  • The entrapment of the popliteal artery is a rare cause of ischemia of the lower extremities among young males. The development of local occlusive or aneurysmal changes of the popliteal artery is caused by abnormal anatomic relationships between vascular and musculo-tendinous structures in the popliteal fossa. An 18-year-old male visited our outpatient clinic with the chief complaint of claudication in his right calf. Three dimensional CT angiography showed an occlusion of the popliteal artery and less opacified arteries of the right leg. Intraoperatively, the popliteal artery was compressed by an accessory muscle band arising from the medial head of the gastrocnemius. After release of the muscle band, thrombectomy with endarterectomy was done. Three years after surgery, he is doing well without any problems.

  • Hematoma is quite a common complication of femoral arterial catheterization. However, to the best of our knowledge, there have been no previous studies regarding deep vein thrombosis (DVT) caused by compression of a vein due to a hematoma. We report a case of a hematoma developing after femoral arterial catheterization and causing extensive symptomatic DVT. A 59-year-old male was seen in our Emergency Department with right lower leg swelling 15 days after coronary stent implantation performed using right femoral artery access. Computed tomographic (CT) scanning revealed a large hematoma (45 mm in its longest diameter) compressing the common femoral vein and with DVT from the right external iliac vein to the popliteal vein. Due to the extensive DVT involvement, we decided to release the compressed common femoral vein by surgical evacuation of the large hematoma. However, even following evacuation of the hematoma, as the DVT did not resolve soon, further mechanical thrombectomy and catheter-directed thrombolysis were performed. Angiography then showed nearly resolved DVT, and the leg swelling was improved. The patient was discharged with the anticoagulation medication, warfarin.

  • Objective : Cerebral vasospasm is a common and potentially devastating complication of aneurysmal subarachnoid hemorrhage (aSAH). Inflammatory processes seem to play a major role in the pathogenesis of vasospasm. C-reactive protein (CRP) constitutes a highly sensitive inflammatory marker. Elevation of serum CRP levels has been demonstrated in patients with aSAH. The purpose of the current study was to evaluate the possible relationship between CRP levels in the serum and transcranial Doppler (TCD) and the development of vasospasm in patients with aSAH. Methods : A total of 61 adult patients in whom aSAH was diagnosed were included in the study from November 2008 to May 2011. The patients' demographics, Hunt and Hess grade, Fisher grade, CT scans, digital subtraction angiography studies, and daily neurological examinations were recorded. Serial serum CRP measurements were obtained on days 1, 3, 5, 7, 9, 11 and 13 and TCD was measured on days 3, 5, 7, 9, 11 and 13. All patients underwent either surgical or endovascular treatment within 24 hours of their hemorrhagic attacks. Results : Serum CRP levels peaked on the 3rd postoperative day. There were significant differences between the vasospasm group and the non-vasospasm group on the 1st, 3rd and 5th day. There were significant differences between the vasospasm group and the non-vasospasm group on the 3rd day in the mean middle cerebral artery velocities on TCD. Conclusion : Patients with high levels of CRP on the 1st postoperative day and high velocity of mean TCD on the 3rd postoperative day may require closer observation to monitor for the development of vasospasm.

  • Purpose: Autologous fat injection is ideal for patients who wish to add contour, projection and gross volumization of the aging, atrophic face and is claimed to be a safe procedure. However, there are several case reports in the literature where patients have suffered from acute visual loss and cerebral infarction after facial fat injection. This paper will explore a rare case of vessel related complication, an arteriovenous fistula that occurs after fat injection on forehead. Method: A 28 - year - old female who showed a non - tender, soft $1.0{\times}2.5cm$ sized mass on forehead for 3 weeks. A thrill could be detected on the totuous dilatated vessel - like structure around the mass. She had a fat injection on forehead for soft tissue augmentation 3 months prior to developing the mass. 3 - dimensional brain CT angiography showed arteriovenous fistula. Results: The fistula is totally excised with ligation of feeding vessels. Pathology report showed an atypical vessel which had intimal thickening, myxoid degeneration and thrombus formation. There were no evidences of recurrence at least for 2 months of follow - up. Conclusion: An occurrence of arteriovenous fistula after autologous fat injection is very rare. After perforation of artery and vein by coincidence, blood extravasates with the formation of a hematoma capsule and a pseudocapsule around it. The hematoma capsule would expand and clot would reabsorb resulting in a cavity leading to fistula formation. Other vessel related complications like acute visual loss or cerebral infarction are very severe. Therefore, surgeons should be cautious during facial fat injection to avoid vessel injuries.

  • Purpose: Autologous breast reconstruction with abdominal tissue is one of the best options after mastectomy. In a free transverse rectus abdominis myocutaneous(TRAM) or deep inferior epigastric artery perforator(DIEP) flap, a preoperative evaluation of the precise location of perforating vessels and vascular run - off systems is required. The objective of this report is to demonstrate the usefulness of multidetector computed tomography(MDCT) in the preoperative planning of patients undergoing breast reconstruction with abdominal flap. Methods: From June 2006 to January 2008, 28 patients underwent MDCT evaluation before breast reconstruction. All subjects were females with an age range of 30 to 55 years. The CT scan was performed using a 64 - slice MDCT scanner(Brilliance 64; Philips Medical Systems, Best, Netherlands). Results: One perforator or two major perforators were marked on image in good relation with a hand - held Doppler examination and intraoperative findings. All vascular run - off systems were cleared before operation. Conclusion: Preoperative evaluation of perforator arteries with MDCT angiography is beneficial in patients undergoing breast reconstruction. This technique provides a noninvasive approach of the vascular anatomy of the entire anterior abdominal wall.

  • Pseudoaneurysm of the splenic artery may arise from a vascular erosion by a surrounding inflammatory processes in acute and chronic pancreatitis. Rupture of the pseudoaneurysm may threaten the patient's life. Conservative management for massive hemorrhage may cause 100 percent mortality and even with prompt therapy there is a high mortality. Preoperative detection of bleeding source is desirable because of the difficult identification of the bleeding site at laparotomy. Angiographic identification and embolization of the hemorrhagic vessels in selected cases may obviate the risk of urgent surgery. The authors have recently managed a case of ruptured splenic artery pseudoaneurysm combined with a pancreatic pseudocyst in a 6 years old boy. A bolus enhanced CT scan and angiography confirmed the diagnosis. We managed this child successfully with the urgent transcatheter arterial embolization followed by elective surgery.

  • A 3-month-old intact male Lakeland terrier was presented with recurring regurgitation after removing cervical esophageal foreign body by endoscopy. Blood and urine analysis, radiography, ultrasonography, fluoroscopic esophagography, computed tomographic angiography (CTA) were performed. In radiography and fluoroscopic esophagography, vascular ring anomaly was considered as the primary cause of megaesophagus, and CTA with gas-inflation of the esophagus was performed. Compressed esophagus, persistent right aortic arch (PRAA), aberrant left subclavian artery (LSA), and a venous structure which was confirmed in surgery to be incomplete type persistent left cranial vena cava (PLCVC) connected with the left side azygos vein were observed. Left deviation of the trachea was also revealed in CT, which implies the compression by left ligamentum arteriosum. Therefore, type 3 PRAA with left ligamentum arteriosum and aberrant LSA, was considered as a prior differential diagnosis. Surgical repair was performed and the clinical signs improved. This report describes CTA characteristics of combination of PRAA with aberrant LSA, incomplete PLCVC and Lt. azygos vein in a dog. Although not every vascular anomaly does induce clinical sign, some types can complicate the surgical procedure, and cause clinical signs. Therefore, thorough evaluation of vascular anomalies in the thorax is important, and CTA is a useful method in identifying multiple vascular anomalies in dogs.

  • Recent literature reveals that pulmonary embolism secondary of pulmonary tumor embolism are dyspnea, hemoptysis, pulmonary hypertension, and circulatory collapse. We experienced a case of pulmonary embolism secondary to hepatocelluar cancer in 53-year-old man. From 2 months before admission, he began to experience cough and mild shortness of breath. Within a few days these symptoms progressed to near total incapacity. Pulmonary embolism was confirmed by angiography and the diagnosis of hepatocellular cancer was estabillished by abdomen CT and $\alpha$-FP(21,000 ng/ml). There was no evidence of intravascular cogulation elsewhere in deep vein of the extremities or risk factors of deep vein thrombosis. Thus we consider that pulmonary embolism in this patients is related to hepatocellular cancer rather than deep vein thrombosis. Therefore we report the first case which hepatocellular cancer initially presented as pulmonary embolism in Korean literature.

  • Background Free tissue transfer is considered the gold standard option for the reconstruction of distal leg defects. Free tissue transfer using recipient vessels in the contralateral leg (cross-leg bridge) is a potential option to supply the flap if there are no suitable recipient vessels in the injured leg. Most studies have described this technique using end-to-end anastomosis which sacrifices the main vessel in the uninjured leg. This study evaluated the use of a cross-leg free latissimus dorsi muscle flap for the reconstruction of defects in single-vessel legs, using end-to-side anastomosis to recipient vessels in the contralateral leg without sacrificing any vessel in the uninjured leg. Methods This is a retrospective study that included 22 consecutive patients with soft tissue defects over the lower leg. All the reconstructed legs had a single artery as documented by CT angiography. All patients underwent cross-leg free latissimus dorsi muscle flap using end-to-side anastomosis to the posterior tibial vessels of the contralateral leg. Results The age at surgery ranged from 12 to 31 years and the mean defect size was 86 cm2. Complete flap survival occurred in 20 cases (91%). One patient had total flap ischemia. Another patient had distal flap ischemia. Conclusion Cross-leg free latissimus dorsi muscle flap is a reliable and safe technique for the reconstruction and salvage of mutilating leg injuries, especially in cases of leg injuries with a single artery. As far as preservation of the donor limb circulation is concerned, end-to-side anastomosis is a reasonable option as it maintains the continuity of the donor leg vessels.

  • Cervicovaginal venous malformations are extremely rare. Sclerotherapy is proven to be effective for superficial venous malformations but not for venous malformations in the lower genital tract of female. A 52-year-old female presented with intermittent vaginal bleeding. The amount of vaginal bleeding gradually increased over 3 months. Contrast-enhanced pelvis CT showed several phleboliths and dilated vessels, but pelvic angiography showed no early draining veins, nidus, or feeding artery. We performed transvaginal direct puncture and ethanol sclerotherapy rather than surgical treatment because she wanted to preserve the uterus. After four sessions of sclerotherapy, she had significantly decreased vaginal bleeding without complications. Here, we report the first case of cervicovaginal venous malformations successfully treated with transvaginal direct puncture and ethanol sclerotherapy.
