ABSTRACT
We report a case of arbitrary delayed surgical repair for left ventricular free wall rupture (LVFWR) after acute myocardial infarction with suspected posterior papillary muscle necrosis. The case was a 67-year-old woman who had chest and back pain in the morning, and relapsed in the evening, and was urgently transported. She had an acute lateral wall myocardial infarction on an electrocardiogram and pericardial effusion on transthoracic echocardiography (TTE). She was found to have an obstruction at the origin of the left circumflex branch on coronary angiography. TTE showed low-intensity findings on the head of the posterior papillary muscle, suggesting necrosis of the papillary muscle. For LVFWR, conservative treatment was prioritized and IABP (intra-aortic balloon pumping) management was performed for the purpose of reducing after load because there was concern about papillary muscle rupture (PMR) due to cardiac manipulation and because it was an oozing type and did not disrupt respiratory of circulatory dynamics. On the 7th day after the onset, TTE showed improvement in echo-luminance of the posterior papillary muscle head and gradual increase in pericardial fluid, and a non-suture procedure was performed. She withdrew from the IABP on the third day after surgery and was discharged home on the 12th day.
ABSTRACT
The U-40 generation of surgeons are practicing through trial and error, and form various careers. At the 51st Annual Meeting of the Japanese Society of Cardiovascular Surgery, U-40 Special Project, we looked back on the U-40 generation and more senior doctors to see what kind of future visions, problems and careers they have had. We conducted a questionnaire for the purpose of visualizing the future prospects of the U-40 generation. In this article, we report the results.
ABSTRACT
In the U-40 column, we conducted a questionnaire survey of the U-40 generation on the theme of the specialist system for cardiovascular surgery and reported on the present condition and problems in obtaining certification. With the introduction of a new system, off the job training and participatory training using extracorporeal circulation techniques were newly mandated. In this article, we report the results and discussion of the questionnaire survey regarding the present condition of extracorporeal circulation training for the U-40 generation and the pros and cons of training programs.
ABSTRACT
Herein, we report a rare case of a pseudoaneurysm at the anastomotic site of the bicarotid trunk after thoracic aortic graft replacement. A 53-year-old man with Marfan syndrome underwent a three-stage operation involving aortic root reimplantation and ascending aortic replacement ; aortic valve replacement and total arch replacement ; and descending aortic replacement performed for type A dissection combined with an aberrant right subclavian artery. Two years after total arch replacement, the patient presented with hoarseness and a computed tomography scan revealed an anastomotic pseudoaneurysm of the common trunk of the left and right carotid arteries. A right axillary artery-common carotid artery bypass was performed, with simultaneous insertion of a vascular stent graft from the left common carotid artery to the anastomotic site. Cervical bypass and stent implantation were both performed without shunting. He was discharged home without any neurological complications.
ABSTRACT
We investigated how cardiovascular surgeons get a day off.
ABSTRACT
A 58-year-old man underwent renal transplantation 26 years previously and had been treated with immunosuppressive drugs. He presented at the local hospital with backache symptoms during the waiting period prior to repair of an abdominal aortic aneurysm. Computed tomography revealed a retroperitoneal hematoma around the abdominal aortic aneurysm. He was admitted to our hospital and emergency straight graft replacement was performed. After clamping of the aorta, we performed axillo-common iliac perfusion to protect the transplanted kidney. The patient recovered without transplanted kidney dysfunction.
ABSTRACT
A 77-year-old-woman was hospitalized at our institution following the diagnosis of severe aortic and mitral stenoses. Although she had thrombocytopenia before surgery, bone marrow examination revealed no abnormality. Thrombocytopenia was thought to be caused by shear stress accompanying valvular diseases. She underwent surgery for the replacement of aortic and mitral valves and the resection of left ventricular outflow tract myocardium. Because the mitral valve involved the calcification of the annulus the valve replacement was performed after decalcification using CUSA. After surgery, she experienced a transient sick sinus syndrome ; however, the overall course was good, and the platelet counts spontaneously recovered. More than 12 months have passed since surgery, but the platelet counts remains around 110,000.
ABSTRACT
We present the case of a 53-year-old man who developed delayed-onset paraplegia after type A dissection repair. He was referred to our hospital with a diagnosis of type A dissection, for which we performed total arch replacement. Although the patient started walking on postoperative day 4, on postoperative day 5, he developed lower limb paraplegia without any precipitating episodes. Computed tomography showed that the false lumen was thrombosed in the upper descending thoracic aorta and hypoperfused in the lower descending thoracic aorta. The cerebrospinal fluid was immediately drained to maintain the spinal pressure at 14 cm H<sub>2</sub>O for four days. Although the patient began to move his legs immediately after treatment, he remained paraparetic, and was transferred to another rehabilitation hospital on postoperative day 40.
