Popliteal pseudoaneurysm and arteriovenous fistula after acupuncture.

Most popliteal arteriovenous fistula and pseudoaneurysm formation are related to trauma. Few cases have previously been reported after acupuncture therapy. Such events are typically observed when the procedure is performed by non-medical acupuncturist. They may present with acute ischemia, recent claudication, distal emboli, or less commonly rupture. Duplex ultrasound should be considered as the 1st method of investigation. Computed tomography scanning is particularly accurate in making the diagnosis. Treatment strategies consist of surgery or endovascular management. The most commonly performed surgical technique for popliteal pseudoaneurysm repair is resection with bypass grafting, whereas popliteal arteriovenous fistula are usually treated surgically with ligation and primary repair. Endovascular procedure using a stent-graft is thought to be a reasonable option for treating popliteal false aneurysm or even arteriovenous fistula. We will describe two cases of an arteriovenous fistula and pseudoaneurysm of the popliteal artery that developed after acupuncture needling in the region of the popliteal artery.

[Middle aortic coarctation: a rare vascular disorder]. / La coarctation de l'aorte thoracique descendante: mid-aortic syndrome. À propos de trois cas.

OBJECTIVE: Coarctation of the descending thoracic aorta is uncommon, with controversial etiology. Usually, severe hypertension is the main symptom; lower extremity claudication is less often found. Surgical management remains the standard for long coarctation and provides good results. METHODS: We report three cases of coarctation of the descending aorta operated at our department of cardiovascular surgery of Hospital La Rabta between January 2012 and December 2013. RESULTS: The median age was 19 years and the median follow-up was 16 months. Hypertension was the most common clinical manifestation. The diagnosis was made by computed tomography angiography. Two cases were treated by an aorto-aortic bypass and one by subclavian-descending aorta bypass. Recovery was excellent, with a decrease in antihypertensive medications (four to two) and restoration of all distal pulses. CONCLUSIONS: Middle aortic coarctation is a rare entity. Etiologies include congenital, acquired, inflammatory and infectious causes. The condition is considered a life-threatening emergency as a result of the complications associated with severe hypertension. Depending on technical considerations, open surgical bypass remains the standard repair for mid-aortic syndrome.

[Aortic stent migration: a rare complication after endovascular repair]. / Migration d'endoprothèse aortique : une complication rare après traitement endovasculaire.

Migration of an aortic stent is one of the most serious complications that can occur during follow-up after endovascular repair of an abdominal aortic aneurysm. We report the case of a 75-year-old man who underwent endovascular treatment for an infra-renal aortic aneurysm using an aorto-mono-iliac stent associated to a femoro-femoral bypass. The angiography performed at the end of procedure showed complete exclusion of the aneurysm. The postoperative course was uneventful. CT scans at 1, 6 and 12 months were normal. The CT scan at the 18th month showed a proximal migration of the stent, which was complicated by a type 1 endoleak and a stent disjunction with a type 3 endoleak. Revision surgery was indicated but the patient died from aneurismal rupture pending treatment. The migration of an aortic stent is a rare but serious complication of endovascular aneurysmal repair. Prevention requires a precise anatomical selection and adequate deployment of the stent graft.

[Traumatic dissection of the innominate artery. A case report]. / Dissection traumatique du tronc artériel brachiocéphalique. À propos d'un cas.

INTRODUCTION: Lesions affecting the supra-aortic arterial trunks often occur in a contest of severe chest trauma. They are rarely isolated and can be life-threatening. We report a case of surgery for an isolated traumatic dissection of the innominate artery. CASE REPORT: A 48-year-old patient had a road accident causing head injury, trauma of the left lower limb and blunt chest trauma. At the physical exam, the pulse at the upper right limb was weak compared to the contralateral member. A pressure gradient of 50mm Hg was recorded between the two upper limbs. A whole body scan revealed a dissection of the innominate artery sparing its origin and bifurcation. Cervicotomy and sternotomy was necessary to achieve control. After heparinization and clamping, a prosthetic bypass was inserted to replace the innominate artery. The postoperative course was uneventful and the pressure gradient between the two upper limbs disappeared. CONCLUSION: Lesions of the brachiocephalic arterial trunk are not frequent but they are serious. A careful physical exam at admission helps detect them. Prognosis is directly linked to early diagnosis and management. Conventional surgery provides good results and remains the standard treatment for these lesions.

[Acute rupture of an abdominal aortic aneurysm revealing Takayasu arteritis]. / Anévrysme de l'aorte abdominale sous-rénale rompu inaugural d'une maladie de Takayasu chez un homme de 39ans.

Arterial aneurysms are most commonly (60% of cases) located in the infrarenal abdominal aorta. An inflammatory mechanism is involved in only 10% of cases. Infrarenal abdominal aortic aneurysms revealing Takayasu's disease is unusual. Takayasu's disease is a rare vasculitis affecting large arteries in young people. It is 10 times more common in women. We report the case of an acute rupture of an abdominal aortic aneurysm revealing Takayasu arteritis in a 39-year-old man with an uneventful medical history.

[Management of traumatic aortic rupture. About 37 cases]. / Prise en charge des ruptures de l'isthme aortique post-traumatiques. À propos de 37 cas.

OBJECTIVES: The aim of this study was to review our experience in the management of traumatic rupture of the aortic isthmus, to evaluate the results of surgery and endovascular exclusion and to develop an adequate therapeutic strategy based on the existence and severity of associated injuries. MATERIAL: A series of 37 patients presenting posttraumatic aortic rupture associated with other severe lesions was collected from 2000 to 2012. There were 33 males and four females, mean age 38 years. In this series, 25 patients underwent surgical treatment and 12 endovascular exclusion. RESULTS: Six patients died during or after surgery. Overall mortality was 16% (24% in the surgery group). The postoperative period was uneventful in all patients treated with the endovascular procedure. Postoperative computed tomography controls at one week, 1 month and 12 months showed good positioning of the stent without endoleakage. CONCLUSION: Traumatic aortic rupture is often the result of a severe high-energy chest trauma. Other serious injuries are often associated. Results of immediate surgical repair are associated with high morbidity and mortality. The advent of endovascular treatment has revolutionized the treatment of traumatic aortic rupture, especially in patients with a high surgical risk.

[Surgical management of extracranial carotid artery aneurysm]. / Traitement chirurgical des anévrismes carotidiens extracrâniens : à propos de dix cas.

OBJECTIVE: Aneurysm of the extracranial carotid artery is rare. The embolic risk mandates prompt intervention once diagnosed. The aim of this study was to determine therapeutic techniques, their indications and outcomes. PATIENTS AND METHODS: We report a series of ten patients who underwent surgery for extracranial carotid artery aneurysm in the cardiovascular surgery department of La Rabta hospital. RESULTS: There were six men and four women, mean age 43 years. All patients were symptomatic (swelling and pulsatile cervical mass). Two patients had dysphonia and one patient underwent an emergency procedure because of aneurismal rupture. Aneurismal excision was performed in most patients. The arterial reconstruction was performed by end-to-end anastomosis in four cases, interposition of an autologous venous graft in four, interposition of a prosthetic graft in one and suture of a small rent in the artery in one. There was no postoperative mortality. Early postoperative morbidity included one recurrent laryngeal nerve injury, one hypoglossal nerve injury, one stroke and one infection with thrombosis of a prosthetic graft. The follow-up was uneventful. CONCLUSION: Surgical treatment of extracranial carotid aneurysms is required, in most cases with good results. Endovascular treatment may be an effective therapy in selected cases.

[Macular tuberculoma and optic neuritis: rare association with tuberculosis meningoencephalitis]. / Tuberculome maculaire et névrite optique : association rare au cours d'une méningo-encéphalite tuberculeuse.

INTRODUCTION: Tuberculosis is an endemic disease responsible for death and morbidity in developing countries. OBSERVATION: A 50-year-old man with no medical history was admitted to the emergency department for meningism associated with fever and confusion. The ophthalmic exam showed a decline in left visual acuity, reduced to light perception, VIth nerve left oculomotor paralysis, ocular fundus demonstrating a yellow tumor located on the posterior segment, measuring 1.5-2mm, papillomatous and prominent in the vitreous cavity. Fluorescein angiography showed a peritumoral choroiditis area, miliary tubercles of the choroid, and sectorial papillomatous edema. Color retinography unmasked inflamed posterior vitreous areas. Echography demonstrated a 4- to 5-mm oval hyperechogeneous and calcified tumor along with hyperechogeneous vitreous areas. Lumbar puncture showed lymphocytic meningitis associated with hyponatremia. The CT scan and MRI demonstrated optic neuritis. The antibiotic therapy was initiated and the outcome was favorable. CONCLUSION: This case report shows the importance of systematic ocular fundus in the presence of systemic tuberculosis and outlines the assessment of color retinography to unmask vitreous lesions. It shows the importance of radiological imaging in the semiological study of orbital and cerebral lesions.

[False aneurysm of left ventricle after nonpenetrating chest trauma (about one case)]. / Faux anévrisme du ventricule gauche après un traumatisme fermé du thorax (à propos d'un cas).

Ischemic heart disease is the most common etiology of aneurysms of the left ventricle. The latter can also result from trauma. We report a case of a patient operated for false aneurysm of the left ventricle revealed by dyspnea and occurring six years after a nonpenetrating chest trauma. Follow-up after surgery was good with no complication occurring. In conclusion, this lesion must be considered in case of chest trauma and can be easily detected by echocardiography or CT scan.

[Anastomotic false aneurysms after under-diaphragmatic bypasses: about 25 cases]. / Les faux anévrismes anastomotiques sur pontages sous-diaphragmatiques: a propos de 25 cas.

The purpose of our study is to determine the causes and the management of anastomotic aneurysms. We report the cases of 25 patients with a mean age of 64 years at the time of initial surgical revascularisation. The mean interval between the first operation and the occurrence of anastomotic aneurysm is 5 years (range 2 months-11 years). The treatment consists on the interposition of a graft in 8 patients, anastomotic angioplasty in 9 patients and the reconstruction of the anastomosis in 8 patients. Hospital mortality was 20%. Late death occurs 3 patients and the long-term morbidity was evaluated at 22%. A recurrence of anastomotic false aneurysm occurred in 4 patients (16%) (Range 7 months-1 year). In conclusion anastomotic false aneurysm is one of the major complications of vascular reconstruction; careful follow-up can detect the rare instances of anastomotic aneurysm and reoperation can be accomplished with a low-rate of adverse outcome.

[Cardiac myxoma. Surgical treatment. About 20 cases]. / Les myxomes cardiaques. Prise en charge chirurgicale. A propos de 20 cas.

INTRODUCTION: Cardiac myxoma is the commune cardiac tumors. Their clinical status depends in the anatomic type. The aim of this study is to evaluate our results and to compare them for literature. PATIENTS AND METHODS: From January 1990 to June 2004, 20 patients (8 males and 12 females) with mean age of 49 years underwent surgical treatment of cardiac myxoma. The tumors were in left atrium in 14 cases, in right atrium in 4 cases and biatrial in 2 cases. Surgical treatment consisted in complete resection of the tumor in all cases associated with partial atrial septal resection in 9 cases. RESULTS: There is not death in the postoperative outcome. The mean follow up is 50 months. The late mortality rate was 10%. All patients are asymptomatic and the echocardiography control showed no tumor recurrence. CONCLUSION: Cardiac myxoma is the communist primary tumor of the heart. Diagnosis is based upon echocardiography. Surgical management has well out come with low morbidity and mortality. Late results are satisfactory but regular screening is recommended although risk of recurrence is low.

[Beating heart coronary revascularisation. Report of 26 cases]. / La revascularisation myocardique chirurgicale a coeur battant. A propos de 26 cas.

The beating heart coronary artery bypass technique is becoming more popular in many cardiac units throughout the world. This relativity new technique has prompted surgeons and anaesthetists to review and analysed the routine approach to coronary surgery. In this study we reviewed 26 patients operated off pump technique group I (50 %) and the group II (50 %) operated on pump coronary artery bypass. The patients in the group II were more symptomatic with more heart function, than group I. The postoperative cause of the two groups was similar. This retrospective analysis shows that beating heart technique for coronary surgery can be offered to many patients with good out come and on pump technique can be more safety specially in case of poor myocardial function.

[Cross over bypasses ilio-femoral and femoro-femoral. Indications and results about 60 cases]. / Les pontages croisés fémoro-fémoraux et ilio-fémoraux. Indications et résultats. A propos de 60 cas.

UNLABELLED: The goal of this retrospective study is to review indications and results of cross over bypasses. METHODS AND MATERIAL: between January 1990 and December 2000, 60 patients (all males with mean age = 60 years) underwent cross over bypass for unilateral iliac occlusive disease: femoro-femoral in 48%, ilio-femoral in 44% and ilio-popliteal in 8%. RESULTS: mortality was 5% while complications occurred in 13.3%. Early limb salvage rate was 92%. During follow-up (mean: 32 months) we noticed 13 late thrombosis. The actuarial patency rate being at 83.5%, 74% and 67% at 1 year, 3 years and 5 years respectively. CONCLUSION: cross over bypasses are technically simple with low morbidity and acceptable results. In addition to widely accepted indications (general or local unfavourable conditions to approach abdominal aorta), cross over bypasses may be considered as satisfactory challenge even in young patients with how operative risk.

Intracavitary cardiac hydatid cyst.

The purpose of this study is to determine the diagnosis means, the surgical management and the prognosis of patients with intracavitary cardiac hydatid cyst. We report a series of seven patients. The diagnosis was orientated by coexisting pulmonary locations in all patients. The cyst was located in the right cardiac chambers. Cardiopulmonary bypass with aortic cross clamping and cardioplegia was necessary in all cases. The postoperative course was satisfactory for all patients. There was a recurrence of pulmonary cysts in all patients after a mean duration of 42 months. Medical treatment (Albendazole) was instituted. One late death occurred at 3 years of follow-up due to chronic right heart failure. In conclusion, cardiac hydatid cysts with intracavitary location must be suspected in patients with pulmonary or systemic embolization. Early surgical treatment is necessary and medical treatment must be instituted after surgery.

[Mycotic aneurysm of the subrenal abdominal aorta: extra anatomical reconstruction in five patients]. / Les anévrismes mycotiques de l'aorte abdominale sous-rénale. Reconstruction extra-anatomique: à propos de 5 cas.

Between 1988 and 2001, five patients with mycotic aneurysm of the abdominal aorta underwent surgery. Extra-anatomical reconstruction with axillo-bifemoral bypass grafting was performed in all patients. The hospital mortality rate was 20%. During the follow-up period two patients presented thrombosis of the axillo-bifemoral bypass, descending aorto-bifemoral bypass was performed in one. Extra-anatomic revascularization is a satisfactory procedure in the treatment of mycotic abdominal aortic aneurysm. The results are acceptable and the prognosis is mainly related to the underlying pathology and the severity of the infection.

[Role of surgery in subaortic stenosis. Report of 56 cases]. / Place de la chirurgie dans le rétrécissement aortique sous-valvulaire. A propos de 56 cas.

INTRODUCTION: Subaortic stenosis is a rare congenital heart disease defined as a left ventricular outflow tract obstruction. We reviewed our surgical experience in this cardiac disease with particularly attention to the different anatomical types of the obstruction. PATIENTS AND METHODS: From January 1987 to December 1998, 56 patients with a mean age of 12.4 years underwent surgical treatment of subaortic stenosis in our Institution. The diagnosis included: subaortic membrane in 44 cases, fibromuscular process in seven and tunnel like hypertrophy in five. RESULTS: There were two hospital deaths (2/56 = 3.5%) and three patients presented postoperative heart block. The first postoperative echocardiographic control showed a mean fall in left ventricleaorta gradient of 78%. In a mean follow-up of 36 months, there were no deaths. All patients periodically controlled, showed an echocardiographic progression of the gradient and it was not related to the different anatomical types of the obstruction. There were no signs of aortic insufficiency progression. CONCLUSION: We can affirm that the surgical treatment of the subaortic obstruction is simple and safe. The medium and long-term progression toward the recurrence is independent to the anatomical type and justify the need of serial echocardiographic control.

[Determining factors in mitral valve reconstructive surgery. Report of 150 cases]. / Les facteurs determinants dans la chirurgie reconstructrice de la valve mitrale. A propos de 150 cas.

150 patients had mitral valve repair for mitral valve incompetence. There were 57 males and 93 females with a mean age of 22 years. 60% of the patients were in Class II NYHA and 40% in Class III and IV. Type I was present in 18 patients, type II in 98 and type III in 34 cases. Mitral repair included correction of valve prolapse, valvular enlargement with pericardial patch and annuloplasty with semi-rigid ring in 128 cases and PTFE patch along the posterior leaflet in 12 cases. The perioperative mortality rate was 2.6%. All patients had early post-operative echocardiography. According to this, mitral regurgitation was absent or tiny in 135 patients, grade II in 10 cases and grade III in 2 cases. It was moderate or important in twelve patients. In the late post-operative period. All the others patients were reoperated upon for mitral dysfunction in a mean time of 37 months. The reason for reoperation was in the majority of the cases the recurrence of mitral regurgitation related to increase of valvular and sub valvular disease. The late mortality rate is 7%. Out of 126 reviewed survivors on the long run, 71 patients are asymptomatic in class I, 53 patients in class II and 2 patients in class III NYHA. The estimated mitral regurgitation by echography in those patients is absent or trivial in 96 cases. grade II in 29 cases and grade III in one case. Mitral valvuloplasty is the preferred procedure in mitral insufficiency surgical management. It is associated to a low early mortality and morbidity rate. Despite the need for reoperation in about 10% of the cases in the long follow-up, mitral repair offers a good quality of life without anticoagulant treatment.

[Revascularization of the lower limbs with extra-anatomic shunts. Report of 80 cases]. / Revascularisation des membres inférieurs par pontages extra-anatomiques. A propos de 80 cas.

UNLABELLED: The extra anatomical bypasses are those which do not follow the usual arterial pathway. The aim of this study is to define the indication of extra anatomical bypasses and to compare them with other revascularisation procedures. In this paper we report a retrospective study carried between January 1988 and December 1999 involving 80 patients (78 men and 2 women) who underwent extra anatomical bypasses for revascularisation of their lower limbs (83 bypasses). The mean age of the patients was 62 years. The indication for revascularisation was chronic arteritis of the lower limbs in 72 patients (90%), infected aneurysms in 6 cases (7.5%) and acute aortic dissection in 2 cases (2.5%). We performed an axillo-unifemoral bypass in 23 cases, an axillo-bifemoral in 17, a crossover ilio-femoral or femoro-femoral bypass in 41 cases, and 2 transobturator ilio popliteal bypass right and left in 1 case. Hospital mortality rate was 10%. Hospital morbidity was about 65%. Limb salvage was 78%. Sixty patients were regularly followed during a mean follow-up of 31 months. Late mortality was 10%. In the end of our study global limb salvage rate was 74%. IN CONCLUSION: extra-anatomical revascularization allows acceptable limb salvage rate along with lower operative risk even in poor state patients.

[Peripheral infected aneurysm: report of 15 cases]. / Les anevrismes infectieux peripheriques: a propos de 15 cas.

In this retrospective study we report 15 cases of peripheral infected aneurysms. The sex ratio was 13/2 and the mean age was 23 years. Patients presented with infection syndrome in 9 cases, vascular mass in 11 cases and limb ischemia in 2 instances. Arterial lesion was documented and confirmed by echography, tomodensitometry and angiography. The infection was recognised by different criteria the main one being micro-organism isolation. In 10 cases aneurysm was secondary to bacterial endocarditis, in 4 it was primary and in one case it was related to arterial catheter procedure. Treatment is based on antibiotics and surgical management by removing of infected aneurysm and arterial restoration whenever possible. Arterial flowerest re-establishment was done in 10 patients among whom 6 by anatomic procedures 4 by extra-anatomic ones. Hospital mortality rate was 13% (2/15), all deaths occurred after cardiac surgery for endocarditis. Two patients were readmitted for adjacent spine infection, one month and one and a half respectively after surgery. One young patient required late surgery (aorto-bifémoral bypass) 24 months after initial treatment and one patient died by intra-duodenal rupture of recurrent false aneurysm. Analysis of our results and literature review allow discussion of clinical, physiopathological and specially therapeutic aspects of infected aneurysm.
