배경: 본 연구는 심폐바이패스를 사용하지 않는 관상동맥우회술 중 발생한 혈역학적 불안정에 대한 대동맥내 풍선펌프 치료의 유용성을 평가하고자 하였다. 대상 및 방법: 2000년 1월부터 2006년 12월까지 심폐바이패스를 사용하지 않는 관상동맥우회술을 받은 796명의 환자를 대상으로 하였다. 수술중 대동맥내 풍선펌프 삽입이 필요했던 환자들을 I군(n=39), 삽입하지 않았던 환자들을 II군(n=757)으로 분류하였다. 결과: 두 군간에 수술 사망률(2.6%, 1/39 vs. 0.8%, 6/757; p=0.195)과 심방 세동(p=0.691), 뇌졸중(p=0.908), 종격동염(p=0.781) 이환율의 차이는 없었다. 인공호흡기 치료 시간, 중환자실 및 병원 재원 기간은 I군에서 II군보다 길었다 (p<0.05). 다변량 분석에서 수술 중 대동맥내 풍선 펌프 삽입이 수술 사망률을 유의하게 증가시키진 않았다(p=0.549). I군에서 대동맥내 풍선 펌프 치료와 관련하여 수술적 치료가 필요했던 합병증이 3예 있었으나(7.9%), 대동맥내 풍선 펌프 삽입 술기를 변형한 2003년 이후에는 발생하지 않았다. 결론: 심폐바이패스를 사용하지 않는 관상동맥우회술 중 혈역학적 불안정이 발생한 경우 대동맥내 풍선펌프를 이용하여 비교적 적은 합병증으로 관상동맥우회술을 시행할 수 있었다.

1994년 5월부터 1995년 12월까지 성인에서 심장수술을 시행한 122례중 18례(14.8%)에서 IABP를 순환보조장치로 사용하였다. 그중 술전에 IABP(intra-aortic balloon pump)를 시행한 경우는 9례이고, 술 중에는 7례, 그리고 술후에는 2례에서 시행하였다. 그 이유는 술전에는 저심박출, PTCA(percutaneous transluminal coronary angioplasty)의 실패였고, 술중에는 체외순환기 이탈을 위해서이며, 술후에는 술후 발생한 부정 맥 때문이었다. 환자들의 평균 나이는 61.8$\pm$6.9세(39세에서 75세)였다. 술전 및 술중에 IABP를 시행한 환자의 수술사망율은 각각 33.3, 42.9%였으며 술후 IABP를 시행한 환자는 모두 생존하였다. IABP이탈율은 술전의 경우 66.77%. 술중의 경우 85.7%였으며 술후에 시행한 IABP는 모두 이탈 가능하였다. 결론적으로 IABP는 심근 손상이 가역적인 시기에 적용할 경우, 수술전후 어느시기에나 안전하게 사용가능하며 수술전후의 혈류역학적 불안정, 체외순환기 이탈 및 저심박출증의 치료에 도움을 줄 수 있다고 판단된다.

Intra-aortic balloon pump [IABP] was applied to 12 patients between July, 1987, and September, 1990. The 12 patients included 8 who were assisted with IABP intraoperatively; 4 patients used IABP postoperatively. 8 patients could not be withdrawn from cardiopulmonary bypass [CPB], but 6 of them [75%] were able to separate from CPB with IABP. They all were withdrawn from the balloon. Four [50%] of them are hospital survivors, and alive at the time of this report. 4 additional patients were assisted with IABP, postoperatively. 2 of them [50Yo] were withdrawn from the balloon but died. The overall survival and balloon weaning rates are 33.3% [4/12] % 66.7% [8/12], respectively. IABP was most effective when applied early to patients who had transient and reversible injury to the myocardium.

From July 1986 to June 1987, five patients were underwent IABP [intra aortic balloon pulsation] because of sever left heart failure in spite of maximum medication. These patients were reviewed as prophylactic IABP [1 patient], During operation [3 patients] and postoperative IABP [1 patients]. All patients were showed stable hemodynamic status with improved LV function during and after IABP. there was no IABP related complication or mortality. Advanced disease needs more effective methods of mechanical circulatory assistance and heart replacement.

Background: We aimed to investigate the preoperative, operative, and postoperative factors affecting intra-aortic balloon pump (IABP) insertion in patients undergoing isolated on-pump coronary artery bypass grafting (CABG). We also investigated factors affecting morbidity, mortality, and survival in patients with IABP support. Methods: Between January 2002 and December 2009, 1,657 patients underwent isolated CABG in Izmir Katip Celebi University Ataturk Training and Research Hospital. The number of patients requiring support with IABP was 134 (8.1%). Results: In a multivariate logistic regression analysis, prolonged cardiopulmonary bypass time and prolonged operation time were independent predictive factors of IABP insertion. The postoperative mortality rate was 35.8% and 1% in patients with and without IABP support, respectively (p=0.000). Postoperative renal insufficiency, prolonged ventilatory support, and postoperative atrial fibrillation were independent predictive factors of postoperative mortality in patients with IABP support. The mean follow-up time was $38.55{\pm}22.70$ months and $48.78{\pm}25.20$ months in patients with and without IABP support, respectively. The follow-up mortality rate was 3% (n=4) and 5.3% (n=78) in patients with and without IABP support, respectively. Conclusion: The patients with IABP support had a higher postoperative mortality rate and a longer length of intensive care unit and hospital stay. The mid-term survival was good for patients surviving the early postoperative period.

대동맥내 풍선 펌프는 그 혈류역학적 효용성이 널리 알려져 있으나 자체의 합병증도 가지고 있는 것이 사실이다. 적응증에 의거한 적절한 사용만이 환자에게 최대한의 도움을 주고 합병증을 줄이는 방법이다. 대상 및 방법： 총 100명의 성인 개심술 환자 중 인공 심폐기 이탈을 위해 IABP를 사용한 21명(남 10 여 11)의 환자를 대상으로 하였다. 이들 중 18명(85.7%)은 허혈성 심장질환 환자였다. 대상 환자들의 수술 전 조건, 혈류역학적 변수, 수술 후 상태, IABP 합병증 등을 분석 하였다. 결과： 21명 중 19명(90.5%)의 환자가 성공적으로 IABP에서 이탈하였다. 수술 후 30일 이내에 사망한 환자는 2명(9.5%)이었다. IABP 사용 시간은 40.7$\pm$24.3시간이었으며, 수술을 요하는 IABP관련 혈관 합병증은 2예(9.5%)였다. 결론： IABP는 개심술 후 심인성쇽의 치료에 효과적으로 사용할 수 있는 치료 방법이며 그 합병증 빈도가 낮으므로 안전하게 사용될 수 있는 방법이다.

From June 1989 to July 1992, we used centrifugal Biomedicus pump[CBP] in 20 patients In 9 cases, CBP was used as ventricular assistance after heart surgery for those who could not be weaned off bypass even with intra-aortic balloon counter-pulsation and with maximal inotropic support In 8 patients, CBP was used as partial left heart bypass during repair of aortic aneurysms or congenital aortic anomalies. And in 3 patients, CBP was used as vena caval bypass during resection of renal cell carcinoma with tumor extension into the inferior vena cava. In 2 of 9 patients with ventricular assistance, they were weaned off the device successfully after 16 hours and 7 days respectively. But the patients died of intracranial hemorrhage and sepsis, 7 and 29 days after weaning from cardiac support, respectively. In all the patients who underwent aortic of vena caval surgery using CBP as shunt, there were no complications such as postoperative bleeding necessitating reoperation, renal failure or neurologic sequelae. In conclusion, the centrifugal type of ventricular assistance may be potentially life saving treatment modality in patients with severe postoperative low cardiac output syndrome. The CBP can be safely employed for resection of renal cell carcinoma with vena caval tumor extension and for repair of aortic aneurysms.

Postoperative coronary arterial spasm is a rare but potentially fatal complication. A 51-year-old male patient with a history of a reactive ergonovine stress test coronary angiogram developed refractory coronary artery spasm after undergoing minimally invasive direct coronary artery bypass grafting of the left anterior descending coronary artery. The patient was successfully managed with rapid implementation of intra-aortic balloon-pump counter pulsation and extracorporeal membrane oxygenation.

Mechanical valve thrombosis is a serious and potential lethal complication unless early diagnosis & prompt therapy are made. We have been experienced 3 cases of valve thrombosis. From Aug. 1988 to July 1994, reoperations of mitral valve replacement [MVR] with mechanical prostheses [all mitral] were performed in three patients[2 men, 1 woman] due to valve thromboses. All three patients were diagnosed by means of cineradiography. Preoperative status of was shock status and he was applied intra-aortic balloon pump [IABP]. All three cases of prosthetic valve failure [PVF] were treated by Redo-MVR. Time intervals of reoperations were 5months, 40months, and 35months, respectively. In all cases, valve thromboses were excised successfully. Cineradiography provided an accurate diagnosis in all cases, which was utilized as safe, reliable & noninvasive imaging modalities. There were no operative death & complication. All three patients were fully recovered and returned to their employements, and active lives.

We present the case of a 38-year-old woman admitted to our outpatient clinic with accelerating back pain and fatigue following a kick to her back by her husband. Upon arrival, we detected ST segment elevation in the D1, aVL, and V2 leads and accelerated idioventricular rhythm. She had pallor and hypotension consistent with cardiogenic shock. We immediately performed coronary angiography and found a long dissection starting from the mid-left main coronary artery and progressing into the mid-left anterior descending (LAD) and circumflex arteries. She was then transferred to the operating room for surgery. A saphenous vein was grafted to the distal LAD. Since the patient was hypotensive under noradrenaline and dopamine infusions, she was transferred to the cardiovascular surgery intensive care unit on an extracorporeal membrane oxygenator and intra-aortic balloon pump. During follow-up, her blood pressure remained low, at approximately 60/40 mmHg, despite aggressive inotropic and mechanical support. On the second postoperative day, asystole and cardiovascular arrest quickly developed, and despite aggressive cardiopulmonary resuscitation, she died.
