ABSTRACT
A 68-year-old man suffered a pain in his right groin and was diagnosed with deep vein thrombosis at a previous medical clinic, two months earlier. He was referred to our hospital to treat deep vein thrombosis. However, adventitial cystic disease of the femoral vein was suspected from findings of preoperative contrast CT and ultrasonography. Under general anesthesia, the operation was performed. The venous wall was resected including an adventitial cyst, which was followed by the venous reconstruction using an autologous vein patch. Anticoagulant therapy was continued after the operation for one year. He was followed for 18 months after the surgery without a recurrence of the adventitial cystic disease. Venous adventitial cystic disease is extremely rare and may be misdiagnosed as deep vein thrombosis. Careful follow-up is mandatory, because the postoperative recurrence rate is reported to be substantially high.
ABSTRACT
A 39-year-old man was found to have left iliac artery rupture, and was transferred to our department. Emergency surgical repair was done, however, his intra- and postoperative condition precluded primary abdominal closure. On the 8th postoperative day, temporary abdominal closure (TAC) was performed using Composix Mesh TM and negative pressure wound therapy (NPWT). On the 19th day after the first surgery, an emergency reoperation was needed because of the rupture of the common hepatic artery aneurysm, of which there was no finding on admission. After the reoperation of the hepatic artery aneurysm, TAC was again performed using new Composix Mesh. On the 43rd day after the first surgery, the abdominal wall reconstruction without Composix Mesh was done using components separation and the anterior rectus abdominis sheath turnover flap method. On the 106th day after the first surgery, he had recovered well and was discharged. The genetic testing revealed COL3A1 mutation, which is specific for vascular type Ehlers-Danlos syndrome. When long-term open abdominal management is necessary after the abdominal aortic surgery, TAC with Composix Mesh and NPWT may be a useful alternative. Artery rupture in young people is a finding that should be considered suspicious for vascular type Ehlers-Danlos syndrome, which is difficult to treat.
ABSTRACT
A 77-year-old woman with previous aortic grafting for abdominal aortic and iliac artery aneurysms developed a blue toe in her left foot. Enhanced CT showed a high density area around the vascular graft of the left iliac artery, which partially protruded into the graft. Because of the elevated <i>β</i>-D glucan level, fungal infection of the vascular graft was strongly suspected. Her general condition precluded the graft removal. Instead, thrombectomy was performed. Microbial examination of the removed clot revealed infection by <i>Aspergillus fumigatus</i>. Voriconazole was administered for 3 months. The <i>β</i>-D glucan level was normalized. Only thrombectomy and Voriconazole administration can be an alternative in case with vascular graft infection by <i>Aspergillus</i>.
ABSTRACT
A 65-year-old woman with a history of chronic atrial fibrillation was admitted for treatment of progressively worsening pain in the right forearm, which had begun several days before presentation. She did not have a palpable right brachial pulse, but her axillary pulse was palpable. We suspected acute thromboembolism of the brachial artery, and tried emergency thrombectomy via the brachial artery. However, her brachial artery was completely occluded with white organized thrombi, which was the cause of the chronic occlusion. Vasodilative drugs were administered, but her symptoms remained. Preoperative angiography showed the right brachial artery to be occluded and the ulnar artery could be partially visualized via the collateral arteries. We performed bypass grafting between the right axillary and ulnar artery, using an autologous saphenous vein graft. Her symptoms improved, and postoperative angiography revealed the bypass graft to be patent. The possibility of acutely worsening chronic ischemia should be considered, even if symptoms indicate acute thromboembolism of the extremities.
ABSTRACT
A 77-year-old man, who had undergone total cystectomy, was transferred to our hospital because of repeated arterial bleeding from the left cutaneous urostomy on urostomy catheter exchange. Abdominal CT scan revealed infrarenal aortic and bilateral common iliac aneurysms. Multidrug-resistant <i>Pseudomonas</i> was detected from preoperative urine culture. A fistula between the left iliac artery and the left ureter was strongly suspected and an operation was performed. Aneurysmectomy and graft replacement with a bifurcated graft was conducted. Both limbs of the Y-graft were anastomosed to the right internal and external iliac artery. The left lower extremity was revascularized using femorofemoral bypass. After left nephrostomy, the graft was wrapped around with an omental flap. The postoperative course was uneventful, without infective complications.
ABSTRACT
Higher incidence of spinal cord injury has been reported in total aortic arch replacement using a stented elephant trunk compared with the conventional one, perhaps due to embolism of atheromatous plaque to the spinal cord arteries. We report a case with delayed-onset lower spinal cord injury after replacement of the aortic arch and the descending thoracic aorta using a stented elephant trunk. A 69-year-old man who had a history of abdominal aortic aneurysm repair using a Y-graft and untreated Crawford's type II thoracoabdominal aortic aneurysm underwent replacement of the aortic arch and the descending thoracic aorta using a stented elephant trunk. He developed weakness of the lower extremities 4 days after the operation. Since a preoperative computed tomography demonstrated thrombus and atheroma in the aneurysm, atheromatous plaque that can cause embolization of the spinal cord arteries was suspected to be responsible for spinal cord injury. As this technique is mostly applied to patients with severe atheromatous aortic disease, embolization of the intercostal arteries or other main branches caused by manipulation of a stent graft must be avoided.
ABSTRACT
A 55-year-old man was admitted to our hospital with angina pectoris. Coronary angiography revealed that the left anterior descending artery (LAD) originated from the proximal right coronary artery (RCA) which arose from the right coronary sinus of Valsalva, while the circumflex artery (CX) arose from the left coronary sinus of Valsalva. Multiple coronary lesions included total obstruction at the proximal RCA after branching the LAD, 75% stenosis at the origin of the LAD, and 90% stenosis at the proximal CX. These lesions were revascularized with the left interthoracic artery to the LAD, the radial artery to the RCA, and a couple of saphenous vein grafts to the CX. Postoperative angiography confirmed patency of all grafts. Anomalous coronary artery is found to be 0.62-0.83% by angiography. A rare anomalous coronary artery is documented in this article, which has been reported to be 4.4% of all anomalous coronary arteries.
ABSTRACT
A 74-year-old woman was admitted to our hospital with a diagnosis of a pseudoaneurysm 5 months after graft replacement of the ascending aorta, and underwent re-replacement employing left ventricle venting through a left anterior thoracotomy. Culture of the thrombi in the pseudoaneurysm revealed Psuedomonas infection. On the 11th postoerative day, a single-stage procedure of irrigation, debridment, and immediate closure with omental transposition was performed. Although the chest CT scan 1 month after the omental transposition revealed a residual abcess, it was completely obliterated after 2 months without further operation.
