From February 1985 to February 1993, 18 operations were performed in 17 patients for treatment of aneurysmal disease [n=12] and/or dissection of the ascending aorta [n=6]. The ages ranged from 26 to 69 years [mean 44.3 $\pm$ 11.0 years].The proposed operations include composite graft replacement of aortic valve and ascending aorta with coronary reimplantation in 11, graft replacement of ascending aorta alone in 5, aortic valve replacement and supracoronary graft replacement in 1 and ascending aorta to abdominal aorta bypass with thromboexclusion of descending aorta in one patient. Both Bentall [n=6] and Cabrol [n=5] technique were utilized for reimplantation of coronary arteries.Concomitant replacement of aortic arch and arch vessel reconstruction was necessary in two patients. Hypothermic circulatory arrest was utilized in 6 patients. Recently, four patients were managed on warm blood continuous cardioplegia via retrograde route. There were no operative deaths. No significant postoperative complications were noted. Postoperative follow up was complete in 15 patients from 1 month to 72 months. Redo operation was necessary in one patient who had suffered from distal recurrence of dissection 5 years after successful Bentall operation. The other patients are all in excellent clinical condition. From our early experience with those 17 cases, we assume that satisfactory operative result could be achieved with a variety of surgical technique including hypothermic circulatory arrest. In addition, continuous perfusion of warm blood cardioplegia via retrograde route is supposed to be beneficial in selected cases.
Recently, stent-graft insertion has been widely used along with surgery for treatment of thoracic and abdominal aortic aneurysm. However, use of stent-graft insertion is controversial in descending aortic dissection. We report here on our experience of a patient who received a stent-graft for descending aortic dissection that nearly ruptured. Based on CT findings at three months follow up, results were satisfactory.
Ventriculoperitoneal (VP) shunt is commonly and effectively used to treat hydrocephalus. Intracardiac migration of the shunt catheter is a rare complication. A 68-year-old woman underwent ventriculoperitoneal shunting for hydrocephalus secondary to subarachnoid hemorrhage due to anterior communicating artery aneurysm rupture. Two weeks after the shunt surgery, she had suffered from the abdominal pain. Plain chest x-rays, computed tomography, and echocardiography revealed the distal catheter which was in the right ventricle of the heart. We tried to remove the catheter through the internal jugular vein by fluoroscopic guidance. But, the distal catheter was kinked and knotted; therefore, we failed to withdraw the catheter. After then, we punctured the right femoral vein and pulled down the multi-knotted shunt catheter to the femoral vein using the snare catheter. Finally, we removed the knotted distal catheter via the femoral vein and a new distal catheter was placed into the peritoneal cavity. We report a case in which the distal catheter of the VP shunt migrated into the heart via the internal jugular vein. We emphasize the importance of careful and proper placement of the distal catheter during the tunneling procedure to prevent life-threatening complications.
A 34-year-old woman experienced a sudden cardiac arrest after complaining of abdominal pain. The cause of that serious event was a hidden hemorrhagic shock. On computed tomography of her pelvic area, we found that her left common iliac artery had been ruptured. No bone fractures were observed. Her angiography showed neither atherosclerosis nor an aneurysm of the artery. Because spontaneous ruptures of the common iliac artery are rare, we suspected, based on her husband's statement, that a hidden blunt trauma to the artery had occurred via an endo-vaginal route due to dildo masturbation. Unfortunately, she died without recovery, in spite of our having controlled the bleeding by using an angiographic endovascular stent-graft.
From 1968 through September 1986, the authors have experienced 34 cases of peripheral arterial surgery using various vascular grafts. Almost all patients [32] were men, and age distribution was variable according to the disease entities. There were twenty eight cases of chronic occlusive peripheral vascular disease including ASO [21], Buerger`s disease [6], Aortoenteric fistula complicating infrarenal abdominal aortic aneurysm [1], four cases of vascular trauma, one case of acute arterial embolism [1] and one case of unknown etiology. The indications of operations for chronic vascular disease was intermittent claudication in 48%, rest pain in 45%, ischemic pregangrene or gangrene in 28%, and sensory change in 10% of patients. Types of operation used were arterial bypass in 28 cases [Aortobifemoral in 5, Aortoiliac in 3, Aortofemoral in 4, Aortoiliac with Aortofemoral in 1, Femorofemoral in 1, Femoropopliteal in 8, Femoroperoneal in 2, Axillofemoral in 3 cases of patients], graft interposition in four and patch angioplasty in three cases. Thirty four prosthetic vascular grafts including Dacron, Gore-Tex, Nylon and two autogenous saphenous vein graft and patch were used for vascular reconstruction in thirty four patients. Unfortunately recently performed one vein bypass was failed immediate postoperatively due to severity of disease and poor case selection. The authors experienced five post operative complications: wound infection [1], graft infection [1], bleeding [1], great saphenous neuralgia [1], pseudoaneurysm [1]. Twenty two of thirty four patients were followed up for more than one month and their cumulative patency rate was 81% [17/22] at 1 month and, 31% [7/22] at 5 month.
Background: Thoracoabdominal aortic replacement is an extensive operation that opens both the pleural cavity and abdominal cavity, which has high mortality and morbidity rate. The authors have reported 9 cases of the thoracoabdominal aortic replacement in 2001. Since 2003 we have applied the deep hypothermic circulatory arrest to the Crawford type I and II thoracoabdominal aortic replacement. Therefore, we analysed the effect of the changes in operative techniques. Material and Method: Between 1996 and 2005, we have performed 20 cases of thoracoabdominal aortic replacement. The underlying diseases were 8 cases of atherosclerotic aneurysm with 4 cases of ruptured aneurysm and 12 cases of aortic dissection with 10 cases of a previous operations. According to Crawford classification, there were 2 cases of type I, 7 cases of type II, 1 case of type III, 7 cases of type IV, and 3 cases of type V. We compaired the results of the patients who underwent thoracoabdmoninal replacement before 2001 which already has been reported and after then. Result: Before 2001 we have performed 9 cases of thoracoabdominal replacement and 5 patients were died of the operation. All three patients with type I and II were died. There was no case of thoracoabdominal replacement between 2001 and 2002, but after 2003 we have performed 11 cases of thoracoabdominal replacement which involved 1 case of type I, 5 cases of type II, 1 case of type III, 2 cases of type IV and 2 cases of type V. There was no mortality and no fetal complications. Conclusion: The deep hypothermic circulatory arrest is a safe method of extended thoracoabdominal aortic replacement.
One hundred and seventy-four patients were treated in this Department since 1956. One hundred and fifteen patients of them were surgically treated. They were classified on the basis of the disease entity as follows; 48 case of thrombo-angiitis obliterance, 8 cases of Leriche syndrome, 12 cases of arterial embolism, 36 arterial aneurysm, 5 arterio-venous fistula, 15 arterial and venous injuries, 8 pulseless diseases, 2 coarctation of aortas, 15 varicose veins, 12 thrombophlebitis, 9 superior venacaval syndromes, 2 inferior vena caval obstructions and Raynaud's diseases. All the cases of the Burger's diseases were males, and half of them were in the fourth decades, 39 cases underwent undergone unilateral or bilateral sympathectomies. All the Leriche syndromes were males aged over fifty. Three cases out of six were suffering from diabetes mellitus. 2 cases underwent aorto-femoral bypass graft with Y-shaped dacrons. And two embolectomies were performed in 2 cases. Eight cases of arterial embolisms among 12 had mitral valvular diseases with auricular fibrillation The most common site of lodgement of emboli was femoral artery. Nine out of 14 underwent embolectomies with Fogarty catheters. There were 14 peripheral arterial aneurysms, 16 thoracic and/or abdominal aortic aneurysms, and 4 dissecting aneurysms. Most frequent cause of peripheral arterial aneurysms were external trauma. Thoracic and abdominal aortic aneurysms were non-traumatic. And four cases of the dissecting aneurysms had significant hypertension and aged over fifty. Among 5 cases of arteriovenous fistulas, 2 cases hand typical Branham's sign, and they were normalized after operation. Eight cases of pulseless disease were females and aged from three to twenty-five. Three out of them were treated surgically using dacron prosthetic grafts, but the results of the surgery were variable and not satisfactory. A case of coarctation of aorta was treated surgically with an excellent result. Fourteen out of 15 varicose veins underwent ligation of the saphenous vein system, exstirpation of the varicose veins, stripping or some combination of these methods. Two cases of superior vena caval syndromes were operated by bypass graft between the left innominate vein and the right auricle. Two cases of inferior vena caval obstructions were operated upon through right atrial route using extracorporial circulation. All the four cases of vena caval obstructions showed excellent results postoperatively. Two cases out of 12 thrombophlebitis underwent thrombectomies. One of two Raynaud's diseases was surgically treated with an excellent result.
Aortic dissection is a serious disease that mortality does not approach to zero despite of medical and surgical improvement. Recently two cases of aortic dissection were treated with good results by the two other methods. Case 1 [57-Y-0-Male]; Chief complaint was chest pain radiating to the back. Preoperatively he was controlled by Minipress, dichlotride, & sodium nitroprusside. Aortography showed DeBakey Type III aortic dissection extending from just below the Lt. subclavian artery to the proximal portion of the origin of the renal artery. Through the midline long incision Flow reversal & Thrombo-exclusion method was used, and bypass course was proximal anastomosis at the ascending aorta - through the Rt. thoracic cavity - midportion of the diaphragm - posterior to the liver, stomach, & pancreas - distal anastomosis at the abdominal aorta proximal to its bifurcation. Bypass graft was preclotted 20 mm Dacron Woven Graft, and the aortic arch between the Lt. subclavian artery & Lt. common carotid artery was divided and meticulously sutured. Control aortogram which was done at 4th postoperative month revealed obstruction of the false lumen by thrombosis, and complications were not noticed. Case 2 [53-Y-0-Male]; Chief complaint was chest pain radiating to the abdomen. DeBakey Type III aortic dissection which was similar to the case 1 was detected by the aortography, and involvement of the Lt. subclavian & common carotid arteries was suspicious. Through the Lt. posterolateral thoracotomy the Ringed Intraluminal Sutureless Graft, No. 22 mm, was inserted from just below the Lt. common carotid artery to the midportion of the descending thoracic aorta under total circulation arrest using a F-F bypass, and the Lt. subclavian artery was ligated. Postoperatively hospital course was uneventful with antihypertensive drugs, and any specific complications were not noticed.
Background: Cardiovascular (CV) disease is known as one of the major causes of death from disease worldwide. Statin therapy plays a pivotal role in atherosclerotic cardiovascular disease (ASCVD) lowering the LDL-cholesterol level effectively. The purpose of this study was to evaluate the association of the intensity of statin therapy in adult patients of Korea and the risk of ASCVD of the patient group. Methods: We used data from sample of patients from the Health Insurance Review and Assessment Service (HIRA-NPS-2018). We analyzed the patterns of prescribing statins including types of statin, statin intensity, and number of patients with ASCVD or risk of ASCVD. Results: 155,512 patients were included in the analysis, and 27,950 patients (18.0%) was over 75 years. High-intensity statin usage was increased in ASCVD patients compared with the low-intensity statin use. The OR (odds ratio) of high-intensity statin were increased in myocardial infarction patients compared with low-intensity statin use showing the highest OR; 12.40 (95% CI; 9.48-16.22). At patient groups of angina, ischemic heart disease and carotid disease, high-intensity statin prescription rate was increased compared with low-intensity statin. However, there was no statistical significance between both statin prescription rates in patients of peripheral arterial disease, abdominal aneurysm, diabetic mellitus and atherosclerosis. Conclusion: The statin prescription rate showed intensity increasing tendency according to the risk of ASCVD. More aggressive statin therapy might be beneficial for the ASCVD patients based on the recent guidelines of dyslipidemia.
Background: To evaluate the efficiency of surgical treatment in patients with cardiac valvular and arterial involvement of Behcet's syndrome. Material and Method: 12 patients underwent surgical treatment due to the valvular heart diseases and the various arterial diseases associated with Behest's syndrome over 7 years; 6 with valvular heart disease, 1 with annuloaortic ectasia, 1 with ascending aortic aneurysm, 4 with pseudoaneurysms in abdominal aorta(n=2), carotid artery(n=1), and popliteal artery(n=1). All 12 patients had received valvular replacement(n=6) and the artificial(n=5) or autologous(n=1) graft interposition. We followed the results of these surgical treatments. Result: Operations were technically successful in all 12 patients and peri-operative complication was not demonstrated. However, 10 patients had recurrences; 6 with valvular dehiscence, 3 with pseudoaneurysm at anastostomosis site, and 1 with aorto-duodenal fistula. The duration of recurrence was 1 to 55 months(mean: 15.7$\pm$ 16.2 months). 7 patients underwent the second operation and among them, 4 patients showed repeated recurrences. Overall, 5 patients died 2 to 25 months after the operation(mean: 13.6 months), because of the bleeding at the anastomosis site Five patients did not present recurrence after the first(n=2) or the second operation(n=3) and their follow up duration was 5 to 60 months(mean: 45.8$\pm$41.7 months). Five patients received immune-suppressive therapy after the first(n=2) and second operation(n=3). Three did not shown recurrence for the 13, 29 and 33 months. Conclusion: Post-operative prognosis of arterial manifestation of Behcet's syndrome was not encouraging and if possible, other treatment strategy should be considered.
