  • Purpose: The purpose of this study is to present extended indications for the use of arterialized venous flaps in reconstructing soft tissue, tendon, nerve, blood vessel, and composite tissue defects of the hand of various sizes based on researches and clinical experiences of the authors. Moreover, procedures to achieve complete flap survival and postoperative results are presented. Materials & methods: This study is based on 154 cases of arterialized venous flaps performed to reconstruct the hand during the past 11 years. The most common cause of injury was industrial accidents with 125 cases. One hundred thirty patients or 84% of the cases had emergency operation within 2 weeks of the injury. The flaps were categorized depending on the size of the flap. Flaps smaller than $10\;cm^2$ were classified as small (n=48), those larger than $25\;cm^2$ classified large (n=42) and those in between medium (n=64). Classified according to composition, there were 88 cases (57.1 %) of venous skin flaps, 28 cases of innervated venous flaps, 15 cases of tendocutaneous venous flaps, which incorporated the palmaris longus tendon, for repair of extensor tendons of the fingers, and 17 cases of conduit venous flaps to repair arterial defect. There were 37 cases where multiple injuries to multiple digits were reconstructed. Moreover, there were 6 cases of composite tissue effects that involved soft tissue, blood vessels and tendons. The donor sites were ipsilateral forearm, wrist and thenar area, foot dorsum, and medial calf. The recipient sites were single digit, multiple digits, first web space, dorsum and palm of hand, and wrist. Results: There were seven cases (4.5%) of emergent re-exploration due to vascular crisis, and 3 cases of flap failure characterized by more than 50% necrosis of the flap. The survival rate was 98.1 % (151/154). In small flaps, an average of 1.01 afferent arteries and 1.05 efferent veins were microanastomosed, and in large flaps, an average of 1.88 afferent arteries and 2.19 efferent veins were anastomosed. In 8 cases where innervated flaps were used for reconstructing the palm of the hand, the average static two-point discrimination was $10\;(8{\sim}15)\;mm$. In 12 cases where tenocutaneous flaps were used, active range of motion at the proximal interphalangeal joint was 60 degrees, 20 degrees at the distal interphalangeal joint, and 75 degrees at the metacarpophalangeal joint. Conclusion: We conclude that the arterialized venous flap is a valuable and effective tool in the reconstruction of hand injuries, and could have a more comprehensive set of indications.

  • Digit that were formerly assessed as non replantable may now be replanted with the help of salvage procedure. In case that, venous repair is either marginal or technically impossible and postoperative venous congestion developed following replantation, are treated with the application of medical leeches. From July 1997 to April 1998, the authors performed arterial anastomosis and venous drainage using medical leeches in 3 children(The age of the patients ranged from 13 months to 6 years.) to have a result of aesthetic and functional success with minimizing the complications. Leech therapy has many advantages, to avoid injuring of finger tip, to decrease focal capillary coagulation, to prevent severe bleeding, and to prevent thromboembolism. The authors conclude that the use of medical leeches shows promise as a safe and effective method of providing temporary venous drainage in replanted digits.

  • Background: This study examined the role of superficial vein surgery in patients with combined superficial venous reflux and segmental popliteal vein reflux. Methods: We retrospectively reviewed 42 limbs in 38 patients with combined superficial venous reflux and segmental popliteal vein reflux who underwent saphenous vein ablation between January 2014 and February 2017. Patients underwent outpatient follow-up duplex ultrasonography at 3, 6, and 12 months postoperatively. Resolution of deep vein reflux was defined as reversed blood flow in a popliteal segment for less than 1.0 second and a decrease in the reflux time of more than 20% of the preoperative reflux time. Results: The mean follow-up period was 9 months (range, 3-23 months). Saphenous vein ablations were performed by stripping in 24 limbs and radiofrequency ablation in 18 limbs. Preoperative segmental popliteal vein reflux resolved in 21 of the 42 limbs (50%). Conclusion: This study demonstrated that superficial venous surgery corrected segmental popliteal vein reflux in 50% of limbs with combined superficial venous reflux and segmental popliteal vein reflux. Other prospective studies are necessary to elucidate the etiology of the non-reversible cases.

  • Purpose: The purpose of this study was to identify the types of venous access devices (VAD) for cancer patients and investigate the factors related to the insertions of central venous catheter (CVC) in cancer patients. Methods: The subjects were 379 cancer patients. A retrospective review of all patients who were discharged from a cancer unit from November 1st to 21st in 2008 was done using a structured questionnaire. Results: A total of 82 CVC (21.6%) was inserted among 379 patients for administering anticancer therapy. There were statistically significant differences in age, length of stay (LOS), cumulative LOS, medical department, history of CVC insertion, cancer category, and albumin level between patients using peripheral intravenous (IV) catheters and CVC. In addition, factors influencing the use of CVC were LOS (odds ratio [OR]=0.286, confidence interval [CI]=1.043-1.124), history of CVC insertion (OR=3.920, CI=0.128-0.637), albumin level (OR=1.010, CI=1.879-8.179), cumulative LOS (OR=1.010, CI=1.001-1.018), and hematological diseases (OR=4.863, CI=2.162-10.925). Conclusion: We found that central venous catheterization for anticancer therapy was minimal even though CVC was safe and effective device for IV access. It is necessary to develop a strategy to use VADs efficiently and timely for cancer patients.

  • Purpose: The purpose of this study was to identify effects of EMLA (Eutectic Mixture of Local Anesthetics) cream application on pain perception and pain response during insertion of implanted venous access port needle in children with cancer. Methods: From December 2010 to August 2011, at U university hospital, 20 patients scheduled for implanted venous access port needle insertion were recruited, and randomly assigned to receive either EMLA or a placebo cream 1 hour before the implanted venous access port needle insertion. While conducting needle insertion, changes in pulse and oxygen saturation on the pulse oxymeter monitor were measured and pain behavior reaction was also measured during needle insertion in the treatment room. After conducting needle insertion, self-reported pain reaction, and mothers' perception of the children's pain reaction were measured. Collected data were statistically processed using SPSS version 17.0 for Windows, and analyzed using descriptive statistics, t-test. Results: Children's self-reported degree of pain, degree of pain as perceived by mothers and pain behavior reaction decreased significantly in the EMLA application group compared with the placebo group. Conclusion: Findings indicate that application of EMLA cream is effective in relieving pain in these children during implanted venous access port needle insertion.

  • We will report 6 cases of cardiac tamponade treated surgically at Severance Hospital during the past 9 years from 1964 to 1972 and reviewed literatures on cardiac tamponade. The age of patients was from 13 years to 45 years old. The male was 4 cases and the female 2 cases. The sites of injury were right atrium; 1 case, right ventricle; 2 cases, right ventricle and coronary artery; 1 case, left atrium; 1 case, and left ventricle; 1 case. 2 cases of cardiac tamponade developed following chest injury, 2 cases following pericardiocentesis,1 case due to continuous bleeding from sutured cardiotomy wound of left atrium following open mitral commissurotomy using cardiopulmonary bypass machine, and 1 case due to traumatic penetration of polyethylene catheter through right ventricle to pericardial sac, introduced via right jugular vein in order to monitor the central venous pressure. Central venous pressure was checked preoperatlvely in 5 cases. In all cases, central venous pressure was rised [the range of central venous pressure was 240 to 330 mmHg]. Immediately after operation,central venous pressure lowered to normal [the range was 80-100 mmHg]. Recently serial gas analysis of arterial blood were checked pre- and post-operatively for the evaluation of hemodynamic change of cardiac tamponade, but our data was not enough for evaluation. It should be studied further.

  • 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.

  • Cutaneous squamous cell carcinoma (CSCC) overlying an arteriovenous fistula (AVF) is rare and presents unique challenges. This case report describes a method of fistula preservation after CSCC excision using a flow-through venous free flap. The saphenous vein of the venous flap was used as flow-through segment for AVF preservation. The flap was inserted along the dorsal aspect of the forearm wound and microvascular anastomosis of the arterial inflow was completed using a vein just proximal to the radiocephalic fistula anastomosis. Venous outflow was established by creating an end-to-end vascular anastomosis between the cephalic vein and the greater saphenous vein. A separate subcutaneous vein was used to provide a low-pressure outflow for the flap to avoid congestion. This case demonstrates an option for AVF preservation that has not been previously described. It also highlights the importance of a multidisciplinary approach for the safe treatment of CSCCs overlying AVFs.

  • Purpose : In evaluation of patients, laboratory results are crucial in determination of a treatment plan. Obtaining venous blood from infants and children is a difficult procedure. Substitution of a capillary blood sample for a venous blood sample has been suggested. However, there are few studies showing mutual correlation between C-reactive protein (CRP) results in capillary and venous blood. This study was designed to determine whether the result of the capillary sample is the same as the result of the venous blood sample. Methods : After informed consent, a pair of venous and fingertip capillary blood samples were simultaneously collected from 100 children. The LC-178CRPTM was used for analysis of capillary blood and the Hitachi 7180 automatic hematology analyzer was used for analysis of venous blood. We compared CRP of both venous and capillary blood samples. Results were analyzed by crosstabulation analysis, simple regression analysis and the Bland Altman Plot method. Results : A close correlation (90.63%) was observed between capillary and venous blood analyzed by crosstabulation analysis. CRP results were similar between the two groups and showed a high coefficient correlation ($\beta$=1.3434, $R^2$=0.9888, P<0.0001) when analyzed by a simple regression model. The average value in venous blood was also higher compared to capillary blood. According to Bland Altman Plot analysis, lab results were measured at a 95% confidence interval. Conclusion : CRP results from capillary blood showed close correlation with venous blood sampling. At present, venous blood sampling is the preferred method. However, due to difficulty in venous blood sampling, capillary sampling could be considered as an alternative technique for use with children.

  • Anomalous systemic venous return to the right atrium is clinically innocuous and cause no functional disturbances or physiologic abnormalities by themselves and consequently require no treatment but may be surgical importance. We experienced a case of adult TOF combined with anomalous systemic venous drainage. Rudimentary right SVC with draining left sided vertical vein and IVC with separately drained left vein was revealed at operation time. With the bicaval cannulation, large sucker was used for drainage of blood from the left hepatic vein. Postoperative angiocardiogram showed above findings and combined double inferior vena cava at lumbar level.
