Reasons and management strategies for re-rupture during clipping of ruptured intracranial aneurysms / 中华神经医学杂志

Objective:To explore the reasons and management strategies for re-rupture during clipping of ruptured intracranial aneurysms.Methods:Twenty-one patients with ruptured intracranial aneurysms, accepted clipping by micro-craniotomy in Department of Neurosurgery, Huaihe Hospital of Henan University from May 2015 to October 2021, were chosen in our study. All patients suffered re-rupture at different intraoperative stages. The clinical characteristics, aneurysm parameters, prognoses and complications were retrospectively analyzed. Combined with the relevant literature, the causes and essential treatments for re-rupture at different intraoperative stages were summarized.Results:The average age of these 21 patients was 65 years. All patients were accompanied by disturbance of consciousness at admission. Hunt-Hess grading III was noted in 16 patients and Hunt-Hess grading IV in 5. Anterior communicating artery aneurysms were noted in 12 patients, posterior communicating artery aneurysms in 6, and middle cerebral artery aneurysms in 3; multiple saccular aneurysms were noted in 12 patients and irregular aneurysms in 4; large aneurysms were noted in 18 patients and giant aneurysms in 3. Among the 3 patients with re-rupture at the early stage of clipping (before aneurysm separation), 2 were died and 1 was severely disabled; among the 14 patients with re-rupture at the middle stage of clipping (during separation of aneurysm from its parent artery), 3 had cerebral infarction and 3 had severe disability after surgery; among the 4 patients with re-rupture at the late stage of clipping (after clipping of the aneurysm neck), 2 had cerebral infarction and 2 had severe disability.Conclusion:Patients would trend to have re-rupture during clipping of ruptured intracranial aneurysms in cases that patients have older age, severe diseases and special parameters (locations, shapes, volumes) of the aneurysms, surgeries are operated by inexperienced operator, or surgeries have improper intraoperative operations; during any period of the surgery, the separation and clamping should be fine and gentle to avoid excessive traction.

Free Semitendinosus Tendon Graft in Re-ruptured Achilles Tendon / 대한족부족관절학회지

The acute Achilles tendon rupture usually occurs to the people who participate in sports-related activities between 30 and 40 years of age. Recently surgical repair is the standard treatment in acute Achilles tendon rupture. After the Achilles tendon rupture in the left ankle, a 30-years old young man had been suffered from re-rupturing within three months after the primary repair. 2 years later, right-side Achilles tendon was reruptured after primary repair consequently. In the revision surgery, we performed V-Y advancement of the gastrocnemius-soleus fascia and reinforcement of the semitendinosus tendon. None of the English-literature was reported about using the semitendinosus tendon in revision surgery of the Achilles tendon retear previously. Therefore, we report this case and surgical technique because of the simple technique and the excellent results.

Re-repture after primary flexor tendon repair of the hand / 대한정형외과학회잡지

In the treatment of flexor tendon injury of the hand, re-rupture after primary tendon repair is one of complications which occurs occasionally and so impose burden on both the patient and the surgeon. Authors experienced twelve cases of re-rupture after primary flexor tendon repair of 274 patients from Mar. 1989 to Mar.1996. The incidence of re-rupture after primary flexor tendon repair was 4.4% in author's series. One case happened with slip down injury, and in six cases re-rupture occurred during physical therapy with snapping click sound. However in five cases, the patients conldnt recognize any related causes. In majority of cases, re-ruptures were identified between three and five weeks after primary repair by the surgeon and the patient, so it could be suggested that the attention should be paid for the high possiblity of re-rupture during this period. Operative findings were the resorption and friability of repaired end with insecure suture fixation in two cases, rupture of suture material in four cases and loosening of the knot in six cases. From this study, the authors suggest the importance of knot, and recommend to make more than four knots on suture tie with attention to the tie direction, and advise careful physical therapy according to each patients' different situation. In the treatment of re-rupture, end-to-end re-anastomosis was available in seven cases (59%). In five cases (41%), tendon graft was needed. The clinical result of the re-rupture cases was evaluated by the Stickland evaluation method, and it was satisfactory in 67% of the patients who had the complication of re-rupture.
