ABSTRACT

A 67-year-old man was given a diagnosis of lung cancer and thoracic aortic aneurysm (TAA). We first performed thoracic endovascular repair (TEVAR), and then right lower lobectomy for lung cancer. TEVAR shortened the operation time and yielded less operative damage. Therefore, TEVAR can be an effective choice for simultaneous surgery of TAA and lung cancer.

ABSTRACT

An 84-year-old man, who had been given a diagnosis of advanced aortoventricular block 2 years previously, underwent implantation of a pacemaker (PM) through the left subclavian vein. However, 7 months later a skin ulcer developed at the implantation site, but without any evidence of bacterial infection. Therefore, a PTFE-covered PM battery was reimplanted at the same site. Three months later, the skin ulcer recurred and he received a third implantation in the right side. However, another skin ulcer with infection developed in the right side. He was then transferred to our hospital for another PM reimplantation. We covered the battery and the entire lead with PTFE, then placed the PM lead directly into the cardiac muscle, and implanted the PM battery below the rectal muscle under general anesthesia. A patch test 4 months later revealed a positive reaction to nickel and silicon. Finally, we diagnosed pacemaker dermatitis. The patient has remained free of skin ulcers for over 1 year.

ABSTRACT

A 38-year-old man underwent surgery for impending rupture of an inflammatory celiac artery aneurysm with a maximum diameter of about 50 mm. First, an extra-anatomical bypass was performed from the iliac arteries to the celiac artery, superior mesenteric artery and bilateral renal artery using ringed ePTFE grafts. Second, the celiac artery aneurysm at the distal site was directly closed and then a stent graft was placed in the abdominal aorta to cover the orifice of the celiac artery. An endovascular stent graft treatment combined with extra-anatomical bypass is useful for the treatment of inflammatory aneurysm to avoid the various surgical complications in Behçet syndrome.

ABSTRACT

A 46-year-old man was given a diagnosis of hypertension about 20 years previously. At age 41, aortitis syndrome was diagnosed, with descending thoracic aortic aneurysm and the coarctation of abdominal aorta by CT scan. He then underwent surgery to replace the descending thoracic aortic aneurysm and right axillo-bifemoral bypass. Recently, a thoraco-abdominal aortic aneurysm was pointed out at the distal site of the graft and, he was referred to our institute. We occluded the distal end of the aneurysm using an endoluminal occlusion stent graft. Today, in most cases of aortopathy associated with aortitis syndrome, surgical replacement of the aneurysms and extra-anatomical bypass is performed. An endovascular stent graft treatment combined with extra-anatomical bypass could be useful for various aortic disorders.

ABSTRACT

A 20-year-old man suddenly complained of back pain and bilateral lower limb weakness. Computed tomography showed acute type B aortic dissection. The patent false lumen extended from distal arch to the left common iliac artery. The true lumen was severely compressed by the false lumen and both legs were ischemic. He underwent emergency fenestration of the abdominal aorta and stenting of the left iliac artery. Although the lower limbs ischemia was improved, he developed myonephropathic metabolic syndrome and received plasma exchange, continuous hemodialysis and endotoxin absorption therapy. Thirteen days after the operation, intestinal ischemia occurred and he underwent emergency bowel resection with creation of a stoma. Development of dissection to the superior mesenteric artery (SMA) and the malperfusion of SMA by severe compression of the true lumen were thought to cause intestinal ischemia.

ABSTRACT

We report a rare case of acute type A aortic dissection with paraplegia which was reversed using cerebrospinal fluid drainage (CFD). The patient was a 80-year-old man who was admitted with acute back pain and paraplegia. Computed tomographic scans showed an acute type A aortic dissection. Four hours after onset of paraplegia, CFD was initiated by inserting an intrathecal catheter at L3-L4. Cerebrospinal fluid was drained freely by gravity whenever the pressure exceeded 10cmH<sub>2</sub>O. After 32h, the neurological deficit was completely resolved. CFD can be considered a useful treatment in patients with paraplegia after acute aortic dissection.

ABSTRACT

Spinal cord ischemia is a very rare and unpredictable complication in surgery of infrarenal abdominal aortic aneurysms. A 65-year-old man who had a history of CABG (LITA-LAD, LITA-Y composite RA-OM) underwent resection of an abdominal aortic aneurysm. Postoperatively, he developed paraplegia and hypoesthesia with associated fecal incontinence. Reduction of collateral flows of patent lumbar arteries probably caused serious ischemia of the spinal cord. A standard infra-renal abdominal aorta surgery still has the risk of postoperative paraplegia, which should be incorporated in the preoperative informed consent.

ABSTRACT

To investigate the effect of nafamostat mesilate (FUT) for disseminated intravascular coagulation (DIC) after surgery using cardiopulmonary bypass, we studied DIC scores and parameters of coagulation and fibrinolysis in the DIC cases. Although 12 patients developed DIC, the platelet counts improved by administration of FUT apart from one complicated by sepsis. The DIC scores decreased as a result of the increase of platelets and fibrinogen and improvement of FDP. Thrombin-antithrombin III complex, D-dimer and plasmin-α<sub>2</sub> plasmin inhibitor complex showed an even higher value at the endpoint of FUT administration. These results indicate that patients with DIC after cardiopulmonary bypass may have severe fibrinolytic acceleration and that administration of FUT can be useful in those cases.
