는 만성 심부정맥 혈전증을 동반한 폐쇄성 대동맥 장골 동맥 질환에 있어 수술적 치료 및 합병증에 관한 보고이다.

Iatrogenic vascular injury (IVI) can occur with any technique or type of surgery performed around a blood vessel. Patients with severe trauma are at risk of IVI. In this study, we describe our experiences of IVI in the trauma field. We reviewed five patients who were diagnosed with an IVI and received either surgical or endovascular treatment. Of the five patients, one had an arterial injury, three had venous injuries, and one had an arteriovenous fistula, a form of combined arterial and venous injuries. Of the five patients, four had undergone orthopedic surgery. The IVIs of three patients were immediately identified in the operating room and simultaneous vascular repair was performed. The remaining one patient underwent additional surgery for occlusion related to entrapment of the superficial femoral artery by a surgical wire used during orthopedic surgery. Complications presumably related to the IVI were identified in two patients. IVI in trauma patients can be successfully managed, but significant morbidity can occur. If an IVI is suspected, immediate evaluation and management are required.

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.

목적 혈액투석용 자가혈관 동정맥루의 혈전을 동반한 폐색에서 경피적 수동 흡인 혈전제거술의 안전성과 유용성에 대해 평가하고자 한다. 대상과 방법 2012년 3월부터 2017년 12월까지 자가혈관 동정맥루의 혈전을 동반한 폐색으로 내원하여 경피적 혈관 내 시술을 시행 받은 20명의 환자를 후향적으로 분석하였다. 기술적 및 임상적 시술 성공률, 1차 및 2차 개통률, 그리고 시술에 따른 합병증을 분석하였다. 결과 총 20명의 환자에서 20회의 경피적 혈관 내 시술을 시행하였다. 모든 환자에서 혈전을 제거하기 위해 경피적 수동 흡인 혈전제거술을 시행하였고, 협착이 동반된 경우 풍선카테터를 이용한 혈관성형술을 함께 시행하였다. 17명의 환자는 혈전이 제거되어 혈류가 정상적으로 회복되었고(기술적 성공률 85%), 17명 환자 모두 시술 직후 혈액투석이 정상적으로 시행되었다(임상적 성공률 85%). 동정맥루 위치는 좌측 요골두정맥루가 13명, 좌측 상완두정맥루가 4명, 우측 요골두정맥루가 3명이었다. 동반된 협착 부위는 문합부 주위 정맥이 16예, 원위부 배출정맥이 12예, 중심정맥이 4예였다. 1차 및 2차 개통률은 1, 3, 6, 12개월에서 각각 100%, 70.6%, 70.6%, 56.5% 및 100%, 94.1%, 94.1%, 86.9%였다. 시술과 관련된 합병증은 없었다. 결론 혈액투석용 자가혈관 동정맥루에서 혈전을 동반한 폐색의 치료로서 경피적 수동 흡인 혈전제거술은 안전하고 유용한 시술이다.

Backgrounds/Aims: Extra hepatic portal venous obstruction (EHPVO) is the most common cause of portal hypertension in Indian children. While endoscopy is the primary modality of management, a subset of patients require surgery. This study aims to report the short- and long-term outcomes of EHPVO patients managed surgically. Methods: All the patients with EHPVO who underwent surgery between August 2007 and December 2021 were retrospectively reviewed. Postoperative complications were classified after Clavien-Dindo. Binary logistic regression in Wald methodology was used to determine the predictive factors responsible for unfavourable outcome. Results: Total of 202 patients with EHPVO were operated. Mean age of patients was 20.30 ± 9.96 years, and duration of illness, 90.05 ± 75.13 months. Most common indication for surgery was portal biliopathy (n = 59, 29.2%), followed by bleeding (n = 50, 24.8%). Total of 166 patients (82.2%) had shunt procedure. Splenectomy with esophagogastric devascularization was the second most common surgery (n = 20, 9.9%). Nine major postoperative complications (Clavien-Dindo > 3) were observed in 8 patients (4.0%), including 1 (0.5%) operative death. After a median follow-up of 56 months (15-156 months), 166 patients (82.2%) had favourable outcome. In multivariate analysis, associated splenic artery aneurysm (p = 0.007), isolated gastric varices (p = 0.004), preoperative endoscopic retrograde cholangiography and stenting (p = 0.015), and shunt occlusion (p < 0.001) were independent predictors of unfavourable long-term outcome. Conclusions: Surgery in EHPVO is safe, affords excellent short- and long-term outcome in patients with symptomatic EHPVO, and may be considered for secondary prophylaxis.

A 66-year-old woman presented with intermittent paraparesis and generalized tonic-clonic seizure. Cerebral angiography demonstrated dural arteriovenous fistula (AVF) involving superior sagittal sinus (SSS), which was associated with SSS occlusion on the posterior one third. The dural AVF was fed by bilateral middle meningeal arteries (MMAs), superficial temporal arteries (STAs) and occipital arteries with marked retrograde cortical venous reflux. Transfemoral arterial Onyx embolization was performed through right MMA and STA, but it was not successful, which resulted in partial obliteration of dural AVF because of tortuous MMA preventing the microcatheter from reaching the fistula closely enough. Second procedure was performed through left MMA accessed by direct MMA puncture following small decortications of cranium overlying the MMA using diamond drill one week later. Microcatheter could be located far distally to the fistula through 5 F sheath placed into the MMA and complete obliteration of dural AVF was achieved using 3.9 cc of Onyx.

High-flow vertebral arteriovenous fistulas (VAVF) are rare complications of cervical spine surgery and characterized by iatrogenic direct-communication of the extracranial vertebral artery (VA) to the surrounding venous plexuses. The authors describe two patients with VAVF presenting with ischemic presentation after C1 pedicle screw insertion for a treatment of C2 fracture and nontraumatic atlatoaxial subluxation. The first patient presented with drowsy consciousness with blurred vision. The diffusion MRI showed an acute infarction on bilateral cerebellum and occipital lobes. The second patient presented with pulsatile tinnitus, dysarthria and a subjective weakness and numbness of extremities. In both cases, digital subtraction angiography demonstrated high-flow direct VAVFs adjacent to C1 screws. The VAVF of the second case occurred near the left posterior inferior cerebellar artery originated from the persistent first intersegmental artery of the left VA. Both cases were successfully treated by complete occlusion of the fistulous portion and the involved segment of the left VA using endovascular coil embolization. The authors reviewed the VAVFs after the upper-cervical spine surgery including C1 screw insertion and the feasibility with the attention notes of its endovascular treatment.

We performed three replacement operations of great venous obstruction with Dacron prosthesis from July, 1980 to Nov. 1980. Summary of 3 cases as belows: 1) Inferior vena cava obstruction . 43 years old male was admitted because of abdominal distension and marked superficial collateral circulation on chest and abdomen. Inferior vena cavogram showed complete obstruction of I. V .C. just below hepatic vein. Bypass operation was done between Rt atrium '||'&'||' I. V.C. (just above renal vein) with Woven Dacron prosthesis (22mm in Diameter) under ex tracorporeal ci rculation. 2) Superior vena cava obstruction . 21 years old male was admitted because of facial edema and irritative cough. Well circumscribed lobulated mass was located at ant. superior mediastinum and extended to Rt. thorax in chest P-A view. Woven Dacron prosthesis (10mm in Diameter) was replaced at involved S.V.C. segment after Rt. upper '||'&'||' middle lobectomy with tumor resection. 3) Common iliac vein obstruction (Lt) . 64 years old female was admitted because of generalized edema and tenderness of Lt. lower extremity. Venography of Lt leg showed complete obstruction of common iliac vein. Woven Dacron prosthesis (10mm in Diameter) was replaced at obstruction site.eplaced at obstruction site.
