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.

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.

A 65-year-old man was admitted with subacute myocardial infarction. During medical treatment, the patient lost consciousness as a result of an atrioventricular block and underwent an operation for an emergency percutaneous coronary intervention in the right coronary artery. In a follow-up examination, transthoracic echocardiography and computed tomography showed a left ventricular pseudo-false aneurysm, and therefore another operation was carried out. The operative findings showed that the heart markedly adhered to the pericardium and the aneurysm at the apex. The patient then underwent a double-patch closure of the ruptured point using an equine pericardial patch and a Dacron patch. No perioperative complication was observed. Left ventricular pseudo-false aneurysm is a rare complication following myocardial infarction. Here, we report a successful case of a double-patch closure of a pseudo-false aneurysm.

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.

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.

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.

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.

A 42 year-old woman with Marfan syndrome, who had replacement of the ascending aorta for acute aortic dissection several years ago, was found to have distal aortic arch aneurysm. The aneurysm had small entries at cervical arterial branches and large re-entry at the left external iliac artery. It was necessary to perform two-staged operation Bentall procedure with total arch replacement and abdominal aortic replacement with re-entry closure. It was usually performed with a primary entry closure for chronic aortic dissection, but massive invasion was expected. We performed catheter angiography for entry and re-entry, and decided to perform preceding re-entry closure. First, we underwent replacement of the abdominal aorta, and then successfully performed the Bentall procedure with total aortic arch replacement. The catheter angiography was useful for decision-making for medical treatment.

A crossover study was conducted to evaluate suppressive effect of a commercially available green juice (Katuna-Aojiru;Egao Co., Ltd.) containing mulberry leaf powder as the main ingredient on postprandial hyperglycemia. The blood glucose and iAUC (0-120min) values after loading cooked white rice were significantly lower with the consumption of Katuna-Aojiru than with the consumption of water. Katuna-Aojiru is effective in controlling postprandial blood glucose.

Retrograde type A aortic dissection (RTAD) following thoracic endovascular aortic repair (TEVAR) is a lethal complication. A 54-year-old woman with bovine aortic arch presented with dilatation of the descending aorta due to chronic type B aortic dissection. She underwent TEVAR in zone 2 for closure of the entry site just below the origin of the left subclavian artery. On the day after TEAVR, she showed right hemiparesis, and was diagnosed with cerebral infarction on MRI and RTAD on CT. She underwent an emergent operation. The entry was at the proximal end of the bovine trunk, where the edge of the bare stent stuck out. We performed partial arch replacement with entry resection. Her postoperative course was uneventful. She was transferred to another hospital for rehabilitation 37 days after the surgery.
