Background: The use of ProGlide as a percutaneous vascular closure device in cardiac surgery remains inconclusive. This study investigated the clinical outcomes of using ProGlide in the percutaneous cannulation of femoral vessels in adult cardiac surgery. Methods: From September 2017 to July 2018, 131 consecutive patients underwent femoral vessel cannulation during cardiac surgery. The ProGlide (Abbott Vascular Inc., Santa Clara, CA, USA) with percutaneous cannulation was used in 118 patients (mean age, 55.7±15.5 years). The accessibility of femoral cannulation was evaluated through preoperative computed tomography. For cannulation, sonography was routinely used. The postoperative ankle-brachial index (ABI) was used to evaluate femoral artery stenosis. Results: Of the 118 patients, 112 (94.9%) and 6 (5.1%) underwent minimally invasive cardiac surgery and median sternotomy, respectively. Most femoral cannulations were performed on the right side (98.3%) using 15F to 19F arterial cannulas. The technical success rate of cannulation with ProGlide was 99.2%, with no delayed bleeding or cannulation site-related complications during hospitalization. During follow-up, only 1 patient showed femoral artery stenosis with claudication and was treated with interventional balloon angioplasty. The postoperative ABI revealed no significant difference in functional stenosis between the cannulation and non-cannulation sides (n=86; cannulation vs. non-cannulation, 1.2±0.1 vs. 1.1±0). Conclusion: Percutaneous femoral cannulation with ProGlide was safe and feasible in adult cardiac surgery. This technique may be a good alternative option in patients requiring femoral vessel cannulation for cardiac surgery.

Background: At present, many surgeons prefer axillary artery cannulation because it facilitates antegrade cerebral perfusion and may diminish the risk of cerebral embolization. However, axillary artery cannulation has not been established as a routine procedure because there is controversy about its clinical advantage. Materials and Methods: We examined 111 patients diagnosed with acute type A aortic dissection between January 2000 and December 2009. The right axillary artery was cannulated in 58 patients (group A) and the femoral artery was cannulated in 53 (group F). The postoperative outcomes were retrospectively reviewed and compared between the two groups. Results: There were 46 male and 65 female patients with a mean age of $58.9{\pm}13.1$ years (range, 26 to 84 years). The extent of aortic replacement in both groups did not differ. There were 8 early deaths (7.2%) and 2 late deaths (1.8%). The mean follow-up duration was $46.0{\pm}32.6$ months (range, 1 month to 10 years). Transient neurologic dysfunction was observed in 11 patients (19.0%) in group A and 14 patients (26.4%) in group F. A total of 11 patients (9.9%) suffered from a permanent neurologic dysfunction. Early and delayed stroke were observed in 6 patients (10.3%) and 2 patients (3.4%), respectively, in group A as well as 2 patients (3.8%) and 1 patient (1.9%), respectively, in group F. There were no statistical differences in the cannulation-related complications between both groups (3 in group A vs. 0 in group F). Conclusion: There were no differences in postoperative neurologic outcomes and cannulation-related complications according to the cannulation sites. The cannulation site in an aortic dissection should be carefully chosen on a case-by-case basis. It is important to also pay attention to the possibility of intraoperative malperfusion syndrome occurring and the subsequent need to change the cannulation site.

배경: 급성 상행대동맥박리증 수술 시 대퇴동맥이 동맥삽관 장소로 주로 이용되어 왔으나 최근 관류 장애 및 역행성 색전증의 발생 위험이 적은 액와동맥삽관이 증가하고 있다. 이에 기존의 대퇴동맥 삽관술과 액와동맥 삽관술을 이용한 수술성적을 비교하여 액와동맥 삽관술의 안전성과 유용성을 고찰하고자 하였다. 대상 및 방법: 1995년 10월부터 2001년 9월까지 급성 상행대동맥박리증으로 수술을 받은 71명을 대상으로 의무기록을 후향적으로 검토하여 수슬 전의 상태, 수술범위 및 방법, 수술 후 경과를 분석하였다. 대퇴동맥삽관은 40명으로 평균 연령은 57세, 액와동맥삽관은 31명으로 평균 56세였다. 결과: 액와동맥군의 평균 체외순환시간과 순환정지시간은 각각 207분과 39분으로 대퇴동맥군의 263분과 49분보다 의미있게 짧았고(p<0.05), 수술 후 입원기간 역시 액와동맥군에서 15일로 대퇴동맥군의 35일에 비하여 의미있게 단축되었다(p<0.05). 수술 후 사망률(액와동맥군 6.5%, 대퇴동맥군 10%)과 영구적 신경계 합병증 발생률(액와동맥군 3.2%, 대퇴동맥군 2.5%)은 의미있는 차이를 보이지 않았으나 일시적 신경계 합병증의 발생률은 액와동맥군에서 12.9%, 대퇴동맥군에서 25%로 의미있는 차이를 보였다(p<0.05). 대퇴동맥군 중 2명의 환자에서 수술 중 대동맥궁 분지의 관류 부전이 발견되어 삽관 위치의 변경이 필요하였다. 액와동맥 삽관에 따른 합병증으로는 1명의 환자가 정중신경 손상을 경험하였다. 결론: 급성 상행대동맥박리증 수술에서 액와동맥 삽관은 뇌허혈시간의 단축과 이에 따른 수술 후 신경계 합병증의 발생률을 낮추는 데 기여하는 안전한 술식으로 판단된다. 또한, 이에 따라 대동맥궁에 내피 손상부위가 있는 환자에 대하여 보다 적극적이고 광범위한 수술 적용을 가능하게 한 것으로 판단된다.

A 73-year-old woman who underwent combined bioprosthetic mitral valve replacement, tricuspid ring annuloplasty, and coronary artery bypass grafting 12 years previously visited our clinic due to aggravated dyspnea caused by structural valve deterioration of the mitral prosthesis. Because aortic or femoral artery cannulation and cross-clamping would have a high risk of stroke owing to severe calcification of the ascending aorta and ilio-femoral vessels, and because there was a risk of redo sternotomy due to the patent bypass grafts, a comprehensive approach including axillary artery cannulation, a minimally invasive right thoracotomy approach, and a clampless hypothermic fibrillatory arrest technique was used during redo mitral valve replacement.

Background: Selective antegrade perfusion via axillary artery cannulation along with circulatory arrest under deep hypothermia has became a recent trend for performing surgery on the ascending aorta and aortic arch and when direct aortic cannulation is not feasible. The authors of this study tried using moderate hypothermia with right brachial and femoral artery perfusion to complement the pitfalls of single axillary artery cannulation and deep hypothermia. Materials and Methods: A retrospective analysis was performed on 36 patients who received ascending aorta or aortic arch replacement between July 2005 and May 2010. The adverse outcomes included operative mortality, permanent neurologic dysfunction and temporary neurologic dysfunction. Results: Of these 36 patients, 32 (88%) were treated as emergencies. The mean age of the patients was 61.9 years (ranging from 29 to 79 years) and there were 19 males and 17 females. The principal diagnoses for the operation were acute type A aortic dissection (31, 86%) and aneurysmal disease without aortic dissection (5, 14%). The performed operations were ascending aorta replacement (9, 25%), ascending aorta and hemiarch replacement (13, 36%), ascending aorta and total arch replacement (13, 36%) and total arch replacement only (1, 3%). The mean cardiopulmonary bypass time was $209.4{\pm}85.1$ minutes, and the circulatory arrest with selective antegrade perfusion time was $36.1{\pm}24.2$ minutes. The lowest core temperature was $24{\pm}2.1^{\circ}C$. There were five deaths within 30 post-op days (mortality: 13.8%). Two patients (5.5%) had minor neurologic dysfunction and six patients, including three patients who had preoperative cerebral infarction or unconsciousness, had major neurologic dysfunction (16.6%). Conclusion: When direct aortic cannulation is not feasible for ascending aorta and aortic arch replacement, the right brachial and femoral artery can be used as arterial perfusion routes with the patient under moderate hypothermia. This technique resulted in acceptable outcomes.

We report a case of leaflet embolization of central leaflet fracture a 31mm mitral Edw-ards-Duromedics prosthesis. A leaflet was fractured to two segments, a larger one embolized to right common iliac artery and a smaller one to left femoral artery, respectively. Patient was reoperated with 29mm mitral Carbomedics prosthesis and incidentally found of smaller segment in left femoral artery at cannulation site. The embolectomy was done 15 days after cardiac operation through midline abdominal incision, Leaflet escape of a mitral Edward-Duromedics prosthesis is a rare, potentially curable mode of valve failure. After mechanical valve replacement, unexplained heart failure and acute pulmonary edema, mechanical valve failure should be suspected. Correct interpretation of clinical signs, symptoms and fluroscopy should allow early diagnosis of leaflet escape and prompt surgical therapy.

We experienced 20 cases of acquired aortic diseases during last 1 year [Sep. 1992-Aug. 1993] with newly developed surgical strategies. There were 13 cases[65%] of aortic dissections, 5 cases[25%] of aortic aneurysms and 2 cases of Takayasu arteritis with mean age of 56 + 16 years[range:5-78].In ten cases of patients requiring ascending aortic replacement, femoral artery and femoral vein &/or RA auricle were used as cannulation site. With deep hypothermic circulatory arrest and retrograde cerebral perfusion of cold oxygenated blood via SVC, we can replace the ascending aorta and part of arch if necessary. The mean duration of circulatory arrest was 30 minutes[17-45 min]. In 5 cases of patients who requiring descending and thoracoabdominal aorta replacement, we used simple aortic crossclamping under normothermia with no heparin. The mean duration of aortic crossclamping was 37 minutes[25-50 min].The results of operation were as follow:Operative mortality[2 cases, 10%], delayed cerebral infarct[1], low extremity weakness[1] and intraoperative myocardial infarct[1]. There are no delayed complication or mortality as yet.

This study was undertaken to evaluate current technique of extracorporeal circulation by analyzing the results in 73 cases. We performed standard cardiopulmonary bypass using Polystan roller pump, bubble[Polystan] and membrane[Cobe] oxygenator. There were 42 males and 31 females. We studied the changes of hemoglobin. hemodynamics, speed of cooling and warming, methods of cannulation and ACT. Arterial cannula was inserted on ascending aorta except for 7 cases of femoral cannulation. Preoperative hemoglobin was 13.2 gm% and this value dropped to 7.5 gm% during perfusion. Blood pressure of 113 mmHg in systolic dropped 57mmHg in 10 minutes of perfusion and became 98 mmHg at the end of perfusion. Initial drop of blood pressure was marked in pediatric patient. Mean cooling time was 19.4 min[0.54 Q /min] and warming time was 34 minutes[0.25 Q /min]. During perfusion, ACT was maintained above 600 sec and 44 patient did not need additional Heparin.

Dissecting aortic aneurysm of ascending aorta is a life threatening condition which requires prompt surgical correction. With deep hypothermic circulatory arrest and retrograde cerebral perfusion via superior vena cava, we could replaced ascending aorta in 4 cases safely. All of 4 cases; femoral artery, right auricle were used as cannulation site. The duration of circulatory arrest were 28, 30, 45, 60 minute in each cases and rectal temperature was 2$0^{\circ}C$ at that time. At the time of retrograde cerebral perfusion, we maintained central venous pressure under 25mmHg. We resected all of dissecting portion and replaced it with Hemashield graft. There were no deaths but two of four reoperated because of bleeding.

Advanced esophageal carcinoma which invades into adjacent organs are classified as T4 esophageal cancer,. Its complete resection without residual tumor would be difficult. Preoperative chemoradiotherapy and combined modality therapy are being tried to improve survival in patients with T4 esophageal carcinoma. In a 74-year-old man a 6cm squamous cell carcinoma of the esophagus with invasion of the thoracic aorta was detected (T4). After neoadjuvant chemoradiotherapy the patient was operated on using bio-pump with aorto-femoral cannulation. The invased segment of descending aorta was resected and reconstructed with a graft. The tumor was resected and EG anastomosis was done. The postoperative period was uneventful the patient was discharged after good condition and has been well to now.
