We report a case of Tangier disease with Leriche syndrome and bleeding tendency. In this male patient, nasal hemorrhage had been observed frequently throughout childhood. At 46 years old, he experienced effort angina, and coronary angiography demonstrated 75% stenosis in the right coronary artery. Orange-colored tonsils, mild hepatosplenomegaly and very low levels of serum high-density lipoprotein cholesterol (HDL-C) were observed, and the patient was diagnosed with Tangier disease. At 52 years old, effort angina recurred. Coronary angiography revealed 75% stenosis of the left main trunk, left anterior descending, and right coronary arteries. Stenosis of the brachiocephalic and right common iliac arteries was also recorded. Stents were implanted, and coronary artery bypass surgery was performed. At 53 years old, 15 months after surgery, the patient reported intermittent claudication, coldness of feet, and impotence. Aortic angiography showed progression of the stenosis at the bifurcation of the common iliac artery. The patient was diagnosed with Leriche syndrome, and aorta-left external iliac artery graft bypass surgery was performed. After surgery, oozing from subcutaneous tissue and leaking from the anastomotic region were observed. Additional analysis revealed two single-nucleotide polymorphisms (V825I and N935T) in the ATP-binding cassette transporter A1 (ABCA1) gene, and accumulation of small dense low-density lipoprotein together with low levels of HDL-C. In Tangier disease, HDL-C is markedly decreased because of ABCA1 deficiency. However, this is the first reported case to exhibit extensive atherosclerosis and bleeding tendency. This patient had atypical extensive and multiple atherosclerotic lesions, accompanied by Leriche syndrome and uncontrollable bleeding.

A comparative study between left heart bypass with a centrifugal (BioMedicus) pump and with a temporary external shunt was performed to assess the efficacy of distal organ perfusion in the surgical treatment of 31 patients with aneurysm of the descending thoracic aorta. Eighteen patients were supported with a centrifugal pump, and the remaining 13 were supported by temporary shunt with either a Gott shunt or a Dacron graft. Heparinless bypass with a centrifugal pump provided a significant decrease of intraoperative blood loss and blood transfusion by the combined application of Cell-Saver. The pressure difference between upper and lower extremities decreased (p < 0.05) in the centrifugal pump group even with aortic cross-clamping, and the urine output increased during operation. Among 13 patients supported with the temporary shunt, 3 had postoperative renal failure, and 2 died of it. All patients with a centrifugal pump survived without any complications. It could be concluded that the left heart bypass with a centrifugal (BioMedicus) pump was safe and was favorable for support of the distal circulation during aortic cross-clamping and to prevent ischemic complications such as renal failure and spinal cord injury.

A 59-year-old man was admitted with general fatigue, an epigastric mass, and remittent fever. Radiological examinations disclosed a huge solid-to-cystic mass in the right lobe of the liver, and the mass severely compressed the right diaphragm, the inferior vena cava, and the right atrium. In addition, the patient suffered from chronic hepatitis; however, the serum alpha-fetoprotein, carcinoembryonic antigen, and PIVKA II levels were all within the normal ranges. The serum C-reactive protein level was 7.71mg/dl. With a clinical diagnosis of a malignant hepatic tumor invading the right diaphragm, surgery was performed. The tumor originated from segments IV and VII of the liver, was well defined, and grew extrahepatically. The tumor was resected using an ultrasonic cavitational aspirator together with the infiltrated right diaphragm. The resected tumor measured 23 x 13 x 23cm in size and weighed 3,700 g. Histologically, the tumor was found to consist of hepatocellular carcinomatous component and sarcomatous component. In the sarcomatous component, spindle-shaped cells which were positive for the immunohistochemical localization of vimentin, alpha-smooth muscle actin, and keratin were identified. The postoperative course was uneventful. The value of the serum C-reactive protein returned to within the normal range, and the patient became afebrile. The patient received a postoperative combination chemotherapy (etoposide, epirubicin, and cisplatin), and remains well with no signs of recurrence 12 months after the operation.

Purpose: The outcome of patients who underwent radical resection of renal cell carcinoma extending into the vena cava was retrospectively analyzed, and risk factors for long-term survival were investigated. Methods: From 1983 to 1999, 33 patients who had renal cell carcinoma with inferior vena caval tumor extension underwent 34 surgical procedures. There were 27 men and six women with an average age of 60.1 years. Twenty-two cases (64.7%) were classified as stage III (T1-2 N1 M0 or T3 N0-1 M0), and 12 cases (35.3%) as stage IV (T4 or N2-3 or M1). Coexistent lung metastasis was found in seven cases (20.6%). The tumor thrombi invaded into the inferior vena cava below the hepatic hilum in 19 cases, below the orifice of hepatic veins in 12, and above the diaphragm in 3. Cardiopulmonary bypass graft was applied in 13 cases (38.2%). Inferior vena cava was reconstructed by direct suture (n = 19), polytetrafluoroethylene patch angioplasty (n = 13), or graft replacement (n = 2). Results: Two patients died during the early postoperative period because of retrohepatic caval injury and intraoperative pulmonary embolism. Late death occurred in 16 patients; the causes of death were tumor recurrence in 15 and acute pulmonary embolism as a result of graft thrombosis in 1. Overall 1-, 5-, and 10-year survival rates were 70%, 44%, and 26.4%, respectively. One- and 5-year survival rates were 81.3% and 52.9% for stage III and 50% and 31.2% for stage IV; a statistically significant correlation was found between surgical staging and survival ( P =.049). Patients without lymph node metastasis had a significant survival advantage over those with lymph node metastasis ( P =.022). There was no significant difference in survival on the basis of the presence or absence of synchronous lung metastasis ( P =.291). The degree of local extension of the tumor or the level of tumor thrombus did not tend to influence survival. Conclusions: Surgical prognosis in patients with renal cell carcinoma extending into the vena cava was determined by the staging of the tumor, especially lymph node status, and not by the level of tumor thrombus or the presence of concurrent lung metastasis. The use of cardiopulmonary bypass graft is recommended for the resection of tumor thrombus extending over the diaphragm. (J Vasc Surg 2001;33:789-96.)

A retrospective review of the perioperative management of patients with cardiovascular surgical disorders and cholelithiasis was conducted, and the surgical strategies employed are discussed. Between 1988 and 1998, 18 patients having cardiovascular surgical disorders underwent cholecystectomy. These patients were divided into three groups: group I, given a one-stage operation (n = 9); group II, given a two-stage operation (n = 3); and group III, given cholecystectomy during follow-up after cardiovascular surgery (n = 6). In group I, a median laparotomy was adopted for patients with an abdominal aortic aneurysm (AAA) to allow both disorders to be treated through the same incision, whereas a right subcostal approach was employed to separate the incisions for patients who underwent cardiac operations. In group II, one patient underwent cholecystectomy before cardiac surgery, and two patients underwent cholecystectomy for postoperative cholecystitis after cardiovascular operations. One patient from group II and all from group III were on preoperative anticoagulant therapy, two of whom underwent laparoscopic cholecystectomy. No fatal complications such as prosthetic infection, intraperitoneal hemorrhage, or cerebral attack were encountered. In conclusion, we consider that performing cholecystectomy during AAA repair may be safe and prevents the risk of postoperative cholecystitis; it is preferable to treat cholelithiasis coexisting with cardiac disorders concomitantly with or before cardiac operations; and laparoscopic cholecystectomy can be safely performed under anticoagulant therapy.

Between January 1992 and December 1997, we employed percutaneous cardiopulmonary support (PCPS) using a centrifugal pump in 25 patients. In 21 of them, PCPS was used postcardiotomy. These patients could not be weaned from cardiopulmonary bypass due to profound ventricular failure. As for the other 4 patients, PCPS was used preoperatively for profound cardiogenic shock, a thrombosed valve, a stuck valve, and pulmonary embolization. Nine patients (43%) were weaned from PCPS (Group 1), and 3 (14%) were discharged from the hospital. The other 12 patients (57%) had perioperative extensive myocardial infarction and could not be weaned (Group 2). The causes of death were bleeding and multiple organ failure (MOF) associated with ventricular failure. The reasons for MOF were perioperative massive transfusion and hepatic congestion caused by sustained ventricular failure. To increase the survival rate, complete hemostasis and prevention of increased central venous pressure by early use of PCPS are necessary.

Recovery without residual neurological damage after cardiac arrest with temporary cerebral ischemia is rare. Therefore, it is most important that every effort is made to prevent brain damage occurring immediately after successful cardiopulmonary resuscitation. We report herein the cases of three patients who suffered either cardiogenic or hypovolemic shock and were resuscitated by a cardiopulmonary support system followed by mild hypothermia. All three patients recovered completely without any neurologic damage. The outcomes of these three patients demonstrated that mild hypothermia may be important for cerebral preservation after cardiopulmonary resuscitation.

Two cases of von Recklinghausen's disease developing hemorrhagic shock by intratumorous bleeding were successfully treated by arterial embolization followed by surgical resection. Case 1 involved a 38-year-old woman who had been having a subcutaneous tumor with the size of infant's head in the left hip for several years. The patient was transferred to th hospital because of abrupt pain and enlargement of the tumor (27×18×15cm) leading to hemorrhagic shock. Case 2 involved a 53-year-old man who was emergently admitted to the hospital because of an enlarging huge hematoma (30×37×35cm) in the right shoulder to back. The systolic pressure was 40mmHg and the patient was in a shock state. Both cases had no epidode of trauma before admission. Emergency arterial embolization was performed in both cases to achieve the sufficient hemostsis and prevent the progression of hemorrhagic shock. Thereafter, one and two weeks later, elective resection of the neurofibroma with hematoma was successfully performed in both cases. It has been reported that acute hemorrhage is a rare complication for elephantiasis neurofibroma, but easily develops deep shock and becomes lethal. And the emergent operation is unavoidable of massive amount of intraoperative bleeding. We emphasize that combined treatment of preoperative arterial embolization with surgical resection should be recommended to treat this fatal complication of von Reclinghausen's disease.

There are three ways to approach and resect the caudate lobe of the liver, that is; and isolated caudate lobectomy, a combined resection of the liver overlying the caudate lobe, and a transhepatic anterior approach by splitting parenchyma of the liver.We had two patients with neoplasms originating in the caudate lobe who underwent a complete caudate lobectomy. Both patients have been doing well without liver dysfunction. Although after the transhepatic anterior approach we anticipated an adverse effect from splitting the parenchyma of the liver, the postoperative course was uneventful and similar to that of the right side approach.

This paper describes a case of primary adenocarcinoma of the appendix in a 53-year-old woman, together with an analysis of 132 cases seen in the Japanese literature from 1985 to 1995. The patient was admitted to the hospital because of right lower quadrant pain lasting for about one month when the pain was repeatedly intensified and relieved. With abdominal ultrasonography and computed tomography, a preoperative diagnosis of ileocecal abscess associated with appendicitis was made. An ileocecal resection including a two-third portion of the oral side ascending colon was performed. Histologically it was adenocarcinoma of the appendix. In a review of 132 cases reported in Japan in a recent decade, the chief complaints were unspecific such as right lower quadrant pain in 40%, abdominal mass in 14% and genitourinary complaint in 11% of the cases. Twenty-one patients had no symptoms caused by the appendiceal lesion. Preoperative diagnosis was made as acute appendicitis in 26%, cecal cancer in 6%, cancer of the ascending colon in 4%, ileocecal mass in 3% and cancer of the sigmoid colon in 2%, whereas cancer or tumor of the appendix in 20%. Another review of Japanese cases before 1987 shows that the correct preoperative diagnosis was made in much fewer cases than those of the last 10 years. In our review the number of the patients diagnosed as appendiceal carcinoma or appendiceal tumor, who preoperatively underwent ultrasonography, computed tomography, barium enema, or colon fiberscopy, was double of those whose preoperative diagnoses were incorrect. This fact shows that these methods should be tried to improve the preoperative correct diagnosing rate.

Deep hypothermic retrograde cerebral perfusion (RCP) has recently been the focus of interest as a simple new technique of brain protection during the operation for thoracic aneurysms. During the period from January 1991 to July 1994, 21 consecutive patients underwent operations on the various portions of the thoracic aorta with the use of deep hypothermic RCP. There were 10 men and 11 women, ages ranging from twenty-eight to seventy-eight (mean 61.4) years old. There were 9 cases with true aortic aneurysm, and 12 with dissecting aneurysm. In 8 patients (38.1%) the procedures were done on an emergency basis for ruptured/impending ruptured aneurysms or acute dissecting aneurysms. Four patients died before the adequate assessment of their neurologic function. One patient had a cerebral infarction probably due to dissection of the left common carotid artery. The remaining 16 patients showed clear consciousness and had no serious neuro logic complications postoperatively. Total perfusion time averaged 297 ± 110 minutes (ranging from 162 to 548 minutes). Rectal temperatures were 20.1 ± 1.4°C (ranging from 18.0 to 22.5°C). RCP time averaged 51.3 ± 13.9 minutes (ranging from twenty-seven to eighty minutes). Blood gas analysis of the returned blood sampled from the left common carotid artery or the innominate artery and the ophthalmoscopic findings demonstrated the insufficiency of blood and oxygen supply to the brain during RCP. Therefore, RCP time should be shortened and pharmacologic cerebral protection is recommended to reduce neurologic complications during operations on the thoracic aorta using RCP.

Primary venous aneurysms are infrequently noted. We present a case of a venous aneurysm arising in the lesser saphenous vein. A previously healthy 76-year-old woman was seen at the hospital because of a soft mass at the left popliteal fossa. On the ultrasonography and ascending venography, the mass was diagnosed as venous aneurysm (saccular type) at the left lesser saphenous vein. The mass was saccessfully resected and vascular reconstruction by the end to end anastmosis between the inflow and outflow veins was done. Since venous aneurysm can cause thromboembolism, aggressive resection is recommended. Vascular reconstruction without vascular prosthesis is an ideal procedure to prevent the venous congestion.

The number of patients being encountered with abdominal aortic aneurysm (AAA) and inguinal hernia is increasing. We describe herein a technique of performing a concomitant one-stage operation for both disorder. After conventional transperitoneal AAA repair, transabdominal preperitoneal hernia repair is carried out through the same incision using a prosthesis made from the same material as the graft used for AAA. The maneuver is similar to that of laparoscopic hernioplasty. We employed this technique in the treatment of four patients, none of whom developed any complications such as infection or recurrence of the inguinal hernia. Thus, we conclude that this one-stage operation for AAA and inguinal hernia may bring physical and economic benefits to patients who have both diseases concomitantly.

We report herein the rare case of a 53-year-old woman who developed cardiogenic shock due to an acute left atrial thrombus following replacement of the mitral valve. A definitive diagnosis was not able to be made using precordial echocardiography because of the broad, flat shape of the thrombus; however, transesophageal echocardiography imaged the thrombus in detail. The patient was initially stabilized by percutaneous cardiopulmonary support after which a thrombectomy was successfully performed.

Three cases of adults who required a mitral valve replacement (MVR) following repair of an atrioventricular (AV) canal are presented herein. In adult patients with an AV canal, the deformity of the mitral valve is sometimes too advanced for adequate repair, and therefore, residual mitral regurgitation frequently causes intractable cardiac failure despite appropriate medical management. Thus, for adults with an AV canal associated with severe valvular deformities, MVR should be considered from the initial operation to obtain a significantly better outcome.

A saccular aneurysm in the right-sided aortic arch with aberrant left subclavian artery is an uncommon disease, and surgical treatment is complicated. Three patients with Edwards type III-B right aortic arch and enlargement of the Kommerell's diverticulum underwent operations. Right thoracotomy was the preferred approach for this lesion and partial cardiopulmonary bypass is a safe and simple procedure when the aortic arch has mild atherosclerosis.

The authors describe a 47-year-old woman with intravenous leiomyomatosis (IVL) extending into the right ventricular cavity. This rare entity is a neoplasm originating from smooth muscle of the uterus, with vermiform extensions into the inferior vena cava. The patient underwent a one-stage operation under simultaneous sternotomy and laparo tomy, and radical excision of the tumor was successfully achieved with use of normoth ermic cardiopulmonary bypass. Although this tumor is histologically benign, it sometimes extends into the cardiac cavity and causes sudden death due to incarceration into the atri oventricular orifice. Moreover, recurrence or lung metastasis of IVL has been reported. The authors recommend a one stage-radical resection of the tumor or a two-staged operation within a short interval. In the literature, 24 surgical cases of the intravenous leiomyomatosis with intracardiac extension have been reported. The diagnosis and surgical treatment of this tumor are reviewed and discussed.

We report herein the case of a 69-year-old man who underwent laparoscopic adrenalectomy for a solitary adrenal metastasis 10 months after a left lower lobectomy for T2N1M0 lung cancer. A 30 x 20 mm tumor was found in the left adrenal gland, and dissected using an ultrasonically activated scalpel. Histological examination revealed metastatic squamous cell carcinoma. The patient recovered uneventfully and his condition is now stable 18 months after the second operation, with no evidence of local recurrence or metastatic disease. Although laparoscopic resection for malignant adrenal tumors is still controversial, we consider that laparoscopic adrenalectomy may be an optional treatment for metastatic adrenal tumors, provided the tumor is solitary, small in size, and well-localized. To our knowledge, only 14 cases of laparoscopic adrenalectomy for malignant tumors have been reported to date; however, this is the first case of successful laparoscopic adrenalectomy for a metastasis from lung cancer.

Reoperation for valvular heart disease has been associated with a higher operative mortality than primary operations, especially in patients who had multiple prior operations. We have analyzed the 226 consecutive patients who underwent valve replacement. These involved 163 primary operations, 52 first reoperation, and 11 second/third reoperations. Preoperative left ventricular dysfunction was more severe, and operation time and cardiopulmonary bypass time were significantly greater according to the number of operations, associated with a greater amount of intraoperative blood loss. The operative mortality after a second/third reoperation was 27.3%, which was significantly higher than that after primary operation (6.7%) (p < 0.05), and that after first reoperation (5.8%) (p < 0.05). Seven (64%) patients who underwent a second/third reoperation had poor preoperative left ventricular function (%FS < 25%), and 5 (71%) of these required postoperative mechanical supports, and 3 (60%) of the 5 patients died of low output syndrome. We have found that poor preoperative left ventricular function and the duration on cardiopulmonary bypass, but not the number of reoperation were correlated with operative mortality. Continued efforts should be directed to decrease the mortality for multiple reoperative valve surgery.

The therapeutic approach to a patient who has an abdominal aortic aneurysm (AAA) and an intraabdominal nonvascular surgical disorder simultaneously remains controversial. To establish guidelines for the management of those patients, a retrospective review of patients who had concomitant AAA and intraabdominal nonvascular surgical disorders was undertaken. During the period January 1988 to December 1997 a series of 162 patients underwent surgical repairs of AAA in our hospital. Among them 16 patients (9.9%) had several kinds of intraabdominal nonvascular surgical disorders, and 13 underwent one-stage operation for both diseases. That is, cholelithiasis coexisted in five patients, inguinal hernia in four, gastric cancer in two, and retroperitoneal tumor and renal tumor in one each. All AAAs were the infrarenal type, and there were no inflammatory or ruptured aneurysms. In cases of cholelithiasis coexistent with AAA, aneurysmectomy was performed first. After tight closure of the retroperitoneum, cholecystectomy was done. In cases of cholelithiasis coexistent with AAA, aneurysmectomy was performed first. After tight closure of the retroperitoneum, cholecystectomy was done. In cases of inguinal hernia coexistent with AAA, the AAA was first replaced with a prosthetic vascular graft and a residual piece of the graft was used as a patch for hernioplasty. This procedure was similar to laparoscopic hernioplasty. In two cases of gastric cancer concomitant with AAA, the AAA was first replaced. Subtotal gastrectomy with D2 lymphatic dissection was done after tight closure of the retroperitoneum. A drain was inserted into the epiploic foramen to detect anastomotic leakage. A retroperitoneal tumor coexisting with AAA was dissected and resected en bloc with the aneurysmal wall because the tumor firmly adhered to the aneurysm. The abdominal aorta was then replaced with a prosthetic graft. In a case of renal tumor concomitant with AAA, nephrectomy was done first to perform a complete lymphatic dissection around the renal artery. Then AAA repair was performed with a conventional procedure. There were no fatal complications, such as pneumonitis, hemorrhage, anastomotic leakage, or graft infection. All 13 patients were discharged from our hospital and are currently free from recurrence of malignancy or hernia. In summary, properly selected one-stage operations for intraabdominal nonvascular surgical disorders and AAA may be safe and bring physical and economic benefit to the patient.

Aggressive surgical treatment in renal cell carcinoma is still controversial. The aim of this paper is to assess inferior vena caval (IVC) reconstruction for suprahepatic vena caval renal cell carcinoma (RCC) tumor thrombus. Twelve patients with suprahepatic vena caval thrombus from renal cell carcinoma who underwent surgical repair with cardiopulmonary bypass were evaluated. The vena caval defect was reconstructed by direct suture, patch repair, or graft replacement. Of 12 patients undergoing partial cardiopulmonary bypass, tumor thrombus extended to the junction of the hepatic vein in three patients and to the right atrium in one. Tumor thrombus was removed manually or with balloon catheter. Tumor thrombus in the right atrium was removed during electrical ventricular fibrillation. Repair of the IVC was performed by direct suture of the IVC wall in two patients, patch repair with expanded polytetrafluoroethylene (EPTFE) graft in seven, and graft replacement with an EPTFE graft in three. There were no operative deaths and the only postoperative complication was one patient death from pulmonary emboli. The four patients with nonlocalized disease died within 2 years, but four patients lived for more than 3 years postoperatively. Survival was 37.5% at 3 years and 18.8% at 5 years by the Kaplan-Meier's method. Conclusions: (1) Partial cardiopulmonary bypass is useful for the control of bleeding when tumor thrombus in the IVC extends to the junction of the hepatic vein. (2) Nephrectomy with tumor thrombectomy of the IVC is valuable, and long-term survival is possible in patients without distant metastases or regional lymph node metastases.

Medically refracted patent ductus arteriosus (PDA) in an extremely low birth weight (ELBW) preterm (gestation 24 weeks 2 days) infant was successfully ligated under general anesthesia in the neonatal intensive care unit (NICU). Pharmacological agents are more effective to close PDA in preterm infants than in full-term infants, although within 48 h three doses of indomethacin were not sufficient to close PDA in this case. At the age of 69 h the infant developed severe symptoms including bradycardia, systemic hypotension, pulmonary hypertension, diastolic steal (reverse distal aorta flow velocity), and anuria. A PDA ligation was thus performed surgically at 72 h of age. General anesthesia and surgical stress were tolerated by this 531 g infant. Postoperatively all symptoms improved dramatically and the general conditions were stable. On the 38th day the endotracheal tube was extubated and on the 50th day nasogastric milk feeding was started. The oxygen supply was weaned on the 78th day. Growth and development until 6 months were within the normal range of very low birth weight infants. A surgical ligation as early as possible in medically refracted PDA in an ELBW infant is thus considered to be a safe and effective treatment. It prevents the development of further complications of cardiopulmonary vascular problems. Color Doppler echocardiography can reliably measure the PDA size, flow velocity, and hemodynamic changes of persistent PDA, even in tiny infants.

Background . Repair of distal aortic arch aneurysms is difficult to accomplish through a median sternotomy or left thoracotomy, and stroke and respiratory disorders often become lethal complications with the use of circulatory arrest. We investigated the use of retrograde cerebral perfusion with a posterolateral thoracotomy in the repair of distal arch aneurysms. Methods . Thirty-eight patients underwent repair of a distal arch aneurysm. They were divided into three groups according to the method of surgical repair used. Sixteen patients (group I) underwent proximal anastomosis of the graft with the use of an aortic cross-clamp. Eight patients (group II) underwent open proximal anastomosis with the use of retrograde cerebral perfusion (oxygenated blood perfusion through a superior vena cava cannula) and a median sternotomy and anterolateral thoracotomy. Fourteen patients (group III) also underwent open anastomosis with the use of retrograde cerebral perfusion (cerebral perfusion through blood returned to the right atrium with the patient in the Trendelenburg position) and a posterolateral thoracotomy. Results . The operative mortality rate in group I was 25.0%; 4 of 16 patients died of stroke, myocardial infarction, and intestinal necrosis. In group II, 3 of 8 patients (37.5%) died of respiratory failure and aortic dissection. In group III, only 1 of 14 patients (7.1%) died, as a result of heart failure. Conclusions . The use of retrograde cerebral perfusion with a posterolateral thoracotomy is an alternative method that minimizes the risk of stroke and respiratory failure during distal aortic arch operations.

From 1984 to 1996, four patients with transvenous intracardiac tumor extension underwent operations in the Kobe University Hospital. The primary tumors of two were intravenous leiomyomatoses originating from the uterus; a third patient had invasive thymoma, and the fourth patient had clear cell sarcoma of the kidney. In 1985, one patient had a curative, staged resection. One-stage operations were carried out in three patients, and all intracardiac tumors were successfully resected en bloc with the primary tumors under conditions of electrical ventricular fibrillation and mild hypothermia. Combined venous reconstructions were necessary for en bloc resection in three cases. Two patients with malignancy received postoperative chemoradiotherapy, and all four patients were discharged uneventfully from our hospital. We consider radical resection with curative intent only for patients with tumors extending into the heart. In these cases, a one-stage operation is preferable, and electrical ventricular fibrillation with mild hypothermia is a recommended method of circulatory assist because of its simplicity.

Background . In patients with aortic dissection, a patent distal false lumen at long-term follow-up leads to complications. We investigated the feasibility of performing an open distal anastomosis using retrograde cerebral perfusion. Methods . Over a 10-year period, 41 patients with acute type A aortic dissection underwent 43 surgical repairs. In 1991, an open distal anastomosis using retrograde cerebral perfusion (group 2) was introduced to replace the standard aortic cross-clamp method (group 1). The mean retrograde cerebral perfusion time was 47.3 minutes (range, 22 to 67 minutes), and there were no neurologic sequelae in surviving patients. Results . The operative mortality rate was 18.5% in group 1 and 18.7% in group 2. At long-term follow-up, dilatation of the false lumen (more than 50 mm in diameter) occurred in 9 of 18 patients (50%) in group 1, and 2 patients died of aortic rupture. There were no deaths in group 2, and dilatation of the distal false lumen occurred in only 15.4% of patients ( p Conclusions . The use of retrograde cerebral perfusion in patients with acute aortic dissection provides adequate time to perform a safe, open, distal anastomosis, and could decrease significantly the rate of enlarged, patent, false lumina.

To determine the permissible range of the St. Jude Medical 19 mm valve (SJM19) as an aortic prosthesis, transvalvular maximal pressure gradient (maxPG) and postoperative reduction of left ventricular (LV) hypertrophy were examined in 21 patients (body surface area [BSA] 1.28-1.56 m2, mean 1.42 m2). Doppler echocardiographically measured maxPG at rest was 31 ±16 mmHg, which showed no significant difference from the differences in patients' diseases (aortic regurgitation=AR or stenosis=AS), or BSA. The maxPG, also measured during dobutamine administration when they were less than 40 mmHg at rest, increased significantly from 21 ± 11 mmHg to 32.1 ± 15 mmHg, having no differences from the differences in diseases or BSA. Reduction of LV hypertrophy was achieved postoperatively (mean postoperative period of ten months), with the reduction rates of 26 ± 19% in LV mass and 21 ± 15% in LV cross-sectional area. No significant differences were found between the reduction rates and the differences in the patients' diseases or BSA. These results indicate that, following the implantation of SJM19, LV hypertrophy was reduced in patients with AR as well as with AS, when their BSA values were less than 1.6 m2. However, limited use is recommended because the increase in pressure gradient during exercise cannot be ignored.

Cytosolic calcium in the myocardium is rapidly accumulated during ischemia and has been correlated with the attenuation of functional recovery in the myocardium. The aged myocardium is more sensitive to ischemia and accumulates significantly more cytosolic calcium than either the newborn or the mature myocardium. Modification of the age-related propensity to increased cytosolic calcium accumulation may be achieved through the use of magnesium or potassium/magnesium cardioplegia. Improved postischemic ventricular function obtained with magnesium or potassium/magnesium cardioplegia may have important implications in the reduction of myocardial morbidity and mortality.
