Lower extremity deep vein thrombosis (DVT) is a serious medical condition that can result in local pain and gait disturbance. DVT progression can also lead to death or major disability as a result of pulmonary embolism, postthrombotic syndrome, or limb amputation. However, early thrombus removal can rapidly relieve symptoms and prevent disease progression. Various endovascular procedures have been developed in the recent years to treat DVT, and endovascular treatment has been established as one of the major therapeutic methods to treat lower extremity DVT. However, the treatment of lower extremity DVT varies according to the disease duration, location of affected vessels, and the presence of symptoms. This article reviews and discusses effective endovascular treatment methods for lower extremity DVT.

Pulmonary thromboembolism originated most commonly from the venous thrombus, especially deep vein thrombus in the leg, which migrated to and occluded the pulmonary vasculatures. The failure of clot lysis and repeated embolic episodes resulted in the hemodynamic compromise -that is- in the increasing in the pulmonary vascular resistance, which would cause the right ventricle failure[Car Pulmonale]. Under the cardiopulmonary bypass, 20 year old male patient was treated successfully by thromboembolectomy of pulmonary thromboembolism with pulmonary hypertension, which originated from the deep vein thrombus in the leg. The results of radiologic studies and clinical evaluations were excellent in that the postoperative lung perfusion scan showed the newly increased perfusion of post-embolectomy territories and in the arterial blood gas finding of 76 from 66[mmHg] in PaO2. The patient was uneventful and discharged on postop. $ 14 days with anticoagulant continued.

세균성 근염은 화농성 관절염, 봉와직염, 골수염, 혈전 정맥염, 다발성 근염, 혈종, 좌상, 종양과 감별이 필요하며 진단에 MRI가 도움이 된다. 저자들은 A군 사슬알균에 의한 화농성 근염을 조기에 진단하여 clindamycin으로 치료하였고 심부정맥 혈전증까지 합병되었던 환자를 경험하였다. 성인에서는 증례로 보고된 바가 있지만 국내에서는 아직 보고가 없어 이를 보고하는 바이다.

Although the success rate of deep inferior epigastric perforator (DIEP) flaps has increased, late flap failures still occur and have a low salvage rate. The present article describes a case of salvage of a case of late flap failure using the pedicle vein as a vein graft source. A 50-yearold woman underwent a bilateral DIEP free flap procedure. On postoperative day 6, she experienced flap compromise and underwent emergency flap revision. In the flap revision, flap venous drainage and the superficial inferior epigastric vein were completely obstructed. A Fogarty catheter was used to remove a thrombus from the completely obstructed pedicle vein, and this pedicle vein was used as a graft source and was ligated in retrograde fashion to the flap vein stump. After injection of urokinase into the arterial branch, venous flow to the flap was restored. At a 6-month follow-up visit in the outpatient clinic, only partial fat necrosis at the flap was noted. By dissecting various perforators in the initial operation, decisions regarding immediate revision can be made with more confidence. Additionally, the combined procedures performed in this case may be helpful even for practitioners treating cases of late flap compromise.

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.

64세 남자가 혈뇨를 주소로 입원하여 하대정맥으로 종양 혈전이 파급된 우측 신세포암으로 진단받았다. 우신 적출술 시행 후 역행성 뇌관류하면서 심도 저체온 순환정지 하에 하대정맥 혈전 제거술을 시행하였다. 종양 혈전은 우 신에서 기원하여 하대정맥으로 자라면서 좌 신정맥의 생식선정맥 유입구까지, 위로는 간정맥 유입부까지, 아래로는 신정맥 하방 3cm까지 파급되어 있었다. 심도 저체온 순환 정지 하에서 하대정맥 손상 없이 혈전을 완전히 제거하였고 술 후 경과는 순조로웠다. 술 후 인터페론 면역 치료를 받았고 특별한 문제없이 추적관찰 중이다.

Numerical analysis was performed on the enzyme transport and the flow fields in order to predict the effectiveness of urokinase injection regimens in clot dissolution. The species and momentum transport equations were numerically solved for the case of uniform perfusion of enzyme into a fibrin clot for an arterial thrombus and a deep vein thrombus models. In order to predict the thrombus lysis efficiency of continuous and forced intermittent injections, enzyme perfusion and clot lysis were simulated for the different injection velocities. Intermittent injection showed faster clot lysis compared to continuous perfusion, and lysis efficiency was increased as injection velocity increased.

Pulmonary thromboembolism originated mostly from the venous thrombus, especially deep vein thrombosis in the lower extremities, which migrated upward and lodged the pulmonary vasculatures, Massive pulmonary thromboembolism usually leads to in \ulcornerhospital mortality if the patient was not treated properly. Under the cardiopulmonary bypass, a 49-year old man was treated successfully by emergent pulmonary embolectomy of pulmonary thromboembolism, which originated from the deep vein thrombosis in the right leg. Ligation or filtering device insertion of the inferior vena cava was not performed. The patient’s postoperative course was uneventful and discharged on postoperative 15th day He continued to receive oral anticoagulation with aspirin and persantin, which had been started on the third postoperative day. And he was well till recent days through the outpatient follow-up. The clinical courses of this patient are described, and massive pulmonary embolism and its management are discussed.
