Recurrent varicose veins of the lower limbs after surgery. Role of surgical technique (stripping vs. CHIVA) and surgeon’s experience

Background. Surgical treatment of varicose veins of the lower limbs resolves symptoms and improves quality of life. However, the high recurrence (20-80%) is a costly and complex issue. Patients and methods. This is a retrospective review of 1489 patients with varicose vein of the lower limbs seen at our hospital between January 1980 and December 2005. The aim is to evaluate the effect of surgical technique (stripping vs. CHIVA) and surgeon’s experience in reducing recurrences. Results. With experienced surgeons, CHIVA appears to be more effective than stripping in reducing the recurrence rate (p <0.05). However, when performed by an inexperienced surgeon the results are far worse than those achieved with stripping. Conclusion. There was a clear reduction in recurrences at 5-10 years with CHIVA than with conventional stripping. However, if performed incorrectly, results are far worse with CHIVA. In fact, good results are far more difficult to achieve with CHIVA than with stripping, which is repeatable and easy to perform.

Prosthetic carotid bypass graft for in-stent restenosis performed for post-endarterectomy recurrent stenosis: technical details

Aim. Carotid artery stenting (CAS) is the treatment of choice for recurrent stenosis after carotid endarterectomy (CEA). However a significative incidence of in-stent restenosis could be occurred. Despite classical CEA leads to good results, in selective cases bypass graft may be the best treatment of in-stent restenosis. Case reports. We describe two cases of carotid bypass graft performed to treat a recurrent in-stent stenosis after CAS for post-CEA restenosis. No death and cardiac complication occurred and no cranial nerves impairment was detected. Conclusion. Prosthetic bypass graft is safe and effective in treatment of in-stent recurrent restenosis after CEA restenosis.

Risk factors in reoperative thyroid surgery for recurrent goitre. Our experience

Aim. Reoperative thyroid surgery is an uncommon operation associated with a higher complication rate; we reviewed our series of patients on whom reoperative thyroid surgery was performed.Method. 106 patients had a thyroid reoperation for recurrent multinodular goiter (93 patients), recurrent thyrotoxicosis (3) or suspected malignancy (10); bilateral completion thyroidectomy was performed in 68 cases, lobectomy in 36, removal of a mediastinal recurrence and of a pyramidal remnant in 1 patient respectively. Results. Temporary hypoparathyroidism occurred in 41 patients (38.67%), definitive in 7 (6.6%), transient recurrent laryngeal nerve palsy in 5 (4.71%), permanent nerve palsy in 1 (0.94%); in 3 cases (2.83%) surgical revision of haemostasis was necessary for postoperative haemorrhage. After monolateral surgery we had 13 cases of transient hypoparathyroidism (34.21%), 2 of definitive (5.26%) and 1 transient recurrent laryngeal nerve palsy (2.63%); after bilateral surgery we had 29 cases of transient hypoparathyroidism (42.64%), 5 of definitive (7.35%), 4 of transient recurrent laryngeal nerve palsy (5.88%), 1 of definitive (1.47%) and 3 of postoperative bleeding (4.41%). Conclusions. Reoperative thyroid surgery is a technical challenge with a high incidence of complications. Scarring, edema and friability of the tissues together with distortion of the landmarks make reoperative surgery azardous. A higher risk of complications is described when previous surgery has been performed on both sides. Total thyroidectomy should be considered the procedure of choice for benign multinodular goiter eliminating the potential of a reoperation. Whenever necessary, reoperative hyroidectomy may be performed safely with little morbidity in experienced hands.

Recurrent varicose veins of the legs. Analysis of a social problem

The present study was aimed at assessing the experience of a single referral center with recurrent varicose veins of the legs (RVL) over the period 1993-2008. Among a total of 846 procedures for Leg Varices (LV), 74 procedures were for RVL (8.7%). The causes of recurrence were classified as classic: insufficient crossectomy (13); incompetent perforating veins (13); reticular phlebectasia (22); small saphenous vein insufficiency (9); accessory saphenous veins (4); and particular: post-hemodynamic treatment (5); incomplete stripping (1); Sapheno-Femoral Junction (SFJ) vascularization (5); post-thermal ablation (2). For the “classic” RVL the treatment consisted essentially of completing the previous treatment, both if the problem was linked to an insufficient earlier treatment and if it was due to a later onset. The most common cause in our series was reticular phlebectasia; when the simple sclerosing injections are not sufficient, this was treated by phlebectomy according to Mueller. The “particular” cases classified as 1, 2 and 4 were also treated by completing the traditional stripping procedure (+ crossectomy if this had not been done previously), considered to be the gold standard. In the presence of a SFJ neo-vascularization, with or without cavernoma, approximately 5 cm of femoral vein were explored, the afferent vessels ligated and, if cavernoma was present, it was removed. Although inguinal neo-angiogenesis is a possible mechanism, some doubt can be raised as to its importance as a primary factor in causing recurrent varicose veins, rather than their being due to a preexisting vein left in situ because it was ignored, regarded as insignificant, or poorly evident. In conclusion, we stress that LV is a progressive disease, so the treatment is unlikely to be confined to a single procedure. It is important to plan adequate monitoring during follow-up, and to be ready to reoperate when new problems present that, if left, could lead the patient to doubt the validity and efficacy of the original treatment.

Recurrent gallstone ileus: case report and literature review

The gallstone ileus is a rare complication of cholelithiasis and it represents the 1-4% of small intestinal mechanical obstruction. Gallstone is generally wedged in the terminal ileum, even if unusual locations have been described. The literature reports a very high morbidity and mortality, often because misdiagnosis or delayed diagnosis. There is no unique opinion in literature about the choice between one-stage and two-stage surgery. We report a clinical case that summarizes the diagnostic and therapeutic difficulties of gallstone ileus.

Malignant Otitis Externa and Stroke

Malignant otitis externa (MOE) is an aggressive but benign entity which evolves into skull base osteomyelitis. An 81-year-old female patient was admitted for left hemiparesis and homonymous hemianopia. She complained of headache radiating to the right cervical area. A recent history of recurrent otitis media was present. Head and neck imaging showed an ischemic infarction (right temporo-occipital) and a parapharyngeal soft tissue mass originating in an external and medial ear infection. Culture samples revealed Pseudomonas aeruginosa infection leading to the diagnosis of Malignant otitis externa (MOE). Parenteral antibacterial therapy and hyperbaric oxygen therapy resulted in improvement.

Behind Recurrent Thromboembolic Events

We describe the case of a 68-year-old man, who presented with an ischemic stroke due to cardiac embolization related to mitral valve endocarditis. Blood cultures were always negative and post-operative valve histology did not show microorganisms. The patient also presented further recurrent peripheral embolic events. These clinical aspects were the first sign of a pancreas adenocarcinoma, which was only diagnosed in the clinical autopsy. In conclusion, these clinical findings of recurrent thromboembolic events with no microorganisms isolated suggests the diagnostic of a marantic endocarditis.
