Clostridium septicum aortitis with associated sigmoid colon adenocarcinoma

We report an unusual case of Clostridium septicum aortitis with associated adenocarcinoma of the sigmoid colon. An 87-year-old man with multiple medical comorbidities presented with a 1-week history of severe abdominal pain in the left lower quadrant of his abdomen. Abdominal computed tomography showed, in addition to a mass in the sigmoid colon, a gas density within the wall of the abdominal aorta with extensive periaortic fat stranding and some additional gas densities in the proximal left common iliac artery. The patient refused surgery, and was treated with intravenous antibiotics. He died 5 weeks later. The development of Clostridiumsepticum aortitis, an extremely rare but life-threatening infection, is highly associated with an underlying colonic malignancy and demands immediate surgical intervention.     

Cryptococcal aortitis presenting as a ruptured mycotic abdominal aortic aneurysm.

Mycotic processes occasionally complicate atherosclerotic aortic disease and usually require aggressive surgical therapy to control sepsis and prevent arterial rupture. Rarely, fungal organisms are responsible for primary infection of the abdominal aorta. We report the first case of Cryptococcal aortitis presenting as a ruptured abdominal aortic aneurysm. The surgical, pathologic, and microbiologic aspects of fungal aortitis are discussed.     

Mycotic aneurysm of the infrarenal abdominal aorta infected by Clostridium septicum: a case report of surgical management and review of the literature

We report a surgical case of mycotic aneurysm of the infrarenal abdominal aorta infected by Clostridium septicum. The patient was first treated with an in situ prosthetic graft replacement. When the infection recurred 5 weeks after the aortic surgery, the patient was successfully treated by transposition of rectus abdominis muscle flap around the graft. Only 19 cases of mycotic aneurysm or aortic dissection caused by Clostridium septicum have been reported. Ten of 12 patients who underwent vascular surgery survived, whereas all 7 patients who did not undergo surgery died. Surgical treatment should be undertaken since the surgical results seem satisfactory.     

<Emphasis Type="Italic">Clostridium septicum</Emphasis> myonecrosis complicating diarrhea-associated hemolytic uremic syndrome

We report the case of a 19-month-old male child with diarrhea-associated hemolytic uremic syndrome (HUS) who developed swelling of the right arm at the site of a peripherally inserted central venous catheter (PICC), fever, and later, ecchymosis. Wound cultures at the time of surgical debridement grew Clostridium septicum. The child subsequently required amputation of the right arm and prolonged therapy with parenteral penicillin and clindamycin. Clostridium septicum infections in children with HUS have been associated with a high rate of mortality. Along with colon cancer, diarrhea-associated HUS comprises a clinical entity which appears to predispose to atraumatic C. septicum infection, where acidic and anaerobic conditions in the diseased colon favor C. septicum invasion. Though not well recognized among pediatric nephrologists, C. septicum infection constitutes a severe, albeit rare, complication of diarrhea-associated HUS, but one in which a high index of suspicion is warranted as aggressive surgical and antibiotic therapy may be life-saving.     

Gas gangrene with ulcerative colitis under immunosuppressive therapy: report of a case

We report on a 30-year-old male with ulcerative colitis who developed a spontaneous gas gangrene in the right limb, the gluteal muscles and the retroperitoneal region under immunosuppressive therapy. In spite of immediate aggressive surgical and antibiotic therapy the massive infection led to septicemia and ultimately death. Clostridium septicum was identified with multiple local manifestations in the skeletal muscles. Gas gangrene is extremely rare in patients with ulcerative colitis or Crohn's disease and immunosuppression. The therapeutic options are discussed and the relevant present literature is reviewed.     

Sliding free transverse rectus abdominis myocutaneous flap for closure of a massive abdominal wall defect: A case report

Despite considerable advances in reconstructive surgery, massive abdominal wall defects continue to pose a significant surgical challenge. We report the case of a 72‐year‐old morbidly obese female patient with Clostridium septicum‐related gas gangrene of the abdominal wall. After multidisciplinary treatment and multiple extensive debridements, a massive full‐thickness defect (40 cm × 35 cm) of the right abdominal wall was present. The abdominal contents were covered with a resorbable mesh to prevent evisceration. Finally, the composite defect was successfully reconstructed through a contralateral extended free transverse rectus abdominis myocutaneus (TRAM) flap (50 cm × 38 cm). An arterio‐venous loop to the superficial femoral vessels using the great saphenous vein was necessary to allow the flap to reach the defect. Postoperatively, a minor wound healing disorder of the flap was successfully treated with split skin grafting. Six month after surgery, the patient presented with a completely healed flap coverage area and a small abdominal hernia without the need of further surgical revision. This case illustrates the use of a sliding free TRAM flap for closure of a massive abdominal wall defect.     

Clostridium myonecrosis: a complication of inguinal hernia repair

Clostridial myonecrosis is a necrotizing soft tissue infection characterized by muscular necrosis and, by extension, that of the surrounding tissue. If this infection develops quickly, it can cause septic shock and death if treatment is delayed. This infection does not occur frequently in civil medicine but nor is it exceptional after traumatic injuries or as a septic infection resulting from certain surgical interventions. Spontaneous development of clostridial myonecrosis is not uncommon (most commonly produced by the Clostridium septicum genus), propagated mainly from the colon in patients with neoplasia and in poor health. Consequently, in patients of bacteremia caused by C. septicum, colonic tumor must be ruled out. We present a new case of C. septicum myonecrosis of the abdominal after elective inguinal hernia repair.     

„Spontaner“ Gasbrand mit Kompartmentsyndrom bei einem diabetischen Patienten

Atraumatic infections due to Clostridium septicum are known to be associated with immunosuppression or even malignancy. In this case report, we present a patient with severe Clostridium septicum infection related to advanced colon cancer that had not previously been diagnosed. The case demonstrates the strong association between Clostridium septicum infections and malignancy, particularly in the presence of other predisposing diseases such as diabetes mellitus. It strongly suggests excluding malignant neoplasms, especially of the gastrointestinal tract, when severe Clostridium septicum infections occur. Moreover, if patients with known colorectal or other malignancy develop septicaemia or spontaneous gas gangrene, clinicians should be aware of Clostridium septicum as one of the main causative agents, as early diagnosis and aggressive treatment are important to improve prognosis.     

Suprarenal Clostridium septicum Aortitis with Rupture and Simultaneous Colon Cancer

We report a case of combined colon cancer and Clostridium septicum aortitis involving the suprarenal abdominal aorta with rupture. An 82-year-old male presented with fever, abdominal pain, and back pain associated with constipation. He was successfully treated by in situ aortic graft placement with polytetrafluroethylene and concomitant colon resection. Only 20 other cases of C. septicum mycotic aneurysm, aortitis, or aortic dissection have been reported. Concomitant surgical treatment for Clostridium aortitis or mycotic abdominal aortic aneurysm and colon cancer can be accomplished successfully in selected cases when the diagnosis of both conditions is made preoperatively.     

Aortic root replacement by cryopreserved homogrft for prosthetic valve detachment case due to aortitis

We present a surgical case of a 35-year-old man with aortitis. He had been performed the reconstruction of the right common carotid artery with a saphenous vein graft at 23 years old for his ruptured aneurysm by aortitis. The aortic valve replacement and CABG (LITA to LAD, SVG to D1 and SVG to RCA) were performed for aortic regurgitation and aneurysms of coronary arteries two years ago. The diastolic murmur was first heard at 18 months after the operation. The echocardiography on admission showed an abnormal movement of the prosthetic valve with perivalvular leakage. At the second operation, the valve dehiscence was observed. Although the tissues around the dehiscence was friable and edematous, there wre no signs of vegetation nor abscess formation. His aortic root was replaced with a cryopreserved aortic allograft conduit. His postoperative course was uneventful and aortography revealed neither aortic regurgitation nor stenosis of the coronary artery or SVGs. We think the softness of the allograft valve ring is favorable in valve detachment cases due to not only infection but also aortitis, to prevent redetachment.     

Abdominal aortic aneurysm repair complicated by infection with Clostridium septicum

Aortic stent-graft infection after endovascular abdominal aortic aneurysm (AAA) repair is an uncommon, but very serious complication with potentially devastating consequences.(1) Traditional open techniques of repair of AAA demonstrate an infection rate of 0.5-3%. The exact rate of infection with endovascular repair is unknown, but literature review demonstrates an overall incidence of 0.43-1.17% retrospectively.(2,3) Etiology of endovascular graft infections typically results from flora derived from the skin or gastrointestinal tract.(4)Clostridium septicum is a naturally occurring anaerobic bacterium native to the gastrointestinal tract. It is typically associated with spontaneous nontraumatic gas gangrene owing to bacteremia from the gastrointestinal tract with an incidence rate of 0.07%.(5) To our knowledge, this is the first reported case of endovascular AAA graft infection owing to Clostridium septicum species.     

Spontaneous gas gangrene associated with occult carcinoma of the colon: a case report and review of literature

Clostridium septicum infection is a rare cause of spontaneous nontraumatic gas gangrene. The resultant myonecrosis is acutely painful and rapidly fatal. The infection occurs in the absence of trauma and is usually associated with an underlying malignancy. A case of spontaneous gas gangrene of the upper limb caused by C. septicum infection associated by carcinoma of the colon is presented, with a review of the literature.     

Endovascular repair of late abdominal aortic aneurysm rupture owing to mixed-type endoleak following endovascular abdominal aortic aneurysm repair

We report the successful endovascular repair of a ruptured abdominal aortic aneurysm (AAA) in a multimorbid patient 8 months after endovascular abdominal aortic aneurysm repair (EVAR). A 74-year-old man with a history of EVAR 8 months earlier presented with hypotension, severe back pain, and tenderness on abdominal palpation. A contrast-enhanced computed tomographic scan showed a large retroperitoneal hematoma and confirmed the diagnosis of secondary abdominal aortic rupture. Because the patient had severe comorbidities, the endovascular method was chosen for further management. Two stent grafts were placed appropriately to eliminate a type 1a and a type 3 endoleak owing to modular separation of the left iliac graft limb from the main body stent graft. An additional self-expanding stent was deployed in the solitary right renal artery to open its origin, which was partially overlapped by the proximal cuff. The patient was discharged on the tenth postoperative day and is alive and well 1 year postoperatively. This case indicates that endovascular repair is feasible not only in cases of primarily ruptured AAAs but also in secondarily ruptured AAAs after failure of EVAR.     

Replacement of the abdominal aorta with a sutureless intraluminal ringed prosthesis

To evaluate our experience with sutureless intraluminal ringed grafts in the abdominal aorta, we reviewed all patients who were managed with this device from 1980 to 1987. Thirty-one patients were identified with a mean follow-up time of 41 months. Three patients had suprarenal aneurysms and four had ruptured abdominal aneurysms. Average tube graft insertion time was 17 minutes and required 0.9 units of transfused blood. There were two postoperative deaths (6 percent), both secondary to myocardial infarction. None of the patients with ruptured or suprarenal aneurysms died. No patients had permanent renal or neurologic deficits, and no instances of postoperative bleeding, wound infection, pseudoaneurysm formation, or graft migration were encountered. The sutureless intraluminal graft can be implanted easily and quickly and is safe for use in the abdominal aorta. It is particularly helpful in the management of suprarenal or ruptured abdominal aneurysms, in which speed is important, and in effecting technically difficult anastomoses to friable aortic tissue.     

Repair of right sided Traumatic Diaphragmatic Hernia with intrathoracic herniation of liver and a segment of ruptured jejunum—a case report and review of literature

We present this rare case of a 24 year old male who was knocked down by a slowly backing truck when the rear wheels climbed on to the right side of the abdomen and on hearing the shouts of people rolled forwards causing a partial run over injury. He was resuscitated and treated conservatively. An X Ray Chest done 24 h later showed right sided chest wall fracture, right basilar opacity suggesting chest injury with localized haemothorax/pulmonary contusion and a chest tube was inserted through Rt. 5th intercostal space. Initially some blood came out. But on the third day bile was seen coming out of the intercostal drain prompting a diagnosis of traumatic rupture of diaphragm with liver injury. A Magnetic Resonance Imaging (MRI) scan was done when the diagnosis of ruptured right dome of diaphragm with Traumatic Diaphragmatic Hernia (TDH) with herniation of liver into the right hemithorax was made. Surgical exploration on the 4th day through right thoraco- abdominal approach confirmed TDH with herniated liver into the right hemithorax without any injury to the liver, hepatic blood vessels or the bile ducts but an unsuspected rupture in a herniated loop of jejunum wedged into the right hemithorax anterior to the liver with biliary discharge into the right hemithorax but without any peritoneal soiling. Repair was done by resection anastomosis of the ruptured jejunum, reduction of the liver into the abdomen, suturing of the torn diaphragm effectively obliterating the hernia orifice and reinforcing it with a polypropylene mesh anchored to the chest wall. There was a stormy post operative phase involving burst thorax which was corrected by re-exploration of the thoracic portion of the thoraco abdominal wound, wound toileting and resutured. The wound healed after 2 months. The patient is doing well after 20 months of follow up.     

Successful surgical treatment for implanted intraperitoneal metastases of ruptured small hepatocellular carcinoma: Report of a case

We report herein the case of a 53-year-old man with disseminated intraperitoneal metastases caused by the rupture of small hepatocellular carcinoma (HCC). He was admitted to our hospital in shock after suffering a trauma injury to the upper abdomen. Ultrasonography revealed a massive hemoperitoneum. At surgery, 4000 ml of blood was drained from the abdominal cavity and a ruptured tumor, 2 cm in diameter, was found in the right lobe of the liver. The tumor was resected with an adequate surgical margin and subsequent microscopic examination confirmed a diagnosis of moderately differentiated HCC without associated liver cirrhosis. The patient was readmitted 14 months later, following the development of right lower quadrant pain. Ultrasonography and computed tomography revealed extrahepatic abdominal tumors, and abdominal angiography demonstrated four intraperitoneal tumors. At surgery, four implanted metastases adhered to the greater omentum were found and resected. No other tumors were detected. Microscopically, all four tumors were confirmed as moderately differentiated hepatocellular carcinoma. Ruptured HCC may lead to implanted intraperitoneal metastasis, but rupture of small HCC is very rare. While hepatic resection is the treatment of choice for ruptured HCC, according to our review of the literature, only a few patients have survied long-term after resection of implanted metastasis.     

Necrotizing bacterial skin and software tissue infection with muscular involvement revealing of cancer of the colon

We report the case of a 38-year-old woman with a necrotizing bacterial skin and soft tissue infection with muscular involvement. The clinical picture was similar to a gaseous gangrene of the right lower limb with a septic shock and multiple organ failure, without predisposing factor such as trauma, and necessitating a hip amputation. The primary site of the disease was a perforated colic adenocarcinoma with peritoneal and retroperitoneal infection. The association of necrotizing skin and soft tissue infection with muscular involvement due to Clostridium septicum to a neoplasma is classical and in front of such an infection a neoplasma should be researched.     

Midaortic syndrome and subarachnoid hemorrhage associated with ruptured middle cerebral artery aneurysm: case report and review of the literature

OBJECTIVE AND IMPORTANCE: We describe the presentation, screening, management, and clinical outcome of a 21-year-old man who sought care for a ruptured middle cerebral artery (MCA) aneurysm and midaortic syndrome (MAS). Only three cases of MAS and intracranial aneurysm rupture have previously been described in the literature. CLINICAL PRESENTATION: Cranial computed tomographic (CT) scanning, cerebral and abdominal angiography, and multislice three-dimensional CT angiography were used to evaluate intracerebral hemorrhage and to assess medically intractable hypertension in the patient. Digital subtraction angiography revealed a right MCA aneurysm, and multislice three-dimensional CT angiography revealed narrowing of the abdominal aorta. INTERVENTION: The patient's right MCA aneurysm was successfully clipped via a right pterional craniotomy. A narrowed abdominal aorta was confirmed by an abdominal aortic angiogram (performed at Day 5 after surgery) and then dilated by using percutaneous transcatheter angioplasty during the same session. The patient was normotensive even without antihypertensive medications. Neurological examination and postoperative cranial CT findings were within normal limits at the last follow-up examination, performed 4 months after the operation. CONCLUSION: Our patient is the first reported case of ruptured MCA aneurysm with MAS in an adult. The most important problem in the management of MAS associated with ruptured intracranial aneurysm is medically intractable hypertension, which may markedly increase the incidence of rebleeding. It is hard to achieve normotension unless the narrowed aorta and its branches are dilated. For these reasons, MAS should be considered in patients with medically intractable hypertension associated with ruptured intracranial aneurysm.     

Ruptured syphilitic ascending aortic aneurysm; report of a case

Syphilitic cardiovascular disease has become a rarity today. It most commonly affects the ascending aorta and aortic arch. A case is reported of a 50-year-old female with a ruptured syphilitic ascending aortic aneurysm who underwent an emergency operation. The patient was emergently admitted with complaint of severe dyspnea, circulatory shock due to cardiac tamponade was observed in the emergency room. Bentall's procedure was performed. Intraoperative findings showed multi-cystic dilatation of an aortic root. Penetration was existed on right side posterior wall of an aortic root. Postoperative pathological examination of the aneurysmal wall revealed the characteristic finding of syphilitic aortitis. The postoperative course was uneventful and the patient has been doing well at period of 3 years after operation.     

Fatal multifocal metastasis of Clostridium septicum: a case report.

Clostridium septicum infection produces rapidly spreading tissue necrosis, often, but not exclusively, associated with trauma or large bowel malignancy. We present a unique case of atraumatic infection leading to multifocal metastatic spread in a neutropenic patient, emphasising the devastating potential of this disease.
